Chediak-Higashi (CH) syndrome, a genetic disease affecting man and other animals, is partially characterized by defective platelets that lack serotonin and dense bodies and by impaired leukocyte function where chemotaxis, degranulation, and bacterial killing are decreased. The effects of normal platelets containing serotonin and of reagent serotonin on the subnormal microbicidal activity of CH ...

Leukocyte differential count is one of the most frequently ordered clinical tests in hospitals. This paper reports a point-of-care test for the leukocyte count by using a microflow cytometer and a fluorescent dye assay. The dye assay relied on fluorescent detection alone to count leukocytes in blood and to identify leukocyte subtypes. By combining the fluorescent assay with a sheathless microfl...

OBJECTIVE We sought to determine factors associated with the absence of pyuria in symptomatic children whose urine culture was positive for a known uropathogen. METHODS We obtained data on children evaluated at the Children's Hospital of Pittsburgh emergency department between 2007 and 2013 with symptoms of urinary tract infection (UTI) who had paired urinalysis and urine cultures. We exclude...

BACKGROUND The 2011 American Academy of Pediatrics urinary tract infection (UTI) guideline suggests incorporation of a positive urinalysis (UA) into the definition of UTI. However, concerns linger over UA sensitivity in young infants. Infants with the same pathogenic organism in the blood and urine (bacteremic UTI) have true infections and represent a desirable population for examination of UA ...

During the fermentation of sugars to ethanol relatively high levels of an undesirable coproduct, ethyl acetate, are also produced. With ethanologenic Escherichia coli strain KO11 as the biocatalyst, the level of ethyl acetate in beer containing 4.8% ethanol was 192 mg liter(-1). Although the E. coli genome encodes several proteins with esterase activity, neither wild-type strains nor KO11 conta...

Streamline and Improve Your Genotyping and Genetic Studies Applied Biosystems has designed BloodPrepTM Chemistry for quick and efficient DNA purification from many sample matrices, including: fresh and frozen whole blood from various animal species in all common anticoagulants, isolated blood cells such as “buffy coat” or leukocyte fractions, cultured cells, and buccal swabs. Novel reagent form...

The effects of colony-stimulating factors on differentiation of leukemic progenitor cells were investigated in various types of acute nonlymphocytic leukemia. Two different sources of colony-stimulating factors were used in this study: human placental conditioned medium; and phytohemagglutin-stimulated leukocyte-conditioned medium. At the end of culture, colony types were determined by dual est...

Urinalysis as a simple, non invasive and inexpensive laboratory test remains to be the cornerstone tool in the assessment of the urinary system. It can be easily used for screening of kidney diseases. Previously many screening programs using urinalysis have been carried out using reagent strips testing, and their effectiveness in evaluating kidney disorders with relatively low costs [1,2]. Mass...

An intervention study was conducted in Khamir, north of Sana'a, for control of urinary schistosomiasis using chemotherapy and health education. The validity and cost-effectiveness of reagent strips as a rapid diagnostic tool to screen for Schistosoma haematobium infection was also assessed along with visible haematuria. Prevalence of S. haematobium infection 14 months post-intervention fell fro...
