Therapeutic Impact of Aerobic Exercise on Adolescents with Obesity and Its Association with Expression of miRNAs and Cytokines: A Clinical Approach.

: MicroRNAs are short noncoding RNAs that play an essential role in controlling gene expression at the posttranscriptional level. They can serve as biomarkers in the management of obesity. Circulating miRNAs levels change with exercise, impacting various physiological and biological systems, including structural and functional changes.

Antiobesity, antioxidant and hepatoprotective effects of Diallyl trisulphide (DATS) alone or in combination with Orlistat on HFD induced obese rats.

The increasing rate of obesity in the past years has become a worldwide concern and it causes many diseases. Even though, Orlistat, a synthetic anti-obesity drug approved by FDA, it causes severe side effects. DATS, a natural product from garlic have gained attention in many biological activities.

Lycopene supplementation prevents reactive oxygen species mediated apoptosis in Sertoli cells of adult albino rats exposed to polychlorinated biphenyls.

Sertoli cell proliferation is attenuated before attaining puberty and the number is fixed in adult testes. Sertoli cells determine both testis size and daily sperm production by providing physical and metabolic support to spermatogenic cells. Polychlorinated biphenyls (PCBs) exposure disrupts functions of Sertoli cells causing infertility with decreased sperm count.

Polychlorinated biphenyls-induced oxidative stress on rat hippocampus: a neuroprotective role of quercetin.

Present study is aimed to evaluate the ameliorative role of quercetin on PCBs-induced oxidative stress in hippocampus of Wistar rats. Group I rats received vehicle (corn oil) intraperitoneally (i.p); Group II received quercetin 50 mg/kg bwt/day (gavage); Group III received PCB 2 mg/kg bwt/day (i.

Protective role of quercetin on PCBs-induced oxidative stress and apoptosis in hippocampus of adult rats.

Polychlorinated biphenyls (PCBs) exposure produces neurodegeneration and induces oxidative stress. Neuroprotective role of quercetin, on PCBs induced apoptosis in hippocampus has not yet been studied. The present study is focused to see whether quercetin supplementation precludes against PCBs induced oxidative stress and hippocampal apoptosis.

Polychlorinated biphenyl (PCBs)-induced oxidative stress plays a critical role on cerebellar dopaminergic receptor expression: ameliorative role of quercetin.

Polychlorinated biphenyls (PCBs) exposure produces profound damage to the developing as well as adult central nervous system. Locomotor activities which are closely linked to dopaminergic neurotransmission are often impaired in PCBs toxicity. Targeting PCBs-induced oxidative stress using natural antioxidants is an attractive approach.

Effect of melatonin on PCB (Aroclor 1254) induced neuronal damage and changes in Cu/Zn superoxide dismutase and glutathione peroxidase-4 mRNA expression in cerebral cortex, cerebellum and hippocampus of adult rats.

Polychlorinated biphenyls (PCBs) are one of the environmental toxicants and neurotoxic compounds which induce the production of free radicals leading to oxidative stress. Free radicals represent a class of biologically generated species that pose a potential threat to neuronal survival. Cu/Zn superoxide dismutase (SOD) and glutathione peroxidase-4 (GPx-4) are the key cellular antioxidant enzymes by which neurons and other cells detoxify free radicals and protect themselves from damage.

Oxidative stress alters creatine kinase system in serum and brain regions of polychlorinated biphenyl (Aroclor 1254)-exposed rats: protective role of melatonin.

Polychlorinated biphenyls are one of the environmental toxicants and neurotoxic compounds which induce the production of free radicals. Creatine kinase plays a key role in energy metabolism of nervous tissue and might be one of the targets for reactive oxygen species. Melatonin, an indoleamine, plays an important role in neurodegenerative diseases as an antioxidant and neuroprotector.

Studies on the protective role of lycopene against polychlorinated biphenyls (Aroclor 1254)-induced changes in StAR protein and cytochrome P450 scc enzyme expression on Leydig cells of adult rats.

Polychlorinated biphenyls (PCBs) are ubiquitous and persistent environmental contaminants that disturb normal endocrine functions, including gonadal functions in humans and mammals. PCBs (Aroclor 1254) - induced toxic manifestations are associated with the production of free radicals. Lycopene belongs to the group of natural carotenoids, which are found in many fruits, vegetables and other green plants.

Protective role of melatonin on PCB (Aroclor 1,254) induced oxidative stress and changes in acetylcholine esterase and membrane bound ATPases in cerebellum, cerebral cortex and hippocampus of adult rat brain.

Polychlorinated biphenyls (PCBs) are one of the environmental toxicants and neurotoxic compounds which induce the production of free radicals leading to oxidative stress. Membrane proteins that control ion gradients across organellar and plasma membranes appear to be particularly susceptible to oxidation induced changes. Melatonin plays an important role in neurodegenerative diseases as an antioxidant and neuroprotector.

Modulation of antioxidant defense system by the environmental fungicide carbendazim in Leydig cells of rats.

Carbendazim (methyl-2-benzimidazole carbamate, MBC) a metabolite of benomyl is one of the most widespread environmental contaminant of major concern to human and animal reproductive health. The present investigation was undertaken to study the impact of carbendazim exposure on Leydig cell functions. Adult albino male rats of the Wistar strain were administered with carbendazim (25 mg/(kg (body weight)/day)) orally for 48 days.

PCB (Aroclor 1254) enhances oxidative damage in rat brain regions: protective role of ascorbic acid.

PCBs are one of the environmental toxicants and neurotoxic compounds which induce the production of free radicals leading to oxidative stress. Oxidative stress is a contributing factor to alteration caused in neurodegenerative processes. The ability of Vitamin C to retard oxidative processes has been recognized for many years.

Role of alpha-tocopherol on antioxidant status in liver, lung and kidney of PCB exposed male albino rats.

Polychlorinated biphenyls (PCB) are widespread, lipophilic environmental pollutants which have been identified as contaminants in almost every component of the global ecosystem including fish, wildlife, and human adipose tissue, breast milk, and serum. Several studies have shown that PCBs can cause oxidative damage to biomolecules, in the form of lipid peroxidation, modulation of antioxidant enzymes, and oxidative stress. In the present study, we have sought to investigate the effects of alpha-tocopherol (vitamin E) on antioxidant status of PCB-induced toxicity in male Wistar rats.

Chemoprevention of rat prostate carcinogenesis by diallyl disulfide, an organosulfur compound of garlic.

Diallyl disulfide (DADS), an important component of garlic (Allium sativam) has been demonstrated to exert a potential chemopreventive activity against human cancers. DADS inhibits proliferation of both androgen dependent and independent prostate cancer cells in vitro. However there is no report available on the role of DADS on prostate cancer initiation in in vivo model.

Ovariectomy induces oxidative stress and impairs bone antioxidant system in adult rats.

Background: There is increasing evidence suggesting the role of free radicals in bone resorption and bone loss. Ovariectomized rats have been used as the animal model for the study of osteoporosis. Oxidative stress due to reactive oxygen species (ROS) can cause oxidative damage to cells.
