introduction: leukocytes causing a wide variety of side effects after transfusion are present in all blood products prepared by standard methods. as a consequence, the use of filter technology for leukoreduction has been widely practiced .according to aabb accreditation in 1996, leukoreduced blood components must contain less than 5×106 leukocytes per unit, but sometimes this value is higher ev...

The conversion of lignocellulosic biomass into fine chemicals and polymers has been gaining attention recently. Regenerated lignocellulose beads (RLBs) were prepared by an emulsification/precipitation technique, using wheat straw as a raw material and [Bmim]Cl as a solvent. The morphology and properties of the obtained beads were characterized. The RLBs were perfectly spherical, with a porous m...

PURPOSE To determine how a biomicroscope illumination system affects the grading of anterior chamber (AC) inflammation. DESIGN Laboratory investigation. METHODS An artificial AC was designed to replicate optically a human AC and was filled with 5-mum polystyrene beads suspended in ethanol. A high-definition video eyepiece camera recorded the moving beads. Using image processing software, th...

Three types of gentamicin beads were compared in a rat osteomyelitis model. The gentamicin beads were prepared in cylinder shape (diameter 2 mm x height 4 mm). Gentamicin impregnated polymethylmethacrylate (GIPMMA) beads were fabricated according to manufacturer’s instructions. Gentamicin coated native calcium sulfate (GNCS) bead and gentamicin coated high porous calcium sulfate (G-HPCS) bead w...

To decrease child mortality due to common but life-threatening illnesses, community health workers (CHWs) are trained to assess, classify and treat sick children. For pneumonia, CHWs are trained to count the respiratory rate of a child with cough and/or difficulty breathing, and determine whether the child has fast breathing or not based on how the child's breath count relates to age-specific r...

Purpose: Psylliumseeds are used in traditional herbal medicine to treat various disorders. Moreover, as a soluble fiber, psyllium has potential to stimulate bacterial growth in digestive system. We aimed to substitute alkali-extractable polysaccharides of psyllium for alginate in beads with second coat of poly-l-lysine to coat Lactobacillus acidophilus. Methods: Beads were prepared using extrus...
