Background and purpose: Using practical and non-invasive methods to improve the adequacy of dialysis (i.e. Kt/V) can increase the quality of life and decrease the mortality and morbidity rate in patients under hemodialysis. This study was conducted to investigate the effect of intermittent normal saline bolus on adequacy of dialysis. Materials and methods: In this randomized controlled...
BACKGROUND Inadequacy of dialysis is one of the main causes of death in hemodialysis patients. Some studies have suggested that high-flux membrane improves the removal of moderate-sized molecules while other studies indicate no significant effect on them. OBJECTIVES This study aimed to investigate the dialysis efficacy of low-flux versus high-flux membranes in hemodialysis patients. PATIENT...
Urea kinetic modeling measures the delivered dose of hemodialysis and is used to monitor dialysis adequacy. Obtaining samples for adequacy calculations is a challenge for home hemodialysis (HHD) patients. Ideally, the urea reduction ratio (URR) should be measured at a typical dialysis session; therefore, for HHD patients test specimens should be drawn at home and transferred to a clinical labor...
Recent findings have shown that microbial nitrogen flow and digestible energy of diets are increased when urea is combined with a slow-release urea (SRU) in diets with a starch to acid detergent fibre ratio (S:F) 4:1. This affect is attributable to enhanced synchrony between ruminal N availability for microbial growth and carbohydrate degradation. To verify the magnitude of this effects on lamb...
according to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. the low value residual gold ions existed in acid leaching tail solution in mouteh gold mine in iran with fellow heavy metals as pollutants (fe2+, cu2+, and zn2+). preparation of nano gold particles is achieved by two steps: first, by addition of ammonia as separatio...
Brief exposure of central nervous connectives of the cockroach, Periplaneta americana, to 3 M-urea, a treatment known to increase the leak of cations across the blood-brain barrier system, caused a reduction in the resistance and potential difference (p.d.) across the perineurium, which forms the principal component of the barrier. There was also a reduction in the p.d. across the apical membra...
