Serum calcium and inorganic phosphorus in blood of dairy cows in early and mid lactation were significantly lower compared to the values in the blood serum of dairy cows in late pregnancy, probably indicating the increased use of these macro elements by the mammary gland at the early stages of lactation. When the cows were in the lactation period, blood serum magnesium levels were significantly lower compared to the values of dairy cows during late pregnancy, probably indicating the increased use of magnesium by the dairy cows during lactation. The results show that the homeostasis of the macro elements examined in the blood of transition and mid lactation dairy cows was maintained, suggesting their adequate supply from alimentary sources.","PeriodicalId":30435,"journal":{"name":"Veterinarski Glasnik","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49319445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to determine the content of radionuclides and toxic elements in samples feedstuffs and food of animal origin collected between 2007- 2017 from two suburban areas of Belgrade, the municipalities of Palilula and Surcin, both areas with intensive agricultural production. Materials and Methods. Radionuclides (40K and 137Cs) and toxic elements (As, Cd, Cu, Ni, Pb and Zn) were determined in samples of corn, hay, meat, milk and eggs, by gamma ray spectrometry and inductively coupled plasma spectrometry (ICP-OES, Spectro Genesis). Results and Conclusions. The obtained results showed that natural 40K was present in all investigated samples. The average activity concentration of 40K was 94 Bq/kg in corn, 117 Bq/kg, 108 Bq/kg and 95 Bq/kg in beef, pork and chicken meat, respectively, as well as 61 Bq/kg in cow?s milk and 48 Bq/kg in eggs. Anthropogenic radionuclide 137Cs was not detected. The trend for toxic element levels according to the average concentrations found in the studied feed samples (corn and hay) was as follows: Zn>Cu>Pb>As>Ni>Cd. Arsenic was detected in animal feed in both Belgrade municipalities, with the average concentration being 1.08 mg/kg (0.5-1.37 mg/kg), and in corn, the As content was higher than in hay samples. In food of animal origin, only Zn and Cu were detected. It is concluded that the presence of radionuclides and toxic elements in feedstuffs and foods of animal origin does not pose a health risk for either humans or animals.","PeriodicalId":30435,"journal":{"name":"Veterinarski Glasnik","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45261168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The general condition of the affected animal was unchanged. According to the results of laboratory analysis, the cow was negative for the presence of antibodies against the bovine leukemia virus, showed a negative reaction in tuberculinization and was vaccinated against lumpy skin disease virus. After the surgical excision of one skin node, the sample tested negative for the genome of lumpy skin disease virus. In order to establish the morphology of the skin lesion, a histopathological analysis was performed. Histopathological analysis showed the infiltration of the corium and subcutaneous tissue by numerous mononuclear cells showing cellular atypia. Suspicion of cutaneous lymphoma was established. Furthermore, the immunohistochemical examination confirmed that the infiltrate contained exclusively CD3-immunopositive cells, suggesting a T-cell origin nonepitheliotropic lymphoma.","PeriodicalId":30435,"journal":{"name":"Veterinarski Glasnik","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44771710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Complete feed mixtures for laying hens are formulated to meet the requirements of the animals, for which various recommendations exist. Because of its nutritive value, feed provides a favorable environment for the growth of microorganisms. Prominent bacterial pathogens in poultry feed include Salmonella, Escherichia coli, Enterococcus, and Clostridium. There is a strong link between poultry feeds contaminated with bacteria pathogenic to humans and food borne disease occurrence, due to the feed-poultry-food-human chain. Materials and Methods. A total of fifty samples of complete feed mixtures for laying hens were collected during 2018 as a part of official controls. Feeds were analyzed for crude protein, crude ash, crude fat, crude cellulose, calcium and phosphorus, total numbers of bacteria, numbers of molds, Salmonella spp. and sulfite-reducing clostridia. Results and Conclusions. The feeds contained total bacteria and molds each at the level of 103 cfu g-1. Additionally, no Salmonella spp. or sulfite-reducing clostridia were detected in any feed sample. Saprophytic bacteria are frequently found in complete feed mixtures, but rarely are present in numbers considered as microbiologically unsafe. However, the presence of saprophytic bacteria can decrease the nutritive value of feed. The total number of bacteria and molds below the regulatory limits, as well as absence of pathogens in the commercially available poultry feed, indicates a high level of compliance with regulation. Furthermore, these results indicate the adequate implementation of controls and supervision of these poultry feed products in the Serbian market.","PeriodicalId":30435,"journal":{"name":"Veterinarski Glasnik","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48165237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mechanisms that regulate nuclear size and the functional significance of this regulation are largely unknown. Nuclear size and morphology are often altered in many diseases, such as cancer. Therefore, understanding the mechanisms that regulate nuclear size is crucial to provide insight into the role of nuclear size in disease.Scope and approach: The goal of this review is to summarize the most recent studies about the mechanisms and functional significance of nuclear size control using the Xenopus model system. First, this review describes how Xenopus egg extracts, embryos, and embryo extracts are prepared and used in scientific research. Next, the review focuses on the mechanisms and functional effects of proper nuclear size control that have been learned using the Xenopus system.Key findings and conclusions: Xenopus is an excellent in vivo and in vitro experimental platform to study mechanisms of nuclear size control. Given its close evolutionary relationship with mammals and that most cellular processes and pathways are highly conserved between Xenopus and humans, the Xenopus system has been a valuable tool to advance biomedical research. Some of the mechanisms that regulate nuclear size include components of nuclear import such as importin α and NTF2, nuclear lamins, nucleoporins, proteins that regulate the morphology of the endoplasmic reticulum, and cytoskeletal elements.","PeriodicalId":30435,"journal":{"name":"Veterinarski Glasnik","volume":"72 1","pages":"1-13"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/a1/c7/nihms-995326.PMC6242335.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36704633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
