In vitro analysis of urinary uranium of cancerous patients in Dhi_Qar governorate, southern Iraq.

The simple and effective technique of fission track etch has been applied to determine trace concentration of uranium in human urine samples taken from two groups of male and female participants: cancer patients and healthy subjects are living in Dhi-Qar governorate, southern of Iraq. This governorate was the center of industrialization and the prior military activities especially during the Gulf wars in 1991 and 2003, and the abandoned weaponry is still present in these regions. The induced fission track registration was done using the CR-39 track detector.

The use of combination therapy for the improvement of colistin activity against bacterial biofilm.

Colistin is used as a last resort for the management of infections caused by multi-drug resistant (MDR) bacteria. However, the use of this antibiotic could lead to different side effects, such as nephrotoxicity, in most patients, and the high prevalence of colistin-resistant strains restricts the use of colistin in the clinical setting. Additionally, colistin could induce resistance through the increased formation of biofilm; biofilm-embedded cells are highly resistant to antibiotics, and as with other antibiotics, colistin is impaired by bacteria in the biofilm community.
