Profound acidemia impairs cellular and organ function and consequently should be associated with an increased risk of mortality in critically ill humans and animals. Neonatal diarrhea in calves can result in potentially serious metabolic derangements including profound acidemia due to strong ion (metabolic) acidosis, hyper-D-lactatemia, hyper-L-lactatemia, azotemia, hypoglycemia, hyperkalemia and hyponatremia. The aim of this retrospective study was to assess the prognostic relevance of clinical and laboratory findings in 1,400 critically ill neonatal calves with diarrhea admitted to a veterinary teaching hospital...

Platelet-released growth factors (PRGF) and its related clinically used formulations (e.g., Vivostat Platelet-Rich Fibrin (PRF®)) contain a variety of chemokines, cytokines, and growth factors and are therefore used to support healing of chronic, hard-to-heal, or infected wounds. Human beta-defensin-3 (hBD-3) is an antimicrobial peptide inducibly expressed in human keratinocytes especially upon wounding. The potent antimicrobial activity of hBD-3 together with its wound closure-promoting activities suggests that hBD-3 may play a crucial role in wound healing...

Autologous thrombocyte concentrate lysates, for example, platelet-released growth factors, (PRGFs) or their clinically related formulations (e.g., Vivostat PRF®) came recently into the physicians' focus as they revealed promising effects in regenerative and reparative medicine such as the support of healing of chronic wounds. To elucidate the underlying mechanisms, we analyzed the influence of PRGF and Vivostat PRF on human keratinocyte differentiation in vitro and on epidermal differentiation status of skin wounds in vivo...

BACKGROUND & AIMS: Patients with inflammatory liver disease commonly develop debilitating symptoms, called sickness behaviors, which arise via changes in brain function. Monocytes that produce tumor necrosis factor (TNF) interact with cerebral endothelial cells to activate microglial cells and promote sickness behavior. Platelets regulate inflammation, and aggregates of monocytes and platelets are increased in the circulation of patients with liver disease. We investigated the role of platelets in inducing inflammatory features of circulating monocytes and promoting sickness behaviors in mice with cholestatic liver injury...

The supplementation of culture medium with fetal bovine serum (FBS, also referred to as 'fetal calf serum') is still common practice in cell culture applications. Due to a number of disadvantages in terms of quality and reproducibility of in vitro data, animal welfare concerns, and in light of recent cases of fraudulent marketing, the search for alternatives and the development of serum-free medium formulations gained global attention. Here, we report on the 3rd Workshop on FBS, Serum Alternatives and Serum-free Media, where (a) regulatory aspects, (b) the serum dilemma, (c) alternatives to FBS, (d) case-studies of serum-free in vitro applications, and (e) the establishment of serum-free databases, were discussed...

Pituitary adenylate cyclase-activating polypeptide (PACAP) is an inhibitor of megakaryopoiesis and platelet function. Recently, PACAP deficiency was observed in children with nephrotic syndrome (NS), associated with increased platelet count and aggregability and increased risk of thrombosis. To further study PACAP deficiency in NS, we used transgenic Tg(cd41:EGFP) zebrafish with GFP-labeled thrombocytes. We generated two models for congenital NS, a morpholino injected model targeting nphs1 (nephrin), which is mutated in the Finnish-type congenital NS...

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: Endothelial dysfunction links thrombotic microangiopathy to steroid-refractory graft-versus-host disease (GVHD) after allogeneic stem-cell transplantation. We aimed to assess if the simple formula-lactate dehydrogenase (U/L) × creatinine (mg/dL)/thrombocytes (10(9) cells per L)-termed the Endothelial Activation and Stress Index (EASIX), might be valuable for the prediction of death in patients with acute GVHD after allogeneic stem-cell transplantation. METHODS: For this retrospective analysis, we analysed a training cohort (in Germany) and three validation cohorts (in Germany and the USA) of patients with acute GVHD who had received consecutive allogeneic stem-cell transplantation...

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...
