This report describes the first case of idiopathic hypertrophic osteopathy (HO) in a cat. No causes for the bone pathology were found following evaluation of the physical and laboratory examinations (complete blood count, albumin, creatinine, urea, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase and gamma-glutamyltransferase and urinalysis), and after histopathological evaluation of organs at necropsy. Based on the radiographic, clinical and anatomopathological findings, idiopathic HO was diagnosed.  相似文献

The decline of cork oak (Quercus suber) stands in Iberian Peninsula is associated with infection by Phytophthora cinnamomi. Most Phytophthora species secrete elicitins, which can enhance defence reactions against some pathogens. Here cytological and physiological effects of the elicitins cryptogein and capsicein on cork oak root infection by P. cinnamomi were evaluated. The progression of the pathogen in root tissue and its effects on total fatty acid (TFA) composition of roots and leaves were analysed in seedlings. Net photosynthesis (P _n ), stomatal conductance (g _s ), chlorophyll a fluorescence measurements (quantum yield of linear electron transport ? _e , photochemical quenching q _P, non-photochemical quenching NPQ) and carotenoid determinations were carried out in well established (4?months) plants. In elicitin-treated roots, 2?days after inoculation, the pathogen which presented loss of viability and membrane degradation was mainly restricted to the intercellular spaces of the cortical parenchyma, and did not reach the vascular cylinder. Electron dense materials accumulated in the intercellular spaces of the cortex next to disorganized hyphae, suggested to be related with defence reactions. Cryptogein (or its interaction with P. cinnamomi) induced enhanced lipid synthesis in leaves, which may contribute to preserve membrane stability. P. cinnamomi decreased P _n , g _s , ? _e , and q _P, whereas elicitin-treated plants displayed values similar to controls. Overall, the results indicated a resistance response of cork oak against this oomycete, induced by the elicitins.  相似文献   

Canine lymphoma and vector‐borne diseases: Molecular and serological evaluation of a possible complicity

Lymphoma is the most common haematological malignancy in dogs and its aetiology is largely unknown. The presence of canine vector‐borne agents (CVBD) in lymphoma tissues has been described and its causative effects questioned. We intended to evaluate the presence and extent of Leishmania infantum, Ehrlichia canis, Anaplasma phagocytophilum and Bartonella henselae infection in dogs with lymphoma. Sixty‐one dogs, living in the Lisbon metropolitan area, with a diagnosis of lymphoma were enrolled. Immunofluorescence assays were used to detect serum IgG's. The presence of DNA from CVBD agents in tumour tissue was assessed by PCR. All dogs tested negative for B. henselae, A. phagocytophilum and E. canis by both serology and PCR. Regarding L. infantum, 8.2% (n = 5) of the dogs had a positive serologic result. L. infantum DNA was detected in two samples of diffuse large B‐cell lymphoma (DLBCL). These results show an increased, but not significant, seropositivity (8.2% vs 7.9%) and molecular detection (3.3% vs 1.2%) for L. infantum in dogs with lymphoma, when compared to the reported canine population in the same geographical area. We could not identify an association between lymphoma and E. canis, A. phagocytophilum, B. henselae or Leishmania infantum infection in the studied population. Nevertheless, further studies, following dogs trough their CVBD disease evolution, are worthwhile and may help clarify a possible role of CVBD agents in lymphomagenesis.  相似文献   

Embryo Transfer Efficiency of Quarter Horse Athletic Mares     

Marcelo A. Pessoa  André P. Cannizza  Maria Fernanda S. Reghini  Marco Antônio Alvarenga 《Journal of Equine Veterinary Science》2011,31(12):703-705

This study was designed to compare embryo recovery rates and pregnancy rates of athletic and breeding Quarter Horse mares in a tropical warm climate. Thirty-nine barrel racing mares in training and 135 breeding mares as control donors were included. During the training period, the ambient temperature ranged from 31°C to 36°C and the average humidity from 70% to 90%. After the detection of a 35-mm follicle by ultrasound, ovulation was induced with 1 mg of deslorelin acetate (i.m), and insemination was performed 24 hours later with cooled and fresh semen from different fertile stallions. Embryos were collected on day 8 postovulation. The body temperature (rectal) was evaluated from eight athletic donor mares randomly selected from the same studied group. A total of 138 and 657 embryo collections were carried out on training and breeding mares, respectively, with a total of 105 (76%) and 466 (71%) embryos collected (P > .05). Similarly, no differences (P > .05) were observed for the pregnancy rates on day 15 (82/105, 78% vs. 370/466, 79%), and day 40 (73/105, 69% vs. 328/466, 70%) between the training and breeding donor mares. Just after training, the body temperature increased to an average of 39.4°C and the respiratory rate from 14.5 to 35.3 breaths per minute. The results of the present study showed that embryo production from appropriately trained donor mares in good condition were similar to non-athletic broodmares.  相似文献   

