Terapias cognoscitivo comportamentales de tercera generación (terapia de aceptación y compromiso, terapia cognoscitivo comportamental basada en Mindfulness, Psicoterapia Analítica Funcional) para el manejo de la fibromialgia

La fibromialgia es un síndrome doloroso crónico de alta complejidad en su diagnóstico (que hasta la fecha es clínico) y en su manejo. Se caracteriza por la presencia simultánea de numerosos problemas psicológicos en los pacientes, de los cuales se reconoce su asociación con el síndrome pero no la direccionalidad de la asociación. En consecuencia, la atención de las personas que lo desarrollan requiere del despliegue de numerosos esfuerzos interdisciplinarios, con un alto fracaso terapéutico y una mayor cronificación de los síntomas. La Terapia Cognoscitivo Comportamental ha demostrado ser una valiosa herramienta para el abordaje eficaz de las necesidades afectivas, emocionales y comportamentales de esta población. En consecuencia, el presente trabajo de grado tuvo como objetivo realizar una revisión de la literatura hallada en las bases de datos especializadas, sobre la evidencia de las Terapias de Cognoscitivo Comportamentales de Tercera Generación en el manejo de la fibromialgia. Se seleccionaron tres de estas terapias, a saber: la Terapia de Aceptación y Compromiso (TAC), la Terapia Cognoscitiva Basada en Mindfulness (TCBM) y la Psicoterapia Analítica Funcional (PAF). En primer lugar se presenta un breve recorrido histórico de la Terapia Comportamental con el fin de apreciar las diferencias y las similitudes de la Terapia Comportamental en sus tres generaciones. Posteriormente se presenta cada una de las tres terapias seleccionadas, contextualizándolas en cuanto a sus objetivos y evidencia empírica en el campo de la Psicología de la Salud y en específico del dolor crónico y de la fibromialgia. Finalmente, se presentan algunas conclusiones generales y se discute sobre su eficacia y el papel del en estas, en especial para el manejo de la persona con fibromialgia.

THE ROLE OF CULTURAL AWARENESS IN BUILDING CHINESE HEALTH FOOD BRANDS Using Netnography in Searching Cultural Arguments to Be Used for Marketing Health Foods in China

Despite the complexity of the Chinese culture consumer product businesses should apply them in building brands for Chinese markets. There are reasons to believe that cultural values and attitudes affect the buying behavior of Chinese consumers. Companies that wish to create brands in China should therefore be aware of the prevailing cultural values and consumer attitudes. This thesis will examine which values and attitudes mostly affect Chinese consumers of health food products. The study will be done by conducting a netnography. Because netnography is actually a collection methods rather than a single method, other auxiliary methods will also be applied. These methods are emotion, language and sentiment analysis (ELS analysis). Emotion analysis will be conducted because cultural values are mostly built on emotional basis. Sentiment analysis will assist in recognizing the key factors that help to locate values and attitudes. Because the netnography will be conducted in Chinese web forums by a non-native researcher, linguistic aspects should also be analyzed in parallel with emotions and sentiment analysis. The study shows that the Chinese consumers of health food products put much importance on functional, analytical and collectivistic attitudes as well as social and psychological values. Of all the twelve cultural values defined, the role of family rose above all. Also perseverance, frugality, guanxi and harmony were highly presented. The attitudes were found by recognizing certain attitude factors. Of all the factors, health foods’ functional benefits and aesthetic content together with consumers’ value consciousness surpassed other factors. Besides these results that can be applied by foreign health food companies willing to enter Chinese consumer markets, also academia can benefit this new approach for conducting ethnographies online.

Künstliche Randbedingungen und Algebraische Äquivalenzen in der Elastizitätstheorie

