1-butyl-3-methylimidazolium bromide ([bmim]br) as an ionic liquid promoted selectively oxidation of aliphatic and aromatic sulfides to the corresponding sulfoxides and the oxidative coupling of thiols to disulfides by nabro3 in excellent yields under neutral conditions.

Complex oxides with 4d and 5d transition-metal ions recently emerged as a new paradigm in correlated electron physics, due to the interplay between spin–orbit coupling interactions. For ions, coupling, ?, can be large 0.2–0.4 eV, which is comparable often exceeds other relevant parameters such Hund’s JH, noncubic crystal field splitting ?, hopping amplitude t. This gives rise variety of spin–or...

a series of new hexahydroquinoline and 1,4-dihydropyrimidine derivatives were synthesized. condensation of 2-methyl- thiazole-4-carboxaldehyde (1) with 1,3-cyclohexanedione and alkyl 3- aminocrotonate afforded 4-(2-methyl-thiazol-4-yl)-hexahydroquinoline while condensation of aldehyde (1) with benzoyl acetone and thiourea gave 1,4-dihydropyrimidine derivatives. the stereochemistry of 1,4-dihydr...

In the combination of 5-fluorophenyl-1, 3, 7, 9-tetra methylpyrido [2, 3, d, d, 5, 6 dipyrimidine -2, 4, 6, and 8 tetron, there are 4 rings, respectively, ring that is attached to the halogen ring A and, respectively, a ring The lower and the right to the left of the ring A are called C, B, and D. Calculations and studies show that the amount of aromatics in halogen-ring A in all cases has the ...

background α-adrenergic receptor 2a (adra2a) and angiotensin-converting enzyme (ace) genes have been variably associated with obesity and its related phenotypes in different populations worldwide. objectives this cross-sectional study aims to investigate the association of adrenergic receptor α2a (adra2a) rs553668 and angiotensin-converting enzyme (ace) i/d single nucleotide polymorphisms (snps...

An initial experimental study was conducted to evaluate the effects of binaural beats on fish growth performance. A 90-day trial with four triplicate groups was conducted with 240 zebrafish, Danio rerio, under aquarium conditions. Binaural beat file complexes were played for each aquarium using computer controlled directional speakers for 0 min d-1(Control), 90 min d-1(Group 1), 180 min d-1 (Gr...

conclusions since the severity of the behavioral symptoms in the 6-ohda-induced model of parkinson disease reflects the degree of the lesion in substantia nigra (sn) dopaminergic neurons, it is suggested that using the combination had neuroprotective effects. the obtained data suggest a synergistic neuroprotective and antiparkinsonian effect for flu, glib and b com. at least, a part of this eff...
