26,723,864 | Does microRNA-126 targeting PIK3R2 promote rheumatoid arthritis synovial fibro-blasts proliferation and resistance to apoptosis by regulating PI3K/AKT pathway? | {
"contexts": [
"The purpose of our study was to elucidate the impact of microRNA-126 (miR-126) targeting PIK3R2 gene on cell proliferation and apoptosis of rheumatoid arthritis synovial fibro-blasts (RASFs) by regulating PI3K/AKT signal pathway.",
"The synovial tissue samples of this study were from 55 RA patients undergoing joint replacement and 27 healthy people undergoing joint repair due to trauma. The target genes of miR-126 were collected by the TargetScan and PIK3R2 as the direct target gene of miR-126 was confirmed by dual-luciferase reporter assay system. Our experiment had five groups including the blank control, miR-126 mimic, miR-126 mimic control, miR-126 inhibitor and miR-126 inhibitor control groups. Additionally, real-time quantitative polymerase chain reaction (RT-qPCR), Western-Blot, cell counting kit (CCK-8) and flow cytometry were carried out in this study.",
"Compared with healthy individuals, the RA patients had increased miR-126, but decreased PIK3R2 mRNA expressions in the synovial tissues. Pearson correlation analysis indicated that miR-126 expression was negatively correlated with PIK3R2 mRNA expression (all P<0.05). When compared with the blank group respectively, the miR-126 mimic group had raising cell proportions in S and G2/M phases with reduced rate of cell apoptosis, while the miR-126 inhibitor group had raising cell proportions in G0/G1 and G2/M phases with increased rate of cell apoptosis (all P<0.05). Besides, compared with the blank control group, the miR-126 mimic group had declined expression of PIK3R2 protein with ascended expression of PI3K and p-AKT (all P<0.05), while the miR-126 inhibitor group had increased expression of PIK3R2 protein with decreased expression of PI3K and p-AKT (all P<0.05)."

26,732,661 | Is anti-Mรผllerian hormone gene polymorphism associated with androgen levels in Chinese polycystic ovary syndrome patients with insulin resistance? | {
"contexts": [
"The objective of the study was to investigate whether genetic polymorphisms of the anti-Mรผllerian hormone (AMH) and its specific receptor anti-Mรผllerian hormone type II receptor (AMHRII) were associated with the hormone disorder and phenotype of polycystic ovary syndrome (PCOS).",
"This case-control study included 141 PCOS patients and 123 normal women. Two polymorphisms of AMH and AMHRII and the clinical characteristics of participants such as body mass index (BMI), serum luteinizing hormone (LH), estradiol levels (E2), total testosterone levels (T), and homeostasis model assessment of insulin resistance (HOMA-IR) were analyzed with the case-control sample. Gene-gene interactions of AMH and AMHRII genes were analyzed based multifactor-dimensionality reduction method.",
"A significant difference of AMH gene polymorphisms were observed in IR-PCOS women and controls. The AMH and AMHRII gene polymorphisms were not found a significant difference in non-IR-PCOS and normal groups. To IR-PCOS women, genotypes of AMH were closely related to the serum levels of LH (Pโ=โ0.000), testosterone (Pโ=โ0.000) and HOMA-IR (Pโ=โ0.038), while in the non-IR-PCOS and normal groups, no relationship was found. No impact of AMH and AMHRII gene-gene interactions was demonstrated."

"Although kaffir lime has been reported to exhibit antioxidant and antileukemic activity, little is known about the antimicrobial effect of kaffir lime extract. Because Streptococcus mutans has been known to cause biofilm formation, it has been considered the most important causative pathogen of dental caries. Thus, the effective control of its effects on the oral biofilm is the key to the prevention of dental caries. The aims of the present study were to investigate the effect of kaffir lime leaves extract on biofilm formation and its antibacterial activity on S. mutans.",
"We examined the effect of kaffir lime leaves extract on growth and biofilm formation of S. mutans. For the investigation we used a kaffir lime extract with high phenolic content. The minimum inhibitory concentration of the extract was determined by broth microdilution assay. The inhibitory effect of the test substances on biofilm formation was also investigated by biofilm formation assay and qRT-PCR of biofilm formation-associated genes.",
"Kaffir lime leaves extract inhibits the growth of S. mutans, corresponding to the activity of an antibiotic, ampicillin. Formation of biofilm by S. mutans was also inhibited by the extract. These results were confirmed by the down-regulation of genes associated with the biofilm formation."

"Severe burn is known to induce a series of pathological responses resulting in increased susceptibility to systemic inflammatory response and multiple organ failure, but the underlying molecular mechanism remains unclear at present. The main aim of this study was to expand our understanding of the events leading to circulating leukocyte response after burn by subjecting the gene expression profiles to a bioinformatic analysis.",
"Comprehensive gene expression analysis was performed to identify differentially expressed genes (DEGs) using the expression profile GSE7404 (Mus musculus, circulating leukocyte, 25% of total body surface area (TBSA), full thickness) downloaded from the Gene Expression Omnibus, followed by the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. In addition, a postburn protein-protein interaction (PPI) network was constructed to identify potential biomarkers.",
"Maximum changes in the gene expression profile were detected 1 day post burn. Separate Gene Ontology (GO) functional enrichment analysis for upregulated and downregulated DEGs revealed significant alterations of genes related to biological process such as \"response to stimuli,\" \"metabolic,\" \"cellular and immune system processes,\" \"biological regulation,\" and \"death\" in the leukocyte transcriptome after the burn. The KEGG pathway enrichment analysis showed that the upregulated DEGs were significantly enriched in the nodes of immunorelated and signal transduction-related pathways, and the downregulated genes were significantly enriched for the immunorelated pathways. The PPI network and module analysis revealed that, 1 day after the burn, lymphocyte-specific protein tyrosine kinase (Lck) (downregulated), Jun (upregulated), Cd19 (downregulated), Stat1 (downregulated), and Cdk1 (upregulated) were located centrally in both the PPI network and modules."

"contexts": [
"Retinoblastoma like protein 2 (RBL2) or p130 is a member of the pocket protein family, which is infrequently mutated in human tumours. Its expression is posttranscriptionally regulated and largely G0 restricted. We have previously shown that E6/E7 oncoproteins encoded by human papillomavirus (HPV) type 16, which is a high-risk type for cervical cancer development, must target p130 to promote the host cell to exit from quiescence (G0) state and enter S phase of the cell cycle. P130 is associated with the DREAM (DP, RB-like, E2F and MuvB) complex in G0/G1, which prevents S phase progression by repressing transcription of E2F-regulated genes. E7 proteins could potentially disrupt the p130-DREAM complex through two known mechanisms: direct interaction with p130 or induction of cyclin dependent kinase 2 (CDK2) phosphorylation by interacting with its inhibitor, p21(CIP1).",
"In this study we have used p130 mutants deficient in binding the E7 LXCXE domain (p130mE7), unphosphorylatable by CDK2 (p130PM22) or a combination of both (p130PM22/mE7) to investigate these mechanisms used by E7 proteins to disrupt the p130-DREAM complex and promote cell cycle progression.",
"We found that HPV16 E7 binding to p130 through its LXCXE domain was absolutely required to disrupt p130-DREAM to promote S phase of the cell cycle, as HPV16 E7 was unable to suppress p130mE7 but could suppress p130PM22. In contrast, the E7 protein encoded by a cutaneous HPV type that lacks a functional LXCXE domain, HPV 48 E7, was also able to disrupt p130-DREAM to promote cell cycling, but through the alternative mechanism. Thus, HPV48 E7 could suppress a cell cycle block imposed by p130mE7, but was unable to suppress p130PM22."

We examined the characteristics of COPD patients aged 75 and over compared with patients below 75.",
"A total of 443 patients comprising 252 patients aged <75 years and 191 patients aged โฅ75 years, were enrolled. Emphysematous changes on CT and prevalence of possible pulmonary hypertension were greater in late-elderly patients. The slope of the relationship between CT emphysema densitometry score and forced expiratory volume in 1 s was significantly less steep in the late-elderly than the younger patients (p = 0.002). CAT and total SGRQ scores and the frequency of long-term oxygen therapy were significantly higher in the late-elderly with moderate airflow obstruction compared to those of the younger in the same grade, although the opposite was seen in late-elderly patients with very severe airflow obstruction. Hypertension, aortic aneurysm, prostatic hypertrophy, anemia, and cataract are more prevalent in late-elderly patients."

