Abstract:
Cet article traite de l’évolution des prix de détails dans la grande distribution française suite à la promulgation de la loi Châtel en janvier 2008. Il ressort de cette étude que les relations industrie-commerce témoignent en France d’une concentration stratégique du canal autour d’une structure spécifique de marché, que nous qualifions d’oligopole bilatéral à frange non concurrentielle, consubstantielle d’une hausse générale du prix des produits de détail. En France, le rôle de la structure de marché semble donc un élément plus déterminant que l’évolution législative du cadre réglementaire observée au travers des effets induits par la loi Châtel.

Abstract:
ABSTRACT Previous studies have documented the capacity of European earthworms belonging to the family Lumbricidae to emit the greenhouse gas nitrous oxide (N2O), an activity attributed primarily to the activation of ingested soil denitrifiers. To extend the information base to earthworms in the Southern Hemisphere, four species of earthworms in New Zealand were examined for gut-associated denitrification. Lumbricus rubellus and Aporrectodea rosea (introduced species of Lumbricidae) emitted N2O, whereas emission of N2O by Octolasion cyaneum (an introduced species of Lumbricidae) and emission of N2O by Octochaetus multiporus (a native species of Megascolecidae) were variable and negligible, respectively. Exposing earthworms to nitrite or nitrate and acetylene significantly increased the amount of N2O emitted, implicating denitrification as the primary source of N2O and indicating that earthworms emitted dinitrogen (N2) in addition to N2O. The alimentary canal displayed a high capacity to produce N2O when it was supplemented with nitrite, and alimentary canal contents contained large amounts of carbohydrates and organic acids indicative of fermentation (e.g., succinate, acetate, and formate) that could serve as sources of reductant for denitrification. nosZ encodes a portion of the terminal oxidoreductase used in denitrification. The nosZ sequences detected in the alimentary canals of L. rubellus and O. multiporus were similar to those retrieved from soil and were distantly related to sequences of uncultured soil bacteria and genera common in soils (i.e., Bradyrhizobium, Azospirillum, Rhodopseudomonas, Rhodospirillum, Pseudomonas, Oligotropha, and Sinorhizobium). These findings (i) suggest that the capacity to emit N2O and N2 is a general trait of earthworms and not geographically restricted, (ii) indicate that species belonging to different earthworm families (i.e., Megascolecidae and Lumbricidae) may not have equal capacities to emit N2O, and (iii) also corroborate previous findings that link this capacity to denitrification in the alimentary canal.

Abstract:
Avec le développement des supermarchés en ligne, les consommateurs ont désormais la possibilité d’adopter un comportement multicanal de magasinage alimentaire. Au-delà des interactions entre les expériences vécues sur les différents canaux se pose désormais la question de l’expérience vécue lors du retour en magasin physique. Pour y répondre, ce travail doctoral étudie l’expérience trans-canal de magasinage alimentaire comme cadre conceptuel de recherche, avant d’aborder empiriquement la question du retour en supermarché. En nous basant sur la définition stratégique du trans-canal, nous définissons l’expérience de magasinage trans-canal comme le résultat d’une co-création entre le distributeur et le consommateur, émanant d’un ensemble d’interactions entre un contexte expérientiel élaboré par le distributeur visant à compenser les forces/faiblesses de chaque canal et ; une situation de magasinage et ; un consommateur dont l’objectif est de maximiser la valeur de son expérience holistique et ce ; dans une dynamique cumulative. D’après cette définition impliquant la prise en compte des interactions entre les canaux et la compensation des forces et faiblesses des expériences vécues sur chacun des canaux, nous nous intéressons particulièrement aux variations des dimensions de l’expérience (et de la valeur) lors du retour en magasin suite à l’adoption des supermarchés en ligne. En effet, ces variations pourraient être déterminantes quant à l’élaboration des contextes expérientiels par les distributeurs
