Magnetohydrodynamic mixing was evaluated as an alternative to conventional high shear (HSM) in the preparation of carbomer hydrogels containing 1.22 wt% Carbopol® 980 NF. Neutralization dispersion (pH = 2.74) with triethanolamine (TEA) enabled adjust pH mixture and tune viscosity hydrogel. Using HSM, this approach limited 0.2 TEA 3.83) gel became too viscous recirculation flow dropped from 12 0...
background: induced abortion is not only a serious threat for women’s health, but also a controversial topic for its ethical and moral problems. we aimed to evaluate the relationship between neutralization techniques and attempting to commit abortion in married women with unintended pregnancy. methods: after in-depth interviews with some women who had attempted abortion, neutralization themes w...
Prothymosin alpha has previously been shown to be unfolded at neutral pH, thus belonging to a growing family of "natively unfolded" proteins. The structural properties and conformational stability of recombinant human prothymosin alpha were characterized at neutral and acidic pH by gel filtration, SAXS, circular dichroism, ANS fluorescence, (1)H NMR, and resistance to urea-induced unfolding. In...
pH-independent HIV entry into CD4-positive T cells via virus envelope fusion to the plasma membrane.
CD4 functions as the cell-surface receptor for human immunodeficiency virus (HIV); however, the mechanism of virus entry into susceptible cells is unknown. To explore this question we used a human T lymphoblastic cell line (VB) expressing high levels of surface CD4. Neutralization of endosomal compartments (pH greater than 6.4) with lysosomotropic agents did not effectively inhibit HIV nucleoca...
Staphylococcus epidermidis is the most frequent cause of peritonitis complicating continuous ambulatory peritoneal dialysis. We studied factors that might influence the growth of S. epidermidis in commercially available peritoneal dialysis solution (PDS). Test strains were inoculated into PDS and incubated overnight at 37°C. Samples were removed at appropriate intervals, bacterial counts were p...
<p><em>One of the causes environmental pollution is direct disposal wastewater into environment. Disposal both originating from domestic (household) and industrial activities water bodies can cause pollution. As one example, namely laundry waste that discharged directly bodies. The high phosphate content in causing an algae boom reduce dissolved oxygen so it will result death aquati...
