An Irish apostle: articulating and actualising apostolicity in the early Irish church

This thesis examines the earliest extant Latin Lives of Brigit and Patrick; Cogitosus’s Vita Brigidae and Muirchú’s Vita Patricii as evidence for a seventh-century debate on Irish apostolicity. While often dismissed as mere propaganda, this thesis shows they are highly sophisticated demonstrations of the continuing connection that Kildare and Armagh had to their patron saints and their authority. It examines the importance of this connection for concepts of ecclesiastical organisation, teaching authority and episcopal succession against the backdrop of the seventh-century Easter question in the Insular Church. This will show that apostolicity was considered to be intrinsically linked with orthodoxy and universality. A textual focus brings forth general patristic themes and ideas that Irish hagiographers evoked through specific words and phrases. The thesis contextualises hagiographical material using evidence from Hiberno-Latin and early Insular exegetical commentaries, referring to major patristic exegetes such as Origen, Jerome, Augustine, and Gregory the Great as support. The introduction discusses the importance of apostolic ideology for the seventh-century Irish Church, and outlines a methodology for examining such abstract themes. The first chapter looks at how developments in apostolic ideology led to ideas of apostolic primacy seen in the Insular material. Chapters two, three, and four examine metaphors of food and feeding, the fountain and the stream, and the head and the body, as significant articulations of apostolicity. Chapter five examines how corporeal relics were understood as the visible proof of this continuity and preserved a saint’s authority for their episcopal heirs. Chapter six looks at how Muirchú engaged with Patrick’s connection to the universal Church and his self-professed lack of disciplina to reconcile his apostolicity with seventh-century norms. Chapter seven places the issues considered thus far in a thoroughly Insular context by examining how the earliest English sources present the Irish legacy in Northumbria after the synod of Whitby. Chapter eight looks at how the text of Patrick’s Confessio in the Book of Armagh relates to a wider seventh-century campaign by Armagh to rehabilitate Patrick’s apostolicity. The conclusion briefly summarizes the thesis, and suggests further avenues for researching this topic in the Insular material

A RELAÇÃO ENTRE RELIGIÃO E SAÚDE NO DISCURSO DE ELLEN G. WHITE (1827-1915)

O objetivo principal da pesquisa encetada foi o de ressaltar a importância do discurso de Ellen White, uma importante líder religiosa do século XIX, nos Estados Unidos da América, para a formação de um estilo e prática de vida, que ainda hoje caracteriza os adventistas do sétimo dia no que se refere a saúde. Outro, não menos importante objetivo, foi o de comparar os principais conceitos de Ellen White sobre saúde e estilo de vida com algumas preocupações científicas e acadêmicas contemporâneas. Para isso, este trabalho mostra como a lista de oito remédios naturais propostos por White sumarizam o ideal de uma vida saudável ainda praticada por milhões de adventistas, 100 anos após a morte de sua Profetiza: ar puro, água, alimentação adequada, luz solar, exercícios físicos, repouso, abstinência, e confiança em Deus. Os conselhos de White foram contrastados com várias práticas culturais que relacionam religião e saúde, levando-nos à conclusão que a cultura adventista tem se mostrado como a mais adequada na salvaguarda da saúde. Isto porque White apresentou uma síntese de elementos da cultura judaica, cristã e ocidental. Nesse sentido, as suas orientações garantem-lhe um lugar privilegiado no movimento de reforma da saúde nos Estados Unidos que ocorreu naquele País na segunda metade do século XIX. Muitos de seus conselhos estão sendo atualmente colocados em prática por todos aqueles que se preocupam com a saúde, longevidade, e a adequação do estilo de vida com as regras inspiradas na natureza e numa espiritualidade sadia.

Tear film surface quality with soft contact lenses using dynamic-area high-speed videokeratoscopy

