Point-of-care testing (POCT) is defined as testing performed outside of the central laboratory at or near the patient’s bedside. A number of devices have been developed that permit a wide menu of tests to be performed at the POC. In most cases the unit cost of POC tests is greater than similar testing performed in the central laboratory. For this reason when implementing POCT it is important to...

Empirical relationships between particulate organic carbon (POC) and inherent optical properties (IOPs) are required for estimating POC from ocean-color remote sensing and autonomous platforms. The main relationships studied are those between POC and particulate attenuation (cp) and backscattering (bbp) coefficients. The parameters of these relationships can however differ considerably due to d...

BACKGROUND Point-of-care (POC) diagnostic tests with good sensitivity and specificity are needed for diagnosing failure of transfer of passive immunity (FTPI) in foals. Turbidimetric immunoassays (TIA) have these characteristics and provide quantitative results. A commercially available TIA-based POC test (POC-TIA) has not been validated in horses. OBJECTIVE To validate a POC-TIA and compare ...

This paper proposes a client architecture for the Push to Talk over Cellular (PoC) service based on the Open Mobile Alliance (OMA) PoC specifications v1.0 release. We show that most standard VoIP modules can be reused for the PoC client, and the VoIP software can be easily extended to support PoC service. Then we present the detailed message flows between the PoC client and other network entiti...

Point of care (POC) testing in the Emergency Department (ED) is becoming more common. The implementation and maintenance of POC testing in the ED, however, is a complex issue. We performed a systematic review of the English language literature published between 1985 and June 2001 with a focus on POC testing and ED application. Articles that addressed the following were included in the review: i...

Size-fractionated particulate 234Th and particulate organic carbon (POC) fluxes were measured in the Gulf of Mexico during 2000 and 2001 in order to obtain a better estimation of upper ocean organic carbon export out of the euphotic zone within cold core and warm core rings, and to assess the relative merit of sediment trap and POC/234Th methods. In 2000, the flux of POC measured by sediment tr...

Push-to-talk over Cellular (PoC) provides walkie– talkie like service in the cellular telecommunications network [9]. In this service, several predefined PoC group members participate in one PoC session. Since the PoC session is half-duplex, only one group member speaks at a time, and the others listen. Therefore, a user must ask for the permission to speak by pressing the push-to-talk button. ...

Carbon cycling in inland waters has been identified as an important, but poorly constrained component of the global carbon cycle. In this study, we compile and analyze particulate organic carbon (POC) concentration data from 1145 U.S. Geological Survey (USGS) gauge stations to investigate the spatial variability and environmental controls of POC concentration. We observe substantial spatial var...

Postconditioning (POC), a novel strategy of cardioprotection against ischemia-reperfusion injury, is clinically attractive because of its therapeutic application at the predictable onset of reperfusion. POC activates several intracellular kinase signaling pathways, including phosphatidylinositol 3-kinase (PI3K)-Akt (RISK). The regulation of POC-induced survival kinase signaling, however, has no...