"contexts": [
"The Radiographic Union Score for Hip (RUSH) is a previously validated outcome instrument designed to improve intra- and interobserver reliability when describing the radiographic healing of femoral neck fractures. The ability to identify fractures that have not healed is important for defining nonunion in clinical trials and predicting patients who will likely require additional surgery to promote fracture healing. We sought to investigate the utility of the RUSH score to define femoral neck fracture nonunion.",
"(1) What RUSH score threshold yields at least 98% specificity to diagnose nonunion at 6 months postinjury? (2) Using the threshold identified, are patients below this threshold at greater risk of reoperation for nonunion and for other indications?",
"A representative sample of 250 out of a cohort of 725 patients with adequate 6-month hip radiographs was analyzed from a multinational elderly hip fracture trial (FAITH). All patients had a femoral neck fracture and were treated with either multiple cancellous screws or a sliding hip screw. Two reviewers independently determined the RUSH score based on the 6-month postinjury radiographs and interrater reliability was assessed with the interclass correlation coefficient (ICC). There was substantial reliability between the reviewers assigning the RUSH scores (ICC, 0.81; 95% confidence interval [CI], 0.76-0.85). The RUSH score is a checklist-based system that quantifies four measures of healing: cortical bridging, cortical fracture disappearance, trabecular consolidation, and trabecular fracture disappearance.. Fracture healing was determined by two independent methods: (1) concurrently by the treating surgeon using both clinical and radiographic assessments as per routine clinical care; and (2) retrospectively by a Central Adjudication Committee using complete obliteration of the fracture line on radiographs alone.

"Hyperglycaemia is a salient feature of poorly controlled diabetes mellitus. Rate of protein glycation is increased with hyperglycaemia leading to long term complications of diabetes. One approach of controlling blood glucose in diabetes targets at reducing the postprandial spikes of blood glucose. The objectives of this study were to assess the in vitro inhibitory effects of Costus speciosus (COS) leaves on ฮฑ-amylase and ฮฑ-glucosidase activities, fructosamine formation, protein glycation and glycation-induced protein cross-linking.",
"Methanol extracts of COS leaves were used. Inhibitory effects on enzyme activities were measured using porcine pancreatic ฮฑ-amylase and ฮฑ-glucosidase from Saccharomyces cerevisiae in the presence of COS extract. Percentage inhibition of the enzymes and the IC50 values were determined. In vitro protein glycation inhibitory effect of COS leaves on early and late glycation products were measured using bovine serum albumin or chicken egg lysozyme with fructose. Nitroblue tetrazolium was used to assess the relative concentration of fructosamine and polyacrylamide gel electrophoresis was used to assess the degree of glycation and protein cross-linking in the reaction mixtures.",
"ฮฑ-Glucosidase inhibitory activity was detected in COS leaves with a IC50 of 67.5ย ฮผg/ml which was significantly lower than the IC50 value of Acarbose (pโ<โ0.01). Amylase inhibitory effects occurred at a comparatively higher concentration of extract with a IC50 of 5.88ย mg/ml which was significantly higher than the IC50 value of Acarbose (pโ<โ0.01). COS (250ย ฮผg/ml) demonstrated inhibitory effects on fructosamine formation and glycation induced protein cross-linking which were in par with 1ย mg/ml aminoguanidine were detected."

"Primary ciliary dyskinesia (PCD) is a rare autosomal recessive genetic disorder characterised by dysfunction of motile cilia. Ciliary dysmotility causes poor mucociliary clearance and leads to impairment of pulmonary function and severe respiratory infections. PCD has no specific therapy. With the aim to permanently restore gene function and normalise ciliary motility, we used gene editing to replace mutated with wild-type sequence in defective cells.",
"The target gene was dynein heavy chain 11 (DNAH11), an essential component of ciliary structure. Airway ciliated cells were collected from two patients with PCD with DNAH11 nonsense mutations and altered ciliary beating and pattern. Repair of the genetic defect was performed ex vivo by site-specific recombination using transcription activator-like effector nucleases (TALENs).",
"In an epithelial cell line engineered to contain the DNAH11 target site, TALENs cleaved over 80% of the mutated DNAH11 sequence and replaced the mutated sequence with wild-type sequence in about 50% of cells. In airway ciliated cells of patients with PCD, site-specific recombination and normalisation of ciliary beating and pattern occurred in 33% and 29% of cells, respectively."

26,719,212 | Is maternal fat , but not lean , mass increased among overweight/obese women with excess gestational weight gain? | {
"contexts": [
"Weight gain in pregnancy is an essential physiologic adaptation that supports growth and development of a fetus and is distributed among lean mass that includes total body water and fat mass gains. Although gestational weight gain provides a source of energy for the mother and fetus, excess gestational weight gain may underlie reported associations between parity and future metabolic disorders and is linked to postpartum weight retention and insulin resistance. Although weight gain often is proposed as a modifiable variable to mitigate adverse maternal and offspring health outcomes, our knowledge of specific maternal body composition changes with weight gain and the potential metabolic consequences is limited. Furthermore, although gestational weight gain alters maternal body composition, the impact of excess weight gain on fat and lean mass is not well-studied. Understanding the accrual of fat and lean body mass may improve our understanding of the role of excessive gestational weight gain and metabolic dysfunction.",
"The purpose of our study was to quantify the relationship between gestational weight gain and maternal fat and lean body mass accrual and to compare fat and lean body mass accrual according to the 2009 Institute of Medicine Guidelines for Gestational Weight Gain in Pregnancy adherence. We hypothesized that exceeding current weight gain guidelines would be associated with greater fat, compared with lean body, mass accrual.",
"This is a secondary analysis of a randomized controlled trial of 49 overweight/obese women; all 49 are included in this secondary analysis. Maternal weight and body composition were collected in early (13 0/6 to 16 6/7 weeks gestation) and late (34 0/7 to 36 6/7 weeks gestation) pregnancy with the use of air densitometry. Correlations were drawn between gestational weight gain and change in fat and lean body mass. We compared change in fat and lean body mass by adherence to the 2009 Institute of Medicine Guidelines for Gestational Weight Gain in Pregnancy. Nonparametric tests and chi-square analyses were performed; a probability value of <.05 was significant.",
"Early pregnancy body mass index was 30.3 kg/m(2) (interquartile range [IQR], 28.5-35.2 kg/m(2)); women gained 9.0 kg (IQR, 5.3-13.2 kg). Overweight and obese women were equally likely to gain excess weight (48% vs 35%; Pย = .6). Weight gain correlated strongly with fat mass change (rย = 0.87; P < .001); women with excess vs adequate vs inadequate weight gain had greater fat mass change overall (5.2 [IQR, 4.2-8.1] vs 0.2 [IQR, -0.4-2.2] vs -2.7 [IQR, -5.2- -0.7] kg, respectively; P < .001) and in all pairwise comparisons. Weight gain also correlated with lean body mass change (rย = 0.52; Pย = .001), but women with excess vs adequate weight gain had similar lean body mass change (8.4 [IQR, 7.2-10.1] vs 7.8 [IQR, 6.0-8.7] kg; Pย = .1)."

"contexts": [
"Recognition and assessment of apical vaginal support defects remains a significant challenge in the evaluation and management of prolapse. There are several reasons that this is likely: (1)ย Although the Pelvic Organ Prolapse-Quantification examination is the standard prolapse staging system used in the Female Pelvic Medicine and Reconstructive Surgery field for reporting outcomes, this assessment is not used commonly in clinical care outside the subspecialty; (2) no clinically useful and accepted definition of apical support loss exists, and (3) no consensus or guidelines address the degree of apical support loss at which an apical support procedure should be performed routinely.",
"The purpose of this study was to identify a simple screening measure for significant loss of apical vaginal support.",
"This was an analysis of women with Pelvic Organ Prolapse-Quantification stage 0-IV prolapse. Women with total vaginal length of โฅ7 cm were included to define a population with \"normal\" vaginal length. Univariable and linear regression analyses were used to identify Pelvic Organ Prolapse-Quantification points that were associated with 3 definitions of apical support loss: the International Consultation on Incontinence, the Pelvic Floor Disorders Network revised eCARE, and a Pelvic Organ Prolapse-Quantification point C cut-point developed by Dietz etย al. Linear and logistic regression models were created to assess predictors of overall apical support loss according to these definitions. Receiver operator characteristic curves were generated to determine test characteristics of the predictor variables and the areas under the curves were calculated.",
"Of 469 women, 453 women met the inclusion criterion. The median Pelvic Organ Prolapse-Quantification stage was III, and the median leading edge of prolapse wasย +2 cm (range, -3 to 12 cm). By stage of prolapse (0-IV), mean genital hiatus size (genital hiatus; mid urethra to posterior fourchette) increased: 2.0 ยฑ 0.5, 3.0 ยฑ 0.5, 4.0 ยฑ 1.0, 5.0 ยฑ 1.0, and 6.5 ยฑ 1.5 cm, respectively (P < .01). Pelvic Organ Prolapse-Quantification points B anterior, B posterior, and genital hiatus had moderate-to-strong associations with overall apical support loss and all definitions of apical support loss. Linear regression models that predict overall apical support loss and logistic regression models predict apical support loss as defined by International Continence Society, eCARE, and the point C; cut-point definitions were fit with points B anterior, B posterior, and genital hiatus; these 3 points explained more than one-half of the model variance. Receiver operator characteristic analysis for all definitions of apical support loss found that genital hiatus >3.75 cm was highly predictive of apical support loss (area under the curve, >0.8 in all models)."