In dieser Arbeit werden zwei Aspekte bei Randwertproblemen der linearen Elastizitätstheorie untersucht: die Approximation von Lösungen auf unbeschränkten Gebieten und die Änderung von Symmetrieklassen unter speziellen Transformationen. Ausgangspunkt der Dissertation ist das von Specovius-Neugebauer und Nazarov in "Artificial boundary conditions for Petrovsky systems of second order in exterior domains and in other domains of conical type"(Math. Meth. Appl. Sci, 2004; 27) eingeführte Verfahren zur Untersuchung von Petrovsky-Systemen zweiter Ordnung in Außenraumgebieten und Gebieten mit konischen Ausgängen mit Hilfe der Methode der künstlichen Randbedingungen. Dabei werden für die Ermittlung von Lösungen der Randwertprobleme die unbeschränkten Gebiete durch das Abschneiden mit einer Kugel beschränkt, und es wird eine künstliche Randbedingung konstruiert, um die Lösung des Problems möglichst gut zu approximieren. Das Verfahren wird dahingehend verändert, dass das abschneidende Gebiet ein Polyeder ist, da es für die Lösung des Approximationsproblems mit üblichen Finite-Element-Diskretisierungen von Vorteil sei, wenn das zu triangulierende Gebiet einen polygonalen Rand besitzt. Zu Beginn der Arbeit werden die wichtigsten funktionalanalytischen Begriffe und Ergebnisse der Theorie elliptischer Differentialoperatoren vorgestellt. Danach folgt der Hauptteil der Arbeit, der sich in drei Bereiche untergliedert. Als erstes wird für abschneidende Polyedergebiete eine formale Konstruktion der künstlichen Randbedingungen angegeben. Danach folgt der Nachweis der Existenz und Eindeutigkeit der Lösung des approximativen Randwertproblems auf dem abgeschnittenen Gebiet und im Anschluss wird eine Abschätzung für den resultierenden Abschneidefehler geliefert. An die theoretischen Ausführungen schließt sich die Betrachtung von Anwendungsbereiche an. Hier werden ebene Rissprobleme und Polarisationsmatrizen dreidimensionaler Außenraumprobleme der Elastizitätstheorie erläutert. Der letzte Abschnitt behandelt den zweiten Aspekt der Arbeit, den Bereich der Algebraischen Äquivalenzen. Hier geht es um die Transformation von Symmetrieklassen, um die Kenntnis der Fundamentallösung der Elastizitätsprobleme für transversalisotrope Medien auch für Medien zu nutzen, die nicht von transversalisotroper Struktur sind. Eine allgemeine Darstellung aller Klassen konnte hier nicht geliefert werden. Als Beispiel für das Vorgehen wird eine Klasse von orthotropen Medien im dreidimensionalen Fall angegeben, die sich auf den Fall der Transversalisotropie reduzieren lässt.

Genericity of Nondegeneracy for Light Rays in Stationary Spacetimes

Given a Lorentzian manifold (M, g), an event p and an observer U in M, then p and U are light conjugate if there exists a lightlike geodesic gamma : [0, 1] -> M joining p and U whose endpoints are conjugate along gamma. Using functional analytical techniques, we prove that if one fixes p and U in a differentiable manifold M, then the set of stationary Lorentzian metrics in M for which p and U are not light conjugate is generic in a strong sense. The result is obtained by reduction to a Finsler geodesic problem via a second order Fermat principle for light rays, and using a transversality argument in an infinite dimensional Banach manifold setup.

Convention, Tradition, and the New Wave : Assessing Clinician Identity within Behavior Therapy

In the first wave, behaviorists questioned the conventional wisdom that inner experience was relevant to understanding human behavior. In the 1970s, cognitive-behavioral theories emphasized the importance of the cognitive element, not just the environment, in explaining and modifying behavior. The third wave is drawn from advances in basic and applied behavior analysis of language, Eastern mystical traditions, and less empirically oriented therapeutic approaches. Examples include Acceptance and Commitment Therapy (ACT), Dialectical Behavior Therapy (DBT), Functional Analytic Psychotherapy (FAP), and Mindfulness Based Cognitive Therapy (IBCT). This study reports a survey of clinicians and non-clinicians who self-identify with second or third wave approaches, and a group of undergraduate psychology students intended to represent a layperson or folk psychological approach. Their preferences, in the context of 10 clinical vignettes, among 5 different therapeutic responses or interventions that included "ACT-like," "cognitive," and commonsense or "neutral" options were measured. Third wave-oriented respondents exhibited more consistency than others in their preference for interventions that match their self-identified theoretical orientation, however the author suggests that construction of the vignettes may have influenced this result.

