Incidence of type 1 diabetes mellitus in Passo Fundo, RS, Brazil

To establish the incidence of type 1 diabetes among children (infants to 14 years of age) in the city of Passo Fundo, Rio Grande do Sul, Brazil (population under 15 years = 50,098), during the period of January to December 1996, a retrospective and prospective population-based registry was established, using physician reports of newly diagnosed patients under 15 years of age with type 1 diabetes as the primary source of case identification. Primary and nursery schools and a general call through the media (newspapers, radio and television) was the secondary source. Data were calculated according to the methods recommended by the WHO (1990). Six new cases were identified. Case ascertainment was estimated at 100%. The incidence of type 1 diabetes in the year 1996 was 12/100,000 inhabitants. These data indicate that the incidence of childhood type 1 diabetes in a subtropical region in the Southern part of Brazil was similar to that observed in developed countries throughout the world. The inability to demonstrate the North-South gradient is probably due to the European origin of inhabitants of the city.

Somatic cytogenetic and azoospermia factor gene microdeletion studies in infertile men

The objective of the present study was to determine the frequency of somatic chromosomal anomalies and Y chromosomal microdeletions (azoospermia factor genes, AZF) in infertile males who seek assisted reproduction. These studies are very important because the assisted reproduction techniques (mainly intracytoplasmic sperm injection) bypass the natural selection process and some classical chromosomal abnormalities, microdeletions of AZF genes or some deleterious genic mutations could pass through generations. These genetic abnormalities can cause in the offspring of these patients male infertility, ambiguous external genitalia, mental retardation, and other birth defects. We studied 165 infertile men whose infertility was attributable to testicular problems (60 were azoospermic, 100 were oligospermic and 5 were asthenospermic). We studied 100 metaphases per patient with GTG banding obtained from temporary lymphocyte culture for chromosomal abnormality detection and performed a genomic DNA analysis using 28 Y chromosome-specific sequence-tagged sites for Y AZF microdeletion detection. Karyotyping revealed somatic anomalies in 16 subjects (16/165 = 9.6%). Of these 16, 12 were in the azoospermic group (12/60 = 20%) and 4 were in the oligospermic group (4/100 = 4%). The most common chromosomal anomaly was Klinefelter syndrome (10/165 = 6%). Microdeletions of AZF genes were detected in 12 subjects (12/160 = 7.5%). The frequencies detected are similar to those described previously. These results show the importance of genetic evaluation of infertile males prior to assisted reproduction. Such evaluation can lead to genetic counseling and, consequently, to primary and secondary prevention of mental retardation and birth defects.

Bilateral repetitive transcranial magnetic stimulation for treatment-resistant depression: a systematic review and meta-analysis of randomized controlled trials

There has been concern regarding the use of controversial paradigms for repetitive transcranial magnetic stimulation (rTMS) to manage treatment-resistant depression (TRD). This meta-analysis assessed the efficacy of bilateral rTMS compared with unilateral and sham rTMS in patients with TRD. PubMed, Embase, CENTRAL, PsycINFO, Web of Science, EAGLE and NTIS databases were searched to identify relevant studies, and randomized controlled trials (RCTs) on bilateral rTMS for TRD patients were included. The response was defined as the primary outcome, and remission was the secondary outcome. Ten RCTs that included 634 patients met the eligibility criteria. The risk ratio (RRs) of both the primary and secondary outcomes of bilateral rTMS showed non-significant increases compared to unilateral rTMS (RR=1.01, P=0.93; odds ratio [OR]=0.77, P=0.22). Notably, the RR of the primary bilateral rTMS outcome was significantly increased compared to that for sham rTMS (RR=3.43, P=0.0004). The results of our analysis demonstrated that bilateral rTMS was significantly more effective than sham rTMS but not unilateral rTMS in patients with TRD. Thus, bilateral rTMS may not be a useful paradigm for patients with TRD.