Immunohistochemical evaluation of MMP-2 and TIMP-2 in canine mammary tumours: a survival study   总被引：1，自引：0，他引：1

Canine mammary tumours (CMTs) are a very heterogeneous group of neoplasms with variable prognosis. Their aggressiveness is mainly due to their ability to invade locally and to metastasize. The degradation of extracellular matrix components is an important determinant of the invasive phenotype. The aims of this study were to analyse by immunohistochemistry and double immunofluorescence the expression of metalloproteinase 2 (MMP-2) and tissue inhibitor of metalloproteinase 2 (TIMP-2) in eight normal canine mammary glands and 118 CMTs (24 benign, 94 malignant) and to investigate relationships with metastatic disease and survival.MMP-2 and TIMP-2 expression was higher in malignant tumours than in normal canine mammary tissue and benign tumours. The main difference between benign and malignant CMTs was the pattern of expression of both molecules: benign tumours presented TIMP-2 and MMP-2 immunoreactivity in the myoepithelial cells lining the basement membrane of tubuloalveolar structures, while malignant tumours showed mainly diffuse expression in neoplastic cells. In malignant tumours, increased TIMP-2 expression was significantly associated with the development of distant metastases, lower overall survival and lower disease-free survival. MMP-2 expression was not significantly associated to any of these parameters. These results suggest that the immunohistochemical expression of TIMP-2 is a useful prognostic factor in CMTs.  相似文献

Biochemical modulations in açaí palm (Euterpe oleracea Mart.) under vegetative stages in an agroforestry system of the Amazon     

Gizele Odete de Sousa  Ismael de Jesus Matos Vigas  Jessivaldo Rodrigues Galvo  Susana Silva Conceio  Tiago Kesajiro Moraes Yakuwa  Mauro Junior Borges Pacheco  Thiago Costa Viana 《植物养料与土壤学杂志》2021,184(1):76-87

Background : The açaí palm (Euterpe oleracea Mart.) is a species native to the Amazon region, where the largest stock of these palms is located in the state of Pará, Brazil. This species occurs predominantly spontaneously in the plateau and plains areas of the Amazonian estuary. Water deficit is the main limiting factor of plants, negatively regulating the growth, metabolism and productivity of crops. Aim : This study aimed to deepen the ecophysiological and biochemical responses of Euterpe oleracea Mart. to a water deficiency condition in agroforestry systems. Methods : The study was carried out in a defined period of lowest rainfall in the region, which runs from July to October, averaging 58.6 mm for those months, such as location, age, uniformity, health, development, height and diameter of the stipe, in order to determine the biochemical variables. Responses to biochemical components under water deficit such as starch, sucrose and carbohydrates increased for rachis and fruits. Results : The concentrations of ammonia and proteins increased in stems and fruits. For amino acids, the structures that accumulated these organic compounds were fruits and arrow. One of the most representative amino acids against water deficiency is proline, and its increase in plant tissues is due to osmoprotein function, especially for structures such as rachis, fruit and petioles + rachis. Conclusions : Therefore, Euterpe oleracea Mart. presents excellent physiological plasticity to deal with stressful conditions as well as adaptive behavior to overcome this deficiency.  相似文献

European pennyroyal (Mentha pulegium) from Portugal: Chemical composition of essential oil and antioxidant and antimicrobial properties of extracts and essential oil     

Bárbara Teixeira  António Marques  Cristina RamosIrineu Batista  Carmo SerranoOlívia Matos  Nuno R. NengJosé M.F. Nogueira  Jorge Alexandre SaraivaMaria Leonor Nunes 《Industrial Crops and Products》2012,36(1):81-87

There is a growing interest of industry to replace synthetic chemicals by natural products with bioactive properties from plant origin. The aim of this study was to determine the chemical composition of European pennyroyal (Mentha pulegium) essential oil and to characterize the in vitro antioxidant and antimicrobial activities of its water (hot and cold) and ethanolic extracts and of the essential oil. The essential oil revealed menthone, pulegone and neo-menthol as the main constituents, comprising 35.9, 23.2 and 9.2% of the essential oil, respectively. The hot water extract exhibited the highest antioxidant activity and phenol content. In contrast, the extracts were not very effective to inhibit the growth of the seven foodborne spoilage and pathogenic bacteria tested, but the essential oil showed antibacterial activity against all bacterial strains. In conclusion, extracts and essential oil of M. pulegium from Mediterranean origin have huge potential as an alternative to chemical additives for the food industry.  相似文献