"A total of 2154 children had a mean ยฑ SD of 5.7 ยฑ 3.2 weight and height measurements up to 5 y. Total energy from protein was associated with higher BMI (ฮฒ = 0.043; 95% CI: 0.011, 0.075) and weight (ฮฒ = 0.052; 95% CI: 0.031, 0.074) but not height (ฮฒ = 0.088; 95% CI: -0.038, 0.213) between 21 mo and 5 y. Substituting percentage energy from fat or carbohydrate for percentage energy from protein was associated with decreases in BMI and weight. Protein intake was associated with a trend in increased odds of overweight or obesity at 3 y (OR = 1.10; 95% CI 0.99, 1.22, P = 0.075), but the effect was not statistically significant at 5 y."

"Capsaicin, which is the major pungent principle in chili peppers, is able to induce satiety and reduce caloric intake. The exact mechanism behind this satiating effect is still unknown. We hypothesized that capsaicin induces satiety through the release of gastrointestinal peptides, such as glucagon-like peptide-1 (GLP-1) and peptide YY (PYY), from enteroendocrine cells in the small intestine.",
"We investigate the effects of an intraduodenal capsaicin infusion (1.5 mg pure capsaicin) in healthy volunteers on hunger, satiety, and gastrointestinal symptoms and the release of GLP-1 and PYY.",
"Thirteen participants (7 women) [mean ยฑ SEM age: 21.5 ยฑ 0.6 y; body mass index (in kg/m(2)): 22.8 ยฑ 0.6] participated in this single-blind, randomized, placebo-controlled crossover study with 2 different treatments. During test days, an intraduodenal infusion of either capsaicin or a placebo (physiologic saline) was performed with the use of a nasoduodenal catheter over a period of 30 min. Visual analog scale scores were used to measure hunger, satiety, and gastrointestinal symptoms. Blood samples were drawn at regular intervals for GLP-1 and PYY. Gallbladder volumes were measured with the use of real-time ultrasonography.",
"The intraduodenal capsaicin infusion significantly increased satiety (P-treatment effect < 0.05) but also resulted in an increase in the gastrointestinal symptoms pain (P-treatment ร time interaction < 0.0005), burning sensation (P-treatment ร time interaction < 0.0001), nausea (P-treatment ร time interaction < 0.05), and bloating (P-treatment ร time interaction < 0.001) compared with the effects of the placebo infusion. Satiety scores had a positive correlation with all gastrointestinal symptoms. No differences in GLP-1 and PYY concentrations and gallbladder volumes were observed after the capsaicin infusion compared with after the placebo infusion."

"contexts": [
"One of the main phenomena occurring in cellular membranes during virus infection is a change in membrane permeability. It has been observed that numerous viral proteins can oligomerize and form structures known as viroporins that alter the permeability of membranes. Previous findings have identified such proteins in cells infected with Japanese encephalitis virus (JEV), a member of the same family that Dengue virus (DENV) belongs to (Flaviviridae). In the present work, we investigated whether the small hydrophobic DENV protein NS2B serves a viroporin function.",
"We cloned the DENV NS2B sequence and expressed it in a bacterial expression system. Subsequently, we evaluated the effect of DENV NS2B on membranes when NS2B was overexpressed, measured bacterial growth restriction, and evaluated changes of permeability to hygromycin. The NS2B protein was purified by affinity chromatography, and crosslinking assays were performed to determine the presence of oligomers. Hemolysis assays and transmission electron microscopy were performed to identify structures involved in permeability changes.",
"The DENV-2 NS2B protein showed similitude with the JEV viroporin. The DENV-2 NS2B protein possessed the ability to change the membrane permeability in bacteria, to restrict bacterial cell growth, and to enable membrane permeability to hygromycin B. The NS2B protein formed trimers that could participate in cell lysis and generate organized structures on eukaryotes membranes."

"The usefulness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for evaluating hilar, mediastinal and central parenchymal lesions has been well established. However, its utility for diagnosing lymphoma is controversial. The aim of this study was to evaluate the diagnostic utility of EBUS-TBNA for the definitive diagnosis of de novo lymphoma with subtype classification.",
"Patients with lymphoma who underwent EBUS-TBNA for diagnostic purposes at a single institution between March 2004 and May 2013 were retrospectively reviewed.",
"Of the 971 patients who underwent EBUS-TBNA during the study period, 19 patients, who did not have a previous history of lymphoma, had a final diagnosis of lymphoma. EBUS-TBNA provided a diagnosis accompanied with subtype classification in 6 patients (32%), a suspicious but not definitive classification in 10 patients (53%), and a negative classification in 3 patients (16%). Immunohistochemical staining for definitive diagnosis was performed in 15 of 16 patients (94%), with suspicious results from routine hematoxylin and eosin staining. No procedure-related complications occurred."

In the dynamic condition, the Landolt C moved according to the slow phase eye velocity of the downbeat nystagmus. The Shapiro-Wilk test was used to test for normal distribution and one-way ANOVA for comparison.",
"Ten patients with downbeat nystagmus were included in the study. Median age was 76ย years and the median duration of symptoms was 6.3ย years (SD +/- 3.1y). The mean slow phase velocity was moderate during gaze straight ahead (1.44ยฐ/s, SD +/- 1.18ยฐ/s) and increased significantly in sideward gaze (mean left 3.36ยฐ/s; right 3.58ยฐ/s).

In a clinical project, we identified 12 endometrial cancer patients who were treated with progestin drugs at our institution. Using immunohistochemistry, CD133, ER, PR, and androgen receptor (AR) expression was scored and evaluated for change over time on serial biopsies.",
"CD133+ populations were identified in Ishikawa and KLE cell lines. MPA treatment resulted in a significant reduction in the percentage of live cells (Ishikawa, P=0.036; KLE, P=0.0002), significant increase in apoptosis (Ishikawa, P=0.01; KLE, P=0.0006) and significant decrease in CD133+ populations (Ishikawa, P<0.0001; KLE, P=0.0001). ER, PR, AR and CD133 were present in 96.4%, 96.4%, 89.3% and 100% of patient samples respectively.

Recently, we reported the MPA induced tight junctions (TJs) deregulation which involves MLCK/MLC-2 pathway. Here, we investigated the global histone acetylation as well as gene-specific chromatin signature of several genes associated with TJs regulation in Caco-2 cells after MPA treatment.",
"The epigenetic analysis shows that MPA treatment increases the global histone acetylation levels as well as the enrichment for transcriptional active histone modification mark (H3K4me3) at promoter regions of p38MAPK, ATF-2, MLCK, and MLC-2. In contrast, the promoter region of occludin was enriched for transcriptional repressive histone modification mark (H3K27me3) after MPA treatment. In line with the chromatin status, MPA treatment increased the expression of p38MAPK, ATF-2, MLCK, and MLC-2 both at transcriptional and translational level, while occludin expression was negatively influenced. Interestingly, the MPA induced gene expression changes and functional properties of Caco-2 cells could be blocked by the inhibition of p38MAPK using a chemical inhibitor (SB203580)."

"contexts": [
"Social defeat (SD) stress induces social avoidance and anxiety-like phenotypes. Amygdala is recognized as an emotion-related brain region such as fear, aversion and anxiety. It is conceivable to hypothesize that activation of amygdala is involved in SD-dependent behavioral defects.",
"SD model was established using C57BL/6J mice that were physically defeated by different CD-1 mice for 10ย days. Stressed mice exhibited decreased social interaction level in social interaction test and significant anxiety-like behaviors in elevated plus maze and open field tests. Meanwhile, a higher phosphorylation of PKA and CREB with a mutually linear correlation, and increased Fos labeled cells in the basolateral amygdala (BLA) were observed. Activation of PKA in the BLA by 8-Br-cAMP, a PKA activitor, significantly upregulated pCREB and Fos expression. To address the role of PKA activation on SD stress-induced social avoidance and anxiety-like behaviors, 8-Br-cAMP or H-89, a PKA inhibitor, was continuously administered into the bilateral BLA by a micro-osmotic pump system during the 10-day SD period. Neither H-89 nor 8-Br-cAMP affected the social behavior. Differently, 8-Br-cAMP significantly relieved anxiety-like behaviors in both general and moderate SD protocols. H-89 per se did not have anxiogenic effect in naรฏve mice, but aggravated moderate SD stress-induced anxiety-like behaviors. The antidepressant clomipramine reduced SD-induced anxiety and up-regulated pPKA level in the BLA."

