A transient urinary acidification was induced in the bullfrog proximal tubule by the peritubular administration of ouabain (10(-4) M). Insulin (200 mIU/ml) provoked a prolonged decrease of tubular fluid pH (TFpH), whereas dibutyryl cyclic AMP (10(-4) M) produced a transient increase of TFpH. The above data support the view that the urinary acidification in the proximal tubule is not explained b...

  Distal renal tubular acidosis is a syndrome of abnormal urine acidification and is characterized by hyperchloremic metabolic acidosis, hypokalemia, hypercalciurea, nephrocalcinosis and nephrolithiasis. Despite the presence of persistent hypokalemia, acute muscular paralysis is rarely encountered in males.Here, we will report an eighteen year old male patient who presented with flaccid quadrip...

Abstract The coils of radiant chambers tubular furnaces are operated under especially loaded conditions in terms temperature stress distribution. It is the sections that feed heated to required maximum temperatures. Also, part coil structure may be close proximity burners and exposed an open flame form superheating zones. In this regard, elements can deform prematurely collapse. One most import...

BACKGROUND/AIM To elucidate the mechanism responsible for developing acute kidney injury in patients with diabetes mellitus, we also evaluated the issue of whether advanced glycation endproducts (AGEs) influence the expressions of multi antimicrobial extrusion protein (MATE1/SLC47A1) in tubular cells. MATERIALS AND METHODS To detect changing expression of MATE1/SLC47A1 in dose- and time-depen...

Density functional theory (DFT) calculations were performed to investigate the properties of planar, tubular and conical forms of silicon nanostructures. The evaluated parameters including averaged bond lengths, binding energies, gap energies and dipole moments were then evaluated for the optimized models of study. The results indicated that the bond lengths between silicon atoms are different ...

Tubular KT-joints are quite common in offshore structural design and despite the crucial role of stress concentration factors (SCFs) in evaluating the fatigue performance of tubular joints. However, the SCF distribution in internally ring-stiffened KT-joints have not been investigated and no design equation is currently available to determine the SCFs for this type of joint. In the present pape...

This paper reviews ways in which many artists have constructed large sculptures from tubular elements, ranging from single cylinders to toroidal or knotted structures, to assemblies of a large number of bent tubes. A few parameterized generators are introduced that facilitate design and evaluation of a variety of such sculptural forms.
