this study describes the length-weight and length-length relationships for 28 populations of garra ruffa in different basins of iran, including tigris, karkheh, karun, persis and hormuz. the length-weight relationships from most localities are reported here for the first time. for most populations the b value was not significantly different from 3, indicating an isometric growth, in a few, it w...
Phylogenetic analysis has been widely accepted as the process by which the genetic continuity between populations of different species can be detected and therefore their genetic history traced. Such analyses have actually been based on a variety of well-recognized and defined characters. In the genus Drosophila, for example, external morphological characters, -4 internal morphological characte...
Silicosis is the most common occupational lung disease worldwide. It leads to respiratory impairment and may have associated infections that decrease pulmonary function. We describe the case of a 55-year-old man with chronic silicosis who presented with hemoptysis and a cavitated conglomerate mass. The final diagnosis was silicotuberculosis.
A stability-indicating reverse-phase high-pressure liquid chromatography method with photodiode array detector was developed and validated for estimation of riluzole in the bulk and tablet dosage forms. Riluzole was subjected to stress conditions (light, heat, humidity, acid/base hydrolysis and oxidation) and the stressed samples were analyzed by developed method. Degradation was observed in ac...
A simple and rapid stability indicating method based on capillary zone electrophoresis has been developed and validated for the analysis of buserelin (BUS). The best separations were achieved by using a bare fused silica capillary (75 μm i.d.; 65.5 cm total, 57.0 cm effective length), phosphate buffer (pH = 3.00; 26.4 mM), at 35 °C. The sample was hydrodynamically injected at 50 mbar for 5 seco...
