Effect of alcohol on iron storage diseases of the liver

The consumption of excess alcohol in patients with liver iron storage diseases, in particular the iron-overload disease hereditary haemochromatosis (HH), has important clinical consequences. HH, a common genetic disorder amongst people of European descent, results in a slow, progressive accumulation of excess hepatic iron. If left untreated, the condition may lead to fibrosis, cirrhosis and primary hepatocellular carcinoma. The consumption of excess alcohol remains an important cause of hepatic cirrhosis and alcohol consumption itself may lead to altered iron homeostasis. Both alcohol and iron independently have been shown to result in increased oxidative stress causing lipid peroxidation and tissue damage. Therefore, the added effects of both toxins may exacerbate the pathogenesis of disease and impose an increased risk of cirrhosis. This review discusses the concomitant effects of alcohol and iron on the pathogenesis of liver disease. We also discuss the implications of co-existent alcohol and iron in end-stage liver disease.

Effect of storage time and conditions on the seed coat colour of Australian adzuki beans

Two varieties of adzuki beans (Vigna angularis), Bloodwood and Erimo, were stored at temperatures of 10, 20 or 30degreesC, and relative humidities (RH) 40 or 65%, and samples were analysed at 0, 1.5, 3 and 6 months. Storage at 30degreesC for > 1.5 months caused a significant decrease in the a(star) and b(star) colour values and darkening of the seed coat. Beans stored at 65% RH had lower L-star but higher a(star) and b(star) colour values than those stored at 40% RH. Bloodwood and Erimo samples showed similar trends in colour during storage. The best storage conditions for the preservation of the adzuki colour were 10degreesC and 65% RH. The Australian beans had lower L-star, a(star) and b(star) colour values than Japanese Erimo-shouzu beans and storage increased the difference.

Effect of storage time and conditions on the cotyledon cell wall of the adzuki bean (Vigna angularis)

Two varieties of adzuki grown in Australia, Bloodwood and Erimo, were stored for up to 6 months at three temperatures (10, 20 and 30 degreesC), and two relative humidities (RH; 40 and 65%). The amount of cell wall material increased with time under all storage conditions. This increase was greatest at 30 degreesC and 40% RH. Storage time and conditions did not affect the total pectin levels in the cell wall. Erimo constantly exhibited a higher total pectin level than Bloodwood. The Bloodwood soluble pectin, Ca++ and Mg++ and Erimo Ca++ in the cell wall remained stable during storage, while the Erimo soluble pectin and Mg++ exhibited a slight decrease at 20 and 30 degreesC after 3 months of storage.

Complicações perinatais no Hospital Universitário Cassiano Antonio de Moraes: uma questão de idade?

A população brasileira vem passando por uma transição demográfica e epidemiológica, caracterizadas por aumento na expectativa de vida, diminuições nas taxas de mortalidade, natalidade e fecundidade, aumento da escolaridade, diminuição do desemprego, aumento das enfermidades crônico-degenerativas e diminuição das enfermidades infectocontagiosas. Tais transições vêm afetando também a perinatologia, com aumento proporcional e absoluto das gestações tardias tanto no Espírito Santo quanto no Brasil. Este estudo realizou uma análise retrospectiva das gestações tardias no HUCAM, comparando as mesmas com as gestações de mulheres adolescentes e adultas jovens quanto aos seguintes desfechos perinatais: anomalia fetal, hipóxia no primeiro e quinto minuto de vida, duração da gestação, peso ao nascer e tipo de parto. As variáveis foram analisadas categoricamente, e comparadas através de análise bivariada, utilizando-se o Teste Exato de Fisher, e através de regressão logística. Na análise bivariada, foi encontrada apenas associação entre a idade materna e o tipo de parto, mas esta associação não foi confirmada na regressão logística. Analisando outros fatores relativos à gestação, restou evidenciado uma associação positiva entre um menor número de consultas pré-natais e uma maior frequência de hipóxia no recém-nascido e de prematuridade (odds ratio de 2,9 e 5,7, respectivamente). Ao final deste trabalho são elaboradas propostas para aprimoramento da coleta e do armazenamento de dados acerca da gestação no HUCAM, e para otimização da assistência pré-natal das gestantes atendidas pelo hospital, visando melhorar os desfechos perinatais encontrados.

