Explaining Gender Differences in Caries: A Multifactorial Approach to a Multifactorial Disease
Maria Ferraro,Alexandre R. Vieira
International Journal of Dentistry , 2010, DOI: 10.1155/2010/649643
Abstract: Many studies have demonstrated that caries rates are higher in women than in men. This review attempts to provide an explanation for this trend by examining each factor which contributes to caries and how the factor differs in men and women. Evidence has been provided to demonstrate that caries risk factors for women include a different salivary composition and flow rate, hormonal fluctuations, dietary habits, genetic variations, and particular social roles among their family. Systemic diseases that have been found to be associated with caries have also been found to have an association with the female gender. An extended exposure to the oral cavity or a more cariogenic oral microflora has not been proven to contribute to higher caries in women. Further research in these areas could be done in the future to explain their contribution, or lack thereof, to a higher caries rate in women. 1. Introduction The significant impact of caries on the world’s population makes the disease an important topic of understanding. The development of caries is multifactorial, depending on many interacting variables to promote its development. In particular, the presence of bacteria, a substrate for the bacteria (food/sugars), the host’s oral environment, as well as the passing of time are the main contributing factors in the formation of caries. Epidemiological and clinical studies, through the use of tools such as DMFT and DMFS scores, have revealed a consistent trend in caries development, with females having higher prevalence than males [1]. The mechanisms underlying the reasoning for this trend can possibly be explained by an investigation of the suggested factors involved in caries development. 2. Genetic Contributions: AMELX The underlying mechanisms of any genetic contributions to the increased prevalence of caries in females versus males can be speculated to reside in the sex chromosomes, exhibiting sex-linked modes of inheritance. Genes present on the X or Y chromosome whose function affects those factors which contribute to the development of caries can be investigated. Variations in these genes would alter the host’s oral environment and the host’s response to the initiation of caries. The Amelogenin (AMELX) gene resides on the p arm of the X chromosome. Its locus is Xp22.31-p22.1 [2]. This gene and its protein product contribute to enamel formation in the dentition. The amelogenin protein constitutes 90% of the enamel matrix [3]. A mutation/deletion in the AMELX gene results in X-linked amelogenesis imperfecta [2]. There is a possibility that a deficient

Abstract: Research is currently moving in the direction of an integration between the outcome measures of the patients and the relational and/or structural factors that can facilitate their change. It is increasingly important to focus studies on the relationship between process and outcome, especially with regard to psychodynamic group therapy. These treatments, very complex and difficult to operationalize, still pose critical questions for research such as what are the main elements of the therapeutic process that are activated in these therapies?Many efforts are to be made in understanding which factors develop in groups and the conditions that positively influence the success of therapy. Important is, moreover, the work of conceptual and "operational" depth on the different constructs, to better understand their nature and differences and build tools to more easily detect their features. Therapeutic alliance and cohesion are among the most investigated process variables, because of their role on the results of therapy.This study investigates these two variables in a therapeutic group with severe patients and analyzes their associations with treatment outcomes in term of symptoms and defenses. A long-term, semi-open group meeting on a weekly basis was examined. The observation was carried out for a period of 18 months, for a total amount of 50 sessions; 11 patients with different diagnoses in Axis I and II DSM IV were examined. Outcome measures: SCL-90 - Symptom Check List; OQ-45 - Outcome Questionnaire 45.2; DSQ - Defense Style Questionnaire.Process measures: CALPAS-G: California Psychotherapy Alliance Scale-Group; GMLCS: Group/Member/Leader Cohesion Scale. The observation period was divided into 3 phases according to re-modulations of the setting (new entries, overcomes, dropout). Significant correlations between alliance, cohesion and outcomes were found in the three phases. During the phase of greater instability, the predominant role of cohesion and, more generally, dimensions related to group commitment emerge. Results offer interesting suggestions about the differentiation between Alliance and Cohesion and their different relationship with outcomes and process evolution.
Disidentità: una chiave di lettura per le nuove forme di psicopatologia?