[Since grocery retailers offer consumers the opportunity to shop online, the issue of the way consumers live their shopping experience when they return to the store is particulary important. Recent research has already outlined the importance of taking into account the cross effects between channels. Indeed, the development of multichannel strategies has raised a number of challenges around the coordination, the integration, the coherence and the compatibility between channels, in order to develop a cross-channel strategy as a way to sustain retailers’ performance. Consistent with this retail strategy perspective, we study the cross-channel shopping experience. We define it as the way consumers compensate – consciously or not - the weaknesses of experiences lived in one channel with the strengths of other experiences lived in alternative channels in order to optimize their holistic experience with one retailer. Indeed, consumers’ experiences must be studied in a cross-channel perspective, escaping the silos and taking into account the different interactions between the multichannel experiences. In this context, and considering that the cross-channel shopping experience should neutralize the weaknesses and enhance the strengths of each channel, we specifically focus on the experience consumers live when they return to the store. This question is of importance as French grocery retailers have seen negative side effects arising since the development of electronic grocery shopping (diminution of the frequency of visit of physical stores, diminution of non-grocery products sales, cannibalization, etc. )]

Abstract:
The polymeric gel-forming mucins provide the structural framework of saliva and the mucus barriers that cover the mucosal surfaces of the alimentary canal. Dietary compounds may influence the barrier properties of these protective layers. The effects of green tea polyphenols, which have many health benefits but have low bioavailability and contribute to the astringency of green tea, on the structural properties of the mucins in the alimentary canal are investigated here. Using well characterised, highly purified salivary mucins MUC5B and MUC7, and porcine gastric mucins, the effects of the green tea polyphenol epigallocatechin-3-gallate (EGCG) on mucins were studied here. Using rate-zonal centrifugation coupled to agarose gel electrophoresis, atomic force microscopy and particle tracking microrheology, EGCG, at concentrations found in a cup of green tea, caused increased aggregation of MUC5B in human whole saliva, and increased aggregation and viscosity of purified MUC5B. It was revealed using recombinant proteins of the N- and C-terminal regions of MUC5B that EGCG had these effects by aggregating the terminal globular protein domains of MUC5B. In contrast, MUC5B trypsin-resistant high molecular weight glycopeptides were not aggregated by EGCG, demonstrating that the oligosaccharide-rich, highly-glycosylated regions of mucins are not involved in the EGCG-induced aggregation of mucins. EGCG also caused the majority of MUC7 in human whole saliva to aggregate, and purified MUC7 also showed substantial aggregation in the presence of EGCG.Porcine gastric mucins were also used in order to model human gastric mucins. First, the identity of the porcine gastric mucins was explored using tandem mass spectrometry and immunohistochemistry. This revealed that Muc5ac was expressed by the surface epithelium and was the prominent mucin in porcine gastric mucus. Muc6 was expressed by gastric submucosal glands, but was not a major component of the secreted mucus barrier. Porcine Muc5ac and Muc6 were shown to be aggregated by EGCG. These data demonstrate that mucins from both saliva and the stomach are substantially altered by EGCG. This may contribute to the astringency and low bioavailability of EGCG. In contrast, the green tea polyphenol epicatechin (EC) did not cause aggregation of salivary mucins or porcine gastric mucins, suggesting that the galloyl ring of EGCG (which is absent in EC) is important for its aggregation of mucins, and that EC has different mechanisms of astringency. The structure of the mucins in the alimentary canal was studied using Raman spectroscopy, Raman optical activity (ROA) and Tip-enhanced Raman spectroscopy (TERS). The secondary structure of the oligosaccharide-rich regions of mucins was shown to be largely disordered, with some contribution of poly-proline II helix. The N- and C-terminal regions of MUC5B were largely β-sheet in structure, with some disordered structure also present in the C-terminal region. Raman spectroscopy could reliably distinguish between MUC5B glycoforms, demonstrating the sensitivity of this technique to mucin glycosylation and secondary structure. The first TERS spectra along the length of a MUC5B chain are reported, and suggest that patterns may exist in the glycosylation of MUC5B. Therefore, Raman spectroscopies are novel tools that shed new light on mucin structure and in future may be useful for studying the changes to mucin structure during interactions, such as those with polyphenols.

