Sorting of three secretory proteins to distinct secretory granules in acidophilic cells of cow anterior pituitary
The distribution of three proteins discharged by regulated exocytosis--growth hormone (GH), prolactin (PRL), and secretogranin II (SgII)--was investigated by double immunolabeling of ultrathin frozen sections in the acidophilic cells of the bovine pituitary. In mammotrophs, heavy PRL labeling was observed over secretory granule matrices (including the immature matrices at the trans Golgi surfac...

نمایشنامه به پیروی از ماهیت دوگانه اش، کارکردی دوگانه به خود می گیرد، بدین معنا که در هر دو نظام ادبی و تئاتری می تواند کارکردی مختص به خود یابد. هدف از انجام این پژوهش یافتن تفاوت ها میان ترجمه صفحه و ترجمه صحنه است.. پرسش مطرح شده عبارتست از: بر اساس مدل ارائه شده توسط لدوسر (1995)، تفاوت های ترجمه صفحه و ترجمه صحنه در چیست؟ یافته های این پژوهش حاکی از آن است که ترجمه صفحه به نمایشنامه ا...
An EPQ Model for Product Life Cycle (Maturity Stage) with Deteriorating Items and Shortages
A product life cycle is the life span of a product in which the period begins with the initial product specification and ends with the withdrawal from the market of both the product and its support. A product life cycle can be divided into several stages characterized by the revenue generated by the product. This study investigates inventory control policies in a manufacturing system for a si...
متن کاملIsolation and Biological Properties of Secretory Granules from Rat Anterior Pituitary Glands
A method is described for the isolation of secretory granules from rat anterior pituitary glands. The method consists of differential and isopycnic gradient centrifugations, followed by filtration of the zones containing granules on Nuclepore filters to remove mitochondria. Highly purified granules were obtained as indicated by electron microscopy. Major parts of the thyrotropin (TSH) and adren...
متن کاملFormation and release of secretory granules during mitosis in the anterior pituitary gland.
Electron microscopic images indicating exocytosis of secretory granules were obtained in rat prolactin cells undergoing mitosis at the estrus in the female reproductive cycle. Immature secretory granules looking like small cored vesicles were found among chromosomes and microtubules of the mitotic spindle. Golgi apparatus was fragmented and its small elements mostly consisting of vesicles were ...
