Fluorides - mode of action and recommendations for use.
Various authors have shown that the caries decline in the industrialized countries during recent decades is based on the use of fluorides, of which local fluoride application in the form of fluoridated toothpastes is of primary importance. The caries-protective potential of fluorapatite is quite low; in contrast, dissolved fluorides in the vicinity of enamel are effective both in promoting remi...
متن کاملBiological action of mycotoxins.
Mycotoxins are ubiquitous, mold-produced toxins that contaminate a wide variety of foods and feeds. Ingestion of mycotoxins cause a range of toxic responses, from acute toxicity to long-term or chronic health disorders. Some mycotoxins have caused outbreaks of human toxicoses, and at least one mycotoxin, aflatoxin B1, is a presumed human hepatocarcinogen. As part of a comprehensive effort to cu...
متن کاملOn the Physiological and Medicinal Action of Hydrofluoric Acid and the Fluorides
Resident Physician, Medical College Hospital, Calcutta. As hydrofluoric acid has lately been used with apparent success in the treatment of goitre (E. Woakes in Lancet, p. 448, vol. I., 1881); and still more recently a fluorine salt?the ammonium fluoride has gained in Calcutta (Dr. Coates in p. 26 of Indian Medical Gazette for current year) not a little reputation for the discussion of enlarged...
متن کاملEfficient synthesis of aryl fluorides.
Selective functionalization reactions of aromatic and heteroaromatic halides with carbon, oxygen, and nitrogen nucleophiles have attracted much attention in the last decades. In addition to typical metal-catalyzed coupling reactions, direct functionalization of aryl halides through the formation of Grignard reagents offer new ways for the efficient construction of biologically interesting carbo...
متن کاملFluorides and oral health.
The discovery during the first half of the 20th century of the link between natural fluoride, adjusted fluoride levels in drinking water and reduced dental caries prevalence proved to be a stimulus for worldwide on-going research into the role of fluoride in improving oral health. Epidemiological studies of fluoridation programmes have confirmed their safety and their effectiveness in controlli...
