Carbohydrates are ubiquitous in Nature and play vital roles in many biological systems. Therefore the synthesis of carbohydrate… Expand A new Cu-catalyzed asymmetric [3 + 3] cycloaddition of propargyl esters with cyclic enamines is reported. With a combination of… Expand Background— Asymmetrical methylarginines inhibit NO synthase activity and thereby decrease NO production. Dimethylarginine… Expand The main clinical features of two siblings from a consanguineous marriage were progressive myoclonic epilepsy without… Expand The transition-metal-catalyzed intramolecular cycloisomerization of propargylic carboxylates provides functionalized bicyclo[n.1… Expand Heparanase is an endo-beta(1-4)-D-glucuronidase that degrades heparan sulfate (HS) polysaccharide side chains. The role of… Expand Mn(Salen) complexes immobilized on sulfonic acid-functionalized SBA-15 molecular sieves (SBA-15-pr-SO3-Mn(Salen)) catalyze the… Expand We found endo-α-N-acetylgalactosaminidase in most bifidobacterial strains, which are predominant bacteria in the human colon… Expand A significant improvement of metal-catalyzed asymmetric 1,3-dipolar cycloaddition reactions of acyclic nitrones with alpha,beta… Expand CSF-1 is a glycoprotein growth factor which specifically stimulates the survival, proliferation, and differentiation of cells of… Expand
