Maternal investment in egg production: environmental and population-specific effects on offspring performance in the snapping shrimp Alpheus nuttingi (Schmitt, 1924) (Decapoda, Alpheidae)

Among marine invertebrates, the overall biomass invested in egg production varies widely within populations, which can result from the interaction of endogenous and exogenous factors. Species that have constant reproduction throughout the year can be good models to study the influence of environmental factors on reproductive processes. We conducted a seasonal comparison of egg production in the intertidal snapping shrimp Alpheus nuttingi, which shows a continuous reproductive pattern, to examine the hypothesis that differences in egg production are driven by environmental conditions and population features. This population showed an uncommon strategy, characterized by females that produce eggs of varying sizes within their clutches, with reduced egg volume when the number of eggs is higher (Spring-Summer). In these seasons, higher temperatures and greater food availability may allow the production of more eggs compared to the Autumn-Winter seasons. Compared to other alpheid shrimps, this population produces small eggs, but in larger numbers. Despite the higher fecundity, the reproductive output is relatively low, this production being supported by the large size of females from the southern Atlantic region. Our findings showed that the egg production of A. nuttingi was greatly influenced by environmental factors. Therefore, this shrimp, and probably other decapods that possess continuous reproduction, adopt different reproductive strategies during the year. (C) Koninklijke Brill NV, Leiden, 2010.

A aceitação de alunos com necessidades educativas especiais passados 6 anos da implementação do Decreto-Lei nº3/2008:opinião de educadores de infância e de professores do 1ºciclo

Objetivo: A compreensão da Educação Especial no paradigma da inclusão envolve vontade política e social e mobiliza necessariamente os profissionais de educação, sendo fundamental conhecer a sua opinião. Em Portugal, o Decreto-Lei n.º 3/2008 trouxe mudanças significativas no papel dos docentes do ensino regular, pelo que este estudo tem como objetivo, passados 6 anos da implementação, descrever a opinião de educadores e professores do 1º ciclo acerca da inclusão de alunos com Necessidades Educativas Especiais e conhecer os fatores que justificam as suas opiniões. Método: Foram inquiridos 244 docentes, 122 educadores de infância e 122 professores do 1º ciclo de escolas públicas e privadas, da Área Metropolitana do Porto, os instrumentos usados foram uma folha de caracterização individual e um questionário de vinhetas com descrições do funcionamento de crianças, onde os respondentes se posicionavam, para cada uma, quanto à sua aceitação nas salas. Resultados /Discussão: Os resultados apontam que as vinhetas que descreviam funcionamentos de crianças compatíveis com Perturbação de Espetro de Autismo e Paralisia Cerebral, foram as menos, sendo as justificações a falta de formação e a impossibilidade de despender o tempo necessário devido à exigência de bons resultados académicos. Aferimos que a formação em Educação Especial apenas estava associada à aceitação de alunos com Paralisia Cerebral. Aferimos que a função do docente-educador vs professor do 1ºciclo- apenas é influenciadora de aceitação no caso de alunos com Perturbação de Espetro de Autismo, Paralisia Cerebral e Atraso Global de Desenvolvimento/Dificuldades de Aprendizagem. O facto de se tratar de uma escola pública ou privada influencia a aceitação dos alunos, com os docentes do ensino privado a evidenciarem maior aceitação dos alunos do que os do ensino público.

List of species in the genus Lutzomyia, França, 1924 (Psychodidae, Phlebotominae) from the State of Mato Grosso

This work had the objective of listing the sand fly species that occur in the State of Mato Grosso, Brazil. Data relating to entomological surveys conducted between 1996 and 2004 were obtained from the National Health Foundation and the State Health Department, and this was supplemented with information from research carried out in the state and from the specialized literature. There were records of 106 sand fly species belonging to the genus Lutzomyia. This is a rich and diversified fauna, with some species restricted to forested areas and others recorded throughout the state, independent of the vegetation type, and in areas modified by human action, with predominance of Lutzomyia whitmani.

Synthesis and anticancer activity of N3-substituted-6,8-diaminopurines

[Excerpt] Cancer is the second most common cause of death in developed countries appearing just after cardiovascular diseases. The treatment of cancer remains a major medical challenge and the development of new anticancer drugs is an emerging topic for the scientific community. During the past three decades several chemical classes of anticancer drugs have been identified. In particular, 2,6-diamino purines proved to be important candidates as new anti-cancer agents.

A new and efficient synthesis of N3-cycloalkylamino-6,8-diaminopurines

[Excerpt] The purine core is a privileged scaffold in medicinal chemistry and the biological relevance of purine derivatives makes them attractive targets in the preparation of combinatorial libraries.1,2 In particular, there is a great interest in the synthesis of 8-substituted purines due to their important potential as antiviral and anticancer agents.3 Reports on 8-aminopurines are limited and general methods to obtain these purine derivatives are still needed.4 Cyclic amines and hydrazines are key structural motifs in various bioactive agents.5 Here we report a novel, efficient and inexpensive method for the synthesis of 6,8-diaminopurines 4 incorporating cycloalkylamino substituents at N3position of the purine ring.

A novel and efficient approach to new N3-substituted-6,8-diaminopurines

[Excerpt] Purine nucleobases are fundamental biochemicals in living organisms. They have been a valuable inspiration for drug design once they play several key roles in the cell.1 To the best of our knowledge, reported routes to 8-aminopurines are still scarce due to the difficulty in introducing amino groups in this position of the purine ring. Here we report a novel, inexpensive and facile synthetic method to generate N3,N6-disubstituted-6,8-diaminopurines. In our research group, a number of substituted purines have been obtained from a common imidazole precursor, the 5-amino-4-cyanoformimidoyl imidazole 1. Recently, a comprehensive study on the reactivity of imidazoles 1 with nucleophiles under acidic conditions led us to develop experimental methods to incorporate primary amines into the cyanoformimidoyl group.2 (...)
