Objective PCOS is the most frequent female endocrine disorder, affecting 5%-10% of women, is characterized by hyperandrogenism, oligo-/anovulation, and polycystic ovaries. The aim of the present research is to evaluate the expression of steroidogenic acute regulatory protein (StAR) and CYP19 (aromatase) mRNA in the ovary of EV-induced PCOS rat model and the effect of the treadmill and running w...

We develop a new analytic solution for the steady-state structure of a thin accretion disc under the influence of a magnetic field that is anchored to the central star. The solution takes a form similar to that of Shakura and Sunyaev and tends to their solution as the magnetic moment of the star tends to zero. As well as the Kramer’s law case, we obtain a solution for a general opacity. The eff...

We have made a line identification list and derived preliminary abundances for the extreme peculiar star HD 101065 (Przybylski’s star), based on a spectrum recorded at ESO with the CASPEC spectrograph. The line list covers the range 5445–6587 Å. We find iron to be mildly deficient, possibly not as much as an order of magnitude, while the lanthanide rare earths are enhanced by some 4 dex. Abunda...

We discuss the identification of sources detected by the Infrared Space Observatory (ISO) at 6.7 and 15 11m in the Hubble Deep Field (HDF) region. We conservatively associate ISO sources with objects in existing optical and near-infrared HDF catalogues using the likelihood ratio method, confirming these results (and, in one case, clarifying them) with independent visual searches. We find 15 ISO...

We report the discovery of a flaring X-ray source with an optical counterpart with Hα emission and red-excess, in the direction of the SMC. A 100 ksec X-ray observation with Chandra detected a flare lasting ∼6 ksec in the source CXO J005428.9-723107. The X-ray spectrum during the flare was consistent with a thermal plasma of temperature kT=2.5±0.4 keV. In quiescence following the flare the spec...
