The GSH-Px activity of blastocysts, obtained from oocytes matured in low temperature, cultured in antioxidants-free embryo media was similar to blastocysts obtained from oocytes matured in conventional temperature, cultured in antioxidants-supplemented embryo media. The results of the present study show that decreasing the in vitro maturation temperature decreases antioxidant enzyme activity in both oocyte and blastocyst. Additionally, maturation of bovine oocytes at 36.5°C incubation temperature may provide an optimal thermal condition for the enzymatic antioxidant system of both oocytes and blastocyst.Centroblastic lymphoma (CBL) is the most common type of lymphoma in dogs and it usually responds well to chemotherapy. The aim of the study was to provide useful prognostic factors for dogs with CBL. Data regarding sex, breed, age, signalment, treatment and clinical course of the disease from 52 dogs diagnosed with centroblastic lymphoma (CBL) with cytology and immunocytochemistry were provisionally collected and related to the treatment outcome and survival. More than 80% of dogs were treated with chemotherapy and achieved complete remission in 80% of cases. Among the prognostic factors positively related to the overall survival time of dogs with CBL were the application of chemotherapy, achieving a complete remission, application of at least one additional chemotherapeutic agent to the basic protocol, especially the administration of mitoxantrone and asparaginase. Moreover, mitotic count 14 or higher measured in cytological slides in the area of 2,37 mm2 have been linked to shorter overall survival in dogs with CBL.Nickel damages the male reproductive system. We investigated the beneficial effects of silibinin which has metal-chelating and antioxidant properties over nickel toxicity. Both antioxidative effects in testes and overall effects related to sperm motility, membrane and acrosome integrity of orally administered Silibinin were evaluated against the harmful effects of 30 day of intraperitoneal nickel sulfate (5 mg/kg/day) administration in rats. Male rats were randomized into control (Group1; n=6) and three experimental groups (n=6, each) Group2 Nickel sulfate (5 mg/kg/day), Group3 Silibinin (150 mg/kg/day), and Group 4 Nickel sulfate (5 mg/kg/day) + Silibinin (150 mg/kg/day). We found higher sperm motility, viable sperm and total sperm count in Groups 3 and 4 than the Group 2 treatment groups and the percentage of abnormal spermatozoa was similar in both groups (Groups 2 and 4). Increased apoptosis, activation of caspase3, 8, 9 and TUNEL were detected in Group 2. However, activation of caspase3, 8, 9 and TUNEL was reduced in Group 4. The protective effects of silibinin were demonstrated on histopathologic findings and some sperm parameters (sperm motility percentage, viable spermatozoa, sperm count, and abnormal spermatozoa percentage) in rats exposed to nickel.Alveolar macrophages (AMs) are not only important immune cell of the host, but also important target cell of a variety of respiratory pathogens. They play an important role in defense against pathogen invasion and in maintaining tissue balance. Interferon (IFN)-γ is a well known multipotent cytokine that has antiviral and antibacterial immune activity and enhances antigen presentation. To better reveal the biological processes of porcine AMs activated by IFN-γ, transcriptomic analysis was performed using Illumina HiSeqTM technique. The results identified 2,248 differentially expressed genes (DEGs), of which 753 were upregulated and 1,495 were downregulated, in porcine AMs 12 h after IFN-γ stimulation, compared with mock-treated porcine AMs. A gene ontology function enrichment analysis of these DEGs indicated that these genes were significantly enriched in functional clusters such as immune response, defense response, and intracellular signaling cascades. Analyzing the Kyoto Encyclopedia of Genes and Genomes pathways of the DEGs showed that these genes are mainly involved in cytokine-cytokine receptor interactions, alpha linolenic acid metabolism, and the RIG-I-like receptor signaling pathway. This study shows that a massive gene expression change occurred in porcine AMs following IFN-γ stimulation, which is critical for understanding the mechanisms of IFN-γ-mediated macrophage activation and immune regulation.The last biomonitoring study in Poland on intoxication with fluoride compounds of deer was conducted almost two decades ago. Given the fact that fluoride level in air and water is not widely monitored in Poland, it is justified to undertake monitoring of F- levels in people and other long-lived mammals. This paper provides the assessment of the present level of fluoride accumulation in mineralized tissue of large herbivorous mammals. The aim of the present study was to determine fluoride concentration in teeth of deer inhabiting the areas of Poland which are industrially uncontaminated with fluoride compounds, to establish possible correlations between the analysed parameters, and to provide a comparison of the present results with those obtained in other studies. Mean concentration of fluoride in all analysed samples amounted to 231.0 F mg/kg, with the minimum value of 22.0 F mg/kg and the maximum of 935.0 F mg/kg. This results from the development of industry and a widespread use of fluoride-supplemented caries prevention products which contributes to an intense accumulation of these substances in vertebrates, predominantly in mineralized tissue.The aim of the study was to determine biologic variations of the main parameters in cows in early lactation and to compare intra-individual variations of parameters in cows and other species. 