Thiamin(e), also known as vitamin B1, is now known to play a fundamental role in energy metabolism. Its discovery followed from the original early research on the 'anti-beriberi factor' found in rice polishings. After its synthesis in 1936, it led to many years of research to find its action in treating beriberi, a lethal scourge known for thousands of years, particularly in cultures dependent ...

Background: Vitamin B1 (Thiamine) functions as a pyruvate dehydrogenase cofactor to produce acetyl Co-A and activate the Krebs cycle in cellular metabolism. The hypermetabolic state septic condition requires excess thiamin keep functioning well. level blood decreases causes mitochondrial dysfunction vice versa results an increase lactate levels. This study aims evaluate correlation of thiamine ...

The purpose of this study was to examine the effect of high-intensity physical activity during training on the biochemical status of thiamin and riboflavin in athletes. Thiamin and riboflavin concentrations in whole blood of a group of 19 athletes (6 men and 13 women) were measured during a low-intensity preparatory period and compared with measurements taken during a high-intensity training pe...

This review highlights recent research on the properties and functions of the enzyme transketolase, which requires thiamin diphosphate and a divalent metal ion for its activity. The transketolase-catalysed reaction is part of the pentose phosphate pathway, where transketolase appears to control the non-oxidative branch of this pathway, although the overall flux of labelled substrates remains co...

T paper in this issue of PNAS by Miranda-Rios et al. (1) demonstrates the importance of a conserved RNA structure in the regulation of genes involved in thiamin biosynthesis. Thiamin, also known as vitamin B1, is a cofactor for many important enzymes and therefore essential for growth. Bacteria have genes for all the enzymes necessary to synthesize thiamin, but if adequate amounts are present i...

The aim of this study was to investigate expression and relative contribution of human thiamin transporter (hTHTR)-2 toward overall carrier-mediated thiamin uptake by human intestinal epithelial cells. Northern blot analysis showed that the message of the hTHTR-2 is expressed along the native human gastrointestinal tract with highest expression being in the proximal part of small intestine. hTH...

Infection with the gram-negative enteropathogenic Escherichia coli (EPEC), a food-borne pathogen, represents a significant risk to human health. Whereas diarrhea is a major consequence of this infection, malnutrition also occurs especially in severe and prolonged cases, which may aggravate the health status of the infected hosts. Here we examined the effect of EPEC infection on the intestinal u...

Micronutrient deficiencies occur frequently in refugee and displaced populations. These deficiency diseases include, in addition to the most common Fe and vitamin A deficiencies, scurvy (vitamin C deficiency), pellagra (niacin and/or tryptophan deficiency) and beriberi (thiamin deficiency), which are not seen frequently in non-emergency-affected populations. The main causes of the outbreaks hav...

A significant part of a complete dairy feeding program is the mineral-vitamin component. Physiologically, minerals are involved in reproduction, lactation, cow/calf health during pregnancy and cow recovery after calving general herd health. Highly productive animals have much greater needs for vitamins than low-producing.Concentrations andvitamins feeds can be extremely variable. Dairy commonly...
