Copper is an important metal essential for scavenging free radicals, development of central nervous system (CNS) and redox angiogenesis signaling. Vascular endothelial growth factor (VEGF) is well known as efficacious and long-term signal that stimulates angiogenesis, where its expression is copper dependent. We examined the copper protective effect against brain vascular damage initiated by NDEA. NDEA induces brain vascular wall damage, necrosis with interstitial hemorrhage and diminishes VEGF expression. Histopathological examination showing a great improvement of brain tissue in copper treated mice with significant increase in VEGF expression. Higher levels of intracellular copper can stimulate angiogenesis and exhibited a significant protection against NDEA induced brain vascular damage, confirming its ability to enhance antioxidant activity and angiogenesis initiation. Our report presents first evidence that inducible VEGF expression in brain is sensitive to copper; moreover, copper-based therapeutics represents a novel approach to reduce brain vascular damage induced by NDEA generated ROS.","PeriodicalId":22190,"journal":{"name":"SVU-International Journal of Veterinary Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42763683","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}

A group of 20 adult male mice was divided into two groups for this purpose. The mice in group (I) are the controls, whereas the mice in groups (II) were exposed to formaldehyde vapors inhalation in a toxic dose (0.5 PPM) every day for two months in the students dissecting room of South Valley University's Faculty of Veterinary Medicine. Lung samples were prepared for light microscopic examination after exposure. Gross structural abnormalities in the lungs were identified, including congestion in most lobes and localized pneumonic organization. Thickening of the alveolar septum, epithelial hyperplasia in the bronchioles, proliferative capillaries, pulmonary vasculitis, and hyperplastic lymphocytic aggregations in the parabronchiolar area, pulmonary fibrosis, and precancerous modifications were detected under light microscopy (metaplasia of goblet cells and dysplasia of the bronchiolar epithelium). It was found that inhaling formaldehyde has an irritating toxic effect in addition to its harmful carcinogenic effect on the lungs of mice, which is related to exposure durations.","PeriodicalId":22190,"journal":{"name":"SVU-International Journal of Veterinary Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44016513","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}

Currently, a total number of 110 dairy cows from different regions of Qena governorate, Egypt, were clinically and laboratory investigated for diagnosis of theileriosis, babesiosis and anaplasmosis using Giemsa stained blood film and Polymerase Chain Reaction (PCR) assay during the period from January 2019 to December 2019. On the basis of the obtained results, the overall prevalence of theileriosis, babesiosis and anaplasmosis among the screened cattle was 21.81%, 9.09% and 25.45 respectively. Furthermore, mixed infections were seen in nineteen cases (17.27%) on the basis of blood film examination. PCR assay results revealed that, the infection rate with theileriosis, babesiosis and anaplasmosis was 5.12%, 10.25% and 35.89%, respectively. While, 3 cows (7.69%) were found to harbor a mixed infection. Additionally, hemato-biochemical alternations in theileriosis, babesiosis and anaplasmosis infected cows were also detected in this study. It could be concluded that PCR assay was the most sensitive test in the detection of the infection in all cases of the disease (acute, chronic and carriers) as once animals infected, they become carriers with low parasitemia after recovery and this low parasitemia cannot be detected by traditional examination of Giemsa stained thin blood smears.","PeriodicalId":22190,"journal":{"name":"SVU-International Journal of Veterinary Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42483114","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}
