PURPOSE Percutaneous angioplasty and stenting (PTAS) is emerging as a therapeutic option for patients with chronic mesenteric ischemia. This study evaluated patency and mortality, and their relationship between degree of vessel occlusion (stenotic or totally occluded), stent characteristics, and comorbidities in patients who were treated with PTAS of the(More)
OBJECTIVES Previous studies have shown that hyperbaric oxygen (HBO) is effective in reducing the severity of acute distal colitis (ADC). Ozone therapy (OT) reduces inflammation in several pathological conditions. We aimed to compare the effects of HBO therapy and OT in an experimental ADC rat model. MATERIALS AND METHODS Forty rats were randomly divided(More)
OBJECTIVE Overdose of acetaminophen (APAP) can lead to severe liver injury in humans and experimental animals. Pentraxin-3 (PTX-3) is produced and released by several cell types. In this study, we aimed to evaluate whether PTX-3 is a potential biomarker in the identification of APAP-induced liver injury. MATERIALS AND METHODS Thirty adult male Wistar rats(More)
OBJECTIVE Although patient preference and outcome data support continued development and use of minimally invasive endovascular therapies, only a few studies have documented radiation exposure to the patient. This report summarizes patient radiation exposure by endovascular procedure at Cleveland Clinic. METHODS A retrospective review was undertaken of(More)
BACKGROUND AND AIM Intra-abdominal adhesions are important postoperative complications following abdominal surgery. The adhesions that develop form the basis of more advanced pathology such as intestinal obstruction or infertility. Melatonin is secreted from the pineal gland in a circadian pattern; this molecule has potent antioxidant characteristics and(More)
PURPOSE The performance of atherectomy devices has been variable. The purpose of this study was to evaluate our experience using the SilverHawk atherectomy (Fox Hollow Technologies, Redwood City, Calif) device for lower extremity procedures to determine predictors of midterm success. METHODS Records of all patients who underwent lower extremity(More)
Paraquat (PQ) is a widely used herbicide. Exposure to PQ at toxic doses can result in fatal acute lung injury. Inhibition of the poly-(ADP-ribose) polymerase (PARP) enzyme alleviates inflammation and necrosis in various pathologies. Here we aimed to evaluate the effects of PARP inhibition on PQ-induced lung damage in a rat experimental model. Female(More)
Aspiration of the intra-abdominal fluid and debris is usually needed during different stages of the operation. This is necessary to protect the intra-abdominal space from contamination and/or to remove blood or tissue fluids occurring during the operation. It is also essential for obtaining a clean surgical area. Aspiration of the intra-abdominal fluid is(More)