The role of network competence and international business competence in multinational corporations: Subsidiary perspective

On-going process of globalization makes companies all over the world to go beyond the national markets and internationalize. Organizational form of multinational corporation (MNC) has capabilities for establishing the affiliate companies in several countries. Thus, the relocation of resources occurs and particularly, the cross-border transfer of knowledge which possesses the competitive advantage. However, differences in countries` business environments and cultures may constrain this capability. The research aim of this thesis is to investigate the role of subsidiary’s network competence (ability to build and manage the relationships with other local business units) and international business competence in relation to the benefits that MNC receives from a subsidiary. Additionally, subsidiary’s business adaptation, partnerships and knowledge transfer mechanism with parent company and external partners are investigated. This research, conducted in the Finnish-Russian context, consists of theoretical and empirical parts. The qualitative approach in the form of multiple case studies is employed. The empirical data incorporated primary and secondary data in the form of interviews collected in 2013 and 2015 years. Interviews were collected from four Finnish case companies in Saint-Petersburg and Kaluga region and five Russian partner companies. Results are drawn from two cases from Saint-Petersburg. The abductive research approach for the results analysis is adopted. The results indicate that both competencies lead to the subsidiary’s local embeddedness in the form of mutual business activities with local business partners and product adaptation for the local market needs. In addition to the monetary benefits in form of payments or turnover share, local embeddedness brings the knowledge of the local environment which is utilized by an MNC in the long-term planning. Another found tacit benefit is the access to the national market. This is strategically useful benefit not only for parent MNC but also for the subsidiary’s partners, i.e. international suppliers.

Khrushchev's Beau Geste: the Return of Porkkala and its Global Significance

The return of the Porkkala naval base, which was leased to the Soviet Union at the end of World War II was unexpectedly returned in early 1956, 42 years before the USSR's lease on the area was to expire. There is no commonly accepted reason, and therefore the purpose of this work is to study the possible motives behind the return of Porkkala. These seem to have been reflected in the new foreign policy after the death of Stalin, which went far beyond returning Porkkala to Finland. The Soviet Union's courting of the non-aligned powers during this time, into which category Finland was assigned, also seems to be more than coincidence. However, the greater events of 1956, and the fact that Porkkala is remembered almost exclusively in Finland may have conspired to trap the events around Porkkala into the smaller narrative of Finnish-Soviet relations and the rise of Kekkonen to the presidency, due in no small part to his presence in negotiating the return of Porkkala. However this does not negate the message that Porkkala was intended to broadcast the USSR's new approach to neutrality. Through primary and secondary sources, gleaned from archives in Finland, memoirs of people involved, and historical literature, this thesis hopes to broaden the view that Porkkala's main and only significance lay in the changes it brought to Finnish-Soviet relations.

Learning and healing: a wellness pedagogy for Aboriginal teacher education /

During the last 30 years Aboriginal peoples in Canada have made steady progress in reclaiming the responsibility for the education of their young people, especially in primary and secondary school. In comparison the education and or training of adult populations has not kept pace and many socioeconomic and sociocultural indicators demonstrate a ' , continued confinement of those populations to the margins of the dominant society of Canada. It is the adults, the mothers and the fathers, the grandmothers and grandfathers, the aunties and uncles that are the first teachers of the next generation and the nature of these relationships replicates the culture of unwellness in each subsequent generation through those teachers. There are few examples in the Aboriginal adult education literatures that give voice to the educational experience of the Learner. This study addresses that gap by exploring the perspectives embedded in the stories of a Circle of Learners who are, or were enrolled in the Bachelor of Education in Aboriginal Adult Education program at Brock University. That Circle of 1 participants included 9 women and 1 man, 6 of whom were from various i Anishinabek nations while 4 represented the Hotinonshd:ni nations in southern Ontario. They are an eclectic group, representing many professions, age groups, spiritual traditions, and backgrounds. This then is their story, the story of the heaming and Healing pedagogy and an expanded vision of Aboriginal education and research at Brock University.

Relating leadership, thinking styles, self-concept, motivation and stress management in education

