Loeb’s formula: a rich though waisted heritage
Francesco Sgambato,Ester Sgambato,Armando Fucci
Emergency Care Journal , 2006, DOI: 10.4081/ecj.2006.4.20
Abstract: Loeb’s formula is one of the milestones in the practical demonstration that the human organism cannot be studied in a fragmented way and, through its application, one can, in a simple way, give immediate responses to different problems in both a diagnostic and therapeutic context. Loeb conducted experimental studies on the different “vital behaviour” of various animal organisms in contact with different saline solutions at various concentrations. His work on the induction of rhythmic contractions in skeletal muscles, for example, or those on the importance of the ionic equilibrium in the survival of various embryos, led him to claim that by modifying the ions contained in a tissue it is possible to transfer qualities not possessed ordinarily. The key to the problem, which he posed on a daily basis when studying microcellular living beings, was to determine the appropriate blend of such ions or better the “harmonious set” of the various salts in the correct concentrations such as to maintain vital conditions. Loeb’s studies yielded the first concrete demonstrations that the maintenance of vital conditions depends on a dynamic balance of contrasting dynamic ionic forces, kept in the correct proportions by an incredible system of automatic regulators. His experiments gave a more concrete explanation to the concept of “stability of the interior environment” by Claude Bernard (1813-1878) and contributed to the great scientific season of general physiology that took place in the late 19th and early 20th centuries. This fabulous “poker of aces” laid the foundations for “holistic” concepts, no longer in theoretical terms, but also with concrete “in vivo” demonstrations, subject to ongoing laboratory tests, in harmony with the canons of the “experimental” method.
Arts and Scholastic Performance  [PDF]
Arnaud Cabanac
Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.815163
Abstract: Pleasant environmental music during an academic test helped students to overcome stress. As a result the grades they obtained were higher. It was also demonstrated that students selecting music as optional course performed better, than music-less control students over three consecutive years. Yet, there remained ambiguities as for the causes of the higher test performance of these students. Our study confirmed a Mozart effect, and further showed a latency of two to three years for such a positive influence to take place, suggesting that it is the practice of music itself that helps cognition. We showed also that other art courses, when freely chosen, have similar positiveinfluences on students’ performances, illustrating that the principles of learning are linked to hedonism and to will effort in a more general manner.
Dissociation between Performances in Water Maze and Spontaneous Alternation in BALB/C versus A/J Mice  [PDF]
Julien Celestine, Arnaud Tanti, Arnaud Aubert
Journal of Behavioral and Brain Science (JBBS) , 2012, DOI: 10.4236/jbbs.2012.22018
Abstract: Learning processes are extensively studied in behavioral neuroscience. As experimental models, Morris Water Maze (MWM) and Spontaneous Alternation (SA) represent two of the most frequently used laboratory tests to respectively address spatial vs non-spatial tasks. Several factors have been shown to impact on those learning, including strain, gender, apparatus, conditioning, vision, lighting conditions and stress level. In order to focus on the later, we compared the acquisition of two learning tasks (MWM and SA) in BALB/c and A/J mice, which are known as fearful and stress-sensitive strains. Here, we report that BALB/c mice exhibited higher performances than A/J mice in the MWM (i.e. spatial reference memory task), whereas A/J mice performed better in the SA (i.e. spatial working memory task). These results indicate dissociated processes in the acquisition of spatial vs non-spatial tasks, and emphasize a varying influence of emotional reactivity on different forms of cognition.
Distinct Changes in cAMP and Extracellular Signal-Regulated Protein Kinase Signalling in L-DOPA-Induced Dyskinesia
Emanuela Santini,Veronique Sgambato-Faure,Qin Li,Marc Savasta,Sandra Dovero,Gilberto Fisone,Erwan Bezard
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0012322
Abstract: In rodents, the development of dyskinesia produced by L-DOPA in the dopamine-depleted striatum occurs in response to increased dopamine D1 receptor-mediated activation of the cAMP - protein kinase A and of the Ras-extracellular signal-regulated kinase (ERK) signalling pathways. However, very little is known, in non-human primates, about the regulation of these signalling cascades and their association with the induction, manifestation and/or maintenance of dyskinesia.
