the antimicrobial effect of metal nanoparticles such as zinc oxide and silver nanoparticles has been taken into great consideration separately during recent years. the useful application of these nanoparticles in the areas of medicine, biotechnology, and professional prevention of microbes motivated us. the aim of this study was to evaluate antibacterial activity properties of silver doped zinc...

background preterm premature rupture of membrane (pprom) prior to 37 weeks’ gestation is among the most common obstetrics problems, which is associated with prenatal mortality and several maternal and neonatal complications. history of pprom is a risk factor for recurrence. zinc has an important effect on the strength of membranes by affecting collagen [tensile] strength - a substance with immu...

Background: Oligoasthenospermia (OAS) is a condition characterized by low sperm count associated with low sperm motility. Medical treatment is not known in allopathic system for treatment of oligoasthenospermia. Homeopathic medicine is effective in more than 95% patients. Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology...

in order to study the effect of vermicompost containing copper oxide and zinc oxide nanoparticles on was beans, in an experiment factorial were done based on a randomized complete block design in three replications. the experiment treatment were as follows: nanoparticles in 4 levels (0, 0.4, 0.8 and 1.2 g/kg weight of substrate), vermicompost in 3 levels (2.5, 5 and 7.5 g/kg-1 weight of substra...

Zinc metal nanoparticles in picomolar concentrations strongly enhance odorant responses of olfactory sensory neurons. One- to 2-nm metallic particles contain 40-300 zinc metal atoms, which are not in an ionic state. We exposed rat olfactory epithelium to metal nanoparticles and measured odorant responses by electroolfactogram and whole-cell patch clamp. A small amount of zinc nanoparticles adde...

electrosynthesis process has been used for preparation of zinc sulfide nanoparticles. zinc sulfide nanoparticles in different size and shapes were electrodeposited by electrolysis of zinc plate as anode in sodium sulfide solution. effects of several reaction variables, such as electrolysis voltage, sulfide ion concentration as reactant, stirring rate of electrolyte solution and temperature on p...

BACKGROUND Antibiotic resistant bacteria can be considered as a main problem in infection management. Zinc oxide nanoparticles (ZnO NPs), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. METHODS In this study, Zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

in this research, the inhibitory effects of silver nanoparticles and zinc oxide nanoparticles,  in vitro, on disease stone fruits bacterial canker caused by pseudomonas syrigae pv. syringae and disease bacterial blight caused by xanthomonas arboricola pv. juglandis, were studied. different concentrations of nanoparticles were prepared on mueller hinton agar medium in two different ways in a com...

Zinc phosphate (Zn3(PO4)2) nanoparticles were successfully prepared by precipitation method using zinc acetate and Phosphoric acid as the zinc and phosphate sources. The synthesized Zn3(PO4)2 nanoparticles were characterized by X-ray diffraction, Scanning electron microscope and Transmission electron microscope in order to confirm the phase purity and morphology of the sample. Zn3(PO4)2 nanopar...
