The social transition of risk factors for cardiovascular disease in the African region: evidence from three cross-sectional surveys in the Seychelles.

OBJECTIVES: To examine the association between socioeconomic status (SES) and several cardiovascular disease risk factors (CVRFs) and to assess whether this association has changed over a 15-year observation period. METHODS: Three independent population-based surveys of CVRFs were conducted in representative samples of all adults aged 25-64 years in the Seychelles, a small island state located east to Kenya, in 1989 (N=1081), 1994 (N=1067) and 2004 (N=1255). RESULTS: Among men, current smoking and heavy drinking were more prevalent in the low versus the high SES group, and obesity was less prevalent. The socioeconomic gradient in diabetes reversed over the study period from lower prevalence in the low versus the high SES group to higher prevalence in the low SES group. Hypercholesterolemia was less prevalent in the low versus the high SES group in 1989 but the prevalence was similar in the two groups in 2004. Hypertension showed no consistent socioeconomic pattern. Among women, the SES gradient in smoking tended to reverse over time from lower prevalence in the low SES group to lower prevalence in the high SES group. Obesity and diabetes were more common in the low versus the high SES group over the study period. Heavy drinking, hypertension and hypercholesterolemia were not socially patterned among women. CONCLUSION: The prevalence of several CVRFs was higher in low versus high SES groups in a rapidly developing country in the African region, and an increase of the burden of these CVRFs in the most disadvantaged groups of the population was observed over the 15 years study period.

Des hommes en mouvement : vers une reconfiguration des modèles masculins? L'exemple de la Suisse

This project is a study of the men's movement in Switzerland, especially regarding organizations seeking to redefine male identity. So far, this topic has been understudied, in Switzerland. The few studies available on the subject mostly adopt a (pro)feminist perspective. Their main purpose is to criticize men's movement participants. What is more, scarce researches on this problem mostly conducted by members of the Swiss men's movement themselves are mainly descriptive and methodologically problematic. In this context, I initiated the first national and sociological study of the men's movement in Switzerland. My main goals are: firstly, to propose a typology of organizations forming the men's movement in Switzerland. Secondly, I develop a sociological analysis of this phenomenon, taking into account in this process especially the characteristics of the Swiss context. Consequently, I adopted a mixed method approach, which included two main research steps: Firstly, I defined a representative sample of men's movement organizations in Switzerland. Based on a content analysis of men's organizations' websites, I was able to distinguish three ideal-types: Radical Criticism of Masculinity, Criticism of Hegemonic Masculinity, Defense of Men and Traditional Masculinity. Based on these three concepts, I subsequently analyzed the discourse on masculinity amongst men's movement organizations. Secondly, I conducted a survey of men's movement participants. This survey was based on the results of the content analysis. In this particular stage, I mainly used factor analysis. My results show that it would be all too simplistic to characterize the men's movement, in Switzerland, as a criticism of women's emancipation. On the contrary, my analysis reveals a more complex picture: The two main factors, which influence the men's movement, in Switzerland, are the contemporary sociological context and the Swiss society's particular features. I find that male roles, on the one hand, depend very much on today's cultural shift from materialistic to self-expression values. On the other hand, male role models reflect a social adaptation process. Moreover, as a reaction to deep changes in contemporary family structures, I observe an individualization process, characterized by separation between parental and conjugal functions that greatly shapes male role models. - Cette thèse analyse le phénomène des hommes en mouvement, dans le contexte de la Suisse. Cet ensemble est formé d'organisations regroupant des hommes impliqués consciemment dans un processus d'actions et de réflexions sur l'identité masculine. La revue de la littérature révèle qu'en Suisse, le sujet des hommes en mouvement est très peu étudié. Jusqu'ici, les rares recherches s'y intéressant adoptent généralement une approche (pro)féministe, dont l'objectif est de dénoncer ce phénomène. En outre, de rares recherches, issues des acteurs mêmes de ce mouvement, proposent une vue descriptive de l'ensemble, mais souffrant de faiblesses méthodologiques. Par notre recherche, nous souhaitons contribuer à l'étude de ce sujet, en initiant la première étude d'envergure nationale portant sur les hommes en mouvement. L'objectif final est de déboucher sur une typologie des organisations réunissant les hommes en mouvement, puis sur une analyse de la spécificité de cet ensemble, dans le contexte suisse. Pour remplir ces objectifs, nous avons mis en place un dispositif de méthodes mixtes, en deux phases. Lors d'une première étape, nous avons sélectionné un échantillon représentatif de la diversité des organisations masculines. Par une analyse de contenu effectuée sur la documentation récoltée sur les sites Internet de ces dernières, nous avons pu, en utilisant une démarche inductive et qualitative, faire émerger trois idéaux-types : Critique radicale de la masculinité, Critique de la masculinité hégémonique, Défense des hommes et de la masculinité traditionnelle. Ces concepts permettent de rendre compte, de manière schématique, des trois types de discours contemporains sur l'identité masculine diffusés par les hommes en mouvement. Lors d'une seconde étape, nous avons réalisé une enquête auprès des membres des organisations masculines. Pour y parvenir, nous avons créé un questionnaire incluant des propositions élaborées à partir des résultats de l'étape précédente. Lors de cette phase, nous avons réalisé une analyse factorielle. Les résultats montrent que le phénomène du mouvement des hommes ne saurait se réduire, en Suisse, à un mouvement de ressac visant à attaquer les droits des femmes. Au contraire, il s'agit d'un phénomène complexe, fortement dépendant du contexte sociologique contemporain et des caractéristiques de la société helvétique. Nous affirmons, entre autres, que les modèles masculins observables dans cet ensemble sont façonnés, d'une part, par une transition culturelle, caractérisée par le passage des valeurs matérialistes aux valeurs d'expression de soi. D'autre part, les modèles masculins prônés par les hommes en mouvement reflètent un processus d'adaptation sociale. En effet, en réaction au contexte de reconfiguration des formes familiales, on assiste à une individualisation des rapports de filiation et au détachement de la fonction parentale et conjugale, qui imprègnent fortement les modèles masculins défendus par ces hommes.

