This Kinetic, Bioavailability, and Metabolism Study of RRR-alpha-Tocopherol in Healthy Adults Suggests Lower Intake Requirements than Previous Estimates

submitted by: jnusda
Kinetic models enable nutrient needs and kinetic behaviors to be quantified and provide mechanistic insights into metabolism. Therefore, we modeled and quantified the kinetics, bioavailability, and metabolism of RRR-alpha-tocopherol in 12 healthy adults. Six men and 6 women, aged 27 +/- 6 y, each ingested 1.81 nmol of 14C-RRR-alpha-tocopherol; each dose had 3.70 kBq of 14C. Complete collections of urine and feces were made over the first 21d from dosing. Serial blood samples were drawn over...

New Perspectives of Energy Storage Materials

submitted by: RASEIBoulder
Summary: Energy storage in the electrochemical form is attractive because of its high efficiency and fast response time. New and improved materials for energy storage are urgently required to make more efficient use of our finite supply of fossil fuels, and to enable the effective use of renewable energy sources. In this seminar, I will discuss a few new perspectives for energy storage materials including new Li intercalation compounds, new Na intercalation compounds and new...

Directed Assembly of Anisotropic Particles - Fundamentals and Energy-related Applications

submitted by: RASEIBoulder
Summary: Spherical colloids with isotropic properties have been used as building blocks to assemble a variety of 2D and 3D structures in past, such as FCC, HCP, and BCT crystals. Anisotropic particles are, however, more faithful mimics of molecules and atoms because of the anisotropic interactions. Current synthetic methods are versatile and accurate enough to create and tune the anisotropic properties in geometry, chemical composition, surface functionality, and physical properties. In the...

Dietary Selenium Deficiency Partially Rescues Type 2 Diabetes–Like Phenotypes of Glutathione Peroxidase-1–Overexpressing Male Mice

submitted by: xlei
This study was conducted to determine whether dietary Se deficiency precluded overproduction of glutathione peroxidase-1 (GPX1) activity in mice overexpressing (OE) this gene and thus rescued their type 2 diabetes–like phenotypes. A total of 20 male OE and wild-type (WT) mice were fed an Se-deficient (<0.02 mg/kg) diet or an Se-supplemented (0.3 mg/kg as sodium selenite) diet from 1 to 5 mo of age. Dietary Se deficiency eliminated or attenuated (P < 0.05) genotype differences in...
