Faunes ichthyologiques du Néogène Supérieur d’Angola, leur âge, remarques sur le Pliocène marin en Afrique Australe

This note is concerned with fish remains from Upper Neogene beds at Farol das Lagostas (and nearby quarry of SECIL) and Baía Farta, mainly recovered by the author in 1960, 1961, 1963 and 1967. For further data see ANTUNES, 1964, pp. 213-215. All the forms identified until now (many of them for the first time) are show in «tableau I». Smaller ones are poorly represented. I. benedeni is provisorily accepted as a distinct species, though it may correspond to a dental morphotype that does exist equally in the extant I. oxyrhinchus (see text): therefore I. benedeni from Farol das Lagostas may after all represent only some dental variations that really belong in the form described as I. cf. oxyrhinchus. The presence of Aprionodon and Hypoprion could not be ascertained: Procarcharodon megalodon, Carcharodon carcharias, Isurus benedeni. Galeocerdo cuvieri, and Carcharhinus sp. I and sp. II are specially discussed. The whole fauna does not correspond either to a very shallow and coastal environment, or to deep waters far away from the coast. It clearly points out to warm waters: an acceptable model would be the fauna from the tropical Atlantic between Northern Angola and Senegal-Cape Verde. The age of this fauna was long regarded as Burdigalian. The data formerly presented (ANTUNES, 1963) that allowed us to ascribe a pliocene age to the uppermost Neogene beds of Farol das Lagostas (Neogene III, ANTUNES, 1964) are reviewed and developed in this paper. This view is corroborated by planctonic foraminifera and stratigraphical data which provide further evidence to prove the presence of miocene beds much younger than Burdigalian, and that some deposits previously correlated to this stage have instead a Plio-Pleistocene age. Fish fauna from Farol das Lagostas is very characteristic, with giant P. megalodon in association with C. carcharias (which predominates, and whose stratigraphical distribution is particularly discussed), and with other very advanced forms like the extant tiger shark, G. cuvieri, enormous I. Benedeni, Hemipristis, and Carcharhinus (whose size largely exceeds the maximum observed with miocene material). With the exception of P. megalodon (extinct) all the other forms show very close affinities, or even identity with modern species. Comparisons with very similar faunas from some South African localities that may also have a Pliocene age are also presented.

Castor fiber na gruta do Caldeirão. Existência, distribuição e extinção do castor em Portugal

Beaver only had been found in Portugal in a Chalcolithic locality, the Vila Nova de S. Pedro castrum. It has now been identified in the Upper Paleolithic (Solutrean) from Gruta do Caldeirão, near Tomar. The species has been found recently at «Gruta do Almonda»; 4 teeth were collected in bed C, older than a Solutrean sequence (see Anexo for details). The species seems to have been rare, as it was also the case with portuguese Miocene Castoridae Enroxenomys minutus and Chalicomys jaegeri. If account is taken of the presence in the Middle Ages until Castille of words meaning beaver (relared to the popular latin Fiber/Biber), it is obvious that these animais still existed then. Such nouns were largely predominant over rhe rather erudite latin (greek deríved) words as Castor,-óris and derived ones, as it could be expected. This allowed us to recognize that veiro should be the corresponding word with Fiber affinities in archaic portuguese. It was previously supposed to mean only expensive furs then imported into Portugal. Indeed it was also a zoonym. Anywày, beaver should be scarce by XIIIth century since it is not included in the quite detailed price list imposed by the «Lei da Almotaçaria» from December 26, 1253 (see Quadro II). Toponyms in veiro and derived words (fig. 2; Quadro III) (plural, feminines, diminutives, inhabited places) give a resrrictive view of rhe Middle Age distribution. Some of them are certainly older than Portugal itself (firsr half of XIlth cenrury); others existed by the XIVth century bur were probably older. Some rare toponyms seem to be derived from the erudite latin Castor,-óris. Nothing suggests that these words were still in use as zoonyms during the Middle Ages. All toponyms are located in regions near rivers and other freshwaters ecologically suitable for beavers, so we can approximately retrace its former, Middle Age disrribution in Portugal (fig. 2; Quadro III). Most of them are locared in the Center-West and Northwest of Portugal, with a suitable c1imate (rainfall in general over 800 mílimerers per year); the only sure geographical exception is Veiros, in Alto Alentejo province, in a region with comparable precipitations and less dry climate conditions than mosr of the territories South of rhe Tagus. There are less and less of these toponyms towards rhe South and the inner part of the country, and they are enrirely lacking in all drier regions from Trás-os-Montes, Beira, Alentejo beyond Tagus' basin, and in Algarve. Nothing suggests beavers lived there, No post-medieval toponym is known, nor any reference after middle XVth century. No such locality was at, or close by to, any frontier. Hence the hypothesis of veiro (et al.} as meaning but points where expensive furs (supposedly known as veiros in general but without c1early saying from what animal they were obrained from) is to be discarded. During the Middle Ages, beaver discriburion concerned all the main river basins from Minho to Tagus ones. Quite rarefied in rhe XIIIth, the beavers may have disappeared from Portugal during the XVth century. Ecological requiremenrs restricted their former distriburion. Vulnerability to natural causes (i.e., severe drought) and to human pressure may have accounted heavily for this species' extinction. Last (1446) reference for Portugal known to us suggests the species was by then almost extinct.

