Titanium dioxide nanoparticles (TiO2 NPs) have been extensively used in industry, medicine, and daily life, and have shown potential toxic effects for animals or humans. We noted that the effects of TiO2 NPs on the immune system and its mechanism of action in animals or humans have not been elucidated. Thus, mice were exposed to the TiO2 NPs (0, 1.25, 2.5, or 5 mg kg(-1) body weight) for 9 consecutive months. Exposure to TiO2 NPs was accumulated in the thymus, leading to a decrease in body weight and increases in the weight of the thymus or thymus indices...

Platelet activation and platelet-derived cytokines contribute to the vascular inflammation and increased thrombotic activity known to occur in patients with sickle cell anemia (SCA). CD40 ligand (CD40L), a platelet-associated pro-inflammatory molecule that promotes endothelial cell activation, is elevated in the circulation of SCA patients. We sought to evaluate the association of CD40L and inflammation with sickle-related clinical complications and laboratory variables in SCA patients. Soluble CD40L, thrombospondin (TSP)-1 and tumor necrosis factor (TNF)-α were determined in the platelet-poor plasma of healthy individuals and steady-state SCA patients by ELISA...

Equine piroplasmosis in donkeys has been recognised as a serious problem of major economic importance. The present molecular study is the first investigation of the presence of Theileria equi and Babesia caballi in Balkan donkeys and of the possible haematological alterations related to it. A total of 70 apparently healthy donkeys from Serbia were included in this study. The overall prevalence of T. equi infection in donkeys tested with multiplex PCR was 50%. There was no B. caballi-positive sample. Infections in donkeys included in this study seem to be associated with decreased red blood cell count, haemoglobin concentration, haematocrit and platelet count, and with increased white blood cell count, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration...

We have utilized Raman tweezers to measure and assign micro-Raman spectra of optically trapped, live red blood cells (RBCs), white blood cells (WBCs) and platelets. Various types of WBCs- both granulocytes, lymphocytes, and their different types have been studied. The Raman bands are assigned to different biomolecules of blood cells. The Raman spectra thus obtained has been enabled detection of β-carotene in these blood cells, the spectral features of which act as a signature that facilitates experimental probing of the effect of 785nm laser light on different blood cells as a function of incident laser power in the mW range...

INTRODUCTION: Routine hematology parameters in hematopoietic progenitor cell apheresis products (HPC-A) are usually determined using automated cell counters. These instruments, however, are designed to analyze whole blood samples, that differ considerably from HPC-A in blood cell composition. This study evaluates the performance of two automated cell counters for the analysis of HPC-A. METHODS: Routine hematology parameters [red blood cells (RBC), hematocrit (HCT), mean corpuscular volume (MCV), white blood cells (WBC), WBC differentiation, and platelets (PLT)] were determined on the Unicel DxH 800 instrument (Beckman Coulter) and the XN-350 instrument (Sysmex)...
