Living organisms can sense and respond to external and internal stimuli. Response isdemonstrated in many forms including modulation of gene expression profiles, motility,secretion, cell death, etc. Nevertheless, all forms share a basic property: they depend on sensingsmall changes in the concentration of an effector molecule or subtle conformational changes ina protein and invoking the appropri...

exposure to toluene can be associate with genotoxicity, neurological dysfunction, reproductive toxicity, and etc. biomonitoring of hippuric acid (ha) is used for a long time as an occupational exposure index to toluene. the aim of this study was to explore efficiency of ha as a biomarker of exposure to low level of toluene for iranian petroleum depot workers in 2011. personal monitoring to tolu...

introduction: in this study, arrangement of a low-cost optical tomography device compared to other methods such as frequency domain diffuse tomography or time domain diffuse tomography is reported. this low-cost diffuse optical imaging technique is based on the detection of light after propagation in tissue. these detected signals are applied to predict the location of in-homogeneities inside p...

methyl indole derivative of some 6-aryl-4,5-dihydropyridazin-3(2h)-ones (3a-e) were synthesized by mannich reaction and evaluated as anticonvulsant against mes (50ma, for 2sec), inh (250mg/kg), scptz (80mg/kg) and str (3mg/kg) induced convulsion methods at 50 mg/kg dose level. all compounds 3a-e were also evaluated as antitubercular agent against m. tuberculosis h37rv by maba method. all compou...

the present study evaluated the effects of different dosages herbicides oxyfluorfen and trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. in this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...

background: dengue is amongst the most serious mosquito-borne infectious disease with hot spots in tropical and subtropical parts of the world. unfortunately, no licensed vaccine for the disease is currently available in medicine markets. the only option available is the management of dengue vector mosquito, aedes aegypti (diptera: culicidae). method: predatory potential of five odonate nymphs ...
