BACKGROUND Pyrrolidine dithiocarbamate (PDTC) is a low-molecular-weight thiol antioxidant and potent inhibitor of nuclear factor-kappaB (NF-kappaB) activation. It has been shown to attenuate harmful effects of ischemia/reperfusion (I/R) injury in many organs. In recent animal studies, destructive effects of reperfusion injury has been demonstrated. In this(More)
OBJECTIVE In the post-sternotomy mediastinitis patients, Staphylococcus aureus is the pathogenic microorganism encountered most often. In our study, we aimed to determine the efficacy of antibiotic treatment with vancomycin and tigecycline, alone or in combination with hyperbaric oxygen treatment, on bacterial elimination in experimental S. aureus(More)
BACKGROUND Mediastinitis is a dreaded complication of cardiac surgical procedures. The purpose of our study was to research the role of hyperbaric oxygen therapy (HBO) in the treatment of experimental mediastinitis and to investigate whether it potentiates the antibiotic effects of linezolid, teicoplanin, and vancomycin. METHODS The study included nine(More)
BACKGROUND Neurological injury because of transient cerebral ischemia is a potential complication of cardiovascular surgery. In this study, the neuroprotective effects of L-carnitine, vitamin E, and the combination of these agents on ischemia/reperfusion (I/R) injury were determined in a rat model of transient global cerebral I/R. METHODS Rats were(More)
BACKGROUND Abdominal aortic surgery can cause ischemic/reperfusion (I/R) injury in not only the lower extremities, but also in the remote organs and tissues such as lungs, kidneys, heart, and liver during abdominal aortic surgery. It can result in mortality and morbidity because of the remote organ injury in early postoperative period. In this study, we(More)
BACKGROUND The aim of the study was to investigate the in vivo efficacy of local and systemic antibiotic prophylaxis in the prevention of Staphylococcus (S.) epidermidis graft infection in a rat model and to evaluate the bacterial adherence to frequently used prosthetic graft materials. METHODS Graft infections were established in the subcutaneous tissue(More)
Pyrrolidine dithiocarbamate (PDTC) is a low-molecular-weight thiol antioxidant and potent inhibitor of nuclear factor-κB (NF-κB) activation. It has been shown to attenuate local harmful effects of ischemia/reperfusion (I/R) injury in many organs. In recent animal studies, a delaying effect of remote organ I/R injury on the healing of colonic anastomoses has(More)
Amaç: Bu çalışmada, abdominal aort cerrahisinde iskemi/ reperfüzyon (İ/R) sonrası uzak organ hasarı olarak akciğer üzerine silostazol, levosimendan ve bu ilaçların kombinasyonunun etkileri araştırıldı. Ça­lış­ma­ pla­nı:­Çalışma ortalama 219±26 g ağırlığında 35 erkek Wistar albino türü sıçan ile gerçekleştirildi. Sıçanlar her bir grupta yedi sıçan olacak(More)
OBJECTIVE In this study, we aimed to demonstrate whether the presence of fragmented QRS (fQRS) is associated with the frequency of premature ventricular contractions (PVCs). METHODS We retrospectively analyzed 282 cases by 24-hour Holter monitorings (HMs) between August 2012 and February 2013. Firstly, the patients were divided into 2 groups with respect(More)
OBJECTIVE Pulsatile flow, generated by a pump during cardiopulmonary bypass, has been accepted as more physiological in coronary artery bypass grafting surgery (CABG). Therefore, we aimed to investigate the effects of pulsatile and nonpulsatile flow on postoperative cognitive function and to review relationship with the biomarkers S100ß and neuron-specific(More)
