Thiamine was found to be accumulated in protoplasts of Saccharomyces cerevisiae in the same manner as in intact cells, suggesting that a soluble thiamine-binding protein in periplasm may not be an essential component of the thiamine transport system of S. cerevisiae. It was also found that thiamine pyrophosphate cannot be taken up by yeast protoplasts.
Parkinson's disease (PD) is a systemic disease with motor and non-motor deficits. We recruited three patients with newly diagnosed PD. They were not under anti-Parkinson's therapy. Plasmatic thiamine was within healthy reference range. We performed the Unified Parkinson's Disease Rating Scale (UPDRS) and started a parenteral therapy with high doses of thiamine. The therapy led to a considerable...
We found that CPY production in Saccharomyces cerevisiae KS58-2D/pCY303 was increased by the addition of thiamine into the medium, while the addition of thiamine had no effect on cell growth. It became clear that the positive effect of thiamine was due to transcriptional increase, because the levels of CPYmRNA were increased according to the amount of thiamine added. Furthermore, it was suggest...
BACKGROUND Thiamine (vitamin B(1)) deficiency is associated with severe diseases such as beriberi and Wernicke encephalopathy. Although most Americans have sufficient dietary intake, thiamine deficiency is observed in the alcohol-dependent and elderly populations. Measurement of thiamine concentration in whole blood provides an assessment of vitamin B(1) status in at-risk individuals. METHOD ...
This technical note describes kinetic fluorescence as an analytical technique to quantify non-fluorescent species. The technique is applied to the determination of thiamine (vitamin B1) in solution. Fluorescence intensity is monitored as thiamine converts to fluorescent thiochrome, and a relationship is established between the rate of increase of intensity and the concentration of thiamine. The...
BACKGROUND & AIMS The prevalence of thiamine deficiency in heart failure (HF) patients has been reported to be as high as 50% in outpatient settings and has been found to be as high as 96% in the inpatient setting. Results from previous studies, however, have been inconsistent and further investigation is needed to clarify the true prevalence of thiamine deficiency in patients with chronic HF. ...
The intestinal thiamine uptake process is adaptively regulated by the level of vitamin in the diet, but the molecular mechanism involved is not fully understood. Here we used the human intestinal epithelial Caco-2 cells exposed to different levels of extracellular thiamine to delineate the molecular mechanism involved. Our results showed that maintaining Caco-2 cells in a thiamine-deficient med...
Ecophysiological stimulators directly affect root morphology, especially in the embryonic stage. To enhance crop germination, an understanding of traits under abiotic inducers is needed. In this study, combined impacts white and red-blue light spectrums, cold stratification, seed fortification involving various concentrations bioactive chemicals namely simple nutrient addition program solution,...
Autism spectrum disorders are a group of neuro-developmental conditions characterized by varying degrees of language impairment, including verbal and non-verbal communication, impaired social skill, and repetitive behaviors. In this paper, we review the evidence for an association between autism and thiamine. A relationship between thiamine status and the development of autism has been establis...
Thiamine Responsive megaloblastic anemia in DIDMOA (Wolfram) syndrome has an autosomal- recessive mode of inheritance . Megaloblastic anemia and sideroblastic anemia is accompanied by diabetes insipidus (DI), diabetes mellitus (DM) ,optic atrophy (OA) and deafness (D). Neutropenia and thrombocytopenia are also present. We report a 7 month old girl with congenital macrocytic anemia a rare clin...
