Alpha Hydroxy Acid (AHA) / Beta Hydroxy Acid (BHA)
AHAs act on both the epidermal and the dermal levels. When applied to the skin, AHAs stimulate the exfoliation of epidermal cells in the stratum corneum (s.c.) by interfering with the ionic bonding between these cells. This results in the sloughing off dull, rough skin and promotes cellular renewal. Initially used for treatment of hyperkeratosis and other skin conditions affecting s.c. turnover...
متن کاملl-Hydroxy acid oxidase.
In previous communications (l-4) the properties and isolation of the l-amino acid oxidase of rat kidney were described. Quite accidentally, it was found that solutions of the enzyme were able to catalyze the oxidation of Z-hydroxy acids, and further study disclosed that this ability ran parallel with l-amino acid oxidase activity from the first crude extract to the final electrophoretically hom...
متن کاملMacrophage Hydroxy - Eicosatetraenoic Acid Metabolism
Mouse resident macrophages are potent sources of arachidonic acid (20:4) 1 metabolites generated via both the cyclooxygenase and lipoxygenase pathways (1-5). The phospholipids of this cell are highly enriched with 20:4, and upon appropriate membrane stimulation, up to 50% of endogenous 20:4 is released and metabolized to a mixture of prostaglandins, hydroxy-eicosatetraenoic acids (HETEs), and l...
متن کاملAcaricide Residues in Beeswax and Honey
We studied the contamination level of the acaricides Folbex VA (bromopropylate, BP), Perizin (coumaphos, CM) Apistan (fluvalinate, FV) and Bayvarol (flumethrine, FM) in brood combs, sugar feed, honey and in new beeswax. All samples were analysed by gas chromatography with ECD detection. After one normal acaricide treatment, in autumn, the brood comb wax was contaminated by all these acaraicides...
متن کاملFluvalinate Residues in Greek Honey and Beeswax
Tau-fluvalinate has been the most frequently used varroacide in Greece over the last decade. Application of the commercial apicultural product Apistan at the recommended dose does not seem to contaminate honey seriously. On the other hand, application of the nonauthorized for apicultural use, agricultural formulations, using various application techniques and doses may result in the presence of...