Seventy-five principals and vice-.wincipals from public elementary and secondary schools in Hamilton, Ontario, Canada participated in this study. Participants provided ,information concerning their thinking styles, motivations, and the physical effects of stress. This information was examined to find out how satisfaction-oriented, and how security-oriented the thinking styles of the participants were. Second, the data were analysed to see how the thinking style orientations related to life style habits and the effects of stress. The satisfaction-oriented thinking styles scored higher than all of the security-oriented thinking styles by a wide margin with a small preference for the satisfaction-people-oriented styles labelled humanistic-helpful, and affiliative as opposed to the satisfaction-task-oriented styles labeled achievement, and self-actualizing. Although all eight of the security-oriented thinking styles scored well below all of the satisfaction-oriented thinking styles on the Life Styles Inventory, the perfectionistic style scored higher than all of the security-oriented styles by an impressive margin. The next highest scores were recorded by a cluster of three passive-defensive people-oriented thinking styles labeled approval, conventional, and dependent. The competitive style scored lower, and the styles labeled avoidance, oppositional, and power scored the lowest of all the defensive-security-oriented styles. These findings suggest that principals and vice-principals see themselves as relaxed, flexible, and satisfied with their ability to adapt to the stress levels they experience in their lives; however, there was some support for medical research findings that suggest that specific security-oriented thinking styles are associated with emotional stresses that contribute to the development of specific lifestyle habits, physical symptoms, and illnesses. Although the number of females in this study provides very limited generalizability, the findings of this study suggest that high achieving females tend to develop satisfaction-growth styles to a higher level than males, and they tend to use security-oriented styles to a lesser degree than males.

Teachers' likes and dislikes as factors in educational change

Teachers at local elementary and secondary schools were invited to participate in a survey research study by completing a questionnaire containing 26 statements regarding educational issues (e.g., "I am satisfied with the quality of my interactions with students."). Teachers were asked to indicate whether they agreed, were neutral, or disagreed with each statement; and further, to make a suggestions for appropriate change; to indicate a level at which the change could be implemented (classroom, school, board, ministry, society); and to indicate to what extent they perceive they have influence on change in the area represented in the statement. The responses of 50 elementary and 50 secondary teachers were randomly chosen from among the completed questionnaires and the information was recorded for analysis. Results of frequency counts of responses showed teachers were generally satisfied with their experiences of the areas referred to in the statements. Seventy-two percent of the responses agreed with the statements; 15% of the responses indicated disagreement, and 13% of the responses were neutral. Cross-tabulations of the survey data with demographic information showed differences among the responses of female and male teachers; elementary and secondary teachers; and teachers grouped according to their total years of teaching experience.

Biotransformation of aromatic hydrocarbons and organic sulphides by fungi

Toluene is converted to benzyl alcohol by the fungi Mortierella isabellina and Helminthosporium species; in the latter case, the product is further metabolized. Toluene-a -d 1 , toluene-a,a-d2, and toluene-a,a,a-d 3 have been used with Mortierellaisabellina in a series of experiments to determine both primary and secondary deuterium kinetic isotope effects for the enzymic benzylic hydroxylation reaction. The values obtained, intermolecular primary kH/kD = intramolecular p rim a r y kH r kD = 1. 0 2 + O. 0 5, and sec 0 n dar y k H I kD = 1. 37 .:!. 0.05, suggest a mechanism for the reaction involving benzylic proton removal from a radical intermediate in a non-symmetrical transition state. 2H NMR (30.7 MHz) studies using ethylbenzene-l,1-d 2 , 3 -fluoroethylbenzene-l,1-d 2 , 4 -fluoroethylbenzene-l,1-d 2 , and toluene-dB as substrates with Mortierella isabellina suggest, based on the observable differences in rates of conversion between the substrates, that the hydroxylation of hydrocarbons at the benzylic position proceeds via a one electron abstraction from the aromatic ring, giving a radical cation. A series of 1,3-oxathiolanes (eight) were incubated with Mortierella isabellina , Helminthosporium , Rhizopus arrhizus , and Aspergillus niger . Sulphoxides were obtained from Mortierella isabellina and Rhizopus arrhizus using the substrates 2-phenyl-, 2-methyl-2-phenyl-, and 2-phenyl-2-tert. butyl-l,3-oxathiolane. The relative stereochemistry of 2-methyl-2-phenyl-l,3-oxathiolan-l-oxide was assigned based on lH decoupling, n.O.e, 1 and H NMR experiments. The lH NMR (200 MHz) of the methylene protons of 2-methyl-2-phenyl-l,3-oxathiolan-l-oxide was used as a diagnostic standard in assigning the relative stereochemistry of 2-phenyl-l,3-oxathiolan-l-oxide and 2-phenyl-2-tert. butyl-l,3-oxathiolan-l-oxide. The sulphoxides obtained were consistent with an oxidation occurring from the opposite side of the molecule to the phenyl substituent.

