The tumour arises from the cells of the proximal renal tubular epithelium. Typical masts are of steel lattice or tubular steel construction. The car has aluminium body on aluminium tubular chassis. Bonds were created by linking components with tubular connectors with locking screws. The chassis was built out of tubular and sheet steel sections. This process is caused by the depolarization of the transverse tubular junctions. Some tires are torus-shaped and attached to tubular rims with adhesive. This is made possible by the flux core in the tubular consumable electrode. Their secondary palate helped them resist bending and torsion of their tubular snouts. A hypha consists of one or more cells surrounded by a tubular cell wall. This was a company that specialised in the fabrication of tubular steel structures. There are four types of renal tubular acidosis. It is the matrix of urinary casts derived from the secretion of renal tubular cells. Sulfamethoxazole is primarily renally excreted via glomerular filtration and tubular secretion. These were composed of enigmatic tubular and frond-shaped, mostly sessile, organisms.
