In this study, the fate of steroid hormones in beef cattle manure composting is evaluated. The fate of 16 steroids and metabolites was evaluated in composted manure from beef cattle administered growth promotants and from beef cattle with no steroid hormone implants. The fate of estrogens (primary detected as estrone), androgens, progesterone, and the fusarium metabolite and implant α-zearalano...

To determine the efficacy and safety of Trabectome surgery on patients with steroid response, ranging from ocular hypertension refractory to maximal medical therapy to the development of steroid-induced glaucoma.A nonrandomized, nonblinded, retrospective study of 20 subjects with steroid response was conducted. All 20 eyes underwent Trabectome surgery alone. Nine subjects had steroid response w...

BACKGROUND Prior studies associate steroid use with infection risk but were limited to select populations and short follow-up periods. The association of steroid use with long-term risk of community-acquired infections is unknown. We sought to determine the association of steroid risk with long-term risks of community- acquired infections and sepsis. METHODS We used data on 30,239 adults aged...

Human nephrotic syndrome has been related to mutations in glomerular proteins. Mutations in the NPHS2 gene that encodes podocin have been described as responsible for steroid-resistant nephrotic syndrome. It has been advised to test for NPHS2 mutations in parallel or before giving steroid treatment in nephrotic syndrome patients in order to avoid unnecessary therapy. We identified NPHS2 mutatio...

To determine if activation of the glucocorticoid receptor involves covalent charge modification of the steroid-binding protein, unactivated and activated IM-9 cell glucocorticoid receptors were examined by high resolution two-dimensional gel electrophoresis. As previously reported (Smith, A. C., and Harmon, J. M. (1985) Biochemistry 24, 4946-4951), two-dimensional electrophoresis of immunopurif...

Using renewable and biocompatible natural-based resources to construct functional biomaterials has attracted great attention in recent years. In this work, we successfully prepared a series of steroid-based cationic lipids by integrating various steroid skeletons/hydrophobes with (l-)-arginine headgroups via facile and efficient synthetic approach. The plasmid DNA (pDNA) binding affinity of the...

The mechanism of action of steroid hormones involves their interaction with tissue-specific binding sites, and results in a precise modulation of gene expression. Both high-affinity receptors and secondary binding sites exist for steroid hormones in target tissues. Only steroid-receptor complexes were, in several cases, clearly shown to directly regulate transcription by interacting with DNA re...

Steroid cell tumors of the ovary are extremely rare, accounting for only 0.1% of all ovarian tumors. Of these, steroid cell tumors, not otherwise specified (NOS) constitute about 56% of all steroid cell tumors. Most steroid cell tumors secrete steroid hormones, and only about 10% to 15% of patients are asymptomatic. The morphology of steroid cell tumors, NOS is predominantly reported to be soli...

Wittig rearrangement of 17(20)-ethylidene-16-furfuryloxy steroids 5–8 was examined. Reaction of 17E(20)-ethylidene-16afurfuryloxy steroid 5 with t-BuLi in THF afforded (20S,22S)and (20S,22R)-22-hydroxy steroids 9, 10 and 17Z(20)-ethylidene-16a-(2furyl)hydroxymethyl steroid 11 in 61, 28, and 9% yields, respectively. Base treatment of 17E(20)-ethylidene-16b-furfuryloxy steroid 7 gave (20R,22R)-22...

We studied the effect of a lipid clearing agent (clinofibrate) on the osteocytes of rabbits treated with corticosteroids. Thirty-one rabbits were divided into four groups: (A) steroid-treated with a normal diet, (B) steroid-treated and one a diet with added clinofibrate, (C) non-steroid-treated, on a diet with clinofibrate; and (D) non-steroid-treated on a normal diet. All the steroid-treated a...
