Automatic program repair papers tend to repeatedly use the same benchmarks. This poses a threat external validity of findings research community. In this paper, we perform an empirical study automatic on benchmark bugs called QuixBugs, which has been little studied. (1) We report characteristics QuixBugs; (2) effectiveness 10 tools it; (3) apply three patch correctness assessment techniques com...

Mammalian mitochondria contain several 16.5 kb circular DNAs (mtDNA) encoding electron transport chain proteins. Reactive oxygen species formed as byproducts from oxidative phosphorylation in these organelles can cause oxidative deamination of cytosine and lead to uracil in mtDNA. Upon mtDNA replication, these lesions, if unrepaired, can lead to mutations. Until recently, it was thought that th...

We encountered a very rare lesion, which included a dissection between a prosthetic patch for repair of an incomplete atrio-ventricular septal defect (AVSD) and a pseudo-intima which had developed. This is the first report of a dissection between an atrial septum patch and pseudo-intima after mitral valve replacement (MVR) in a patient with infective endocarditis following an incomplete AVSD re...

BACKGROUND Iliac artery atherosclerotic disease may cause intermittent claudication and critical limb ischemia. It can lead to serious complications such as infection, amputation and even death. Revascularization relieves symptoms and prevents these complications. Historically, open surgical repair, in the form of endarterectomy or bypass, was used. Over the last decade, endovascular repair has...

BACKGROUND Surgical repair of left ventricular (LV) aneurysm has been performed for around 50 years. However, the most appropriate surgical approach remains undetermined. This study was undertaken to compare the efficacy of 2 established techniques, linear versus patch remodeling, for repair of dyskinetic LV aneurysms. METHODS We retrospectively reviewed the records of 49 patients (mean age, ...

Introduction: Thoracoscopic repair of congenital diaphragmatic hernia has increased with the use of prosthetic material. When the defect cannot be repaired primarily, a variety of materials have been used. The ideal prosthetic material has not been identified yet. The use of biologic tissue matrix prosthesis is appealing because this material may serve as a framework to support the patient’s ow...

Background Evidence is accumulating that, similar to other ventral hernias, umbilical and epigastric hernias must be mesh repaired. The difficulties involved in mesh placement and in meshrelated complications could be the reason many small abdominal hernias are still primary closed. In laparoscopic repair, a mesh is placed intraperitoneally, while the most common procedure is open surgery with ...

PURPOSE To determine the usefulness of slow-releasing paclitaxelin polytetrafluoroethylene/polylactide-co-glycolide (PTFE/PLGA) laminate for delayed adjustable strabismus surgery. METHODS A prospective, masked-observer, controlled study was performed in 25 rabbits. Fifty rabbit eyes were divided randomly into three groups. After recession of the superior rectus muscle (SRM), a PTFE/PLGA lamin...

A composite coating of polytetrafluoroethylene and epoxy shows 100 · improvements in wear resistance as compared to either of its constituents alone and reduced friction coefficient under testing on a pin-on-disk tribometer. This coating is made by impregnating an expanded PTFE film with epoxy, which provides three unique functions: (1) the epoxy compartmentalizes the PTFE nodes, which is belie...
