Vitamin C, or ascorbic acid, has a long and multifaceted scientific history. In 1937, the Nobel Prize for Physiology and Medicine was awarded to Albert Szent-Gyorgyi'in recognition of his discoveries concerning the biological oxida- tion processes with special reference to vitamin C', and the Nobel Prize for Chemistry was shared by Sir Norman W. Haworth, who was the first to synthesize the vitamin. Vitamin C is a potent antioxidant, and this action represented the theoretical basis for various lines of investigation on this molecule in which the potential role of ascorbic acid in the...

Peroxisomes (microbodies) have a long evolutionary lifespan, but in cell biology they are still young. It is gratifying to see that most recent advances in our knowledge of peroxisomes come from quite different disciplines, ranging from molecular biology and cell biology to clinical research. The identification in terms of cDNA sequences of enzymes, the localization in terms of immuno-electron microscopy, and the cell biological aspects of the organelle biogenesis have seen substantial progress very recently. Likewise, the phenomenon of peroxisome proliferation induced by a number of drugs,...

Hepatic cells are involved in the metabolization and elimination of a variety of endogenous and exogenous substances. They mediate the uptake, processing and subsequent secretion of biliary compounds, such as various drugs or hormones, and the passage of metabolites to be released into different blood compartments. To perform vectorial passages hepatocytes show a strong polarity with sites for endocytotic processes or specific carrier molecules, and a specified system of organelles for intracellular transport and sorting, metabolization and secretion of compounds. Several aspects, e.g....

Understanding the molecular basis of complex biological processes has been a major goal of biological chemistry from early on. Inflammation is one such entity, and recent years have seen exciting progress in the under standing of molecular interactions; there has been a long way from dolor, rubor, calor, and tumor as a fundamental description of the phenomenon to current knowledge, e.g., on the control of the respiratory burst of the granulocyte, the atomic details of protease regulation, or the interaction of cytokines. We were glad to have been given the opportunity by the Gesellschaft fUr...

Named after Selene, Greek goddess of the moon, selenium (Se) has moved has moved from being thought of as a toxicant to being considered an essential nutrient with the potential to reduce cancer risk in the span of seven decades. Diversity of Selenium Functions in Health and Disease focuses on current knowledge of aspects of Se research relevant to its medical use, and particularly to chemoprevention of cancer. It covers how Se is integrated into selenoproteins, selenium compounds with individual functions and dual functions, and unexpected links to Se such as with diabetes. The...
