aeluropus lagopoides is a salt and drought tolerant grass from poaceae family, distributed widely in arid regions. there is almost no information about the genetics or genome of this close relative of wheat that stands harsh conditions of deserts. differential display amplified fragment length polymorphism (dd-aflp) led to the improvement of a non-radioactive method for which many parameters we...

background and objectives: resistance to macrolide can be mediated by erm and msra genes in staphylococcus aureus . there are the evidences that show erm genes may be causative agent of inducible or constitutive resistance. the aim of this study was to investigate the incidence of inducible clindamycin resistance and determine the most frequency of erm and msr a genes among s. aureus isolates. ...

background: clindamycin inducible resistant staphylococcus aureus (s.aureus) isolates can cause failure in treatment with this antibiotic. biofilm production via polysaccharide intercellular adhesion (pia) contributes in the colonization of s. aureus, resulting in the initiation of different diseases. the aim of this study was to detect icaadbc genes among isolates of s.aureus with inducible re...

background and objectives: macrolide, lincosamide and streptogramin type b (mlsb) antibiotics are important in the treatment of staphylococcus aureus infections and existence of isolates with ability to resist against mlsb antibiotics is worrisome. materials and methods: in this cross sectional study, 101 s. aureus isolates were collected from patients of five selected hospitals in tehran over ...

background staphylococcus aureus is a common pathogen in hospitals and communities. antibiotic resistance is a major public health problem. objectives the aim of this study was the determination of antimicrobial susceptibility patterns and to perform molecular detection of macrolide and lincosamide-resistance genes in clinical s. aureus isolates from kerman, iran. conclusions a high prevalence ...

one of the best strategies to control bacterial wilt caused by ralstonia solanacearum (smith) is generally based on breeding resistant cultivars. the information obtained from the expression of plant defense genes will provide new insight for improving plant resistance against pathogens. this study was to identify inducible genes under defense no death (dnd) reaction of tobacco (nicotiana tabac...

conclusions the rate of imlsb in s. aureus isolates is relatively high in the northwest iran. since isolates with inducible resistance may mutate and change to constitutive resistance, to prevent clinical treatment failure, d-test should be performed along with routine antibiotic susceptibility tests. in this study, ermc gene was the predominant genetic determinant for the expression of mlsb re...

A binary vector carrying two WUSCHEL-related homeobox (WOX) genes, WOX2 and WOX8, under the control of a chemical-inducible expression system, worked in transformation N. paniculata, recalcitrant species Nicotiana. The resulting transformants exhibited improved culture performance regeneration from leaf segments suspended cells. Multicellular masses generated freely cells showed specific cell d...

Hepatoma cells derived from liver carcinoma are a candidate cell source for bioartificial (BAL) systems due to their high proliferative capacity, although function of hepatoma is considerably low compared with primary hepatocytes. In our previous study, genetically engineered mouse inducible were established by transducing liver-enriched transcription factor (LETF) genes. this we aimed develop ...
