1. Evaluation of the effects of ischemic preconditioning on the hematological parameters of rats subjected to intestinal ischemia and reperfusion
OBJECTIVES: Intestinal ischemia/reperfusion often leads to acute lung injury and multiple organ failure. Ischemic preconditioning is protective in nature and reduces tissue injuries in animal and human models. Although hematimetric parameters are widely used as diagnostic tools, there is no report of the influence of intestinal ischemia/reperfusion and isch

2. Early HHV-6 replication is associated with morbidity non-related to CMV infection after kidney transplantation
Human herpesvirus type 6-(HHV-6) has been associated with morbidity after liver transplantation. OBJECTIVE: The aim of this study was to determine the HHV-6 seroprevalence among donor-recipient pairs, analyze the incidence of early active infection, its clinical manifestation, interaction with CMV, and the related morbidity in the first year after kidney tra

3. Expressão do fator estimulador de colônia de granulócito humano recombinante (rhG-CSF) em Escherichia coli. / Expression of recombinant human colony stimulating factor (rhG-CSF) in Escherichia coli.
The recombinant human granulocyte colony stimulating factor (rhG-CSF) is a non-glycosylated protein with 175 amino acids. This factor plays an important role in hematopoietic cell proliferation and has been widely used for treating neutropenia. The purpose of this work is to construct two expression systems in E. coli; a system for obtaining rhG-CSF in the c

4. Expressão genica global e estudo do gene JUNB em policitemia vera / Global gene expression and study of the JUNB gene in polycythemia
Polycythemia vera (PV) is a chronic myeloproliferative disorder that arises through clonal proliferation of multipotent hematopoietic progenitors. PV patients present bone marrow trilineage expansion, leading to increased production of mature red cells, granulocytes and platelets. Important PV features are elevated red cell mass, despite normal or subnormal

5. Cell populations in lesions of cutaneous leishmaniasis of leishmania (L.) amazonensis- infected rhesus macaques, Macaca mulatta
The cellular nature of the infiltrate in cutaneous lesion of rhesus monkeys experimentally infected with Leishmania (L.) amazonensis was characterized by immunohistochemistry. Skin biopsies from infected animals with active or healing lesions were compared to non-infected controls (three of each type) to quantitate inflammatory cell types. Inflammatory cells

6. Yops of Yersinia enterocolitica Inhibit Receptor-Dependent Superoxide Anion Production by Human Granulocytes
The virulence plasmid-borne genes encoding Yersinia adhesin A (YadA) and several Yersinia secreted proteins (Yops) are involved in the inhibition of phagocytosis and killing of Yersinia enterocolitica by human granulocytes. One of these Yops, YopH, dephosphorylates multiple tyrosine-phosphorylated proteins in eukaryotic cells and is involved in the inhibitio

7. Interactions between human granulocytes and Blastomyces dermatitidis.
We studied interactions in vitro between human granulocytes and the yeast-like form of Blastomyces dermatitidis, because granulocytes are prominent in the host response to systemic blastomycosis. In Boyden chamber assays, broth culture filtrates of B. dermatitidis contained levels of granulocyte chemotactic activity that were significantly higher than those

8. Role of Yops in inhibition of phagocytosis and killing of opsonized Yersinia enterocolitica by human granulocytes.
The virulence plasmid of Yersinia enterocolitica codes for the production of the outer membrane protein YadA and the secretion of several proteins, called Yops, which may play a role in the interaction between granulocytes and this bacterium. We investigated whether the expression of YadA or the secretion of Yops affected the phagocytosis and killing of opso

9. Interleukin-8 enhances nonoxidative intracellular killing of Mycobacterium fortuitum by human granulocytes.
The results of this study show that recombinant interleukin-8 (IL-8) enhances the intracellular killing of Mycobacterium fortuitum by human granulocytes. This chemokine did not stimulate the phagocytosis of M. fortuitum by granulocytes at various bacterium-to-cell ratios. The killing process was not affected by the NADPH oxidase inhibitor diphenyleneiodonium

10. Detection, Pathogenesis, and Prevention of Damage to Human Granulocytes Caused by Interaction with Nylon Wool Fiber: IMPLICATIONS FOR FILTRATION LEUKAPHERESIS
Granulocytes collected by reversible adhesion to nylon wool fiber (NWF) function relatively well in standard in vitro tests; however, they have an abnormally shortened survival time in the circulation. Assuming that this rapid disappearance represents clearance and that recognition by phagocytes is important for such clearance, we used an autologous in vitro

11. Lipid Peroxidation by Human Blood Phagocytes
Cell suspensions enriched in human blood monocytes, obtained from normal peripheral blood by sedimentation on sodium diatrizoate-Ficoll gradients or from the blood of patients with neutropenia and monocytosis, accumulated malonyldialdehyde, a labile catabolite of lipid peroxidation, during incubations with polystyrene beads or heat-killed Staphylococcus epid

12. Generation of leukotrienes from human granulocytes by alveolysin from Bacillus alvei.
We investigated the effect of alveolysin on human granulocytes. Alveolysin is an exoprotein produced by Bacillus alvei and belongs to the group of sulfhydryl-activated cytolysins. Other members of this group are streptolysin O and theta-toxin from Clostridium perfringens. It is demonstrated that alveolysin leads to leukotriene generation from human granulocy