Physical volcanology, sedimentology, stratigraphy and petrochemistry of the Berry Creek metavolcanics: an Archean calc-alkaline complex, Lake of the Woods, Ontario

The steeply dipping, isoclinally folded early Precambrian (Archean) Berry Creek Metavolcanic Complex comprises primary to resedimented pyroclastic, epiclastic and autoclastic deposits. Tephra erupted from central volcanic edifices was dumped by mass flow mechanisms into peripheral volcanosedimentary depressions. Sedimentation has been essentially contemporaneous with eruption and transport of tephra. The monolithic to heterolithic tuffaceous horizons are interpreted as subaerial to subaqueous pumice and ash flows, secondary debris flows, lahars, slump deposits and turbidites. Monolithic debris flows, derived from crumble breccia and dcme talus, formed during downslope collapse and subsequent gravity flowage. Heterolithic tuff, lahars and lava flow morphologies suggest at least temporary emergence of the edifice. Local collapse may have accompanied pyroclastic volcanism. The tephra, produced by hydromagmatic to magmatic eruptions, were rapidly transported, by primary and secondary mechanisms, to a shallow littoral to deep water subaqueous fan developed upon the subjacent mafic metavolcanic platform. Deposition resulted from traction, traction carpet, and suspension sedimentation from laminar to turbulent flows. Facies mapping revealed proximal (channel to overbank) to distal facies epiclastics (greywackes, argillite) intercalated with proximal vent to medial fan facies crystal rich ash flows, debris flows, bedded tuff and shallow water to deep water lava flows. Framework and matrix support debris flows exhibit a variety of subaqueous sedimentary structures, e.g., coarse tail grading, double grading, inverse to normal grading, graded stratified pebbly horizons, erosional channels. Pelitic to psammitic AE turbidites also contain primary stru~tures, e.g., flames, load casts, dewatering pipes. Despite low to intermediate pressure greenschist to amphibolite grade metamorphism and variably penetrative deformation, relicts of pumice fragments and shards were recognized as recrystallized quartzofeldspathic pseudomorphs. The mafic to felsic metavolcanics and metasediments contain blasts of hornblende, actinolite, garnet, pistacitic epidote, staurolite, albitic plagioclase, and rarely andalusite and cordierite. The mafic metavolcanics (Adams River Bay, Black River, Kenu Lake, Lobstick Bay, Snake Bay) display _holeiitic trends with komatiitic affinities. Chemical variations are consistent with high level fractionation of olivine, plagioclase, amphibole, and later magnetite from a parental komatiite. The intermediate to felsic (64-74% Si02) metavolcanics generally exhibit calc-alkaline trends. The compositional discontinuity, defined by major and trace element diversity, can be explained by a mechanism involving two different magma sources. Application of fractionation series models are inconsistent with the observed data. The tholeiitic basalts and basaltic andesites are probably derived by low pressure fractionation of a depleted (high degree of partial melting) mantle source. The depleted (low Y, Zr) calc-alkaline metavolcanics may be produced by partial melting of a geochemically evolved source, e.g., tonalitetrondhjemite, garnet amphibolite or hydrous basalt.

A Study of Nonfans and Fans of the National Lacrosse League's Edmonton Rush

The National Lacrosse League (NLL) is floundering. In an attempt to understand why NLL fans attend games and other sport fans do not, the NLL’s Edmonton Rush were studied. To best address the NLL’s attendance woes, two primary research questions were developed: 1) Why do fans of the Oilers and Oil Kings choose not to attend Edmonton Rush games? 2) Why do fans of the Edmonton Rush attend games? To answer these questions an online focus group along with a document analysis of Rush media, and a telephone interview were used to collect data. The data collection methods mentioned above assisted in answering the primary and secondary research questions, which allowed three major themes along with sub-themes to inductively emerge. The nonfans of the Rush do not attend Rush games because of the connection they have with hockey and the disconnection they have with lacrosse, some are simply not interested or were not entertained, as well as the lack of exposure the Rush receive. The Rush fan participants attend Rush games because of Edmonton community pride, the entertainment value they get out of attending a game, it is a great alternative new sport experience and it either is a substitute or a compliment to hockey. Both the nonfan and fan participants of this study believe that different marketing approaches can be utilized in order to attract nonfans to attend games.

