标题:Fe0还原卤代乙酸:对治疗和命运的影响.
摘要:为了预测天然或工程系统中的卤乙酸(haas)的命运,需要有关这些化合物进行的反应类型,这些反应的速率以及形成的产物的信息.鉴于许多饮用水分配系统由无衬里的铸铁管组成,Haa与元素铁(fe0)的反应可能在确定这些系统中haa的命运方面发挥了作用.此外,零价铁可能被证明是从氯化饮用水和废水中去除haas的有效处理技术.因此,分批实验用于研究四种三卤代乙酸,三氯代乙酸(tcaa),三溴代乙酸(tbaa),氯代二溴代乙酸(cdbaa)和溴代二氯代乙酸(bdcaa)与fe0的反应.所有化合物都容易与fe0反应,产物形成和随后消失的研究表明反应通过顺序氢解进行的.溴优先于氯去除,而tbaa是唯一完全脱卤为乙酸的化合物.在含氯化合物中,与fe0反应的最终产物为一氯乙酸.卤素质量平衡为95-112%,碳质量平衡为62.6-112%.三卤代乙酸降解的拟一级反应速率常数如下:Bdcaa(10.6 +/-3

摘要:The present invention relates to the use of tripeptide derivatives for tightening, firming and/or moisturizing skin. Furthermore, the invention relates to a method for stimulating the synthesis of glycosaminoglycans containing a D-glucosamine and/or N-acetyl-D-glucosamine residue and/or proteoglycans by fibroblasts and/or keratinocytes such as in particular the synthesis of Hyaluronic acid and/or of the proteoglycans Decorin and/or Lumican.

权利人:HOUEN GUNNAR; HOLM ARNE
摘要:Chemical species, particularly peptides, are synthesized by a stepwise, controlled process, in which a proteinaceous substance such as a protein is used as the synthesis substrate. The products obtained by the process can be used e.g. as vaccines against various diseases and as matrix materials or carrier molecules.

摘要:The present invention provides a method for inducing hair growth by providing beta-catenin activity to a skin cell. This may be achieved by providing a beta-catenin polypeptide, providing a beta-catenin agonist, providing a polynucleotide encoding a beta-catenin polypeptide, enhancing the de novo synthesis of beta-catenin, increasing the stability or decreasing the degradation of beta-catenin polypeptides.

权利人:HENKEL KGAA
摘要:The invention relates to an aqueous or aqueous-alcoholic extract of the blue-green algal taxon Spirulina, characterized in that it contains at least 10 wt. % magnesium in relation to the dry weight of said extract. The inventive blue-green alga extract is an efficacious component for stimulating intracellular synthesis of ATP and matrix proteins and differentiation of keratinozytes. The blue-green alga extract is used in topical preparations for cleaning and cosmetic care of the skin and hair, in addition to the production of agents for dermatological treatment of the skin.

摘要:The invention relates to the use of at least one active ingredient that is selected from the water-soluble groups: (a) allantoin; (b) salts and/or esters of gluconic acid and/or aspartic acid; (c) precursors of creatine, creatine and creatinine and their derivatives; (d) glycyrrhetinic acid or the salts and/or esters thereof; (e) D-panthenol and/or at least one active ingredient that is selected from the oil-soluble groups: (f) vitamin E acetate; (g) cholesterol; (h) derivatives of glycyrrhetinic acid, in so far as they are soluble in the oils and fats that are conventionally used in the cosmetic industry; (i) vegetable oils and fats; (j) non-saponifiable fractions of vegetable fats. Said active ingredients are used alone or in combination with one or more active ingredients from the groups (a) to (j) to produce a cosmetic and/or dermatological agent for stimulating the endogenous synthesis of barrier substances, in particular for increasing the endogenous lipid content of the skin.
