Cyproterone acetate (CPA), a synthetic progestin recently found to induce genotoxic effects in hepatocytes from female rats and from humans of both genders, and two structural analogues, chlormadinone acetate (CMA) and megestrol acetate (MGA), have been compared for their capacity to induce DNA repair synthesis as measured by quantitative autoradiography. Exposure of primary human hepatocytes f...

Background: Monotherapy is not usually effective in the treatment of hirsutism. Objective: Comparison of 2 therapeutic regimens in the treatment of hirsutism. Patients and methods: In this open parallel controlled clinical trial, 101 Patients suffering from hirsutism were randomly divided into two equal groups. 50 patients were treated with spironolactone (50 mg/day) plus cyproterone comp...

Objective. To investigate the effect of castration, bromocriptine and cyproterone acetate treatment on lysosomal hydrolytic enzymes and ultrastructure of the rat Harderian gland. Methods. Groups of rats were subjected to the treatment by bromocriptine, cyproterone acetate and castration. Harderian glands were dissected from each experimental animal, cut into small pieces and immediately stored ...

The aim of the study was to test the effect of antiandrogen, cyproterone acetate (CA) on the antler cycle in the red deer (Cervus elaphus). CA was administered to three adult red deer stags (Edward, Fuks and Gacek) in weekly intervals. Edward and Fuks were given 600 mg + 600 mg of CA, whereas Gacek was given 600 mg + 300 mg. CA was injected during the hard antler phase: in mid-October (Edward),...

Transsexualism is defined as a strong conviction of belonging to the opposite sex in individuals without any physical intersex condition. Cross-sex hormone therapy is an important component of medical treatment of transexuals but it is not exempt from adverse effects. We report a case of a meningioma in a male-to-female transsexual patient treated with estrogens and cyproterone acetate for the ...

Modified triplex-forming oligonucleotides distinguish 5-methyl cytosine from unmethylated cytosine in DNA duplexes by differences in triplex melting temperatures. The discrimination is sequence-specific; dramatic differences in stabilisation are seen for CpA methylation, whereas CpG methylation is not detected. This direct detection of DNA methylation constitutes a new approach for epigenetic a...

In this paper, we first present a new lattice-based PKE scheme on SIS, proving that it achieves CPA-security under DBi-ISIS assumption. Compared to some lattice-based schemes, ours has some advantages and is quite efficient as well as great simplicity. Similarly, we give a lattice-based PKE with multiple bits which is CPA secure under DBi-ISIS assumption. We hope that our contributions help to ...
