Single-nucleus and spatial landscape of the sub-ventricular zone in human glioblastoma.

The sub-ventricular zone (SVZ) is the most well-characterized neurogenic area in the mammalian brain. We previously showed that in 65% of patients with glioblastoma (GBM), the SVZ is a reservoir of cancer stem-like cells that contribute to treatment resistance and the emergence of recurrence. Here, we build a single-nucleus RNA-sequencing-based microenvironment landscape of the tumor mass and the SVZ of 15 patients and two histologically normal SVZ samples as controls.

Muscle inflammation is regulated by NF-κB from multiple cells to control distinct states of wasting in cancer cachexia.

Although cancer cachexia is classically characterized as a systemic inflammatory disorder, emerging evidence indicates that weight loss also associates with local tissue inflammation. We queried the regulation of this inflammation and its causality to cachexia by exploring skeletal muscle, whose atrophy strongly associates with poor outcomes. Using multiple mouse models and patient samples, we show that cachectic muscle is marked by enhanced innate immunity.

Role of macrophages in regression of myocardial fibrosis following alleviation of left ventricular pressure overload.

Sustained hemodynamic pressure overload (PO) produced by murine transverse aortic constriction (TAC) causes myocardial fibrosis; removal of TAC (unTAC) returns left ventricle (LV) hemodynamic load to normal and results in significant, but incomplete regression of myocardial fibrosis. However, the cellular mechanisms that result in these outcomes have not been defined. The objective was to determine temporal changes in myocardial macrophage phenotype in TAC and unTAC and determine whether macrophage depletion alters collagen degradation after unTAC.

Interaction of human immunodeficiency virus-1 and human immunodeficiency virus-2 capsid amino acid variants with human tripartite motif 5α protein SPRY domain and its association with pathogenesis.

Purpose: The sequence variation of human immunodeficiency virus (HIV) capsid region may influence and alter the susceptibility to human tripartite motif 5α protein (huTRIM5α).

Materials And Methods: Molecular docking was carried out with huTRIM5α SPRY domain by the use of ClusPro and Hex docking program for HIV-1 and HIV-2 capsid sequences.

Results: The sequence analysis on HIV-1 and HIV-2 capsid gag gene identified 35 (19.

Molecular Docking Studies of Potential Inhibition of the Alcohol Dehydrogenase Enzyme by Phyllanthin, Hypophyllanthin and Gallic Acid.

A review of literature shows certain phytochemicals, phyllanthin, hypophyllanthin and gallic acid have beneficial effects in experimental animals for improving liver metabolism in alcoholic liver disease. We investigated the ability of these chemicals to exhibit the inhibitory effect on the enzyme, alcohol dehydrogenase active site. The software used were CASTp, AutoDock and Molinspiration in Windows platform.

Design of peptide epitope from the neuraminidase protein of influenza A and influenza B towards short peptide vaccine development.

Influenza viruses A and B are important human respiratory pathogens causing seasonal, endemic and pandemic infections in several parts of the globe with high morbidity and considerable mortality. The current inactivated and live attenuated vaccines are not effective. Therefore, it is of interest to design universal influenza virus vaccines with high efficacy.

Clinical Evaluation of a Polyherbal Nutritional Supplement in Dyslipidemic Volunteers.

Ten important plant parts routinely used in South Indian ethnic food preparation as spices and condiments were investigated for their potential antidyslipidemic properties. The aim of the study was to characterize the biochemical properties of the polyherbal formulation (nutritional supplement) and evaluate its use to control dyslipidemia in patients. Phytochemical evaluation, in vitro α-amylase inhibitory assay, and high performance thin layer chromatography (HPTLC) fingerprinting were carried out with alcoholic extracts of all 10 individual plants and with the nutritional supplement.

Natural Inhibitors of HMG-CoA Reductase-An Insilico Approach Through Molecular Docking and Simulation Studies.

Plant products have always been considered for many important metabolic disorders due to its abundant medicinal properties. Alarming adverse effects of overuse of statins has been reported for patients with dyslipidemia. This study was aimed to identify compounds with potent anti-dyslipidemic property from selected plants and analyze them for their efficiency in binding with HMG-CoA reductase, a key enzyme in lipid metabolism.

Hepatocurative activity of biosynthesized silver nanoparticles fabricated using Andrographis paniculata.

The current investigation was aimed to determine the hepatocurative role of silver nanoparticles (AgNPs) synthesized rapidly using Andrographis paniculata. The nanoparticles fabricated at varying temperatures were characterized by UV-visible spectroscopy (UV-vis), transmission electron microscopy (TEM), fourier transform infra-red spectroscopy (FTIR), energy dispersive X-ray (EDX) and inductively coupled plasma optical emission spectroscopy (ICP-OES) alongside zeta potential measurement. UV-vis spectroscopic readings indicated a prominent peak at 423 nm.
