Elevated blood levels of homocysteine (Hcy), hyperhomocysteinemia or homocystinuria, have been associated with various diseases and conditions. Homocysteine thiolactone (Hcy TL) is a metabolite of Hcy and reacts with amine groups in proteins to form stable amides, homocystamides, or N-homocysteinylated proteins. It has been proposed that protein… (More)
The trefoil factor family (TFF) is a group of short secretory peptides of gastric mucous neck cells. The loss of TFF2 protein expression enhances gastric inflammation and occurs in gastric cancer. In this study, we examined the effect of TFF2 on gastric cancer cell lines in vitro and characterized the interaction between TFF2 and Sp3, including the… (More)
A novel stimuli-responsive organic/inorganic nanocomposite hydrogel (NC hydrogel) with excellent mechanical properties was synthesized by in situ polymerization of 2-(2-methoxyethoxy) ethyl methacrylate (MEO(2)MA), oligo (ethylene glycol) methacrylate (OEGMA) and acrylic acid (AAc), as the polymeric matrix (PMOA), and fibrillar attpulgite (AT), as the… (More)
A fructose-derived diacetate ketone has been shown to be an effective catalyst for asymmetric epoxidation. High ee values have been obtained for a variety of trans and trisubstituted olefins including electron-deficient alpha,beta-unsaturated esters as well as certain cis olefins.
INTRODUCTION We describe a 10-year-old Chinese boy with features of Charcot-Marie-Tooth disease (CMT) and Duchenne muscular dystrophy (DMD). METHODS Case report. RESULTS Weakness and mild sensory loss in the distal extremities, pes cavus, and nerve conduction findings suggested demyelinating neuropathy, while moderate calf pseudohypertrophy, proximal… (More)
[reaction: see text] A series of boronic acids were attached to a fluorous tag by esterification. Functional transformations of these boronates together with the fluorous Suzuki coupling reaction illustrated their usefulness in fluorous-phase techniques.
Palladium catalyzed C-C couplings were used to connect (pyridin-2-yl)hydrazine to organic substrates, including a phenylalanine derivative, providing a new method for introducing this important ligand.
