Analysis of Body Composition and Food Habits of Spanish Celiac Women

The purpose of the present work was both to analyze composition of Spanish celiac women and to study the food habits and gluten-free diet of these celiac patients, in order to determine whether they achieve a balanced and healthy diet as well as to highlight nutritional qualitative and/or quantitative differences. 54 adult celiac women (34 +/- 13 years) took part in the six-month study. Height, weight and body composition were measured. An analysis of energy consumption and of the macronutrient distribution of their diet was carried out. Their fulfillment of micronutrient intake recommendations was verified. Participants showed a Body Mass Index of 21.6 +/- 2.4 kg/m(2). Energy Intake was slightly lower than the Dietary Reference Intakes. Excessive protein apart from over-consumption of fat was observed. More than three quarters of participants consumed meat in excess. Carbohydrate consumption along with that of fiber was below recommended levels. Vitamin D, iron, and iodine had a low percentage of recommendation compliance. In general, participants followed the recommendations of dairy products and fruit intake whereas vegetable consumption was not enough for the vast majority. We conclude that although the diet of celiac women does not differ much from the diet of general population, some considerations, such as reducing fat and protein consumption and increasing fiber intake, must be taken into account.

Island life in the Cretaceous - faunal composition, biogeography, evolution, and extinction of land-living vertebrates on the Late Cretaceous European archipelago

The Late Cretaceous was a time of tremendous global change, as the final stages of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to marked paleogeographic and faunal changes, before the end-Cretaceous bolide impact. The terrestrial fossil record of Late Cretaceous Europe is becoming increasingly better understood, based largely on intensive fieldwork over the past two decades, promising new insights into latest Cretaceous faunal evolution. We review the terrestrial Late Cretaceous record from Europe and discuss its importance for understanding the paleogeography, ecology, evolution, and extinction of land-dwelling vertebrates. We review the major Late Cretaceous faunas from Austria, Hungary, France, Spain, Portugal, and Romania, as well as more fragmentary records from elsewhere in Europe. We discuss the paleogeographic background and history of assembly of these faunas, and argue that they are comprised of an endemic 'core' supplemented with various immigration waves. These faunas lived on an island archipelago, and we describe how this insular setting led to ecological peculiarities such as low diversity, a preponderance of primitive taxa, and marked changes in morphology (particularly body size dwarfing). We conclude by discussing the importance of the European record in understanding the end-Cretaceous extinction and show that there is no clear evidence that dinosaurs or other groups were undergoing long-term declines in Europe prior to the bolide impact.

Entre tempos antigamente e de hoje em dia: memórias da patrimonialização da viola de cocho

Neste trabalho, procuramos conhecer as memórias da patrimonialização da viola de cocho nas cidades de Cuiabá -Mato Grosso, e Corumbá -Mato Grosso do Sul. Para a realização desse estudo usamos como referência teórica os estudos de memória social sobretudo as discussões desenvolvidos por Bartlett (1932), Halbwachs (1990), Bosi (1994), Portelli (1997) e Sá (2005). Tomando como referência essa abordagem teórica e buscando um entendimento psicossocial das memórias da preservação e patrimonialização do modo de fazer a viola de cocho, buscamos desenvolver a pesquisa por meio de análise documental, observações de campo e entrevistas in loco com mestres pessoas idosas representantes desse saber-, jovens aprendizes e pessoas envolvidas com a patrimonialização desse modo de saber fazer. Revelar as memórias dos entrevistados foi revelar as histórias pessoais e também as memórias coletivas em uma interface com a história narrada do modo de saber fazer a viola de cocho e o conjunto de práticas sociais à ela associadas. Cada entrevistado, ao recordar o momento vivido com esse saber, fez uma reinterpretação pessoal e coletiva e inscreveu suas lembranças na história desse saber ao mesmo tempo em que também traduziu o contexto e a história desse saber em suas memórias de vida. Através das narrativas de mestres, aprendizes e pessoas ligadas a patrimonialização desse saber foi possível conhecer os sentidos e significados atribuídos em diferentes contextos, bem como, as experiências vivenciadas e traduzidas pelos grupos em suas práticas coletivas. Ao tecermos comparações entre as narrativas de mestres e aprendizes foi possível relacionar algumas modificações que as tradições e todo o conjunto de conhecimentos associados ao modo de saber fazer a viola de cocho sofreu e relacionar alguns efeitos sociais dessas mudanças nas formas de ser, de se organizar e de viver destes grupos.

