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...

recently, the effects of antimicrobial activity of silver nanoparticles was considered by researcher because of bacterial resistance to antimicrobial agents in chemical.the aim of this study was to evaluate the antimicrobial activity of the gold nanoparticles on escherichia coli. gold nanoparticles are chemically synthesized. standard strain of e. coli was cultured in a nutrient broth. minimum ...

Background: German chamomile (Matricaria recotita) as a medicinal plant has several therapeutic effects. Since the extract of this plant contains a high amount of α-bisabolol (Terpenoid) its antibacterial properties can be considered. Staphylococcus aureus as a pathogenic bacterium is important in clinical situations and food hygiene. So, investigation of effects of antibacterial compounds agai...

Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia. The management of the blood glucose level is a critical strategy in the control of diabetes complications. Inhibitors of carbohydrate hydrolyzing enzymes have been useful as oral hypoglycemic drugs for the control of hyperglycemia especially in patients with type II disables mellitus. The goal of the present study...

low frequency stimulation (lfs) is a potential alternative therapy for epilepsy. however, it seems that the anticonvulsant effects of lfs depend on its target sites in the brain. thus, the present study was designed to compare the anticonvulsant effects of lfs administered to amygdala, piriform cortex and substantia nigra on amygdala kindling acquisition. in control group, rats were kindled in ...

Background and objectives: Alzheimer's disease (AD) is an age dependent disorder. AD is associated with decrease of brain acetylcholine level. Nowadays, one of the methods for progression inhibition of AD is using acetylcholinesterase inhibitors. Rosaceae is a large plant family. Different biological effects of some species of this family have been reported. The aim of the present study was to ...

10-Inhibitory effects of essential oils and extracts medicinal plants on plant pathogenic fungi bacteria

In recent years, the spread of drug-resistant strains of Streptococcus pneumoniae, as the most common causes of bacterial respiratory infections, threatens public health. Therefore, the use of new antimicrobial medicines to inhibit this pathogen is an urgent demand. In this research project, the inhibitory effects of thirty recently synthesized compounds including thiazole, thiazolidine, imidaz...
