OBJECTIVE To compare the effects of oral contraceptives (OCPs) and metformin on atherogenic markers, including serum levels of advanced glycated end products (AGEs) and C-reactive protein (CRP), in lean women (Body Mass Index below 25 kg/m(2)) with polycystic ovary syndrome (PCOS), defined by NIH criteria. DESIGN Prospective open-label study. RESULTS One hundred and twenty women with PCOS w...
BACKGROUND CYP106A2 from Bacillus megaterium ATCC 13368 was first identified as a regio- and stereoselective 15β-hydroxylase of 3-oxo-∆4-steroids. Recently, it was shown that besides 3-oxo-∆4-steroids, 3-hydroxy-∆5-steroids as well as di- and triterpenes can also serve as substrates for this biocatalyst. It is highly selective towards the 15β position, but the 6β, 7α/β, 9α, 11α and 15α position...
In the field of topical application without or with little systemic side-effects to reach anti-inflammatory or anti-androgeneous effects, nanoparticles as carriers for drugs as beta-methason-17-valerate, prednicarbate, prednisolone, RU 58841-myristate or cyproterone acetate have proven to enhance the transdermal delivery. This enhancement is closely connected to the interaction of the drug mole...
BACKGROUND Cyproterone acetate combined with ethinyl estradiol (CPA/EE) provides a treatment option for women with acne, hirsutism or polycystic ovary syndrome (PCOS). CPA/EE may be prescribed as an oral contraceptive (OC), but is not licensed as such in the UK. The use of CPA/EE steadily increased after its introduction to the UK market in 1987, but there was a marked increase in its share of ...
Macrophage Fcgamma receptors (FcgammaRs) play an important role in the host defense against infection and in the pathophysiology of immune cytopenias. Modulation of macrophage FcgammaR expression is a potential therapeutic approach to immune disorders. Glucocorticoids and progesterones decrease macrophage FcgammaR expression. We assessed the effect of treatment with androgens and antiandrogens ...
Although the A/CPA has established the Professional Code of Conduct to deal with the behavior of CPAs, research has also shown that an individual's behavior is af fected by his or her personal values. While there has been considerable research of the ethical behavior of business professionals and business students, there has been limited research of the personal values of public accountants. T...
The structurally correlated dihedral angles epsilon and zeta are known for their large variability within the B-DNA backbone. We have used molecular modelling to study both energetic and mechanical features of these variations which can produce BI/BII transitions. Calculations were carried out on DNA oligomers containing either YpR or RpY dinucleotides steps within various sequence environments...
Methods for perfusing rat testis and accessory sex organs in situ by recirculating artificial medium to the hemicorpus preparation are described. The advantages and limitations of this system for studying the male reproductive tract were examined. The preparation was then used to study the uptake of androgens into the nuclei of caput epididymis, ventral prostate, seminal vesicle and testis. The...
Frog relaxin (fRLX) belongs to the relaxin/insulin gene family present in the testis of Rana esculenta and is specifically expressed by Leydig cells. Since the expression of fRLX transcript changes during the reproductive cycle and is more abundant when circulating levels of androgens are relatively high, we investigated the effect(s) of testosterone and its antagonist (cyproterone acetate, CPA...
