Drought is one of the main abiotic stress factor that limits plant growth and development. effects on Borago officinalis L. (borage) plants in terms physiological antioxidant responses have been evaluated this study. In parallel with purpose, relative rate (RGR), leaf water content (RWC), osmotic potential, chlorophyll fluorescence (Fv/Fm), lipid peroxidation, hydrogen peroxide (H2O2) level, su...

Arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) are increasingly being used to enhance crop abiotic stress resistance. Common myrtle is an economically important essential oil-producing but knowledge about its drought resistance mechanisms the mitigation potential of AMF PGPR scant. Here, we investigated effects single dual (Funneliformis mosseae, Rhizophagus ...

BACKGROUND/AIM To evaluate salivary antioxidant defense markers, their correlation with salivary glucose, and glycemic status in type II diabetes mellitus (DM). MATERIALS AND METHODS The study included 53 diabetic patients and 40 healthy subjects. Salivary glucose, blood glucose, and uric acid (UA) were determined by specific enzymatic methods. Total antioxidant activity (AOA), glutathione (G...

Boron (B) is a non-metal micronutrient which is essential for plants growth and development. Formation of boron complex with cell wall matrix and phenolic compounds is a definite influence of boron in physiological process. It has been suggested that B-toxicity and deficiency may induce excess production of reactive oxygen species thereby promote defense responses by antioxidant enzymes or non-...

Neurodegenerative diseases like Parkinson’s disease (PD),Amyotrophic Lateral Sclerosis (ALS) and Schizophrenia are a group of illness with diverse clinical importance and etiologies. Oxidative stress in which production of highly reactive oxygen species (ROS) and reactive nitrogen species (RNS) overwhelms antioxidant defences, is a feature of many neurological diseases. Lycopene, the most poten...

objective(s):one cause of cigarette smoking is oxidative stress that may alter the cellular antioxidant defense system, induce apoptosis in lung tissue, inflammation and damage in liver, lung, and kidney. it has been shown that chinese green tea (cgt) (lung chen tea) has higher antioxidant property than black tea. in this paper, we will explore the preventive effect of cgt on cigarette smoke-in...

Oxidative stress has been implicated in the pathogenesis of many human diseases including Fanconi anemia (FA), a genetic disorder associated with BM failure and cancer. Here we show that major antioxidant defense genes are down-regulated in FA patients, and that gene down-regulation is selectively associated with increased oxidative DNA damage in the promoters of the antioxidant defense genes. ...

Calcium/calmodulin-dependent protein kinase (CCaMK) has been shown to play an important role in abscisic acid (ABA)-induced antioxidant defense and enhance the tolerance of plants to drought stress. However, its downstream molecular events are poorly understood. Here, we identify a NAC transcription factor, ZmNAC84, in maize (Zea mays), which physically interacts with ZmCCaMK in vitro and in vi...

Geriforte, a herbomineral preparation, feeding at 1 g% dose level for 4 weeks significantly increased catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities in liver of mice. In rats, in addition to these enzymes, the levels of reduced glutathione (GSH) were also significantly enhanced. However, only SOD in mice and, CAT and SOD activities in rat lung were signif...
