During the course of our screening program for low molecular natural products with their ability to potentiate and/or mimic neurotrophic effect of NGF, a novel fungal metabolite, phenylacetic acid hydrazide derivative NG-061 was isolated from the fermentation broth of Penicillium minioluteum F-4627. NG-061 enhanced and mimicked neurotrophic effect of NGF on neurite outgrowth in a rat pheochromocytoma cell line PC12.

Background: Strain Cyp38S was isolated as an endophyte from the plant Cyperus alternifolius, collected along the banks of the River Nile in 2019. Preliminary analysis tentatively identified Cyp38S as belonging to the genus Pseudocitrobacter.
Methods: The preliminary identification of Cyp38S was performed using the VITEK2 identification system, MALDI-TOF-MS, and 16S rRNA gene sequencing.
Our research on the expression and characterization of exosomal miRNAs in buffalo milk, particularly in the context of healthy, sub-clinical mastitis and pasteurized milk, is a novel contribution to the field. We are the first to investigate the expressions of miRNAs and the characterization of exosomes in boiled and pasteurized milk. This study is based on clinical signs and CMT, where twenty buffalo milk samples were divided into normal and sub-clinical mastitis and a third group of ten commercial pasteurized milk.

Erythroderma is a severe and heterogeneous inflammatory skin condition with little guidance on the approach to management in cases of unknown etiology. To guide therapeutic selection, we sought to create an immunophenotyping platform able to identify aberrant cell populations and cytokines in subtypes of erythroderma. We performed high-parameter flow cytometry on peripheral blood mononuclear cells (PBMCs) and whole blood of a patient with refractory idiopathic erythroderma, erythrodermic patients with Sézary syndrome and pityriasis rubra pilaris, and healthy controls.

The Eurasian avian-like (EA) H1N1 swine influenza virus (SIV) possesses the capacity to instigate the next influenza pandemic, owing to its heightened affinity for the human-type α-2,6 sialic acid (SA) receptor. Nevertheless, the molecular mechanisms underlying the switch in receptor binding preferences of EA H1N1 SIV remain elusive. In this study, we conduct a comprehensive genome-wide CRISPR/Cas9 knockout screen utilizing EA H1N1 SIV in porcine kidney cells.

TP53 is normally a tumor suppressor. However, it is mutated in at least 50% of human cancers. Usually, we assume that mutation of the TP53 is associated with loss of sensitivity to various drugs as in most cases wild type (WT) TP53 activity is lost.
