Objective(s): In the present study, C57BL/6 female mice (n=56) were used to explore the neuroprotective effects of riboflavin in motor disability of experimental autoimmune encephalomyelitis (EAE) as a model of multiple sclerosis. Materials and Methods: The animals were assigned into 7 groups: sham-operated 1 (SO1), healthy mice receiving PBS (phosphate buffer saline); sham-operated 2 (SO2), h...

Female Wistar rats were weaned onto a diet deficient in riboflavin and compared with weight-matched and ad lib.-fed controls. The effects of riboflavin deficiency on villus morphometry and enterocyte number on the villi in the upper small intestine were studied. Riboflavin depletion was associated with increased villus length and a proportional increase in the number of cell positions along the...

There are few data on the prevalence of riboflavin deficiency in sub-Saharan Africa, and it remains unclear whether riboflavin status influences the risk for anaemia. The aims of this study were to: (1) measure the prevalence of riboflavin deficiency in children in south-central Côte d'Ivoire; (2) estimate the riboflavin content of the local diet; and (3) determine if riboflavin deficiency pred...

Brown-Vialetto-Van Laere syndrome represents a phenotypic spectrum of motor, sensory, and cranial nerve neuropathy, often with ataxia, optic atrophy and respiratory problems leading to ventilator-dependence. Loss-of-function mutations in two riboflavin transporter genes, SLC52A2 and SLC52A3, have recently been linked to Brown-Vialetto-Van Laere syndrome. However, the genetic frequency, neuropat...

1. Growth and skeletal responses to different dietary concentrations of riboflavin and biotin were compared in turkey poults from hatch to 21 d of age. The birds were fed on a turkey starter diet with different concentrations of supplementary riboflavin (0, 20 and 40 mg/kg) and biotin (0, 0.3 and 0.6 mg/kg) in a factorial design. 2. Poults fed on diets with no supplementary riboflavin had poor ...

introduction: the interest in probiotic products have been increased recently by the consumers. milk and dairy products are natural sources of b group vitamins in the human diet. this study was carried out in order to investigate the level of riboflavin (vitamin b2) and niacin (vitamin b3) in probiotic yogurt and the results were compared with the traditional yogurt during refrigerated storage....

background: faba bean toxicity (favism) is a common condition observed in our region.   objective : to develop a short and simple technique involving the use of riboflavin-deficient rats to test in vivo faba bean toxicity.   methods/results: sprague dawley rats were maintained on a riboflavin-deficient diet and their vitamin b 2 status was monitored by the assay of erythrocyte glutathione reduc...

Background: Faba bean toxicity (favism) is a common condition observed in our region. Objective: To develop a short and simple technique involving the use of riboflavin-deficient rats to test in vivo faba bean toxicity. Methods/Results: Sprague Dawley rats were maintained on a riboflavin-deficient diet and their vitamin B2 status was monitored by the assay of erythrocyte glutathione reductase (...

Riboflavin is unique among the water-soluble vitamins in that milk and dairy products make the greatest contribution to its intake in Western diets. Meat and fish are also good sources of riboflavin, and certain fruit and vegetables, especially dark-green vegetables, contain reasonably high concentrations. Biochemical signs of depletion arise within only a few days of dietary deprivation. Poor ...

Human squamous cell carcinoma has elevated levels of tetrahydrobiopterin. As the level of riboflavin is low, the ratio tetrahydrobiopterin/riboflavin shows values of 5 — 8.3. In contrast, in differentiated tissues with high metabolic activity but low mitotic rate, like submaxillary glands, elevated levels of tetrahydrobiopterin are accompanied by high content of riboflavin. Thus the ratio tetra...
