摘要:This invention provides a method for detecting in a sample an enzyme which catalyzes the synthesis of a double-stranded nucleic acid molecule from a nucleic acid template which comprises contacting the sample with a suitable fluorophore which selectively binds to double-stranded DNA. Also provided is a method for determining in a sample the activity of such an enzyme. This invention also provides a method for detecting an RNA-DNA heteroduplex in a sample which comprises contacting the sample with a suitable fluorophore which selectively binds to double-stranded DNA. This method for detecting an RNA-DNA heteroduplex may further comprise quantitatively determining detected RNA-DNA heteroduplex. This invention also provides a method for detecting in a sample en enzyme which catalyzes the synthesis of and RNA-DNA heteroduplex from a nucleic acid template, as well as a method of detecting the activity of such an enzyme in a sample. This invention further provides a method for detecting the viral load of HIV in a sample. Also provided is a method for diagnosing an HIV infection in a subject, and for monitoring the progression of an HIV infection in a subject. Also provided is a method for determining the viral load of HIV in a subject infected with HIV. This invention further provides a method for identifying whether a substance inhibits reverse transcriptase. Finally, this invention provides a kit for assaying an enzyme which catalyzes the synthesis of a double-stranded nucleic acid molecule from a nucleic acid template.

标题 :Methods and compositions for enhancing collagen and proteoglycan synthesis in the skin
发明人：NIMNI MARCEL; HAN BO
权利人:NIMNI MARCEL; HAN BO
摘要:A composition for application to the skin can stimulate the in vivo synthesis of collagen and proteoglycans and improve the appearance of the skin, increasing its elasticity and fullness. In general, a composition according to the present invention comprises: (1) an antioxidant compound in a quantity sufficient to enhance collagen synthesis in the skin; (2) an organic penetrant in which the antioxidant compound is soluble in a sufficient quantity that a concentration of the antioxidant compound sufficient to enhance collagen synthesis can be applied topically and penetrate the skin; (3) a mixture of essential amino acids; (4) a supplemental source of sulfur; and (5) a topical pharmaceutically acceptable carrier. The antioxidant compound can be lipoic acid, a lipoic acid analogue or derivative, a bioflavonoid, a constituent of ginkgo, or an isoflavone. The organic penetrant is preferably benzyl alcohol. Other ingredients, such as esters of tocopherol and ascorbic acid, can be included.
