GLUT2-null mice are hyperglycemic, hypoinsulinemic, hyperglucagonemic, and glycosuric and die within the first 3 weeks of life. Their endocrine pancreas shows a loss of first phase glucose-stimulated insulin secretion (GSIS) and inverse alpha to beta cell ...
Previous studies have demonstrated that activation of glutamate transporters promotes glycolysis in astrocytes. Current evidence indicates that compounds such as threo-beta-hydroxyaspartate (THA) are both competitive inhibitors and substrates for glutamate ...
To determine whether acute hyperglycemia changes the hyperemic response to functional activation of brain, the area and magnitude of the activation were measured in healthy volunteers maintained at euglycemia and then at hyperglycemia using the hyperglycem ...
The functional role of glutamate decarboxylase (GAD) and its product GABA in pancreatic islets has remained elusive. Mouse β-cells express the larger isoform GAD67, whereas human islets express only the smaller isoform GAD65. We have generated two lines of ...
One microband of an array of four microband electrodes (1 mm long and 25 μm wide with a 25 μm gap) was modified with glucose oxidase by direct electrochemically assisted immobilisation, giving a stable microbiosensor with an apparent Michaelis-Menten const ...
OBJECTIVE: The Pro12Ala polymorphism of the Peroxisome Proliferator Activated Receptor gamma2 (PPARgamma2) gene has been inconsistently associated with body mass index variations and non-insulin-dependent diabetes mellitus (NIDDM). We investigated the impa ...

A novel approach for indirect biomass detn. in case of non-const. specific metabolic rates is reported. Specific glucose consumption rate was detd. during a first calibration culture for both free suspended and immobilized cells. It was expressed as a line ...
Using optimized, asymmetric radiofrequency (RF) pulses for slice selection, the authors demonstrate that stimulated echo acquisition mode (STEAM) localization with ultra-short echo time (1 ms) is possible. Water suppression was designed to minimize sensiti ...
Resolved localized nuclear magnetic resonance (NMR) signals of 1H bound to 13C label in the carbon positions of glutamate C4, C3 and glutamine C4, C3, as well as in aspartate C3, lactate C3, alanine C3, γ,-aminobutyric acid C3, and glucose C1 were simultan ...
