The history of the introduction of the giant river prawn, Macrobrachium cf. rosenbergii (Decapoda, Palaemonidae), in Brazil: new insights from molecular data

The giant river prawn, Macrobrachium cf. rosenbergii, is one of the most cultivated freshwater prawns in the world and has been introduced into more than 40 countries. In some countries, this prawn is considered an invasive species that requires close monitoring. Recent changes in the taxonomy of this species (separation of M. rosenbergii and M. dacqueti) require a re-evaluation of introduced taxa. In this work, molecular analyses were used to determine which of these two species was introduced into Brazil and to establish the geographic origin of the introduced populations that have invaded Amazonian coastal waters. The species introduced into Brazil was M. dacqueti through two introduction events involving prawns originating from Vietnam and either Bangladesh or Thailand. These origins differ from historical reports of the introductions and underline the need to confirm the origin of other exotic populations around the world. The invading populations in Amazonia require monitoring not only because the biodiversity of this region may be affected by the introduction, but also because admixture of different native haplotypes can increase the genetic variability and the likelihood of persistence of the invading species in new habitats.

O Grupo Escolar Lauro Sodré em face da política de expansão do sistema escolar no estado do Pará: institucionalização, organização curricular e trabalho docente (1968-2008)

Na presente investigação objetivei compreender a importância das instituições educativas materializadas nos Grupos Escolares criados à época do Brasil Republicano e suas incidências na unidade federativa do Pará, analisando a influência de sua implantação para a organização da sociedade e a formação do cidadão a partir da fundação do Grupo Escolar Lauro Sodré entre o período histórico de 1968 a 2008. Adotou-se como método de pesquisa a análise de documentos, tendo como referencial teórico a pesquisa fundamentada em fontes documentais, iconográficas e bibliográficas, traçando a linha histórica da institucionalização do ensino primário desenvolvido nos Grupos Escolares com sua disseminação e implantação nos municípios, interagindo e modificando as estruturas social, econômica e cultural das cidades, o que levou ao trabalho de reconstrução dos aspectos que envolveram a formação e o trabalho dos docentes pertencentes a tal contexto, a estrutura do currículo e metodologias utilizadas no processo de consolidação da formação institucional primária. Norteado pelas questões problema: Qual a importância das instituições escolares na organização da sociedade e na formação escolar do cidadão brasileiro? Como se efetivou a inserção dos Grupos Escolares no sistema de ensino do Pará e que implicações trouxeram à estrutura social dessa unidade federada segundo os Discursos Governamentais? Qual a importância geopolítica e educacional do Grupo Escolar Lauro Sodré instituído no Município de Moju? Quais eram as prescrições para o exercício do trabalho docente e como se efetivaram as práticas curriculares desses sujeitos nessa instituição? Pois, os Grupos Escolares são identificados primeiro como projeto republicano utilizado para fixar entre a população brasileira os ideais de sua filosofia e ideologias e em outra fase da história como meio de preparar a mão-de-obra para alavancar o progresso do país, destarte essas instituições de ensino tornaram-se espaços de realizações, conflitos e tensões de modo a desvelar as diversas situações que estavam envolvidas em seu contexto.

Investigation of single-strand conformational polymorphism of the TP53 gene in women with a family history of breast cancer

Breast cancer in families with germ line mutations in the TP53 gene has been described in the medical literature. Mutation screening for susceptibility genes should allow effective prophylactic and preventive measures. Using single-strand conformational polymorphism, we screened for mutations in exons 5, 6, 7 and 8 of gene TP53 in the peripheral blood of 8 young non-affected members (17 to 36 years old) of families with a history of breast cancer. Studies of this type on young patients (mean age, 25 years) are very rare in the literature. The identification of these mutations would contribute to genetic counseling of members of families with predisposition to breast cancer. The results obtained did not show any polymorphism indicating mutation. In our sample, the familial tumorigenesis is probably related to other gene etiologies.

Transmissable Dog Cancer Genome Reveals the Origin and History of an Ancient Cell Lineage

Canine transmissible venereal tumor (CTVT) is the oldest known somatic cell lineage. It is a transmissible cancer that propagates naturally in dogs. We sequenced the genomes of two CTVT tumors and found that CTVT has acquired 1.9 million somatic substitution mutations and bears evidence of exposure to ultraviolet light. CTVT is remarkably stable and lacks subclonal heterogeneity despite thousands of rearrangements, copy-number changes, and retrotransposon insertions. More than 10,000 genes carry nonsynonymous variants, and 646 genes have been lost. CTVT first arose in a dog with low genomic heterozygosity that may have lived about 11,000 years ago. The cancer spawned by this individual dispersed across continents about 500 years ago. Our results provide a genetic identikit of an ancient dog and demonstrate the robustness of mammalian somatic cells to survive for millennia despite a massive mutation burden.

Association between interleukin-6 polymorphism in the-174 G/C region and hearing loss in the elderly with a history of occupational noise exposure

Introduction: The biological processes involved in noise-induced hearing loss (NIHL) are still unclear. The involvement of inflammation in this condition has been suggested.Objective: To investigate the association between interleukin - 6 (IL-6) polymorphism and susceptibility to NIHL.Methods: This was a cross-sectional study with a sample of 191 independent elderly individuals aged >60 years of age. Information on exposure to occupational noise was obtained by interviews. Audiological evaluation was performed using pure tone audiometry and genotyped through PCR by restriction fragment length polymorphism - PCR-RFLP. Data were analyzed using the chi-square test and the odds ratio (OR), with the significance level set at 5%.Results: Among elderly with hearing loss (78.0%), 18.8% had a history of exposure to occupational noise. There was a statistically significant association between the genotype frequencies of the IL-6 - 174 and NIHL. The elderly with the CC genotype were less likely to have hearing loss due to occupational noise exposure when compared to those carrying the GG genotype (OR = 0.0124; 95% CI 0.0023-0.0671; p<0.001).Conclusion: This study suggests there is an association of polymorphisms in the IL-6 gene at position - G174C with susceptibility to noise-induced hearing loss.

Genetic history of hepatitis C virus in Pakistan

Hepatitis C virus (HCV) genotype 3a accounts for similar to 80% of HCV infections in Pakistan, where similar to 10 million people are HCV-infected. Here, we report analysis of the genetic heterogeneity of HCV NS3 and NS5b subgenomic regions from genotype 3a variants obtained from Pakistan. Phylogenetic analyses showed that Pakistani genotype 3a variants were as genetically diverse as global variants, with extensive intermixing. Bayesian estimates showed that the most recent ancestor for genotype 3a in Pakistan was last extant in similar to 1896-1914 C.E. (range: 1851-1932). This genotype experienced a population expansion starting from similar to 1905 to similar to 1970 after which the effective population leveled. Death/birth models suggest that HCV 3a has reached saturating diversity with decreasing turnover rate and positive extinction. Taken together, these observations are consistent with a long and complex history of HCV 3a infection in Pakistan. Published by Elsevier B.V.
