Severity of oxidative stress as a hallmark in COVID-19 patients.

Introduction: Understanding the mechanisms and identifying effective treatments for the COVID-19 outbreak are imperative. Therefore, this study aimed to assess the antioxidant status and oxidative stress parameters as potential pivotal mechanisms in asymptomatic, non-severe, and severe COVID-19 patients.

Methods: This study is a case-control study that was performed on patients referred to the Persian Gulf Martyrs Hospital of Bushehr University of Medical Sciences, Bushehr, Iran, from May 2021 to September 2021.

Crosstalk between autophagy and insulin resistance: evidence from different tissues.

Insulin is a critical hormone that promotes energy storage in various tissues, as well as anabolic functions. Insulin resistance significantly reduces these responses, resulting in pathological conditions, such as obesity and type 2 diabetes mellitus (T2DM). The management of insulin resistance requires better knowledge of its pathophysiological mechanisms to prevent secondary complications, such as cardiovascular diseases (CVDs).

and Molecular Docking Analysis of Quercetin as an Anti-inflammatory and Antioxidant.

Introduction: Quercetin (3,3',4',5,7-pentahydroxyflavone) is a dietary flavonoid with good antioxidant and anti-inflammatory properties.

Aims: The present study aims to determine these effects in peripheral blood mononuclear cells (PBMCs) evoked by lipopolysaccharides (LPS).

Methods: The mRNA expression and protein secretion of inflammatory mediators were evaluated by enzyme- linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (PCR), respectively.

A comparative study on the effect of blood collection tubes on stress oxidative markers.

Oxidative stress has a major role in disease pathogenesis. However, limited studies have investigated the effect of various sample collection tubes on oxidative biomarkers. The present study aimed to evaluate the effect of different collection tubes on the variation of malondialdehyde (MDA), nitric oxide (NO), total thiol (t-SH), and ferric reducing ability of plasma (FRAP) levels.

Iron Chelator or Iron Supplement Consumption in COVID-19? The Role of Iron with Severity Infection.

Iron is a trace element that is used to replicate the virus and has a role in the vital functions of the body and the host's innate immune system. The mechanism of iron in COVID-19 severity is still not well understood. The aim of this study was to evaluate the association of the iron with COVID-19 severity.

The effects of malvidin on oxidative stress parameters and inflammatory cytokines in LPS-induced human THP-1 cells.

Malvidin is an anthocyanin which is involved in inhibiting inflammatory-related mediators in inflammatory diseases; however, its mechanism of action in THP-1 cells is not yet known. THP-1 is a human monocytic cell line that is derived from patients with acute monocytic leukemia. The present study aimed to investigate the effect of malvidin on inflammatory responses and oxidative stress in lipopolysaccharide (LPS)-induced THP-1 cells.