Esporte como experiência : uma análise fenomenológico-pragmática da Constituição do jogo coletivo

O objetivo desse trabalho é compreender a ação humana nos jogos esportivos coletivos. Os jogos em questão são aqueles que são disputados em interações conduzidas pelos jogadores em ações simultâneas mutuamente referidas que envolvem o corpo em um mesmo ambiente ? geralmente esportes com bola, como o futebol, o basquetebol e o voleibol, entre outros. A perspectiva adotada nos conduziu no sentido de compreender a ação no curso da experiência de jogar, uma experiência comumente retratada por praticantes como uma experiência desafiadora, excitante, arrebatadora e autêntica. A realização da ação adequada à lógica dos eventos no sentido de propiciar o alcance das metas e objetivos propostos pelo jogo aos jogadores e à sua equipe, com uma organização e sentido de desafio, conduz e ordena todo o curso da experiência competitiva até o fim da partida ocasionando aquela experiência. Como isso é possível? Para tentar entender como ação e experiência se articulam em uma vivência singular, distinta das demais, na prática dos esportes coletivos, devemos compreender toda a ordem presente na própria constituição do desafio que caracteriza todo o jogo ? uma ordem prática que confere ao ser um impulso contínuo e arrebatador à ação. O jogo, desse modo, é apresentado aqui como um mundo a que corresponde toda uma ordem de existência. Esse mundo, em relação ao qual um modo agonistico de ser se alinha, é ordenado por um conjunto de regras que determina a forma lógica básica da prática competitiva. No modo como foi subjetivada e incorporada pelos jogadores em suas competências, essa forma ordena as interações permitindo que uma dinâmica competitiva real se desdobre fluentemente entre eles numa mesma corrente simultânea e sequencial de eventos que envolvem a todos, sendo vivenciada por cada um no mesmo tempo e no mesmo espaço de uma experiência competitiva nossa. Essa forma se apresenta como ordem de uma mesma realidade contínua, presente tanto numa dimensão predominante espacial e corporal da experiência, envolvendo objetos físicos, no tempo imediato; quanto numa dimensão predominantemente temporal, onde se situa um espaço relacional no qual segue se definindo quem está melhor ou pior e, ao final, o vencedor e o perdedor da partida. Nesse mundo dos jogos agonísticos, ambas as dimensões se mantêm articuladas por mecanismos de definição, acumulação e objetivação numérica dos eventos (como o placar) que são programados para funcionar de acordo com um princípio integrador de justiça, baseados em critérios de excelência e competitividade ? mecanismos cujas operações bem inter-relacionadas devem definir o melhor a cada partida, conferindo à realidade vivenciável nesse mundo um sentido de unidade e completude próprias de uma experiência singular.

O ir-remediável da invenção autobiográfica: desdobramentos do eu na escrita de Caio Fernando Abreu

O trabalho envereda pelos modos e artifícios de construção da subjetividade nos gêneros autobiográficos e nos textos ficcionais, investigando como se dá a escrita que versa sobre o eu. Dos textos abertamente autobiográficos de Caio Fernando Abreu, como a correspondência, passa-se às formas tênues como a crônica e o conto, nos quais se entrecruzam ficção e subjetividade, experiência e invenção. Nesse sentido, estudamos como o sujeito torna-se o centro dos acontecimentos e passa a escrever sobre aquilo que lhe acomete o espírito, o corpo, os sentimentos e pensamentos, seja no registro pontual e objetivo dos acontecimentos ou no floreamento do vivido e do inventado. A intenção é explorar, nos espaços biográficos e literários de Caio Fernando Abreu, o entrelaçamento de vida e grafia, e as possibilidades de escritura de si mesmo em sua correspondência, organizada por Ítalo Moriconi, em Cartas (2002), na coletânea de crônicas Pequenas Epifanias (2006), e nos contos de Ovelhas negras (1995)

Estimates of body sizes at maturation and at sex change, and the spawning seasonality and sex ratio of the endemic Hawaiian grouper (Hyporthodus quernus, F. Epinephelidae)

A case study of the reproductive biology of the endemic Hawaiian grouper or hapu’upu’u (Hyporthodus quernus) is presented as a model for comprehensive future studies of economically important epinephelid groupers. Specimens were collected throughout multiple years (1978–81, 1992–93, and 2005–08) from most reefs and banks of the Northwestern Hawaiian Islands. The absence of small males, presence of atretic oocytes and brown bodies in testes of mature males, and both developed ovarian and testicular tissues in the gonads of five transitional fish provided evidence of protogynous hermaphroditism. No small mature males were collected, indicating that Hawaiian grouper are monandrous (all males are sex-changed females). Complementary microscopic criteria also were used to assign reproductive stage and estimate median body sizes (L50) at female sexual maturity and at adult sex change from female to male. The L50 at maturation and at sex change was 580 ±8 (95% confidence interval [CI]) mm total length (TL) and 895 ±20 mm TL, respectively. The adult sex ratio was strongly female biased (6:1). Spawning seasonality was described by using gonadosomatic indices. Females began ripening in the fall and remained ripe through April. A February–June main spawning period that followed peak ripening was deduced from the proportion of females whose ovaries contained hydrated oocytes, postovulatory follicles, or both. Testes weights were not affected by season; average testes weight was only about 0.2% of body weight—an order of magnitude smaller than that for ovaries that peaked at 1–3% of body weight. The species’ reproductive life history is discussed in relation to its management.

