    Based on previous work, we created wide handmade belts as support for a live augmented reality (AR) event. We describe how the garments were made to best meet the constraints of the AR design and how they were used as part of a fashion show and book promotion event. We determined the kind of features the AR software can detect and then created prototypes based on those characteristics. The belt design followed several steps: 1. Computer image preparation; 2. Thread preparation; 3. Thread dyeing; 4. Weaving; 5. Assembly; 6. Photographing the result and retouching the image. The lack of adjustability to deformation was a concern when dealing with clothing and fabric. We resolved this issue by stiffening the fabric. We discuss belts performances well during the live event; other textile techniques as substitutes (e.g. patchwork) and future research prospects

    A locus at 19p13 is associated with breast cancer (BC) and ovarian cancer (OC) risk. Here we analyse 438 SNPs in this region in 46,451 BC and 15,438 OC cases, 15,252 BRCA1 mutation carriers and 73,444 controls and identify 13 candidate causal SNPs associated with serous OC (P=9.2 × 10-20), ER-negative BC (P=1.1 × 10-13), BRCA1-associated BC (P=7.7 × 10-16) and triple negative BC (P-diff=2 × 10-5). Genotype-gene expression associations are identified for candidate target genes ANKLE1 (P=2 × 10-3) and ABHD8 (P<2 × 10-3). Chromosome conformation capture identifies interactions between four candidate SNPs and ABHD8, and luciferase assays indicate six risk alleles increased transactivation of the ADHD8 promoter. Targeted deletion of a region containing risk SNP rs56069439 in a putative enhancer induces ANKLE1 downregulation; and mRNA stability assays indicate functional effects for an ANKLE1 3â€Č-UTR SNP. Altogether, these data suggest that multiple SNPs at 19p13 regulate ABHD8 and perhaps ANKLE1 expression, and indicate common mechanisms underlying breast and ovarian cancer risk

    BRCA1-associated breast and ovarian cancer risks can be modified by common genetic variants. To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were diagnosed with ovarian cancer), with a further replication in an additional sample of 2,646 BRCA1 carriers. We identified a novel breast cancer risk modifier locus at 1q32 for BRCA1 carriers (rs2290854, P = 2.7×10-8, HR = 1.14, 95% CI: 1.09-1.20). In addition, we identified two novel ovarian cancer risk modifier loci: 17q21.31 (rs17631303, P = 1.4×10-8, HR = 1.27, 95% CI: 1.17-1.38) and 4q32.3 (rs4691139, P = 3.4×10-8, HR = 1.20, 95% CI: 1.17-1.38). The 4q32.3 locus was not associated with ovarian cancer risk in the general population or BRCA2 carriers, suggesting a BRCA1-specific associat

    Le Web pour enseigner par projets et favoriser la collaboration

    L’utilisation du Web prĂ©sentĂ©e dans cet article vient appuyer une dĂ©marche pĂ©dagogique fondĂ©e sur le partage des savoirs. Dans le contexte d’une simulation industrielle, les Ă©tudiants d’un cours de programmation avancĂ©e doivent apprendre Ă  partager leur expertise, Ă  communiquer clairement leurs questions, Ă  dĂ©crire des problĂšmes et Ă  faire face Ă  des retournements inattendus. Le Web devient un espace de collaboration pour diffuser les requĂȘtes d’un client fictif, les directives, les travaux prĂ©liminaires et les ententes. Les rĂ©sultats obtenus tendent Ă  suggĂ©rer que cette approche globale force l’étudiant Ă  mieux planifier, l’invite Ă  mieux formuler et dĂ©crire les problĂšmes, augmente le niveau de collaboration et facilite la production d’analogies. Un systĂšme facilitant la logistique entourant la revue par les pairs (rĂ©cupĂ©ration des travaux, construction d’une grille d’évaluation et diffusion des rĂ©sultats) est Ă©galement prĂ©sentĂ©

    Syndromes d’insulino-resistance majeure : clinique et physiopathologie

    No full text
    La rĂ©sistance Ă  l’insuline est une anomalie mĂ©tabolique frĂ©quente. Elle joue un rĂŽle important dans le syndrome mĂ©tabolique (ou syndrome X), le diabĂšte de type 2, l’obĂ©sitĂ©, les syndromes lipodystrophiques plus rĂ©cemment individualisĂ©s survenant au cours des traitements antiviraux de la maladie VIH, et reprĂ©sente un risque cardio-vasculaire prĂ©occupant. Cependant sa physiopathologie reste mal comprise dans ces situations. Les syndromes d’insulino-rĂ©sistance majeure, bien que rares, permettent d’explorer les mĂ©canismes des altĂ©rations de la transmission du message insulinique. Si des mutations du gĂšne du rĂ©cepteur de l’insuline ont ainsi Ă©tĂ© mises en Ă©vidence chez de rares patients, des altĂ©rations post-rĂ©cepteur sont probablement en cause dans d’autres cas. De plus, le rĂŽle de la rĂ©partition corporelle du tissu adipeux semble dĂ©terminant dans l’apparition de l’insulino-rĂ©sistance, comme en tĂ©moigne le tableau clinique des lipodystrophies, congĂ©nitales ou acquises. Cependant, les deux syndromes lipodystrophiques dont la cause molĂ©culaire est connue (la lipodystrophie familiale partielle de Dunnigan, due Ă  des mutations du gĂšne de la lamine A/C, et la lipodystrophie congĂ©nitale gĂ©nĂ©ralisĂ©e liĂ©e Ă  des altĂ©rations de la seipine), ont encore une physiopathologie mystĂ©rieuse. En effet, la lamine A/C est une protĂ©ine nuclĂ©aire ubiquitaire, dont d’autres altĂ©rations conduisent Ă  une myopathie squelettique et/ou cardiaque. Quant Ă  la seipine, d’expression cĂ©rĂ©brale prĂ©dominante, ses fonctions sont encore inconnues. Les avancĂ©es dans la comprĂ©hension de ces syndromes, en particulier les lipodystrophies qui peuvent ĂȘtre considĂ©rĂ©es comme des syndromes mĂ©taboliques caricaturaux, permettront probablement d’éclaicir la physiopathologie de l’insulino-rĂ©sistance plus commune
