indium is a heavy metal belonging to group iiia. it is believed that indium may interfere with iron metabolism from the sites of absorption, transportation, utilization and storage in the cells. the present investigation was established to study and compare the binding of iron and indium to human apo-transferrin (apo-tf). pure human apo-tf was used and the binding activity of iron and indium, a...
کمپلکس های بیس(4-آمینو -3-پنتن-2- اوناتو) مس (ii)، (cu(apo)2)، بیس(4-آمینو -3-پنتن-2- اوناتو) نیکل (ii)، (ni(apo)2) و بیس(3-آمینو- 1- فنیل- 2-بوتن-1- اوناتو) مس (ii)، (cu(apbo)2)، تهیه و طیف های زیر قرمز نواحی متوسط و دور، رامان و nmr این ترکیبات ثبت شده است. برای همه این ترکیبات، آنالیز عنصری انجام شده و همچنین ساختار کمپلکس های مس، توسط اندازه گیری های پراش اشعه ایکس تایید شده است. در این ...
چکیدهمقدمه: اختلال در میزان لیپیدها و آپولیپوپروتئین‌ها از عوامل خطرساز بیماری قلبی ـ عروقی محسوب می‌شود و خوشه‌ی ژنی APOAI-CIII-AVIنقش مهمی در تنظیم سوخت و ساز و میزان لیپیدها دارد. هدف پژوهش حاضر، بررسی ارتباط 5 پلی‌مورفیسم در ناحیه‌ی ژنی Apo11q با میزان لیپیدها در سرم می‌باشد. مواد و روش‌ها: مطالعه‌ی مقطعی حاضر روی 823 نفر (340 مرد و 483 زن) از جمعیت مورد مطالعه‌ی قند و لیپید تهران (TLGS)...
the characteristics of manganese and iron binding to human apotransferrin (apo-tf) have been investigated and compared in this study. both metal ions were taken up by human apo-tf and formed complexes, with the maximum absorbances observed at 410 and 340 nm for manganese-transferrin (mn-tf) and 465 nm for iron-transferrin (fe-tf). addition of manganese (1.5 µg/ml) to the reaction mixture contai...
Background: The role of apolipoprotien E polymorphisms do not diagnostic correctly in recurrent pregnancy loss etiology but Apo E has been shown to play an important role in lipid metabolism in pregnancy. We evaluated these polymorphisms in Iranian women with unexplained recurrent pregnancy loss. Materials and Methods: 5 ml Blood were sampling from 81 women with a history of two or more consecu...
b a ckground: to compare the oxidative stress (os) factors in obese and non- obese subjects with type 2 diabetes (t2d) and to evaluate the interaction between the apolipoprotein a-ii (apo a-ii) - 265t > c polymorphism and body mass index (bmi) on os factors. m ethods : in this comparative cross-sectional study, 21 diabetes centers in tehran, iran were studied. 180 patients with t2d were divide...
Manganese is an essential trace elenent. There is a little evidence for deficiency of manganese in human , while as its toxicity has been reported in several cases. Manganese toxicity occurrs in humans exposed to high enviromental concentrations (for example workers in the dry battery production) and may be particularly important in the neonatal period. The chemical sim...