Intra- and inter-hemispheric interactions in somatosensory processing of pain : dynamical causal modeling analysis of fMRI data

La douleur est une expérience perceptive comportant de nombreuses dimensions. Ces dimensions de douleur sont inter-reliées et recrutent des réseaux neuronaux qui traitent les informations correspondantes. L’élucidation de l'architecture fonctionnelle qui supporte les différents aspects perceptifs de l'expérience est donc une étape fondamentale pour notre compréhension du rôle fonctionnel des différentes régions de la matrice cérébrale de la douleur dans les circuits corticaux qui sous tendent l'expérience subjective de la douleur. Parmi les diverses régions du cerveau impliquées dans le traitement de l'information nociceptive, le cortex somatosensoriel primaire et secondaire (S1 et S2) sont les principales régions généralement associées au traitement de l'aspect sensori-discriminatif de la douleur. Toutefois, l'organisation fonctionnelle dans ces régions somato-sensorielles n’est pas complètement claire et relativement peu d'études ont examiné directement l'intégration de l'information entre les régions somatiques sensorielles. Ainsi, plusieurs questions demeurent concernant la relation hiérarchique entre S1 et S2, ainsi que le rôle fonctionnel des connexions inter-hémisphériques des régions somatiques sensorielles homologues. De même, le traitement en série ou en parallèle au sein du système somatosensoriel constitue un autre élément de questionnement qui nécessite un examen plus approfondi. Le but de la présente étude était de tester un certain nombre d'hypothèses sur la causalité dans les interactions fonctionnelle entre S1 et S2, alors que les sujets recevaient des chocs électriques douloureux. Nous avons mis en place une méthode de modélisation de la connectivité, qui utilise une description de causalité de la dynamique du système, afin d'étudier les interactions entre les sites d'activation définie par un ensemble de données provenant d'une étude d'imagerie fonctionnelle. Notre paradigme est constitué de 3 session expérimentales en utilisant des chocs électriques à trois différents niveaux d’intensité, soit modérément douloureux (niveau 3), soit légèrement douloureux (niveau 2), soit complètement non douloureux (niveau 1). Par conséquent, notre paradigme nous a permis d'étudier comment l'intensité du stimulus est codé dans notre réseau d'intérêt, et comment la connectivité des différentes régions est modulée dans les conditions de stimulation différentes. Nos résultats sont en faveur du mode sériel de traitement de l’information somatosensorielle nociceptive avec un apport prédominant de la voie thalamocorticale vers S1 controlatérale au site de stimulation. Nos résultats impliquent que l'information se propage de S1 controlatéral à travers notre réseau d'intérêt composé des cortex S1 bilatéraux et S2. Notre analyse indique que la connexion S1→S2 est renforcée par la douleur, ce qui suggère que S2 est plus élevé dans la hiérarchie du traitement de la douleur que S1, conformément aux conclusions précédentes neurophysiologiques et de magnétoencéphalographie. Enfin, notre analyse fournit des preuves de l'entrée de l'information somatosensorielle dans l'hémisphère controlatéral au côté de stimulation, avec des connexions inter-hémisphériques responsable du transfert de l'information à l'hémisphère ipsilatéral.

The roles of the somatosensory cortices in the perception of noxious and innocuous stimuli

