Parameters of Hemostasis in Sheep Implanted with Composite Scaffold Settled by Stimulated Mesenchymal Stem Cells-Evaluation of the Animal Model.

Implantation of composite scaffolds could be potentially associated with the risk of hemostatic disturbances in a recipient. However, there is a lack of information on possible alterations in clotting mechanisms resulting from such a procedure. The aim of the present work was to investigate changes in hemostatic parameters in sheep implanted with a scaffold composed of poly(ε-caprolactone) and hydroxyapatite and tricalcium phosphate (9:4.

Involvement of hemostasis in pathophysiology of RAO in horses.

Recurrent Airway Obstruction (RAO), also called severe asthma or heaves, is a chronic disease in adult horses caused by aeroallergens from straw or hay. Disturbances in hemostasis (intensified coagulation and depressed fibrinolysis) are considered one of the prominent reasons of inflammatory process, injury and dysfunction of the lungs. The aim of the study was to evaluate chosen parameters of hemostasis in horses with active form of RAO.

Low-level light therapy reduces platelet destruction during extracorporeal circulation.

Extracorporeal circulation causes many deleterious effects on blood cells. Low-level light therapy (LLLT) in the red/near-infrared spectral range is known for its cytoprotective properties but its use during cardiopulmonary bypass (CPB) has not yet been studied. We aimed to assess whether LLLT protects platelets during CPB.

Effect of antigen challenge on dynamics of CD62P and CD41/61 expression on platelets in horses with recurrent airway obstruction (RAO).

Recurrent airway obstruction (RAO), also known as heaves, is an allergic respiratory condition that develops in horses following an exposure to aeroallergens in hay and straw. This is manifested by airway hyperreactivity, inflammation, bronchoconstriction, as well as a leukocyte and platelet infiltration into the airways. Platelet activation and an increase in circulating platelet-leukocyte aggregates may lead to airway remodeling.

Investigation of the immune effects of on blood leukocytes and selected organs of the chicken's lymphatic system.

Background: The health of chickens and the welfare of poultry industry are central to the efforts of addressing global food security. Therefore, it is essential to study chicken immunology to maintain and improve its health and to find novel and sustainable solutions. This paper presents a study on investigation of the effect of root (SBR) on the immune response of broiler chicken, especially on lymphocytes and heterophils reactivity, regarding their contribution to the development of immunity of the chickens.

Age-related changes of platelet and plasma coagulation parameters in young pigs.

The literature on hemostatic processes in swine is sparse and often fragmentary; hence, we conducted our study to characterize age-related changes in selected parameters of primary and secondary hemostasis in 50 growing pigs between day 2 and week 24 of age. We measured platelet count (PLT), mean platelet volume, platelet-to-large cell ratio, prothrombin time, activated partial thromboplastin time (aPTT), thrombin time (TT), and fibrinogen concentration. Among primary hemostasis parameters, PLT underwent the largest fluctuation with the animals' age, ranging from 340 to 730 × 10(9)/L.

Expression of surface platelet receptors (CD62P and CD41/61) in horses with recurrent airway obstruction (RAO).

Recurrent airway obstruction (RAO) is an allergic disease of horses similar to human asthma, which is characterized by airway inflammation and activation of neutrophils, lymphocytes and platelets. Platelet activation and an increase in circulating platelet-leukocyte aggregates may lead to airway remodeling. The aim of this study was to investigate platelet status in RAO-affected horses based on the platelet morphology and platelet surface expression of CD41/61 and CD62P.

[Influence of gelatin-alginian matrixes on morphological and functional changes of blood leukocytes].

Background: Knowledge of the relation of biomaterials and living tissues constitutes necessary information which should be used when composing a set of optimal carriers, e.g. for drugs or preparations supporting blood clotting.

Polymerase chain reaction-based identification of clinically relevant Pasteurellaceae isolated from cats and dogs in Poland.

A set of polymerase chain reaction (PCR) assays for identification of the most important Pasteurellaceae species encountered in cats and dogs were developed. Primers for Pasteurella multocida were designed to detect a fragment of the kmt, a gene encoding the outer-membrane protein. Primers specific to Pasteurella canis, Pasteurella dagmatis, and Pasteurella stomatis were based on the manganese-dependent superoxide dismutase gene (sodA) and those specific to [Haemophilus] haemoglobinophilus on species-specific sequences of the 16S ribosomal RNA gene.

Genetic diversity of Pasteurella dagmatis as assessed by analysis of the 16S rRNA and rpoB gene sequences.

A total of 16 Pasteurella dagmatis strains, including 11 feline and 4 canine isolates as well as one strain isolated from a tiger, were analyzed using partial 16S rRNA and rpoB gene sequence comparison. Phylogenetic studies based on both genes revealed that the population of P. dagmatis recovered from cats in Poland differs markedly from canine strains, constituting a well-separated cluster within Pasteurella sensu stricto species group.

An acidic glycoconjugate from Lythrum salicaria L. with controversial effects on haemostasis.

Aim Of The Study: Lythrum salicaria L. belongs to the small Lythraceae family of 22 genera, which range in habit from herbs to shrubs and trees found with worldwide distribution (Heywood, 1993). The generic name of Lythrum derived from Greek "luthron"--blood, possibly referring to the color of the flowers or to the one of its herbal use as an astringent to stop bleeding (Thompson et al.
