[ 1 ] - The effects of transdermal estrogen delivery on bone mineral density in postmenopausal women: A meta-analysis

Background: Due to its minimal systematic adverse effects, transdermal estrogen is widely used for the prevention of osteoporosis in postmenopausal women.The present meta-analysis aimed to clarify the effects of transdermal estrogen on bone mineral density (BMD) of postmenopausal women.Methods: Studies were identified by searching electronic databases including Cochrane Library, MEDLINE, Embase...

[ 2 ] - Simultaneous diagnosis and drug delivery by silymarin-loaded magnetic nanoparticles

Objective(s): The aim of this work was to prepare and characterize magnetic nanoparticles (MNPs) as theranostic system to act simultaneously as drug carrier and MRI contrast agent. Chitosan-coated MNPs (CMNPs) were prepared and loaded with silymarin. Silymarin-loaded CMNPs were characterized with various techniques and their potential as MRI contrast agent was also evaluated. Materials and Meth...

[ 3 ] - نقش پروژه‌های آبخیزداری در کاهش فرسایش و رسوب حوضه‌های آبخیز

فرسایش خاک پدیده‌ای است که به‌‌ویژه در شرایط تشدید شونده منجر به تخریب و از بین رفتن خاک می‌شود. ازآنجاکه حیات جوامع انسانی مستلزم وجود آب و خاک است، برای جلوگیری از فرسایش خاک و هدر رفتن آب، عملیات مختلف بیولوژیکی و مکانیکی برای کاهش فرسایش، کنترل رواناب و بهبود شرایط پوشش گیاهی اجرا می‌شوند. در این تحقیق به‌منظور ارزیابی نقش عملیات آبخیزداری (بیولوژیکی و مکانیکی) بر فرسایش و رسوب حوضه چهل‌گزی...
