A one-step reductive ligation mediated disulfide formation of S-nitrosothiols was developed. This reaction involves the reaction of the S-nitroso group with phosphine-thioesters to form sulfenamide and thiolate intermediates, which then undergo a fast intermolecular disulfide formation to form stable conjugates. This reaction can be used to design new biosensors of S-nitrosated proteins.
In the centrosymmetric title compound, [Cd(2)(C(13)H(12)NOS(2))(4)], pairs of dithio-carbamate ligands exhibit different structural functions. Each of the terminal ligands is bidentately coordinated to one Cd(II) atom and forms a planar four-membered CS(2)Cd chelate ring, whereas pairs of the tridentate bridging ligands link two neighbouring Cd(II) atoms, forming extended eight-membered C(2)S(4...
introduction: a large body of evidence points to oxidative stress as prime candidate mediating the behavioral impairments and memory deficits in alzheimer's disease (ad). it has been demonstrated that hyperoxia preconditioning activates complex endogenous neuroprotective mechanisms including an increase in capacity of antioxidant defence mechanisms. the aim of this study was to investigate...

To investigate the effects of calorie restriction (CR) on behavioral performance and expression of SIRT1 and SIRT5 in rat cerebral tissues. Beginning at 18 months of age, 60 rats were randomly divided into a CR group (n = 30) and a group that remained fed ad libitum (AL; n = 30). CR rats were restricted to a diet of 60% of their daily food consumption. After 6 months of CR, CR rats displayed a ...
تاکنون تعداد قابل توجهی شرط کافی برای همیلتنی بودن گراف های همبند با n رأس ثابت شده است. از مشهورترین آن ها می توان به شروط دیراک( 1952 )( اگر?(g)?n/2) و اُور(1960)( برای هر دو رأس نامجاورِ uوv ، d(u)+d(v)?n) اشاره کرد. پس از آن، فَن(1984) این دو شرط را گسترش داد و ثابت کرد که اگر g، ساده و 2-همبند با n رأس باشد و برای هر جفت رأس نامجاورِ xوy که d(x,y)=2، داشته باشیم: max{d(x),d(y)}? n/2، g همیلتنی...