Analytical strategies for the comprehensive profiling of histone post translational modifications by mass spectrometry and implications for functional analyses

Le long bio-polymère d'ADN est condensé à l’intérieur du noyau des cellules eukaryotes à l'aide de petites protéines appelées histones. En plus de leurs fonctions condensatrices,ces histones sont également la cible de nombreuses modifications post-traductionnelles(MPT), particulièrement au niveau de leur section N-terminale. Ces modifications réversibles font partie d’un code d’histones épi-génétique transmissible qui orchestre et module dynamiquement certains événements impliquant la chromatine, tels l’activation et la désactivation de gènes ainsi que la duplication et la réparation d’ADN. Ces modifications sont impliquées subséquemment dans la signalisation et la progression de cancers, tels que la leucémie. En conséquence, l'élucidation des modifications d’histones est importante pour comprendre leurs fonctions biologiques. Une méthodologie analytique a été mise au point en laboratoire pour isoler, détecter, et quantifier les MPT d’histones en utilisant une approche rapide à deux volets à l’aide d’outils bioinformatiques spécialisés. La méthodologie développée en laboratoire a été validée en utilisant des histones de souche sauvage ainsi que deux types d’histones mutants déficients en enzymes acétyltransferase. Des trois sources d’histones utilisées, la seule MPT qui a démontré un changement significatif est l’acétylation de l’histone H3 à lysine 56 (H3K56ac). L’expression et la stoechiométrie de cette MPT, issue de cellules de souche sauvage et de cellules mutantes, ont été déterminées avec précision et comparées. Les fonctions de balayage polyvalentes d'un instrument à trappe ionique quadrupôle linéaire hybride ont été utilisées pour améliorer la détection de protéines intactes. Le mode de balayage « enhanced multiply charged » (EMC) a été modifié pour contenir et détecter les ions de protéines intactes situées dans la trappe ionique linéaire. Ce mode de balayage nommé « targeted EMC » (tEMC) a permis de quadrupler le niveau de sensibilité (signal/interférence), et quintupler la résolution du mode de balayage conventionnel. De plus, la capacité de séparation des charges du tEMC a réduit de façon significative les effets de « space charge » dans la trappe ionique linéaire. La résolution supérieure du mode tEMC a permis de différencier plusieurs isoformes modifiées, particulièrement pour l’histone H3. L’analyse des peptides d’histones trypsiques à l’aide du mode de balayage « MRM » a permis le séquençage et la quantification de MPT avec un haut degré de précision. La seule MPT qui était sous-exprimée entre l’histone de souche sauvage et le mutant DOT1L fut la méthylation de l’histone H3 lysine 79(H3K79me1). Les effets de deux inhibiteurs d’enzymes HDAC (HDACi) sur l’expression de MPT d’histone ont été évalués en utilisant la méthodologie analytique mentionnée. Les histones extraites de cellules normales et cancéreuses ont été exposées à du Vorinostat(SAHA) ou du Entinostat (MS-275) pour une période de 24 à 72 heures. Deux histones furent principalement affectées, soit H3 et H4. Étonnamment, les mêmes effets n'ont pas été détectés lorsque les cellules normales ont été traitées avec le HDACi pour une période de 48 à 72 heures. Une méthode absolue de quantification avec une courbe d’étalonnage a été développée pour le peptide H3K56ac. Contrairement à certaines publications, nos résultats démontrent que cette MPT est présente dans les cellules mammifères avec une stoechiométrie très basse (< 0,1%) et n'est pas surexprimée de façon significative après le traitement au HDACi.

Traumatic memories: bridging the gap between functional neuroimaging and psychotherapy

Objective: Neuroimaging studies have highlighted important issues related to structural and functional brain changes found in sufferers of psychological trauma that may influence their ability to synthesize, categorize, and integrate traumatic memories. Methods: Literature review and critical analysis and synthesis. Results: Traumatic memories are diagnostic symptoms of post-traumatic stress disorder (PTSD), and the dual representation theory posits separate memory systems subserving vivid re-experiencing (non-hippocampally dependent) versus declarative autobiographical memories of trauma (hippocampally dependent). But the psychopathological signs of trauma are not static over time, nor is the expression of traumatic memories. Multiple memory systems are activated simultaneously and in parallel on various occasions. Neural circuitry interaction is a crucial aspect in the development of a psychotherapeutic approach that may favour an integrative translation of the sensory fragments of the traumatic memory into a declarative memory system. Conclusion: The relationship between neuroimaging findings and psychological approaches is discussed for greater efficacy in the treatment of psychologically traumatized patients.

