Background: The study of rheological properties of blood has special interest since it is a circulating fluid exposed to shear rates during its life time. This work aims to investigate the influence of whole body gamma irradiation on the rheological properties of rat’s blood. The applied shear rate was from 12 to 375 s-1. Low shear viscosity (up to 100 s-1) depends mainly on the erythroc...

Mefloquine, as a racemic mixture, is used for the treatment and prophylaxis of malaria. Stereoselective pharmacodynamic and pharmacokinetic differences has been observed for mefloquine. In this study a modified stereoselective HPLC method is presented for determination of mefloquine (MFQ) enantiomers in whole blood. The assay involved liquid-liquid extraction of MFQ from biological fluids with ...

A novel panfungal PCR assay which detects the small-subunit rRNA gene sequence of the two major fungal organism groups was used to test whole-blood specimens obtained from a series of blood or bone marrow transplant recipients. The 580-bp PCR product was identified after amplification by panfungal primers and hybridization to a 245-bp digoxigenin-labeled probe. The lower limit of detection of t...

The activity of oral clofazimine against intracellular Mycobacterium tuberculosis was compared to that of ofloxacin in healthy volunteers by the use of whole-blood cultures. Clofazimine was inactive whether it was tested alone or combined with other drugs that are used to treat multidrug-resistant tuberculosis, despite a total dose of 2 g. Kanamycin was the most active drug tested.

We have evaluated a new simple technique using whole blood from experimentally infected cattle for the isolation and cultivation of Theileria annulata. The study was carried out on 20 Holstein-Frisian bovines that had been experimentally infected with a virulent lethal dose of Theileria annulata. This technique has been compared to the classical peripheral blood monocyte isolation with Ficoll c...

background: mesenchymal stem cells (msc) have ability to regulate immune response via proinflamatory cytokines. in this study we aimed to investigate the effect of different mechanism for t cell activation and adjacency on immunoregulatory properties of msc. methods: bone marrow mscs were purchased and t cells were obtained from whole blood sample. t cells were activated by two different mechan...

BACKGROUND The gaseous headspace above naïve Escherichia Coli (E. coli) cultures and whole human blood inoculated with E. coli were collected and analyzed for the presence of trace gases that may have the potential to be used as novel, non-invasive markers of infectious disease. METHODS The naïve E. coli culture, LB broth, and human whole blood or E. coli inoculated whole blood were incubated...

An accurate elastic model of the human craniocervical arteries has been developed to study flow characteristics in normal and abnormal states (Kerber et al., paper presented at the annual meeting of the American Society of Neuroradiology, Orlando, March 1989). Flow perturbations at various Reynolds numbers can be created easily and the effects evaluated by observing the flow streamlines directl...
