1. Nutritional and functional evaluation of three powder mixtures based on mexican quelites: alternative ingredients to formulate food supplements
Abstract The aim of this work was to evaluate the nutrients and antioxidant compounds of three mixtures based on leaves of Portulaca oleracea L. (P), Amaranthus hybridus L. (A) and Chenopodium berlandieri L. (C). A mixtures design was made of which 10 combinations were obtained and three of the best mixtures were selected to analysis: OP1 (P+C), OP2 (P+A) an

2. Modulation of apical Na+/H+ exchanger, NHE3, by glucose transport in rat renal proximal tubules. / Modulação do trocador NA+/H+ apical, NHE3, pelo transporte de glicose em túbulos renais in vivo.
e algumas vias de sinalização envolvidas com a reabsorção de HCO3-, além do efeito do tratamento com florizina e com streptozotocina. Para isso, utilizamos o método de microperfusão estacionária in vivo. Perfusões tubulares com solução de glicose 5mM aumentaram a reabsorção de bicarbonato em comparação com soluções contendo florizina sem gli

3. Antioxidant activity of plants foods. Structure and bioavailability of wild mulberry (Morus sp.) anthocyanins / Atividade antioxidante de alimentos vegetais. Estrutura e estudo de biodisponibilidade de antocianinas de amora silvestre (Morus sp.)
Flavonoids are of great interest in nutrition and medicine because of their potent antioxidant activity and possible protective effects on human health, reducing the risk of chronic diseases such as cardiovascular diseases and cancer. To produce a biological effects in vivo, it is essential that sufficient quantities reach the target tissue. The initial obje

4. Correction of hyperglycemia with phloridzin restores the glucagon response to glucose in insulin-deficient dogs: implications for human diabetes.
In insulin-deprived alloxan-induced diabetic dogs with severe hyperglycemia and marked hyperglucagonemia, glucagon was not suppressed by intravenous infusion of glucose at a progressively increasing rate up to 24 mg/kg of body weight per min. However, when the hyperglycemia was corrected by phloridzin, a blocker of renal tubular glucose reabsorption, the hyp

5. Effect of arterial-portal glucose gradients and phloridzin on bile glucose levels in perfused rat liver.
1. Bivascular perfused rat liver was used to study the effects of hepatic artery-portal vein glucose gradients and the effects of phloridzin on bile glucose levels. 2. Bile glucose levels were examined when glucose concentrations in the hepatic artery (HA) and portal vein (PV) inflows were equal. When the concentration of perfusate glucose was 10 mM, bile gl

6. Metabolism of Phloridzin by Erwinia herbicola: Nature of the Degradation Products, and the Purification and Properties of Phloretin Hydrolase
Erwinia herbicola Y46 degrades phloridzin to yield phloretin, phloroglucinol, and phloretic acid, when grown on defined medium containing phloridzin as the sole source of carbon. The identities of the intermediates isolated from culture filtrates were established by co-chromatography and by ultraviolet absorption spectra. Only 3 of 11 strains of this species

7. Pulmonary glucose transport in the fetal sheep.
1. In the chronically catheterized sheep fetus between 122 and 143 days gestation the concentration of D-glucose in lung liquid was very low (usually less than 0.01 mM, the lower limit of detection of the analytical method) whereas the mean plasma concentration was 0.19 mM (S.E.M. 0.4, n = 13). 2. When the lung liquid concentration of D-glucose was raised to

8. Relationship of glucagon suppression by insulin and somatostatin to the ambient glucose concentration.
The glucagon-suppressing activity of insulin and somatostatin were compared at high and low glucose concentrations. In normal dogs made hyperglucagonemic by phloridzin pretreatment, insulin and somatostatin suppressed glucagon at rates of 47 +/- 8 and 35 +/- 8%/h (NS), respectively, despite profound hypoglycemia. In severely hyperglycemic alloxan-diabetic do

10. D-galactose transport in rat intestinal brush border membrane vesicles studied with a molecular-sieve technique.
A technique using G-50 Sephadex molecular-sieve chromatography has been developed to study both the accumulation of transported solutes by rat intestinal brush border membrane vesicles and the wash-out of these solutes from pre-loaded vesicles. The extent to which D-galactose was taken up into the brush border membrane vesicles was dependent on the medium os

11. Glucose toxicity and the development of diabetes in mice with muscle-specific inactivation of GLUT4
Using cre/loxP gene targeting, transgenic mice with muscle-specific inactivation of the GLUT4 gene (muscle GLUT4 KO) were generated and shown to develop a diabetes phenotype. To determine the mechanism, we examined insulin-stimulated glucose uptake and metabolism during hyperinsulinemic-euglycemic clamp in control and muscle GLUT4 KO mice before and after de

12. Proximal Tubule Potential Difference. DEPENDENCE ON GLUCOSE, HCO3, AND AMINO ACIDS
The effect of various intraluminal substrates on the magnitude of the transepithelial potential difference (PD) across the proximal convoluted tubule (PCT) of the mammalian kidney was investigated in two ways. First, the transepithelial PD was measured before and after the removal of glucose, bicarbonate, and alanine from the lumen. Second, the effects of sp
