El impacto audiovisual en la enseñanza de la literatura.

Realizado en la Universidad de Salamanca por cinco profesores del Departamento de Filología Inglesa. Los objetivos han sido demostrar que el medio audiovisual, concretamente le cinematográfico, es un excelente recurso didáctico para las asignaturas de literatura y formar un aula permanente de material audiovisual, así como el estudio y elaboración de dicho material de modo que permita el enfoque didáctico propuesto. El sistema de trabajo se ha basado en la selección de un corpus cinematográfico en formato de video y el tratamiento y análisis del mismo por parte de los miembros del grupo de trabajo de acuerdo con los objetivos apuntados. Cada uno de los miembros se ha centrado en aspectos de la relación entre cine y literatura que pueden ser de interés para la didáctica de la literatura, por ejemplo las obras de teatro en el cine, las adaptaciones de obras literarias al medio cinematográfico, la utilización de películas para estimular la discusión y análisis de obras literarias, etc. El resultado ha sido la elaboración de un conjunto de materiales que, utilizados en la clase de literatura, tienden a favorecer el aprendizaje de los alumnos y potenciar la dimensión práctica de la enseñanza literaria, es decir, la lectura y el estudio de las obras concretas, tales materiales han sido ya contrastados en un ciclo de cine realizado como apoyo de algunas asignaturas del plan de estudios de Filología Inglesa de la Universidad de Salamanca, y lo serán de nuevo tras las modificaciones y ampliaciones oportunas, en cursos y asignaturas que se implantarán próximamente.

Agricultural tenancies: implied surrender and regrant and the operation of the Agricultural Tenancies Act 1995

Agricultural tenancies arising after 1st September 1995 are mostly governed by the Agricultural Tenancies Act 1995. As such, tenants under this Act do not benefit from the degree of protection conferred on tenancies already in existence, which remain under the Agricultural Holdings Act 1986. Section 4 of the 1995 Act seeks to protect those tenancies which subsequently inadvertently undergo a surrender and regrant and which would otherwise lose the protection of the 1986 Act. This paper seeks to investigate, by relating recent case law and statute to the situation of agricultural tenancies, the occasions where surrender and regrant might occur and whether in such instances the protection of the 1986 Act will be lost.

Analgesia em pós-operatório de toratomias : estudo prospectivo e randomizado

Introdução: A dor é um importante fator de incremento da morbidade e mortalidade em pacientes submetidos a procedimentos cirúrgicos que incluem toracotomias. Diversos fatores contribuem para que esses pacientes apresentem um alto grau de dor no pós-operatório, entre os quais a secção da pele, músculos e pleura, retração dos músculos e ligamentos pelo afastador de Finochietto, irritação da pleura e nervos intercostais pelos drenos tubulares torácicos e fraturas ocasionais dos arcos costais. O aumento das taxas de morbidade e mortalidade é dado principalmente à respiração superficial decorrente da pouca mobilidade da parede torácica e conseqüente à dor e pela perda da efetividade do principal mecanismo de eliminação de secreções da árvore traqueobrônquica (tosse), resultando em atelectasias, inadequado gradiente ventilação / perfusão, hipoxemia e pneumonia. Uma vez caracterizada a necessidade de atenuação da dor como fator primordial na melhora dos índices de morbidade e mortalidade no período pós-operatório de cirurgia torácica, torna-se imperiosa uma análise das terapêuticas disponíveis na atualidade para tanto. Objetivos: Avaliar a utilização de três diferentes métodos de analgesia: 1. bloqueio peridural com morfina (BPM); 2. morfina parenteral (MP); e 3. bloqueio intercostal extrapleural contínuo com lidocaína” (BIC), em pacientes submetidos a procedimentos que incluíram toracotomias em sua execução, além de analisar o custo financeiro desses métodos. Materiais e métodos: Trata-se de um estudo prospectivo, randomizado, no qual foram analisados 79 pacientes, submetidos a toracotomias, subdivididos de forma aleatória em três grupos, de acordo com a modalidade terapêutica instituída: 25 pacientes no grupo BIC, 29 pacientes no grupo BPM e 25 pacientes no grupo MP. Cada paciente foi observado e analisado por profissionais de enfermagem previamente treinados. As variáveis analisadas foram a dor e a sedação. (quantificadas através de escores e analisadas através do método de Kruskal-Wallis com correção pelo teste de Dunn), além do custo financeiro de cada método e da necessidade de administração de opióides adicionais. Resultados: As variáveis dor e sedação foram obtidas através das seguintes medianas, respectivamente: grupos BIC (2,5 e 0); BPM (4 e 0) e MP (3,5 e 0). O custo financeiro foi de US$ 78,69 para o grupo BIC; US$ 28,61 para o grupo BPM e US$ 11,98 para o grupo MP. A necessidade adicional de opióide foi de 4,2 mg/dia para o grupo BIC; 5,7 mg/dia para o grupo BPM e 10,7 mg/dia para o grupo MP. Conclusões: A intensidade da dor foi significativamente menor no grupo BIC, quando comparado ao grupo MP. Não foram identificadas diferenças significativas de intensidade da dor quando comparados os grupos BIC versus BPM e BPM versus MP. A intensidade de sedação foi significativamente maior no grupo MP quando comparado aos grupos BIC e BPM. Não foram evidenciadas diferenças significativas quanto à sedação entre os grupos BIC e BPM. O custo financeiro do grupo MP foi sensivelmente menor quando comparado aos grupos BIC e BPM. A necessidade adicional de morfina foi significativamente maior no grupo MP, quando comparados aos grupos BIC e BPM.

