Corrosion inhibition behavior of Ascorbic acid (AA) vitamin C and Thiamine (Th) vitamin B1 on mild steel corrosion in 0.5 M HCl was investigated at various immersion times. The electrochemical characteristics of mild steel in absence and presence of the inhibitors were verified by the cyclic voltammetry method. The protective properties of the passive film were acquired by electrochemical imped...

Thiamine pyrophosphate (TPP), the biologically active form of thiamine (also known as vitamin B1), is an essential cofactor for several important enzymes involved in carbohydrate metabolism, and therefore, it is required for all living organisms. We recently found that a thiamine-binding protein (TDE_0143) is essential for the survival of Treponema denticola, an important bacterial pathogen tha...

Thiamine pyrophosphate (TPP) is the major biologically active form of thiamine (vitamin B1). This cross-sectional study assessed whole-blood thiamine pyrophosphate concentration (WBTPPC) in boarding school students in the Southern Region of Papua New Guinea. Sample size for each of the five boarding schools was calculated using the 'proportionate to population size' cluster sampling technique. ...

Thiamine (vitamin B1) is essential to the health of all living organisms and deficiency has long been associated with diseases in animals such as fish, birds, alligators, and domesticated ruminant mammals. Thiamine is also implicated in several human diseases including Alzheimer's, diabetes, dementia, depression and, most notably, Wernicke-Korsakoff syndrome and Beriberi disease. Yet, highly se...

Thiamine (vitamin B1) serves as an important cofactor in body metabolism and energy production. It is related with the biosynthesis of neurotransmitters and the production of substances used in defense against oxidant stress. Thus, a lack of thiamine affects several organ systems, in particular the cardiovascular and nervous system. The cardiac insufficiency caused by thiamine deficiency is kno...

Thiamine (vitamin B1), which is synthesized only in bacteria, fungi and plants humans should take with diet, participates basic biochemical physiological processes a versatile way its deficiency associated neurological problems accompanied by cognitive dysfunctions. The rat glioblastoma (C6) model was used, exposed to limited environment toxicity glutamate. cells were stressed exposure glutamat...

The anti-fatigue effect of dicethiamine hydrochloride (DCET) was assessed and compared to that of thiamine hydrochloride (VB(1)HCl) in rats. The absorbability and tissue distribution of thiamine after oral administration of DCET and VB(1)HCl were also examined. To create fatigued animals, male SD rats were placed in plastic cages containing 1.5cm of water for 5 consecutive days. The extent of f...

The present study examined the intestinal uptake of thiamine (vitamin B1) using the human-derived intestinal epithelial cells Caco-2 as an in vitro model system. Thiamine uptake was found to be 1) temperature and energy dependent and occurred with minimal metabolic alteration; 2) pH sensitive; 3) Na+ independent; 4) saturable as a function of concentration with an apparent Michaelis-Menten cons...

A new rumen escapable tool is presented for cattle in prospect of developing medical treatment or supplementing trace elements for disease prevention. This tool consists of a three-layered capsule that dissolves in the lower digestive tract, but not in the rumen. The capsule was manufactured by capsule-forming techniques through the use of liquid surface tension. This method does not involve hi...

To maintain normal carbohydrate metabolism in the body, we have to ingest thiamine from our diet. The daily required amounts are 1.4 mg (4.2 μmol) for men and 1.1 mg (3.3 μmol) for women for Japanese (18-29 y) , and 1.2 mg (3.6 μmol) for men and 1.1 mg (3.3 μmol) for women for U.S. people and Canadians (19-30 y). However, there were several patients who had experienced symptoms from the deficie...