Current mortars in conservation: an overview

Renders are an important item in historical buildings and the need for their periodical re-application is a basic conservation procedure. In modern times there has been a trend towards the replacement of traditional pure lime mortars by new formulations including Portland cement or hydraulic lime. Apart from those interventions on specific and very important monuments, in which the use oftraditional non-hydraulic mortars can be enforced, in most of the projects involving less than first order magnitude heritage the use of some sort of hydraulic components is becoming the rule rather than the exception. The present paper describes and analyses the results of an experimental study with ten formulations of current mortars - including some that can hardly be considered as adequate conservation procedures - allowing a direct comparison in terms of some of the most relevant characteristics.

Implicações imunobiológicas da infecção a herpesvirus em tumores malignos : pesquisa e análise quantitativa de herpesvirus humanos no astrocitoma pilocítico

RESUMO: As infecções virais podem contribuir para o desenvolvimento do cancro, estando vários tumores malignos associados aos Herpesvirus (HHV). O vírus de Epstein-Barr (EBV) e o Herpesvirus 8, dois Herpesvirus, foram reconhecidos como agentes etiológicos de várias neoplasias. O astrocitoma pilocítico do cerebelo é um dos tumores cerebrais mais frequentes na criança, adolescentes e jovens adultos e a proliferação astrocitária ocorre geralmente após vários tipos de agressão, nomeadamente a infecção viral. Para investigar esta eventual interligação, estudámos 35 astrocitomas pilocíticos, pesquisando a presença dos 8 Herpesvirus. Neste estudo, foram utilizadas 10 amostras de biópsias do cerebelo de doentes que faleceram por doenças não relacionadas com infecção ou patologia tumoral. A maioria dos astrocitomas (33) eram tumores de baixa malignidade. As amostras foram analisadas por PCR (Polymerase Chain Reaction) quantitativa em tempo real (qPCR), com amplificação do gene da DNA polimerase viral. Treze astrocitomas e 7 controles revelaram pequenas quantidades de DNA viral (1-100 cópias/100ng DNA) de todos os Herpesvirus, com excepção do HHV6 A e B que estava ausente nas amostras. O EBV foi identificado em 9 dos 35 astrocitomas (26%) e em 7 dos 10 controles (70%) estando muito mais presente nos controles. As amostras positivas para o EBV foram também analisadas por imunohistoquímica, não tendo sido imunoreactivas para os anticorpos utilizados. A PCR com CODEHOP (consensus-degenerated hybrid oligonucleotide primers) foi utilizada para investigar a presença de um eventual Herpesvirus novo nestas amostras. Não foi identificada nenhuma sequência indicativa de um novo HHV por este método. 24. Em conclusão, os dados apontam para a presença de Herpesvirus, com particular relevância para o EBV, em tecido de cerebelo normal e em tumores cerebrais, embora em níveis demasiado baixos para poderem ser responsabilizados pela indução tumoral. A presença de sequências de DNA de Herpesvirus, nomeadamente do EBV, no Sistema Nervoso Central vem enriquecer a discussão sobre o significado da infecção viral na oncogénese humana, particularmente na neuro-oncogénese. ABSTRACT: Viral infections can contribute to the development of human cancer. Several human malignancies are linked with Human Herpesviruses (HHVs). Epstein-Barr virus and HHV8, two hHerpesvirus, have been recognized as etiologic agents of several neoplasms. Pilocytic astrocytoma of the cerebellum is one of the most common brain tumour in children, adolescents and young adults and astrocytary proliferation