Bis(benzimidazole)amine-based copper complexes, with structural similarities to the active sites of Lytic Polysaccharide Monooxygenase enzymes (LPMOs), were tested for oxidative degradation cellulose. Spectroscopic characterization as well authentication one them, confirm a tetragonal coordination environment 3 nitrogen donors, thioether in axial positions. Aqueous cellulose was achieved CuII c...

This article reviews oxidative stress as one of the mechanisms impairing functions cells, organs, and tissues. Aging is associated with reductions in activities enzymes antioxidant system. Reactive oxygen species formed oxidant damage DNA, RNA, proteins, lipids, leading to cell apoptosis. Neurodegenerative changes can develop conditions mitochondrial dysfunction. A potential direction treatment...

Aberrant tissue repair and persistent inflammation following oxidant-mediated acute lung injury (ALI) can lead to the development and progression of various pulmonary diseases, but the mechanisms underlying these processes remain unclear. Hyperoxia is widely used in the treatment of pulmonary diseases, but the effects of this oxidant exposure in patients undergoing recovery from ALI are not cle...

The first suggestion that physical exercise results in free radical-mediated damage to tissues appeared in 1978, and the past three decades have resulted in a large growth of knowledge regarding exercise and oxidative stress. Although the sources of oxidant production during exercise continue to be debated, it is now well established that both resting and contracting skeletal muscles produce re...

Objectives: Liver is one of the most sensitive tissues to oxidant damage. Hence, the present study was conducted to compare the effects of Melissa officinalis (MO) extract and Atorvastatin on the activity of liver enzymes in rats. Materials and Methods: In this experimental study, 60 male Wistar rats were selected and allocated to six groups (n=10). The control group received a normal diet, sha...

A comprehensive study was conducted to optimise cage space allowance (CSA) for White Leghorn (WL) layers (65-80 weeks of age). For the purpose, a total 900 were housed in California colony cages an open sided poultry house at three different CSA (422, 563, 844 cm2/bird). Each studied with 20 replicates. The daily egg production (EP), feed intake (FI), efficiency (FE, FI/egg mass) and quality tr...

Objective(s): Cerebral ischemia/reperfusion causes complex pathological mechanisms that lead to brain tissue damage. Usnic acid is a lichen secondary metabolite that has many different biological properties including anti-inflammatory and anti-oxidant activities. Therefore, the objective of the current study was to investigate the neuroprotective effects of usnic acid ...

BACKGROUND Lecythis pisonis Cambess is commonly known as "castanha de sapucaia" in Brazil. Chemical composition studies revealed that this nut is an excellent source of anti-oxidant minerals and of essential lipids. OBJECTIVE The aim of the present study is to assess the anti-oxidant and anti-inflammatory effect of Lecythis pisonis Cambess on the brain tissue of Wistar rats. MATERIAL AND ME...

Thymoquinone is an active ingredient isolated from Nigella sativa and has been investigated for its anti-oxidant, anti-inflammatory and anticancer activities in both in vitro and in vivo models since its first extraction in 1960s. Its anti-oxidant/anti-inflammatory effect has been reported in various disease models, including encephalomyelitis, diabetes, asthma and carcinogenesis. Moreover, thy...
