Detection of designer steroids
Illicit use of performance-enhancing steroids has proliferated among a wide range of professional and amateur athletes. This problem has attracted broad public attention and has led the United States Congress to draft legislation that proposes frequent testing of athletes. However, current testing protocols are inadequate as athletes can evade detection by using novel steroids that are unknown ...
متن کاملBiological aromatization of steroids.
The conversion of androgenic steroids to the phenolic estrogens by mammalian tissue has been well documented. The reaction has been reported in relatively low yield, in vitro with ovarian and placental slices (l-3), and in viva after the administration of androgens to various species including man (4, 5). The present report describes the conversion of androgens to estrogens in high yield by a s...
متن کاملPaper Chromatography of Steroids
In Paper I of this series (1) a method was described for the paper chromatographic analysis of certain ketonic steroids as hydrazones formed with Girard’s Reagent T. When that technique was applied to the adrenal cortical hormones, however, certain deficiencies appeared. (a) The RI values of the individual steroid-Reagent T hydrazones were not sufficiently different to permit identification. (b...
متن کاملUrinary Steroids of Cats
Adrenal steroid secretion by cats has been studied by Bush (1951, 1953) and reviewed by Dorfman (1959). The cat adrenal secretes both cortisol and corticosterone. Arteta & Borrell (1958) and Borrell (1958) have reported studies of urinary excretion of 17-hydroxy corticosteroids (PorterSilber chromogens). Cats appear to excrete in urine very low concentrations of 17-hydroxy corticosteroids, all ...

significant information in a given field and interpret it in terms of our current knowledge of the rapidly expanding research findings within the life sciences." The preceding publisher's statement is quoted because Dr. Sutton has so admirably carried out his mission. Genes are presented as functional units; specific examples of their fine structure are described with emphasis on their relation...