Estimativa do Consumo Voluntário do Capim-Tanzânia (Panicum maximum, Jacq. cv. Tanzânia) por Vacas em Lactação sob Pastejo Rotacionado

O estudo foi conduzido numa área de capim-Tanzânia (Panicum maximum), manejada em pastejo rotacionado para estimar o consumo de matéria seca de vacas em lactação. Os três tratamentos foram: vacas mestiças alimentadas com 3 kg de concentrado e vacas mestiças e Zebu (Gir) sem suplementação com concentrado. Observou-se uma quantidade de 7340,2 kg de matéria seca (MS) /ha de forragem disponível antes da ocupação e de 5.639,5 após o 3° dia de ocupação. O consumo de MS de capim-Tanzânia foi 8,26 ± 5,66, 11,01 ± 5,37 e 9,55 ± 2,31 kg de MS/vaca/dia ou 2,15%, 2,37% e 2,34% do peso vivo, respectivamente para as vacas suplementadas, cruzadas não suplementadas e vacas Zebu . A média da produção de leite foi maior para o grupo suplementado (11,98 kg/vaca/dia). A produção de leite observada para as vacas não suplementadas foi similar. Produção de leite de 6,53 foi obtida pelas vacas cruzadas não suplementadas e 5,46 por vaca/dia foi produzida pelas vacas Zebu.

Foraging Behavior of the Swarm-Founding Wasp, Polybia (Trichothorax) sericea (Hymenoptera, Vespidae): Prey Capture and Load Capacity

The main component of the protein diet of P. sericea was larvae of Lepidoptera (75.38%), with predominance of the following Families: Noctuidae (30.99%), Hesperiidae (19.01%); Pyralidae (19.01%) and Nymphalidae (11.98%). The average weight of the prey captured was 14.2 mg, a value equivalent to 24.7% of the average wasp weight. The average glucidic food load was 28.61 mg, corresponding to approximately half the wasp weight (49.64%). The weight of the load transported in the crop varied according to the food density, which, in turn, influenced the time spent in its collection (Pearson: n=64; r=0.64;p<0.05). Polybia sericea showed predatory interactions against Lepidopteran caterpillars, who are known to be agricultural pests. P. sericea has potential to be used in Integrated Pest Management.

Voluntary intake of Tanzania grass (Panicum maximum) under rotational grazing by lactating cows

The study was conducted at Nucleo de Pesquisas Zootecnicas Nordeste of the Instituto de Zootecnia, Ribeirao Preto, SP, in a rotational grazing area of Tanzania grass (Panicum maximum), to estimate the dry matter intake by lactanting cows. The estimation of dry matter intake was calculated from the feces production estimated using extrusa Chromium-mordent and the in vitro digestibility of diet. The three treatments were crossbreed cows fed 3 kg.day(-1) of concentrate, crossbred cows without concentrate suplementation and pure Gir cows also without concentrate supplementation. The milk production was 11.98, 6.53 and 5.46 kg per cow per day, the grass intake was 8.26 +/- 5.66, 11.01 +/- 5.37 and 9.55 +/- 2.31 kg of dry matter per day or 2.15%, 2.37% and 2.34% of live weight for the three experimental groups respectively. The milk production was higher (P<0.01) for cows fed with concentrate. No difference was found for dry matter intake.

Cristo si è fermato a Eboli, de Carlo Levi e Francesco Rosi: memórias da cor de olhos tristes

As a hybrid genre, the narrative of Carlo Levi is an objective account and subjective elaboration that are equalized in a literary form. Written between 1943 and 1944, the book evokes with an atmosphere of memoir the period of 1935 and 1936, the writer’s exile. The film based on the narration fragmentizes the daily life of the problematic region and highlights the truth aimed by the discourses composed in times of crises, reinforced by action and expression without provincialism and also without a compensating aristocratic pose. It is possible to see some incapacity of the film by Rosi, natural to a certain degree, to translate the synthesis of literary treatment and socio-historical reflection. For this reason it is necessary to read the adaptation as an attitude about the literary matter and the result of historical experience. The memoir character relies on the artifice that makes good use of the book’s opening, the author’s short monologue, its narrative frame. The presence of paintings materializes the questions about the absurd contained in them

Distress related to myocardial infarction and cardiovascular outcome: a retrospective observational study

