The APC variants I1307K and E1317Q are associated with colorectal tumors, but not always with a family history

Classical familial adenomatous polyposis (FAP) is a high-penetrance autosomal dominant disease that predisposes to hundreds or thousands of colorectal adenomas and carcinoma and that results from truncating mutations in the APC gene. A variant of FAP is attenuated adenomatous polyposis coli, which results from germ-line mutations in the 5′ and 3′ regions of the APC gene. Attenuated adenomatous polyposis coli patients have “multiple” colorectal adenomas (typically fewer than 100) without the florid phenotype of classical FAP. Another group of patients with multiple adenomas has no mutations in the APC gene, and their phenotype probably results from variation at a locus, or loci, elsewhere in the genome. Recently, however, a missense variant of APC (I1307K) was described that confers an increased risk of colorectal tumors, including multiple adenomas, in Ashkenazim. We have studied a set of 164 patients with multiple colorectal adenomas and/or carcinoma and analyzed codons 1263–1377 (exon 15G) of the APC gene for germ-line variants. Three patients with the I1307K allele were detected, each of Ashkenazi descent. Four patients had a germ-line E1317Q missense variant of APC that was not present in controls; one of these individuals had an unusually large number of metaplastic polyps of the colorectum. There is increasing evidence that there exist germ-line variants of the APC gene that predispose to the development of multiple colorectal adenomas and carcinoma, but without the florid phenotype of classical FAP, and possibly with importance for colorectal cancer risk in the general population.

A common evolutionary origin for mitochondria and hydrogenosomes.

Trichomonads are among the earliest eukaryotes to diverge from the main line of eukaryotic descent. Keeping with their ancient nature, these facultative anaerobic protists lack two "hallmark" organelles found in most eukaryotes: mitochondria and peroxisomes. Trichomonads do, however, contain an unusual organelle involved in carbohydrate metabolism called the hydrogenosome. Like mitochondria, hydrogenosomes are double-membrane bounded organelles that produce ATP using pyruvate as the primary substrate. Hydrogenosomes are, however, markedly different from mitochondria as they lack DNA, cytochromes and the citric acid cycle. Instead, they contain enzymes typically found in anaerobic bacteria and are capable of producing molecular hydrogen. We show here that hydrogenosomes contain heat shock proteins, Hsp70, Hsp60, and Hsp10, with signature sequences that are conserved only in mitochondrial and alpha-Gram-negative purple bacterial Hsps. Biochemical analysis of hydrogenosomal Hsp60 shows that the mature protein isolated from the organelle lacks a short, N-terminal sequence, similar to that observed for most nuclear-encoded mitochondrial matrix proteins. Moreover, phylogenetic analyses of hydrogenosomal Hsp70, Hsp60, and Hsp10 show that these proteins branch within a monophyletic group composed exclusively of mitochondrial homologues. These data establish that mitochondria and hydrogenosomes have a common eubacterial ancestor and imply that the earliest-branching eukaryotes contained the endosymbiont that gave rise to mitochondria in higher eukaryotes.

Blurring the lines : how Japanese American internment camps re-defined art and religion's relationship

After the Japanese bombed Pearl Harbor during WWII, anyone of Japanese descent living on the West Coast was placed in internment camps scattered throughout the country. Life inside the camps included many different activities to make life as normal as possible. This study will focus on two intersecting day-to-day activities in particular, the practice of religion within the camps, as well as the creation of art. Art created in the camps was influenced by multiple religious traditions. An analysis of artworks created by professional and amateur artists, interviews and an examination of existing scholarship demonstrates that internment camps created a unique environment for the creation of art. The values of internees reflected the seamless coexistence of Christianity, Buddhism and Shinto in internment camp art.

A cerâmica de cozinha africana de Monte Molião: Monte Molião, Lagos

Monte Molião fica situado na margem esquerda do estuário da Ribeira de Bensafrim, em Lagos. Teve uma ocupação pré-romana, tendo sido densamente povoado durante toda a época romana. Neste trabalho, analisam-se os fragmentos de cerâmica de cozinha africana recolhidos no sítio, em escavações arqueológicas. O conjunto engloba 2005 fragmentos classificaveis, no entanto, apenas 1767 foram passíveis de tipificação (de acordo com as propostas de Tortorella, Hayes e M. Bonifay), tendo sido analisados também de acordo com a sua posição estratigráfica, o que permitiu retirar informação sobre a sua cronologia absoluta e integração nas diferentes fases de ocupação romana do sítio. Todos foram também abordados do ponto de vista do fabrico, concretamente no que se refere à cor e à estrutura física da pasta, numa tentativa de aproximação aos centros produtores. 161 exemplares, considerados representativos do conjunto, foram desenhados e tintados. O circuito da cerâmica de cozinha africana no sul de Portugal foi proposto com base nos dados do sítio de Lagos, mas também com outros provenientes de distintos locais algarvios, tendo-se concluído que aqueles em que esta cerâmica se tinha registado eram litorais ou facilmente acessíveis por rio.

