BACKGROUND: Hantavirus disease is characterized by endothelial dysfunction. Angiopoietin-1 (Ang-1) and its antagonist angiopoietin-2 (Ang-2) play a key role in the control of capillary permeability. Ang-1 is responsible for maintenance of cell-to-cell contacts whereas Ang-2 destabilizes monolayers. An imbalance of Ang-1 and Ang-2 levels results in enhanced permeability and capillary leakage. OBJECTIVES: To analyze the involvement of angiopoietins in hantavirus-induced disruption of endothelia, we measured the levels of Ang-1 and Ang-2 in hantavirus infection...

BACKGROUND: Patients in the intensive care unit frequently require antibiotic treatment. Liver impairment possesses substantial challenges for dose selection in these patients. The aim of the present pilot study was to assess the novel maximal liver function capacity (LiMAx test) in comparison to conventional liver function markers as covariates of drug clearance in liver failure using linezolid as model drug. METHODS: 28 patients with different degrees of liver failure were recruited and LiMAx test, plasma, dialysis and urine sampling was performed under linezolid steady-state therapy (600 mg BID)...

Cell suspensions of head kidney and spleen of black scorpionfish (Scorpaena porcus L.) have been studied using flow cytometry and light microscopy. On the basis of forward scatter (FS) and side scatter (SS) distribution and light microscopy two main types of cells in the hemopoietic organs were identified: "small cells" (5,1-8,9 µm) and "large cells" (10,8-15,3 µm). Subpopulation of small cells was formed by thrombocytes, lymphocytes and elements with functionally inactive nuclei. Euchromatin level in their nuclei was low and acidophilic cytoplasm corresponded to negligible nucleic acids content...

Immune toxicity of polycyclic aromatic hydrocarbons (PAHs) in fishes has been frequently reported but the reasons for differential cell toxicity remains unclear. Rainbow trout were exposed in vivo with a single intraperitoneal injection of corn oil or 100mg/kg of the immunotoxic PAH benzo[a]pyrene (B[a]P) in corn oil. Leukocytes were harvested from head kidney, spleen and blood after 14days, the optimal time for B cell depletion found in a previous study. The mRNA expression of five cytochrome P450 (CYP) enzymes, the aryl hydrocarbon receptor (AhR), and an intrinsic pathway apoptosis checkpoint (p53) in B cells and thrombocytes were examined...

The receptors for the pituitary hormones growth hormone (GH), prolactin (PRL) and somatolactin (SL), and the hematopoietic hormones erythropoietin (EPO) and thrombopoietin (TPO), comprise a structurally related family in the superfamily of cytokine class-I receptors. GH, PRL and SL receptors have a wide variety of effects in development, osmoregulation, metabolism and stimulation of growth, while EPO and TPO receptors guide the production and differentiation of erythrocytes and thrombocytes, respectively. The evolution of the receptors for GH, PRL and SL has been partially investigated by previous reports suggesting different time points for the hormone and receptor gene duplications...

INTRODUCTION: Examination of the gut-liver axis came into the spotlight worldwide. Liver enzyme elevations are commonly seen in patients with inflammatory bowel disease (IBD), which is a diagnostic challenge in everyday clinical practice. Liver and biliary diseases are common extra-intestinal manifestations in Crohn's disease and ulcerative colitis. The assessment of routine liver function tests could be an inaccurate reflection of liver damage, so its prevalence could be underestimated...

Hemorrhagic fevers caused by viruses were identified in the late 1950s in South America. These viruses have existed in their hosts, the New World rodents, for millions of years. Their emergence as infectious agents in humans coincided with changes in the environment and farming practices that caused explosions in their host rodent populations. Zoonosis into humans likely occurs because the pathogenic New World arenaviruses use human transferrin receptor 1 to enter cells. The mortality rate after infection with these viruses is high, but the mechanism by which disease is induced is still not clear...

PURPOSE: Recurrence is a major clinical problem in patients with pulmonary embolism and can affect mortality. The decision to discontinue treatment is important for recurrence and is based on patients' clinical features as well as certain blood parameters. Our aim in this study was to evaluate whether mean platelet volume (MPV) and platelet distribution width (PDW) have utility as new predictive parameters for recurrence and mortality in pulmonary embolism. MATERIALS AND METHODS: A total of 440 patients with pulmonary embolism underwent computed tomography, Doppler ultrasonography, and echocardiography before and at the conclusion of treatment...

BACKGROUND/AIM: Acetylsalicylic acid (ASA) treatment in diabetic patients is very important owing to the increasing hyperactivity of thrombocytes and atherosclerosis. In several investigations, it was reported that diabetes caused increased coronary artery disease, cerebrovascular disease, and death. In this study, we aimed to investigate the effect of ASA on osmoregulation, glycemic control, and some biochemical parameters in rats induced with experimental diabetes type 2. MATERIALS AND METHODS: Twenty-four rats were randomly divided in four groups: control (I), ASA control (II), diabetic (III), and ASA diabetic (IV)...

It is now well understood that thrombocytes (nucleated platelets) express TLRs and respond to both bacterial and viral products. Release of proinflammatory molecules can be expected following relatively short exposure times to LPS, lipoteichoic acid (LTA), thymidine homopolymer phosphorothioate oligonucleotide [Poly(dT)], and polyinosinic-polycytidylic acid [Poly(I:C)]. This study reports the varied expressions of genes encoded for components of the TLR, nucleotide binding oligomerization domain-like receptor, and retinoic acid-inducible gene RIG-like receptor signaling pathways in response to the TLR ligands listed above...

Rapid clinical triage of radiation injury patients is essential for determining appropriate diagnostic and therapeutic interventions. We examined the utility of blood cell counts (BCCs) in the first three days postirradiation to predict clinical outcome, specifically for hematologic acute radiation syndrome (HARS). We analyzed BCC test samples from radiation accident victims (n = 135) along with their clinical outcome HARS severity scores (H1-4) using the System for Evaluation and Archiving of Radiation Accidents based on Case Histories (SEARCH) database...

Millions of patients around the world suffer minor or major extremity amputation due to progressive wound healing complications of chronic or infected wounds, the therapy of which remains a challenge. One emerging therapeutic option for the treatment of these complicated wounds is the local application of an autologous thrombocytes concentrate lysate (e.g. platelet-released growth factors ((PRGF)) or Vivostat PRF(®)) that contains a multitude of chemokines, cytokines and growth factors and is therefore supposed to stimulate the complex wound healing process...

Dactylogyrus ctenopharyngodonid and Ichthyophthirius multifiliis are two important ectoparasites of freshwater fish. Co-infection by the two parasites leads to high fish mortality and results in heavy economic losses. This study aimed to evaluate the efficacy of medicated feed and a ginger extract bath against D. ctenopharyngodonid and I. multifiliis on grass carp and investigate the hematological response of grass carp co-infected by the two parasites. These results demonstrated that red blood cell (RBC) and thrombocyte percentage among leucocytes significantly decreased after grass carp were co-infected by D...
