Oral Administration of 4-Hydroxy-3-Methoxycinnamaldehyde Attenuates Atopic Dermatitis by Inhibiting T Cell and Keratinocyte Activation
Atopic dermatitis (AD) is a skin condition caused by an imbalance of distinct subsets of T helper cells. Previously, we showed that 4-hydroxy-3-methoxycinnamaldehyde (4H3MC) inhibits T cell activation but does not induce apoptosis. Here, we examined the mechanism underlying the inhibitory effect of 4H3MC on AD both in vivo and in vitro. We sought to test the pharmacological effects of 4H3MC usi...

تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...
15 صفحه اولDEVELOPMENT OF A METHOD FOR THE DETERMINATION OF 4-HYDROXY-3-METHOXYMANDELIC ACID (VANILLYLMANDELIC ACID) IN URINE BY PAPER CHROMATOGRAPHY
We have developed a simple and precise paper chromatographic method for the determination of 4-hydroxy-3-methoxymandelic acid (VMA) in urine. Concentrations of VMA in patients with neuroblastoma were increased in comparison to controls. The linearity was excellent in the concentration range tested. The within-assay coefficient of variation for control and patient urine was less than 2.2%. ...
متن کامل17α-Hydroxy-4-pregenen-3-one (17 αP) assay, using acetylcholinesterase enzyme as tracer
17a-hydroxy-4-pregnen-3-one (17aP) hormone is a precursor of other steroid hormones and radioimmunoassay has already been used to measure it, but a simple and rapid "Enzyme Linked Immunosorbant Assay" (ELISA) is described and validated here. A general procedure for prepara-tion of the acetylcholinesterase labelled steroid is described, which is applicable to any steroid. Use of acetyl...
