A long-standing and fundamental question in biology is how genes influence complex phenotypes. Combining near-isogenic line mapping with genome expression profiling offers a unique opportunity for exploring the functional relationship between genotype and phenotype and for generating candidate genes for future study. We used a whole-genome microarray produced with ink-jet technology to measure ...

Silver nucleation on gold has been exploited for signal amplification and has found application in several qualitative and quantitative bio-sensing techniques, thanks to the simplicity of the method and the high sensitivity achieved. Very recently, this technique has been tentatively applied to improve the performance of gold-based immunoassays. In this work, the exploitation of the signal ampl...

objectives: in present study we aimed to clone the lux i gene encoding n-acyl-homoserine synthase detected in biofilm forming clinical isolates of acinetobacter baumannii and study its expression in escherichia coli transformants. materials and methods: four a. baumannii hospital strains which demonstrated strong biofilm activity were selected in this investigation. the presence of lux i gene w...

sodium/proton exchangers (nhx) are key players in plant responses to salinity and have a central role in establishing ion homeostasis. nhxs can be localized in tonoplast or plasma membranes, where they exchange sodium ions for protons, resulting in the removal of ions from the cytosol into vacuole or extracellular spaces. in the present study, the expression pattern of the gene encoding na+/h+ ...

increment. it is categorized based on genetic aberrations. some of these genetic disorders can determine minimal residual diseases (mrd) and prognosis of aml patients. wilms tumor (wt1) over expression is found in aml patients. the aim of this study was to determine the frequency of wt1 over expression in aml pediatric cases in north -east of iran. materials and methods: this retrospective stud...

introduction: calcium/calmodulin-dependent protein kinase ii (camkii) is highly expressed in the hippocampus, which has a pivotal role in reward-related memories and morphine dependence. methods: in the present study, morphine tolerance was induced in male wistar rats by 7 days repeated morphine injections once daily, and then gene expression profile of α-isoform of camkii (camkiiα) in the hipp...
