Two Cases of Hypersexuality Probably Associated with Aripiprazole

Sexual dysfunction is a common side effect in patients treated with antipsychotics but significant differences exist across different compounds. We report hypersexuality symptoms in two female patients with schizophrenia who were receiving treatment with aripiprazole. The patients experienced more frequent sexual desire and greater sexual preoccupation after taking aripiprazole. We discuss the ...

Two planetary nebulae with tori of different development ?

In this paper we discuss themorphology of two bipolar planetary nebulae (PNe) based on broad-band (ESO/SERC) and narrow-band ([O iii] and Hα) images. At first sight both objects are similar and show two pronounced bright knots – the usual signature of a torus seen edge-on. We demonstrate though that the two objects are not two of a kind at this point but are rather representing two different st...

Two Subclasses of Proto-Planetary Nebulae: Model Calculations

We use detailed radiative transfer models to investigate the differences between the Star-Obvious Low-level-Elongated proto-planetary nebulae (SOLE PPNs) and DUst-Prominent Longitudinally-EXtended proto-planetary nebulae (DUPLEX PPNs) which are two subclasses of PPNs suggested by Ueta, Meixner & Bobrowsky (2000). We select one SOLE PPN, HD 161796, and one DUPLEX PPN, IRAS 17150−3224, both of wh...

Two Planetary Nebulae in the Sagittarius Dwarf Galaxy

Two planetary nebulae are shown to belong to the Sagittarius Dwarf Galaxy, on the basis of their radial velocities. This is only the second dwarf spheroidal galaxy, after Fornax, found to contain planetary nebulae. Their existence connrms that this galaxy is at least as massive as the Fornax dwarf spheroidal which has a single planetary nebula, and suggests a mass of a few times 10 7 M. The two...