"To investigate the therapeutic and immunoregulatory effects of 1,25-dihydroxyvitamin D (1,25(OH)D3) on 2,4,6-trinitrobenzenesulfonic acid (TNBS) -induced colitis in rats.",
"Experimental colitis induced by enema administration of TNBS plus ethanol was treated with 5-aminosalicylic acid (5-ASA) and/or 1,25(OH)D3. Disease activity was measured using the disease activation index (DAI), colon macroscopic damage index (CMDI), histological colonic damage score, and myeloperoxidase (MPO) activity. The expression of toll-like receptor 9 (TLR9) in the colon was determined by reverse transcription-polymerase chain reaction and immunohistochemistry.",
"Rats with TNBS-induced colitis had significantly elevated DAI, CMDI, histological colonic damage score, and MPO activity (all P<0.001) compared to rats without colitis. Treatment with 5-ASA or 1,25(OH)D3 ameliorated colitis by lowering CMDI (P=0.049, P=0.040, respectively), histological colonic damage score (P=0.010, P=0.005, respectively), and MPO activity (P=0.0003, P=0.0013, respectively) compared with the TNBS group. Combined treatment with 5-ASA and 1,25(OH)D3 significantly decreased MPO activity (P=0.003). 1,25(OH)D3 attenuated colitis without causing hypercalcemia or renal insufficiency. TNBS significantly increased the number of TLR9 positive cells compared to control (P<0.010), while 5-ASA, 1,25(OH)D3, and combined treatment with 5-ASA and 1,25(OH)D3 significantly decreased it compared to TNBS group (all P<0.010). In TNBS group a moderate correlation was observed between MPO activity and the number of TLR9-positive cells (r=0.654, P<0.001)."

Simultaneously, renal function was estimated with five creatinine-based equations (four- and six-variable Modification of Diet in Renal Disease, Cockcroft-Gault, Cockcroft-Gault adjusted for lean body mass, Chronic Kidney Disease Epidemiology Collaboration equation) and body composition was assessed using bioimpedance and dual-energy x-ray absorptiometry.",
"Over a median follow-up of 7.5 months (range 6-17 months), iohexol clearance significantly declined (52.8 vs 44.4 mL/[min ร1.73 m2], P=0.001). This decline was significantly higher in patients receiving mineralocorticoid receptor antagonists at baseline (mean decline -22% of baseline value vs -3%, P=0.037). Mean serum creatinine concentration did not change significantly during follow-up and no creatinine-based renal function estimating equation was able to detect the significant longitudinal decline of renal function determined by iohexol clearance. After accounting for body composition, the accuracy of the equations improved, but not their ability to detect renal function decline."

Endothelial dysfunction may contribute to the pathophysiological processes occurring after STEMI and influence the extension of myocardial necrosis. Endothelial-dependent dysfunction evaluated by peripheral arterial tonometry (PAT) has already showed to be correlated with microvascular coronary endothelial dysfunction. Our purpose was to evaluate the impact of endothelial dysfunction on peak Troponin I (TnI) values, as a surrogate for the extension of myocardial infarction, in patients with STEMI treated with primary angioplasty (P-PCI).",
"58 patients with STEMI treated with P-PCI (mean age 59.0 ยฑ 14.0 years, 46 males) were included. Endothelial function was assessed by reactive hyperaemia index (RHI) determined by PAT. Patients were divided in two groups according to the previously reported RHI threshold for high risk (1.67). The extension of myocardial necrosis was evaluated by peak TnI levels.",
"RHI median value was 1.78 (IQR0.74);25 patients had endothelial dysfunction (RHI b 1.67). The two groups had no significant differences in age, gender, main risk factors and pain-to-balloon time. Patients with an RHI b 1.67 had significant larger infarcts: TnI 73.5 ng/mL (IQR 114.42 ng/mL) versus TnI 33.2 ng/mL (IQR 65.2 ng/mL); p = 0.028.

"contexts": [
"Alterations of synaptic transmission induced by inflammatory activity have been linked to the pathogenic mechanisms of multiple sclerosis (MS). Regulated upon activation, normal T-cell expressed, and secreted (RANTES) is a pro-inflammatory chemokine involved in MS pathophysiology, potentially able to regulate glutamate release and plasticity in MS brains, with relevant consequences on the clinical manifestations of the disease.",
"To assess the role of RANTES in the regulation of cortical excitability.",
"We explored the association of RANTES levels in the cerebrospinal fluid (CSF) of newly diagnosed MS patients with magnetic resonance imaging (MRI) and laboratory measures of inflammatory activity, as well its role in the control of cortical excitability and plasticity explored by means of transcranial magnetic stimulation (TMS), and in hippocampal mouse slices in vitro.",
"CSF levels of RANTES were remarkably high only in active MS patients and were correlated with the concentrations of interleukin-1ฮฒ. RANTES levels were associated with TMS measures of cortical synaptic excitability, but not with long-term potentiation (LTP)-like plasticity. Similar findings were obtained in mouse hippocampal slices in vitro, where we observed that RANTES enhanced basal excitatory synaptic transmission with no effect on LTP."

"contexts": [
"Recent studies found that the circulating high-mobility group box 1 (HMGB1) levels could reflect the disease activity of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). HMGB1 could prime neutrophils by increasing ANCA antigens translocation for ANCA-mediated respiratory burst and degranulation. The current study aimed to investigate whether HMGB1 participates in ANCA-induced neutrophil extracellular traps (NETs) formation, which is one of the most important pathogenic aspects in the development of AAV.",
"NETs were induced by treating neutrophils with HMGB1 and ANCA-positive IgG in vitro. NETs formation was assessed using immunofluorescence microscopy and fluorescence probe. Antagonist for relevant receptors Toll-like receptor (TLR)2, TLR4 and the receptor for advanced glycation end products (RAGE), as well as NADPH oxidase molecules were employed.",
"The percentage of NETs formation was significantly higher in neutrophils stimulated with HMGB1 plus ANCA-positive IgG than that in neutrophils incubated with HMGB1 or ANCA-positive IgG alone. Consistently, compared with the nonstimulated neutrophils, the cell-free DNA (cfDNA) concentration of NETs was significantly increased from 334.09โยฑโ46.89ย ng/ml to 563.32โยฑโ122.07ย ng/ml in the neutrophils incubated with HMGB1 plus MPO-ANCA-positive IgG (Pโ<โ0.001), and from 303.44โยฑโ37.14ย ng/ml to 563.79โยฑโ145.94ย ng/ml in the neutrophils incubated with HMGB1 plus PR3-ANCA-positive IgG (Pโ<โ0.001).

"Salmonella enterica serovar Enteritidis (Salm.ย Enteritidis) encounters mild ethanol stress during its life cycle. However, adaptation to a stressful condition may affect bacterial resistance to subsequent stresses. Hence, this work was undertaken to investigate the influences of ethanol adaptation on stress tolerance of Salm.ย Enteritidis.",
"Salmonella Enteritidis was subjected to different ethanol adaptation treatments (2ยท5-10% ethanol for 1ย h). Cellular morphology and tolerance to subsequent environmental stresses (15% ethanol, -20ยฐC, 4ยฐC, 50ยฐC and 10% NaCl) were evaluated. It was found that 10% was the maximum ethanol concentration that allowed growth of the target bacteria. Ethanol adaptation did not cause cell-surface damage in Salm.ย Enteritidis as revealed by membrane permeability measurements and electron micrograph analysis. Salmonella Enteritidis adapted with 2ยท5-10% ethanol displayed an enhanced resistance to a 15%-ethanol challenge compared with an unchallenged control. The maximum ethanol resistance was observed when ethanol concentration used for ethanol adaptation was increased to 5ยท0%. Additionally, pre-adaptation to 5ยท0% ethanol cross-protected Salm.ย Enteritidis against -20ยฐC, but not against 4ยฐC, 50ยฐC or 10% NaCl."

