Abbreviations: 2,4-D: 2,4-dichlorophenoxyacetic acid ABA: abscisic acid ABI3: ABI gene family member 3 ANP1: Arabidopsis NPK1-like protein kinase AP: ascorbate peroxidase AOX: alternative oxidase DNA: deoxyribonucleic acid Fe-EDTA: ferric ethylenediaminetetraacetic acid M: molar concentration MAPK: mitogen-activated protein kinase NO: Nitric oxide PGRs: plant growth regulators ROS: reactive oxy...

The purpose of this study was to determine whether superoxide anion is produced endogenously in the rat aortic adventitia and whether sufficient superoxide anion is produced to interfere with the response of the rat aorta to nitric oxide. Relaxation was measured in rings of the rat thoracic aorta, which were oriented so that the adventitial or luminal surface could be preferentially exposed to ...

Doxorubicin (DOX) induces oxidative stress leading to cardiovascular abnormalities. Green tea extract (GTE) is reported to possess antioxidant activity mainly by means of its polyphenolic constituent, catechins. Our study was aimed to find out the effect of GTE (100 mg/kg / day p.o. for 28 days) on DOX induced (3 mg/kg, IP on days 1, 7, 14, 21, 28) cardiovascular abnormalities in rat heart. DOX...

Present study deals with the hepatoprotective activity of polyherbal formulation Hepatoplus (HP) as an oral supplement to the INH and RIF induced hepatitis in experimental rats. Rats treated with INH and RIF show abnormal liver function with significant increase in serum transaminases, bilirubin and clotting time (CT) and significant decrease in total protein and Albumin, which is brings to nea...

Regulation of the peroxisome proliferator-activated receptor-γ (PPAR-γ) gene plays an important role in controlling the metabolism of lipids and inflammatory processes. Therefore, it can be associated with the pathogenesis of metabolic syndrome (MetS). The purpose of this study was to determine the expression of this gene in peripheral blood mononuclear cells (PBMC) in patients with metabolic s...

Reactive oxygen species (ROS) play essential roles in cell signaling, survival, and homeostasis. Aberrant ROS lead to disease and contribute to the aging process. Numerous enzymes and vigilant antioxidant pathways are required to regulate ROS for normal cellular health. Mitochondria are a major source of ROS, and mechanisms to prevent elevated ROS during oxidative phosphorylation require super ...

Mice genome responses to MTX (anticancer drug) and some plant (Curcuma, Ginger, Green Tee and Pomegranate) extracts were studied. Mice were intraperitoneally injected with 0.75 mg/kg chronic dose of MTX for two weeks. Mortality percentages, bone marrow cell divisions, morphological and biochemical characterization of treated mice groups were estimated. The mortality percentage was 40 % in the p...

The health and existence of coral reefs are in danger by an increasing range of environmental and anthropogenic impacts. The causes of coral reef decline include worldwide climate change, shoreline development, habitat destruction, pollution, sedimentation and overexploitation. These disasters have contributed to an estimated loss of 27% of the reefs. If the current pressure continues unabated,...

AIM Status epilepticus (SE) results in the generation of reactive oxygen species (ROS), which contribute to seizure-induced brain injury. It is well known that oxidative stress plays a pivotal role in status epilepticus (SE). Thymoquinone (TQ) is a bioactive monomer extracted from black cumin (Nigella sativa) seed oil that has anti-inflammatory, anti-cancer, and antioxidant activity in various ...

Antioxidative status study was made in cotyledons of 7days old as well as in leaf and stem tissues of 30 and 60 days old pigeon pea (Cajanus cajan) namely Asha and Maruti subjected to different doses of endosulfan in the range 0.1-1.0%. The results revealed that the activities of the antioxidative enzymes and the antioxidant contents such as the super oxide dismutase (SOD), peroxidase (POD), re...