About 10% of the termites’ species have been pointed as agent of some type of damage to the plants. Due to the diversity of food utilization of termites, the characteristics of the digestive tract of the workers and pseudo-workers can be used in systematics and filogenia of these insectes. A control methods of termites is the use of entomopathogenic fungi. Aspects regarding the immunologic response of termites triggered by pathogens invasions, however, remain scarce especially related to the immune reactions deflagrated by the hemocytes. Thus this research focused the following objectives: 1. to identify and to characterize the hemocytes morphology of Nasutitermes coxipoensis (Holmgren) worker´s cast; 2. to generate information about the immunologic reactions of hemocytes when challenged by Metarhizium anisopliae (Metsch.) Sorokin in N. coxipoensis workers and, 3. to describe the histology of workers digestive tractaiming to contribute with support information for systematics of termites. Analysis in light and electronics microscopy of the hemocytes typified the presence of the following cells: Plamatocytes (PL), Granulocytes (GR), Spherulocytes (ES), Prohemocytes (PR), Adipohemocytes (AD) and, Eonocytoids (OE). Among the concentrations from 1x10? to 1x107 conidia/mL of M. anisopliae, the highest concentration 107 conidia/mL was the most efficient with LT50 of 1.62 days. Under this concentration verified greatest frequency of Plamatocytes and Granulocytes in the hemolymph collected during the intervals of from 24 to 72h after application. The hemocitarydynamics during the intervals of 24h, 48h, and 72h after application exhibited significant reduction in Plamatocytes and increasing in Granulocytes. Despite of variation on cell counting was not notified any morphological alterations in the cells. The use of termites spraying as treatment method with 1x107 conidia/mL, in laboratory, triggered the defense mechanisms of N. coxipoensis. The histology of the digestive tract of the workers, in general, exhibited similar characteristics to those observed in other species of termites. Exceptions, however, were identified in the morphology of the epithelial cells regarding the types, number and displaying of these cells in the region of stomodeum as well as the existence of the peritrophic membrane in the region of midgut. Thus these characteristics can be used as criteria for the differentiation among the species of termites of the genus Nasutitermes.
Cerca de 10% das espécies de cupins têm sido apontadas como agente de algum tipo de dano às plantas. Devido ao hábito alimentar variado desses insetos, as características do tubo digestivo dos operários e pseudo-operários são normalmente utilizadas em sistemática e filogenia. Uma alternativa para o controle desses insetos é a utilização de fungos entomopatogênicos. No entanto, os aspectos ligados às reações imunológicas dos insetos promovidas pelas interações com esses patógenos, permanecem ainda bastante escassos, principalmente ao que tange as reações imunes deflagrada pelos hemócitos. Assim a presente pesquisa teve os seguintes objetivos: 1. identificar e caracterizar a morfologia e ultra-estrutura dos hemócitos de operários do cupim Nasutitermes coxipoensis (Holmgren); 2. ampliar as informações sobre as reações imunológicas dos hemócitos quando desafiados imunológicamente por Metarhizium anisopliae (Metsch.) Sorokin. e 3.descrever a histologia do canal alimentar, visando contribuir com informações que possam ser utilizadas na sistemática desse inseto. A análise em microscopia de luz e eletrônica dos hemócitos revelou os seguintes tipos celulares: Plasmatócitos (PL), Granulócitos (GR), Esferulócitos (ES), Prohemócitos (PR), Adipohemócitos (AD) e Oenocitóides (OE). Entre as concentrações de 1x103a 1x107 conídios/mL de M. anisopliae, a concentração mais elevada de 1x107 conídios/mL foi a mais eficiente com TL50 de 1,62 dias. Verificou-se que as células mais freqüentes na hemolinfa foram osPlasmatócitos e os Granulócitos para os tratamentos nos diferentes intervalos de tempo. Analisando a dinâmica hemocitária nos intervalos de 24h, 48h, e 72h, notou-se que os Plasmatócitos reduziram significativamente, enquanto que os Granulócitos aumentaram, após 72h da inoculação. Os Prohemócitos não diferiram estatisticamente nos intervalos de tempos, bem como entre os tratamentos. Durante a contagem diferencial não foram evidenciadas alterações na morfologia dessas células. Assim, a utilização do método de inoculação por pulverização na concentração de 1x107 conídios/mL, em laboratório, mostrou-se eficiente contra os mecanismos de defesa de N. coxipoensis. As características histológicas do canal alimentar dos operários, de modo geral, foram semelhantes as observadas em várias espécies de cupins, porém foram evidenciadas diferenças na morfologia das células epiteliais e tipos de dobras na região do estomodeu, na disposição e númerodos ninhos, bem como a presença da membrana peritrófica na região do mesêntero. Assim essas características podem ser utilizadas como critérios para a diferenciação entre as espécies de cupins do gênero Nasutitermes.

