The adsorption characteristics of riboflavin onto silver-deposited iron oxide magnetic nanoparticles (Ag/Fe3O4) have been described. Characterization of the synthesized Ag/Fe3O4 nanoparticles was achieved by FTIR spectra, TEM image and XRD pattern. The influence of several experimental parameters such as nanoparticles dosage, pH of the sample solution...

Experiments are reported upon young rhesus monkeys which were given a diet essentially the same as the Goldberger black tongue-producing diet, supplemented in various ways. Those receiving the unsupplemented diet developed the syndrome characterized by leucopenia, anemia, gingivitis, diarrhea, and death, which has been previously described in monkeys receiving our diet of refined foodstuffs. An...

The effects of dietary deficiencies on the blood pressure of rats were studied, with especial reference to vitamin B deficiencies. A deficiency of the entire vitamin B complex was followed by a slight fall in blood pressure. A deficiency of only thse heat-stable fractions was followed by a significant and persistent rise in pressure, which could be reversed by restoring these factors to the die...

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 protopor...
