Journal ArticleDOI
Effect of amino acids on goat cauda epididymal sperm cryopreservation using a chemically defined model system.
TL;DR: The observation that amino acids and dimethyl sulfoxide had an additive effect in augmenting the cryoprotecting potential of glycerol suggests that the mechanism of their action is different from that of Glycerol.
Journal ArticleDOI
Enantioselective Syntheses of Morpholines and Their Homologues via SN2-Type Ring Opening of Aziridines and Azetidines with Haloalcohols
TL;DR: A highly regio- and stereoselective strategy for the syntheses in high yield and enantioselectivity of a variety of substituted nonracemic morpholines and their homologues is described.
Journal ArticleDOI
Extended two-dimensional metal-organic frameworks based on thiolate-copper coordination bonds.

TL;DR: Self-assembly and surface-mediated reactions of 1,3,5-tris(4-mercaptophenyl)benzene--a three-fold symmetric aromatic trithiol--are studied by means of scanning tunneling microscopy under ultrahigh-vacuum (UHV) conditions to reveal the nature of intermolecular bonds and to understand the specific role of the substrate for their formation.
Journal ArticleDOI
Platinum-catalyzed direct amination of allylic alcohols with aqueous ammonia: selective synthesis of primary allylamines.
Kalpataru Das,Ryozo Shibuya,Yasuhito Nakahara,Nicolas Germain,Takashi Ohshima,Kazushi Mashima +5 more
TL;DR: Ammonia has been one of the most important chemical feedstocks for the chemical industry since the discovery of the Harber–Bosch process and allies are ubiquitous and prevalent in various biologically active compounds.
Journal ArticleDOI
Dose dependence of acetylcholinesterase activity in neuroblastoma cells exposed to modulated radio‐frequency electromagnetic radiation
TL;DR: Radio-frequency electromagnetic radiation affects both calcium-ion release and AChE activity in nervous system-derived cells in culture in a common dose-dependent manner.
