In the present study, the effect of exogenous silver nitrate (Ag+) and copper sulfate (Cu2+) applications on production of artemisinin and phenolic compounds as well as oxidative stress in the shoot cultures of Artemisia annua was investigated. A significant decrease in the shoot biomass and the total chlorophyll was observed in the shoots exposed to increased Ag concentration. Additionally, a ...

Ag/TiO2 photocatalytic nanoparticles by two methods, the sol – gel using a reducing agent and spattering was produced. Crystalline phase of Titanium dioxide was investigated in both. Ag/Tio2 peak in the sol – gel method at temperatures of 300,500 and 6000c were studied. Ag/TiO2 peak at different temperatures were determined using the spattering. XRD p...

 Background: Breast cancer is the first leading cause of cancer-related death in women. Pesticides which are excessively used in northern Iran are one of the most important risk factors for breast cancer incidence. The cytochrome P450 1A1 (cyp1A1) is a key enzyme in xenobiotics metabolism and SNPs of its coding gene has been verified to be important in cancer susceptibility. The aim of thi...

Objective(s):   Metal nanoparticles (NPs) offer a wide variety of potential applications in pharmaceutical sciences due to the unique advances in nanotechnology research. In this work, bimetal Ag-Au alloy NPs were prepared and their combinations with other antibiotics were tested against Staphylococcus aureus.   Materials and Methods: Firstly, Ag-Au alloy NPs with Au/Ag molar ratio of 1:1 was f...

Pseudomonas aeruginosa is one of the most common causes of keratitis. The current study was done to evaluate the therapeutic effects of antibacterial combinations with Silver nanoparticles (Ag-NPs) and Ciprofloxacin in experimental Pseudomonas keratitis. Sixty four New Zealand rabbits were prepared. All rabbits were randomly categorized into eight groups (each group containing eight rabbits): C...

We report on transparent ZnO/Ag/ZnO and ZnO/Ag/ZnO/Ag/ZnO thin-films were deposited on the glass substrate by RF and DC sputtering for ZnO and Ag targets, respectively. The electrical and optical properties of the single and double Low Emissivity coatings were investigated with respect to the deposition time of Ag mid layer. The visible transmittance remains about 65% for single and 45% for...