How central and connected am I in my family? Bridging and bonding social capital in family configurations of young adults with psychiatric disorders

AIMS: This article explores the structures of relational resources that individuals with psychiatric disorders get from their family configurations using the concept of social capital. METHODS: The research is based on a sample of 54 individuals with psychiatric disorders and behavioural problems, and a comparison sample of 54 individuals without a clinical record matched to the clinical respondents for age and sex. Standard measures of social capital from social network methods are applied on family configurations of individuals from both samples. Differences are tested by variance analysis. RESULTS: Structures of family resources available to individuals with psychiatric disorders are distinct. Individuals with psychiatric disorders perceive themselves as less central in their family configurations and less connected to their family members. Their significant family members are perceived as less connected with each other. As a whole, their family configurations are smaller and do not include spouses or partners. Therefore bridging and bonding social capitals are not readily available for them. CONCLUSION: As family configurations of individuals with psychiatric disorders provide fewer relational resources than other families, they are not able to deal with social integration of individuals with psychiatric disorders on their own.

. Phenotype/genotype correlation associated with a novel nonsense Glu20stop mutation in the Rp2 gene in a three-generation family with x-linked retinitis pigmentosa

Purpose: To assess the phenotype of patients in a large 3 generation Swiss family with X-linked retinitis pigmentosa (XLRP) due to a novel nonsense mutation Glu20stop in RP2 gene and to correlate with the genotype. Methods: 6 affected patients (1 male, 5 females, age range: 23 - 73 years) were assessed with a complete ophthalmologic examination. All had fundus autofluorescence images, standardised electroretinography, Goldmann visual fields and Optical Coherence Tomography. In addition, medical records of 2 affected male patients were reviewed. Blood sample was taken for molecular analysis. Results: The male patients were severely affected at a young age with early macular involvement. The youngest 23 y old male had also high myopia and vision of less than 0.05 according to Snellen EDTRS chart bilaterally. All 5 female carriers had some degree of rod-cone dystrophy, but no macular involvement. The visual acuity was 1.0 in the younger carriers, while the 73 years old had VA of 0.5. Two females had mild myopia (range -0.75 to -2) and one had anisometropia of 3.5D, with the more severely affected eye being myopic. Three out of 5 female carriers had optic nerve drusen. Conclusions: We report a novel Glu20stop mutation in RP2 gene, which is a rare cause of XLRP. Our description of severe phenotype in male patients with high myopia and early macular atrophy confirms previous reports. Unlike previous reports, all our female carriers had RP, but not macular involvement or high myopia. The identifiable phenotype for RP2-XLRP aids in clinical diagnosis and targeted genetic screening.

