The ever increasing pile-up of electronic waste in dumping sites, especially in developing countries such as China, Pakistan, India and several African countries, might have caused a significant alteration in the microbial community of the contaminated sites. This change in the microbial population may have significant impact to the soil ecology function. The major pollutants of electronic wast...

priformospora indica or piri is an endophytic mycorrhiza in which its growth stimulation effect on host plant by increasing adventitious roots has been reported. the effect of piri on medicinal plant and secondary metabolite accumulation has been less studied. present study was performed in growth chamber conditions (light density 2500 lux, 16 day length and 25 °c) as a completely randomized de...

rosmarinus officinalis is one of the most important medicinal and aromatic plants around the world. essential oil as a weapon against biotic and abiotic stresses plays an important role in essential oil bearing plants. in this study the essential oil content and constituent of plants containing bacterium-gall on the shoots and crown was compared with non-contaminated plants. essential oil perce...

BACKGROUND Despite advances in surgical techniques, sterile protocols, and perioperative antibiotic regimens, surgical site infections (SSIs) remain a significant problem. We investigated the relationship between wound classification (i.e., clean, clean/contaminated, contaminated, dirty) and SSI rates in plastic surgery. METHODS We performed a retrospective review of a multi-institutional, su...

Three previous studies at Chernobyl, Ukraine, documented elevated mitochondrial DNA diversity in bank voles (Clethrionomys glareolus) from radioactively contaminated sites. Little evidence was found to link patterns of diversity in contaminated areas to radiation exposure, but the experimental design precluded discriminating among alternative explanations for elevated diversity in exposed group...

sixty sheep abomasums were randomly collected from shahrekord abattoir between april and september (2006). age and sex of the sheep were registered. all of the abomasums were transported to laboratory, nematodes, which were presented inside them, collected, and after calculating, their species and genus, were specified. abomasums that were contaminated by ostertagia or had gross damages were se...

The abundance of arsenic-tolerant diazotrophic bacteria was compared in a long-term contaminated soil versus a non-contaminated one. In addition, the characterization of tolerant diazotrophic bacteria was carried out. Differences in the number of heterotrophic N2 fixers were found between soils. Contaminated soil showed a decrease in the microbial population size of about 80%, confirming the gr...

Background: Surgical wound (site) infection is the commonest complication following laparotomy for clean-contaminated and contaminated abdominal operations. Good surgical technique and perioperative prophylactic antibiotics in clean-contaminated and contaminated abdominal operations contribute to the low rate of surgical wound infection and its complications. The objectives of this study were t...

Phytoremediation is an emerging green technology that uses plants and their associated microbes to remediate different environments contaminated with various pollutants. Phytoremediation, as an effective soil remediation technology, has gained popularity in the past ten years both in developed and developing countries. The main goal of the current article is to improve the understanding of phyt...