generally occurs after several types of injury, namely viral infection. To further explore this association, we have searched the tissue from 35 pilocytic astrocytoma, for all the 8 HHV. In this study, ten brain biopsies (cerebellum) from patients who died of unrelated diseases were used as controls. Most of the astrocytomas (33) were of low grade malignity. Samples were assessed by Real-time quantitative Polymerase Chain Reaction (q PCR) amplification of viral DNA polymerase gene. Thirteen astrocytoma and 7 controls showed low viral DNA levels (1-100 copies/100ng DNA) for all HHVs, with the exception of HHV6 that was absent. EBV was identified in 9 of the 35 astrocytoma (26 %) and in 7 of the 10 controls (70%) being more present in controls. EBV positive samples were also assessed by Immunohistochemistry (IHC) but none showed immunoreactivity for the antibodies used. PCR with consensus-degenerated hybrid oligonucleotide primers (CODEHOP) were also used to look for novel HHVs in these samples and no sequence indicative of a new HHV was detected. 26 Altogether the data indicate the presence of HHVs, with relevance for EBV in normal cerebellum tissue and also in brain tumours but at too low levels to be considered responsible for tumour induction. The presence of HHV DNA sequences, particularly EBV, in the studied brain tumours and control samples, further enriches the discussion about the relevance of viral infection in human oncogenesis, particularly neuro-oncogenesis.RÉSUMÉ: Les infections virales peuvent contribuer au développement du cancer. Les vírus de type Herpès sont associés à plusieurs néoplasies. Il est par exemple établi que les vírus Epstein-Barr et « human Herpesvirus 8 » (HHV-8) sont responsables de plusieurs tumeurs malignes. L´astrocytome pilocitique du cervelet est l’une des tumeurs les plus fréquentes chez les enfants, adolescents et adultes jeunes. En général la prolifération des astrocytes se produit en réponse à une agression. Posant l’hypothèse d’une agression d’origine virale, nous avons recherché la présence des 8 vírus Herpès dans les tissus de 35 astrocytomes. Dans cette étude, 10 échantillons de biopsie de cervelet de patients décédés suite à d’autres pathologies, ont été utilisés comme contrôles. La majorité des astrocytomes étaient de très basse malignité. Les échantillons ont été étudiés par PCR quantitative en temps réel, en amplifiant le gène de l’ADN-polymérase virale. Treize astrocytomes sur 35 (37%) et 7 contrôles sur 10 (70%) ont été trouvés positifs pour tous les HHV sauf l´HHV6, toujours avec un nombre de copies de polymérase virale bas (< 100 copies/100 ng d’ADN). Notamment l’EBV a été identifié 7 fois dans les contrôles (70%) et 9 fois dans les astrocytomes (26%). Les échantillons positifs pour l`EBV ont aussi été étudiés par immuno-histochimie. Aucun signal n’a été observé avec les anticorps utilisés. Enfin, une technique de PCR avec oligonucléotides dégénérés (CODEHOP ou consensus degenerated hybrid oligonucleotide primers) a été utilisée pour rechercher la présence d´un éventuel nouveau vírus Herpès dans les échantillons d’astrocytome. Aucun nouveau vírus n’a été identifié. 28 En résumé, nous avons établi la présence de vírus Herpès, en particulier l´EBV, dans le cervelet normal et dans les tumeurs du cerveau. Les quantités d’ADN viral retrouvées sont faibles et ne permettent pas d’attribuer à ces vírus la responsabilité de l’induction des tumeurs. Cependant, la présence d’ADN de vírus Herpès dans le cerveau sain ou pathologique vient enrichir la discussion sur le signification de l´infection virale dans les processus d´oncogenèse en général, et dans la neuroonco-genèse en particulier.

