The myocardial ATP concentration is significantly decreased in failing hearts, which may be related to the progressive loss of the myocardial total adenine nucleotide pool. The total myocardial interstitial purine metabolites (IPM) in the dialysate of interstitial fluid could reflect the tissue ATP depletion. In rats, postmyocardial infarction (MI) left ventricular (LV) remodeling was induced b...

In sorbent-based hemodialysis, factors limiting a treatment session are urea conversion capacity and sodium release from the cartridge. In vitro experiments were performed to model typical treatment scenarios using various dialyzers and 4 types of SORB sorbent cartridges. The experiments were continued to the point of column saturation with ammonium. The urea nitrogen removed and amount of sodi...

abstract life-threatening infections caused by the encapsulated fungal pathogen cryptococcus neoformans have been increasing steadily over the past 10 years. cryptococcus neoformans is recognized as the most frequent fungal infection of the central nervous system (cns) in immunocompetent as well as immunocompromised patients. we report the development of a semi-nested- pcr-based assay for the d...

Investigating peritoneal membrane alterations caused by peritoneal dialysis fluid during peritoneal dialysis in humans is still intriguing. That is why the study was aimed to provide rabbit peritoneal tissue samples suitable for histological analyses using a modified nonuremic infusion model of peritoneal dialysis on rabbit. A double-lumen central venous catheter, surgically placed in the perit...

Hemodialysis patients are exposed to large volumes of water in the form of dialysate. Contaminants from the dialysate may cross the dialyzer membrane into the blood and have the potential to compromise the adequacy of dialysis. Several chemicals found commonly in drinking water have long been known to be toxic to hemodialysis patients. More recently, it has become apparent that even low levels ...

This paper describes a laboratory-scale study on the use of recirculating cyclones as reaction chambers for dry scrubbing of gaseous HCl with solid slaked lime particles. This gas cleaning system combines a numerically optimized reverse flow gas cyclone (RS_VHE geometry) with a straight-through cyclone concentrator, which simultaneously increases the capture of the solid particles and promotes ...

thalamic pain syndrome, a type of central post-stroke pain (cpsp), may develops after a hemorrhagic or ischemic stroke and results in impairment of the thalamus. there is limited experience about gabapentin in treatment of central pains like cpsp.in a prospective observational study, the intensity of pain was recorded using the numeric rating scale (nrs) at the entrance to the study. patients e...

A spectrophotometric flow-injection analysis (FIA) system for monitoring clinical hemodialysis is demonstrated. The role of a dialysate urea detector incorporated in this bioanalytical system is played by an optical flow-through biosensor based on Prussian Blue film with chemically linked urease forming a monomolecular layer of the enzyme. This pH-enzyme optode-FIA system is useful for the sele...
