Evaluation of leukocyte removal filters modelled by use of HIV-infected cells and DNA amplification.
The concept of reducing cell-associated blood-borne viruses (BBVs) by filtration of the vector leukocytes from blood collected for transfusion has led to the development of high efficiency filters. Improved filtration technology demands newer methodology to accurately estimate the residual cells. We have developed an experimental model based on the hemocytometer counts and the polymerase chain ...
متن کاملLack of clinically significant contact system activation during platelet concentrate filtration by leukocyte removal filters.
When blood (plasma) contacts certain foreign surfaces, factor XII can activate and trigger a series of reactions leading to cleavage of kininogens with subsequent release of bradykinin. In this study, we investigated two different widely used leukocyte removal filters, Pall PXL8K (A) and Asahi PLS-5A (B), to test whether clinically significant contact activation occurred during leukodepletion o...
متن کاملClinical efficacy and biocompatibility of three different leukocyte and fat removal filters during cardiac surgery.
Activated leukocytes and fat particles are associated with organ injury after a cardiac surgery. Filters are currently used to remove either leukocytes or fat particles. A novel approach with a filter that combines leukocyte and fat removal might be clinically useful. As it is not known which type of filter has a good and safe performance in both leukocyte and fat removal, we measured in this s...
متن کاملEvaluation of two types of leukocyte removal filters on transfusion dependent thalassaemics.
The advent of leukocyte filters has enabled effective removal of leukocytes from certain blood products thus avoiding many adverse effects of blood transfusion. Many different materials have been incorporated into these filters to achieve >95% leukocyte removal. In this study we evaluated the efficacy of leukocyte removal of two different filters, using actual bedside transfusion settings invol...
متن کاملUse of total variation filters in SPECT medical imaging
Total variation denoising filtering is proposed as an alternative to the Butterworth filter, which is widely used in the reconstruction of SPECT medical images. Its advantages lie in the preservation of the image edges while the noise is removed, as opposed to the blurring that characterizes Butterworth filtered images. However, results show that total variation filtering application to SPECT m...
