background: breast cancer is the most common malignancy in females worldwide. several etiological factors including environmental factors have been recognized for breast cancer. epstein barr virus as a viral etiological factor has been proposed. so far, several studies have investigated the relationship between development of breast cancer and epstein barr virus, but few have been done in iran....

Flavin reductase and bacterial luciferase are believed to be coupled in the in vivo light emitting reaction. In extracts, however, they are both soluble enzymes that exhibit little or no association. Immobilized luciferase, covalently attached to Sepharose, was found to bind the soluble reductase and to exhibit activity in the coupled reaction reaction with an enhanced efficiency of electron tr...

Diolefinic antibacterial laser dye namely 1,4-Bis[2-(4-Pyridyl) Vinyl] Benzene (4PVB)have been investigated electrochemically using cyclic voltammetry, chronoamperometry, convolution and deconvolution voltammetry combined with digital simulation techniques at a platinum electrode in 0.1 mol / L Tetra Butyl Ammonium Perchlorate (TBAP) in  solvent 1,2-dichloroethane.  The diolefinic ...

Association analysis is a useful method for evaluation of significant association between molecular marker and phenotype of trait. This study was performed to evaluate association between traits related with powdery mildew resistance and molecular markers. This investigation was performed using 77 barley genotypes and AFLP markers. In phenotypic evaluation, reaction of seedlings to powdery mild...

Background: Despite its effectiveness, there are still many concerns and questions about the principles and therapeutic methods of traditional medicine (TM). In other words, in order to accept TM as a reliable health care system, its proficiency need to be declared through modern scientific research. One of the major determinants of Persian medicine (PM) which is practically utilized in disease...

the solubility of cdf2 in the mixed solvent (water(1)+ethanol(2)) with mass fraction, w1 = 0.9,was determined by using solvent evaporating method in the presence of various concentrations(0.100, 0.200, 0.300, 0.400, 0.500, 0.600, 0.800 and 1.500 mo1.1)) of naci at 25°c. the values ofsolubility and solubility product constant of cdf2 in the mixed solvent were evaluated at zero ionicstrength upon...

considering the importance of parasitic wasps in biological control of pests, a faunal study was conducted in the year 2012 on eulophid wasps (hym.: chalcidoidea) in rice fields in the east of guilan province, southern coast of caspian sea. several specimens were captured via malaise traps. the specimens were identified as aprostocetus deobensis (graham), aprostocetus mycerinus (walker), elasmu...
