background 3-4methylenedioxymethamphetamine (mdma) is a synthetic and psychoactive drug, which is known popularly as ecstasy and has toxic effects on human organs. objectives considering the potential toxic interaction, this study was performed to quantify the expression of bax and bcl2 genes in mdma-induced hepatotoxicity on rat liver. subsequently, we evaluated pentoxifylline as a possible pr...

Antimicrobial synergy resulting from antibiotic combination therapy is often important in the treatment of serious bacterial infections. Previous studies have demonstrated synergy between an aminoglycoside and beta-lactam antibiotics in the treatment of Pseudomonas aeruginosa infections. The present paper investigates the synergic effects of aminoglycosides (amikacin and netilmicin) and fluoroq...

The work presents a comparative assessment of seven different feature sets for recognition of handwritten Arabic numerals using a Multi Layer Perceptron (MLP) based classifier. The seven feature sets employed here consist of shadow features, octant centroids, longest runs, angular distances, effective spans, dynamic centers of gravity, and some of their combinations. On experimentation with a d...

Glycyrrhiza is a genus of about 20 accepted species in the legume family (Fabaceae), with a distribution in Asia, Australia, Europe, and the Americas. Recently, about 30 species from the genus Glycyrrhiza have been found and used in traditional medicine for treating cancer. Different studies confirmed that down regulation of Non-metastatic protein (NM23), a metastasis suppressor gene is related...

major inhibitory neurotransmitter receptor in the mammalian central nervous system. Functional mammalian GABARs are thought to be pentameric combinations of homologous subunits drawn from seven different families with multiple subtypes: a(1–6), b(1–3), y(1–3), d, e, π and  (Macdonald & Olsen, 1994; Davies et al. 1997; Hedblom & Kirkness, 1997; Bonnert et al. 1999). Like other members of the li...

We have examined the effects of 10 different growth factors either alone or in combination on colony-forming unit-spleen (CFU-S) and repopulating stem cell survival in vitro. Either interleukin-3 (IL-3), granulocyte-colony-stimulating factor (G-CSF), or IL-4 alone support CFU-S in vitro. The effects of IL-3 or G-CSF could be neutralized by adding antibodies against IL-3 or G-CSF, respectively. ...

The combined effects of inoculation level (4 or 8-fold compared to standard inoculation) and sequence (standard inoculation before fermentation and 3-fold inoculation at the end of fermentation=1+3, Two-fold inoculation before fermentation and the same at the end of fermentation=2+2, 2+6, 4-fold before fermentation=4, 4+4, and 8) of culture inoculum containing probiotics on biochemical and micr...
