The in vitro antibacterial activities of garlic oil and four diallyl sulphides naturally occurring in this oil were studied against Pseudomonas aeruginosa and Klebsiella pneumoniae (total 237 clinical isolates). Garlic oil at 4 x MIC could reduce original inoculum to <or=2 log(10) in both P. aeruginosa and K. pneumoniae within 8 h. The MIC values of four diallyl sulphides against these two path...

Laser ablation in liquid was utilized to prepare a TiO2 NP suspension deionized distilled water using Q-switch Nd: YAG laser at various energies and times. The samples were characterized UV–visible absorption spectra obtained with spectrophotometer (UV-Vis,) Fourier transform infrared (FTIR), X-ray diffraction (XRD), transmission electron microscope (TEM). While, UV-Vis showed the characteristi...

background zinc oxide nanoparticles (zno nps) are known as one of the important inorganic materials used in research and health-related applications with effective antibacterial activities. although the toxic effects of zno nps have already been evaluated, more information is required to understand the possible mechanisms. objectives the aim of the present study was to determine the influences ...

Nanoparticle metal oxides represent new classes of important materials that are increasingly being developed for use in research and health-related applications. Highly ionic metal oxides are interesting not only for their wide variety of physical and chemical properties but also for their antibacterial activity. Although the in vitro antibacterial activity and efficacy of regular zinc oxides h...

This study was carried out to evaluate the antibacterial activity of aqueous and organic extracts of Thymus capitatus L. (Lamiaceae) leaves and stems. Dried ground powder leaves and stems were extracted with water (aqueous extracts), ethanol, dichloromethane and hexane (Soxhlet extracts). The antibacterial activity of these extracts was evaluated against bacteria using disc diffusion method. Th...

A novel antibacterial glass-ionomer cement has been developed. Compressive strength (CS) and S. mutans viability were used to evaluate the mechanical strength and antibacterial activity of the formed cement. Compressive yield strength (YS), modulus (M), diametral tensile strength (DTS) and flexural strength (FS) were also determined. All the formulated antibacterial cements showed a significant...

STRING FROM substituted selenobenzamides (2) a series of 2- arylselenazoles (3-7) were prepared. The antibacterial activity of compounds 3-7 against a number of microorganisms were determined. Some of these compounds showed significant antibacterial activity

Objective(s): This study considered the combination of chitosan nanoparticles with antioxidant-antibacterial fraction extracted from Lactobacillus casei and investigation of possible increasing of antibacterial activity of the fraction in hybrid nanoparticle and the effect of the fraction on the stability of chitosan nanoparticles. Methods: Extra...

Background: Despite the availability of a wide range of antibiotics, bacterial infections are among important challenges for the healthcare system. Therefore, the introduction of new antimicrobial preparations such as platelet-rich plasma (PRP) could be suggested theoretically as a preventive measure for bacterial infections. We aimed to evaluate the in vitro antibacterial activity of PRP again...
