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.
A Semantic Model for Socially Aware Objects  [PDF]
Giulia Biamino
Advances in Internet of Things (AIT) , 2012, DOI: 10.4236/ait.2012.23006
Abstract: The Internet of Things (IoT) assumes that things interact and exchange information thus defining the future of pervasive computing environments. The integration between people and interconnected objects realizes a new physical and social space and opens new frontiers in context awareness and objects adaptation. In this paper we investigate the possibility of creating socially aware objects able to interact not only among themselves but also with human beings sharing the same environment. The main contribution of this work is to provide a knowledge model for social context-awareness and reasoning using an ontology-based context modeling, a user model and exploiting of social networks. This model is part of a larger framework called So Smart that aims at empowering networks of interconnected objects with social context awareness in order to improve their social interaction with people.
The Dialogue and the Relationship with Parents and Friends: A Research on Italian Adolescents’ Representations  [PDF]
Giulia Savarese
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.74066

The goal was to understand what representations Italian adolescents have about the dialogue and the relationship with their parents and with the peer group, as well as to evaluate any differences. We interviewed 400 Italian adolescents, 200 males and 200 females, aged between 14 and 19 years. The instruments used were an ad hoc questionnaire and a free story. The results show significant differences in the communicative/relational support by parents and by the peer group, especially in relation to the confidences of their personal problems, the choice autonomy and the behaviors that encourage independence.

Everolimus Associated with Activated Vitamin D for Post-Transplant Increase Epstein-Barr-Virus Load Treatment. Two Case Reports  [PDF]
Luciano Moscarelli, Giulia Antognoli
International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.37119

Post-transplant lymphoproliferative disease (PTLD) is an uncommon but life-threatening complication of solid-organ and blood stem-cell transplants. It is caused by an uncontrolled expansion of B lymphocytes infected with Epstein-Barr virus (EBV). It responds poorly to therapy, including reduction of immunosuppression, interferon, antivirals or chemotherapy. Therefore the optimal strategy for management is currently focused on prevention. Some centers have already introduced chemoprophylaxis and/or preemptive strategies using EBV viral load as a surveillance. Some experimental studies suggest that mTOR inhibitors inhibits growth of human EBV-transformed B lymphocytes and vitamin D had an immune response to EBV. We report two cases of an increased of blood BKV viral load after renal transplantation that were successfully treated with everolimus in association with calcitriol. This report suggests that everolimus associated with calcitriol could be an effective and safe treatment for the prevention of PTLD in transplant recipients.

Jüdische Frauenvereine als Teil der europ ischen Frauenbewegung Jewish Women’s Organizations as Part of the European Women’s Movement
Nicolai Hannig
querelles-net , 2006,
Abstract: Der vorliegende Sammelband gibt einen fundierten Einblick in die unterschiedliche Entwicklung der jüdischen Frauenbewegung vom 19. bis ins 20. Jahrhundert. Im Zentrum der sechs Beitr ge stehen verschiedene Frauenvereine sowie deren Zusammensetzung und T tigkeitsfelder in Deutschland, sterreich und der Schweiz. Deutlich wird, dass vor allem Wohlt tigkeit und Fürsorge wichtige Aufgabenbereiche diverser Vereine darstellten; aber auch wirtschaftliche, rechtliche und politische Emanzipation spielten eine wichtige Rolle. Abgerundet wird dieser lesenswerte Tagungsband durch einen knapp 80 Seiten starken Quellenteil. The collection at hand provides a sound look into the different developments of the Jewish women’s movement from the nineteenth and into the twentieth century. Various women’s organizations as well as their composition and areas of activity in Germany, Austria, and Switzerland are central to the six contributions. The essays clearly show that charity and aid comprise the most important activities for many of the organizations, although economic, legal, and political emancipation also play an important role. An approximately 80-page appendix of sources rounds out this collection, which is truly well worth reading.
La lettera del vescovo Basilio di Roman nel contesto del conflitto tra il Metropolita Geronzio ed il Grande Principe Ivan III
Nicolai Zagnat
Codrul Cosminului , 2010,
Abstract: A letter addressed by the Bishop Vasile of Roman to Gerontius, the Metropolitan of Moscow, reflects an early dialogue between the Romanian and the Russian ecclesiastic hierarchy. It is one of the oldest evidence on the relations of the Romanian Church (or "Metropolitan of the Lower Country of Moldova") with the Russian Church (or the Metropolitan of Moscow). The letter appears in the context of misunderstanding between the grand prince of Muscovy, Ivan III, and Gerontius, the Metropolitan of Moscow. During the consecration of the cathedral "Uspenia" in Moscow, the Metropolitan has surrounded the church with all his ministers’ council, against the sun. The prince of Moscow was dissatisfied by this ordinance and started the conflict with the highest priest.
New Linear Systems for 2D Poincare Supergravities
H. Nicolai
Physics , 1993, DOI: 10.1016/0550-3213(94)90432-4
Abstract: A new linear system is constructed for Poincar\'e supergravities in two dimensions. In contrast to previous results, which were based on the conformal gauge, this linear system involves the topological world sheet degrees of freedom (the Beltrami and super-Beltrami differentials). The associated spectral parameter likewise depends on these and is itself subject to a pair of differential equations, whose integrability condition yields one of the equations of motion. These results suggest the existence of an extension of the Geroch group mixing propagating and topological degrees of freedom on the world sheet. We also develop a chiral tensor formalism for arbitrary Beltrami differentials, in which the factorization of $2d$ diffeomorphisms is always manifest.
Relativistic Effects in Quantum Entanglement
Nicolai Friis
Physics , 2010,
Abstract: One of the most fundamental phenomena of quantum physics is entanglement. It describes an inseparable connection between quantum systems, and properties thereof. In a quantum mechanical description even systems far apart from each other can share a common state. This entanglement of the subsystems, although arising from mathematical principles, is no mere abstract concept, but can be tested in experiment, and be utilized in modern quantum information theory procedures, such as quantum teleportation. In particular, entangled states play a crucial role in testing our understanding of reality, by violating Bell inequalities. While the role of entanglement is well studied in the realm of nonrelativistic quantum mechanics, its significance in a relativistic quantum theory is a relatively new field of interest. In this work the consequences of a relativistic description of quantum entanglement are discussed. We analyze the representations of the symmetry groups of special relativity, i.e. of the Lorentz group, and the Poincar\'e group, on the Hilbert space of states. We describe how unitary, irreducible representations of the Poincar\'e group for massive spin 1/2 particles are constructed from representations of Wigner's little group. We then proceed to investigate the role of the Wigner rotations in the transformation of quantum states under a change of inertial reference frame. Considering different partitions of the Hilbert space of 2 particles, we find that the entanglement of the quantum states appears different in different inertial frames, depending on the form of the states, the chosen inertial frames, and the particular choice of partition. It is explained, how, despite of this, the maximally possible violation of Bell inequalities is frame independent, when using appropriate spin observables, which are related to the Pauli-Ljubanski vector, a Casimir operator of the Poincar\'e group.