50 cows were included in the experiment. Blood samples were taken at the moment of calving, then on 1st, 7th, 14th and 28th day after calving. CVi had the following values 1.9-5% for MCV, MCH, MCHC, GLU, TProt, ALB, UREA, Ca, P and Mg; 5.1-10% for RBC, Hgb, Hct, WBC, NEU, LYM, BHB, ALT, CHOL, TGC and >10% for PLT, NEFA, TBil, AST and GGT. For RBC, Hgb, Hct, MCV, MCH subject-based reference values or the reference change value should be used. For all other parameters except AST, population-based reference intervals should be used with caution. For LYM, NEU, PLT, GLU, TProt, ALB, CHOL and TGC index of individuality was close to 0.6 which means that subject-based reference values can be much more adequate to use then population-based reference intervals. For AST population-based intervals should be used. There is little effect of parity (increase CVi with parity) and no effect of milk production. CVi values obtained in cows in early lactation are specific because they deviate from the CVi values of other animal species and human. Calculated RCVs varied from 5.5% for MCHC to 41% for AST. High individuality index for many metabolic parameters opens possibility for development of model for longitudinal monitoring of metabolic status of individual animals during lactation. That requires further research.The aim of this study was to determine prevalence of undesirable bacteria and their antimicrobial profile in samples obtained from a productive farm situated in border region Slanské vrchy (Slovakia), involved in keeping sheep and goats for the purpose of processing raw milk to special products (cheeses). Genus and species identification was carried out by PCR method and MALDI -TOF MS. Isolates thus identified were detected for antimicrobial resistance using the Agar Dilution Method. Bacteria of Staphylococcus spp. exhibited the highest resistance to penicillin (98% isolates). Isolates from the family Enterobacteriacae showed the highest resistance to azithromycin (90%). At the same time, in isolates of Enterococcus spp. we detected high resistance to linezolid (100%). Our investigation showed that all tested strains were resistant to more than one antibiotic used in this study.The purpose of the present work is to investigate the effect of dietary-supplemented artichoke (Cynara scolymus L.) on the mRNA expression of calbindin 1 (Calb1), osteopontin (Spp1), albumin (Alb) and CALB1 protein in the eggshell gland (ESG) of laying hens. A total of 80 ISA Brown hens (each at 40 weeks of age) were randomly divided into two groups a control and a treated group. All poultry received 130 g/day of compound feed for laying hens but the treated hens' diet was also supplemented with 3g/kg of dried and milled artichoke (Cynara scolymus L.). The increase of the Ca content in blood of the treated hens was established. Significantly decrease of Spp1 mRNA transcripts was found in the eggshell gland of the treated hens, while the mRNA level of Alb was increased. The relative expression of Calb1 mRNA tended to increase in the treated group. The expression of calbindin protein in the cytoplasm of glandular cells of the shell gland was defined by immunohistochemical method. Very strong signals of calbindin were observed in the treated group. The supplementation of the laying hens' diet with dried artichoke (C. scolymus L.) led to a significant increase of Ca content in blood that was reflected in the changes of expression of the eggshell gland genes involved in the mineralization of eggshell.Essential oils from plants used in traditional medicine are known as a rich source of chemically diverse compounds with specific biological activities. Achillea millefolium essential oil (AEO) was screened for in vitro activity against Babesia canis. The AEO was obtained by hydrodistillation and analysed by gas chromatography coupled to mass spectrometry (GC-MS). GC-MS revealed the presence of 47 compounds in the essential oil. Those present in the highest concentrations were chamazulene (34.45%), β-caryophyllene (8.93%), (E)-germacrene D (7.55%), patchoulene (7.27%), β-guaiene (4.62%), α-humulene (4.59%), santolina epoxide (4.41%), ethyl iso-allocholate (2.97%), aromadendrene (2.62%), and neoclovenoxid-alkohol (2.46%). AEO was found to be active in vitro against B. canis, with 50% inhibitory concentration (IC50) values of 0.06 mg/mL, as compared to imidocarb, with IC50 = 0.007 mg/mL. The study confirms that essential oil from A. Enfortumab vedotin-ejfv mw millefolium has anti-babesial properties in vitro.In this study, we developed a SYBR Green I real-time PCR method for the rapid and sensitive detection of novel porcine parvovirus 7 (PPV7). Specific primers were designed based on the highly conserved region within the Capsid gene of PPV7. The established method was 1,000 times more sensitive than the conventional PCR method and had a detection limit of 35.6 copies. This method was specific and had no cross-reactions with PCV2, PCV3, PRV, PEDV, PPV1, and PPV6. Experiments testing the intra and interassay precision demonstrated a high reproducibility. Testing the newly established method with 200 clinical samples revealed a detection rate up to 17.5% higher than that of the conventional PCR assay. The established method could provide technical support for clinical diagnosis and epidemiological investigation of PPV7.Prolonged exposure to stress may cause adverse effects on animal physiology. It is especially important during the gestation period as female physiology can affect the unborn offspring in the form of prenatal stress. Intensive pig farming industry developed gestation crates that enable to keep sows during gestation period in small stalls which do not allow animals to move freely for a maximum of 4 weeks after successful insemination (Council Directive 2008/120/EC). Although these crates have production advantages, many health and welfare issues have been raised recently. In this study we tested to what extent the lack of movement of sows kept in the gestation crates had an impact on some blood and saliva constituents of new-born piglets. In total, the samples were collected from 80 piglets when they were 3, 7 and 21 days of age and tested for cortisol levels in blood and saliva, acute phase proteins (amyloid A, C-reactive protein, haptoglobin) and lymphocytes proliferation index (in response to ConA, PHA and PWM).