Functional components and lipid quality assessment in vegetable foods: analytical and technological approaches

Lipids are important components that contribute very significantly to nutritional and technological quality of foods because they are the least stable macro-components in foods, due to high susceptibility to oxidation. When rancidity take place, it makes food unhealthy and unacceptable for consumers. Thus, the presence of antioxidants, naturally present of added to foods, is required to enhance shelf life of foods. Moreover, antioxidant like phenolic compounds play an important role in human health enhancing the functionality of foods. The aim of this PhD project was the study of lipid quality and lipid oxidation in different vegetable foods focusing on analytical and technological aspects in order to figure out the effects of lipid composition and bioactive compounds (phenolic compounds, omega-3 fatty acids and dietary fiber) addition on their shelf life. In addition, bioavailability and antioxidant effects of phenolic compounds in human and animals, respectively, were evaluated after consumption of vegetable foods. The first section of the work was focused on the evaluation of lipid quality impact on technological behaviour of vegetable foods. Because of that, cocoa butter with different melting point were evaluated by chromatographic techniques (GC, TLC) and the sample with the higher melting point showed the presence of fatty acids, triglycerides, 2-monoglycerides and FT-IR profile different from genuine cocoa butter, meaning an adding of foreign fat (lauric-fat) not allowed by the law. Looking at lipid quality of other vegetable foods, an accelerated shelf life test (OXITEST®), was used to evaluate of lipid stability to oxidation in tarallini snacks made up using different lipid matrices (sunflower oil, extravirgin olive oil and a blend of extravirgin olive oil and lard). The results showed a good ability of OXITEST® to discriminate between lipid unsaturation and different cooking times, without any samples fat extraction. In the second section, the role of bioactive compounds on cereal based food shelf life was studied in different bakeries by GC, spectrophotometric methods and capillary electrophoresis. It was examined the relationships between phenolic compounds, added with flour, and lipid oxidation of tarallini and frollini. Both products showed an increase in lipid oxidation during storage and antioxidant effects on lipid oxidation were not as expected. Furthermore, the influence of enrichment in polyunsaturated fatty acids on lipid oxidation of pasta was evaluated. The results proved that LC n-3 PUFA were not significantly implicated in the onset of oxidation in spaghetti stored under daylight and accelerated oxidation in a laboratory heater. The importance of phenolic compounds as antioxidant in humans and rats was also studied, by HPLC/MS in the latter section. For this purpose, apigenin and apigenin glycosides excretion was investigated in six women’s urine in a 24 hours study. After a single dose of steamed artichokes, both aglicone and glucuronide metabolites were recovered in 24 h urine. Moreover, the effect of whole grain durum wheat bread and whole grain Kamut® khorasan bread in rats were evaluated. Both cereals were good sources of antioxidants but Kamut® bread fed animals had a better response to stress than wheat durum fed, especially when a sourdough bread was supplied.

A first-principles density-functional calculation of the electronic and vibrational structure of the key melanin monomers

We report first-principles density-functional calculations for hydroquinone (HQ), indolequinone (IQ), and semiquinone (SQ). These molecules are believed to be the basic building blocks of the eumelanins, a class of biomacromolecules with important biological functions (including photoprotection) and with the potential for certain bioengineering applications. We have used the difference of self-consistent fields method to study the energy gap between the highest occupied molecular orbital and the lowest unoccupied molecular orbital, HL. We show that HL is similar in IQ and SQ, but approximately twice as large in HQ. This may have important implications for our understanding of the observed broadband optical absorption of the eumelanins. The possibility of using this difference in HL to molecularly engineer the electronic properties of eumelanins is discussed. We calculate the infrared and Raman spectra of the three redox forms from first principles. Each of the molecules have significantly different infrared and Raman signatures, and so these spectra could be used in situ to nondestructively identify the monomeric content of macromolecules. It is hoped that this may be a helpful analytical tool in determining the structure of eumelanin macromolecules and hence in helping to determine the structure-property-function relationships that control the behavior of the eumelanins.

A semi-analytical solution for vibration of rectangular plates with abrupt thickness variation

A semi-analytical analysis of free vibration of plates with cross-sectional discontinuities due to abrupt changes in thickness is presented. A basic square element divided into suitable subdomains dependent upon the positions of these abrupt changes is used as the basic building element, Admissible functions that satisfy the essential or geometric boundary conditions are used to define the transverse deflection of each subdomain. Continuities in the displacement, slope, moment and higher derivatives between adjacent subdomains are enforced at the interconnecting edges. The resulting global energy functional from the proper assembly of the coupled strain and kinetic energy contributions of each subdomain is then minimized via the Ritz procedure to extract the frequencies and mode shapes. Contour plots of a range of new mode shapes are presented for the enhancement of understanding the dynamic behavior of this class of plates, (C) 2001 Elsevier Science Ltd, All rights reserved.
