Cerquetella,Matteo; Laus,Fulvio; Speranzini,Fabiana; Carnevali,Cristina; Spaterna,Andrea; Battaglia,Edda; Bassotti,Gabrio;
Revista Espa?ola de Enfermedades Digestivas , 2012, DOI: 10.4321/S1130-01082012000200004
Abstract: recurrent episodes of self-limiting diarrhea in the dog, due to sudden dietary changes and to stressful or exciting situations, are conditions sometimes difficult to treat. colifagina?, a commercially available bacterial enterovaccine, showed, in previous studies performed on experimentally induced colitis in mice, to be able to improve both disease activity index and histological appearance, increase colonic secretion of iga, and reduce inflammatory chemokine secretion. in the present study colifagina? was administered to five dogs presenting recurrent episodes of self-limiting diarrhea and to one dog presenting chronic diarrhea. during the follow-up period, almost all patients decreased the number of episodes of abnormal defecation and the fecal score of such episodes improved in five out of six dogs. even if further studies are needed to understand the exact potential of the compound, in dogs presenting recurrent episodes of self-limiting diarrhea due to sudden dietary changes and/or stressing or exciting situations, colifagina? seems to be helpful in managing most of these patients.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.462.469
Abstract: To evaluate the efficacy of enrofloxacin and N-acetylcysteine combination in the treatment of recurrent bronchopneumopathies caused by biofilm producer bacteria, a total of 30 dogs with recurrent respiratory diseases were examined. Bronchoalveolar lavage fluid of each animal was submitted to bacteriological and cytological examinations. Twelve patients have been treated with the above mentioned combination orally or by using an aerosol. Three dogs were randomly selected to be orally treated with Enrofloxacin only and another group of three animals has been randomly chosen to test the treatment with N-acetylcysteine only. Moreover, the in vitro sensitivity towards a panel of antibiotics for both biofilm and not biofilm producing bacteria was evaluated and correlation between bacterial sensitivity and biofilm production was evaluated. One animal was bacteriologically negative while biofilm producer bacteria have been identified in 19 (65.5%) out of the 29 bacteriological positive dogs. Biofilm formation and its abundance decreased bacterial sensitivity towards enrofloxacin (p<0.01) and cephalosporin (p = 0.031) while significant differences were not observed for the other classes of antibiotics. The association showed to be safe and effective in eliminating biofilm producer bacteria from all treated animals.
Inflammatory bowel disease in the dog: Differences and similarities with humans
Matteo Cerquetella, Andrea Spaterna, Fulvio Laus, Beniamino Tesei, Giacomo Rossi, Elisabetta Antonelli, Vincenzo Villanacci, Gabrio Bassotti
World Journal of Gastroenterology , 2010,
Abstract: Inflammatory bowel diseases (IBD) represent important chronic conditions affecting the gastrointestinal tract in man. However, similar disorders are found in several animal species and the IBD affecting dogs are particularly important. These are encompassed by an umbrella of probably several different entities with common symptoms, some of which seem to share striking similarities with human conditions. This review will focus on the actual knowledge of IBD in dogs, and attempt to identify differences and similarities with human IBD conditions.

