Ciguatera diagnosis relies on clinical observations associated with a recent consumption of fish. Although needed, direct confirmation of exposure in subjects showing ciguatera disease symptoms is currently unavailable. We previously reported that ciguatoxins were measurable in the blood of mice exposed to extracts of Pacific ciguatoxins isolated from Gambierdiscus polynesiensis, ...

In this paper, a newly developed eigendecomposition-based adaptive filter is applied in flow velocity estimation and its performance is evaluated and compared with the static polynomial regression filter. Results demonstrate that the eigendecomposition-based filter is the fully-adaptive and can not only suppress the clutter signals with minimal loss of low-flow ...

BACKGROUND: Leishmania is an intracellular parasite of monocytes transmissible by transfusion. The feasibility of reducing Leishmania with leukodepletion filters was studied. At collection, infected blood contains the amastigote form of Leishmania within monocytes. Amastigotes cause the rupture of monocytes releasing free amastigotes that convert to promastigotes, which exist extracellularly at ...

Deficiency of glucose-6-phosphate dehydrogenase (G6PD) causes acute hemolytic anemia triggered by oxidative drugs such as primaquine. It is therefore essential in malaria-endemic areas for malaria patients to be confirmed for their G6PD activity before taking primaquine. The WST-8 method, a newly established screening method for G6PD deficiency, has been demonstrated ...

Miniaturized biochemical devices in glass, silicon and polymer materials are starting to find their way from the academic laboratories to real-life applications. However, most attention has been given to miniaturize the downstream functions of various microfluidic systems, leaving the sample introduction and preparation steps to more conventional, bulkier solutions. For ...

Calcitonin gene-related peptide (CGRP) has roles as a neurotransmitter, neuromodulator and trophic factor. CGRP has been reported to be elevated in neonatal blood of children with autism or mental retardation as compared with normal subjects by recycling immuno-affinity chromatography (RIC). While CGRP detection in neonatal blood is thus important, it ...

Flow distributions are critical determinants in the function of hemofilters. Despite their importance, however, flow distributions cannot currently be measured in filters during experimental or clinical applications. Here, we demonstrate that the thermal conduction properties of extracorporeal circuits may provide a tool to overcome this limitation. More specifically, we show ...

Vertical flow constructed wetlands (VFCWs) have been very successful in France over the last 5 years. The sizing of VFCWs is still roughly based on organic load acceptance with slight clear water intrusion into the sewerage system which is often wrong in the context of small communities. To specify the ...

In filtration, the concept of pore size is not easy to define. In microfiltration, there are numerous advantages in employing a surface filtering membrane, rather than one relying on depth filtration mechanisms from a tortuous pore flow channel. Modern manufacturing techniques provide means to produce surface filtering membranes. For filtration, ...

Phlebotomists at the Jackson-Madison County General Hospital perform more than 18,000 venipunctures a month to collect blood specimens for laboratory tests. Because each of the blood draws involves handling five or six labels for the tubes that the blood is collected in, it means the hospital prints about 90,000 labels ...
