In order to reduce the infection rate of major respiratory diseases, it is crucial development masks with antibacterial functions. This paper describes an electrospun polyvinyl alcohol (PVA) fibrous membranes loaded drugs. The concentration artemisinin (ART)/chloroquine phosphate (CQP) in PVA solution and process parameters were investigated. Meanwhile, physical properties effect, filtration pe...

Pasteurella multocida (P. multocida), A Gram-negative facultative anaerobic bacterium, is a causative animal pathogen in porcine atrophic rhinitis and avian fowl cholera. The outer membrane of Gram-negative bacteria contains of many different protein in very high copy numbers. One of the major outer membrane, the H proteins have functional as high immunogenicity and antigenicity. In this study ...

High-performance and cost-effective laser protection system is of crucial importance for the rapid advance of lasers in military and civilian fields leading to severe damages of human eyes and sensitive optical devices. However, it is crucially hindered by the angle-dependent protective effect and the complex preparation process. Here we demonstrate that angle-independence, good processibility,...

background: curcumin has shown to affect sperm motility and function in vitro and fertility in vivo. the molecular mechanism(s) by which curcumin affects sperm motility has not been delineated. since modulation of intracellular ph (phi) and plasma membrane polarization is involved in sperm motility, the present study was conducted to investigate the effect of curcumin on these sperm (human and ...

The outer membrane is a continuous structure on the surface of Gram-negative bacteria and has particular significance as one of the potential targets for protective immunity. Recent studies have focused attention on the outer membrane proteins (OMPs) suggesting the existence of protective immunogenic components in Salmonella. Outer membrane protein (OMPs) has been reported to be immunogens for ...

The effect of Triton X-100, Na cholate and Tween 80 on the solubilization of integral membrane proteins in intact cells, spheroplasts and inner-membrane fragments of Salmonella typhimurium was studied. The detergents were used in various concentrations (1.6 to 64 mM) and cytochromes b and d were used as marker to monitor the solubilization of membrane-bound proteins. Results showed that no inne...

Outer membrane vesicles (OMVs), secreted from Gram-negative bacteria, are spherical nanometer-sized proteolipids enriched with outer membrane proteins. OMVs, also known as extracellular vesicles, have gained interests for use as nonliving complex vaccines and have been examined for immune-stimulating effects. However, the detailed mechanism on how OMVs elicit the vaccination effect has not been...

The mechanistic basis for cation amelioration of Al rhizotoxicity in soybean was investigated through a series of studies comparing protective effects of Ca and Mg against Al inhibition of root elongation in a background 0.8 mM CaSO4 solution (pH 4.3). A modified Gouy-Chapman-Stern model was used to evaluate the effect of cations on electrical potential and Al3+ activity at root plasma membrane...

The obese Zucker rat is a valuable model for studying kidney disease associated with obesity and diabetes. Previous studies have shown that substitution of animal protein with soy ameliorates the progression of renal disease. To explore the participation of nitric oxide (NO) and caveolin-1 in this protective effect, we evaluated proteinuria, creatinine clearance, renal structural lesions, nitri...
