Multidrug transporters are integral membrane proteins that use cellular energy to actively extrude antibiotics and other toxic compounds from cells. The multidrug/proton antiporter MdfA from Escherichia coli exchanges monovalent cationic substrates for protons with a stoichiometry of 1, meaning that it translocates only one proton per antiport cycle. This(More)

This work aimed to study the effect of guided affective imagery on the irritable bowel syndrome. A total of 15 irritable bowel syndrome patients received guided affective imagery and 19 patients served as controls. Symptom severity and irritable bowel syndrome quality of life were measured at baseline and 8 weeks. Symptom severity decreased following guided(More)
BACKGROUND Failure modes and effects analysis (FMEA) is used for the identification of potential risks in health care processes. We used a specific FMEA - based form for direct referral for colonoscopy and assessed it for procedurerelated perforations. METHODS Ten experts in endoscopy evaluated and computed the entire referral process, modes of(More)
