pure and antimony doped sno2 thin films have been prepared by the sol-gel dip coating technique on glass substrate using starting material sncl2.2h2o as a host and sbcl3 as a dopant. our experimental results revealed that, the quality of the coated films on the glass depends on process parameters. the effect of annealing temperature, dipping numbers and the dopant concentration on the structura...

elastomer compound based on nr/br was prepared using different kinds of nano-zno and zno. the effect of zinc oxide as an activator of sulfur cure on the mechanical and morphological properties of the compound was studied. the result of the mechanical properties showed that the tensile strength, elongation-at-break, resilience, and abrasion resistance of the compound prepared by zno (4 phr) are ...

endo-derived nitric oxide (no) is synthesized from l-arginine by endothelium nitric oxide synthase (enos). since reduced no synthesis has been implicated in the development of coronary atherosclerosis; we hypothesized that polymorphisms of nos gene might be associated with increased susceptibility to this disorder and coronary artery disease (cad). we studied the 27 base pair tandem repeat poly...

We present a general study on a high performance supercapacitor based on intercalated reduced graphene oxide with carbon black nanoparticles. Graphene oxide sheets were synthesized by oxidation and exfoliation of natural graphite and were reduced using hydroiodic acid in the presence of carbon black nanoparticles. Graphene paper was fabricated by one-step procedure via simultaneous reducing and...

background: lithium has been the treatment of choice for bipolar disorder (bd) for many years. although erectile dysfunction is a known adverse effect of this drug, the mechanism of action by which lithium affects erectile function is still unknown. objective: the aim was to investigate the possible involvement of nitric oxide (no) in modulatory effect of lithium on penile erection (pe). we fur...

objective(s): analgesic effects of oxytocin and it's the other physiological effects were well-known. the aim of present study was determination of nitric oxide role on analgesic effects of oxytocin in mice. materials and methods: 216 male albino mice were divided randomly into two experimental groups, tail flick and formalin test. each experimental group consists of three main groups incl...

trichomoniasis, the most widespread sexually transmitted disease is caused by trichomonas vaginalis. this parasite is site specific for the genitourinary tract and recruitment of macrophages as well as polymorphonuclear nutrophils (pmn) to the site of infection is the first line of defense as a component of non-specific resistance and immunity. in this study, balb/c mice were infected with 10 i...

statement of the problem periodontal disease is a periodontal tissue inflammation caused by gram-negative and other bacteria. the release of various cytokins and mediators, including nitric oxide, in the inflammation area usually has determental effects on the periodontium, potentiating the inflammatory process. in order to prevent this side effect, investigatiors have used anti-oxidants such a...
