the chemiluminescence (cl) arising from the reaction of bis(2,4,6-trichlorophenyl)oxalate (tcpo) with h2o2 in the presence of a novel blue fluorescer, furandicarboxylate derivative, has been studied. the relationship between the cl intensity and concentrations of peroxyoxalate, sodium salicylate, h2o2 and furandicarboxylate derivative as fluorescer has been investigated. kinetic parameters for ...

to study the existence of clostridium septicum as probable agent associated with currently occurrence of black quarter in urmia area, sheep-dung samples were collected. the bacteriological examinations on suspicious gram positive anaerobic spore-bearing bacilli which are in clostridia genus include isolation and biochemical identification were performed. the results showed 28 different types of...

the synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(ii) complexes are described. all five compounds have the general formula [cu2(l)4(o-r)2](cl)2 or [cu2(l)2(cl)2](cl)2, in which r = ch3 or h, l=2, 3 or 4-pyridinemethanol as l2, l3 or l4, respectively. the title compounds consist of dinuclear units with bridging methoxo groups in [cu2(l4)4(o-ch3)2](cl)2, hydro...

delayed-type hypersensitivity (dth) reaction measured by skin testing is an important indicator for evaluation of cellular immune response in leishmaniasis. skin testing in leishmaniasis, known as leishmanin or montenegro test, is used normally for immunoepidemiological studies and for diagnosis. in cutaneous leishmaniasis (cl), the skin test is positive during the active phase of disease and r...

background: this study sought to assess symphyseal morphology in adolescents with different mandibular growth patterns (mgps) in order to see if a relation exists. materials and methods: in this study the symphyseal parameters (height, depth, and ratio) of normal subjects were compared with four groups with malocclusion (cl iii vertical, cl ii vertical, cl iii horizontal, and cl ii horizontal)....

introduction: the aim of the study was to investigate the effects of curcuma longa (c. longa) extract on adriamycin-induced hepatotoxicity in rat. methods: animals were divided in six groups: control (co), adriamycin (adr), adriamycin with vitamin c (adr+vitc), vitamin c (vit c), c. longa with adriamycin (cl+adr) and without adriamycin (cl-adr). hepatotoxicity was induced by adriamycin 5mg/kg a...

The relationship between the CL intensity and concentrations of peroxyoxalate, sodium salicylate, H2O2 and furandicarboxylate derivative as fluorescer has been investigated. Kinetic parameters for ...

Two polypyridyl copper(II) complexes, [Cu(phen)(phen-dione)Cl]Cl (1) and [Cu(bpy) (phen-dione)Cl]Cl (2), (where Phen =1,10-phenanthroline, bpy =2,2'-bipyridine and Phen-dione = 1,10-phenanthroline-5,6-dione), were used as efficient catalysts for the oxidation of benzyl alcohol to benzaldehyde. The effects of various parameters such as reaction temperature, reaction time, etc. were studied. The ...
