Environmental Stress and Aspirin

Stress , Environmental

Acute An exposure to an environmental stress that is brief in relation to the temporal scale of the biological system exposed. Biosphere All the plants and animals on Earth, together with the habitat they need for long-term survival. Biotic impoverishment The decline of a species to the point of having little or no ecological significance. Chronic An exposure to an environmental stress that is ...

Dietary antioxidants and environmental stress.

Air is one of our most important natural resources; however, it is also in the front line for receiving environmental pollution. Air quality decreased markedly following the industrial revolution, but it was not until the great London Smog in 1952 that air quality made it onto the political agenda. The introduction of the Clean Air Act in 1956 led to dramatic decreases in black smoke and SO2 co...

Environmental stress and flowering time

After the f loral transition the shoot apical meristem (SAM) changes its identity switching from vegetative to reproductive. In annual Arabidopsis ecotypes, the transition to f lowering is strongly promoted by variations in day length (photoperiod). The photoperiodic pathway promotes f lowering when Arabidopsis plants are exposed to long days (LDs) conditions (typical of spring and summer). Pho...

Oxidative Stress – Environmental Induction

H(2)S-Releasing Aspirin Protects against Aspirin-Induced Gastric Injury via Reducing Oxidative Stress

The aim of this study was to examine the effect of ACS14, a hydrogen sulfide (H(2)S)-releasing derivative of aspirin (Asp), on Asp-induced gastric injury. Gastric hemorrhagic lesions were induced by intragastric administration of Asp (200 mg/kg, suspended in 0.5% carboxymethyl cellulose solutions) in a volume of 1 ml/100 g body weight. ACS14 (1, 5 or 10 mg/kg) was given 30 min before the Asp ad...
