L’actualit e de Marc Guillaumont sur la vitamine K publi ee en 2000 dans ce journal etaitparticuli erement informative, pr ecise et concise (Guillaumont, 2000). A ce jour, elle est toujours d’actualit e, et les donn ees structurelles et m etaboliques de cet article ne seront donc pas reprises dans cette revue dont l’objectif sera de r esumer les nouvelles connaissances dans le domaine depuis ce...

The antibacterial property of silver nanoparticles (Ag-NPs) and the antioxidant activity of Vitamin E have been combined by incorporation of these two active components within polylactic acid (PLA) nanofibers via electrospinning (PLA/Ag-NP/VitaminE nanofibers). The morphological and structural characterizations of PLA/Ag-NP/VitaminE nanofibers were performed by Scanning Electron Microscopy (SEM...

Osteomalacia is a diet deficiency disease of the same category as rickets. The deficiency is principally in the fat-soluble vitamine content of the diet, though there may be a calcium deficiency at the same time. The disease may be prevented by providing a diet rich in the fat-soluble vitamine content, and may be cured by adding the same to the diet.

La connaissance de la physiologie de la vitamine D a considérablement progressé ces dernières années, la faisant passer de simple vitamine à tropisme purement phosphocalcique et osseux à celui d'hormone jouant un rôle crucial dans de nombreux mécanismes physiologiques et dont le déficit est impliqué dans plusieurs pathologies. Nous présentons, dans ce travail, l'expérience du laboratoire centra...

In 1912, one of us (C. F.) experimented with antiberi-beri vitamine to see if it could act as a coferment in alcoholic fermentation. The experiments were unsuccessful at that time, but now through the wurk of Williams,l Bachmann,% and Eddy and Stevenson3 the subject has attained new interest.. Their results seem to prove that vit.amine act,ivity can be measured by the growth of yeast cells, and...

Aim: Liver and kidney are exposed to a lot of oxidant substances that are both from exogen and endogen sources. The aim of this study was to investigate the antioxidant effects of C vitamine, Melatonine (MLT) and N-acetylcystein (NAC) in carbon tetrachlorur (CCl4) induced oxidative stress in mouse. Methods: The study involved 6 groups; control group (Group 1), CCl4 group (Group 2), CCl4 + C vit...