"contexts": [
"Calcineurin-inhibitors and hepatitis C virus (HCV) infection increase the risk of post-transplant diabetes mellitus. Chronic HCV infection promotes insulin resistance rather than beta-cell dysfunction. The objective was to elucidate whether a conversion from tacrolimus to cyclosporine A affects fasting and/or dynamic insulin sensitivity, insulin secretion or all in HCV-positive renal transplant recipients.",
"In this prospective, single-center study 10 HCV-positive renal transplant recipients underwent 2h-75g-oral glucose tolerance tests before and three months after the conversion of immunosuppression from tacrolimus to cyclosporine A. Established oral glucose tolerance test-based parameters of fasting and dynamic insulin sensitivity and insulin secretion were calculated. Data are expressed as median (IQR).",
"After conversion, both fasting and challenged glucose levels decreased significantly. This was mainly attributable to a significant amelioration of post-prandial dynamic glucose sensitivity as measured by the oral glucose sensitivity-index OGIS [422.17 (370.82-441.92) vs. 468.80 (414.27-488.57) mL/min/m2, p = 0.005), which also resulted in significant improvements of the disposition index (p = 0.017) and adaptation index (p = 0.017) as markers of overall glucose tolerance and beta-cell function. Fasting insulin sensitivity (p = 0.721), insulinogenic index as marker of first-phase insulin secretion [0.064 (0.032-0.106) vs. 0.083 (0.054-0.144) nmol/mmol, p = 0.093) and hepatic insulin extraction (p = 0.646) remained unaltered. No changes of plasma HCV-RNA levels (p = 0.285) or liver stiffness (hepatic fibrosis and necroinflammation, p = 0.463) were observed after the conversion of immunosuppression."

"Cryopreserved PBMCs from 21 natalizumab-treated patients who developed PML and 104 matched natalizumab-treated patients with multiple sclerosis (MS) without PML collected as a part of Biogen clinical trials were retrospectively examined for CD3, CD4, CCR7, CD45RA, and CD62L by flow cytometry.",
"In this cohort, %CD62L in natalizumab-treated patients did not predict PML risk. Natalizumab-treated patients with MS without PML showed highly variable %CD62L upon serial sampling. In the STRATA study, the distribution of %CD62L in samples collected more than 6 months before a PML diagnosis, at diagnosis, and in natalizumab-treated patients without PML overlapped. No statistical threshold for risk could be determined. In addition, we demonstrated that lymphocyte viability strongly affects %CD62L, supporting previous reports that %CD62L is inherently unstable following cryopreservation and is sensitive to sample collection."

"Diabetes has been associated with poor outcomes following elective spine surgery. The purpose of our study was to determine if diabetes predicts worse patient-reported outcomes at two years postoperatively and to evaluate the effect of perioperative blood glucose levels and control on patient-reported outcomes in patients with diabetes.",
"One thousand and five patients undergoing elective spine surgery were included in this prospective cohort study. The presence of diabetes and baseline and one and two-year patient-reported outcomes (Short Form-12 [SF-12], EuroQol-5D [EQ-5D], Oswestry Disability Index [ODI] or Neck Disability Index [NDI], and Numeric Rating Scale [NRS] pain scores) were recorded. The mean blood glucose measurements in patients with diabetes were collected during the postoperative period. Multivariable linear regression analyses were performed to determine predictors of one and two-year outcomes as well as the relationship between perioperative blood glucose and patient-reported outcomes in patients with diabetes.",
"Four hundred and thirty-four patients (43%) had diabetes. When compared with patients without diabetes at two years, patients with diabetes had lower SF-12 Physical Component Summary scores (34.4 points for the diabetic group compared with 38.6 points for the non-diabetic group), lower EQ-5D scores (0.67 for the diabetic group compared with 0.74 for the non-diabetic group), higher ODI or NDI scores (32.1 points for the diabetic group compared with 26.8 points for the non-diabetic group), and higher NRS scores (5.1 points for the diabetic group compared with 4.3 points for the non-diabetic group) (p < 0.05 for all). Although patients with diabetes improved significantly over time, they did not improve to the extent that patients without diabetes did in the ODI or NDI and EQ-5D scores (p < 0.05). Diabetes and preoperative opioid use were independent predictors of decreased SF-12 scores, decreased EQ-5D scores, increased ODI or NDI scores, and increased NRS scores (p < 0.05). Diabetes was associated with increased ODI or NDI (by 6.6 points) and decreased EQ-5D (by 0.1) at two years. Perioperative blood glucose control did not predict outcomes at either one or two years in patients with diabetes."

"contexts": [
"Neisseria meningitidis is a frequent colonizer of the human nasopharynx, with asymptomatic carriage providing the reservoir for invasive, disease-causing strains. Serogroup Y (MenY) strains are a major cause of meningococcal disease. High-resolution genetic analyses of carriage and disease isolates can establish epidemiological relationships and identify potential virulence factors.",
"Whole-genome sequence data were obtained for 99 MenY carriage isolates recovered in the United Kingdom during 1997-2010. Sequences were compared to those of 73 MenY invasive isolates recovered during 2010-2011, using a gene-by-gene approach.",
"Comparisons across 1605 core genes resolved 91% of isolates into one of 8 clusters containing closely related disease and carriage isolates. Six clusters contained carried meningococci isolated during 1997-2001, suggesting temporal stability. One cluster of isolates, predominately sharing the designation Y: P1.5-1,10-1: F4-1: ST-1655 (cc23), was resolved into one subcluster with 86% carriage isolates and a second with 90% invasive isolates. These subclusters were defined by specific allelic differences in 5 core genes encoding glycerate kinase (glxK), valine-pyruvate transaminase (avtA), superoxide dismutase (sodB), and 2 hypothetical proteins."

26,747,707 | Does transcriptional Regulation of miR-31 by Oncogenic KRAS mediate Metastatic Phenotypes by Repressing RASA1? | {
"contexts": [
"Activating KRAS mutations are nearly ubiquitous in pancreatic cancer occurring in more than 95% of clinical cases. miRNAs are small noncoding RNAs that regulate gene expression by binding sequences within the 3'UTRs of target mRNAs. An integral role for miRNAs in cancer pathogenesis is well established; however, the role of miRNAs in KRAS-mediated tumorigenesis is poorly characterized. Here it is demonstrated that expression of miR-31 is coupled to the expression of oncogenic KRAS and activity of the MAPK pathway. miR-31 is highly expressed in patient-derived xenografts and a panel of pancreatic and colorectal cancer cells harboring activating KRAS mutations. The miR-31 host gene is a large noncoding RNA that correlates with miR-31 expression and enabled identification of the putative miR-31 promoter. Using luciferase reporters, a minimal RAS-responsive miR-31 promoter was found to drive robust luciferase activity dependent on expression of mutant KRAS and the transcription factor ELK1. Furthermore, ELK1 interacts directly with the endogenous miR-31 promoter in a MAPK-dependent manner. Expression of enforced miR-31 significantly enhanced invasion and migration of multiple pancreatic cancer cells resulting from the activation of RhoA through regulation of the miR-31 target gene RASA1. Importantly, acute knockdown of RASA1 phenocopied enforced miR-31 expression on the migratory behavior of pancreatic cancer cells through increased RhoA activation."

"contexts": [
"miRNAs have important roles in regulating cancer stem cell (CSC) properties and are considered to be potential therapeutic targets. However, few studies have focused on miRNAs which are specifically related to colon CSCs. Here, a PCR-based miRNA profiling analysis of normal colon stem cells (NCSC) and colon CSCs (EpCAMโบ/CD44โบ/CD66aโป) identified miRNAs which regulate colon CSC properties. Interestingly, miRNA-137 (miR-137) expression was downregulated in the colon CSCs compared with NCSCs, while doublecortin-like kinase 1(DCLK1) mRNA was highly expressed in the colon CSCs but low in the NCSCs. In fact, DCLK1-positive cancer cells were widely distributed in clinically resected colon cancer specimens, while DCLK1-positve epithelial cells were rarely detected in normal colon tissues including the crypt bottoms. Luciferase assay and immunoblot analysis revealed that miR-137 regulated DCLK1 gene expression. Transduction of exogenous miR-137 suppressed the development of colon cancer organoids in vitro and the tumorigenicity of colon cancer cells in vivo without affecting the growth of normal intestinal organoids. Furthermore, the suppression of miR-137 enhanced the organoid development of normal colon cells. These data demonstrate that miR-137 has the capacity to suppress the tumorigenicity of colon CSCs and that maintained expression of miR-137 in NCSCs contributes to suppressing uncontrolled cell proliferation through the inhibition of DCLK1 expression."

