Thiamine deficiency in rats induced by oxythiamine is accompanied by an increase in the free NADP+/NADPH ratio in liver tissue, which results in multifold stimulation of the metabolite flux in the oxidation branch of the pentose cycle. The increase in the intracellular concentrations of isocitrate
Vitamin B1 deficiency in mongrel albino rats induced by oxythiamine is concomitant with an increase in the ratio of free forms of NAD+/NADH, NADP+/NADPH in liver mitochondria. This is accompanied with a rise in steady-state concentrations of isocitrate, 2-oxoglutarate and with a decrease of malate
The metabolic effects of thiamine deficiency on the metabolism of lactate, acid-base and amino acids were evaluated both with and without muscular exercise in a controlled animal experiment. Thiamine deficiency - in good correlation with its biologic halftime and also with reports in the literature
OBJECTIVE
To determine the prevalence rate of subclinical beriberi polyneuropathy (PNP) in the low income group and to present new methods for early detection.
METHODS
We conducted a prospective, randomized observational study on all patients from family members of non-PNP patients presenting to the
BACKGROUND
Thiamine status of ruminants is adversely affected in acidic rumen conditions. However, there have been limited published case study data related to thiamine deficiency of ruminants with acute ruminal lactic acidosis (ARLA).
OBJECTIVE
Thiamine deficiency would occur in sheep with
Thiamine or vitamin B(1), an essential nutrient absorbed from the diet, is involved in vital brain metabolic and cellular functions, including carbohydrate metabolism and neurotransmitter production. Diencephalic regions and, in particular, the cerebellum demonstrate lesions in cases of prolonged
A 52-year-old woman was admitted to the hospital because of appetite loss, unsteadiness, psychogenic symptoms, ataxia, and consciousness disturbance as a result of the ingestion of a diet restricted to only carbohydrates for a long term. Laboratory examination indicated the presence of pancytopenia
A 37-year-old male presented with peripheral edema of sudden onset. Other signs of heart failure were absent. Subsequent evaluation revealed that the patient was a schizophrenic whose diet consisted almost entirely of carbohydrates. A clinical diagnosis of beriberi heart disease was made and the
