Elementos decorativos quinhentistas no convento dos Capuchos (Parques de Sintra - Monte da Lua)

Reaberto ao público em 2001 o convento dos Capuchos encontra-se num avançado estado de deterioração, nomeadamente ao nível dos revestimentos. Neste sentido foi possível identificar, sob pinturas murais do Séc. XVIII, a existência de uma cor negra que revestiria – barramento - a generalidade dos espaços interiores. No âmbito do diagnóstico de conservação conduzido pela empresa In-Situ a pedido da Parques de Sintra-Monte da Lua foram recolhidas amostras de materiais de revestimento e decoração quinhentista do convento (argamassas, barramentos, embrechados e embutido), com vista à sua caracterização.

Neuronal ceroid-lipofuscinosis, a type of amaurotic family idiocy: clinical and pathological study of four cases

Neuronal ceroid-lipofuscinosis (NCL) is a recent term, proposed for acurate designation of the late-onset types of Amaurotic Family Idiocy (AFI). Histopathology shows ubiquitous intraneuronal accumulation of lipopigments, being the most important factor for characterization of the entity at present time. Biochemical changes and pathogenesis are obscure. NCL is in contrast to the infantile type of AFI (Tay-Sachs disease), in which intraneuronal accumulation of gangliosides (sphingolipids) is due to the well known deficiency of a lysosomal enzyme. The authors report on four cases of NCL, two brothers of the late infantile (Jansky-Bielschowsky) type and a brother and a sister of the juvenile (Spielmeyer-Sjögren) type. One autopsy and three cortical biopsies revealed moderate to severe distention of the neurons by lipopigment, with nerve cell loss, gliosis and cerebral atrophy. Lipopigment was also increased in liver, heart and spleen. The patients were the first in Brazilian literature in whom the storage material was identified as lipopigment by histochemical methods. A brief summary of the clinical features of NCL is presented, and relevant problems are discussed, concerning interpretation of the nature of the storage material, and significance of the disease for gerontological research.

Machado de assis's epilepsy

Machado de Assis (1839-1908) is considered the most important Brazilian writer and a great universal literary figure. Little is know about his medical, personal and family history. He hid his «disease» as much as possible. Machado referred to «strange things» having happened to him in his childhood. He described seizures as «nervous phenomena», «absenses», «my illness». Laet observed a seizure and described it as: «... when Machado approached us and spoke to me in disconnected words. I looked at him in surprise and found his features altered. Knowing that from time to time he had nervous problems,... and only permitted Machado take the Laranjeiras Street car, when I saw that he was completely well». A photographically documented seizure is shown. Alencar wrote, «The preoccupation with health was frequent: either he was having the consequences of a fit or was foreboding one». It is clear that Machado presented localized symptomatic epilepsy with complex partial seizures secondarily generalized of unknown etiology. The seizures which began in infancy or childhood had remission in adolescence and then recurred in his thirties and became more frequent in his later years. His depression got markedly worse with age. In our opinion, the greatest consequence of Machado's epilepsy, was his psychological suffering due to the prejudice of the times. Despite this Machado showed all his genius, which is still actual and universal.

Juvenile idiopathic arthritis with involvement of the temporomandibular joint: the role of image examinations

PURPOSE: Juvenile idiopathic arthritis (JIA) has unknown etiology, and the involvement of the temporomandibular joint (TMJ) is rare in the early phase of the disease. The present article describes the use of computed tomography (CT) and magnetic resonance (MRI) images for the diagnosis of affected TMJ in JIA. CASE DESCRIPTION: A 12-year-old, female, Caucasian patient, with systemic rheumathoid arthritis and involvement of multiple joints was referred to the Imaging Center for TMJ assessment. The patient reported TMJ pain and limited opening of the mouth. The helical CT examination of the TMJ region showed asymmetric mandibular condyles, erosion of the right condyle and osteophyte-like formation. The MRI examination showed erosion of the right mandibular condyle, osteophytes, displacement without reduction and disruption of the articular disc. CONCLUSION: The disorders of the TMJ as a consequence of JIA must be carefully assessed by modern imaging methods such as CT and MRI. CT is very useful for the evaluation of discrete bone changes, which are not identified by conventional radiographs in the early phase of JIA. MRI allows the evaluation of soft tissues, the identification of acute articular inflammation and the differentiation between pannus and synovial hypertrophy.

