Hypophosphatemic osteomalacia associated with tenofovir: a multidisciplinary approach is required.

Mediterranean Journal of Hematology and Infectious Diseases , 2012, DOI: 10.4084/mjhid.2012.
Abstract: Tenofovir is widely used as first-line treatment of HIV infection, although its use is sometimes complicated by a reversible proximal renal tubulopathy. We report the case of a 45-year-old woman with chronic HIV infection and personality disorder, who after 12 months of tenofovir, complained of fatigue, diffuse bone pain and gait disturbances. The elevated level of alkaline phosphatase, hypophosphatemia and inappropriate phosphaturia suggested the diagnosis of hypophosphatemic osteomalacia secondary to proximal renal tubulopathy. A dual-energy x-ray absorptiometry showed a bone mineral density below the expected range for age (lumbar spine Z-score -3.3, femoral neck Z-score -2.1). A whole body 99mTc-methylene diphosphonate bone scan showed multiple areas of increased focal activity in the lumbar and thoracic spine and in sacroiliac and hip joints consistent with pseudo-fractures. Two months after tenofovir discontinuation and administration of vitamin D and phosphate, osteomalacia-related symptoms disappeared. Eleven months later, bone and mineral metabolism data were normal and bone scintigraphy did not show any pathological findings. This report highlights the importance of considering the diagnosis of osteomalacia in patients treated with tenofovir and emphasizes the need for monitoring alkaline phosphatase, blood and urinary phosphate and creatinine, especially in patients with risk factors for bone disease.
The Universe at Lattice-Fields  [PDF]
Giovanni Guido, Gianluigi Filippelli
Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) , 2017, DOI: 10.4236/jhepgc.2017.34060
Abstract: We formulate the idea of a Universe crossing different evolving phases \"\" where in each phase one can define a basic field at lattice structure (Uk) increasing in mass (Universe-lattice). The mass creation in Uk has a double consequence for the equivalence “mass-space”: Increasing gravity (with varying metric) and increasing space (expansion). We demonstrate that each phase is at variable metric beginning by open metric and to follow a flat metric and after closed. Then we define the lattice-field of intersection between two lattice fields of base into universe \"\" and we analyse the universe in the Nucleo-synthesis phase (intersection-lattice \"\" ) and in the that of recombination (intersection-lattice \"\" ). We show that the phase \"\" is built on the intersection of the lattices of the proton (Up) and electron (Ue) or \"\" . We show UH to be at variable metric (open in the past, flat in the present and closed in the future). Then, we explain some fundamental aspects of this universe UH: Hubble’s law by creating the mass-space in it, its age (13.82 million of Years) as time for reaching the flat metric phase and the value of critic density. In last we talk about dark universe lattice \"\", having hadronic nature, and calculating its spatial step \"\" and its density in present phase of \"\" .
Variational Principle in an Expanding Universe  [PDF]
Giovanni Guido, Gianluigi Filippelli
Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) , 2018, DOI: 10.4236/jhepgc.2018.41016
Abstract: In this paper we complete the relativistic cosmological theory because we extend the variational principle including variations of metric induced by expansion of the space. We will show that the mass not only curves Space and Time but also generates them: we’ll speak of the principle of mass-space equivalence. Then the increasing mass generates variations of metric as also the space increasing or expansion. So, the dark component of the mass generates additional gravity around galaxies as well as additional space, which generates a pressure (dark energy) accelerating the galaxies in their move away. All this could explain the cosmic coincidence (Ωdm/Ωde ≈ 1). To talk about the increasing mass is equivalent to speak of mass creation in universe, causing the variation of the tensor (T) mass-energy tensor of all component fields. We conjecture that its variation is caused by mass-energy flow comes out from a physical system (Θ) composed by set of uncoupled quantum oscillators (structure of no-field) in vacuum state. All this allows formulating a variational principle which generates the cosmological equation with the (Λ) parameter and a tensor T* with variable mass density, where T*(T, Θ).

Law and Justice on TV. The Wire vs. CSI and Ally McBeal La legge e la giustizia in TV. The Wire a confronto con CSI e Ally McBeal
Gianluigi Rossini
Between , 2012,
Abstract: The aim of this paper is to analyse the ways in which law is represented in the celebrated TV series The Wire, broadcasted in United States between 2002 and 2008. The analysis focuses particularly on the thematization of the relationship between the concept of law and that of justice, that is between 'positive law' and 'natural law'. This theme is pursued in the context of American television series of great success such as CSI: Crime Scene Investigation (CBS, 2000-) and Ally McBeal (Fox, 1997-2002) . The comparison highlights the way in which in The Wire the terms of the problem are completely eroded through the representation of a sort of 'disappearance of justice'. In this series the natural law becomes insignificant both because it is no more the point of reference of the actions activated by the institutions, and because an informed, in-depth and not prejudicial gaze on the social reality of the contemporary metropolis brings into question the very idea of a justice absolute and distanced from the contingent circumstances. Scopo di questo intervento è individuare il modo in cui la legge è rappresentata in The Wire, serie poliziesca trasmessa negli Stati Uniti tra il 2002 e il 2008 da HBO. Particolare oggetto di interesse dell'analisi è la tematizzazione del rapporto tra il concetto di 'legge' e quello di 'giustizia', ovverosia tra la 'legge positiva' e la 'legge naturale'. Questa tematizzazione viene, però, inquadrata all'interno del contesto della serialità televisiva statunitense, analizzando in via preliminare il modo in cui lo stesso rapporto è trattato da altri due titoli di grande successo: CSI: Crime Scene Investigation (CBS, 2000- ) e Ally McBeal (Fox, 1997-2002). Dal confronto emerge come The Wire riesca a scardinare completamente i termini del problema, mettendo in scena una sorta di 'scomparsa della giustizia'. Nella serie la legge naturale, infatti, diventa irrilevante sia perché non è più il referente delle attività messe in moto dalle istituzioni, sia perché uno sguardo approfondito, informato e non pregiudiziale sulla realtà sociale delle metropoli contemporanee mette in discussione l'idea stessa di una giustizia assoluta e distaccata dalle circostanze contingenti.
Christine Baron e Manfed Engel (Eds.), Realism/Anti-Realism in 20th Century Literature
Gianluigi Rossini
Between , 2012,
Abstract: Parte della serie Internationale Forschungen zur Allgemeinen und Vergleichenden Literaturwissenschaft edita da Rodopi, il volume è composto da quattordici saggi, cinque dei quali in francese, i restanti in inglese. Come chiarisce sin dalle prime righe l'introduzione, l'obiettivo dell'opera non è né dare una definizione stringente di realismo né catalogare tutte le differenti modalità in cui, in letteratura, forme antirealistiche si sono opposte o intrecciate a quelle realistiche: questo non soltanto perché l'ambito è limitato al XX secolo, ma anche perché non viene imposta una prospettiva che permetta di inquadrare in un modello generale la dinamica tra le due forme di rappresentazione.

