Understanding intermolecular interactions between drugs and proteins is very important in drug delivery studies. Here, we studied different binding interactions between salicylic acid and bovine serum albumin (BSA) using electron paramagnetic resonance (EPR) spectroscopy. Salicylic acid was labeled with a stable radical (spin label) in order to monitor its mobilized (free) or immobilized (bound...

in order to evaluate the effects of drought stress and spraying of salysilic acid and chitosan on photosynthetic pigments and antioxidant enzymes of safflower an experiement was conducted as split plot randomized complete block design at the zabol university research farm in zabol, south iran during 2012. treatments were drought stress at three levels; irrigation when the soil moisture level dr...

Exposure of mango (Mangifera indica cv. Tommy Atkins) fruit to methyl jasmonate (MJ) vapors (10(-)(4) M) for 24 h at 25 degrees C reduced chilling injury during subsequent storage for 21 days at 7 degrees C and after 5 days of shelf life at 20 degrees C. The chilling tolerance induced by MJ was positively correlated with the reduction in the percent ion leakage of mango tissue. The overall qual...

banana samples were purchased from a local market in sabzevar located at northeast of iran. then samples stored at refrigerator between 5–10oc during experiments, for prevention of chilling injury, 36 samples at three replications were prepared so as bananas were peeled and sliced with a sharp knife at three thicknesses (3, 5 and 10 mm) and then treated by three pretreatment methods (t1: chemic...

Some herbal medications induce acute kidney injury. The acute kidney injuries caused by herbal medications are mild and commonly treated by palliative care. A 51-years-old man who drank the juice squeezed from the raw tubers of Dioscorea quinqueloba (D. quinqueloba) was admitted with nausea, vomiting and chilling. He developed a seizure with decreased level of consciousness. He was diagnosed wi...

The Gram-negative bacterium Pseudomonas aeruginosa produces the phenolic siderophore pyochelin. Salicylic acid is an intermediate in the pyochelin biosynthetic pathway, and mutants blocked in salicylic acid biosynthesis (Sal-) are able to incorporate exogenously supplied salicylic acid into pyochelin. A P. aeruginosa Sal- mutant was incubated with 13 salicylic acid analogues and was found to in...

Peaches are stored at low temperatures to delay ripening and increase postharvest life. However some varieties are susceptible to chilling injury,which leads to fruit mealiness, browning and flesh bleeding. In order to identify potentialmarkers associated with chilling injury,we performed proteomic analyses on a segregating population with contrasting susceptibility to chilling-induced mealines...