In this study, the mechanism of action of isoalantolactone as well as its radiosensitizing effect was investigated in UMSCC-10A cells.",
"The radiosensitization of UMSCC-10A cells treated with isoalantolactone was analyzed by colony formation assay. The radiosensitization effects of isoalantolactone on cell proliferation, cell cycle and apoptosis regulation were examined by BrdU incorporation assay, DNA content assay and flow cytometry, respectively. Western blotting was performed to determine the effects of isoalantolactone combined with radiation on the protein expression of Mek, extracellular signal-regulated kinase (Erk1/2) as well as phosphorylated Mek and Erk1/2. Erk1/2 knockdown by siRNA was used to confirm that isoalantolactone specifically inhibited the activation of Erk1/2 signaling pathway in UMSCC-10A cells.",
"Isoalantolactone enhanced the radiosensitivity of UMSCC-10A cells; the sensitivity enhanced ratios (SERs) were 1.44 and 1.63, respectively, for 2.5 and 5 ฮผM. Moreover, isoalantolactone enhanced radiation-induced cell proliferation and apoptosis and cell cycle arrested at G2/M phase. Furthermore, no marked changes were observed in the expression of total Erk1/2 and Mek protein after radiation treatment. However, isoalantolactone was significantly reduced radiation-induced the phosphorylation of Erk1/2, whereas it altered the phosphorylation of Mek to a lesser extent. In addition, the radiosensitivity of UMSCC-10A cells with Erk1/2 knockdown was increased. Isoalantolactone cannot further prevent the proliferation of UMSCC-10A cells with Erk1/2 knockdown which other mechanism regulated cell proliferation."

The use by roots of these three natural Fe sources (Fe-citrate, Fe-PS and Fe complexed to water-extractable humic substances, Fe-WEHS) have been already studied at physiological level but the knowledge about the transcriptomic aspects is still lacking.",
"The (59)Fe concentration recorded after 24ย h in tissues of tomato Fe-deficient plants supplied with (59)Fe complexed to WEHS reached values about 2 times higher than those measured in response to the supply with Fe-citrate and Fe-PS. However, after 1ย h no differences among the three Fe-chelates were observed considering the (59)Fe concentration and the root Fe(III) reduction activity. A large-scale transcriptional analysis of root tissue after 1ย h of Fe supply showed that Fe-WEHS modulated only two transcripts leaving the transcriptome substantially identical to Fe-deficient plants.

"contexts": [
"Due to their unique properties, adipose derived stem cells (ADSCs) obtain promising potential to enhance nerve regeneration. The aim of this study was to investigate if fibrin-glue embedded ADSCs were a beneficial adjunct to primary coaptation in a rat sciatic nerve model.",
"Fifty male Lewis rats underwent sciatic nerve transection and subsequent epineural suture repair. The treatment group received ADSCs re-suspended in fibrin glue, while the control group received fibrin glue only. After 7, 21, 35, and 63 days, analysis involved axon count, myelin sheath thickness as well as N- and G-ratios. Additionally, muscle weight quotient (operated vs. non-operated site of the same animal) was calculated and compared between treatment and control groups. For co-detection of vital ADSCs, vessel walls, and Schwann cells, immunolabeling was performed with CM-DiI, SMA, and S-100 antibodies, respectively.",
"ADSCs led to a significant increase of myelinization at day 21 (0.508โยฑโ0.085 ฮผm vs. 0.381โยฑโ0.044 ฮผm, Pโ=โ0.025) and day 35 (0.872โยฑโ0.09 ยตm vs. 0.495โยฑโ0.078 ยตm; Pโ=โ0.01) after surgery. Axon count was significantly increased at day 21 (420โยฑโ119 vs. 129โยฑโ63; Pโ=โ0.003) and day 63 (284โยฑโ137 vs. 111โยฑโ26; Pโ=โ0.046) after surgery. N- and G-ratios were significantly different compared with control indicating enhanced nerve regeneration due to ADSC treatment at each time point (Pโ<โ0.05). Muscle weight quotient was significantly higher in the treatment group compared with the control at day 21 (44.01%โยฑโ6.16% vs. 35.03%โยฑโ2.61%; Pโ=โ0.014) and day 63 (65.49%โยฑโ2.81% vs. 58.79%โยฑโ4.06%; Pโ=โ0.009) after surgery. Co-detection of immunolabeled cells showed vital ADSCs at the neuronal repair site and in close proximity to intraneuronal vessels indicating active participation of ADSCs in the process of nerve regeneration and associated angiogenesis."

"Recently a single-center study suggested that hypertension after stroke in children was a risk factor for mortality. Our goal was to assess the association between hypertension and outcome after arterial ischemic stroke in children from a large national sample.",
"Using the Healthcare Cost and Utilization Project Kids' Inpatient Database, children (1-18 years) with a primary diagnosis of ischemic stroke (International Classification of Diseases, Ninth Revision [ICD-9] codes 433-437.1) who also had a diagnosis of elevated blood pressure (ICD-9 code 796.2) or hypertension (ICD-9 codes 401 and 405) from 2003, 2006, and 2009 were identified. Clinical characteristics, discharge outcomes, and length of stay were assessed. Multivariable logistic regression was used to assess the relationship between hypertension and in-hospital mortality or discharge outcomes.",
"Of 2590 children admitted with arterial ischemic stroke, 156 (6%) also had a diagnosis of hypertension. Ten percent of children with hypertension also had renal failure. Among patients with arterial ischemic stroke, hypertension was associated with increased mortality (7.4% vs. 2.8%; P = 0.01) and increased length of stay (mean 11 ยฑ 17 vs. 7 ยฑ 12 days; P = 0.004) compared with those without hypertension. After adjusting for age, sex, intubation, presence of a fluid and electrolyte disorder, and renal failure, children with hypertension had an increased odds of in-hospital death (odds ratio 1.2, 95% confidence interval [1.1-3.3, P = 0.04])."

"S. lugdunensis binding to VWF, collagen, and endothelial cells was studied in a parallel flow chamber in the absence and presence of platelets. In vivo adhesion of S. lugdunensis was evaluated in a mouse microvasculature perfusion model and a new mouse model of endocarditis.",
"Contrary to other coagulase-negative staphylococci, S. lugdunensis bound to VWF under flow, thus enabling its adhesion to endothelial cells and to the subendothelial matrix. In inflamed vessels of the mesenteric circulation, VWF recruited S. lugdunensis to the vessel wall. In a novel endocarditis mouse model, local inflammation and the resulting release of VWF enabled S. lugdunensis to bind and colonize the heart valves."

Upon admission, patients' sociodemographic data, type of fracture, American Society of Anesthesiologists (ASA) score, health-related quality of life scores (EQ-5D index) and Mini-Mental State Examination (MMSE) scores were recorded, among other parameters. Correlational analysis was performed on all potential variables to identify relevant predictor variables of 1-year survival. Univariate regression analysis was performed on all selected variables, followed by a multivariate analysis for variables that were significant in the univariate analysis. The final score was developed by converting the ฮฒ-coefficients of each variable from the multivariate analysis into a scoring system.",
"For 391 hip fracture patients, complete data were available at the time of the 1-year follow-up. In multivariate regression analysis, independent predictors of 1-year survival were lower ASA score, higher pre-fracture EQ-5D index, higher MMSE score, and female gender. The different variables were weighted according to their ฮฒ-coefficient to build the prognostic score, which ranged from 0 to 10 points. The ROC curve for 1-year mortality after hip fracture showed an area under the curve of 0.74 (R (2)โ=โ0.272; 95ย % CI 0.68-0.79; pโ<โ0.001)."

"contexts": [
"To investigate the effects of ฮฒ-glucan on the maturation and migration of bone marrow-derived dendritic cells (BMDCs).",
"BMDCs were isolated from mouse bone marrow cells in vitro and induced by ฮฒ-glucan for maturation. The expressions of cell surface markers were detected by flow cytometry (FCM). The cytokines (IL-6, IL-12p40, tumor necrosis factor ฮฑ) in the supernatants were measured by ELISA, and the expressions of intracellular CC chemokine receptor 1 (CCR1), CCR2, CCR5, CCR7 were determined by real-time quantitative PCR. Furthermore, the chemotactic response to CC chemokine ligand 19 (CCLl9) and CCL21, i.e. CCR7-1igands, was measured by Transwell(TM) migration assay. Moreover, the number of migrated cells in the draining lymph nodes was analyzed by FCM.",
"Compared with the control group, the expressions of co-stimulation molecules (MHC II, CD40, CD80, CD86) on BMDCs were up-regulated in the presence of ฮฒ-glucan. Furthermore, ฮฒ-glucan could prompt BMDCs to secret high levels of IL-6, TNF-ฮฑ, IL-12 p40 and increase the production of CCR7 mRNA. After ฮฒ-glucan treatment, BMDCs were more sensitive to CCL19/CCL21. The number of BMDCs migrated from subcutaneous injection site into the draining lymph nodes significantly increased in ฮฒ-glucan group."