Background During acute coronary syndromes patients perceive intense distress. We hypothesized that retrospective ratings of patients' MI-related fear of dying, helplessness, or pain, all assessed within the first year post-MI, are associated with poor cardiovascular outcome. Methods We studied 304 patients (61 ± 11 years, 85% men) who after a median of 52 days (range 12-365 days) after index MI retrospectively rated the level of distress in the form of fear of dying, helplessness, or pain they had perceived at the time of MI on a numeric scale ranging from 0 ("no distress") to 10 ("extreme distress"). Non-fatal hospital readmissions due to cardiovascular disease (CVD) related events (i.e., recurrent MI, elective and non-elective stent implantation, bypass surgery, pacemaker implantation, cerebrovascular incidents) were assessed at follow-up. The relative CVD event risk was computed for a (clinically meaningful) 2-point increase of distress using Cox proportional hazard models. Results During a median follow-up of 32 months (range 16-45), 45 patients (14.8%) experienced a CVD-related event requiring hospital readmission. Greater fear of dying (HR 1.21, 95% CI 1.03-1.43), helplessness (HR 1.22, 95% CI 1.04-1.44), or pain (HR 1.27, 95% CI 1.02-1.58) were significantly associated with an increased CVD risk without adjustment for covariates. A similarly increased relative risk emerged in patients with an unscheduled CVD-related hospital readmission, i.e., when excluding patients with elective stenting (fear of dying: HR 1.26, 95% CI 1.05-1.51; helplessness: 1.26, 95% CI 1.05-1.52; pain: HR 1.30, 95% CI 1.01-1.66). In the fully-adjusted models controlling for age, the number of diseased coronary vessels, hypertension, and smoking, HRs were 1.24 (95% CI 1.04-1.46) for fear of dying, 1.26 (95% CI 1.06-1.50) for helplessness, and 1.26 (95% CI 1.01-1.57) for pain. Conclusions Retrospectively perceived MI-related distress in the form of fear of dying, helplessness, or pain was associated with non-fatal cardiovascular outcome independent of other important prognostic factors.

Improved antiretroviral treatment outcome in a rural African setting is associated with cART initiation at higher CD4 cell counts and better general health condition

Background Data on combination antiretroviral therapy (cART) in remote rural African regions is increasing. Methods We assessed prospectively initial cART in HIV-infected adults treated from 2005 to 2008 at St. Francis Designated District Hospital, Ifakara, Tanzania. Adherence was assisted by personal adherence supporters. We estimated risk factors of death or loss to follow-up by Cox regression during the first 12 months of cART. Results Overall, 1,463 individuals initiated cART, which was nevirapine-based in 84.6%. The median age was 40 years (IQR 34-47), 35.4% were males, 7.6% had proven tuberculosis. Median CD4 cell count was 131 cells/μl and 24.8% had WHO stage 4. Median CD4 cell count increased by 61 and 130 cells/μl after 6 and 12 months, respectively. 215 (14.7%) patients modified their treatment, mostly due to toxicity (56%), in particular polyneuropathy and anemia. Overall, 129 patients died (8.8%) and 189 (12.9%) were lost to follow-up. In a multivariate analysis, low CD4 cells at starting cART were associated with poorer survival and loss to follow-up (HR 1.77, 95% CI 1.15-2.75, p = 0.009; for CD4 <50 compared to >100 cells/μl). Higher weight was strongly associated with better survival (HR 0.63, 95% CI 0.51-0.76, p < 0.001 per 10 kg increase). Conclusions cART initiation at higher CD4 cell counts and better general health condition reduces HIV related mortality in a rural African setting. Efforts must be made to promote earlier HIV diagnosis to start cART timely. More research is needed to evaluate effective strategies to follow cART at a peripheral level with limited technical possibilities.

In silico target fishing for rationalized ligand discovery exemplified on constituents of Ruta graveolens

The identification of targets whose interaction is likely to result in the successful treatment of a disease is of growing interest for natural product scientists. In the current study we performed an exemplary application of a virtual parallel screening approach to identify potential targets for 16 secondary metabolites isolated and identified from the aerial parts of the medicinal plant RUTA GRAVEOLENS L. Low energy conformers of the isolated constituents were simultaneously screened against a set of 2208 pharmacophore models generated in-house for the IN SILICO prediction of putative biological targets, i. e., target fishing. Based on the predicted ligand-target interactions, we focused on three biological targets, namely acetylcholinesterase (AChE), the human rhinovirus (HRV) coat protein and the cannabinoid receptor type-2 (CB (2)). For a critical evaluation of the applied parallel screening approach, virtual hits and non-hits were assayed on the respective targets. For AChE the highest scoring virtual hit, arborinine, showed the best inhibitory IN VITRO activity on AChE (IC (50) 34.7 muM). Determination of the anti-HRV-2 effect revealed 6,7,8-trimethoxycoumarin and arborinine to be the most active antiviral constituents with IC (50) values of 11.98 muM and 3.19 muM, respectively. Of these, arborinine was predicted virtually. Of all the molecules subjected to parallel screening, one virtual CB (2) ligand was obtained, i. e., rutamarin. Interestingly, in experimental studies only this compound showed a selective activity to the CB (2) receptor ( Ki of 7.4 muM) by using a radioligand displacement assay. The applied parallel screening paradigm with constituents of R. GRAVEOLENS on three different proteins has shown promise as an IN SILICO tool for rational target fishing and pharmacological profiling of extracts and single chemical entities in natural product research.
