Eminent Antimicrobial Peptide Resistance in : A Novel Advantage of Intrinsically Uncoupled Energetics.

Relative to several model bacteria, the ethanologenic bacterium is shown here to have elevated resistance to exogenous antimicrobial peptides (AMPs)- with regard to both peptide bulk concentration in the medium and the numbers of peptide molecules per cell. By monitoring the integration of AMPs in the bacterial cell membrane and observing the resulting effect on membrane energy coupling, it is concluded that the membranotropic effects of the tested AMPs in and in are comparable. The advantage of over apparently results from its uncoupled mode of energy metabolism that, in contrast to , does not rely on oxidative phosphorylation, and hence, is less vulnerable to the disruption of its energy-coupling membrane by AMPs.

The effect of curcuma longa extract and significance of mordant as an alternative for eosin in H and E: A comparative study.

Background And Aim: Hematoxylin and Eosin (H and E) staining is a common and routine staining method used in Histopathology. In origin, Hematoxylin is natural and Eosin is a synthetic dye. Synthetic dyes are widely accepted due to its staining efficiency.

Comparative Evaluation of Existing and Rationally Designed Novel Antimicrobial Peptides for Treatment of Skin and Soft Tissue Infections.

Skin and soft tissue infections (SSTIs) and acne are among the most common skin conditions in primary care. SSTIs caused by ESKAPE pathogens (, , , , , and sp.) can range in severity, and treating them is becoming increasingly challenging due to the growing number of antibiotic-resistant pathogens.

Preparation of Chiral Enantioenriched Densely Substituted Cyclopropyl Azoles, Amines, and Ethers via Formal S2' Substitution of Bromocylopropanes.

Enantiomerically enriched cyclopropyl ethers, amines, and cyclopropylazole derivatives possessing three stereogenic carbon atoms in a small cycle are obtained via the diastereoselective, formal nucleophilic substitution of chiral, non-racemic bromocyclopropanes. The key feature of this methodology is the utilization of the chiral center of the cyclopropene intermediate, which governs the configuration of the two adjacent stereocenters that are successively installed via 1,4-addition/epimerization sequence.

Cellulose-Based Hydrogels and Aerogels Embedded with Silver Nanoparticles: Preparation and Characterization.

The paper presents the preparation and characterization of novel composite materials based on microcrystalline cellulose (MCC) with silver nanoparticles (Ag NPs) in powder and gel forms. We use a promising synthetic conception to form the novel composite biomaterials. At first MCC was modified with colloidal solution of Ag NPs in isopropyl alcohol prepared via metal vapor synthesis.
