Abstract The electrochemistry of catalase (CAT) was investigated at the interface between two immiscible electrolyte solutions (ITIES) as a step towards its detection. Electrochemistry ITIES offers advantages such non-redox detection biomolecules. electrochemical behaviour CAT ITIES, in micro-interface array format, displayed distinct cyclic voltammogram when aqueous phase pH lower than isoelec...

Background: Hubble-Bubble smoking is a common practice and spreading fast among young adults even in western countries. People think it less toxic than cigarette smoking.
 Aim: The aim of this study was to investigate the levels oxidative stress markers antioxidants blood (smokers compared controls as sign toxicity, since disease process caused by abnormal antioxidant capacity.
 Metho...

Reactive oxygen species (ROS) cause oxidative stress and aging. The catalase gene is a key component of the cellular antioxidant defense network. However, the molecular mechanisms that regulate catalase gene expression are poorly understood. In this study, we have identified a DNA replication-related element (DRE; 5'-TATCGATA) in the 5'-flanking region of the Drosophila catalase gene. Gel mobil...

Activated oxygen species have been demonstrated to be the important agents in oxygen toxicity by disrupting the structural and functional integrity of cells through lipid peroxidation events, DNA damage and protein inactivation. The biological consequences of free radical damage have long been hypothesized to be a causal agent in many aging-related diseases. Catalase (H2O2:H2O2 oxidoreductase; ...

An experiment was conducted to identify the biochemical defense enzymes, viz. catalase (CAT), peroxidase (POX), phenylalanine ammonia lyase (PAL) and total phenol responsible for resistance against A. solani in resistant (cv. H-88-78-1) susceptible (Punjab Chhuhara) cultivars of tomato after application Amistar 25 SC (azoxystrobin 0.1%) during 2015 crop season. Azoxystrobin applied their effica...

The goal of this study was to compare the effects kumquat extract and its chitosan nanoparticles on biochemical, histopathological, parasitological factors in mice infected with Toxoplasma gondii versus spiramycin control groups. A total 35 mice, 7 which were negative 28 group, used current study. All sacrificed at 45 day after inoculation. Blood samples collected. Then, sera Malondialdehyde (M...

Adaptation and defense responses are the consequences of exposure to drought stress in plants. Salicylic acid (SA) as a natural signaling molecule poses a significant impacts on various aspects of plant growth and development. This study investigates the effects of SA on carotenoids content, lipid peroxidation rate and antioxidant enzymes activities. A pot experiment was conducted using a facto...

Introduction and Aim: Idiopathic infertility accounts for at least 30% of all cases infertility, oxidative stress has been identified as a novel developing factor in idiopathic male infertility. Oxidative occurs when antioxidant defense mechanisms are outmatched by the creation reactive oxygen species (ROS). The purpose this research was to examine impact enzymatic antioxidants (catalase supero...

Objective: In this study, we plan to measure plasma Catalase (CAT), Antioxidant Activity (AOA) and Glutathione-S-Transferase (GST) levels to understand whether oxidative stress develops or not and whether or not the detoxification mechanism properly functions in children with Attention Deficit and Hyperactivity Disorder (ADHD) with unknown etiology and pathogenesis. Method and Results: Plasma C...