Résumé Les premières études électrophysiologiques et anatomiques ont établi le rôle crucial du cortex somatosensoriel primaire et secondaire (SI et SII) dans le traitement de l'information somatosensorielle. Toutefois, les récentes avancées en techniques d’imagerie cérébrale ont mis en question leur rôle dans la perception somatosensorielle. La réorganisation du cortex somatosensoriel est un phénomène qui a été proposé comme cause de la douleur du membre fantôme chez les individus amputés. Comme la plupart des études se sont concentrées sur le rôle du SI, une étude plus approfondie est nécessaire. La présente série d'expériences implique une exploration du rôle des régions somatosensorielles dans la perception des stimuli douleureux et non-douleureux chez des volontaires sains et patients avec des douleurs de membre fantôme. La première étude expérimentale présentée dans le chapitre 3 est une méta-analyse des études de neuro-imagerie employant des stimuli nociceptifs chez des volontaires sains. En comparaison aux précédentes, la présente étude permet la génération de cartes quantitatives probabilistes permettant la localisation des régions activées en réponse à des stimuli nociceptifs. Le rôle du cortex somatosensoriel dans la perception consciente de stimuli chauds a été étudié dans le chapitre 4 grâce à une étude d'imagerie par résonance magnétique fonctionnelle, dans laquelle des stimuli thermiques douloureux et non-douloureux ont été administrés de manière contrebalancée. Grâce à cette procédure, la perception de la chaleur fut atténuée par les stimuli douloureux, ce qui permit la comparaison des stimuli consciemment perçus avec ceux qui ne le furent pas. Les résultats ont montrés que les stimulations chaudes perçues ont engendré l’activation de l’aire SI controlatérale, ainsi que de la région SII. Grâce à l’évaluation clinique de patients amputés présentant une altération de leurs perceptions somatosensorielles, il est également possible de dessiner un aperçu des régions corticales qui sous-tendent ces modifications perceptuelles. Dans le chapitre 5 nous avons émis l'hypothèse proposant que les sensations du membre fantôme représentent un corrélat perceptuel de la réorganisation somatotopique des représentations sensorielles corticales. En effet, la réorganisation des sensations peut donner des indices sur les régions impliquées dans la genèse des sensations référées. Ainsi, un protocole d’évaluation sensoriel a été administré à un groupe de patients affligés de douleur au niveau du membre fantôme. Les résultats ont montré que, contrairement aux études précédentes, les sensations diffèrent grandement selon le type et l'intensité des stimuli tactiles, sans évidence de la présence d’un modèle spatialement localisé. Toutefois, les résultats actuels suggèrent que les régions corticales à champs récepteurs bilatéraux présentent également des modifications en réponse à une déafférentation. Ces études présentent une nouvelle image des régions corticales impliquées dans la perception des stimuli somatosensoriels, lesquelles comprennent les aires SI et SII, ainsi que l'insula. Les résultats sont pertinents à notre compréhension des corrélats neurologiques de la perception somatosensorielle consciente.

The role of PPARgamma in cartilage growth and development using cartilage-specific PPARgamma knockout mice

Le cartilage est un tissu conjonctif composé d’une seule sorte de cellule nommée chondrocytes. Ce tissu offre une fondation pour la formation des os. Les os longs se développent par l'ossification endochondral. Ce processus implique la coordination entre la prolifération, la différenciation et l'apoptose des chondrocytes, et résulte au remplacement du cartilage par l'os. Des anomalies au niveau du squelette et des défauts liés à l’âge tels que l’arthrose (OA) apparaissent lorsqu’il y a une perturbation dans l’équilibre du processus de développement. À ce jour, les mécanismes exacts contrôlant la fonction et le comportement des chondrocytes pendant la croissance et le développement du cartilage sont inconnus. Le récepteur activateur de la prolifération des peroxysomes (PPAR) gamma est un facteur de transcription impliqué dans l'homéostasie des lipides. Plus récemment, son implication a aussi été suggérée dans l'homéostasie osseuse. Cependant, le rôle de PPARγ in vivo dans la croissance et le développement du cartilage est inconnu. Donc, pour la première fois, cette étude examine le rôle spécifique de PPARγ in vivo dans la croissance et le développement du cartilage. Les souris utilisées pour l’étude avaient une délétion conditionnelle au cartilage du gène PPARγ. Ces dernières ont été générées en employant le système LoxP/Cre. Les analyses des souris ayant une délétion au PPARγ aux stades embryonnaire et adulte démontrent une réduction de la croissance des os longs, une diminution des dépôts de calcium dans l’os, de la densité osseuse et de la vascularisation, un délai dans l’ossification primaire et secondaire, une diminution cellulaire, une perte d’organisation colonnaire et une diminution des zones hypertrophiques, une désorganisation des plaques de croissance et des chondrocytes déformés. De plus, la prolifération et la différenciation des chondrocytes sont anormales. Les chondrocytes et les explants isolés du cartilage mutant démontrent une expression réduite du facteur de croissance endothélial vasculaire (VEGF)-A et des éléments de production de la matrice extracellulaire. Une augmentation de l’expression de la métalloprotéinase matricielle (MMP)-13 est aussi observée. Dans les souris âgées ayant une délétion au PPARγ, y est aussi noté des phénotypes qui ressemblent à ceux de l’OA tel que la dégradation du cartilage et l'inflammation de la membrane synoviale, ainsi qu’une augmentation de l’expression de MMP-13 et des néoépitopes générés par les MMPs. Nos résultats démontrent que le PPARγ est nécessaire pour le développement et l’homéostasie du squelette. PPARγ est un régulateur essentiel pour la physiologie du cartilage durant les stades de croissance, de développement et de vieillissement.