Objectives. To evaluate the performance of the dynamic-area high-speed videokeratoscopy technique in the assessment of tear film surface quality with and without the presence of soft contact lenses on eye. Methods. Retrospective data from a tear film study using basic high-speed videokeratoscopy, captured at 25 frames per second, (Kopf et al., 2008, J Optom) were used. Eleven subjects had tear film analysis conducted in the morning, midday and evening on the first and seventh day of one week of no lens wear. Five of the eleven subjects then completed an extra week of hydrogel lens wear followed by a week of silicone hydrogel lens wear. Analysis was performed on a 6 second period of the inter-blink recording. The dynamic-area high-speed videokeratoscopy technique uses the maximum available area of Placido ring pattern reflected from the tear interface and eliminates regions of disturbance due to shadows from the eyelashes. A value of tear film surface quality was derived using image rocessing techniques, based on the quality of the reflected ring pattern orientation. Results. The group mean tear film surface quality and the standard deviations for each of the conditions (bare eye, hydrogel lens, and silicone hydrogel lens) showed a much lower coefficient of variation than previous methods (average reduction of about 92%). Bare eye measurements from the right and left eyes of eleven individuals showed high correlation values (Pearson’s correlation r = 0.73, p < 0.05). Repeated measures ANOVA across the 6 second period of measurement in the normal inter-blink period for the bare eye condition showed no statistically significant changes. However, across the 6 second inter-blink period with both contact lenses, statistically significant changes were observed (p < 0.001) for both types of contact lens material. Overall, wearing hydrogel and silicone hydrogel lenses caused the tear film surface quality to worsen compared with the bare eye condition (repeated measures ANOVA, p < 0.0001 for both hydrogel and silicone hydrogel). Conclusions. The results suggest that the dynamic-area method of high-speed videokeratoscopy was able to distinguish and quantify the subtle, but systematic worsening of tear film surface quality in the inter-blink interval in contact lens wear. It was also able to clearly show a difference between bare eye and contact lens wearing conditions.

An exploratory study to evaluate whether medical nutrition therapy can improve dietary intake in hospital patients who eat poorly

Background and aims The Australasian Nutrition Care Day Survey (ANCDS) reported two-in-five patients consume ≤50% of the offered food in Australian and New Zealand hospitals. After controlling for confounders (nutritional status, age, disease type and severity), the ANCDS also established an independent association between poor food intake and increased in-hospital mortality. This study aimed to evaluate if medical nutrition therapy (MNT) could improve dietary intake in hospital patients eating poorly. Methods An exploratory pilot study was conducted in the respiratory, neurology and orthopaedic wards of an Australian hospital. At baseline, percentage food intake (0%, 25%, 50%, 75%, and 100%) was evaluated for each main meal and snack for a 24-hour period in patients hospitalised for ≥2 days and not under dietetic review. Patients consuming ≤50% of offered meals due to nutrition-impact symptoms were referred to ward dietitians for MNT. Food intake was re-evaluated on the seventh day following recruitment (post-MNT). Results 184 patients were observed over four weeks; 32 patients were referred for MNT. Although baseline and post-MNT data for 20 participants (68±17years, 65% females) indicated a significant increase in median energy and protein intake post-MNT (3600kJ/day, 40g/day) versus baseline (2250kJ/day, 25g/day) (p<0.05), the increased intake met only 50% of dietary requirements. Persistent nutrition impact symptoms affected intake. Conclusion In this pilot study whilst dietary intake improved, it remained inadequate to meet participants’ estimated requirements due to ongoing nutrition-impact symptoms. Appropriate medical management and early enteral feeding could be a possible solution for such patients.

Uso da S(+) cetamina por via intra-articular em modelo de osteoartrite em ratos: análise da imunoexpressão da ciclooxigenase 2

A osteoartrite (OA) é uma doença degenerativa que afeta grande parte da população e resulta em significativa morbidade e incapacidade. O presente estudo teve como objetivo investigar os efeitos periféricos da S(+) cetamina na expressão da ciclo-oxigenase 2 (COX-2). Foram utilizados modelos experimentais de osteoartrite em ratos. Inicialmente setenta e dois ratos foram utilizados no estudo. Foram divididos em três grupos de 24 animais cada. Em dois grupos foi induzida a OA através de 2mg de MIA (monoiodo acetato de sódio) por via intra-articular (i.a), em um volume máximo de 50μL e em um dos grupos não foi realizada a indução da OA. No sétimo dia após a indução, dois grupos, incluindo o sem OA, receberam injeção i.a de salina 0,9% em volume máximo de 50μL e o terceiro grupo recebeu injeção de S(+) cetamina na dose de 0,5mg/kg. Nos dias 7, 14, 21 e 28 os animais foram anestesiados e sacrificados para coleta da membrana sinovial e análise imuno-histoquímica da ciclo-oxigenase-2. Durante o estudo ocorreram 29 perdas do material a ser analisado, totalizando um n = 43. O protocolo adotado para a interpretação imuno-histoquímica foi a imunomarcação citoplasmática da COX-2 em células da membrana sinovial, tecido conjuntivo e adiposo, conforme a intensidade da coloração. A análise dos resultados foi realizada através do teste do quiquadrado. A reatividade da COX-2 foi positiva em 53,8% dos animais do grupo sem OA, em 60% do grupo OA com salina e em 80% dos animais do grupo OA com cetamina, sem diferença estatisticamente significante entre os grupos (p = 0,3069). Esse estudo sugeriu que a S(+) cetamina por via intra-articular não inibiu a expressão da COX-2 em modelos de osteoartrite em ratos.

