A fibroadenoma was diagnosed in the left udder of a 3-month-old female Chios lamb. No recurrence was observed after surgery. Grossly, the tumor had a whitish-gray lobular appearance, and the lobules were interlaced with thin septa. Microscopically, the tumor was composed of proliferating fibroepithelial tissue, including differentiated ducts lined by whorls and interlacing bundles of abundant loose fibrovascular stroma. Immunohistochemistry revealed the ductal epithelium to be positive for pancytokeratin (AE1/AE3) and loose fibrovascular stroma was positive for vimentin and basal cells covering the ductal epithelium of alpha-smooth-muscle actin. Immunostaining for the estrogen and progesterone receptors was negative. A diagnosis of mammary fibroadenoma was made based on the histological and immunohistochemical findings. 相似文献

The objective of this study was to determine the loss of toxicity of deoxynivalenol in extruded cereal-based products by the tetrazolium salt (MTT) bioassay using a sensitive Chinese hamster ovary (CHO-K1) cell line and to compare the results to chemical (high-performance liquid chromatography, HPLC) and biochemical (enzyme-linked immunosorbant assay, ELISA) methods of analysis. A split-split plot design was used for the extrusion process experiments at temperatures of 150, 175, and 200 degrees C and screw speeds of 70 and 140 rpm. The initial mean deoxynivalenol concentration in the corn grits artificially contaminated with Fusarium graminearum was found to be 23.5 mug/g as measured by HPLC. The percent reductions of deoxynivalenol in the contaminated corn grits upon extrusion processing ranged from 22 to 35%, from 21 to 34%, and from 21 to 37% as measured by HPLC, ELISA, and MTT bioassay, respectively. The MTT bioassay results were more closely correlated with HPLC (r = 0.90) results than with ELISA results (r = 0.78). The MTT bioassay, using a sensitive mammalian cell line, was demonstrated to be a useful method for quantification of deoxynivalenol as well as a potential toxicity screening method for contaminated extruded cereal-based products. 相似文献

The present study describes immunophenotypic characteristics of inflammatory infiltrate in the skin and lung of lambs naturally infected with sheeppox virus (SPV). Three lambs revealed typical cutaneous and pulmonary lesions of sheeppox. Histologically, cutaneous and pulmonary lesions consisted of hyperplastic and/or degenerative changes in the epithelium with mononuclear cells, neutrophils, and typical sheeppox cells (SPCs), which had a vacuolated nucleus and marginated chromatin with occasional granular intracytoplasmic inclusions. The inflammatory infiltrate in pox lesions in both skin and lung was characterized by the presence of MHC II+ dendritic cells, CD4+, CD8+, gammadelta+ T cells, IgM+ cells, and CD21+ cells. Loss of expression of MHC I and MHC II antigens was observed in the affected areas of skin and lung. SPCs, stained with anti-SPV antibody, were also positive for CD14 and CD172A, antigens expressed on monocytes and macrophages. CD14 and CD172A negative SPCs were considered to be SPV infected degenerated epithelial cells or fibroblasts. 相似文献

SummaryThe aim of this study was the identification of those product characteristics that are important for the adoption of fruit and fruit product innovations by consumers. Sixteen focus group discussions were held in four European countries (Greece, The Netherlands, Poland, and Spain). Different aspects of six innovative fruit products were discussed, revealing those characteristics that were important for the adoption of each of them. It was observed that the participants did not perceive fruit innovations as a homogenous group, but assigned them to different groups, which led to a number of categories of fruit innovation. Three categories concerned the level of preparation of fruit. These were fresh, prepared, and processed fruit product innovations. Another two categories, radical and evolutionary innovations, related to the level of novelty of the fruit innovation. Characteristics important for the adoption of each of these categories are given. The results will be used for further, more quantitative, research. 相似文献

A female 8-month-old Simmental calf was presented with a history of a gradually enlarging mass in the ventral abdominal skin since 4 months of age. The mass was well circumscribed, lightly pigmented, and rough surfaced with many fine fissures and was attached to the skin by a relatively broad pedicle. On cut section, there was a border between the reddish-black stroma and overlying epithelium, including hemorrhagic foci of variable sizes. Histologically, the tumor was papillomatous with angiokeratomatous features and irregular hyperplasia with epidermal rete ridges and dilated vascular channels filled with blood in the superficial dermis. In the epidermis, orthokeratotic hyperkeratosis, variably sized keratohyalin granules, and many koilocytes, some of which had papillomavirus (PV) genus-specific structural antigen-positive nuclei, were also observed. Cells lining the dilated vascular spaces were positive for vimentin and alpha-smooth muscle actin but negative for factor VIII-related antigen, desmin, and PV. The lesion was regarded as an angiokeratomatous papilloma and was similar to other angiomatous lesions. 相似文献

Seed quality is one of the important objectives in cotton production and breeding. Seed-coat fragments (SCFs) and motes are the main impurities in lint cotton and are major concerns in the textile industry. A 2-year study was conducted to compare 10 cotton (Gossypium hirsutum L.) cultivars for the number of SCFs, motes, and resistance to loading force (RL). 相似文献

Liquid-phase transfer coefficients of ten selected organic pollutants were measured simultaneously with the O2 reaeration coefficient in a 2L reactor. The contents of the reactor were stirred in the laboratory by a 0.15 m diameter propeller attached to a constant speed motor. The ratio of the mass transfer coefficient of the chemical to that of O2 is found to vary between 0.43 and 0.60 for eight of the chemicals tested. This result is in good agreement with the literature concerning high volatility chemicals. The value of this ratio for the other two chemicals was found to be 0.10 for nitrobenzene and 0.01 for phenol, confirming the predominance of gas phase resistances in the transport process for these two compounds. 相似文献