Changes in the Sexual Dimorphism of Triatominae in the Transition from Natural to Artificial Habitats

A shift from large to small average sizes was observed in Triatoma infestans and Rhodnius domesticus between field and domestic (or laboratory) conditions of life. It was more pronounced in the female specimens, leading to a subsequent reduction of sexual size dimorphism. This feature is discussed in terms of genetic and populational changes occurring from natural to artificial habitats, in particular those related to population densities. Sexual size dimorphism is then recommended as a new character to be used in the study of species of Triatominae adapting to domestic ecotopes.

Polar gradients of the DYRK-family kinase Pom1 couple cell length with the cell cycle.

Cells normally grow to a certain size before they enter mitosis and divide. Entry into mitosis depends on the activity of Cdk1, which is inhibited by the Wee1 kinase and activated by the Cdc25 phosphatase. However, how cells sense their size for mitotic commitment remains unknown. Here we show that an intracellular gradient of the dual-specificity tyrosine-phosphorylation regulated kinase (DYRK) Pom1, which emanates from the ends of rod-shaped Schizosaccharomyces pombe cells, serves to measure cell length and control mitotic entry. Pom1 provides positional information both for polarized growth and to inhibit cell division at cell ends. We discovered that Pom1 is also a dose-dependent G2-M inhibitor. Genetic analyses indicate that Pom1 negatively regulates Cdr1 and Cdr2, two previously described Wee1 inhibitors of the SAD kinase family. This inhibition may be direct, because in vivo and in vitro evidence suggest that Pom1 phosphorylates Cdr2. Whereas Cdr1 and Cdr2 localize to a medial cortical region, Pom1 forms concentration gradients from cell tips that overlap with Cdr1 and Cdr2 in short cells, but not in long cells. Disturbing these Pom1 gradients leads to Cdr2 phosphorylation and imposes a G2 delay. In short cells, Pom1 prevents precocious M-phase entry, suggesting that the higher medial Pom1 levels inhibit Cdr2 and promote a G2 delay. Thus, gradients of Pom1 from cell ends provide a measure of cell length to regulate M-phase entry.

The tumour suppressor LATS2 interacts with both Signalosome and E3 ubiquitin ligases : implications in control of cell cycle progression

