Case Report A married woman, 52 years old, first seen September 1, 1948, was complaining of epiphora and a slight irritation of both eyes, particularly the right, with some photophobia. The illness was of some three months' duration, though she said she had had recurrent attacks of " sore eyes " for many years. The present attack seemed to have started after a long traip journey. The visual acu...

Since this symposium is concerned with enzymes in medicine, I shall consider only the work that has been done in human malnutrition. It would be impossible to deal with the very large literature on enzyme changes in animals under different dietary conditions. I shall also confine myself to work which is related to protein and calorie deficiency because this is the field with which I am familiar...

Many children suffer from nutritional deficiencies that may negatively affect their academic performance. This cluster-randomized controlled trial aimed to test the effects of micronutrient-fortified milk in Chinese students. Participants received either micronutrient-fortified (n = 177) or unfortified (n = 183) milk for six months. Academic performance, motivation, and learning strategies were...

introduction: it is generally assumed that 50% of the cases of anemia are due to iron deficiency. the most severe consequence of iron depletion is iron deficiency anemia (ida), and it is still considered the most common nutrition deficiency worldwide. the main risk factors for ida include: inadequate iron intake, impaired absorption or transport, physiologic losses associated with chronological...

The acetylation reaction involving detoxification of various aromatic amines both in vitro and in viva has become of new importance with the discovery by Lipmann et al. (1) that the coenzyme necessary for this coupling contains pantothenic acid. In an earlier paper (2), we gave evidence demonstrating that pantothenic acid is necessary for normal acetylation of p-aminobenzoic acid (PAB) by rats....

, Chilean population have paid little attention to the problems deriving from inadequate intake \ of vitamins. This is due to a number of factors: in the first place, the impact of vitamin deficiency on morbidity and mortality in the population is slight; secondly, since 1955 a program has been under way, and has already I been found to be effective, for enriching bread with thiamine, riboflavi...

riboflavin and protoporphyrin ix are two molecules that participate in oxidation and reduction reactions in the living cell. changing some functional groups of riboflavin and protoporphyrin ix can provide compounds with self-assembled monolayer properties with wide applications in designing the molecular electronic devices. in this study, the amphiphilic structure of riboflavin and protoporphyr...

Riboflavin, the precursor for the cofactors flavin mononucleotide (FMN) and flavin adenine dinucleotide, is an essential metabolite in all organisms. While the functions for de novo riboflavin biosynthesis and riboflavin import may coexist in bacteria, the extent of this co-occurrence is undetermined. The RibM, RibN, RfuABCD and the energy-coupling factor-RibU bacterial riboflavin transporters ...