L’effet à long terme de la nutrition parentérale totale néonatale sur le métabolisme énergétique

En raison de la prématurité ou de conditions médicales, un grand nombre de nouveau-nés reçoivent de la nutrition parentérale totale (NPT) en période néonatale. Durant la période d’administration, l’impact métabolique et les effets néfastes de la NPT et celui de son administration avec des sacs exposés à la lumière sont en grande partie connus. Il est admis que des évènements se produisant in utero ou en période néonatale entraînent des modifications métaboliques chez l'adulte. Mais on ignore si la nutrition parentérale possède des effets à long terme. Le but de notre étude est donc d’évaluer l'effet d'une courte période néonatale de NPT sur le métabolisme énergétique de l’adulte. De J3 à J7, des cochons d'Inde sont nourris par NPT dont le sac et la tubulure sont exposés ou protégés de la lumière et sont comparés à des animaux nourris par voie entérale. Après J7, les trois groupes sont nourris de la même façon, par voie entérale exclusivement. Les animaux nourris par NPT montrent une prise pondérale inférieure, un catabolisme plus marqué et des concentrations de substrats énergétiques abaissées (glucose, cholestérol et triglycérides). À 3 mois, le foie des groupes NPT montre des concentrations de triglycérides et de cholestérol abaissées et des changements d'activité enzymatique. La photoprotection de la NPT néonatale diminue la prise pondérale et les concentrations de triglycérides et de cholestérol hépatiques. Notre étude est la première à explorer l’effet à long terme de la NPT néonatale. Elle ouvre la porte à des études humaines qui permettront, nous l’espérons, d’améliorer la prise en charge des nouveau-nés les plus fragiles et les plus immatures.

Caractérisation de l’apoptose observée dans le système limbique après une ischémie myocardique transitoire chez le rat

Au niveau clinique, il a été observé que de 15 à 30 % des patients qui ont subi un infarctus du myocarde développent une dépression majeure. De plus, la population atteinte de dépression post-infarctus présente un risque de mortalité de trois à quatre fois plus élevé, et ce, en comparaison avec la population non dépressive post-infarctus. Dans un modèle de rat développé pour étudier la dépression post-infarctus, des cellules apoptotiques ont été retrouvées au niveau du système limbique. Il apparaît que les cytokines seraient en partie responsables de cette mort cellulaire qui relie le cœur en ischémie et le système nerveux central. Donc, les objectifs de cette thèse sont : 1) de caractériser spatialement et temporellement la survenue de la mort cellulaire par apoptose dans les structures du système limbique du rat, à la suite d’un infarctus du myocarde ; 2) de déterminer l’effet de l’anti-inflammatoire celecoxib sur cette apoptose observée au niveau de l’amygdale et de déterminer l’implication de l’enzyme COX-2 ; 3) de déterminer l’implication de la cytokine pro-inflammatoire TNF-α dans l’apoptose observée au niveau des structures du système limbique du rat, à la suite d’un infarctus du myocarde. Afin d’atteindre ces objectifs, les rats ont subi une ischémie de 40 minutes, suivi d’une période de reperfusion qui varie d’un protocole à l’autre (15 minutes, 24, 48, 72 heures ou 7 jours). De plus, en fonction du protocole, ces rats ont été traités avec soit du célécoxib (inhibiteur sélectif de la COX-2), soit avec du PEG sTNF-R1 (inhibiteur du TNF-α). À la suite de ces protocoles, les rats ont été sacrifiés, la taille de l’infarctus a été déterminée et les différentes structures cérébrales du système limbique prélevées. Des tests biochimiques propres à chaque protocole ont été réalisés afin de documenter l'apoptose. Il a alors été observé qu’aucun des deux traitements ne présentait d’effet sur la taille de l’infarctus. L’étude de l’apoptose dans le système limbique a révélé que : 1) le processus apoptotique se mettait en place dans l’hippocampe dès les 15 premières minutes de reperfusion suivant l’infarctus du myocarde et que ce processus était spatialement dynamique dans le système limbique jusqu’au septième jour postreperfusion ; 2) il est apparu que la COX-2 était impliquée dans l'apoptose du système limbique ; 3) il a été observé que le TNF-α périphérique était impliqué dans ce processus apoptotique après 72 heures de reperfusion en activant la voie extrinsèque de l'apoptose. Ces résultats ont permis de caractériser la survenue de l’apoptose au niveau du système limbique chez le rat à la suite d’un infarctus du myocarde et de documenter l'implication de la COX-2 et du TNF-α dans ce processus. Bien que ces résultats n’apportent pas de schémas thérapeutiques clairs ou de mécanismes physiopathologiques globaux ces derniers permettent une meilleure compréhension de la relation existante entre le cœur et le système nerveux central dans le cadre de l’infarctus du myocarde. De manière moins spécifique ils précisent la relation entre le système inflammatoire et le système nerveux central.

