A 56-year-old man was admitted to our hospital for elective coronary angioplasty of a chronic total occlusion (CTO) of the right coronary artery (RCA). After insertion of a right femoral sheath, the RCA was engaged with a 6 French Amplatz AL-2 (Cordis, Miami, Fl, USA) guiding catheter. Recanalization was begun using a 0.014-inch Miracle 3 guidewire (Asahi Intecc, Japan). At this stage, an ostia...
The cumulative percentage frequencies are presented for differences among reliable component analysis (RCA) scores for the verbal comprehension, perceptual organization, freedom from distractibility, and processing speed constructs assessed by the Wechsler Intelligence Scale for Children--Third edition (WISC-III) for the standardization sample and a learning disabled sample. Using RCA scores to...
Aroutine transthoracic echocardiogram (TTE) was performed in a 72-year-old woman with signs and symptoms of heart failure. The 2D TTE images revealed an enlarged right coronary artery (RCA) with reverse flow draining into the pulmonary trunk and the presence of dilated septal vessels (Figure 1). Coronary angiography and MRI confirmed the previous echocardiographic findings (Figures 2 to 4). Acc...
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 ...
The Aspergillus nidulans flbD gene encodes a protein with a Myb-like DNA-binding domain that is proposed to act in concert with other developmental regulators to control initiation of conidiophore development. We have identified a Neurospora crassa gene called rca-1 (regulator of conidiation in Aspergillus) based on its sequence similarity to flbD. We found that N. crassa rca-1 can complement t...
Using high-resolution PAGE and Western-blotting techniques the lectin Ricinus communis agglutinin-1 (RCA-1) was tested for its ability to recognize laminin subunits from the mouse Engelbreth-Holm-Swarm (EHS) tumour and from bovine cardiac and skeletal muscle. Biotinylated RCA-1 recognized both the A and B chains of purified EHS-tumour laminin with a sensitivity comparable to anti-(EHS laminin) ...
Detecting harmful bioactive compounds produced by bloom-forming pelagic algae is important to assess potential risks to public health. We investigated the application of a cell-based bioassay: the rainbow trout gill-w1 cytotoxicity assay (RCA) that detects changes in cell metabolism. The RCA was used to evaluate the cytotoxic effects of (1) six natural freshwater lake samples from cyanobacteria...
AIMS The last guidelines recommend a standardized 17-segment model for tomographic imaging of the left ventricle. The aim of this study is to analyse the correspondence of the 17 left ventricular segments with each coronary artery by myocardial perfusion SPECT studies. METHODS AND RESULTS Fifty patients selected for percutaneous revascularization of one coronary artery [24 left anterior desce...
The effect of the location of right coronary artery (RCA) lesions upon right ventricular ejection fraction (RVEF) during exercise was investigated using first-pass radionuclide angiography. Thirty-seven patients were studied at rest and during upright bicycle exercise: 11 controls (group 1) and 26 patients with significant (>70%) coronary artery stenosis, divided into those without lesions of t...
A novel rolling circle amplification (RCA) immunoassay based on DNA enriching magnetic nanoparticles and assembled fluorescent DNA nanotags, magnetic nanoparticles-RCA immunoassay, is developed as a versatile fluorescence assay platform for highly sensitive proteins detection.
