background: in this study, the toxicity of the different xenobiotics was tested on the fruit fly drosophila melanogaster model system.  methods: fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mm), s-nitrosoglutathione (0.5-4 mm), and potassium ferrocyanide (1 mm)). emergence of flies, food intake by larvae, and pupation hei...

This study evaluated bone distracted in rabbit mandibles at different intervals and with different daily rates of distraction histologically with the goal of attaining a universally accepted distraction protocol. Osteogenesis was investigated in mandibles distracted at different rates in 24 New Zealand rabbits using a custom-made submerged distractor. Distraction was started on the third postop...

A simple, rapid and sensitive high-performance liquid chromatographic (HPLC) method for the determination of risperidone in human plasma was developed. An HPLC system based on a Nucleosil C8 column (150?4 mm) and a UV detector (?= 280 nm) were used. A mixture of sodium dihydrogen phosphate buffer-acetonitrile (55:45, v/v) adjusted to pH 6.0 at a flow rate of 1.5 ml min-1 was used as mobile phas...

In the middle of the breeding season, 16 pony mares (n = 4 per day) were slaughtered on four different days (days 6, 14, 17 and the preovulatory day) of the oestrous cycle, day 0 being the day of the last ovulation. All the ovaries were examined histologically; the number, size and atresia (defined by granulosa cell pyknosis) of all follicles larger than 1 mm in diameter were studied, using a K...

We have searched for molecular absorption lines at millimeter wavelengths in eleven gravitational lens systems discovered in the JVAS/CLASS surveys of flat spectrum radio sources. Spectra of only one source 1030+074 were obtained in the 3-, 2and 1.3-millimeter band at the frequencies corresponding to common molecular transitions of CO and HCO as continuum emission was not found in any of the ot...
