[ 1 ] - بررسی هیپرسگمانتاسیون نوتروفیلی درزنان جوان مبتلا به کمبود آهن
هدف: افزایش لوب نوتروفیل یا هیپرسگمانتاسیون نوتروفیلی، یک یافته هماتولوژیکی است که در کمبود کوبالامین و اسید فولیک به وجود می آید. مطالعات و گزارشات ضد و نقیضی زیادی بر وجود ارتباط بین هیپرسگمانتاسیون نوتروفیلی (NH) و فقرآهن دلالت می کنند. این مطالعه به بررسی ارتباط فقر آهن و آنمی فقرآهن با هیپرسگمانتاسیون نوتروفیلی می پردازد. در این ارتباط اثر کمبود فولات نیز مورد بررسی قرار گرفته است. روش بر...
[ 2 ] - The Human Thioredoxin System: Modifications and Clinical Applications
The thioredoxin system, comprising thioredoxin (Trx), thioredoxin reductase (TrxR) and NADPH, is one of the major cellular antioxidant systems, implicated in a large and growing number of biological functions. Trx acts as an oxidoreductase via a highly conserved dithiol/disulfide motif located in the active site ( Trp-Cys-Gly-Pro- Cys-Lys-). Different factors are involved in the regulation of T...
