this work described an efficient pseudo four-component synthesis of (10e)-n-benzylidene-2-phenylh-imidazo[1,2-a]pyridin-3-amine derivatives from 2-aminopyridin, malononitrile and arylaldehydes in the presence of naoh under solvent-free and conventional heating condition in good to excellent yields. a wide range of aromatic aldehydes would easily undergo condensations with 2-aminopyridin and mal...

normal 0 false false false en-us x-none ar-sa background: alzheimer's disease (ad) is a progressive neurodegenerative disease in which endothelial cell (ec) can be affected. in brain, functional changes in ecs contribute to reductions in resting blood flow. furthermore, angiotensin-converting enzyme inhibitors (ace-i) have beneficial effects on endothelial dysfunction. this is the first study t...

imidazo[2,1-b]thiazoles are obtaind in excellent yields from the addition reaction between thiohydantoin and ethylbromopyruvate.  these imidazo[2,1-b]thiazoles in the presence of p-tsa in boiling toluene refluxed for 2.5 hours led to imidazo[2,1-b]thiazole-3-carboxylates in elimination reactions

normal 0 false false false en-us x-none ar-sa background: exposure to some environmental agent such as different nutrition and contact with allergens may have a role in developing multiple sclerosis (ms). the present study was aimed to evaluate the cow’s milk allergy (cma) in ms patients compared to healthy controls. materials and methods: between march 2012 and july 2012, 48 ms patients were s...

a new kinetic spectrophotometic method for the determination of trace amount chromium (iii) in teareal samples has been described based on it s the catalytic effect on the oxidations of 1 - ( 2 –pyridylazo ) - 2 - naphthol, (pan), by potassium bromated in sulfuric acid. the reaction is followedspec- trophotometrically by measuring the decrease in the absorbance at 469 nm. under the optimumcondi...

existence of 2-methylpropane-2-thiol as an organosulfur and odorant compound in the soil could causes environmental problem and social dissatisfaction. in this study, remediation of this type of thiol using ultrasound is investigated. central composite design (ccd) based on response surface model (rsm) was used to obtain effects of the main factor (power, sonication time and amount of water) an...

normal 0 false false false en-us x-none ar-sa epilepsy is more common in patients with multiple sclerosis (ms) than in the general population, occurring in 2%–3% of patients. convulsions may be either tonic–clonic in nature or partial complex. in these individuals, seizures most likely result from lesions present in the cerebral cortex and subcortical white matter. a jacksonian seizure is a typ...

normal 0 false false false en-us x-none ar-sa background: migraine is common worldwide. in recent years, vitamin d deficiency has been determined as a global health problem. a few studies have shown inverse relationship between serum vitamin d levels and headache. thus, in this study, we assessed relationship between serum vitamin d levels with migraine. materials and methods: the present study...
