The back-flow of an aortic valvo-pump will reduce the pumping flow rate but can wash out the gap between the rotor and the stator, and thus can improve the antithrombogenicity of the device. To investigate the regurgitation of a 23mm OD aortic valvo-pump, its closed impeller was replaced by a cylinder and hereby the valvopump had lost its pumping function. The pressure head crossing the aortic ...

A pooled sample of hair was divided and portions prepared for analysis by three washing procedures, to evaluate the effect of washing procedure on the subsequent trace-element (Zn, Cu, Mg) content. The methods selected were a detergent wash, a hexane-ethanol wash, and an acetone-ether-detergent wash. For all elements, there was a significant difference among the results after these wash procedu...

BACKGROUND Home hemodialysis is common in New Zealand and associated with lower cost, improved survival and better patient experience. We present the case of a fully trained home hemodialysis patient who exsanguinated at home as a result of an incorrect wash back procedure. CASE PRESENTATION The case involves a 67 year old male with a history of well controlled hypertension and impaired gluco...

The "watercolor effect" is the wash of illusory color that fills in between two enclosing bichromatic contours. We studied the microgenesis of this illusion by varying the duration of the eliciting stimulus (a yellow/purple contour outlining the Mediterranean Sea) and by varying the duration of a blank interval from stimulus offset to an after-coming mask (the ISI). The illusory wash was rated ...

Childhood wasting is a global problem and is significantly more pronounced in low and middle income countries like Bangladesh. Socio Economic Status (SES) and Water, Sanitation and Hygiene (WASH) practices may be significantly associated with wasting. Most previous research is consistent about the role of SES, but the significance of WASH in the context of wasting remains ambiguous. The effect ...

BACKGROUND The therapeutic effect of chemotherapy for liver metastases is currently determined by changes in tumor diameter depicted on computed tomography (CT) and magnetic resonance imaging, but it cannot accurately determine if there is central necrosis. Furthermore, due to the risk of radiation exposure and high cost, frequent examination using these methods places a heavy burden on patient...
