آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولN-acetylation of etamicastat, a reversible dopamine-β-hydroxylase inhibitor.
Etamicastat [(R)-5-(2-aminoethyl)-1-(6,8-difluorochroman-3-yl)-1H-imidazole-2(3H)-thione hydrochloride] is a reversible dopamine-β-hydroxylase inhibitor that decreases norepinephrine levels in sympathetically innervated tissues. After in vivo administration, N-acetylation of etamicastat was found to be a main metabolic pathway. The purpose of the current study was to characterize the N-acetylat...
متن کاملGenetic diversity of tyrosine hydroxylase (TH) and dopamine β-hydroxylase (DBH) genes in cattle breeds
DNA from four cattle breeds was used to re-sequence all of the exons and 56% of the introns of the bovine tyrosine hydroxylase (TH) gene and 97% and 13% of the bovine dopamine β-hydroxylase (DBH) coding and non-coding sequences, respectively. Two novel single nucleotide polymorphisms (SNPs) and a microsatellite motif were found in the TH sequences. The DBH sequences contained 62 nucleotide chan...
متن کاملRapid axoplasmic transport of tyrosine hydroxylase in relation to other cytoplasmic constituents.
The transport of norepinephrine and two key enzymes involved in its synthesis, tyrosine hydroxylase (EC 1.14.3a) and dopamine beta-hydroxylase (EC 1.14.2.1), has been studied in relation to other axonal constituents in ligated chicken sciatic nerves. Norepinephrine, tyrosine hydroxylase, and dopamine beta-hydroxylase activity all increased proximal to the constriction over a 20-hr period. The r...
متن کاملSlow axoplasmic transport under scrutiny.
The origin of axoplasmic proteins is central for the biology of axons. For over fifty years axons have been considered unable to synthesize proteins and that cell bodies supply them with proteins by a slow transport mechanism. To allow for prolonged transport times, proteins were assumed to be stable, i.e., not degraded in axons. These are now textbook notions that configure the slow transport ...
