The development of a vagina as a separate outlet of the birth canal evolves at the transition of egg laying species to eutherian mammals. The derivation of the vagina from the Wolffian and Müllerian ducts and the contribution of the urogenital sinus are still open questions. Here experiments with the complete androgen receptor defect in the testicular feminisation (Tfm) mouse are reported which...

BACKGROUND Cholestatic jaundice (CJ) in patients with sickle cell disease (SCD) poses diagnostic and therapeutic dilemmas. This is an evaluation of the role of ERCP in SCD. METHODS A total of 224 SCD patients with CJ had ERCP. The indications for ERCP were based on clinical and biochemical evidence of CJ and ultrasound findings. RESULTS The indications were: CJ only in79, CJ and dilated duc...

Increasing the turbine inlet temperature can increase the gas turbine cycle efficiency. In order to increase the turbine inlet temperature significantly, an advanced cooling system has to be essentially developed. Injection of mist to the coolant fluid is considered a promising technique to protect the hot components such as combustor liners, combustor transition pieces, and turbine vanes and b...

Two kinds of air duct cleaning methods, mechanical brushing with different brushes and compressed air cleaning, were compared in the laboratory and in newly built buildings. The ducts were contaminated either with test dust or with dust originated from a construction site. The amount of dust on the duct surface was measured with the vacuum test method and estimated visually before and after the...

BACKGROUND: In the present study, the submandibularsalivary gland microscopic morphology of the adult Africangiant pouched rat was investigated. This study was carried out toprovide the basic histology of this organ in the giant pouched rat,to accompany the dearth of information of its microscopicarchitecture in the available literature. This becomes of evenhigher importance when considering th...
