Desafios da arte contemporânea à conservação e restauro. Documentar a arte Portuguesa dos anos 60/70

A dissertação que aqui se apresenta partiu da necessidade de colocar em confronto as bases éticas da conservação e restauro, que assentam na defesa da materialidade histórica, com a progressiva desmaterialização da arte que ocorre a partir da década de 60 em diante. A organização do trabalho implicou, na escrita, a distinção entre duas partes: uma históricoteórica e a outra de carácter mais prático. Na primeira parte procurámos justificar a progressiva tendência histórica para a desmaterialização do suporte artístico bem como a consequente necessidade de um re-pensamento dos aspectos éticos e práticos da conservação, com particular atenção à documentação do ponto de vista autoral. Na segunda parte da dissertação apresentamos um conjunto de oito casos práticos, a partir de obras de oito artistas portugueses – Henrique Ruivo, Lourdes Castro, Noronha da Costa, Ana Vieira, Alberto Carneiro, João Vieira, René Bertholo e Helena Almeida - todos com início de carreira na década de 60. Procurámos reunir, com base numa investigação em torno dos aspectos da criação da obra, mas também da sua recepção, informação detalhada sobre materiais constitutivos, sua origem e semântica, técnicas, processos criativos, bem como a posição de cada autor relativamente ao envelhecimento das obras em análise. Para o efeito procedemos a um conjunto de entrevistas presenciais aos artistas em questão, directores de museus e curadores – com envolvimento com as obras daqueles - bem como ao levantamento da fortuna crítica associada às obras seleccionadas. Um dos aspectos que se revelou decisivo ao longo do trabalho foi o da investigação dos processos criativos, central para obras cuja autenticidade não se pode resumir a qualquer noção de originalidade material, podendo contudo ser alicerçada na investigação e documentação do processo criativo, realizado essencialmente a partir do ponto de vista autoral. O trabalho efectuado teve também como objectivo a compreensão das condições reais de conservação documental das peças. Concluímos: a necessidade de se proceder à documentação(inscrição) como forma de conservação; o papel imprescindível de uma historiografia da arte mais centrada nos aspectos da preservação; a urgência de formar profissionais preparados para desempenhar esta tarefa; bem como a indispensabilidade de ferramentas que permitam a organização da informação e a sua disponibilização, no âmbito da comunidade envolvida na arte contemporânea, e ao público em geral.

Enhanced expression of 70-kilodalton heat shock protein limits cell division in a sepsis-induced model of acute respiratory distress syndrome.

OBJECTIVE: Fibrotic changes are initiated early in acute respiratory distress syndrome. This may involve overproliferation of alveolar type II cells. In an animal model of acute respiratory distress syndrome, we have shown that the administration of an adenoviral vector overexpressing the 70-kd heat shock protein (AdHSP) limited pathophysiological changes. We hypothesized that this improvement may be modulated, in part, by an early AdHSP-induced attenuation of alveolar type II cell proliferation. DESIGN: Laboratory investigation. SETTING: Hadassah-Hebrew University and University of Pennsylvania animal laboratories. SUBJECTS: Sprague-Dawley Rats (250 g). INTERVENTIONS: Lung injury was induced in male Sprague-Dawley rats via cecal ligation and double puncture. At the time of cecal ligation and double puncture, we injected phosphate-buffered saline, AdHSP, or AdGFP (an adenoviral vector expressing the marker green fluorescent protein) into the trachea. Rats then received subcutaneous bromodeoxyuridine. In separate experiments, A549 cells were incubated with medium, AdHSP, or AdGFP. Some cells were also stimulated with tumor necrosis factor-alpha. After 48 hrs, cytosolic and nuclear proteins from rat lungs or cell cultures were isolated. These were subjected to immunoblotting, immunoprecipitation, electrophoretic mobility shift assay, fluorescent immunohistochemistry, and Northern blot analysis. MEASUREMENTS AND MAIN RESULTS: Alveolar type I cells were lost within 48 hrs of inducing acute respiratory distress syndrome. This was accompanied by alveolar type II cell proliferation. Treatment with AdHSP preserved alveolar type I cells and limited alveolar type II cell proliferation. Heat shock protein 70 prevented overexuberant cell division, in part, by inhibiting hyperphosphorylation of the regulatory retinoblastoma protein. This prevented retinoblastoma protein ubiquitination and degradation and, thus, stabilized the interaction of retinoblastoma protein with E2F1, a key cell division transcription factor. CONCLUSIONS: : Heat shock protein 70-induced attenuation of cell proliferation may be a useful strategy for limiting lung injury when treating acute respiratory distress syndrome if consistent in later time points.

The role of daytime napping in sleepiness and cognitive function in 24-70 year olds /

Daytime napping improves well-being and performance for young adults. The benefits of napping in older adults should be investigated because they have fragmented nocturnal sleep, cognitive declines, and more opportunity to nap. In addition, experience with napping might influence the benefits of napping. Study 1 examined the role of experience with napping in young adults. Habitual (n = 23) and non-habitual nappers (n = 16) were randomly assigned to a 20-minute nap or a 20- minute reading condition. Both groups slept the same according to macro architecture. However, microarchitecture showed greater theta, alpha, and beta power during Stage 1, and greater delta, alpha, and sigma power during Stage 2 for habitual nappers, for the most part indicating better sleep. Both groups felt less sleepy after the nap. P2 latency, reflecting information processing, decreased after the nap for habitual nappers, and after the control condition for non-habitual nappers. In sum, both groups who slept felt better, but only the habitual nappers who napped gained a benefit in terms of information processing. Based on this outcome, experience with napping was investigated in Study 2. Study 2 examined the extent to which daytime napping enhanced cognition in older adults, especially frontal lobe function. Cognitive deficits in older adults may be due to sleep loss and age-related decline in brain functioning. Longer naps were expected to provide greater improvement, particularly for older adults, by reducing sleep pressure. Thirty-two adults, aged 24-70 years, participated in a repeated measures dose-response manipulation of sleep pressure. Twenty- and sixty-minute naps were compared to a no-nap condition in three age groups. Mood, subjective sleepiness, reaction time, working memory, 11 novelty detection, and waking electro physiological measures were taken before and after each condition. EEG was also recorded during each nap or rest condition. Napping reduced subjective sleepiness, improved working memory (serial addition / subtraction task), and improved attention (reduced P2 amplitude). Physiological sleepiness (i.e., waking theta power) increased following the control condition, and decreased after the longer nap. Increased beta power after the short nap, and seen with older adults overall, may have reflected increased mental effort. Older adults had longer latencies and smaller amplitudes for several event-related potential components, and higher beta and gamma power. Following the longer nap, gamma power decreased for older adults, but increased for young adults. Beta and gamma power may represent enhanced alertness or mental effort. In addition, Nl amplitude showed that benefits depend on the preceding nap length as well as age. Since the middle group had smaller Nl amplitudes following the short nap and rest condition, it is possible that they needed a longer nap to maintain alertness. Older adults did not show improvements to Nl amplitude following any condition; they may have needed a nap longer than 60 minutes to gain benefits to attention or early information processing. Sleep characteristics were not related to benefits of napping. Experience with napping was also investigated. Subjective data confirmed habitual nappers were happier to nap, while non-habitual nappers were happier to stay awake, reflecting self-identified napping habits. Non-habitual nappers were sleepier after a nap, and had faster brain activity (i.e., heightened vigilance) at sleep onset. These reasons may explain why non-habitual nappers choose not to nap.
