White cell (WBC)-reduction filters have been shown to be effective in removing infectious agents from infected blood products. In this study, the mechanisms of Trypanosoma cruzi (T. cruzi) retention by WBC-reduction filters were assessed. Human packed red blood cell (PRBC) and platelet concentrate (PC) samples were contaminated with T. cruzi organisms (Y strain; 3.4 x 10(6)/ml), and then filter...

Fourier transform infrared (FTIR)-spectroscopy has been found useful for monitoring the effectiveness of drugs during chemotherapy in leukemia patients. In the present work, spectral changes that occurred in the white blood cells (WBC) of an adult acute myeloid leukemia (AML) patient and their possible utilization for monitoring biochemistry of WBC were investigated. The phosphate absorbance fr...

OBJECTIVE The main aim of this study was to determine the relationship between the maternal white blood cell (WBC) count at the time of hospital admission in pregnancies complicated by preterm prelabor rupture of membranes (PPROM) and the presence of microbial invasion of the amniotic cavity (MIAC) and/or intra-amniotic inflammation (IAI). The second aim was to test WBC diagnostic indices with ...

Nucleated red blood cells (NRBC) in blood samples interfere with the white blood cell (WBC) count on many types of automated haematology analysers. This makes it necessary to correct the WBC count by counting NRBC microscopically. This report describes the evaluation of two analysers, the Cell-Dyn 4000 and the Sysmex XE-2100, which use new techniques to recognize and enumerate NRBC. We conclude...

In an attempt to develop biomarkers of chromate and nickel exposure, we have used a rapid, simple and sensitive 125I-postlabelling assay to detect the formation of DNA-protein crosslinks (DPCs) in different tissues from male Sprague-Dawley rats exposed i.p. to potassium chromate (K2CrO4) and nickel chloride (NiCl2). The results demonstrated that 20 h after rats were injected i.p. with these age...

UNLABELLED The effects of extreme cold on the human body are not fully understood, there are also no reports on the effect of cryogenic temperatures on the levels of erythropoietin (EPO) and interleukin 3 (IL-3), two important factors that regulate hematopoiesis. AIM determination of changes in peripheral blood cell counts and EPO and IL-3 levels induced by a series of 10, 20 and 30 standard ...

UNLABELLED The present study evaluated the role of SPECT/CT as an adjunct to (67)Ga (GS) or (111)In-labeled white blood cell (WBC) scintigraphy for diagnosis or localization of infection. METHODS Eighty-two patients (56 male and 26 female; mean age, 62 y) assessed for known or suspected infectious processes underwent 88 SPECT/CT studies. Forty-seven patients underwent GS SPECT/CT (13 with fev...

White blood cell (WBC) count is elevated in obesity (1) and is a risk factor for atherosclerosis (2). An elevated WBC count is present in impaired glucose tolerance (IGT) (3), and WBC count is associated with macroand microangiopathic complications in type 2 diabetes (4). In both of these studies, the effect was more marked in obese patients. In morbid obesity, bariatric surgery in many cases (...
