The MLH1 c.1852_1853delinsGC (p.K618A) Variant in Colorectal Cancer: Genetic Association Study in 18,723 Individuals

Colorectal cancer is one of the most frequent neoplasms and an important cause of mortality in the developed world. Mendelian syndromes account for about 5% of the total burden of CRC, being Lynch syndrome and familial adenomatous polyposis the most common forms. Lynch syndrome tumors develop mainly as a consequence of defective DNA mismatch repair associated with germline mutations in MLH1, MSH2, MSH6 and PMS2. A significant proportion of variants identified by screening these genes correspond to missense or noncoding changes without a clear pathogenic consequence, and they are designated as "variants of uncertain significance'', being the c.1852_1853delinsGC (p.K618A) variant in the MLH1 gene a clear example. The implication of this variant as a low-penetrance risk variant for CRC was assessed in the present study by performing a case-control study within a large cohort from the COGENT consortium-COST Action BM1206 including 18,723 individuals (8,055 colorectal cancer cases and 10,668 controls) and a case-only genotype-phenotype correlation with several clinical and pathological characteristics restricted to the Epicolon cohort. Our results showed no involvement of this variant as a low-penetrance variant for colorectal cancer genetic susceptibility and no association with any clinical and pathological characteristics including family history for this neoplasm or Lynch syndrome.

Compte rendu de la campagne Echobal I n/o Capricorne du 18 âout 1980 au 24 âout 1980

This paper related an echosounding survey located off Côte d'Ivoire in cold season 1980. Biomass mean for the continental platform (20-125m) was 15 metric tons for one square mile.

Avaliação dafitotoxidez de 18 espécies ocorrentes na restinga de Massambaba, Rio de Janeiro

A Área de Proteção Ambiental de Massambaba concentra diversas formações vegetais com uma grande riqueza florística e endemismos. Infelizmente esta área está sujeita à ação antrópica tanto que alguns fragmentos se encontram degradados. Para recuperar ecologicamente esta vegetação é importante compreender os mecanismos de sucessão ecológica. Como se sabe pouco sobre interações entre plantas de restinga, e menos ainda sob o prisma da alelopatia (efeito negativo que uma planta exerce em outras, ao liberar metabólitos secundários para o seu entorno),objetivou-se a realização de ensaios biológicos com espécies nativas. Inicialmente determinamos as melhores condições de extração de metabólitos, e por fim realizamos bioensaios com 18 espécies (Allagoptera aenaria, Andira legalis, Byrsonima sericea, Clusia fluminensis, Couepia ovalifolia, Erythroxylum ovalifolium, Eugenia copacabanensis, Eugenia selloi, Garcinia brasiliensis, Guapira opposita, Maytenus obtusifolia, Myrsine parvifolia, Neomitranthes obscura, Ocotea notata, Pouteria caimito, Renvoizea trinii, Tocoyena bullata e Vitex megapotamica). A aplicação dos extratos foi sobrea germinação e ocrescimento inicial de sementes de alface. Para isso, folhas destas espécies foram coletadas sazonalmente na formação arbustiva aberta não inundável (fácies alta) na restinga de Massambaba para o preparo de extratos aquosos. Os extratos foram obtidos a através da secagem das folhas à60C para posterior maceração, aquecimento, diluição e filtração, obtendo-se as concentrações de 5 e 10% de concentração (peso/volume). Os parâmetros para avaliar a fitotoxidez foram:a porcentagem ea velocidade de germinação e o comprimento da raiz após sete dias de crescimento em placas de Petri umedecidas com os extratos. Além desses três parâmetros, foi utilizado o índice de efeito global, que transforma as três variáveis em um índice único e uma analise de agrupamento (distância euclidiana, método de Ward) para classificá-las em espécies de fraca, média ou alta fitotoxidez de acordo com o valor do índice. A inibição do crescimento foi observada em todas as espécies, e verificou-se diferenças sazonais significativas, com destaque no inverno. Isso sugere que as diferenças os entre níveis de fitotoxidez estejam correlacionada são ambiente e à genética. Se a ação inibitória das espécies com maior efeito alelopático for comprovada, novas estratégias podem ser elaboradas para a reintrodução em projetos de conservação ambiental
