- Roberto Benjamin (org.), A fala e o gesto: ensaios de folkcomunicação sobre narrativas populares, Recife, Imprensa Universitária, 1996, 152 pp.Publication . Correia, PauloApresentando como título uma paráfrase da famosa obra de Leroi-Gourham, este primeiro número da colecção “Pesquisa Académica” é uma colectânea de nove artigos/comunicações resultantes da investigação levada a cabo por Roberto Benjamim e seus alunos do curso de mestrado em comunicação rural da Universidade Federal Rural de Pernambuco. Os estudos abrangem um vasto leque de assuntos que vão desde a preocupação das metodologias de recolha, transcrição e análise de narrativas orais, à apresentação de exemplos de cartas populares pernambucanas analisadas com essa utensilagem.
- About the "Authentic" and the "Spurious"Publication . Jason, HedaThere recently came up some confusion about the distinction between “authentic folk literature” and “non-authentic” folk literature. A discussion seems to be going on about what is “really” authentic and genuine. May humble opinion may add some salt to the discussion (and cloud it still more…):
- Time for change in Portuguese sciencePublication . Canario, Adelino V. M.There is an almost perfect positive relationship between scientific output and gross domestic product (GDP) in Western Europe (Fig. 1). But two countries — Ireland and Portugal — spoil the relationship.
- Highly specific and sensitive non-radioactive molecular identification of Phytophthora cinnamomiPublication . Coelho, A. C.; Cravador, A.; Bollen, A.; Ferraz, J. F. P.; Moreira, A. C.; Fauconnier, A.; Godfroid, EdmondIn response to the need for a faster, more reliable method for identifying Phytophthora cinnamomi in cork oak soils in Portugal, a simple, fast, sensitive molecular identification method is described. It is based on a colorimetric assay which involves an oligonucleotide capture probe covalently immobilised on microtitration wells, a multi-biotinylated oligonucleotide detection probe and the PCR-amplified target DNA. The target DNA is a 349 bp DNA fragment partially covering the 3'-translated and 3'- untranslated regions of the cinnamomin gene. When the specificity of the PCR reaction was evaluated in vitro using isolates of P. cinnamomi and eight other Phytophthora species, including the related P. cambivora, it was specific to P. cinnamomi. When 30 isolates of P. cinnamomi from oak roots in southern Portugal were assayed, 26 gave a strong positive response. The assay has a sensitivity of about 2±5 genome equivalents of P. cinnamomi. The reason for the negative response of four isolates remains unclear.
- Pathogenicity test: a tool to assess disease resistance in Penaeus vannamei post larvaePublication . Baptista, Marina; Dínis, Robles, Rocio Maria TeresaA disease is the sum of the abnormal phenomena displayed by a group of living organisms in association with a specified common characteristic or set of characteristics by which they differ from the norm of their species in such away as to place them at a biological disadvantage. Disease is rarely a simple assossiation between a pathogen and a host shrimp. Usually other circunstances must be presente for active disease to develop in a population. The nutrition is a primary treatment for disease control, by the fact that na organism with nutritional deficiences in more available to the pathogen, because importante factors that are needed for the defense system are lacking. Now a days, nutritional studies regarding the improvement of the diets quality, addition of nutritional supplements and imune enhancers appear to have considerable importance in the control and treatment of disease outbreack.
- El infante delator: modelos patrimoniales, vulgares y virtuales en el romancero tradicionalPublication . Ruiz, Maria JesúsEste trabajo parte de la consideración del personaje romancístico como unidad abierta, sometida -como el género en el que vive- a la herencia y la innovación en cada una de sus re-creaciones. Desde este punto de vista, parece válido afrontar el análisis de determinados arquetipos con el objetivo de comprobar de qué modo se adecúan a las preferencias éticas y estéticas de los diferentes contextos transmisores. Como ensayo de esta propuesta metodológica, el artículo describe el comportamiento de un personaje extremadamente recurrente -el infante delator- en repertorios diferenciados por su situación cronológica y geográfica.
- Biometry and body chemical eomfosition of some Japanese and Eufopean fish gpecles in culturePublication . Santos, Elsa Correia dos; Rosenlund, GretheThe present study considers the relationship between total body weight and other body parameters (length and condition factor), several physiological índices (hepatosomatic índex, gonadosomatic índex, viscerosomatic índex, gut índex and visceral fat) and crude composition (moisture, fat, protein and ash) in yellowtail {Seriola quinqueradiata), amberjack {Seriola purpurascens\ red seabream {Pagrus major), seabream {Sparus aurata) and seabass {Dicentrarchus labrax). The results showed that from the regression equations determined, the weight or percentage of an organ or tissues can be estimated with a high degree of accuracy from the simple knowledge ot body weight. Relating the condition factor with body weight and the parameters with interest to the aquaculturist (percentage of dressed weight, viscerosomatic index, proportion ot visceral tat and of total body fat) in a 3D scatter plot, it was possible to observe how changes in condition, induced by the rearing conditions. affect those parameters, and, consequently, the production levei. The results showed that muscle is the principal site of fat stores in yellowtail, while for seabass, víscera appears to be the principal site, due to the great amount of fat deposited in the abdominal cavity. No conclusions could be made for the rest of the species due to the lack of significant results.
- Adolescer em clausura. Olhares de Aquilino, Régio e Vergílio Ferreira sobre o Romance de InternatoPublication .

- Parathyroid hormone-related protein and somatolactin in sea bream (Sparus aurata) brain and pituitaryPublication . Ingleton, P. M.; Power, Deborah; Canario, Adelino V. M.; Martin, T. J.; Danks, J. A.Parathyroid hormone-related protein (PTHrP) and somatolactin (SL) are both peptides that have been located in PAS+ve pars intermedia (PI) cells of teleost fishes. In mammals and the chick PTHrP is a hypercalcaemic factor causing lysis of bone calcified matrix and inhibiting phosphate excretion via the kidney. Functions of PTHrP in fishes are unknown but SL stimulates phosphate re-absorption by flounder kidney tubule cells1 and low ambient calcium activates PI cells of trout pituitaries.2 It appears possible that both peptides have some similar functions. They only share incidental amino acid homologies, so we have examined brain and pituitaries of sea bream for their distribution using specific antiserum to chum salmon SL (generous gift of H. Kawauchi) and to two regions of human PTHrP (1–16 ) and (50–69).
- Clonagem do gene de matrix gla protein (MGP) da espécie xenopus leavis (Daudin, 1802)Publication . Henriques, Nuno Miguel Carvalho de Sousa de Paula; Cancela, LeonorO presente estudo teve por objectivo principal a identificação e caracterização do gene matrix Gla protein (MGP), na espécie Xenopus laevis (Daudin, 1802).Para o efeito, efectuo-se um rastreio a um banco genómico, utilizando-se como sonda a cadeia de cDNA da MGP específica de Xenopus laevis. Pela purificação dos clones obtidos, isolou-se um fragmento genómico com 4,8 Kb de comprimento, o qual foi sequenciado 1106 bp da sua extremidade 5'. Este fragmento corresponde a parte do gene da proteína, nomeadamente à metade 3' do exão III e intrão 3. Dado o comprimento do clone de DNA genómico isolado, é possível que neste fragmento esteja igualmente localizado o exão IV, actualmente a ser analisado.
