Thiamine-quinone adducts. Colorimetric determination of thiamine
Experientia, 19772, 3-dichloro-1,4-naphtoquinone reacts with thiamine in the presence of NH3 to give a 1∶2 adduct, for which structureII is proposed on the basis of analytical and spectroscopic (IR) data. Such a reaction is very useful for thiamine quantitative determination.

Simultaneous excretion of thiamine and thiamine phosphates by the dog
American Journal of Physiology-Legacy Content, 1962The fate of intravenously infused thiamine phosphates was studied in the dog. The degree of dephosphorylation by blood, tissue perfusion, and by the kidney was measured. Clearance determinations showed smaller values for these substances than those for creatinine.

Starting with a brief history of beriberi and the discovery that thiamin deficiency is its cause, the symptoms and signs are reviewed. None are pathognomonic. The disease has a low mortality and a long morbidity. The appearance of the patient can be deceptive, often being mistaken for psychosomatic disease in the early stages.

After peroxynitrite addition to aqueous solutions of thiamine at neutral and alkaline pH formation of thiamine disulfide and fluorescent products was observed. The fluorescent compounds were identified as thiochrome (TChr) and oxodihydrothiochrome (ODTChr) using spectral and fluorescent methods as well as paper chromatography and mass spectrometry ...

Thiamin deficiency was long known as ‘beriberi’ in English and ‘kakké’ in Japan and China. The cause of beriberi was attributed to miasmas rising from wet soil and later to an unknown infectious organism. Systematic studies of beriberi began in the Dutch East Indies in the 1880s.

Thiamin-responsive Megaloblastic Anaemia: A Disorder of Thiamin Transport?
1984Thiamin-responsive megaloblastic anaemia (TRMA), associated with diabetes mellitus and sensorineural deafness (McKusick 24927) is a very rare disease, so far described in only five patients from four families. (Rogers et al., 1969; Viana and Carvalho, 1978; La Grutta et al., 1980; Haworth et al., 1982). We report the results of some studies carried out

Thiamine Concentration and Thiamine-destroying Activity in the Rumen of Cattle*)
Zentralblatt für Veterinärmedizin Reihe A, 2010Summary Data are presented on thiamine concentration and thiamine-destroying activity in rumen fluid. The total thiamine content ranged from about 300 to 600 nanograms per milliliter of rumen fluid, probably depending on the nature of the ingesta.

To ascertain whether thiamine HCl could be detected in beer using a double-blind triangular taste test.Three 100 ml samples of beer to which 10 or 0 mg of thiamine were added were presented in counterbalanced order to 49 volunteers. Subjects consumed and rated each sample separately for taste and appearance and chose which beer was different.Thiamine ...
