اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولZinc transporters belonging to the Cation Diffusion Facilitator (CDF) family have complementary roles in transporting zinc out of the cytosol
Zinc is an essential trace element that is required for the function of a large number of proteins. As these zinc-binding proteins are found within the cytosol and organelles, all eukaryotes require mechanisms to ensure that zinc is delivered to organelles, even under conditions of zinc deficiency. Although many zinc transporters belonging to the Cation Diffusion Facilitator (CDF) families have...
متن کاملPDTC inhibits picornavirus polyprotein processing and RNA replication by transporting zinc ions into cells.
Previously, it was shown that pyrrolidine dithiocarbamate (PDTC) inhibits proteolytic polyprotein processing and replication of human rhinovirus by transporting metal ions into cells. Here, it is shown that PDTC also inhibits replication of two other picornaviruses: coxsackievirus B3 (CVB3), a closely related virus that belongs to the genus Enterovirus, and mengovirus, an encephalomyocarditis v...
متن کاملK+)-transporting ATPase system
The distribution of free thiol groups associated with the membrane proteins of the purified pig gastric microsomal vesicles was quantified, and the relation of thiol groups to the function of the gastric (H+ + K+)-transporting ATPase system was investigated. Two different thiol-specific agents, carboxypyridine disulphide (CPDS) and N(1-naphthyl)maleimide (NNM) were used for the study. The struc...
متن کاملThe effects of a dietary zinc supplement during lactation on longitudinal changes in maternal zinc status and milk zinc concentrations13
Dietary zinc intakes, selected biochemical indices of zinc status, and milk zinc concentrations were determined at monthly intervals throughout lactation for 53 middle-income lactating women, 14 of whom received a daily supplement of 15 mg zinc. Overall mean dietary zinc intake for the non-supplemented group (NZS) was 10.7 ± 4.1 mg/day ( ± SD). The mean dietary zinc intake of the zinc supplemen...