Between , 2011,
Abstract: In questo agile saggio Vittorio Coletti (ordinario di Storia della lingua italiana presso l'Università di Genova) intende definire i tratti di una mutazione avvenuta all'interno del romanzo contemporaneo, mutazione che ha comportato il superamento delle distinzioni e delle proprietà nazionali nella pratica della narrazione.
Familias interculturales en Espa a: análisis de la satisfacción vital Intercultural Families In Spain: An Analysis of Life Satisfaction
Gianluigi Moscato
Portularia : Revista de Trabajo Social , 2012, DOI: 10.5218/prts.2012.0004
Abstract: Uno de los fenómenos más relevantes por su dimensión, complejidad y actualidad, es el que se denomina matrimonio mixto o intercultural. Sin embargo los estudios relativos a la integración de estas familias en la comunidad y su calidad de vida son escasos. Se pretende analizar algunas de las variables relativas a la dimensión social y relacional capaces de predecir su satisfacción vital. Se opta por una metodología cuantitativa. Se administra el protocolo a una muestra compuesta por 95 familias interculturales seleccionada a través del metodo snow ball y se utilizan escalas validadas para analizar las distintas variables en cuestión. Atendiendo a la comparación entre espa oles y extranjeros, hay diferencias significativas solo en relación al sistema de apoyo social. Los análisis de regresión, muestran una relación de causa efectos sobre la satisfacción vital. En ambos casos, tanto las dimensiones relacionales como sociales, predicen la satisfacción vital. En el caso de los espa oles se trata de la satisfacción marital, satisfacción con el apoyo de la pareja y satisfacción con el apoyo de los amigos espa oles (F=20,5, p<.01). Mientras para los extranjeros se dan las mismas variables, que para los espa oles, con la a adida de la discriminación percibida ( =-.35) y el sentido de comunidad (F=19.5, p<.01. Proponemos un plan de formación y una intervención participativa, con el objetivo de establecer herramientas más eficaces en la mejora de la satisfacción vital de este colectivo. One of the most relevant phenomena, given their size, complexity and relevance, are the so-called mixed marriages or intercultural marriage. However, there are few studies about the integration of these families in the community and their quality of life. The objective of this paper is the analysis of a new family configuration through the social and relational dimensions as they are able to predict their life satisfaction. It uses quantitative methodology. The questionnaire was completed by a sample of 95 families selected through intercultural snow ball method and validated scales were used to analyze the different variables involved.The differences between Spaniards and foreigners are significant only in relation with the social support system. Regression analyses show a cause-effect relation on life satisfaction. In both cases, the relational and social dimensions predict life satisfaction. In the case of Spaniards, the explanatory variables are marital satisfaction, satisfaction with partner support and satisfaction with the support of Spanish friends (F = 20.5, p <.01). Fore
Time dependent quantum generators for the Galilei group
Gianluigi Filippelli
Mathematics , 2014, DOI: 10.1063/1.3621518
Abstract: In 1995 Doebner and Mann introduced an approach to the ray representations of the Galilei group in ($1+1$)-dimensions, giving rise to quantum generators with an explicit dependence on time. Recently (2004) Wawrzycki proposed a generalization of Bargmann's theory: in his paper he introduce phase exponents that are explicitely dependent by 4-space point. In order to find applications of such generalization, we extend the approach of Doebner and Mann to higher dimensions: as a result, we determine the generators of the ray representation in ($2+1$) and ($3+1$) dimensions. The differences of the outcoming formal apparatus with respect to the smaller dimension case are established.
Categorical Proof Theory of Co-Intuitionistic Linear Logic
Gianluigi Bellin
Computer Science , 2014, DOI: 10.2168/LMCS-10(3:16)2014
Abstract: To provide a categorical semantics for co-intuitionistic logic one has to face the fact, noted by Tristan Crolard, that the definition of co-exponents as adjuncts of coproducts does not work in the category Set, where coproducts are disjoint unions. Following the familiar construction of models of intuitionistic linear logic with exponential"!", we build models of co-intuitionistic logic in symmetric monoidal left-closed categories with additional structure, using a variant of Crolard's term assignment to co-intuitionistic logic in the construction of a free category.
