This paper aims at evaluating the impact of vitamins intake in the prevention of gastroesophageal reflux disease (GERD), Barrett's oesophagus (BE), and oesophageal adenocarcinoma (EADC). It concentrates primarily on the antioxidant vitamins A, C and E. There were 180 subjects included in the trial, 109 males and 71 females, which were divided in the four groups (70 patients with GERD, 20 patien...

We tested the hypothesis that green tea prevents diabetes-related tissue dysfunctions attributable to oxidation. Diabetic rats were treated daily with tap water, vitamins C and E, or fresh Japanese green tea extract. After 12 months, body weights were decreased, whereas glycated lysine in aorta, tendon, and plasma were increased by diabetes (P < 0.001) but unaffected by treatment. Erythrocyte g...

Hemolytic effect of some water-soluble vitamins (niacin B5, pyridoxine B6, thiamine B1 and ascorbic and acid C) on erythrocytes was studied spectrophotometrically at relatively high concentration. The oxidation mechanism of hemoglobin was the same for the used vitamins. Vitamin C was the strongest hemolytic agent in comparison with the other vitamins, while vitamin B1 is the weakest one. The re...

BACKGROUND Improvements in culture media formulations have led to an increase in the ability of sheep embryo in culture throughout the preimplantation period. OBJECTIVE This study was carried out to evaluate the effects of various concentrations of MEM vitamins during in vitro maturation of sheep oocytes and subsequent embryo development. MATERIALS AND METHODS Sheep ovaries were collected f...

Prolonged starvation changes energy metabolism; therefore, the metabolic response to starvation is divided into three phases according to changes in glucose, lipid and protein utilisation. B-group vitamins are involved in energy metabolism via metabolism of carbohydrates, fatty acids and amino acids. To determine how changes in energy metabolism alter B-group vitamin concentrations during starv...

Background and aims: Vitamins are essential constituents of our diet that Longley have been known to influence the immune system. Vitamin D3 and B9 have received particular attention in recent years as these vitamins have been shown to have an unexpected and crucial effect on the immune response. 1, 25(OH)2D3 metabolizing enzymes and vitamin D r...

B vitamins has been recognized from the very beginning of vitamin research. Funk in 1911 first pointed out that yeast was a rich source of the beri-beri curative substance. Goldberger and Tanner (1925) introduced yeast in the treatment of pellagra. Goodall (1932) advocated its use in certain types of macrocytic ansemia. Various workers have shown that angular stomatitis and glossitis can be cur...

In 1953, the authors (1) reported that a decrease of thiamine and vitamin B12 was found in the blood as the result of the energy metabolism of cattle, and that the deficiency of the vitamins was com pletely protected against by a prophylactic injection of the vitamins at the beginning of the experiment. The intimate relation between both vitamins and metabolism was thus recognized for the forma...
