IMMUNOFLUORESCENT STUDIES ON TYROSINE HYDROXYLASE: APPLICATION FOR ITS AXOPLASMIC TRANSPORT

Rapid 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...

Studies on tyrosine hydroxylase from bovine adrenal medulla.

Approximately 90% of the total tyrosine hydroxylase activity of bovine adrenal medulla homogenates was localized in the particulate fraction of the homogenate. The particulate enzyme was solubilized by incubation with trypsin, and the solubilized enzyme was partially purified. This enzyme was found to behave like the tyrosine hydroxylase which had been purified from the supernatant fraction by ...

در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...

Slow 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 ...