Adherence to health-related behaviors: effectiveness of implementation intentions and posthypnotic suggestion in college students

Resumo: Com base no conceito de implementação de intenções (Gollwitzer, 1993, 1999) e na teoria do contexto de resposta de Kirsch & Lynn (1997), o presente trabalho testou a eficácia de uma intervenção combinada de implementação de intenções com hipnose e sugestão pós-hipnótica na promoção da adesão a uma tarefa simples (avaliação do humor) e uma tarefa difícil (actividade física). Os participantes são estudantes universitários de uma universidade na Nova Jérsia, (N=124, Estudo 1, EUA) e em Lisboa (N=323, Estudo 2, Portugal). Em ambos os estudos os participantes foram seleccionados a partir de uma amostra mais vasta baseado num escrutínio da sua sugestibilidade hipnótica avaliada por meio da Escala de Grupo de Sugestibilidade Hipnótica de Waterloo-Stanford (WSGC): Forma C. O Estudo 1 usou um desenho factorial do tipo 2x2x3 (tipo de intenção formada x hipnose x nível de sugestionabilidade) e o Estudo 2 usou um desenho factorial do tipo 2 x 2x 2 x 4 (tipo de tarefa x tipo de intenção formada x hipnose x nível de sugestionabilidade). No Estudo 1 foi pedido aos participantes que corressem todos os dias e durante três semanas durante 5 minutos, que medissem a sua pulsação antes e depois da actividade física e que mandassem um e-mail ao experimentador, fornecendo assim uma medida comportamental e uma medida de auto-relato. Aos participantes no grupo de intenções de meta foi apenas pedido que corressem todos os dias. Aos participantes no grupo de implementação de intenções foi pedido que especificasses com exactidão quando e onde iriam correr e enviar o e-mail. Para além disso, cerca de metade dos participantes foram hipnotizados e receberam uma sugestão pós-hipnótica em que lhes foi sugerido que o pensamento de correr todos os dias lhes viria à mente sem esforço no momento apropriado. A outra metade dos participantes não recebeu qualquer sugestão hipnótica. No Estudo 2 foi seguido o mesmo procedimento, mas a cerca de metade dos participantes foi atribuída uma tarefa fácil (enviar um Adherence to health-related behaviors ix SMS com a avaliação diária do seu estado de humor naquele momento) e à outra metade da amostra foi atribuída a tarefa de exercício físico atrás descrita (tarefa difícil). Os resultados do estudo 1 mostraram uma interacção significativa entre o nível de sugestionabilidade dos participantes e a sugestão pós-hipnótica (p<.01) indicando que a administração da sugestão pós-hipnótica aumentou a adesão nos participantes muito sugestionáveis, mas baixou a adesão nos participantes pouco sugestionáveis. Não se encontraram diferenças entre os grupos que formaram intenções de meta e os que formaram implementação de intenções. No Estudo 2 os resultados indicaram que os participantes aderiram significativamente mais à tarefa fácil do que à tarefa difícil (p<.001). Os resultados não revelaram diferenças significativas entre as condições implementações de intenções, hipnose e as duas estratégias combinadas, indicando que a implementação de intenções não foi eficaz no aumento da adesão às duas tarefas propostas e não beneficiou da combinação com as sugestões pós-hipnóticas. A utilização da hipnose com sugestão pós-hipnótica significativamente reduziu a adesão a ambas as tarefas. Dado que não existiam instrumentos em Português destinados a avaliar a sugestionabilidade hipnótica, traduziu-se e adaptou-se para Português Escala de Grupo de sugestibilidade hipnótica de Waterloo-Stanford (WSGC): Forma C. A amostra Portuguesa (N=625) apresentou resultados semelhantes aos encontrados nas amostras de referência em termos do formato da distribuição dos padrões da pontuação e do índice de dificuldade dos itens. Contudo, a proporção de estudantes portugueses encontrada que pontuaram na zona superior de sugestionabilidade foi significativamente inferior à proporção de participantes na mesma zona encontrada nas amostras de referência. No sentido de lançar alguma luz sobre as razões para este resultado, inquiriu-se alguns dos participantes acerca das suas atitudes face à hipnose utilizando uma versão portuguesa da Escala de