In Vitro and In Vivo Antiplasmodial Activities of Risedronate and Its Interference with Protein Prenylation in Plasmodium falciparum

The increasing resistance of malarial parasites to almost all available drugs calls for the identification of new compounds and the detection of novel targets. Here, we establish the antimalarial activities of risedronate, one of the most potent bisphosphonates clinically used to treat bone resorption diseases, against blood stages of Plasmodium falciparum (50% inhibitory concentration [IC(50)] of 20.3 +/- 1.0 mu M). We also suggest a mechanism of action for risedronate against the intraerythrocytic stage of P. falciparum and show that protein prenylation seems to be modulated directly by this drug. Risedronate inhibits the transfer of the farnesyl pyrophosphate group to parasite proteins, an effect not observed for the transfer of geranylgeranyl pyrophosphate. Our in vivo experiments further demonstrate that risedronate leads to an 88.9% inhibition of the rodent parasite Plasmodium berghei in mice on the seventh day of treatment; however, risedronate treatment did not result in a general increase of survival rates.

Changes in antecedents of BMI between 1976 and 2006

Overweight/obesity has reached epidemic proportions in Australia. This thesis confirmed and extended the relationship between lifestyle and body mass index in that dense energy foods, snacking and low levels of physical activity were associated with higher BMI while plant foods, vegetarianism and, in men, large breakfasts were associated with lower BMI.

Avaliação da atividade antimalárica de extratos obtidos de algas marinhas no litoral do Rio Grande do Norte

Malaria is a major parasitic disease worldwide, accounting for about 500 million cases and causing 2 million to 3 million deaths annually. Four species are responsible for transmitting this disease to humans: Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae and Plasmodium ovale. The parasite resistance to antimalarial drugs and the usual limitations of the vector control implications are contributing to the spread of the disease. The most of significant advances in the search for new antimalarial drugs is based on natural components, the main ones being currently used antimalarial drugs derived from plants. Research on natural products of marine origin (particularly algae) show that some species possess antiplasmodial activity. Knowing that the coast of Rio Grande do Norte is home to several species of algae, the present study was to evaluate, for the first time, the antimalarial activity of ethanolic extracts of seaweed Spatoglossum schroederi, Gracilaria birdiae and Udotea flabellum against Plasmodium falciparum 3D7 strain tests and in vitro using the murine model (Plasmodium berghei) for evaluation in vivo. These species were ground, macerated with ethanol for 24 hours and the extracts concentrated in rotaevaporador (45 ° C ± 5 ° C). For in vitro tests, the extracts were diluted and tested at concentrations between 100 and 1.56 μg/ml (seven concentrations in triplicate), in order to obtain IC50 of each extract. The cytotoxicity tests with macrophages and BGM were performed using the MTT colorimetric assay. BGM macrophages and cells were distributed in 96 wells per plate (1x 105 to macrophages and 1x104 cells per well for BGM) and incubated for 24h at 37 ° C. The ethanol extracts were diluted and tested at concentrations of 100 to 1,56 μg/ml (seven concentrations in triplicate). After periods of 24 hours of incubation with the extracts, 100 μg of MTT was added to each well, and 3 hours elapsed, the supernatant was removed and added 200 μl of DMSO in each well. The absorbance of each well was obtained by reading on a spectrophotometer at 570 nm filter. To evaluate the acute toxicity in vivo, Swiss mice received a single dose (oral) 2000 mg/kg/animal of each extract tested. The parameters of acute toxicity were observed for 8 days. For in vivo tests, Swiss mice were inoculated with 1x105 erythrocytes infected with P. berghei. The treatment was given first to fourth day after infection with 0.2 ml of the extracts in doses of 1000 and 500 mg//g animal. The negative control group received 0.2 ml of 2% Tween-20, whereas the positive control group received sub-dose of chloroquine (5 mg/kg/animal). The assessment of antimalarial activity was done by suppressing suppressing the parasitemia at 5 and 7 days after infection. The growth inhibition of parasites was determined relative to negative control (% inhibition = parasitaemia in control - parasitemia in sample / parasitemia control x 100), the mortality of animals was monitored daily for 30 days The results showed that algae Spatoglossum schroederi and Udotea flabellum showed antimalarial activity in vitro, with reduced parasitemia of 70.54% and 54, respectively. The extracts of the three algae tested showed moderate to high cytotoxicity. Algae S. schroederi and U. flabellum were active against P. berghei only at doses of 500 mg / kg with reduction ranging from 54.58 to 52.65% for the fifth day and from 32.24 to 47.34% for the seventh day, respectively. No toxicity was observed in vivo at the dose tested, over the 8 days of observation. Although preliminary data, the bioactive components in those possible seaweed may be promising for the development of new anti-malarial drugs

