Root cause analysis (RCA) is a recommended practice in retrospectives and cause-effect diagram (CED) is a commonly recommended technique for RCA. Our objective is to evaluate whether CED improves the outcome of RCA and the perceptions of retrospective participants. We conducted a controlled experiment with eleven student software project teams by using two-by-two crossover design resulting in t...

INTRODUCTION The objective of this case report was to illustrate the diagnostic and intervention approach of anomalous right coronary artery (RCA). CLINICAL PICTURE A 60-year-old man presented with acute inferior myocardial infarction. Cardiac catheterisation revealed an anomalous RCA arising from the posterior coronary sinus as the infarct-related artery. TREATMENT Ad hoc percutaneous coro...

The anomalous origin of the right coronary artery (RCA) from the left anterior descending (LAD) artery is rare. We report a case of single coronary artery with proximal LAD severe stenosis. The RCA originated from an unreported course of conal branch from the LAD. This anomalous RCA also had collaterals from left circumflex. Coronary intervention was successfully carried out on a severe stenosi...

One of the single anomalous origins of coronary artery that has rarely been reported is a congenital anomaly of coronary circulation that occurs in the left coronary artery originating from the right coronary sinus of valsalva. We report a 49-year-old male patient with non-ST segment elevated myocardial infarction that was identified to have an anomalous origin of the left coronary artery from ...

The congenital absence of the left circumflex artery and a compensatory super-dominant right coronary artery (RCA) is a very rare benign coronary anomaly in the clinic. The presence of a massive thrombus in the super-dominant RCA can lead to fatal results in cases of acute myocardial infarction, unless the thrombus is mechanically removed. Aspiration of the thrombus using a 6 Fr right Judkins g...

Abstract: We present an experience of applying an extension of Formal Concept Analysis to UML class model restructuring. The Relational Concept Analysis (RCA) mines potentially useful abstractions from UML classes, attributes, operations and associations and therefore outscores competing restructuring techniques which usually focus exclusively on classes. Nevertheless, the complexity and the si...

BACKGROUND Recent guidelines suggest the adoption of regional citrate anticoagulation (RCA) as first choice CRRT anticoagulation modality in patients without contraindications for citrate. Regardless of the anticoagulation protocol, hypophosphatemia represents a potential drawback of CRRT which could be prevented by the adoption of phosphate-containing CRRT solutions. The aim was to evaluate th...

The IAEA/RCA (Regional Cooperative Agreement) project to strengthen and harmonize radiation protection infrastructures in Asian and Pacific region started in 1988. The number of the RCA member countries is 17 at present. In the early stages of the project, there was little information on the status of radiation protection and their technical abilities of radiation protection measurements in RCA...

In molecular resolution refutation, the detection of empty clauses is important. We propose a rolling circle amplification-based detection method for resolution refutation. The rolling circle amplification (RCA) technique is known to be able to distinguish and amplify circular DNA. In this paper, we describe the representation of clauses and the RCA-based detection method. Bio-lab experiments s...

BACKGROUND Bilateral internal thoracic artery (BITA) grafting with a composite T-graft enables right coronary artery (RCA) system revascularization with the distal end of the free right internal thoracic artery (RITA). This study compares this grafting technique to left-sided BITA grafting and RCA revascularization with the right gastroepiploic artery (RGEA) and saphenous vein grafts (SVG). M...
