Promozione e valorizzazione culturale e scientifica del patrimonio archeologico nel territorio del Polesine (provincia di Rovigo)
No full textThe Teknehub Laboratory (University of Ferrara), Area 2, stipulated a Memorandum of Understanding with the local authorities responsible for archaeology in the Veneto region about the accomplishment of a research work in cultural and scientific promotion and estimation of the Archaeological Heritage in the Polesine area (near the city of Rovigo).
The research mainly focused on:
- The implementation of a signage system along the Via Popilia, where ancient trails and archaeological finds are signposted and referenced to existing museums. Thanks to this action, a larger number of visitors will have the opportunity to enjoy the features of the archaeological heritage of this area and its sites.
- The appreciation of the archaeological site of San Basilio (Ariano nel Polesine), an ancient settlement which dates back to the VI century BC. The archaeological finds are preserved in the Centro Turistico Culturale, an organisation which carries out innovative concepts for visiting the archaeological site and implements a new idea of museum communication.
- The definition of a new reconstructive archaeological site in Frattesina, where finds are exposed in the Museo Archeologico Nazionale. In Fratta Polesine, the are currently no archaeological sites that can be visited, so the idea of building one would be interesting both in terms of enhancing the number of visitors to the museum itself, and for the development of a new concept of educational exhibition
Alterazioni polmonari della pleuropolmonite contagiosa bovina (PPCB) in fase esordiente. Aspetti istologici ed immunoistochimici
No full textRecent pulmonary lesions at slaughter in bovines affected by Mycoplasma mycoides during the years 1990-1993 in Northern Italy are reported. Several histologic and inimunocytochemical examinations showed that: - The earliest lesions of CBPP are foci of desquamative bronchiolo-alveolitis, - The highest concentration of the antigen is found in the cytoplasm of desquamated alveolar macrophages. From our results, we can exclude that CBPP begins with interstitial lesions as some authors have hypothesized. On the contrary, the hypothesis, formulated at the beginning of the century, that CBPP begins with a desquamative bronchiolo-alveolitis seems to be more convincing. Our results give some help to construct a correct pathogenesis of the disease
Some aspects of humoral and cellular immunity in naturally occurring feline infectious peritonitis
No full textHaematology, antibody titers and serum protein electrophoresis from 48 cats (34 effusive and 14 noneffusive forms) affected with feline infectious peritonitis (FIP) were studied and compared with those of 20 healthy cats. In the effusive form, antibody titers and protein electrophoresis in the effusions were analyzed. The distribution of the immune cells and of the virus in FIP lesions were also investigated immunohistochemically with the avidin-biotin complex (ABC) method, using antibodies against the FIP virus (FIPV), myelomonocytic (MAC387) and lymphoid (CD3, CD4 and CD8 for T-cells and IgM and IgG for B-cells) antigens. Seropositive animals (antibody titer>l:100) were present among both the FIP infected cats (73%) and the healthy cats (70%). Cats with effusive FIP had neutrophilic leukocytosis (P>0.05), lymphopenia (P<0.01) and eosinopenia (P<0.001). In both effusive and noneffusive forms decreased albumin/globulin ratio (P<0.001) with hypoalbu' minemia (P<0.001), hyperglobulinemia (P<0.001) and increased α2- (P<0.05), β- (P<0.05) and γglobulins (P<0.001) were found. Hypergammaglobulinemia was not related to the antibody titers, suggesting the presence of other proteins with γ-motility (e.g. complement fractions). The electrophoretic pattern of the effusions was always similar to that of the corresponding serum. Antibody titers higher than those of the corresponding serum were often detected in the effusions. Immunohistochemical findings were not related to the antibody titers, but they were related to the histological aspect of the lesions. In cellular foci of FIP lesions many virus-infected macrophages and few lymphocytes, mainly CD4+, were found. Extracellular viral and myelomonocytic antigens were also detectable in the loci with intercellular necrosis. Only few FIPV-infected cells were present at the periphery of the larger necrotic loci: in these lesions MAC387+ cells were mainly neutrophils, with many MAC387- macrophages, probably due to their activated state; a small number of lymphocytes, with an increasing percentage of CD8+ cells was present. Lymphocytes were more abundant when cellular foci and FIP-infected macrophages were centered around neoformed vessels. IgM and IgG exposing B-cells were always few and scattered. In conclusion the simultaneous analysis of body fluids and of the cellular composition of the lesions showed a complex immune status, on which type HI and type IV hypersensitivity could coexist
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Vascular lesions in Feline Infectious Peritonitis (FIP) are thought to be caused by a type III hypersenstivty reaction, while histology of the granulomas suggest a type IV hypersensitivity. To further investigate the pathogenesis of the disease we analized some aspects of humoral and cellular immunity in FIP. Haematology, antibody titers and protein electrophoresis in serum and in effusions from 48 FIP affected cats were studied. The results were compared with those of 20 healthy cats. The distribution of the immune cell and of the virus in FIP lesions were also studied by immunohistochemistry using antibodes against myelomonocytic (MAC387), and lymphoid (CD3, CD4 and CD8 for T-cells and IgM and IgG for B-cells) antigens.
Seropositive animals (antibody titer>1:100) were present either among the FIP infected cats (73%) either among the healthy cats (72%). FIP infected cats had neutrophilic leukocytosis (P>0.05), lymphopenia (P<0.05) and hyperglobulinemia (P<0.01) with increased 2 (P<0.05) and globulins (P<0.001). Hypergammaglobulinemia was not related to the antibody titers, suggesting the presence of other proteins with motility (e.g. complement fractions such as C1q). These changes were found either in effusive or in non effusive FIP. The electrophoretic pattern of the effusions was always similar to those of the corresponding serum. Antibody titers higher than those of the corresponding serum were often detected in the effusions. Immunohistochemical findings were not related to the antibody titers, but they were related to the histology of the lesions. In cellular foci of FIP lesions many virus-infected macrophages and few lymphocytes, mainly CD4+ve, were found. Extracellular viral and myelomonocytic antigen were also detectable in the foci with intercellular necrosis. Only few FIPV-infected cells were present at the periphery of the larger necrotic foci: in these lesions MAC387+ve cells were mainly neutrophils, with many MAC387-ve macrophages, may be due to their activated state: a mild number of lymphocytes, with an increasing percentage of CD8+ve cells were present. Lymphocytes were more abundant when cellular foci and FIP infected macrophages were centered around neoformed vessels. IgM and IgG exposing B-cells were always few and scattered.
In conclusion the simoultaneous analysis of body fluids and of the cellular composition of the lesions showed a complex immune status, on which type III and type IV hypersenstivty could cohexist
Zygomatic gland adenoma in a dog : histochemical and immunohistochemical evaluation
No full textOrbital epithelial tumors in dogs are rare and most frequently malignant. Distinguishing their origin from the lacrimal or zygomatic gland is often challenging and is based mostly on tumor location. A case of adenoma involving the orbit in a 13-year-old, female, standard Schnauzer is reported. Histologically, the neoplasm was characterized by nests and cords of epithelial cells mostly forming small glandular structures. The origin of the tumor from the zygomatic gland was determined by histochemical characteristics (alcian blue pH 1 positive staining) of a small remnant of normal gland included within the tumor capsule. The benign nature of our finding was confirmed by follow-up information: 2 years after complete surgical removal of the mass no tumor recurrence or metastases was recorded
