objective: ecstasy, or 3, 4 (±) methylenedioxymethamphetamine (mdma), is a potent neurotoxic drug. one of the mechanisms for its toxicity is the secondary release of glutamate. mouse embryonic stem cells (mescs) express only one glutamate receptor, the metabotropic glutamate receptor 5 (mglu5), which is involved in the maintenance and self-renewal of mescs. this study aims to investigate whethe...

Cattle grazing winter range forages exhibit interannual variation in response to supplementation. This variation may be mediated by circulating concentrations and subsequent metabolism of glucose, which are influenced by forage quality and availability. A study conducted at the Corona Range and Livestock Research Center during 2 dry years evaluated responses of young postpartum beef cows (n = 5...

conclusions to our knowledge, this is the first chronic case confirmed by the prolonged presence of hev rna in china. it is also the first reported persistent hepatitis e infection caused by hev genotype 4. case presentation here we report a chinese boy with acute lymphoblastic leukemia, who developed hepatitis e during a period of intensive chemotherapy. twenty months after the initial infecti...

Carbon membrane can be produced using a wide variety of polymer precursor materials via heat treatment process. A general concept route of precursor selection-preparation-modification-performance analysis platform for the carbon membrane has been proposed to promote the development of carbon membrane material for a wide range of application. The current review considers the recent progress of c...

Twenty Holstein cows were split into two equal groups to test the effect of daily move to a previously ungrazed strip after morning milking (MA) or afternoon milking (AA) on herbage intake, grazing behaviour, rumen characteristics and milk production using a randomized block design with three periods of 14 days each. Milking took place at 06.00 and 16.00 h. The chemical composition of grass was...

Mathematical modeling techniques have been applied to study various aspects of the ruminant, such as rumen function, postabsorptive metabolism, and product composition. This review focuses on advances made in modeling rumen fermentation and its associated rumen disorders, and energy and nutrient utilization and excretion with respect to environmental issues. Accurate prediction of fermentation ...

In this work, we report synthesis and characterization of copper nanoparticles in polymer matrix by wet-chemical reduction method using ascorbic acid as reducing agent, copper (II) sulfate as metal precursor and polyvinylpyrrolidone k-30 (PVP K-30) as surfactant agent. The reaction was carried out in a high-speed stirring mixture at room temperature under nitrogen atmosphere. Characterization o...

Aluminophosphate-5 (AlPO4-5) nano-pore zeolite was synthesized. The effect of alteration in precursor gel preparation on the morphology of zeolite was studied. The effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of AlPO4-5 zeolite been studied. A hydrothermal synthesis has been used to produce nano-pore Aluminophosphate-5 c...
