Dexmedetomidine provides protection to neurons against OGD/R-induced oxidative stress and neuronal apoptosis

PACAP protects cerebellar granule neurons against oxidative stress-induced apoptosis.

Oxidative stress, resulting from accumulation of reactive oxygen species, plays a critical role in neuronal cell death associated with neurodegenerative diseases and stroke. In the present study, we have investigated the potential neuroprotective effect of pituitary adenylate cyclase-activating polypeptide (PACAP) on oxidative stress-induced apoptosis. Incubation of cerebellar granule cells wit...

Vitamin E provides protection against in vitro oxidative stress

Over the centuries, humans have developed many ingenious methods in their attempts to control herbs, weeds, insects, invertebrates and microorganisms that constantly threatened the supply of food and fibre as well as posed a threat to public health. The aim of present study was to find out the protective nature of antioxidant property of vitamin E in against chlorpyrifos and endosulfan toxicity...

Ascorbic acid provides protection for human chondrocytes against oxidative stress.

Oxidative stress is considered to be an important cause of dysfunction in chondrocytes and articular cartilage degradation, which leads to the pathogenesis of osteoarthritis (OA) and cartilage aging. The present study aimed to assess the effects of the widely applied antioxidant, ascorbic acid (AA), on human chondrocytes against hydrogen peroxide (H2O2) in vitro. Using annexin V‑fluorescein iso...

Berberine protects against glutamate-induced oxidative stress and apoptosis in PC12 and N2a cells

Objective(s): Neurodegenerative diseases have been associated with glutamatergic dysfunction. Berberine, an isoquinoline alkaloid broadly present in different medicinal herbs, has been reported to have neuroprotective effect. In the present study, the effects of berberine against glutamate-induced oxidative damage and apoptosis were investigated. Materials and Methods: The cultured PC12 and N2a...
