Regional citrate anticoagulation (RCA) is now recommended over systemic heparin for continuous renal replacement therapy in patients without contraindications. Its use is likely to increase throughout the world. However, in the absence of citrate blood level monitoring, the diagnosis of citrate accumulation, the most feared complication of RCA, remains relatively complex. It is therefore common...

Relational Concept Analysis (RCA) facilitates the discovery of new abstractions in data descriptions including relations. A model driven approach for RCA implementation makes possible to deal with most input data (models) simply by configuring the transformation for the chosen input data type (metamodel). Until now, we only applied this approach to one-level models (mainly class models). In thi...

Figure 4. RCA images of two subjects acquired from the optimal time windows determined from Fig. 3. Note that the RCA is well depicted for each subject, with distal portion and small branches visible as indicated by the red arrows. Figure 2. Motion curve of a volunteer indicates that minimal 3D cardiac motion is expected around 78% of the R-R interval. RCA image acquired in this time period (b)...

This data presented herein are the research summary of "mechanical behavior and durability performance of concrete containing recycled concrete aggregate" (Paul, 2011) [1]. The results reported in this article relate to an important parameter of optimum content of recycle concrete aggregate (RCA) in production of new concrete for both structural and non-structural applications. For the purpose ...

Purpose: To evaluate image quality and cardiovascular enhancement after triphasic injection in 64-slice-CT coronary angiography (c-CTA). Methods: c-CTA of twenty-two asymptomatic patients following triphasic injection (65ml-contrast bolus + mixed 30mlcontrast and 20ml-saline bolus + 50ml-saline chaser) were retrospectively reviewed. Attenuation in the great vessels, cardiac chambers, and corona...

Coronary arterial tree extraction in angiograms is an essential component of each cardiac image processing system. Once physicians decide to check up coronary arteries from x-ray angiograms, extraction must be done precisely, fast, automatically and including whole arterial tree to help diagnosis or treatment during the cardiac surgical operation. This application is very helpful for the surgeo...

BACKGROUND Percutaneous coronary intervention (PCI) for anomalous right coronary artery (RCA) arising from the left sinus of Valsalva (LSOV) is a technical challenge due to inadequate guiding catheter support to overcome the acute rightward course of the anomalous RCA. In this study we describe a novel technique for PCI for an anomalous RCA arising from the LSOV. METHODS Six patient cases wit...

Many learning algorithms use a metric defined over the input space as a principal tool, and their performance critically depends on the quality of this metric. We address the problem of learning metrics using side-information in the form of equivalence constraints. Unlike labels, we demonstrate that this type of side-information can sometimes be automatically obtained without the need of human ...

In 2006, the Quality and Safety Committee of the Society for Pediatric Anesthesia initiated a quality improvement project for the specialty of pediatric anesthesiology that ultimately resulted in the development of Wake Up Safe (WUS), a patient safety organization that maintains a registry of de-identified, serious adverse events. The ultimate goal of WUS is to implement change in processes of ...

Asbestos fibres can be transformed into potentially non-hazardous silicates by high-temperature treatment via complete solid-state transformation. A549 cells were exposed to standard concentrations of raw cement asbestos (RCA), chrysotile and cement asbestos subjected to an industrial process at 1200 degrees C (Cry_1200 and KRY.AS, respectively), raw commercial grey cement (GC). Cell growth rat...
