Competitive exclusion can occur in microbial communities when, for example, an inhibitor-producing strain outcompetes its competitor for an essential nutrient or produces antimicrobial compounds that its competitor is not resistant to. Here we describe a deferred growth inhibition assay, a method for assessing the ability of one bacterium to inhibit the growth of another through the production ...

Inhibitors of the PI3-kinase/AKT (protein kinase B) pathway are under investigation as anticancer and antiviral agents. The benzimidazole derivative AKT inhibitor-IV (ChemBridge 5233705) affects this pathway and exhibits potent anticancer and antiviral activity. To probe its biological activity, we synthesized AKT inhibitor-IV and 21 analogues using a novel six-step route based on ZrCl(4)-catal...

many investigations have proved relations between abo blood groups with some diseases and factor viii and von willebrand level in plasma. in this study we investigated a relation between abo blood groups and factor viii and ix inhibitors in 102 patients with haemophilia a and 48 patients with haemophilia b. the assay of inhibitor was done by bethesda method. there were no relation between abo b...

a case of a 40-year-old female, in whom a 6-meter long worm (taenia saginata) was found in stomach, is reported here. in this patient, t. saginata upward migration of the worm to the stomach, its rare phenomenon, worm mostly seen in the small intestine. this is mainly because of the high gastric acidity. in this patient, we believe proton pump inhibitor (ppi) use caused hypochlorhydria and coex...

conclusions vpa and cbz treatments caused a decrease in β-catenin and vegf levels in sw480 colon cancer cell lines. these results suggest that cbz can be considered a potential antitumor drug with potencies different from vpa. methods in the present experimental study, implemented during 2014 - 2015 in iran, after incubation of cells into 96-well plates with 5,500 cells/well, the tested drugs w...

background: hereditary angioedema (hae) is a rare autosomal dominant primary immunodeficiency with complement system defect characterized by recurrent episodes of angioedema involving the skin or mucosa of the upper respiratory and gastrointestinal tracts. objective: to characterize the clinical and laboratory data of hereditary angioedema in iran. methods: patients with probable diagnosis of a...

background: given the importance of the role of depression in predicting the outcome of cardiovascular disorders, current medications for treating depression, particularly selective serotonin reuptake inhibitors (ssris), are taken into  consideration. this study aimed to systematically review the published findings in the use of ssris and the risk for cardiac events. materials and methods: an i...

The swimming properties of an E. coli-type model bacterium are investigated by mesoscale hydrodynamic simulations, combining molecular dynamics simulations of the bacterium with the multiparticle particle collision dynamics method for the embedding fluid. The bacterium is composed of a spherocylindrical body with attached helical flagella, built up from discrete particles for an efficient coupl...