"contexts": [
"MiRNAs have been proposed to be key regulators of tumorigenesis, progression and metastasis. However, their effect and prognostic value in gastric cancer is still poorly known.",
"Gastric cancer cell lines were cultured. Tissue samples obtained from 36 gastric cancer patients were used for quantitative real-time PCR (qRT-PCR) analysis. The tissue microarrays (TMAs) consisted of 126 cases of gastric carcinoma that were used for In situ hybridisation (ISH). Lentivirus plasmids were co-transfected into 293FT cells. Cell migration was examined using wound-healing assays. Statistical analyses were performed using SPSS16.0 software.",
"In this study, we found that the expression levels of miR-493 were strongly down-regulated in gastric cancer and were associated with clinical stage and the presence of lymph node metastases. Moreover, miR-493 might independently predict OS and RFS in gastric cancer. We further found that up-regulation of miR-493 inhibited the proliferation and metastasis of gastric cancer cells, in vitro and in vivo. In addition, miR-493 directly targeted RhoC, which resulted in a marked reduction of the expression of mRNA and protein. This effect, in turn, led to a decreased ability of growth, invasion and metastasis in gastric cancer cells."

"contexts": [
"Initially identified as a molecule that regulates the final step of glycolysis, the M2 isoform of pyruvate kinase (PKM2) was recently reported to have a central role in the metabolic reprogramming of cancer cells as well as participating in cell cycle progression and gene transcription. Despite intensive efforts, the intricate molecular mechanisms through which PKM2 regulates tumor progression remain elusive.",
"The proliferation and apoptosis of various pancreatic cancer cells using lentiviral-mediated PKM2 abrogation were assessed in vitro via Western blot and flow cytometric assay while the in vivo experiments involved tumor xenograft on chicken chorionallantoic membranes and immunohistochemistry on human tissue specimens. In order to decipher the molecular mechanism of HIF-1ฮฑ and p65/RelA regulation by PKM2 in cancer cells cultivated in hypoxic atmosphere or normoxia we involved various biochemical assays such as Western blotting, immunoprecipitation, reporter gene assay and ELISA.",
"Strong expression of PKM2 was observed in 68ย % of human pancreatic adenocarcinoma specimens and almost all analyzed pancreatic cancer cell lines. Abrogation of PKM2 resulted in impaired proliferation and augmented apoptosis in vitro as well as impaired tumor growth and decreased blood vessel formation in vivo. Furthermore, deletion of PKM2 negatively impacted hypoxia-induced HIF-1ฮฑ accumulation and promoter activity ultimately resulting in impaired secretion of VEGF."

However, the role of ROC1 in the malignant progression of bladder cancer remained unknown.",
"ROC1 expression in cancer cells was knocked down by siRNA silencing. The effects of ROC1 silencing were evaluated by in vitro assays for cell migration and by an in vivo mouse metastasis model. Epithelial-mesenchymal transition (EMT) induction was evaluated by immunofluorescence staining and western blotting of EMT-associated proteins. ROC1 expression in human tumours was further evaluated by immunohistochemical analysis.",
"ROC1 knockdown suppresses bladder cancer cell migration by inhibiting EMT. ROC1 knockdown inhibited EMT by inhibiting mammalian target of rapamycin (mTOR) activity via the accumulation of the mTOR-inhibitory protein DEPTOR, a CRL substrate. DEPTOR knockdown partially rescued ROC1 knockdown-inhibited EMT and the ROC1-induced inhibition of cancer cell migration. Furthermore, in vivo studies using a nude mouse metastasis model confirmed the in vitro data. Finally, tissue microarray analysis of clinical bladder cancer specimens indicated a positive correlation between ROC1 expression and EMT."

"Demyelination and axonal degeneration, hallmarks of multiple sclerosis (MS), are associated with the central nervous system (CNS) inflammation facilitated by C-X-C motif chemokine 12 (CXCL12) chemokine. Both in MS and in experimental autoimmune encephalomyelitis (EAE), the deleterious CNS inflammation has been associated with upregulation of CXCL12 expression in the CNS. We investigated the expression dynamics of CXCL12 in the CNS with progression of clinical EAE and following spontaneous recovery, with a focus on CXCL12 expression in the hippocampal neurogenic dentate gyrus (DG) and in the corpus callosum (CC) of spontaneously recovered mice, and its potential role in promoting the endogenous myelin/neuronal repair capacity.",
"CNS tissue sections from mice with different clinical EAE phases or following spontaneous recovery and in vitro differentiated adult neural stem cell cultures were analyzed by immunofluorescent staining and confocal imaging for detecting and enumerating neuronal progenitor cells (NPCs) and oligodendrocyte precursor cells (OPCs) and for expression of CXCL12.",
"Our expression dynamics analysis of CXCL12 in the CNS with EAE progression revealed elevated CXCL12 expression in the DG and CC, which persistently increases following spontaneous recovery even though CNS inflammation has subsided. Correspondingly, the numbers of NPCs and OPCs in the DG and CC, respectively, of EAE-recovered mice increased compared to that of naรฏve mice (NPCs, p < 0.0001; OPCs, p < 0.00001) or mice with active disease (OPCs, p < 0.0005). Notably, about 30 % of the NPCs and unexpectedly also OPCs (~50 %) express CXCL12, and their numbers in DG and CC, respectively, are higher in EAE-recovered mice compared with naรฏve mice and also compared with mice with ongoing clinical EAE (CXCL12(+) NPCs, p < 0.005; CXCL12(+) OPCs, p < 0.0005). Moreover, a significant proportion (>20 %) of the CXCL12(+) NPCs and OPCs co-express the CXCL12 receptor, CXCR4, and their numbers significantly increase with recovery from EAE not only relative to naรฏve mice (p < 0.0002) but also to mice with ongoing EAE (p < 0.004)."

"An alternation of sympathetic and vagal nervous activity has been suggested to be one possible mechanism of neurogenic pulmonary edema (NPE) in patients with subarachnoid hemorrhage (SAH). The study aimed to explore if sympathovagal modulation assessed by frequency domains of heart rate variability (HRV) is associated with impending NPE in patients with SAH.",
"Two hundred forty-eight consecutive spontaneous SAH adult patients were included in this single-center cohort study. A continuous 10-min electrocardiography for HRV analysis was recorded. The patients were stratified into NPE and non-NPE based on serially clinical and radiologic findings within 24ย h. Seven frequency domains of HRV were compared between these 2 groups.",
"Compared to the non-NPE (nย =ย 212), the NPE (nย =ย 36) had significantly higher mean arterial pressure, higher World Federation of Neurological Surgeons (WFNS) class, higher Hunt-Hess scale, lower total power (TP), lower very low-frequency component, lower low-frequency component, lower normalized low-frequency component (LFย %), higher normalized high-frequency component, and lower low-frequency component/high-frequency component ratio. Multiple logistic regression model identified WFNS class (OR 4.048; 95ย % CI 1.589-10.311), LFย % (OR 0.933; 95ย % CI 0.910-0.958), and TP (OR 0.995; 95ย % CI 0.992-0.998) as the significant variables associated with occurrence of NPE. The area under receiver operating characteristic curves of LFย % and TP were found to be 0.838 (95ย % CI 0.774-0.901) and 0.653 (95ย % CI 0.557-0.749), respectively."

Tumor size, central depression, invasion depth, lymphatic and venous permeation, mitotic activity, nuclear abnormality, Ki-67 labeling index, and World Health Organization grading classification (G1 or G2) were compared between the groups. Patients underwent endoscopic submucosal resection with a ligation device, transanal full-thickness surgical resection, or radical surgery.",

"contexts": [
"Chemokine (C-C motif) ligand 2 (CCL2) is known to recruit monocytes and macrophages to sites of inflammation. Recent studies suggest CCL2 is overexpressed in multiple cancer types and may play a role in the tumor progression. The aim of this study was to assess the association between CCL2 expression and the risk of recurrence after surgery in patients with clear-cell renal cell carcinoma (ccRCC).",
"This study included 268 ccRCC patients who underwent nephrectomy at a single institute between 2001 and 2004. Clinicopathologic variables and recurrence-free survival (RFS) were recorded. CCL2 expression levels were evaluated by immunohistochemical staining in tumor tissues. Kaplan-Meier method was applied to compare survival curves. Cox regression models were fitted to analyze the effect of prognostic factors on recurrence-free survival (RFS). Harrell's concordance index was calculated to assess predictive accuracy.",
"High CCL2 expression was associated with a greater risk of recurrence in ccRCC patients (P<0.001). Multivariate analysis confirmed that CCL2 expression was an independent prognostic factor for RFS (P = 0.045). The predictive accuracy of the Leibovich prognostic score was improved when CCL2 expression was added (0.76 vs. 0.71, P<0.001). Notably, the improvement in prediction was more pronounced in patients with low-risk disease. A nomogram integrating CCL2 expression and pathologic factors was then constructed, which predicted 5- and 10-year RFS well for ccRCC patients."

