Inflammatory Bowel Diseases: What Do We Still Need to Investigate?  [PDF]
Marina Taus, Debora Busni, Daniele Fumelli, Arianna Paci, Giulia Nicolai, Albano Nicolai
Open Journal of Gastroenterology (OJGas) , 2015, DOI: 10.4236/ojgas.2015.510024
Abstract: Inflammatory bowel disease (IBD) including Crohn (CD) and ulcerative colitis (UC), is intestinal disorders with an unknown specific etiology. Many factors are involved in the pathogenesis: genetic, environment, nutrition, immunity and intestinal dysbiosis. In the present work, we review the most important trigger mechanisms involved in IBD, with a particular regard to the role of microbiota and fecal mass transplantation as a new therapeutic approach, that even if it can be considered safe and effective, data are necessary regarding all procedures not yet standardized and timing of treatment.
Coeliac Disease: Gluten Free Diet and… What Else?  [PDF]
Marina Taus, Elsa Veronica Mignini, Daniele Fumelli, Debora Busni, Giulia Nicolai, Carla Carletti, Albano Nicolai
Open Journal of Gastroenterology (OJGas) , 2016, DOI: 10.4236/ojgas.2016.611035
Abstract: Coeliac Disease (CD) is a permanent gluten intolerance, whose pathogenesis involves multiple factors including genetics and environment. CD has different representations and non-specific symptoms such as diarrhea, bloating, pain, flatulence and constipation may sometimes be misleading. Once diagnosed of CD, patients must adhere to Gluten Free Diet, which consists in the lifelong avoidance of gluten containing foods and of those naturally gluten free but at risk of contamination. This dietary approach is considered the only therapy in order to avoid symptoms exacerbation and to reduce the digestive mucosa inflammation, which has been related to higher risks of lymphoproliferative malignancy and other immunological disorders. However, being on a Gluten Free Diet is not as resolving as it may seem since it has several criticalities. First of all, excluding gluten means limiting food variety so that coeliac patients may have unbalanced intake of several nutrients and develop clinical or subclinical deficiencies. This can be due to scarce attention to qualitative and quantitative composition of diets and poor information about gluten-containing foods, which only patient-tailored dietetic protocol and long-term follow-up can achieve. Secondly, Gluten Free Diet may not result in complete remission of mucosal damage or in resolution of symptoms. Unintentional contamination of gluten or poor adherence to diet are the main culprits of the incomplete mucosal healing but other triggers may be involved. Recent research has focused on the role of FODMAPs in changing gut microbiota and on the improvement of Irritable Bowel Syndrome (IBS) symptoms after their dietary avoidance or reduction. Since CD and IBS may share many clinical presentations, further studies are needed to evaluate if a subgroup of CD patients whose symptoms are not improved by Gluten Free Diet could benefit from a new therapeutic approach consisting in both gluten/wheat and FODMAPs avoidance.
é possível desenvolver a autorreflex?o no estudante de primeiro ano que atua na comunidade? um estudo preliminar
Prearo, Alice Yamashita;Monti, Fernanda Miranda Fumelli;Barragan, Elena;
Revista Brasileira de Educa??o Médica , 2012, DOI: 10.1590/S0100-55022012000100004
Abstract: in a multiprofessional, discipline-based curriculum with cumulative and cognitive assessment, anew discipline based on university-community service interaction (iusc), for medicine and nursing students at a s?o paulo school, aimed at finding a way to evaluate students' development of communication and self-reflection skills. overall assessment of students in small groups conducted through written reports and group portfolios failed to demonstrate self-reflection on the learning process in some students. a pilot study was therefore proposed, involving 15 students, divided into two randomly-selected groups, who agreed to develop an individual and reflective portfolio. qualitative analysis of the material outlined categories such as reflection on student life before the chosen university course began, life experiences that led the student to the chosen career, correlation between learning the subject and professional practice and ability to identify their growth in communication skills, indicating an efficient process of self-reflection on their learning.
Ten Years of the Central Italy Electromagnetic Network (CIEN) Continuous Monitoring  [PDF]
Cristiano Fidani, Daniele Marcelli
Open Journal of Earthquake Research (OJER) , 2017, DOI: 10.4236/ojer.2017.62004
Abstract: A test is being realised by means of a network of wide band electromagnetic detectors that continuously records the electric components of the electromagnetic field, ranging from a few of Hz to tens of kHz. The network has been operating in central Italy for more than ten years. The recorded signals from this network have been analysed in real time as well as their power spectrum contents. Time/frequency data have been saved for further analysis. The spectral contents have evidenced very distinct power spectrum signatures in ELF band that increase in intensity when strong seismic activity occurs near the stations, for example, at the time of Amatrice (M = 6) and Norcia (M = 6.5) earthquakes in 2016 when ten stations were operative, at the time of the Emilia (M = 6) earthquakes in 2012 when nine stations were operative, and at the time of the L’Aquila (M = 6.3) earthquakes in 2009 when only two stations were operative. Strong signals were also detected during the moderate Ancona (M = 5) earthquake in 2013 and by the recently installed Avigliano Umbro, Città di Castello and Gubbio stations in the Umbria region, during small seismic swarms (2 < M < 4) between 2013 and 2014. CIEN is presently composed of 16 stations and collect data from a multidisciplinary instrumentation.
