results the mean kt/v was 1.27 ± 0.28 in high-flux and 1.10 ± 0.32 in low-flux membrane which, these differences were statistically significant (p = 0.017). the mean of urr was 0.65 ± 0.09 in high-flux and 0.61 ± 0.14 in low-flux membrane, which these differences were not statistically significant (p = 0.221). patients and methods forty hemodialysis patients participated in this cross-over clin...

Background: The risk of developing tuberculosis is high among chronic hemodialysis patients. The tuberculin skin test (TST) has been in use for diagnosing latent TB, but few data are available on TST in hemodialysis patients. Objective: This study was done to identify the TST reactivity and frequency of booster effect in serial TST among hemodialysis patients. Methods: A total of 100 patients i...

BACKGROUND While endovascular stent placement is the standard of care in most percutaneous coronary and peripheral artery intervention, its role in the salvage of thrombosed and stenotic hemodialysis access remains controversial. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS We compared the effects of stent versus angioplasty on primary patency rates in the treatment of stenotic arterioveno...

abstract to study the effects of different levels of n, mn and zn on yield and quality of pomegranate fruit a factorial experiment based on complete randomized block design with 18 treatments and three replications was conducted in behshahr city, mazandaran province, in 2009.investigated treatments were include: nitrogen, manganese, zinc. fertilizer source for nitrogen was urea and three rates ...

The aim of this study was to investigate the effect different forms Lentilactobacillus buchneri on in vitro methane production, fermentation characteristics, nutritional quality, and aerobic stability corn silage treated with or without urea. following treatments were applied prior ensiling: (1) no urea treatment LB; (2) treatment+freeze dried (3) treatment+preactivated (4) treatment+no (5) (6)...

BACKGROUND AND OBJECTIVE Low molecular weight heparins (LMWHs) are small enough to pass large pore dialysis membranes. Removal of LMWH if injected before the start of the session is possible during high-flux dialysis and hemodiafiltration. The aim of this study was to determine the optimal mode (place and time) of tinzaparin administration during postdilution hemodiafiltration. STUDY DESIGN, ...

Anabaena oryzae ARM 570 was examined for its growth (chlorophyll and protein), heterocyst frequency, nitrogenase (acetylene reduction) activity, ammonia excretion, and glutamine synthetase and nitrate reductase in response to two levels of urea-N vis-à-vis N2-N. Growth of cyanobacterium increased with duration of incubation. Reduction in heterocyst frequency (40%) was observed at 30 ppm of urea...

The effect of intravenous urea was discussed and the fall in pressure after the administration of the conventional dosage compared with that following 5 g. A similar reduction in pressure occurred with the smaller dose but was of shorter duration. Reductions in intracranial pressure following the use of Mannitol and Frusemide were also compared with the results seen with urea. Difficulties aros...
