3.1.1. Antibacterial Activity Saponins present detergent properties by destroying membrane lipids and, for this reason, they can make the bacterial cell membranes permeable facilitating the influx of molecules through the bacterial wall, such as antibiotics [43–45]. On the other hand, ...
When a Bt crystal reaches the insect's gut, it is solubilized to release one or more protoxins. These protoxins are then proteolyzed and activated by midgut proteases and the toxins can bind to and disrupt cell membranes. The binding and insertion of toxins in the ...

The primary role of UPR is to try to drive back the system to the former or a new homeostatic state by self-eating dependent autophagy, while excessive level of ER stress results in apoptotic cell death. Our study focuses on the role of PERK- and IRE-1-induced arms of UPR in life-or...
In general, it supplies the skin and mucous membranes of the head and nose at the front. It supplies the skin of the face above the level of the orbit, but extending down to the tip of the nose only on the anterior aspect. It does not supply the lateral aspect of the nose. These ...
(Thermo Scientific), equal amounts of proteins were separated by SDS-PAGE gel electrophoresis and transferred to polyvinylidene difluoride membranes (Merck Millipore). Membranes were blocked in 5% BSA (Sigma) at room temperature for 1 h, followed by incubation with primary antibodies against GAPDH (...
Furthermore, other research on newly developed PLA fibers combined the polymer with curcumin to produce a membrane by RJS for wound healing applications. The authors demonstrated that PLA / curcumin membranes are cytocompatible with mouse embryonic fibroblasts [107]. It is worth mentioning the work ...
The cell densities of the different types of A. ferrooxidans in the above system were detected to be about 6.0 × 106 cell·mL−1. The pH of the system was buffered to 3.0 using 1:1 H2SO4, then the EPS content was determined in supernatant (filtered through 0.22 membranes). All ...

Our results indicate that the compounds in the range of used concentrations do not have a toxic effect on red blood cells. 2.4. Fluorescence Spectroscopy Fluorescence spectroscopy was used to study the effect of tested compounds on red blood cell membranes (RBCM). Three fluorescent probes were ...