O presente trabalho propôs-se a aprofundar estudos tróficos e ecológicos sobre estratégia alimentar dos peixes abundantes no Canal de Mira da Ria de Aveiro. O estudo foi realizado nas estações da Barra e do Areão, localizadas neste Canal. Foram analisados 1227 estômagos de peixes pertencentes às famílias Atherinidae, Moronidae e Mugillidae, capturados sazonalmente num período compreendido entre Novembro de 2008 ao Junho de 2009. Prestou-se especial atenção ás espécies Atherina boyeri, Dicentrarchus labrax, Liza ramada e Liza aurata, tendo em conta os factores da diversidade, abundância e variedade alimentar de cada espécie. Determinaram-se os índices alimentares e aplicou-se o método gráfico de diagrama modificado de Costello (1996), a fim de interpretar e compreender os hábitos alimentares estabelecidos pelos peixes. Segundo resultados obtidos, as estratégias verificadas foram: carnívora generalista para o Dicentrarchus labrax, invertívora generalista para Atherina boyeri e invertívora especialista para os mugilídeos (Liza ramada e Liza aurata). Determinaram-se cinco grupos principais de presas, sendo, polychaeta, crustácea, insecta, detritos e vegetalia. A análise gráfica e quantitativa da dieta sugere que a maioria dos indivíduos explora vários recursos simultaneamente de acordo com a sua fase do ciclo de vida. Apurou-se a importância ecológica das relações tróficas para as comunidades piscícolas e dos parâmetros físico-químicos para o enriquecimento deste sistema. ABSTRACT: This study aimed to deepen trophic and ecological studies on the feeding strategy of fish abundant in the Mira Chanel, Ria de Aveiro.

Resumo: A Saúde do Trabalhador vem dando atenção à saúde física, mental e psico-social dos cortadores de cana de açúcar pela alta demanda de esforço físico a que são submetidos para cumprir metas de volume de corte, e pelo aumento dos casos de mortes no trabalho. Esta pesquisa teve como objetivo caracterizar as condições de trabalho de migrantes safristas cortadores de cana e avaliar o comportamento nutricional e da composição corporal ao longo da safra, na região de Piracicaba - SP, Brasil. Visou também avaliar a qualidade da dieta e os componentes alimentares deste grupo comparando a ingestão e o gasto energético da jornada de trabalho. Realizamos um estudo descritivo longitudinal em um grupo intencionalmente selecionado de trabalhadores no corte manual de cana, em Elias Fausto, SP. Eles responderam a um questionário sócio-demográfico e permitiram aferir suas medidas antropométricas para o calcularmos o Índice de Massa Corporal, o Percentual de Gordura Corporal e a Circunferência Muscular do Braço em três momentos da safra. Colhemos dados individuais sobre ingestão hídrica, reposição eletrolítica e alimentação durante o período de trabalho, complementados com a descrição qualitativa e quantitativa das marmitas do almoço em três dias distintos por observação direta no local onde as refeições foram preparadas. O gasto energético durante a jornada de trabalho foi comparado com o consumo do mesmo período. Ao final da safra foi retirada amostra de sangue total para dosar Creatino Quinase na isoforma da musculatura esquelética, proteína C reativa e uréia plasmática, como marcadores bioquímicos de inflamação. Acompanhamos durante quatro meses trinta homens migrantes safristas provenientes do Estado do Ceará com idade entre 18 e 44 anos. Os trabalhadores apresentaram perdas significativas de gordura corporal e peso do início até a metade da safra sem recuperação até o final. Todos ganharam massa magra e os de ingresso mais antigo na atividade ganharam menos. Foram encontrados níveis anormais de Creatino Quinase (75,0%) e Uréia (16,7%) entre os safristas. Os cortadores ingeriam no mínimo 5 litros de água por dia e a diluição dos repositores eletrolíticos era feita de forma inadequada. A alimentação foi monótona, com baixa qualidade, fria e diferente dos hábitos alimentares dos trabalhadores. As marmitas apresentaram variação do valor energético entre 1000 e 1300 calorias. Os trabalhadores que consumiram mais energia do que os gastos estimados apresentaram menor perda de percentual de gordura corporal (p=0,03). Encontramos evidências de que o trabalho no corte manual de cana gera perda de peso e de gordura corporal com aumento de massa magra com alterações importantes de marcadores bioquímicos de inflamação crônica e sistêmica. São necessários mais estudos longitudinais nesta população para entender melhor a relação esforço, desgaste, longevidade e saúde no corte de cana. Não é possível afirmar que a quantidade diária total ingerida fosse insuficiente em relação ao gasto, mas a dieta foi monótona e pobre em nutrientes. Estudos adicionais sobre a alimentação desta população poderiam melhorar o manejo dos repositores eletrolíticos para minimizar o desgaste gerado pelo excesso de trabalho