Efeito da adição de extrato de casca de jabuticaba nas características físico-químicas e sensoriais de queijo petit suisse

A busca pela melhoria da qualidade de vida e a procura por alimentos naturais e funcionais são crescentes. A incorporação de prebióticos e corantes naturais pode agregar valor ao produto, por serem capazes de melhorar sua qualidade e por apresentarem grandes atrativos tecnológicos. Portanto, o objetivo deste trabalho foi avaliar o efeito da adição de prebióticos (inulina e oligofrutose) e corante natural (extrato de casca de jabuticaba) nas características de queijo petit suisse. Foi realizada análise da composição físico-química (extrato seco total, cinzas, proteínas, lipídeos, carboidratos e acidez titulável) logo após o processamento, análise do pH, colorimetria, teor de compostos bioativos e atividade antioxidante em diferentes tempos de armazenamento (0, 7, 14, 21 e 28 dias), análise do teor de fibras alimentares da formulação de queijo petit suisse com maior atividade antioxidante ao final da vida de prateleira e análises microbiológica e sensorial. O queijo petit suisse elaborado foi dividido em cinco formulações, de acordo com a concentração de corante natural incorporado, que foram 0%, 1,5%, 2,0%, 2,5% e 3,0%. Os dados obtidos com as análises realizadas logo após o processamento e análise sensorial foram submetidos à análise de variância e teste de Tukey, os dados obtidos com as análises realizadas em diferentes tempos de armazenamento foram submetidos à análise de variância e estudo do comportamento cinético, e a análise de fibras e microbiológica foi analisada por meio de estatística descritiva. Os valores de extrato seco total, proteínas, lipídeos, cinzas e carboidrato não diferiram significativamente (p>0,05) entre as formulações. A formulação sem adição de corante natural apresentou menor acidez (p≤0,05), e com o aumento da concentração de corante natural, maior foi a acidez do queijo. Os teores de antocianinas, fenólicos totais e capacidade antioxidante foram maiores com o aumento da concentração de corante incorporado, sendo que o teor de antocianinas reduziu com o decorrer do tempo de armazenamento. O valor encontrado de fibras para a formulação contendo 3,0% de corante natural foi baixo, e o produto não apresentou alegação de propriedade funcional. A fim de verificar se o queijo estava próprio para o consumo, foi realizada análise microbiológica para coliformes termotolerantes, estando todas as formulações de queijo petit suisse em condições sanitárias satisfatórias. A análise sensorial foi realizada em duas etapas. Na primeira etapa foi realizado teste de aceitação com avaliação dos atributos cor, sabor, consistência e impressão global, e intenção de compra para todas as formulações com incorporação de corante natural. Na segunda etapa foi realizado o teste de aceitação com informação nutricional do produto para a amostra mais aceita na primeira etapa. Como resultado, foi observado que o atributo cor foi o único que apresentou diferença significativa (p≤0,05) entre as formulações, sendo as mais aceitas com concentração 2,5% e 3,0%. De forma geral, todas as formulações foram bem aceitas, porém, a formulação com maior adição de corante natural foi a que xiii apresentou maiores notas. Assim, o queijo com maior concentração de corante natural foi o utilizado na segunda etapa sensorial, sendo observada influência das informações nos atributos cor e consistência (p≤0,05). Dessa forma, a utilização de prebióticos e corante natural de casca de jabuticaba em queijo petit suisse foi viável por não alterar a composição centesimal do produto, além de conferir ao produto uma coloração atrativa.

Privacy and Data Protection in Elderly Healthcare: Threats and Legal Warranties

The progressive aging of the population requires new kinds of social and medical intervention and the availability of different services provided to the elder population. New applications have been developed and some services are now provided at home, allowing the older people to stay home instead of having to stay in hospitals. But an adequate response to the needs of the users will imply a high percentage of use of personal data and information, including the building up and maintenance of user profiles, feeding the systems with the data and information needed for a proactive intervention in scheduling of events in which the user may be involved. Fundamental Rights may be at stake, so a legal analysis must also be considered.

The need for standardized tests to evaluate the reliability of data transport in wireless medical systems

Wireless medical systems are comprised of four stages, namely the medical device, the data transport, the data collection and the data evaluation stages. Whereas the performance of the first stage is highly regulated, the others are not. This paper concentrates on the data transport stage and argues that it is necessary to establish standardized tests to be used by medical device manufacturers to provide comparable results concerning the communication performance of the wireless networks used to transport medical data. Besides, it suggests test parameters and procedures to be used to produce comparable communication performance results.

A brief survey on online analysis of movement data

The increasing availability of mobility data and the awareness of its importance and value have been motivating many researchers to the development of models and tools for analyzing movement data. This paper presents a brief survey of significant research works about modeling, processing and visualization of data about moving objects. We identified some key research fields that will provide better features for online analysis of movement data. As result of the literature review, we suggest a generic multi-layer architecture for the development of an online analysis processing software tool, which will be used for the definition of the future work of our team.