Narrare i Gruppi , 2012,
Abstract: nsformations society has faced in the transition from modernity to postmodernity have shaken the traditional group dimensions, and thereby, personal identity itself. The stray of the sense of belonging, linked to the consideration of some cultural, linguistic, religious traditions as our own, not only prevents from understanding the world. It also hampers the possibility to internalize all those aspects of the experience of "belonging" which, when lost, become nothing more than fragments of an essentially uncertain and provisional world. Taking up some of the concepts of the subjectual group analysis theory of personality, the article proposes a reflection on why some recent anthropological changes may represent a threat in relation to the development of individual identity, with a special focus on the concept of dis-identity. It will therefore highlight the instability of identification dynamics and the connection of this weak spot to the development of new forms of psychopathology.After illustrating the fragility of the internalization process of the composing elements of individual identity, the article associates the partial shadowing of the intersubjective dimension with the emergence of new psychopathological figures.
La gruppoanalisi soggettuale e la terapia di gruppo: introduzione alla teoria e alla prassi
Anna Maria Ferraro,Emanuela Coppola,Girolamo Lo Verso
Narrare i Gruppi , 2012,
Abstract: rticle explains the theoretical foundations of the group-analysis approach, its main Italian developments, and its link with technique. In particular, after showing the hesitations of the original English model, it illustrates the Italian approach (Subjectual Groupanalysis), its evolution and dialogue with disciplines (complexity theory, cultural anthropology) that contributed to the foundation of its meta-psychological apparatus. Subsequently, it focuses on the relational foundation of psyche, on the therapeutic aspects linked to it, highlighting some key aspects of a classic group-analytic functioning, some of the main therapist’s responsibility, and some of the hardest troubles for the patients.
Imagem-objetivo para a descentraliza??o da vigilancia sanitária em nível municipal

Cadernos de Saúde Pública , 2009, DOI: 10.1590/S0102-311X2009001000011
Abstract: no consensus has been reached concerning the definition of criteria and standards for evaluating the decentralization of actions by municipal health surveillance systems. with the aim of developing and validating an objective image for municipal health surveillance that would correspond to an appropriate system for the population's health care needs, a logical framework was elaborated, from which a matrix containing dimensions and criteria for management and practices was obtained. the framework was submitted to an expert group for validation at a consensus conference. of the 54 criteria, there was consensus for 59.3%, while 53 items (98%) were considered important, thus validating the matrix. in view of the provisory nature of the consensuses, the resulting instrument, which can be used either in its entirety or in part, enables modification and adaptation. the authors discuss the potential of the evaluation strategy adopted here, which allows various possibilities for redefining the criteria and renewing the consensus.

Abstract: Male reproductive health in both humans and animals is an important research field in biological study. In order to characterize the morphology, the motility and the concentration of the sperm cells, which are the most important parameters to feature them, digital holography demonstrated to be an attractive technique. Indeed, it is a labelfree, non-invasive and high-resolution method that enables the characterization of live specimen. The review is intended both for summarize the state-of-art on the semen analysis and recent achievement obtained by means of digital holography and for exploring new possible applications of digital holography in this field.
Bilocal Dynamics for Self-Avoiding Walks
Sergio Caracciolo,Maria Serena Causo,Giovanni Ferraro,Mauro Papinutto,Andrea Pelissetto
Physics , 1999, DOI: 10.1023/A:1018719226557
Abstract: We introduce several bilocal algorithms for lattice self-avoiding walks that provide reasonable models for the physical kinetics of polymers in the absence of hydrodynamic effects. We discuss their ergodicity in different confined geometries, for instance in strips and in slabs. A short discussion of the dynamical properties in the absence of interactions is given.

Abstract: Mutations in proteins can have deleterious effects on a protein's stability and function, which ultimately causes particular diseases. Genetically inherited muscular dystrophies (MDs) include several genetic diseases, which cause increasing weakness in muscles and disability to perform muscular functions progressively. Different types of mutations in the gene coding translates into defunct proteins cause different neuro-muscular diseases. Defunct protein interactions in human proteome may cause a stress to its neighboring proteins and its modules. We therefore aimed to understand the effects of mutated proteins on interacting partners in different muscular dystrophies utilizing network biology to understand system properties of these MDs subnetworks .We investigated rigidity and flexibility of protein-protein interaction subnetworks associated with causative mutated genes showing high mean interference values in muscular dystrophy. Rigid component related to EEF1A1 subnetwork and members of 14.3.3 protein family formed the core of network showed involvement in molecular function related to protein domain specific binding. CACNA1S and CALM1 showing functionality related to Voltage-dependent calcium channel demonstrated highest flexibility. The interconnected subnets of proteins corresponding to known causative genes having large genetic variants are shared in different muscular dystrophies inferred towards comorbidity in diseases. The studies demonstrates core network of MDs as highly rigid, constituting of large intermodular edges and interconnected hub nodes suggesting high information transfer flow. The core skeleton of the network is organized in protein specific domain binding. This suggests neuro-muscular disorders may initiate due to interruption in molecular function related with the core and its aggression may depend on the tolerance level of the networks.
