Factors Defining Human Adipose Stem/Stromal Cell Immunomodulation in Vitro.

Human adipose tissue-derived stem/stromal cells (hASCs) are adult multipotent mesenchymal stem/stromal cells with immunomodulatory capacities. Here, we present up-to-date knowledge on the impact of different experimental and donor-related factors on hASC immunoregulatory functions in vitro. The experimental determinants include the immunological status of hASCs relative to target immune cells, contact vs.

Anti-Alzheimer Activity of Combinations of Cocoa with Vinpocetine or Other Nutraceuticals in Rat Model: Modulation of Wnt3/β-Catenin/GSK-3β/Nrf2/HO-1 and PERK/CHOP/Bcl-2 Pathways.

Alzheimer's disease (AD) is a devastating illness with limited therapeutic interventions. The aim of this study is to investigate the pathophysiological mechanisms underlying AD and explore the potential neuroprotective effects of cocoa, either alone or in combination with other nutraceuticals, in an animal model of aluminum-induced AD. Rats were divided into nine groups: control, aluminum chloride (AlCl) alone, AlCl with cocoa alone, AlCl with vinpocetine (VIN), AlCl with epigallocatechin-3-gallate (EGCG), AlCl with coenzyme Q10 (CoQ10), AlCl with wheatgrass (WG), AlCl with vitamin (Vit) B complex, and AlCl with a combination of Vit C, Vit E, and selenium (Se).

Potential role of PIM1 inhibition in the treatment of SARS-CoV-2 infection.

Background: SARS-CoV-2 infection involves disturbing multiple molecular pathways related to immunity and cellular functions. PIM1 is a serine/threonine-protein kinase found to be involved in the pathogenesis of several viral infections. One PIM1 substrate, Myc, was reported to interact with TMPRSS2, which is crucial for SARS-CoV-2 cell entry.

The role of PRDM1 gene polymorphism in the progression of hepatocellular carcinoma in Egyptian patients.

In Egypt, hepatocellular carcinoma (HCC) ranks as the second largest cause of cancer mortality. PRDM1 is a tumor suppressor gene essential for the differentiation and regulation activity of plasma cells and T cells. It plays a vital role in T cell exhaustion of chronic viral infection and HCC.

MiR-155 and MiR-665 Role as Potential Non-invasive Biomarkers for Hepatocellular Carcinoma in Egyptian Patients with Chronic Hepatitis C Virus Infection.

Background And Objectives: Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer associated death globally. Serum micro RNAs are full of potential as noninvasive biomarkers. Here, we aim to assess the performance of serum MicroRNA-155 and MicroRNA-665 as diagnostic biomarker for HCC comparing to AFP.

Effect of Sirtuin 1 inhibition on matrix metalloproteinase 2 and Forkhead box O3a expression in breast cancer cells.

Breast cancer is the most common invasive cancer in women worldwide. Sirtuin 1 (SIRT1) has recently been shown to have implications in regulating cancer cell growth and apoptosis. SIRT1 regulates Forkhead box O3a (FOXO3a) by both inhibiting FOXO3-induced apoptosis and potentiating the ability of FOXO3a to resist oxidative stress.

Prognostic Significance of Serum Vitamin D Levels in Egyptian Females with Breast Cancer.

Objective: To determine the frequency and prognostic significance of vitamin D deficiency in Egyptian women with breast cancer (BC). Methods: This prospective study included 50 women with primary invasive, non-metastatic BC. The serum level of 25-hydroxy vitamin D [25(OH)D was measured by ELISA at diagnosis, before any cancer treatment.

Assessment of the (rs1800795) and (rs1800796) Gene Polymorphisms in Egyptian Patients with Rheumatoid Arthritis.

Aim: This study aimed to investigate genotype and allele frequencies of -174 (rs1800795) and (rs1800796) promoter gene polymorphisms in Egyptian patients with rheumatoid arthritis (RA) in comparison to control group.

Methods: The study was conducted on 198 Egyptian subjects (99 RA patients and 99 healthy control). The promoter region of gene was amplified by PCR using DNAs from patients and the controls, and their PCR products were digested by suitable enzymes.

Ischemic heart diseases in Egypt: role of xanthine oxidase system and ischemia-modified albumin.

It is known that xanthine oxidoreductase contributes significantly to ischemia/reperfusion injury by generating reactive oxygen species. Ischemia-modified albumin (IMA) is a biomarker of acute myocardial ischemia with high sensitivity but moderate specificity. Our study aims to evaluate the xanthine oxidase (XO) system and the IMA level in the serum of patients with ischemic heart disease, and their correlation with traditional cardiac markers.