Leucograma e teores plasmáticos de proteínas de fase aguda de eqüinos portadores de abdômen agudo e submetidos à laparotomia

Foram examinados 20 eqüinos adultos portadores de abdômen agudo e submetidos à laparotomia. Dez recuperaram-se sem intercorrência pós-operatória (G1) e 10 foram a óbito sete a 10 dias após a cirurgia, com sinais de choque séptico (G2). Avaliaram-se temperatura retal, freqüências cardíaca e respiratória, tempo de preenchimento capilar e teores plasmáticos das proteínas de fase aguda - fibrinogênio, ceruloplasmina, proteína C-reativa, antitripsina, haptoglobina e glicoproteína ácida -, antes e até sete dias após a laparotomia. As leucometrias às 72h e no sétimo dia pós-operatório dos eqüinos que foram a óbito foram, respectivamente, 34,6% e 57,1%, mais altas que a dos animais curados. Os maiores valores de proteína de fase aguda ocorreram no sétimo dia após a cirurgia; os percentuais de elevação de fibrinogênio, antitripsina, glicoproteina ácida, proteína C-reativa, ceruloplasmina e haptoglobina de eqüinos do G2 em relação ao G1 foram 46,8%, 67,9%, 91,9%, 112,2%, 126,9% e 186,2%, respectivamente.

Systemic inflammatory response indicators in rabbits (Oryctolagus cuniculus) experimentally infected with sporulated oocysts of Eimeria stiedai (Apicomplexa: Eimeriidae)

Hemograms and acute-phase proteins in adult male New Zealand White rabbits that had been experimentally infected orally with sporulated oocysts of Eimeria stiedai were evaluated over a 28-day period. Fifty animals were used, divided into two groups: group A infected with 1 x 10(4) sporulated oocysts of E. stiedai and group B inoculated with distilled water. on the seventh day after infection, the infected animals presented anemia and leukocytosis with neutrophilia and monocytosis. Protein fractionation by means of electrophoresis identified 19 acute-phase proteins with molecular weights ranging from 24 to 238 kD. Ceruloplasmin, transferrin and haptoglobin showed high levels on the seventh day after infection, with gradual increases in their concentrations until the end of the experimental period. Thus, from the data of the present study, E. stiedai is considered to be a pyogenic etiological agent for which the infection level can be monitored through the leukocyte count and serum concentrations of ceruloplasmin, transferrin and haptoglobin, and these can be recommended as complementary tests.

Desenvolvimento folicular de embriões de frangos de corte de diferentes genótipos expostos ao estresse térmico crônico

O objetivo do trabalho foi avaliar as alterações tegumentares (morfogênese da pena), em embriões de frangos de corte de linhagens de diferentes padrões de crescimento, obtidos de ovos incubados sob diferentes temperaturas. Os ovos foram obtidos de matrizes das linhagens Cobb 500 e ISA JA57, distribuídos proporcionalmente em três incubadoras. do primeiro (D1) ao sexto dia (D6) de incubação, utilizou-se uma temperatura padrão (37,8°C). A partir do sétimo dia (D7) e até o momento do nascimento aos 21 dias (D21), uma das incubadoras teve a temperatura reduzida para 36,8°C (fria) e uma outra alterada para 38,8°C (quente). A terceira incubadora foi mantida a 37,8°C (controle). O delineamento adotado foi o inteiramente casualizado, em esquema fatorial 3 x 2 (temperatura de incubação e linhagem). A temperatura de incubação e a linhagem não alteraram a densidade dos folículos da pena (número médio de folículos por área de 337,5µm²) nas regiões femural e dorsopélvica dos embriões até os 11 dias (D11). Entretanto, observou-se aumento na densidade folicular na região dorsal dos embriões aos 16 dias (D16) devido ao aumento da temperatura, permanecendo até o momento do nascimento. É possível oncluirque embriões incubados em temperatura acima da recomendada (38,8°C) apresentam uma maior densidade de folículos na região dorsopélvica. Apesar disso, a morfogênese dos folículos permaneceu inalterada.