Doença de Kawasaki: experiência clínica em hospital universitário

OBJETIVO: A doença de Kawasaki é uma vasculite sistêmica aguda de etiologia desconhecida. Seu diagnóstico baseia-se em critérios clínicos. O objetivo deste estudo foi descrever os casos de pacientes com doença de Kawasaki internados no Hospital Universitário da Universidade de São Paulo entre janeiro/2000 e junho/2008. MÉTODOS: Dentre todos os pacientes internados na Enfermaria de Pediatria no período acima, foram selecionados aqueles cujo CID de alta foi doença de Kawasaki. Realizou-se estudo descritivo por meio da análise dos prontuários dessas crianças. RESULTADOS: Foram encontrados 18 casos. A média de internações foi de 2,1 casos/ano. A idade variou de três meses a nove anos. A proporção meninos:meninas foi 1:1,25. Receberam outros diagnósticos prévios 17 pacientes, sendo escarlatina em 2/3 dos casos. O tempo de febre antes do diagnóstico variou de cinco a 11 dias. Nove crianças apresentaram quatro sinais sugestivos de doença de Kawasaki; oito apresentaram cinco sinais e uma apresentou dois sinais, o que foi considerado doença de Kawasaki incompleta. Receberam gamaglobulina 15 crianças (entre o sexto e o décimo dias de evolução) e 11 (73%) ficaram afebris após infusão da medicação. Os demais tiveram febre até 24 horas após a administração. Todos os pacientes realizaram ecocardiograma e três apresentaram aneurisma leve da coronária. CONCLUSÕES: A doença de Kawasaki é habitualmente confundida com outras doenças, o que causa retardo no tratamento e aumento no risco de complicações cardíacas.

Encefalite no litoral paulista: a emergência da epidemia e a reação da mídia impressa

No litoral sul do estado de São Paulo, ocorreu uma epidemia de encefalite pelo arbovírus Rocio de 1975 a 1978. As altas taxas de morbidade e mortalidade causaram impacto social. Neste trabalho, o objetivo foi apresentar um estudo sobre como a mídia impressa relatou os acontecimentos sociais relacionados ao surgimento da epidemia no primeiro semestre de 1975. Reportagens sobre a epidemia no litoral sul foram obtidas do banco de dados dos jornais A Tribuna, Folha de S.Paulo e Jornal da Tarde. Foram analisadas as notícias até o mês de julho de 1975, fase inicial e de maior impacto da epidemia. Com a identificação de casos de encefalite, de causa desconhecida, a Secretaria de Estado da Saúde desaconselhou a ida de turistas para o litoral, utilizando a mídia como veículo de divulgação. Diante das notícias, ocorreu a fuga dos turistas e, consequentemente, a crise do comércio. Observou-se a revolta dos comerciantes, que geraram embates contra a mídia, no que tange à forma de divulgação da epidemia. Alguns prefeitos alegaram inveracidade de notícias publicadas. A proibição feita pelas autoridades sanitárias foi relatada pela mídia de forma abrangente, englobando sujeitos envolvidos nesse discurso. Assim, foram reveladas ao público as tensões geradas entre os detentores do conhecimento científico e o poder econômico local. Os jornais realizaram cobertura abrangente, abordando vários temas, entretanto disseminaram incertezas e fizeram uso de imagens sensacionalistas, além de desarticular acontecimentos biológicos e sociais. Os temas chegaram aos leitores de forma fragmentada e com sentidos sociais comprometidos.

What are the similarities between stress, sudden cardiac death in Gallus gallus and sudden unexpected death in people with epilepsy

Individuals with epilepsy are at higher risk of sudden unexpected death in epilepsy (SUDEP), responsible for 7.5% to 17% of all deaths in epilepsy. Many factors are current associated with SUDEP and possible effect of stress and cardiac arrhythmia are still not clear. Sudden death syndrome (SDS) in chickens is a disease characterized by an acute death of well-nourished and seeming healthy Gallus gallus after abrupt and brief flapping of their wings, similar to an epileptic seizure, with an incidence estimated as 0.5 to 5% in broiler chickens. A variety of nutritional and environmental factors have been included: but the exactly etiology of SDS is unknown. Studies had suggested that the hearts of broiler chickens are considerably more susceptible to arrhythmias and stress may induce ventricular arrhythmia and thus, sudden cardiac death. In this way, SDS in Gallus gallus could be an interesting model to study SUDEP.

Trabalho e imigração: uma comparação Brasil-Argentina

O artigo busca discutir um novo padrão migratório da Bolívia para o Brasil e para a Argentina, especialmente vinculado à precarização do trabalho e à inserção desses imigrantes em formas de trabalho precário. Esse padrão & aparentemente novo em relação à integração dos contingentes migrantes ao longo do século XX & vem produzindo consequências que ainda estão por ser mapeadas. Uma delas é a presença de um contingente de bolivianos confinado ao setor de costura, trabalhando e vivendo em oficinas clandestinas, com pouca visibilidade pública, como face de uma precarização mundializada, resultante do assim chamado “custo chinês”. Resultante de um balanço bibliográfico e de uma incursão exploratória na pesquisa de campo tanto em São Paulo como em Buenos Aires, o artigo pretende apontar para aspectos específicos do fenômeno, combinando olhares e perspectivas que cruzam as dimensões migratórias, geracionais e de gênero.