Abstract: The Field of workers' health has paid increasing attention to the physical, mental and psychosocial health of sugar cane manual harvesters due to their high physical efforts to cope with high demands of cutting volume, and by the increasing number of deaths at work. This research aimed at characterizing the working conditions of seasonal harvest migrant workers in the sugar cane crops and also to evaluate their nutritional behavior and body composition along the harvest, in the upstate São Paulo - Brazil. It also aimed to qualitatively evaluate their diet and food components through comparing ingested food with estimated energy expenses during the work days. We conducted a descriptive follow-up study in an intentionally selected group of manual sugar cane cutting in Elias Fausto. They answered to a socio-demographic questionnaire and allowed to take their anthropometric measures to calculate Body Mass Index, Body Fat Composition, and the Arm Muscle Circumference at three timing points during the harvest. We collected individual data on water intake, electrolytic replacement and food intake during the working period, complemented with a qualitative and quantitative description of the meal packages for the lunch in the work field in three different days observing directly the kitchen during its' prepare. The energy consumption during the work day was compared with the parallel intake. At the end of the harvest a sample of total blood was taken to dosing motor muscles isoenzime of creatine kinase, blood protein C and plasma Urea, as biochemical markers for inflammation. We followed-up during four months a group of thirty men migrant harvesters that came from the State of Ceará, aged from 18 to 44 years old. Workers showed significant loss of body fat and weight from the start up to the middle of the harvest without recovery until the end. All men got increased lean muscle mass but those who worked long time in the job got less. Abnormal blood levels among the harvesters were found for creating kinase (75.0%) and for urea (16.7%). The workers drink a minimum of 5 litters of water a day and their way of diluting the electrolytic replacers was inadequate. Available meals were monotonous and with low quality, cold and different from the workers' traditional way of eating. The meal packages contained an estimated energy bulk varying between 1000 and 1300 calories. Workers who ingested more energy than the estimated expenses showed less drop in body fat (p=0.03). Evidences were found that the work in the manual cut of sugar cane harvest generates loss of weight and body fat with increase in muscle mass with important changes in biochemical marchers of systemic and chronic inflammation. Additional longitudinal studies are needed in this population to better understand the relationships among efforts, tear, life extent and health at the sugar cane harvesting. It is not possible to say that the total daily energy intake was enough for the job, but diet was monotonous and poor. Further studies on the nutrition of these workers could allow for better handling of the electrolytic replacement to mitigate the tear generated by the excessive work

Abstract:
Introdução: A preocupação com o bem-estar de aves mantidas em cativeiro vem crescendo no meio científico. As pesquisas etológicas com psitacídeos cativos buscam relatar as mudanças comportamentais desses animais fora de seu ambiente natural, identificando possíveis anormalidades que possam ser corrigidas a fim de contribuir com o desenvolvimento de ambientes melhorados e com a promoção de saúde e bem-estar à essas aves. Objetivo: Este trabalho buscou realizar uma observação preliminar do comportamento de um casal de N. hollandicus mantidos em cativeiro doméstico. Material e Métodos: A metodologia utilizada foi a do animal-focal e de registro contínuo, obtendo a duração dos estados comportamentais avaliados, quais sejam: alimentação, descanso, eliminatório, ingestão de água, movimentação, manutenção, social e vocalização. Utilizou-se um etograma adaptado às condições do experimento. Um esforço amostral total de 12 horas de observação foi atingido ao longo de dois dias, distribuído nos períodos da manhã, tarde e anoitecer. Resultados: Os dados finais foram relativos à média de duração dos comportamentos de ambas aves para o período observado. Obteve-se os resultados de descanso (37%), alimentação (26%), vocalização (12%), movimentação (11%), manutenção (8%), social (4%), ingestão de água (1%) e eliminatório (1%). A literatura relata resultados semelhantes, sugerindo que: a falta de estímulos no cativeiro tende a deixar as aves ociosas, passando a maior parte do tempo inativas; reproduzem com maior frequência os comportamentos alimentares como forma de distração quando estão entediadas e vocalizam em busca de interação; a pouca movimentação pode estar relacionada a falta de possibilidades de exploração do meio não enriquecido; a manutenção das penas, hidratação e eliminatório não pareceram indicar anormalidade; a interação social foi pouco manifestada, embora os psitacídeos sejam indivíduos muito sociáveis. Conclusão: Os resultados sugerem que as aves estejam em uma condição de ociosidade, uma vez que apenas os comportamentos de descanso e alimentação somaram mais da metade do período observado (63%). Análises mais detalhadas são necessárias para avaliar a pouca interação social e compreender a ocorrência de estresse, embora tenha ficado evidente a necessidade de um ambiente melhorado que ofereça possibilidades de ocupação dessas aves e a manifestação de comportamentos relativos ao bem-estar.
