For the human species, thermography has stood out as a diagnostic tool for breast cancer. However, its clinical benefit in bitches remains unknown. Thus, the goal of the present study was to evaluate the diagnostic applicability of infrared thermography for canine mammary tumors, as well as to correlate tumor temperature with mitotic index and tumor volume. Thermographic and digital images of eight bitches with mammary neoplasms were captured. Thermograms were entered into the FLIR tools software and the temperature of 15 tumor and 15 healthy glands from the contralateral mammary chain was analyzed. There was no significant difference (p = 0.786) between the mean temperature of neoplastic (33.71°C±1.86) and healthy (33.54°C±1.59) glands. There was a negative and moderate correlation between tumor temperature and mitotic index (ρ= -0.52 p = 0.049). However, no correlation was detected between mammary temperature and tumor volume (p = 0.10). Although thermography allowed no distinction between neoplastic and healthy mammary glands in bitches, it may be promising to assess the proliferative rate of tumors. In addition, malignant neoplasms may be more often hypothermic than healthy tissue.","PeriodicalId":38626,"journal":{"name":"Acta Veterinaria Brasilica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47552277","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}

Bee pollen samples were collected from the experimental apiary of the Study Group on Bees from the Semiarid Region of Piaui (GEASPI/UFPI) and subjected to melissopalynological analysis to determine their botanical origins, and bromatological analysis (crude protein, lipids, fibers, and ash) in the Laboratory of Animal Nutrition of the Department of Zootechnics of the Federal University of Piaui (UFPI), in Teresina, Piaui (DZO/UFPI/Teresina). Six plant species (Aspilia sp., Senna obtusifolia,Mimosa pudica L., Cupheaericoides, Croton sp., and Mimosa caesalpiniifolia) were predominant for bee pollen production in the study area. Therefore, the nutritional compositions of the pollen produced in the Caatinga area varied according to their botanical origin, as shown by the crude protein (20.75% to 38.18%), fiber (0.53% to 1.37%), lipid (0.49% to 4.7%), and total mineral (2.56 to 4.17%) contents. Bromatological parameters also varied according to the botanical origin of the pollens evaluated. The study region has considerable diversity of pollinator plant species that provide bee pollens with a wide spectrum of nutritional characteristics.","PeriodicalId":38626,"journal":{"name":"Acta Veterinaria Brasilica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45085857","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 animals are versatile and used in several sports because of major investments made for the genetic improve-ment of the breed. In recent decades, advances in molecular techniques enabled the identification of genetic diseases in hor-ses. Conducting molecular tests and determining the occurrence of mutations are fundamental for the early identification and prevention of abnormalities. Among the known genetic diseases that occur in horses, the c.926G>A mutation in the GYS1gene that causes type 1 polysaccharide storage myopathy (PSSM1) stands out, because it has been identified in several breeds of horses. Although myopathy is common in MM horses, the occurrence of the c.926G>A mutation in the GYS1 gene has not yet been evaluated. The lack of knowledge about the possible presence of PSSM1 averts the adoption of control measures to prevent the spread of the disease in MM horses. Therefore, the aim of this study was to verify the occurrence of the muta-tion that causes PSSM1 in MM horses used in breeding programs. Blood DNA was extracted and the region of the GYS1gene containing the mutation was amplified and sequenced. No mutation in the GYS1 gene was found in the evaluated sam-ples. However, since clinical signs of myopathy are frequently observed in MM horses, further studies, including histological analysis, are necessary to establish the underlying causes. In addition, if there is a genetic pattern of occurrence, molecular studies should be considered.","PeriodicalId":38626,"journal":{"name":"Acta Veterinaria Brasilica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45028213","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}

It was reported by owner that the animals had a history of poor weight gain and decreased food intake. C. macropomum that weighed around 1.5 kg were clinically evaluated where the body surface, fins, buccal and brachial cavity were carefully analyzed and no changes were found. N. buttnerae was the only intestinal parasite found in the specimens studied, and its distribution pattern showes a preference for the posterior portion of the intestine of C. macropomum. All 50 fish examined were parasitized by at least one N. buttnerae. This parasite was found in the digestive system of the examined fish. 100% of prevalence, 430 of intensity, 8.6 of average intensity and average abundance were found. Although there was no record of mortalities due to acanthocephalosis, damage that compromised the feed conversion of the fish was recorded. C. macropomum were infected by ingesting a crustacean containing cystacanth, the infective larval form of the parasite. Damage, such as presence of nodules, hypertrophy of goblet cells, thickening of the muscle layer, metaplasia in muscle tissue, severe edema from leukocyte infiltration in blood vessels and necrotic foci, were found in the intestine due to high infection rates of N. buttnerae. That said, inspection activities are essential for the preservation of consumer and animal health.","PeriodicalId":38626,"journal":{"name":"Acta Veterinaria Brasilica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45522625","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}

Therefore, the aimed is to characterize the macro and microscopic morphology of posterior digestive system of A. gigas. The intestine of six specimens A. gigas in ideal slaughter size was analyzed. The analyzes were performed using light-sheet microscopy (LM) and scanning electron (SEM) techniques. The intestine basically showes similar histological characteristics in three analyzed portions (proximal, middle and distal). Same type of simple columnar epithelium with goblet cells was evidenced, with subtle variations in pattern of villi in each segment, and in number of goblet cells. In the rectum, the amount of goblet cells and evident longitudinal villi was expressive. Macroscopic anatomy and histology of the intestine A. gigas analyzed showes characteristics of adaptation to cultivation, according to their diet and habitat. The intestinal mucosa can divided into three distinct portions: proximal, middle and final intestine, in addition to the rectum and anus. In the pyloric cecum, the folds are slightly higher and poorly branched. The rectum, compared to the midgut, showed a higher occurrence of goblet cells in the mucosa. This increase in goblet cells observed in the posterior portion may related to the assimilation of ions and fluids that occur at this location.","PeriodicalId":38626,"journal":{"name":"Acta Veterinaria Brasilica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43111092","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}
