Severe anemia is an important cause of morbidity and mortality among children in resource-poor settings, but laboratory diagnostics are often limited in these locations. To address this need, we developed a simple, inexpensive, and color-based point-of-care (POC) assay to detect severe anemia. The purpose of this study was to evaluate the accuracy of this novel POC assay to detect moderate and ...

It is well known that high rates of fusion failure and pseudoarthrosis development (5~35%) are concomitant in spinal fusion surgery, which was ascribed to the shortage of suitable materials for bone regeneration. Citrate was recently recognized to play an indispensable role in enhancing osteconductivity and osteoinductivity, and promoting bone formation. To address the material challenges in sp...

The agricultural industry in Malaysia has grown rapidly over the years. Palm oil clinker (POC) is a byproduct obtained from the palm oil industry. Its lightweight properties allows for its utilization as an aggregate, while in powder form as a filler material in concrete. POC specimens obtained throughout each state in Malaysia were investigated to evaluate the physical, chemical, and microstru...

Surface concentrations and vertical fluxes of particulate organic carbon (POC) were assessed in the Amundsen Gulf (southeastern Beaufort Sea, Arctic Ocean) over the years 2004 to 2006 by using ocean color remote-sensing imagery and sequential sediment traps moored over the ca. 400m isobath. Environmental conditions (sea ice, wind) and oceanographic variables (temperature, salinity, fluorescence...

Saliva reflects the physiologic state of the body, including emotional, endocrinal, nutritional and metabolic variations, and so can be used to monitor both oral and systemic health. In the past decade, salivary diagnostic approaches have been developed to monitor oral and systemic diseases. Along with these exciting scientific advancements, there is an emerging need to move salivary diagnostic...

On the shores of Lake Chad, schistosomiasis among mobile pastoralists was investigated in a field laboratory. Point-of-care circulating cathodic antigen (POC-CCA) cassette test, reagent strip, and filtration were conducted on urine samples. Fresh stool samples were subjected to the Kato-Katz technique, and fixed samples were examined with an ether-concentration method at a reference laboratory....

We use satellite data from Sea-viewing Wide Field-of-view Sensor (SeaWiFS) to investigate distributions of particulate organic carbon (POC) concentration in surface waters of the north polar Atlantic Ocean during the spring–summer season (April through August) over a 6-year period from 1998 through 2003. By use of field data collected at sea, we developed regional relationships for the purpose ...

OBJECTIVES To determine if point-of-care (POC) glycated haemoglobin (HbA₁c) is sufficiently accurate in real-world remote settings to predict or exclude the diagnosis of diabetes based on laboratory HbA1c measurements. DESIGN Cross-sectional study comparing POC capillary HbA₁c results with corresponding venous HbA₁c levels measured in a reference laboratory. PARTICIPANTS Aboriginal patients...

BACKGROUND Reactive oxygen species (ROS) play a major role in causing injury in ischemia-reperfusion (I/R). Mitochondrial DNA (mtDNA) is particularly vulnerable to oxidative damage. We propose that increased mitochondrial ROS production is likely to damage mtDNA, causing further injury to mitochondria, and postconditioning (POC) may ameliorate kidney I/R injury by mitigating mitochondrial damag...

BACKGROUND AND PURPOSE Thrombolysis in patients using oral anticoagulants (OAC) and in patients for whom information on OAC status is not available is frequently delayed because the standard coagulation analysis procedure in central laboratories (CL) is time-consuming. By using point-of-care (POC) coagumeters, international normalized ratio (INR) values can be measured immediately at the bedsid...