Imagens de África? Filmes e documentários portugueses relativos às antigas colónias africanas (primeira metade do século XX)

Este artigo analisa filmes e documentários, realizados em Portugal, que tiveram como pano de fundo as ex-colónias africanas ou nelas foram inspirados. Durante o Estado Novo, a defesa de uma boa imagem do “império” e da política colonial levou a proibir filmes que incluíssem maus-tratos a indivíduos de origem africana, ilustrassem a luta entre o “branco” (colono) e o “negro” (colonizado), retratassem os movimentos de luta pela ascensão dos negros nos EUA ou exaltassem aspetos pacifistas ou antimilitaristas. Muitos documentários destacam as potencialidades (naturais e humanas) de África. Alguns são dedicados à criação de estruturas de ensino e evangelização dos africanos, ou procuram retratar os seus “usos e costumes”. Outros evidenciam a força de trabalho do africano na construção de um futuro prometedor. Tal trabalho é orientado pelo “branco”, i.e., é ao saber técnico deste que se junta a força do africano. Os africanos são representados como exemplos de um conjunto uno (todos são denominados “indígenas”), mas entre eles procuram-se evidenciar características distintivas. As imagens que denotam modernização, em cidades como Luanda ou Lourenço Marques, ofuscam os “colonizados”. Estes filmes têm amiúde um carácter mais de propaganda do que informação, ou etnográfico, e têm como objetivo transmitir uma consciência colonial.

The natural resources deficit: the implications for German politics. OSW Commentary No. 46, 2011-02-08

Falling amounts of natural resources and the ‘peak oil’ question, i.e. the point in time when the maximum rate of extraction of easily-accessible oil reserves is reached, have been among the key issues in public debate in Germany on all levels: expert, business and – most crucially – the government level. The alarming assessments of German analysts anticipate a rapid shrinkage of oil reserves and a sharp rise in oil prices, which in the longer term will affect the economic and political systems of importer countries. Concerns about the consequences of the projected resource deficit, especially among representatives of German industry, are also fuelled by the stance of those countries which export raw materials. China, which meets 97% of global demand for minerals crucial for the production of new technologies, cut its exports by 40% in summer 2010 (compared to 2009), arguing that it had to protect its reserves from overexploitation. In 2009 the value of natural resources Germany imported reached €84 billion, of which €62 billion were spent on energy carriers, and €22 billion on metals. For Germany, the shrinkage of resources is a political problem of the utmost importance, since the country is poor in mineral resources and has to acquire petroleum and other necessary raw materials abroad1. In autumn 2010, the German minister of economy initiated the establishment of a Resources Agency designed to support companies in their search for natural resources, and the government prepared and adopted a national Raw Material Strategy. In the next decade the policy of the German government, including foreign policy, will be affected by the consequences of the decreasing availability of natural resources. It can be expected that the mission of the Bundeswehr will be redefined, and the importance of African states and current exporter countries such as Russia and China for German policies will increase. At the same time, Germany will seek to strengthen cooperation among importer countries, which should make pressure on resource-exporting states more effective. In this context, it can be expected that the efforts taken to develop an EU resource strategy or even a ‘comprehensive resource policy’ will be intensified; or at least, the EU’s energy policy will permanently include the issue of sourcing raw materials.

The European Union’s Regionalism Diplomacy in Africa: An English School Approach. Bruges Regional Integration & Global Governance Papers [BRIGG] #2.2015

This paper proposes an innovative analytical approach to regionalism promotion by the European Union (EU) in Africa. The approach pursues the dual aim of accommodating African approaches to regionalism in EU foreign policy analysis and of expounding the centrality of diplomacy in negotiating a renewed EU-African Union relationship. The concept of ‘regionalism diplomacy’ brings the negotiated and contentious nature of EU regionalism promotion to the fore. The paper espouses contemporary English School thinking about ‘international society’ and argues that EU regionalism promotion cannot just remain the expansion of European regional international society onto Africa. Instead, EU regionalism diplomacy should acknowledge and incorporate the anticolonial pan-African roots of African regionalism. Overall, the EU should seek a more diplomacy-focused, negotiated Africa-Europe interregional relationship. The paper concludes with an outline of a pan-African approach to regionalism diplomacy and avenues for future research.

Musiciens migrants d'origine arabe dans le contexte montréalais : le parcours de la reconnaissance

Ce mémoire traite des parcours de musiciens migrants d’origine arabe à Montréal. Il s’intéresse à la manière dont ces derniers construisent leurs carrières musicales dans ce contexte et acquièrent la reconnaissance des différents acteurs qu’ils côtoient – pairs, intervenants culturels, public. La méthodologie adoptée est de nature qualitative et correspond à une perspective ethnosociologique, le contexte musical de l’étude inscrivant la démarche dans le domaine de la sociomusicologie. Cinq musiciens ayant migré d’un pays arabe avec une pratique musicale préalable ont été rencontrés, ainsi que cinq acteurs du milieu musical qui interagissent avec eux. Ce corpus d’entretiens a été complété par de l’observation et l’étude de traces (ex. : disques, cv). La démarche d’enquête a permis d’élaborer un ensemble de propositions visant à comprendre les phénomènes sociaux observés. Il apparaît que ces musiciens construisent leurs carrières montréalaises grâce à une actualisation et réappropriation originale des sources et influences musicales accumulées au fil de leur vie, processus néanmoins tributaire des rouages du milieu musical. Celui-ci est constitué de multiples acteurs ayant chacun leurs objectifs, intérêts, contraintes vis-à-vis desquels les musiciens doivent s’ajuster, négocier, faire des compromis. Puis, l’ethnicité arabe qui est construite et mise en scène par les performances musicales peut vraisemblablement agir comme outil pour se démarquer dans le contexte montréalais. Cependant, les dynamiques qui sous-tendent les rapports sociaux que ces artistes entretiennent dans la métropole font en sorte qu’ils ont ultimement peu d’emprise sur la manière dont se manifeste la reconnaissance à leur égard et vis-à-vis de leurs pratiques musicales.
