Efficacy of serum apelin and galectin-3 as potential predictors of mortality in severe COVID-19 patients.

Apelin is a cardioprotective biomarker while galectin-3 is a pro-inflammatory and profibrotic biomarker. Endothelial dysfunction, hyperinflammation, and pulmonary fibrosis are key mechanisms that contribute to the development of adverse outcomes in Coronavirus disease 2019 (COVID-19) infection. This study aims to analyze the prognostic value of serum apelin and galectin-3 levels to early predict patients at high risk of mortality in patients hospitalized for severe COVID-19 pneumonia.

The Effect of Adipose-Derived Stromal Vascular Fraction Cells to Abdominal Wall Fascia Defects in Rats: An Experimental Study.

Objective: Various synthetic and biological meshes have been developed to reduce recurrence and complications in ventral incisional hernia repairs. Adipose tissue is a rich reserve for mesenchymal stromal cells. In the present study we aimed to examine the effects of adipose-derived mesenchymal stromal cells (AD-MSCs) on abdominal incisional hernia repairs in rats.

The probable role of insulin resistance and SIRT1 proteins in the Alzheimer's disease.

Objective: Recent evidence suggests that insulin resistance may play an important role in the pathogenesis of Alzheimer's disease (AD). In this study, the probable role of insulin resistance in the pathogenesis of AD was investigated in patients with Type 2 Diabetes Mellitus (T2DM).

Methods: Serum amyloid beta (Aβ) (1-42), insulin like growth factor-1 (IGF-1), sirtuin1 (SIRT1) and leptin protein levels were measured in serum samples of control (n = 26), probable AD (n = 26), and probable AD+T2DM patients (n = 12) using ELISA method.

The effects of N-acetylcysteine and epigallocatechin-3-gallate on liver tissue protein oxidation and antioxidant enzyme levels after the exposure to radiofrequency radiation.

Purpose: The widespread and sustained use of mobile and cordless phones causes unprecedented increase of radiofrequency radiation (RFR). The aim of this experimental study was to investigate the effect of 900 MHz Global System for Mobile Communications (GSM)-modulated RFR (average whole body Specific Absorption Rate (SAR) of 0.4 W/kg, 10 or 20 min daily for consecutive 7 days) to the liver tissue of guinea pigs and the protective effects of antioxidant treatments.

Thyroid hormones-mediated effects of insulin on antioxidant enzymes from diabetic rat hearts.

Free radicals, oxidative stress, and antioxidants have become commonly used terms in modern discussion of disease mechanisms. Accumulation of evidence suggests that toxic oxygen-derived reactive free radicals (superoxide, peroxide and hydroxyl radicals) play a crucial role in etiology of diabetes and its complication. Thus, it was aimed to determine the role of thyroid hormones in reversal of antioxidatant enzyme activities and lipid peroxidation alterations observed in experimentally induced diabetic rat hearts.
