Ecophysiological responses to different forest patch type of two codominant tree seedlings

According to gap-phase dynamics theory, forests can be divided into four distinct patch types: gap patch (G), building patch (B), mature patch (M), and degeneration patch (D). Varying light conditions across patch types are one of the most important factors affecting the coexistence of vegetation. Mechanisms of coexistence can be understood through detailed knowledge of ecophysiological respons...

بررسی پلی مورفیسم آلل های HLA-DRB,DQA1,DQB1 در بیماران هپاتیت B مزمن در مقایسه با افراد سالم به روش PCR-SSP

Background: The outcome of acute hepatitis B infection may be influenced by host genetic factors like human leukocyte antigen (HLA). To investigate the association between the HLA-DRB, DQA1 and DQB1 alleles and chronic hepatitis B infection, 50 patients with chronic hepatitis B (based on 6 months positive of HBsAg and HBc antibody and HBeAg and antibody by serological test), were selected from ...

Composition of Glycosaminoglycans in Elasmobranchs including Several Deep-Sea Sharks: Identification of Chondroitin/Dermatan Sulfate from the Dried Fins of Isurus oxyrinchus and Prionace glauca

Shark fin, used as a food, is a rich source of glycosaminoglyans (GAGs), acidic polysaccharides having important biological activities, suggesting their nutraceutical and pharmaceutical application. A comprehensive survey of GAGs derived from the fin was performed on 11 elasmobranchs, including several deep sea sharks. Chondroitin sulfate (CS) and hyaluronic acid (HA) were found in Isurus oxyri...

Functionally closed sets and functionally convex sets in real Banach spaces

‎Let $X$ be a real normed  space, then  $C(subseteq X)$  is  functionally  convex  (briefly, $F$-convex), if  $T(C)subseteq Bbb R $ is  convex for all bounded linear transformations $Tin B(X,R)$; and $K(subseteq X)$  is  functionally   closed (briefly, $F$-closed), if  $T(K)subseteq Bbb R $ is  closed  for all bounded linear transformations $Tin B(X,R)$. We improve the    Krein-Milman theorem  ...