Soft tissue non-Hodgkin lymphoma of shoulder in a HIV patient: a report of a case and review of the literature
Domenico Marotta, Alessandro Sgambato, Simone Cerciello, Nicola Magarelli, Maurizio Martini, Luigi Maria Larocca, Giulio Maccauro
World Journal of Surgical Oncology , 2008, DOI: 10.1186/1477-7819-6-111
Abstract: The Authors report a case of a 34 year-old lady. In December 2003 the patient noted a painless mass on her right shoulder whose size increased progressively. In March 2004 she was diagnosed HIV positive and contemporary got pregnant. The patient decided to continue her pregnancy and to not undergo any diagnostic procedure and treatment. At the end of August she underwent a surgical ablation of the lesion that revealed a lesion of 7 cm × 7 cm × 3,3 cm. The histology showed B-cells expressing CD20, PAX-5, CD10, BCL-6 and MUM-1 with 70% Ki67 positive nuclei. The lesion was also negative for EBV infection and showed a monoclonal rearrangement of IgH chain and a polyclonal pattern for TCR gamma and beta. A final diagnosis of diffuse large B-cell lymphoma was made. The patient underwent postoperative chemotherapy. At four-years follow up the patient is symptom free and no local nor systemic recurrence of pathology has been noted on MRI control. HIV infection is still under control.In this report, we present a case of diffuse large B-cell lymphoma localized in the soft tissue of the shoulder in a HIV infected patient. Authors want to underline this case for the rare position, the big size and the association with HIV infection.The risk of developing lymphoma is greatly increased in HIV infection which induces a severe impairment of the immune system due to the progressive reduction of CD4 lymphocytes thus leading to the development of different infections and tumors. The improvement of the therapy with longer life expectancy has led to new associations and, among these, the involvement of other tissues such as the musculoskeletal system. Usually musculoskeletal lesions involve lower limb. Authors report a rare case of soft tissue lymphoma localized at right shoulder in a HIV-infected patient.A 37 years old lady (who was born in 1971) underwent a surgical goldbladder ablation and a excision of appendicitis in 2001. Two years later, in December 2003 the patient noted a painl
Criatividade, comunica??o e produ??o do saber

Abstract: knowledge production is a key element of the dynamics of contemporary societies that until now have been based on uneven levels of scientific and professional knowledge. the aim of this work is to understand, from a sociological point of view, the various aspects of the relationship between creativity, communication and knowledge production, starting from the following questions: what is the role of communication in the elaboration of discoveries or intellectual advances? what is the role of individuals and networks in these advances? and finally, what are the characteristics, especially the communicational ones, of the more creative institutions? the text is based on the works of philippe breton (communication and the status of knowledge), randal collins (network creativity), rogers hollingsworth (cognitive complexity, institutional diversity, quality of the research environment in terms of scientific exchange and discussion). these questions are not restricted to a strictly academic debate. they are also directly related to the practices of research environments, professors-researchers and students of master’s and doctor’s degree.
Um candomblé na Bélgica: tra?os etnográficos de tentativa de instala??o e suas dificuldades
Halloy, Arnaud;
Revista de Antropologia , 2004, DOI: 10.1590/S0034-77012004000200004
Abstract: in this article, i propose to go through some difficulties encountered in a setting up attempt of a candomblé (afro-brasilian cult) in belgium. my analysis will propose three main categories of problems: situations undermining the legitimation of the cult's chief and the respect of some ritual constraints; various "adaptation" attempts to human and material resources available; difficulties of learning some categories of knowledge that are not based on a linguistic formulation. to focus in this study on problematic situations does not aim to drow a chaotic picture of a "disrooted" cult but to account ethnographicaly for the dynamic and the multi-facial and builded characteristics of religious experience.
Les réseaux négociants de trois maisons huguenotes de Cadix, à la fin du xviiie siècle : des réseaux languedociens, protestants ou fran ais ?

Liame : Histoire et Histoire de l’Art des époques Moderne et Contemporaine de l’Europe Méditerranéenne et de ses Périphéries , 2012,
Abstract: Dans le dernier tiers du xviiie siècle, pour faire leur commerce, les négociants fran ais de Cadix – le port qui servait de tête de pont au commerce colonial espagnol – s’appuyaient sur deux types de réseaux marchands : d’une part, des correspondants résidant en Europe, qui leur fournissaient les biens manufacturés recherchés sur les marchés américains et qui recevaient, en échange, les piastres et autres denrées coloniales que les cargadores leur rapportaient en retour ; d’autre part, de...
L'affectivité et le comportement non verbal en classe de langue étrangère
Christine Arnaud
Synergies Espagne , 2008,
Abstract: Nous abordons dans cet article les aspects affectifs dansl’enseignement/apprentissage des langues étrangères et nous nous intéressonsplus précisément aux comportements non verbaux des apprenants et desenseignants. Nos réflexions sont basées sur la thèse de doctorat (Arnaud,1999) intitulée : Les enseignants et les apprenants en classe de langueétrangère. étude des aspects affectifs , et sur une étude postérieureconcernant les interactions en classe de langue. Des marqueurs non verbauxliés à des paramètres tels que l’implication, l’extraversion, le fait de sesentir à l’aise en classe, la cohésion de groupe et l’adhésion au professeur,sont décrits sur la base de nombreuses heures de classe filmées. Le r lenotamment du regard, du silence, du rire, de l’expression faciale, de certainsgestes, certaines postures est décrit et analysé, parallèlement aux jugementsémis par les apprenants au début et à l’issue du cours.
