INTRODUCTION An anomalous origin and course of the right coronary artery (RCA)(1) is a very rare congenital anomaly that can be fatal if it remains undiscovered. PRESENTATION OF CASE In this case report, we present a patient with a one-year history of exercise-induced angina and dyspnea caused by anomalous origin of the RCA from the left sinus, and anomalous course between the aorta and the p...

We commercialized Reactive Coke Agglomerate (RCA), a cement-bonded pellet to decrease the thermal reserve zone temperature for the reduction of the reducing agent rate of blast furnaces. To achieve a high productivity of supplying RCA to large blast furnaces, a rapid curing process of RCA using steam was investigated. We obtained rapid curing of RCA within 18 h by combining primary curing for 1...

The aim of this study was to discuss the safety and efficacy of regional citrate anticoagulation (RCA) on continuous blood purification (CBP) during the treatment of multiple organ dysfunction syndrome (MODS). Thirty-five patients with MODS were divided into two groups: the local citrate anticoagulation (RCA) group, and the heparin-free blood purification (hfBP) group. The MODS severity was ass...

This article presents the design of a new asynchronous early output full adder which when cascaded leads to a relative-timed ripple carry adder (RCA). The relative-timed RCA requires imposing a very small relative-timing assumption to overcome the problem of gate orphans associated with internal carry propagation. The relative-timing assumption is however independent of the RCA size. The primar...

Background The proposed revision to the Accreditation Council for Graduate Medical Education (ACGME) Common Program Requirements includes participation in real or simulated patient safety activities, such as root cause analysis (RCA).1 Because exposure to RCA may occur with low frequency, a mock RCA was developed and piloted for feasibility with Hematology/Oncology fellows. Objective To impro...

the basal and mid septal segments, corresponding to significant stenoses in the LAD and RCA. (B) Coronary angiography reveals significant stenoses in the LAD and RCA. Figure 2: (A) Myocardial perfusion MRI with SW-CG-HYPR detects perfusion defects in the mid anterior, septal, and inferior segments, corresponding to significant stenoses in the LAD and RCA. (B) DE shows subendocardial hyperenhanc...

We report a case of the use of the GuideLiner catheter during transfemoral diagnostic angiography and intervention of an anomalous right coronary artery (RCA) after unsuccessful attempts to cannulate the RCA with other catheters. The GuideLiner catheter was successfully employed to coaxially engage the ostium of the RCA. Thrombotic disease appeared to be responsible for non-ST elevation myocard...

This study aims to evaluate the pavement performance of permeable asphalt concrete (PAC) produced with modified recycled coarse aggregate (RCA) based on six types single modification methods and three double methods. Firstly, water absorption, apparent density, crushing value RCA before after were tested. Subsequently, PAC these was investigated, including optimum asphalt-aggregate ratio, stabi...

We have utilized the cellular differentiation gradient and photomorphogenic responses of the first leaf of 7-day-old barley (Hordeum vulgare L.) to examine the accumulation of mRNA and protein encoded by the ribulose-1,5-biphosphate carboxylase holoenzyme (rubisco) activase gene (rca). Previous studies have revealed a pattern of coordinate expression of rubisco subunit polypeptides during devel...
