the rose sawfly, arge rosae linnaeus, is one of the most destructive pests of rose bushes in the north of iran. nowadays, many attempts have been made to reduce pesticide application by looking for new methods of pest control. a non chemical method for controlling insect pests including a. rosae can be achieved by using genetically engineered plants expressing carbohydrase inhibitors. therefore...

pseudomonas aeruginosa is among the most important pathogens in the nosocomial infections. a genetic mobile element, the integron, is one of the major agents involved in dissemination of multi-drug resistance among gram negative bacteria. during a descriptive study from october 2009 to august 2010, some 130 p. aeruginosa clinical isolates were collected from different wards of three hospitals i...

background :   ampc beta lactamases play a significant role in creating resistance to third generation cephalosporins worldwide. they mostly express on chromosome of enterobacteriaceae especially escherichia coli and cause consequential problem in clinical treatment and lead to failure in diagnosis and phenotypic test recommended by clinical and laboratory standards institute.   methods : total...

The loss or dysfunction of the pancreatic endocrine β-cell results in diabetes. Recent innovative therapeutic approaches for diabetes aim to induce β-cell proliferation in vivo by pharmacological intervention. Based on the finding that overexpression of the transcription factor Nkx6.1 in islets in vitro increases β-cell proliferation while maintaining β-cell function, Nkx6.1 has been proposed a...
