Bacillus flexus strain As-12, a new arsenic transformer bacterium isolated from contaminated water resources.

A total of 14 arsenic-resistant bacteria were isolated from an arsenic-contaminated travertine spring water in the central district of Qorveh county, Kurdistan Province, Iran. One of strains designated As-12 was selected for further investigation because of its ability to transform arsenic. The strain was identified by cultural, morphological and biochemical tests, and 16S rRNA gene sequencing.

Right ventricular myxoma originating from a papillary muscle: a case report.

Very few cases of ventricular myxoma originate from a papillary muscle. Patients with a cardiac myxoma and a history of colorectal carcinoma are also rare. Here, we present a case of an extremely large right ventricular myxoma that originated from the posteromedial papillary muscle in a patient with a history of colorectal carcinoma.

Evaluation of the effects of ischemic preconditioning with a short reperfusion phase on patients undergoing a coronary artery bypass graft.

Purpose: This study was conducted to evaluate the effects of ischemic preconditioning (IP) with a short period of reperfusion (2 min) during brief ischemic preconditioning (6 min) on patients undergoing coronary artery bypass grafting (CABG).

Methods: In a randomized controlled trial, 40 patients undergoing on-pump CABG with cold blood cardioplegia were allocated into two groups, one IP and one control. IP was induced by 2 cycles of ascending aorta clamping (2 min for each) followed by two reperfusion phases (1 min for each).

Effect of milrinone on short-term outcome of patients with myocardial dysfunction undergoing coronary artery bypass graft: A randomized controlled trial.

Background: Myocardial dysfunction needing inotropic support is a typical complication after on-pump cardiac surgery. In this study, we evaluate the effect of milrinone on patients with ventricular dysfunction undergoing coronary artery bypass graft (CABG).

Methods: Seventy patients with impaired left ventricular function [left ventricular ejection fraction (LVEF) < 35%] undergoing on-pump CABG were enrolled.

The association between Chlamydia pneumoniae DNA in arherosclerotic plaque and major risk factors in patients undergoing coronary artery bypass grafting.

Background And Aim: This study was conducted to investigate the prevalence of Chlamydia pneumoniae pathogen inside the atherosclerotic plaque of patients undergoing CABG by using PCR assay and to determine whether there is any association between the presence of bacteria in atherosclerotic lesions and classical coronary risk factors.

Methods: In a cross-sectional study, 102 patients (20 to 79 years old; 73.5% male) undergoing CABG were evaluated in terms of major coronary risk factors and the presence of Chlamydia pneumoniae.
