Both heat and chilling caused reduction in membrane protein thiol level and increased accumulation of thiobarbituric acid reactive substances in 72 hr old germinating tissues (indicators of oxidative stress) and reduced germination and early growth performances. Calcium chelator EGTA [Ethylene glycol-bis (2-aminoethylether)-N, N,N',N, tetra acetic acid] calcium channel blocker LaCI3 (Lanthanum ...

background: acne vulgaris is a chronic inflammatory disease of the pilosebaceous follicles and one of the most common skin diseases.the peeling method has been recently found to be effective for acne treatment. this study aimed to compare the efficacy of pyruvic acid 50% and salicylic acid 30% peeling in the treatment of mild to moderate acne. materials and methods: in a prospective single?blin...

Banana is a tropical crop cultivated in warm places. Chilling stress Egypt making banana crops less productive. Abscisic acid (ABA), key plant hormone, regulates metabolic and physiological processes protects plants from variety of stresses. In vitro growing shoots were pre-treated with ABA at four concentrations (0, 25, 50, 100 mM) chilled 5°C for 24 h, followed by six-day recovery period 25°C...

in other to study the effects of salicylic acid on reproductive characters of ‘elberta’ peach (prunus persica l. batsch) tree, an experiment was carried out based on randomized complete blocks design with four replications in commercial orchard, kerman, iran. the application of three concentrations of salicylic acid 0 (control), 1and 2 mm at swollen bud stage were used. results showed that appl...

The influence of low-temperature conditioning (LTC) treatment on chilling injury, glycine betaine content, and energy metabolism in loquat fruit at 1 °C storage was investigated. The results indicated that LTC treatment significantly reduced chilling injury index, ion leakage, and malondialdehyde content in loquat fruit. Betaine aldehyde hydrogenase (BADH) activity and endogenous glycine betain...

To elucidate the pathophysiological role of the hydroxyl radical (.OH) during the postischemic reperfusion of the heart, we measured the .OH product in the coronary effluent from isolated perfused rat heart during a 30-minute reperfusion period after various ischemic intervals of 5, 10, 15, 20, 30, and 60 minutes. Salicylic acid was used as the probe for .OH, and its derivative, 2,5-dihydroxybe...
