bankruptcy anticipation is a phenomenon which has been increasingly favored by investors, banks and financial and credit institutes. since the potential signs of bankruptcy would be understood a few months before the real appearance of it, so the timely and accurate anticipation of this crisis will give the opportunity to managers and creditors in order to adopt preventable activities. the aim ...

some 190 specimens of sefidrud loach, oxynoemacheilus bergianus , were collected from aras river (northwestern iran) and age, size, and some biological characteristics of the samples were investigated from march to july 2013. the maximum age was 3 + years. the specimens ranged in size from 42 to 64mm for males and 45 to 61mm for females in total length, weighing from 0.62 to 2.03g for males and...

background: abnormal patellar height is associated with anterior knee pain and several conditions that affect the patellofemoral joint. the aim of this study was to 1) report the incidence of patella alta and patella baja and 2) investigate whether the normal limits of the insall-salvati ratio is applicable in adult middle-easterners. methods: a radiographic review of the lateral radiographs of...

background: we investigated whether the lungheart ratio parameter (lhr) can be used to identify the optimum cut off frequency for butterworth filter in 99mtc myocardial spect imaging. materials and methods: this study involved a cardiac phantom system consisting of cardiac insert in which 1.10 cm cold defect was inserted into its myocardium wall and filled with 4.0 μci/ml (0.148 mbq/ml) 99mtc c...

To investigate the role of AP-1 transcription factors in mediating retinoid-induced growth suppression of breast cells, we studied the sensi tivity of MCF7 breast cancer cells with different levels of AP-1 activity to all-frans retinole acid (atRA). AP-1 activity was increased in MCF7 cells by stably transfecting c-jun cDNA into these cells. Parental and vectortransfected MCF7 cells, which were...

The effect of prolonged UV irradiation (mostly 2537 A) on the catalase activity of an aqueous yeast suspension was divisible into 4 periods. First, the period during which the cells lost their ability to form colonies, but during which no change in catalase activity was noted. Second, the period during which a considerable rise in catalase activity (Euler effect) occurred. The Euler effect was ...

BACKGROUND & OBJECTIVES Plasmodium falciparum is the leading cause of mortality and causes cerebral malaria associated with sequestration caused by cytoadherence of the trophozoite and schizont-infected erythrocytes to the endothelial cells of the deep vascular beds in the brain. Pathophysiology of malaria is complicated by rosetting. Rosetting is a process of binding of uninfected erythrocytes...

Following a recent demonstration that H,K-ATPase can active transport Na+ at a low rate (Polvani, C., Sachs, G., and Blostein, R. (1989) J. Biol. Chem. 264, 17854-17859), we have looked for and found effects of Na+ ions on the conformational state of gastric H,K-ATPase labeled with fluorescein isothiocyanate. Na+ ions reverse the K(+)-induced quench of the fluorescein fluorescence and somewhat ...
