Silver ions are a strong antiseptic with a broad spectrum. Treatment of textiles and leather with nanosilver particles is a new idea for real clean wear. The nanometer-size particles have a large specific surface resulting in the release of silver ions in antiseptic concentration. One way to investigate nanosilver treated leather is the intrinsic fluorescence of organic material. This fluoresce...

Crocus sativus L. (saffron) is a valuable plant which is native to Iran. Saffron is the dried stigmata of the flowering part of the plant that is usually contaminated with different bacteria and fungi through production process. Antimicrobial properties of silver nanoparticles are well recognized. To survey the effects of nanosilver packaging on microbiological status of spiked, saffron samples...

Based on the increasing number of multi-drug resistant bacteria in periprosthetic infections, improvement of the antibacterial activity of commonly used biomaterials must be achieved. The broad-spectrum, high antimicrobial efficacy has made silver nanoparticles a promising new antibacterial agent. However, there is still a serious lack of knowledge concerning the impact of nanosilver on bone ce...

BACKGROUND Halomethanes are toxic and carcinogenic chemicals, which are widely used in industry. Also they can be formed during water disinfection by chlorine. Biodegradation by methylotrophs is the most important way to remove these pollutants from the environment. OBJECTIVES This study aimed to represent a simple and rapid method for quantitative study of halomethanes utilizing bacteria in ...

OBJECTIVE Polymethyl methacrylate (PMMA), widely used as a prosthodontic base, has many disadvantages, including a high thermal expansion coefficient and low thermal conductivity, a low elasticity coefficient, low impact strength and low resistance to fatigue. This study aimed to make an in vitro comparison of the thermal conductivity, compressive strength, and tensile strength of the acrylic b...

Regarding fast development of the nanotechnology and the probably of it's side effects on aquatic body organs, this study investigate the effects of nanosilver administration on histology of gill, kidney and biochemical parameters in common carp. The silver nanoparticles were synthesized in a one-step reduction process in an aqueous solution. 60 O. mykiss were obtained from a local commercial h...

Background. Elimination of bacteria from the root canal system is one of the aims of endodontic treatment; hence the incorporation of antibiotics into sealers can increase their antimicrobial efficacy. The aim of the present study was to determine the in vitro antimicrobial effects of AH26 and AH Plus sealers mixed with amoxicillin, triple antibiotic paste and nanosilver on Enterococcus faecali...

BACKGROUND & OBJECTIVES Cutaneous leishmaniasis is an infection caused by protozoan genus Leishmania. Although glucantime is commonly used for the treatment of leishmaniasis, it has some side effects including increased liver enzymes and electrocardiogram changes. In addition, the drug is expensive, the injection is painful, and research shows that resistance of parasite to glucantime is growin...

PURPOSE The currently available drug repertoire against lymphatic filariasis, a major health hazard in the developing world, is inadequate and is fraught with serious limitations. Thus, the development of an effective antifilarial strategy has become a global research thrust mandated by the World Health Organization. Nanoparticles of silver endowed with antibacterial potency are known to induce...
