objectives in this study, we explored a physical method of converting drug-resistant bacteria to drug-sensitive ones. materials and methods this is an in vitro case-control study, performed at the ionizing and non-ionizing radiation protection research center (inirprc), shiraz university of medical sciences (sums), shiraz, iran in 2014. all experiments were carried out using gram-negative bacte...
Aminur Rahman (2016): Bioremediation of Toxic Metals for Protecting Human Health and the Ecosystem. Örebro Studies in Life Science 15. Heavy metal pollutants, discharged into the ecosystem as waste by anthropogenic activities, contaminate drinking water for millions of people and animals in many regions of the world. Long term exposure to these metals, leads to several lethal diseases like canc...
Bacteria produce unique combinations of volatiles that can be used to identify the genus and species, and in many cases the strain or serovar. The ability to identify bacteria by their volatilomes has generated great expectations for rapid and non-invasive clinical tests that are able to diagnose and identify infections in situ, particularly for diagnosing lung infections via breath analysis. A...
The biocomplexity of sediment communities along a 120m transect near an arsenic-rich, shallow marine hydrothermal vent at Tutum Bay, Papua New Guinea was thoroughly examined. A count of macroand meiofaunal organisms was combined with bacterial and eukaryotic SSU rRNA gene surveys to assess biodiversity. Each site along the transect had distinct microbial communities. Near-vent sites were more s...
We have established arsenic-resistant cells I(UK) and their subclones from a human lung adenocarcinoma cell line (CL3). CL3R cells and their subclones were maintained in the presence of 4 /UMsodium arsenite. They were 6-fold more resistant than CL3 cells to arsenite. Heme oxygenase was expressed in CL3R cells and their subclones, as demonstrated by electrophoretic analysis, Northern blotting, a...
Environmental arsenic is a world-wide health issue, making it imperative for us to understand mechanisms of metalloid uptake and detoxification. The predominant intracellular form is the highly mephitic arsenite, which is detoxified by removal from cytosol. What prevents arsenite toxicity as it diffuses through cytosol to efflux systems? Although intracellular copper is regulated by metallochap...
Background and Aim: The emergence of nonfermenter bacteria that are resistant to multidrug resistant ESBL are nowadays a principal problem for hospitalized patients. The present study aimed at surveying the emergence of nonfermenter bacteria resistant to multi-drug ESBL producing isolated from patients blood samples using BACTEC 9240 automatic system in Shiraz. Materials and Methods: In ...