SUMMARY LATS2 is a member of the Lats tumour suppressor gene family. The human LATS2 gene is located at chromosome 13q11-12, which has been shown to be a hot spot (67%) for LOH in nonsmall cell lung cancer. Both lats mosaic flies and LATS1 deficient mice spontaneously develop tumours, an observation that is explained by the function of LATS1 in suppressing tumourigenesis by negatively regulating cell proliferation by modulating Cdc2/Cyclin A activity. LATS1 also plays a critical role in maintenance of ploidy through its action on the spindle assembly checkpoint. Initial insights into the function of LATS2 reveals that the protein is involved in the G2/M transition of the cell cycle, whereby it controls the phosphorylation status of Cdc25C. The aim of the present study was to identify LATS2 interacting partners that would provide a more thorough understanding of the molecular pathways in which the protein is involved. The yeast two-hybrid system identified a number of candidate genes that interact with LATS2. Most of the interactions were confirmed biochemically by GST-pull down assays that enabled us to demonstrate that LATS2 is an integral component of the Signalosome complex. The Signalosome is thought to be required for the establishment of functional Cullin-based E3 ubiquitin ligases, the substrate-recognition elements of the ubiquitin-mediated protein proteolytic pathway. The findings that LATS2 also interacts with all of the components of the E3 enzymes allows us to postulate that LATS2 is probably involved in the regulation of this Signalosome-E3 super-complex. In addition, the discovery that LATS2 associates with multiple protein kinases localised at the cellular membrane and in various signalling cascades supports the idea that LATS2 functions as an integrator of signals which allows it to monitor the activity of these pathways and translate these signals through its action on the Signalosome. Furthermore, the observation that a kinase-dead LATS2 mutant arrests at the G2/M phase of the cell cycle, demonstrates that the protein, through the action of its kinase domain, is crucial for progression through the cell cycle, an action in accordance to its proposed role as a regulator of E3 ubiquitin ligases. The findings presented herein provide evidence that LATS2 associates with the Signalosome-E3 ubiquitin ligases super-complex which governs protein stability. Any alteration of the protein would have a strong impact on pathways that modulate cell proliferation, as shown by its implication in tumourigenesis. RESUME LATS2 est un membre de la famille de gènes suppresseurs de tumeurs LATS. Le gène humain LATS2 est situé sur le chromosome 13q11-12, une région qui s'est avérée être un point sensible (67%) dans la perte d'hétérozigosité (LOH) notamment pour le cancer du poumon. Le fait que des tumeurs se développent spontanément chez les souris qui sont déficientes pour le gène LATS1 ainsi que dans des cellules mutantes pour LATS chez la Drosophile, est expliqué Par la fonction de LATS1, qui est de supprimer l'apparition de tumeurs en réprimant la prolifération cellulaire à travers sa capacité à réguler l'activité de Cdc2/Cyciine A. LATS1 joue également un rôle important au niveau du maintient de la ploïdie de la cellule, au travers de son action sur les points de contrôle de l'assemblage du fuseau mitotique. Les premières études du gène LATS2 indiquent que la protéine est, par son contrôle des réactions de phosphorylation de la Cdc25C, impliquée dans la transition 021M. Le but de cette étude était d'identifier les protéines qui interagissent avec LATS2, en vue d'obtenir une compréhension plus approfondie des mécanismes moléculaires dans lesquels LATS2 se trouve engagée. Le système de double-hybride chez la levure a permis l'identification d'un grand nombre de gènes qui interagissent avec LATS2. La plupart des interactions ont été confirmées par GST «pull clown», une technique in vitro qui a permis de démontrer que LATS2 est un composant intégral du Signalosome. Ce complexe est supposé réguler l'activité des E3 ubiquitine-rigases, les éléments responsables du recrutement des substrats qui doivent être recyclés par la voie de dégradation ubiquitine-dépendante. Les résultats obtenus indiquent également que LATS2 interagit avec tous les composants des enzymes E3, ce qui nous permet de soumettre l'idée selon laquelle la protéine LATS2 est en fait impliquée dans la régulation du complexe Signalosorne-E3. De plus, la découverte que LATS2 se trouve associée à plusieurs protéines kinases localisées au niveau de la membrane cellulaire, ainsi que dans diverses voies de transduction, confirment l'idée que LATS2 fonctionne en tant que molécule qui intègre les signaux en provenance de ces différentes voies cellulaires. De ce fait, il lui serait possible de coordonner la destruction des protéines au moyen du complexe Signalosome, permettant ainsi de réprimer l'activité des voies de signalisation. En outre, l'introduction d'une mutation dans le domaine kinase de LATS2 résulte en l'arrêt du cycle cellulaire en G2/M, ce qui montre que la protéine, au travers de son domaine kinase, est cruciale pour le bon fonctionnement du cycle cellulaire, ceci en accord avec son rôle proposé comme régulateur des E3 ubiquitine-ligases. Les résultats présentés dans ce manuscrit démontrent que la protéine LATS2 se trouve associée au complexe Signalosome-E3 qui régule la dégradation des protéines. La moindre modification de la protéine engendrerait des répercussions importantes au niveau des voies de transduction qui contrôlent fa prolifération ceilulaire, ce qui atteste du rôle déterminant que joue LAT32 dans la tumorigénèse.

Environmental Regulations in the Hog Farming Sector: A Comparison of Catalonia, Spain and Manitoba, Canada

This article examines the governance structures for managing the location and operation of Intensive Livestock Farming Operations (ILFOs). The article focuses on the hog sector and compares two very different jurisdictions: the Province of Manitoba, Canada and the Autonomous Community of Catalonia, Spain. Both are regions that have witnessed recent increases in hog production, including increasing spatial concentration of ILFOs and increasing size of those ILFOs. Policy has both fostered and sought to manage the increased production. Following a brief background description of restructuring, the changing legislative framework for Manitoba and Catalonia are described. Keywords: environmental regulations, hog farms, manure management, animal feeding operations. JEL: Q15, Q58, R52, O57