Andrea Marchegiani, Ferdinando Nicoletti, Maria Rosaria Romano, Decio Capobianco, Ciro Costagliola, Carlotta Marini, Giuseppe Lubrano Lavadera, Roberto Ciccocioppo, Andrea Spaterna
Journal of Biomedical Science and Engineering (JBiSE) , 2019, DOI: 10.4236/jbise.2019.127028
Abstract: Background: Citicoline and homotaurine are compounds with a potent neuroprotective activity and they have been administered for many years in the treatment of numerous neurodegenerative and ophthalmological diseases, including glaucoma. Initially available only as liquid form, through parenteral route, nowadays citicoline can be administered also as tablet but no data on bioavailability of these different forms are available. In the present study, pharmacokinetics of citicoline in tablet versus vials, each at the therapeutic dose of 500 mg, in addition to 50 mg of homotaurine was investigated. Materials and methods: Ten mixed breed dogs received a single dose of 50 mg oral homotaurine and 500 mg citicoline in tablet and vials with the same dose were administered after a seven days wash-out period. Parameters assessed for citicoline metabolites (cytidine, uridine and choline) were AUC0t, Cmax and Tmax. Results: Citicoline bioavailability appeared to be slightly higher for the tablet compared to the vial formulation. Cytidine is equivalent in absorption dynamics both for tablet and liquid form; uridine for tablet reaches its maximum and is reabsorbed more quickly while choline for the liquid form reaches the maximum first and is reabsorbed more quickly. Conclusions: Citicoline in tablet and liquid formulation have pharmacokinetic properties leading to a very similar bioavailability.
Applications of Quantitative Serum Neopterin Determination in Dogs Affected by Leishmaniasis-Preliminary Study
Cerquetella Matteo,Spaziante Daniele,Laus Fulvio,Beribe Francesca,Marini Carlotta,Preziuso Silvia,Cuteri Vincenzo,Spaterna Andrea,Tesei Beniamino
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.3937.3942
Abstract: The aim of the present study was to evaluate possible correlations between Neopterin serum values and Immunofluorescence Antibody Test (IFAT) titers in dogs positive for Leishmania infantum and to provide further reference values for Neopterin in seronegative patients. Neopterin has been determined in 74 dogs, 30 of which where clinically healthy, seronegative and without any particular laboratory abnormalities for the tested parameters while the remaining 44 were positive to IFAT. The heterogeneous results obtained for Neopterin values in seronegative dogs in the present study did not allow inferring reference limits in those subjects but some of the correlations between Neopterin and IFAT titers in seropositive ones encourage further studies on that matter, possibly comparing the molecule values with other traditional markers of infection/disease. The present study represents a possible preliminary step towards the use of serum Neopterin values as a biomarker in dogs affected by leishmaniasis.
Integration of Highly Qualified Sub-Saharan Immigrants in Prague  [PDF]
Andrea Gerstnerová
Sociology Mind (SM) , 2011, DOI: 10.4236/sm.2011.12006
Abstract: Successful integration of immigrants into the host society demands a creation of specific conditions that would facilitate immigrants their adaptation to a new sociocultural, economic and political environment. Therefore, the process of integration itself is not only a task for immigrants, but also for a majority. One of the key factors for a creation of truly cohesive society is the support of positive aspects of mutual inter-cultural relations. This could be reinforced by implementation of “adequate” integration programs adapted to the local context as well as sensible use of mass media. If the host society does not dispose of effective instruments to integrate its “own citizens”, it is generally difficult to create strategies for insertion of immigrants of different cultural backgrounds (such as Sub-Saharan Africans). Basic features of the integration process of Sub-Saharan Africans and political reactions of the major society were identified in Prague, Paris, London and Liege.
Undesired Excess Capacity and Equilibrium in an Advanced Market Economy  [PDF]
Andrea Pannone
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.411079
Abstract:

In this paper I attempt to give theoretical foundation to the concept of undesired excess capacity that I define as an unwilling, persistent mismatch between productive capacity and final demand. Undesired excess capacity has traditional room only in oligopolistic framework, like in Keynesian and Post-Keynesian models. Otherwise I show the possibility of its existence (and persistence) also with reference to a perfectly competitive economy where firms use massively information and communication technologies (ICT). In this stylized economy, undesired excess capacity is associated with “ex-post sunk costs, in terms of mismatch between total revenues and production costs. My approach, which draws a production theory alternative to the neoclassical one, makes it possible to account for these costs and connect them to the role of money, under the form of credit, in the continuation of the economic process. Moreover, in the conclusion of this paper, I show how the notion of equilibrium that emerges from the analysis could be useful to address the issue of dynamics.

Lerner Index, Productive Efficiency and Homotheticity  [PDF]
Andrea Mantovi
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.53042
Abstract: Chambers et al. (2014) set forth a decomposition of the Lerner index, which results in a function on the full space \"\"?of input and output prices and quantities, such that the effect of the Farrell output measure of technical efficiency is explicit. In close correspondence, a decomposition of the Lerner index is established in which allocative efficiency (in both standard and reversed form, as defined by Bogetoft et al., 2006) complements the effect of input technical efficiency, with the reversed decomposition bound to the hypothesis of homotheticity. The resulting functions on \"\"are conjectured to define pregnant perspectives on the benchmark relevance of homothetic models, and their generalizations to multiple output.
Spherical Casimir Effect for a Massive Scalar Field on the Three Dimensional Ball  [PDF]
Andrea Erdas
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.68115
Abstract: The zeta function regularization technique is used to study the Casimir effect for a scalar field of mass m satisfying Dirichlet boundary conditions on a spherical surface of radius a. In the case of large scalar mass, \"\", simple analytic expressions are obtained for the zeta function and Casimir energy of the scalar field when it is confined inside the spherical surface, and when it is confined outside the spherical surface. In both cases the Casimir energy is exact up to order \"\"and contains the expected divergencies, which can be eliminated using the well established renormalization procedure for the spherical Casimir effect. The case of a scalar field present in both the interior and exterior region is also examined and, for \"\", the zeta function, the Casimir energy, and the Casimir force are obtained. The obtained Casimir energy and force are exact up to order \"\"and \"\"respectively. In this scenario both energy and force are finite and do not need to be renormalized, and the force is found to produce an outward pressure on the spherical surface.