Phenotypic and genotypic analysis of Helicoverpa armigera nucleopolyhedrovirus serially passaged in cell culture

Rapid accumulation of few polyhedra (FP) mutants was detected during serial passaging of Helicoverpa armigera nucleopolyhedrovirus (HaSNPV) in cell culture. 100% FP infected cells were observed by passage 6. The specific yield decreased from 178 polyhedra per cell at passage 2 to two polyhedra per cell at passage 6. The polyhedra at passage 6 were not biologically active, with a 28-fold reduction in potency compared to passage 3. Electron microscopy studies revealed that very few polyhedra were produced in an FP infected cell (< 10 polyhedra per section) and in most cases these polyhedra contained no virions. A specific failure in the intranuclear nucleocapsid envelopment process in the FP infected cells, leading to the accumulation of naked nucleocapsids, was observed. Genomic restriction endonuclease digestion profiles of budded virus DNA from all passages did not indicate any large DNA insertions or deletions that are often associated with such FP phenotypes for the extensively studied Autographa californica nucleopolyhedrovirus and Gaileria mellonella nucleopolyhedrovirus. Within an HaSNPV 25K FP gene homologue, a single base-pair insertion (an adenine residue) within a region of repetitive sequences (seven adenine residues) was identified in one plaque-purified HaSNPV FP mutant. Furthermore, the sequences obtained from individual clones of the 25KFP gene PCR products of a late passage revealed point mutations or single base-pair insertions occurring throughout the gene. The mechanism of FP mutation in HaSNPV is likely similar to that seen for Lymantria dispar nucleopolyhedrovirus, involving point mutations or small insertions/deletions of the 25K FP gene.

Sensitivity of Helicoverpa armigera nucleopolyhedrovirus polyhedra to sodium dodecyl sulfate

Sodium dodecyl sulfate (SDS) is commonly used to extract polyhedra from infected cells and diseased dead larval tissues. It was found, however, that 80% of Helicoverpa armigera nucleopolyhedrovirus (HaSNPV) polyhedra produced via cell culture were damaged after 30 min of 0.5% SDS treatment whereas only 20% of in vivo produced polyhedra were damaged by the same treatment. Transmission and scanning electron microscopy revealed that the damaged polyhedra had lost their polyhedron envelopes and virions were dislodged from the polyhedrin matrix, leaving empty spaces that were previously occupied by the occluded virions. Up to 20% in vitro produced polyhedra were resistant to SDS and remained intact, even after a 24 h exposure to SDS. This sensitivity to SDS was observed across a range of cell culture media, including serum supplemented media. Electron microscopy also revealed that the inferior polyhedron envelope of in vitro produced polyhedra is likely due to poor interaction between the polyhedron envelope, polyhedron envelope protein (PEP), and polyhedrin matrix. The PEP gene was cloned and sequenced and mutations in this gene were ruled out as an explanation. In vitro produced polyhedra that were passed through insect larva once were resistant to SDS, indicating that a critical component is lacking in insect cell culture medium used for producing HaSNPV or the cells growing in culture are inefficient in some ways in relation to production of polyhedra.

Effect of time of harvest of budded virus on the selection of baculovirus FP mutants in cell culture

Rapid formation and selection of FP (few polyhedra) mutants occurs during serial passaging of Helicoverpa armigera nucleopolyhedrovirus (HaSNPV) in insect cell culture. The production of HaSNPV for use as biopesticides requires the passaging of the virus over a number of passages to produce enough virus inoculum for large-scale fermentation. During serial passaging in cell culture, FP mutants were rapidly selected, resulting in declined productivity and reduced potency of virus. Budded virus (BV) is usually harvested between 72 and 96 h postinfection (hpi) in order to obtain a high titer virus stock. In this study, the effect of tine of harvest (TOH) for BV on the selection rate of HaSNPV FP mutants during serial passaging was investigated. BV were harvested at different times postinfection, and each series was serially passaged for six passages. The productivity and percentage of FP mutants at each passage were determined. It was found that the selection of FP mutants can he reduced by employing an earlier TOH for BV. Serial passaging with BV harvested at 48 hpi showed a slower accumulation of FP mutants compared to that of BV harvested after 48 hpi. Higher cell specific yields were also maintained when BV were harvested at 48 hpi. When BV that were formed between 48 and 96 hpi were harvested and serially passaged, FP mutants quickly dominated the virus population. This suggests that the V formed and released between 48 and 96 hpi are most likely from FP mutant infected cells.