Patients who had a history of genitourinary malignancy and/or recent surgical urologic intervention were excluded. Multiple variables were examined for association with death.",
"Thirty-three patients met our inclusion criteria, with a mean age of 48 years (23-65). Common malignancies included acute myelogenous leukemia (17/33, 57%), acute lymphocytic leukemia (3/33, 10%), and peripheral T cell lymphoma (3/33, 10%). Median time from stem cell transplant to need for CBI was 2.5 months (0 days-6.6 years). All patients had previously undergone chemotherapy (33/33, 100%) and 14 had undergone prior radiation therapy (14/33, 42%). Twenty-eight patients had an infectious disease (28/33, 85%), most commonly BK viremia (19/33, 58%), cytomegalovirus viremia (17/33, 51%), and bacterial urinary tract infection (8/33, 24%). Twenty-two patients expired during the same admission as CBI treatment (22/33 or 67% of total patients, 22/28 or 79% of deaths), with a 30-day mortality of 52% and a 90-day mortality of 73% from the start of CBI."

26,739,353 | Do two COX-2 inhibitors induce apoptosis in human erythroleukemia K562cells by modulating NF-ฮบB and FHC pathways? | {
"contexts": [
"Leukemia is distinguished by abnormal proliferation of leukocytes. Although there has been some progress in developing novel cancer therapies, no significant improvement was observed in the overall survival rate over the last decade. Selective cyclooxygenase-2 (COX-2) inhibitors are known to inhibit tumor growth by exerting antimetastatic and antiangiogenic effects through inhibition of COX -dependent and independent pathways. The ability of two new triaryl-oxadiazole derivatives, compounds A (3-(4-chlorophenyl) -5-(4-flurophenyl)-4-Phenyl-4,5-dihydro-1,2,4-oxadiazole) and B (3,5-bis(4-chlorophenyl)-4-Phenyl-4,5-dihydro-1,2,4-oxadiazole), to induce apoptosis in human erythroleukemia K562 cells was evaluated and the upstream mechanism was investigated.",
"K562 cells were treated with compounds A and B at their IC50 concentrations and analyzed by DAPI staining and Annexin-V-FLUOS labelling solution. Nuclear factor kappa-B (NF-ฮบB) activation was evaluated by TransAM kit. Cyclooxygenase-2 (COX-2), Caspase-3, Bax, Bcl-2, ferritin heavy chain (FHC), extra cellular signal-regulated kinase (ERK), p-ERK and early growth response protein-1 (Egr1) levels were determined using Western blotting, while c-Myc mRNA level was investigated by RT-PCR.",
"Changes in nuclear morphology and the increased annexin-V/PI staining revealed the apoptotic cell death in compounds A- and B-treated K562 cells. A significant reduction in NF-ฮบB activity as well as FHC and p-ERK levels were detected in these cells. No change was observed in the levels of Bax, Bcl-2, Caspase-3, COX-2, c-Myc and Egr1, following treatment with the two compounds. Collectively, compounds A and B potentiate apoptosis as shown by DAPI staining, flowcytometry, FHC and p-ERK downregulation and NF-ฮบB inactivation."

"Seven patients undergoing lower limb amputation for peripheral artery disease or who died and donated their bodies to science donated 11 tibial arteries (5 anterior, 6 posterior) for this study. All arteries were atherosclerotic by visual inspection. The arteries underwent ex vivo balloon angioplasty and thereafter were cut into rings and studied on wire myographs where the rings were stretched and tension was recorded. After treatment with vonapanitase 2 mg/mL or vehicle control, myography was repeated and the rings were then subject to elastin content measurement using a desmosine radioimmunoassay and elastic fiber visualization by histology. The wire myography data were used to derive compliance, stress-strain, and incremental elastic modulus curves.",
"Vonapanitase treatment reduced elastin (desmosine) content by 60% and decreased elastic fiber histologic staining. Vonapanitase-treated rings experienced less tension at any level of stretch and as a result had shifts in the compliance and stress-strain curves relative to vehicle-treated rings. Vonapanitase treatment did not alter the incremental elastic modulus curve."

All patients with MS underwent structural MRI and clinical examinations (Expanded Disability Status Scale [EDSS] and Multiple Sclerosis Functional Composite [MSFC]). Whole-brain voxel-wise and cerebellar volumetry were performed to assess differences in regional brain volumes between genotype groups. Resting-state fMRI was acquired from 62 patients with MS to evaluate differences in cerebellar functional connectivity. All participants were genotyped for 4 potentially functional SCN10A polymorphisms.",
"Two SCN10A polymorphisms in high linkage disequilibrium (r(2) = 0.95) showed significant association with MSFC performance in patients with MS (rs6795970: p = 6.2 ร 10(-4); rs6801957: p = 0.0025). Patients with MS with rs6795970(AA) genotype performed significantly worse than rs6795970(G) carriers in MSFC (p = 1.8 ร 10(-4)) and all of its subscores. This association was independent of EDSS and cerebellar atrophy. Although the genotype groups showed no difference in regional brain volumes, rs6795970(AA) carriers demonstrated significantly diminished cerebellar functional connectivity with the thalami and midbrain.

"The diagnosis and treatment of cancer is a continuum, with multiple steps and interfaces between patients and providers allowing for potential delays in cancer recognition and subsequent treatment. The diagnosis and treatment of hepatocellular carcinoma (HCC) is especially prone to missteps along the continuum, leading to treatment delays due to non-tissue-based diagnosis and multiprovider treatments. The aim of this study was to evaluate outcome measures after implementation of a voice messaging system (VMS) designed to streamline patient referrals to downstream treatment physicians and ultimately reduce delays in HCC treatment, thereby improving outcome measures.",
"A retrospective study of outpatients with HCC was conducted in a safety net hospital between February 2008 and January 2012. In February 2010, VMS notification of HCC to the ordering physician and downstream treating physicians was implemented. Patients were divided into 2 groups: (1) preintervention: diagnosis 2 years before implementation or failure of notification following implementation, and (2) postintervention: diagnosis 2 years after implementation. Demographics, tumor characteristics, treatment, and survival were compared.",
"This study included 96 patients diagnosed with HCC: 51 in the preintervention group and 45 in the postintervention group. The main cause of chronic liver disease was HCV infection, and no differences in symptoms, liver dysfunction, tumor characteristics, or treatment were observed between groups. The time from diagnosis to clinic contact (0.5 vs 2.9 months; P=.003) and time from detection to treatment (2.2 vs 5.5 months; P=.005) was significantly shorter after implementation of the VMS. Barcelona Clinic Liver Cancer stage A status (hazard ratio [HR], 3.1; 95% CI, 2, 6), treatment (HR, 1.9; 95% CI, 1, 4), and VMS (HR, 1.8; 95% CI, 1, 3) were independently associated with overall survival.

"contexts": [
"To investigate the predictive value of striatal dopamine turnover in patients with de novo Parkinson disease (PD) for the onset of later motor complications.",
"This retrospective, observer-blinded cohort study followed up 31 patients with early PD who completed quantitative (18)F-dopa PET imaging to measure striatal (18)F-dopa uptake (Kocc) and effective distribution volume ratio (EDVR) as the inverse of dopamine turnover prior to antiparkinsonian treatment. The onset of wearing-off and dyskinesias was determined based on blinded clinical assessments and patient records. The predictive value of baseline PET measures for motor complications was evaluated using Cox proportional hazard models.",
"During a mean follow-up time of 6.8 years, 18 (58.1%) patients developed wearing-off, 11 (35.5%) dyskinesia, and 20 (64.5%) any motor complication. Patients with dyskinesia and any motor complication showed lower baseline EDVR (higher dopamine turnover) in the putamen than those without dyskinesias and any motor complication, with differences most markedly present in the posterior putamen. Baseline EDVR in the whole and the posterior putamen predicted development of motor complications with an increasing risk with lower EDVR (higher dopamine turnover), whereas EDVR in other regions and Kocc did not correlate with motor complications. Correspondingly, Kaplan-Meier curves showed reduced survival from motor complications in patients with lower baseline EDVR (higher dopamine turnover) in the posterior putamen with ongoing levodopa treatment and disease duration."
