After 4K, 8K UHD resolution can be considered the new challenge for film, visualization and television. Due to the dimension of 8K image, the remote micro and macro images are considered appropriate for visualization with scientific and educational purposes. This article describes the implementation of the 8K video plug-in to play UHD videos into the SAGE, a collaborative environment for the advancement of scientific research and education developed by EVL (Electronic Visualization Laboratory), upgrading its current resolution for video playing. It also presents the challenges of producing 8K content, the development of the code and introduces the features to view 8K ultra high definition videos in multiple tiles through the use of low cost computer clusters. The SAGE 8K video plug-in implementation was made possible because of the previous development of the Fogo Player, a system to run 4K and 8K content. The results were successfully presented at the CineGrid International Workshop 2013 in San Diego.

PLOS ONE , 2011, DOI: 10.1371/journal.pone.0024850
Abstract: Familial amyloidotic polyneuropathy (FAP) is a systemic conformational disease characterized by extracellular amyloid fibril formation from plasma transthyretin (TTR). This is a crippling, fatal disease for which liver transplantation is the only effective therapy. More than 80 TTR point mutations are associated with amyloidotic diseases and the most widely accepted disease model relates TTR tetramer instability with TTR point mutations. However, this model fails to explain two observations. First, native TTR also forms amyloid in systemic senile amyloidosis, a geriatric disease. Second, age at disease onset varies by decades for patients bearing the same mutation and some mutation carrier individuals are asymptomatic throughout their lives. Hence, mutations only accelerate the process and non-genetic factors must play a key role in the molecular mechanisms of disease. One of these factors is protein glycation, previously associated with conformational diseases like Alzheimer's and Parkinson's. The glycation hypothesis in FAP is supported by our previous discovery of methylglyoxal-derived glycation of amyloid fibrils in FAP patients. Here we show that plasma proteins are differentially glycated by methylglyoxal in FAP patients and that fibrinogen is the main glycation target. Moreover, we also found that fibrinogen interacts with TTR in plasma. Fibrinogen has chaperone activity which is compromised upon glycation by methylglyoxal. Hence, we propose that methylglyoxal glycation hampers the chaperone activity of fibrinogen, rendering TTR more prone to aggregation, amyloid formation and ultimately, disease.

Abstract: purpose: the aim of this study was to analyze the changes that occur in rats with experimental endometriosis after treatment with copaiba oil. methods: experimental endometriosis was induced in rats. the experimental group received copaiba oil (copaiferalangsdorffii) orally (0.63 mg/day), and the control group received a 0.9% sodium chloride solution orally (1 ml/100 g of body weight/day). both groups were treated with gavage for 14 days. after this period, the animals were euthanized, and the implant volume was calculated. the autologous transplants were removed, dyed with hematoxylin-eosin, and analyzed by light microscopy. results: the average final volumes were significantly different between the groups (p=0.007). there was a significant increase (p=0.012) between the initial and final volumes in the control group, whereas treatment with copaiferalangsdorffii caused a marked reduction in endometrial growth over time (p=0.016). histologically, 6/11 (55.00%) rats in the experimental group had a well-preserved epithelial layer, and 3 (45.00%) had mildly preserved epithelium. the control group had seven cases (58.30%) of well-preserved epithelial cells and five cases (41.70%) of mildly preserved epithelial cells (p>0.05). conclusion: copaiba oil (copaiferalangsdorffii) appears to be a promising alternative treatment for endometriosis.

Abstract: This study was carried out to determine the acute toxicity of the whole Cordia salicifolia extract (LD50) after oral and intraperitoneal administration in mice, and its effect on certainbiochemical parameters in the plasma of rats after 90 days of administration. The oral LD50 value of the extract was higher than 2000 mg/kg while the LD50 by intraperitoneal injections was about 920mg/kg. A daily oral administration of extracts at 20, 100, 200 and 400 mg/kg doses for 90 days did not cause significant changes in the body weight gain, organs weight or biochemical assays and hematology in the animals. The results showed that the administration of the extract for a prolonged period did not produce toxic effects in the animals. Este estudo foi realizado para determinar a toxicidade aguda do extrato total de Cordia salicifolia (DL50) após administra o oral e intraperitoneal em camundongos, assim como os efeitos do extrato sobre alguns parametros bioquímicos no plasma de ratos após um tratamento prolongado (90 dias). A DL50 do extrato administrado por v.o. foi maior que 2000 mg/Kg, enquanto a DL50 por via i.p. foi aproximadamente 920 mg/Kg. A administra o oral diária do extrato nas doses de 20, 100, 200 e 400 mg/kg por um período de 90 dias n o causou modifica es no ganho de peso corporal, no peso dos órg os, nosparametros hematológicos e bioquímicos dos animais. Estes resultados indicam que a administra o do extrato por um período mais prolongado n o provocou efeitos de toxicidade nos animais.

Abstract: O objetivo deste estudo foi verificar a resistência à remo o por tra o e a infiltra o marginal de coroas totais fundidas cimentadas com cimento de ion mero de vidro, em dentes reconstruídos com duas formula es de cimento de ion mero de vidro, ou seja, Cermet e "mistura milagrosa", em compara o às coroas totais cimentadas em dentes com preparo para coroa total (sem reconstru o). Foram selecionados trinta molares superiores recém-extraídos, dez para cada condi o experimental. Uma liga do sistema prata/estanho (M3) foi utilizada para obten o das coroas totais. As amostras foram submetidas a ciclagens térmicas nas temperaturas de 5oC, 37oC e 55oC, por sessenta minutos, durante sete dias. Para a última ciclagem térmica, foi utilizado o corante Rhodamina B a 0,1%, em solu o aquosa. A seguir, as amostras foram lavadas e mantidas em condi es ambientais por vinte e quatro horas, para serem levadas à máquina de ensaios universal, para os testes de remo o por tra o axial. A análise de variancia mostrou diferen a estatisticamente significante, no nível de 5%, dos dentes sem reconstru o (controle), com rela o aos dentes reconstruídos com "mistura milagrosa" e dentes reconstruídos com Cermet. Os dentes sem reconstru o apresentaram maior média aos testes de resistência por tra o. Verificou-se, pela compara o individual entre as condi es avaliadas, que o grupo reconstruído com "mistura milagrosa" e Cermet n o mostrou diferen a estatisticamente significante. Da mesma forma, foram elaboradas compara es individuais entre as condi es avaliadas dos escores de infiltra o, em que se p de observar que houve significancia entre os grupos de "mistura milagrosa" e Cermet com o grupo controle (dentes sem reconstru o). Os dentes reconstruídos com "mistura milagrosa" e Cermet n o mostraram diferen as estatisticamente significantes entre si
