Glucose Transporters in the Transepithelial Transport of Glucose
Journal of Electron Microscopy, 1996Glucose transporters are integral membrane proteins that mediate the transport of glucose and structurally-related substances across the cellular membranes. Two families of glucose transporter have been identified: the facilitated-diffusion glucose transporter family (GLUT family), and the NA(+)-dependent glucose transporter one (SGLT family).

Nature Reviews Neuroscience, 2008
Neurons have a constantly high glucose demand, and unlike muscle cells they cannot accommodate episodic glucose uptake under the influence of insulin. Neuronal glucose uptake depends on the extracellular concentration of glucose, and cellular damage can ensue after persistent episodes of hyperglycaemia--a phenomenon referred to as glucose neurotoxicity.

Glucose sensor with immobilized glucose oxidase-glucose isomerase membrane
Journal of Molecular Catalysis, 1981Abstract A glucose sensor, i.e., an oxygen detection electrode with immobilized glucose oxidase, has been studied by several researchers as a novel analytical technique which can simplify tedious steps in conventional methods of glucose determination. In a glucose sensor of such construction, any glocuse oxidase inhibition will impair the performance

Glucose, glucose transporters and neurogenesis
2008Since the pioneering work of Altman in the late 60's, much has been learned about the generation of neurons in the adult brains of several species, including mice, rats, and humans. An underlying assumption is that these newborn neurons acquire their energy, in the form of glucose, in a similar manner to mature neurons: via glucose transporters.

Use of [3-3H]glucose and [6-14C]glucose to measure glucose turnover and glucose metabolism in humans
American Journal of Physiology-Endocrinology and Metabolism, 1992[3-3H]glucose is frequently used to measure glucose turnover in humans. If fructose 6-phosphate-fructose 1,6-diphosphate cycling (Fpc) is negligible in both liver and muscle, then [3-3H]- and [6-14C]glucose (corrected for Cori cycle activity) should provide equivalent measures of glucose turnover.

Measuring brain glucose phosphorylation with labeled glucose
American Journal of Physiology-Endocrinology and Metabolism, 1988This study tested whether glucose labeled at the C-6 position generates metabolites that leave brain so rapidly that C-6-labeled glucose cannot be used to measure brain glucose phosphorylation (CMRGlc). In pentobarbital-anesthetized rats, the parietal cortex uptake of [14C]glucose labeled in the C-6 position was followed for times ranging from 10 s to

Effects of plasma glucose concentration on glucose utilization and glucose clearance in normal man
Diabetes, 1981Glucose clearance (glucose utilization ÷ plasma glucose) is commonly used to assess glucose utilization under conditions in which plasma glucose concentrations vary. The validity of this practice requires that glucose clearance itself be independent of plasma glucose concentration.

Brain glucose sensing mechanism and glucose homeostasis
Current Opinion in Clinical Nutrition and Metabolic Care, 2002Glucose homeostasis must be finely regulated. Changes in glucose levels elicit a complex neuroendocrine response that prevents or rapidly corrects hyper- or hypoglycemia. It is well established that different parts of the brain, particularly the hypothalamus and the brain stem, are important centres involved in the monitoring of glucose status and the ...
