melanin pigment plays a critical role in camouflage and protection against harmful effects of solar radiation. melanogenesis is under complex regulatory control by multiple agents. tyrosinase is a multifunctional, which catalyzes the first two steps in mammalian melanogenesis. in this study, inhibitory effects of astragalus fasciculifolius and astragalus gypsicolus on diphenolase acti...
Only a few species of the large Astragalus genus, widely used for medicinal purposes, have been thoroughly studied for phytochemical composition. The aim of our research was to investigate the rarely studied species A. glycyphyllos L. and A. cicer L. for the distribution of mineral elements and phytochemicals in whole plants at two growth stages and in morphological fractions. We also investiga...
Astragalus Granule Prevents Ca2+ Current Remodeling in Heart Failure by the Downregulation of CaMKII
BACKGROUND Astragalus was broadly used for treating heart failure (HF) and arrhythmias in East Asia for thousands of years. Astragalus granule (AG), extracted from Astragalus, shows beneficial effect on the treatment of HF in clinical research. We hypothesized that administration of AG prevents the remodeling of L-type Ca2+ current (ICa-L) in HF mice by the downregulation of Ca2+/calmodulin-dep...
The ∼37 million-year-old Birket Qarun Locality 2 (BQ-2), in the Birket Qarun Formation of Egypt's Fayum Depression, yields evidence for a diverse primate fauna, including the earliest known lorisiforms, parapithecoid anthropoids, and Afradapis longicristatus, a large folivorous adapiform. Phylogenetic analysis has placed Afradapis as a stem strepsirrhine within a clade of caenopithecine adapifo...
دی اکسیدکربن اتمسفر در دهه های اخیر افزایش قابل توجهی داشته است. شیوه های مدیریت اراضی، شرایطی را برای تعدیل افزایش غلظت 2co فراهم می آورند که طی آن کربن اضافی از طریق ذخیره شدن در بیوماس گیاهی و مواد آلی خاک ترسیب می گردد، این فرایند را اصطلاحاً ترسیب کربن خاکی گویند. اکوسیستم های مرتعی به دلیل اینکه نیمی از کل اراضی جهان را دربر گرفته اند، قابلیت بالایی در ترسیب کربن دارند. گون زارهای ایران با...

In vitro clonal micropropagation of Astragalus gorodkovii Jurtz., Astragalus gorczakovsky L. Vassil.
Abstract. Microclonal propagation of rare plant species solves the problem biodiversity conservation, because received explants can be introduced into natural conditions to maintain stability communities. The purpose research was obtain in vitro cultures plants from Fabaceae family: Astragalus gorodkovii and gorczakovskii. Materials methods: seeds were selected population Komi Republic 2004. Se...
