BACKGROUND Several studies have been carried out to evaluate the effects of dialysis on pulmonary function tests (PFT). Dialysis procedure may reduce lung volumes and capacities or cause hypoxia; however, to the best of our knowledge, there is no previous study evaluating the effects of membrane type (high flux vs. low flux) on PFT in these patients. The aim of this study was the evaluation of ...

Amyloidosis is an important cause of mortality and morbidity in patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD). In this study, depending on the idea that the clearance of middle and high molecular weight toxins could be improved, we aimed to investigate the effect of high-flux dialyzer on clearance of beta-2 microglobulin (beta2-MG) and calcium (Ca) phosphorus (P) met...

BACKGROUND Several studies have been carried out to evaluate the effects of dialysis on O2 saturation. While the dialysis procedure may lead to hypoxia under different circumstances, there are few studies available on the effects of membrane type on O2 saturation in these patients. OBJECTIVES This study was to appraise the effects of high and low flux membrane on pulse oxymetery in dialysis p...

To understand the regional impact of the atmospheric aerosols on the surface energy and water cycle in the southern Sierra Nevada characterized by extreme variations in terrain elevation, the authors examine the aerosol radiative forcing on surface insolation and snowmelt for the spring of 1998 in a regional climate model experiment. With a prescribed aerosol optical thickness of 0.2, it is fou...

Experiments were conducted to determine whether the nitrate flux to the leaves or the nitrate content of the leaves regulated the nitrate reductase activity (NRA) in leaves of intact maize (Zea mays L.) seedlings having low water potentials (psi(w)) when other environmental and endogenous factors were constant. In seedlings that were desiccated slowly, the nitrate flux, leaf nitrate content, an...