Monitoring and Identification of the Seismically Isolated “Our Lady of Tears” Shrine in Syracuse  [PDF]
Daniele Losanno, Mariacristina Spizzuoco
Open Journal of Civil Engineering (OJCE) , 2018, DOI: 10.4236/ojce.2018.84028
Abstract: This paper describes the installation and management of the monitoring system of the “Our Lady of Tears Shrine” in Syracuse, whose dome is an imposing r.c. and prestressed r.c. structure of about 22,000 ton that was seismically isolated by flat sliding devices with hysteretic dampers. The monitoring system, representing an upgrading and improvement of an old system never made working, has some innovative features, because it allows to manage with the same dedicated hardware and software both the slow (thermal variations, relative humidity, wind direction and velocity) and the fast acquisitions (dynamic vibrations by wind and earthquake). The monitoring system was inserted among those structures maintained and controlled by the Seismic Observatory of Structures of the National Department of Civil Protection. Some records of low magnitude earthquakes allowed to validate the correct behaviour of the whole structure, as well as to make a dynamic identification of the complex construction and to calibrate a detailed finite element model of the Sanctuary, thus predicting isolators’ behaviour under design earthquake.
Self gravitating cosmic strings and the Alexandrov's inequality for Liouville-type equations
Daniele Bartolucci,Daniele Castorina
Mathematics , 2014,
Abstract: Motivated by the study of self gravitating cosmic strings, we pursue the well known method by C. Bandle to obtain a weak version of the classical Alexandrov's isoperimetric inequality. In fact we derive some quantitative estimates for weak subsolutions of a Liouville-type equation with conical singularities. Actually we succeed in generalizing previously known results, including Bol's inequality and pointwise estimates, to the case where the solutions solve the equation just in the sense of distributions. Next, we derive some \uv{new} pointwise estimates suitable to be applied to a class of singular cosmic string equations. Finally, interestingly enough, we apply these results to establish a minimal mass property for solutions of the cosmic string equation which are \uv{supersolutions} of the singular Liouville-type equation.
A global existence result for a Keller-Segel type system with supercritical initial data
Daniele Bartolucci,Daniele Castorina
Mathematics , 2015,
Abstract: We consider a parabolic-elliptic Keller-Segel type system, which is related to a simplified model of chemotaxis. Concerning the maximal range of existence of solutions, there are essentially two kinds of results: either global existence in time for general subcritical ($\|\rho_0\|_1<8\pi$) initial data, or blow--up in finite time for suitably chosen supercritical ($\|\rho_0\|_1>8\pi$) initial data with concentration around finitely many points. As a matter of fact there are no results claiming the existence of global solutions in the supercritical case. We solve this problem here and prove that, for a particular set of initial data which share large supercritical masses, the corresponding solution is global and uniformly bounded.
Assessment of debris flow magnitude in small catchments of the lombardy alps: the val gola case study  [PDF]
Daniele de Wrachien, Stefano Mambretti
Agricultural Sciences (AS) , 2011, DOI: 10.4236/as.2011.21002
Abstract: Debris flows are among the most destructive of all water-related disasters. They mainly affect mountain areas in a wide range of morpho- climatic environments. Therefore, accurate pre-diction of their run out distances, magnitudes and velocities plays a role of paramount impor-tance, in order to plan and design appropriate structural and non-structural defence measures. In this context, a number of Authors have de-veloped methods feasible to evaluate the ten-dency of a catchment to generate debris flow, without giving an estimation of the magnitude. Other empirical procedures are based on the analysis of historical series of debris flow, oc-curred in similar environments, to assess the relationship between the catchment character-istics and the maximum movable debris vol-umes. In this paper, and with reference to Val Gola—a small catchment in the North-East Lom- bardy where debris flows frequently occur—a number of methods, belonging to each of the above mentioned categories, have been briefly reviewed and applied in order to evaluate their effectiveness and consistency.
Challenges and Constraints in Irrigation and Drainage Development: A World-Wide View  [PDF]
Marco Medici, Daniele De Wrachien
Voice of the Publisher (VP) , 2016, DOI: 10.4236/vp.2016.22002
Abstract: In order to increase food production it is necessary to better understand all the factors underlying short term operations and long term strategies that lead to improve food security. In this regard any good effect deriving from agricultural research is strictly connected to a more accurate estimation of crops resources requirements, to major improvements in the use of irrigation and drainage systems, to a better understand of climatic variability. All the variables involved show strong dependency on both place and time. The failing of past, present and future systems can be essentially attributed to poor agricultural research planning, to incorrect agricultural systems design and resource allocation and to a not complete capacity to cope with short and long-term global climatic behavior.
