Vitamin E-blended UHMWPE with a Gradient Vitamin E Concentration
INTRODUCTION: Vitamin E-stabilized, radiation cross-linked ultra-high molecular weight polyethylene (UHMWPE) is used in total joint arthroplasty as a bearing surface with low wear and improved mechanical properties compared to irradiated and melted UHMWPE [1]. Vitamin E stabilizes the residual free radicals trapped in the material after irradiation and ensures oxidative resistance, thus resulti...
متن کاملInvestigation of ANP Plasma Concentration in Normal Pregnancy and Preeclampsia
با وجود شواهد روزافزونی که بیانگر نقش احتمالی ANP در هموستاز طبیعی مایعات بدن است، اما هنوز اهمیت نقش این پیتید در سلامت و بیماری بدرستی مشخص نیست. بر اثر ازدیاد فشار دهلیزی و تعداد انقباضات آن، ANP از میوسیت های دهلیزی ترشح می شود. تزریق مقادیر زیادی از ANP صناعی به انسان و حیوان سبب کاهش فشار سیستمیک دهلیزی و افزایش دفع سدیم و برقراری دیورز می گردد. مطالعات اخیر بر روی تأثیر تزریق ANP صناعی ...
متن کاملPlasma vitamin E values in the newborn.
Plasma vitamin E values of newborn infants in a Coloured population of Cape Town have been determined. The mean plasma alpha-tocopherol value was 3,2 +/- 0,8 mg/l. A significant correlation between the plasma alpha-tocopherol level and plasma total lipid content (r = 0,45; P less than 0,001) and plasma cholesterol level (r = 0,65; P less than 0,001) has been found. However, maternal and neonata...
متن کاملVitamin C intake and plasma ascorbic acid concentration in adolescents
The relationship between vitamin C intake and status was investigated in a group of adolescents (13-14 years old). Dietary intakes were assessed using a 7 d weighed dietary record method, coupled with the collection of duplicate diets. Vitamin C intakes calculated using food composition tables were compared with values obtained by direct analysis of duplicate diets. Vitamin C status was judged ...
