Published models of mammalian whole-body glucose metabolism generally assume that glucose uptake is proportional to circulating glucose concentration at constant insulin concentration. One widely used model labels the increased whole-body glucose uptake seen with increased venous glucose concentration as "glucose effectiveness." In 1956 and 1957, we found on average no change in forearm glucose...

The glucose transporter GLUT2 is expressed predominantly in the liver. Previous studies have shown that glucose increases GLUT2 mRNA concentration in primary cultures of rat hepatocytes. Since insulin controls the glucose metabolism in the liver, it could be involved in the regulation of GLUT2 gene expression. In vivo, hyperinsulinaemia induced a transient inhibitory effect on liver GLUT2 gene ...

carbon spheres were fabricated by hydrothermal method and their structural properties were investigated. carbon spheres with average sizes around of 230, 320 and 430 nm were synthesized in different concentration of glucose aqueous solution and different hydrothermal reaction time. the temperature of 180 °c by a hydrothermal reaction was fixed in all of glucose concentration and hydrothermal re...

Effects of different carbon sources on growth and production of antifungal agent(s) by Gymnopilus spectabilis were investigated. Different carbon sources including; Glucose, fructose, lactose, maltose, manitol and sucrose at the concentration of 10 g/l and slow releasing carbon sources including malt extract and soluble starch at the concentration of 2g/l were used. Inhibition of spore germinat...

A microfluidic device capable of precise chemical control is helpful to mimic tumor microenvironments in vitro, which are closely associated with malignant progression, including metastasis. Cancer cells under a concentration gradient of oxygen and other sustenance materials inside a tumor in vivo have recently been reported to increase the probability of metastasis. The influence of glucose co...

background: clinical evidence indicates the diabetes-induced impairment of osteogenesis caused by a decrease in osteoblast activity. flavonoids can increase the differentiation and mineralization of osteoblasts in a high-glucose state. however, some flavonoids such as luteolin may have the potential to induce cytotoxicity in osteoblast-like cells. this study was performed to investigate whether...

objective(s): hyperglycemia, oxidative stress and apoptosis have key roles in pathogenesis of diabetic neuropathy. there are local renin-angiotensin systems (rass) in different tissues such as neural tissue. local rass are involved in physiological and pathophysiological processes such as inflammation, proliferation and apoptosis. this study aimed to investigate the role of local renin-angioten...
