Binary mixtures of C(20)BAS and POPC membranes were studied by solid-state (2)H NMR spectroscopy and small angle x-ray scattering (SAXS) over a wide range of concentrations and at different temperatures. Three specifically deuterated C(20)BAS derivatives--[1',1',20',20'-(2)H(4)]C(20)BAS, [2',2',19',19'-(2)H(4)]C(20)BAS, and [10',11'-(2)H(2)]C(20)BAS--combined with protiated 1-palmitoyl-2-oleoyl...

In this study, polyethersulfone based nanofiltration membranes were modified by air plasma generated through dielectric barrier discharge to increase the membrane hydrophilicity aiming to improve the separation and antifouling characteristics. The effect of plasma time on the physico-chemical and separation properties of membrane was investigated. The PES nanofiltration membranes were fabricate...

introduction: perepubertal varicocele can result in hypotrophy of testes, sperm damage and decrease the function of leydig cells in future. pathophysiology of varicocele is unclear. increased reactive oxygen species (ros) is a major theory. there are many controversies in treatment of pediatric varicocele. flaxseed (fs) is the richest source of lignans with antioxidant properties. the aim of th...

Acetamiprid (ACP) belonging to the neonicotinoid family used against wide array of pests in agriculture and domestic purposes. In this study, we evaluated the attenuating effects of ethanolic extract of Mangifera indica leaves (EEMI) in averting reproductive toxicity caused by ACP in male guinea pigs. Thirty male guinea pigs were randomly assigned to five treatment groups (n = 6). Grou...

this experiment was conducted to evaluate the addition of seminal plasma to coated spermatozoa after 72 h. semen was collected from four taleshi rams by artificial vagina. to prepare coated spermatozoa, semen was collected in tube containing tris-fructose-15% egg yolk. after initial evaluation, the samples were mixed and centrifuged. after removal of supernatant and dilution, samples were divid...

We investigated relationship of arsenicosis symptoms with total blood arsenic (BAs) and serum albumin (SAlb) of residents in the Mekong River basin of Cambodia. We found that arsenicosis patients had significantly higher BAs and lower SAlb than asymptomatic villagers (Mann-Whitney U test, p<0.01). Arsenicosis symptoms were found to be 76.4% (1.764 times) more likely to develop among individuals...