Valência de Atitudes e Crenças face à Hipnose e comparou-se com a opinião de Adherence to health-related behaviors xAbstract: On the basis of Gollwitzer’s (1993, 1999) implementation intentions’ concept, and Kirsch & Lynn’s (1997) response set theory, this dissertation tested the effectiveness of a combined intervention of implementation intentions with hypnosis with posthypnotic suggestions in enhancing adherence to a simple (mood report) and a difficult (physical activity) health-related task. Participants were enrolled in a university in New Jersey (N=124, Study 1, USA) and in two universities in Lisbon (N=323, Study 2, Portugal). In both studies participants were selected from a broader sample based on their suggestibility scores using the Waterloo-Stanford Group C (WSGC) scale of hypnotic susceptibility and then randomly assigned to the experimental groups. Study 1 used a 2x2x3 factorial design (instruction x hypnosis x level of suggestibility) and Study 2 used a 2 x 2x 2 x 4 factorial design (task x instructions x hypnosis x level of suggestibility). In Study 1 participants were asked to run in place for 5 minutes each day for a three-week period, to take their pulse rate before and after the activity, and to send a daily email report to the experimenter, thus providing both a self-report and a behavioral measure of adherence. Participants in the goal intention condition were simply asked to run in place and send the e-mail once a day. Those in the implementation intention condition were further asked to specify the exact place and time they would perform the physical activity and send the e-mail. In addition, half of the participants were given a post-hypnotic suggestion indicating that the thought of running in place would come to mind without effort at the appropriate moment. The other half did not receive a posthypnotic suggestion. Study 2 followed the same procedure, but additionally half of the participants were instructed to send a mood report by SMS (easy task) and half were assigned to the physical activity task described above (difficult task). Adherence to health-related behaviors vii Study 1 result’s showed a significant interaction between participant’s suggestibility level and posthypnotic suggestion (p<.01) indicating that posthypnotic suggestion enhanced adherence among highly suggestible participants, but lowered it among low suggestible individuals. No differences between the goal intention and the implementation intentions groups were found. In Study 2, participants adhered significantly more (p<.001) to the easy task than to the difficult task. Results did not revealed significant differences between the implementation intentions, hypnosis and the two conditions combined, indicating that implementation intentions was not enhanced by hypnosis with posthypnotic suggestion, neither was effective as single intervention in enhancing adherence to any of the tasks. Hypnosis with posthypnotic suggestion alone significantly reduced adherence to both tasks in comparison with participants that did not receive hypnosis. Since there were no instruments in Portuguese language to asses hypnotic suggestibility, the Waterloo-Stanford Group C (WSGC) scale of hypnotic susceptibility was translated and adapted to Portuguese and was used in the screening of a sample of college students from Lisbon (N=625). Results showed that the Portuguese sample has distribution shapes and difficulty patterns of hypnotic suggestibility scores similar to the reference samples, with the exception of the proportion of Portuguese students scoring in the high range of hypnotic suggestibility, that was found lower than the in reference samples. In order to shed some light on the reasons for this finding participant’s attitudes toward hypnosis were inquired using a Portuguese translation and adaptation of the Escala de Valencia de Actitudes y Creencias Hacia la Hipnosis, Versión Cliente, and compared with participants with no prior hypnosis experience (N=444). Significant differences were found between the two groups with participants without hypnosis experience scoring higher in factors indicating misconceptions and negative attitudes about hypnosis.