COORDINSPECTOR: a tool for extracting coordination data from legacy code

More and more current software systems rely on non trivial coordination logic for combining autonomous services typically running on different platforms and often owned by different organizations. Often, however, coordination data is deeply entangled in the code and, therefore, difficult to isolate and analyse separately. COORDINSPECTOR is a software tool which combines slicing and program analysis techniques to isolate all coordination elements from the source code of an existing application. Such a reverse engineering process provides a clear view of the actually invoked services as well as of the orchestration patterns which bind them together. The tool analyses Common Intermediate Language (CIL) code, the native language of Microsoft .Net Framework. Therefore, the scope of application of COORDINSPECTOR is quite large: potentially any piece of code developed in any of the programming languages which compiles to the .Net Framework. The tool generates graphical representations of the coordination layer together and identifies the underlying business process orchestrations, rendering them as Orc specifications

Criminal Liability of Organizations, Corporations, Legal Persons, and Similar Entities on Law of Portuguese Cybercrime: A Brief Discussion on the Issue of Crimes of “False Information,” the “Damage on Other Programs or Computer Data,” the “Computer-Software Sabotage,” the “Illegitimate Access,” the “Unlawful Interception,” and “Illegitimate Reproduction of the Protected Program”

Abstract: in Portugal, and in much of the legal systems of Europe, «legal persons» are likely to be criminally responsibilities also for cybercrimes. Like for example the following crimes: «false information»; «damage on other programs or computer data»; «computer-software sabotage»; «illegitimate access»; «unlawful interception» and «illegitimate reproduction of protected program». However, in Portugal, have many exceptions. Exceptions to the «question of criminal liability» of «legal persons». Some «legal persons» can not be blamed for cybercrime. The legislature did not leave! These «legal persons» are v.g. the following («public entities»): legal persons under public law, which include the public business entities; entities utilities, regardless of ownership; or other legal persons exercising public powers. In other words, and again as an example, a Portuguese public university or a private concessionaire of a public service in Portugal, can not commit (in Portugal) any one of cybercrime pointed. Fair? Unfair. All laws should provide that all legal persons can commit cybercrimes. PS: resumo do artigo em inglês.

An interactive state monad example

A common problem among information systems is the storage and maintenance of permanent information identified by a key. Such systems are typically known as data base engines or simply as data bases. Today the systems information market is full of solutions that provide mass storage capacities implemented in different operating system and with great amounts of extra functionalities. In this paper we will focus on the formal high level specification of data base systems in the Haskell language. We begin by introducing a high level view of a data base system with a specification of the most common operations in a functional point of view. We then augment this specification by lifting to the state monad which is then modified once again to permit input/output operations between the computations

Real-time 3D interactive segmentation of echocardiographic data through user-based deformation of B-spline explicit active surfaces

Image segmentation is an ubiquitous task in medical image analysis, which is required to estimate morphological or functional properties of given anatomical targets. While automatic processing is highly desirable, image segmentation remains to date a supervised process in daily clinical practice. Indeed, challenging data often requires user interaction to capture the required level of anatomical detail. To optimize the analysis of 3D images, the user should be able to efficiently interact with the result of any segmentation algorithm to correct any possible disagreement. Building on a previously developed real-time 3D segmentation algorithm, we propose in the present work an extension towards an interactive application where user information can be used online to steer the segmentation result. This enables a synergistic collaboration between the operator and the underlying segmentation algorithm, thus contributing to higher segmentation accuracy, while keeping total analysis time competitive. To this end, we formalize the user interaction paradigm using a geometrical approach, where the user input is mapped to a non-cartesian space while this information is used to drive the boundary towards the position provided by the user. Additionally, we propose a shape regularization term which improves the interaction with the segmented surface, thereby making the interactive segmentation process less cumbersome. The resulting algorithm offers competitive performance both in terms of segmentation accuracy, as well as in terms of total analysis time. This contributes to a more efficient use of the existing segmentation tools in daily clinical practice. Furthermore, it compares favorably to state-of-the-art interactive segmentation software based on a 3D livewire-based algorithm.

Cold storage of peaches cv. Aurora grown in the Zona da Mata Mineira, Minas Gerais State, Brazil

This study aimed to evaluate the postharvest behavior of peach cv. Aurora 1 harvested in the Zona da Mata region of Minas Gerais in two ripening stages and kept under different storage temperatures. Fruits on mid-ripe and fully ripe stages were stored at three temperatures: 5.6 ± 1.57 °C and 72.8 ± 3.8% RH; 10.4 ± 0.5 °C and 95.8 ± 5.5% RH; 21.04 ± 1.63 °C and 96.9 ± 2.6% RH up to 28 storage days (SD) . During storage, fruits stored at 21.04 ± 1.63 °C were evaluated every two days until 8 SD, and every four days for fruits stored at other temperatures. The harvest day was assigned as day zero. The variables evaluated were CO2 production, color of the pericarp and pulp, fresh mass loss, flesh firmness, total soluble solids, titratable acidity, contents of ascorbic acid and carotenoids. The fresh mass loss increased during storage, peaking at 5.6 °C. The reduction in ascorbic acid content was higher in fully ripe fruits at all temperatures. Mid-ripe fruits reached the end of the storage period with better quality. The temperature of 10.4 °C was the most efficient in keeping postharvest quality of peach cv. Aurora 1 harvested in the Zona da Mata region.
