A 51-year-old female two years after CABG presented with unstable angina and inferior wall ischaemia. Coronary angiography revealed occluded graft to RCA and chronic total occlusion of RCA with good collateral flow from distal LAD to RCA. The CTO was successfully crossed and dilated through epicardial collaterals from distal LAD (retrograde approach). Finally, antegrade angioplasty with two ste...

This paper considers optimal routing and channel assignment (RCA) schemes to realize hypercube communication on optical mesh–like networks. Specifically, we identify lower bounds on the number of channels required to realize hypercube communication on top of array and ring topologies and develop optimal RCA schemes that achieve the lower bounds on these two topologies. We further extend the sch...

An 83-year-old man with known history of known coronary artery disease (prior coronary artery bypass surgery and percutaneous coronary intervention), hypertension, and hypercholesterolemia presented with ongoing exertional angina and dyspnea despite medical therapy. A dipyridamole rubidium-82 stress test showed moderate-sized ischemia in the inferior and inferolateral territory. An echocardiogr...

We report that QATPE, an aggregation-induced emission-active tetraphenylethene dye, can be used as a non-sequence-specific ssDNA probe for real-time monitoring of all rolling circle amplification (RCA) reactions, thus making RCA more suitable for biosensing applications.

Canonical Action Research (CAR) is a methodology for developing, testing and learning about information systems strategies through the use of real-world experiments. The methodology is based on five principles to ensure rigor and relevance. The first principle relates to the development of a researcher-client agreement (RCA) that facilitates collaboration between the researcher and the client. ...

During exercise, large pleural, abdominal, and transdiaphragmatic pressure swings might produce substantial rib cage (RC) distortions. We used a three-compartment chest wall model (J. Appl. Physiol. 72: 1338-1347, 1992) to measure distortions of lung- and diaphragm-apposed RC compartments (RCp and RCa) along with pleural and abdominal pressures in five normal men. RCp and RCa volumes were calcu...

A blockage of blood vessels resulting from thrombus or plaque deposit causes serious cardiovascular diseases. This study developed a computational model of blood flow and drug transport to investigate the effectiveness of drug delivery to the stenotic sites. A three-dimensional (3D) model of the curved stenotic right coronary artery (RCA) was reconstructed based on the clinical angiogram image....

A reversible cellular automaton RCA is a cellular automaton CA whose global func tion is injective and every con guration has at most one predecessor Margolus showed that there is a computation universal two dimensional state RCA But his RCA has non uniform neighbor so Morita and Ueno proposed state computation universal RCA using partitioned cellular automata PCA Because PCA can be regarded as...

In many photosynthetic organisms, tight-binding Rubisco inhibitors are released by the motor protein Rubisco activase (Rca). In higher plants, Rca plays a pivotal role in regulating CO2 fixation. Here, the ATPase activity of 0.005 mm tobacco Rca was monitored under steady-state conditions, and global curve fitting was utilized to extract kinetic constants. The kcat was best fit by 22.3 ± 4.9 mi...

To clarify the natural history and management of patients with aberrant origin of a coronary artery from the aorta, we reviewed 18 patients whose right (RCA) or left (LCA) coronary artery arose aberrantly and passed between the aorta and right ventricular infundibulum. Nine patients had aberrant LCA. Three young males died suddenly after exertion, each with proximal focal LCA stenosis. None of ...