Measurement errors in body size of sea scallops (Placopecten magellanicus) and their effect on stock assessment models

Body-size measurement errors are usually ignored in stock assessments, but may be important when body-size data (e.g., from visual sur veys) are imprecise. We used experiments and models to quantify measurement errors and their effects on assessment models for sea scallops (Placopecten magellanicus). Errors in size data obscured modes from strong year classes and increased frequency and size of the largest and smallest sizes, potentially biasing growth, mortality, and biomass estimates. Modeling techniques for errors in age data proved useful for errors in size data. In terms of a goodness of model fit to the assessment data, it was more important to accommodate variance than bias. Models that accommodated size errors fitted size data substantially better. We recommend experimental quantification of errors along with a modeling approach that accommodates measurement errors because a direct algebraic approach was not robust and because error parameters were diff icult to estimate in our assessment model. The importance of measurement errors depends on many factors and should be evaluated on a case by case basis.

Changes in body composition and fatty acid profile during embryogenesis of quillback rockfish (Sebastes maliger)

We investigated developmental changes in the body compositions and fatty acid (FA) profiles of embryos and preparturition larvae of the quillback rockfish (Sebastes maliger). Comparisons of proximate composition data from early-stage embryos with data from hatched preparturition larvae taken from wild-caught gravid females indicated that embryos gain over one-third their weight in moisture while consuming 20% of their dry tissue mass for energy as they develop into larvae. Lipid contributed 60% of the energy consumed and was depleted more rapidly than protein, indicating a protein-sparing effect. Oil globule volume was strongly correlated with lipid levels, affirming its utility as an indicator of energetic status. FA profiles of early embryos differed significantly from those of hatched larvae. Differences in the relative abundances of FAs between early embryos and hatched larvae indicated different FA depletion rates during embryonic development. We conclude that some metabolically important FAs may prove useful in assessing the condition of embryos and preparturition larvae, particularly 20:4n-6, which cannot be synthesized by many marine fish and which is conserved during embryogenesis. Variability in body composition and energy use among rockfish species should be considered when interpreting any measures of condition.

Reconstruction of original body size and estimation of allometric relationships for the longfin inshore squid (Loligo pealeii) and northern shortfin squid (Illex illecebrosus)

Quantification of predator-prey body size relationships is essential to understanding trophic dynamics in marine ecosystems. Prey lengths recovered from predator stomachs help determine the sizes of prey most influential in supporting predator growth and to ascertain size-specific effects of natural mortality on prey populations (Bax, 1998; Claessen et al., 2002). Estimating prey size from stomach content analyses is often hindered because of the degradation of tissue and bone by digestion. Furthermore, reconstruction of original prey size from digested remains requires species-specific reference materials and techniques. A number of diagnostic guides for freshwater (Hansel et al., 1988) and marine (Watt et al., 1997; Granadeiro and Silva, 2000) prey species exist; however they are limited to specific geographic regions (Smale et al., 1995; Gosztonyi et al., 2007). Predictive equations for reconstructing original prey size from diagnostic bones in marine fishes have been developed in several studies of piscivorous fishes of the Northwest Atlantic Ocean (Scharf et al., 1998; Wood, 2005). Conversely, morphometric relationships for cephalopods in this region are scarce despite their importance to a wide range of predators, such as finfish (Bowman et al., 2000 ; Staudinger, 2006), elasmobranchs (Kohler, 1987), and marine mammals (Gannon et al., 1997; Williams, 1999).

Standard and routine metabolic rates of juvenile sandbar sharks (Carcharhinus plumbeus), including the effects of body mass and acute temperature change*

Standard and routine metabolic rates (SMRs and RMRs, respectively) of juvenile sandbar sharks (Carcharhinus plumbeus) were measured over a range of body sizes (n=34) and temperatures normally associated with western Atlantic coastal nursery areas. The mean SMR Q10 (increase in metabolic rate with temperature) was 2.9 ±0.2. Heart rate decreased with increasing body mass but increased with temperature at a Q10 of 1.8−2.2. Self-paired measures of SMR and RMR were obtained for 15 individuals. Routine metabolic rate averaged 1.8 ±0.1 times the SMR and was not correlated with body mass. Assuming the maximum metabolic rate of sandbar sharks is 1.8−2.75 times the SMR (as is observed in other elasmobranch species), sandbar sharks are using between 34% and 100% of their metabolic scope just to sustain their routine continuous activity. This limitation may help to explain their slow individual and population growth rates, as well as the slow recoveries from overfishing of many shark stocks worl
