Intracellular Quantification of an Antibiotic Metal Complex in Single Cells of Using Cryo-X-ray Fluorescence Nanoimaging.

Bacterial resistance is a major public health challenge. In Gram-negative bacteria, the synergy between multidrug efflux pumps and outer membrane impermeability determines the intracellular concentration of antibiotics. Consequently, it also dictates antibiotic activity on their respective targets.

Disruption of epithelial barrier integrity via altered GILZ/c-Rel/RACK1 signaling in inflammatory bowel disease (IBD).

Background And Aim: Given the role of Receptor for Activated C Kinase 1 (RACK1) in both immune cell activation and in the maintenance of the intestinal epithelial barrier integrity, we investigated whether it was involved in inflammatory bowel disease (IBD).

Methods: RACK1 expression was analyzed in intestinal mucosal samples of healthy and IBD patients, in mice with chemically-induced colitis and in diseased in vitro 2D and 3D co-culture models by luciferase assay, RT-qPCR, Western blotting, immunofluorescence and immunohistochemistry. Based on our finding that glucocorticoid-induced leucine zipper (GILZ or tsc22d3) positively correlates with RACK1 expression in IBD patients, GILZ knock-out mice and cell silencing experiments were performed.

In Vitro and In Silico Biological Activities Investigation of Ethyl Acetate Extract of Schott Leaves Collected in Algeria.

This investigation aimed to assess the in vitro and in silico biological properties of the ethyl acetate (EtOAc) extract obtained from leaves of Schott collected in Algeria. The phytochemical screening data disclosed that flavonoids, tannins, coumarins, saponins, and anthocyanins were abundant. High levels of total phenolics, total flavonoids and flavonols (523.
