Processing of metacaspase into a cytoplasmic catalytic domain mediating cell death in Leishmania major.

Metacaspases are cysteine peptidases that could play a role similar to caspases in the cell death programme of plants, fungi and protozoa. The human protozoan parasite Leishmania major expresses a single metacaspase (LmjMCA) harbouring a central domain with the catalytic dyad histidine and cysteine as found in caspases. In this study, we investigated the processing sites important for the maturation of LmjMCA catalytic domain, the cellular localization of LmjMCA polypeptides, and the functional role of the catalytic domain in the cell death pathway of Leishmania parasites. Although LmjMCA polypeptide precursor form harbours a functional mitochondrial localization signal (MLS), we determined that LmjMCA polypeptides are mainly localized in the cytoplasm. In stress conditions, LmjMCA precursor forms were extensively processed into soluble forms containing the catalytic domain. This domain was sufficient to enhance sensitivity of parasites to hydrogen peroxide by impairing the mitochondrion. These data provide experimental evidences of the importance of LmjMCA processing into an active catalytic domain and of its role in disrupting mitochondria, which could be relevant in the design of new drugs to fight leishmaniasis and likely other protozoan parasitic diseases.

Resilient housing : a new resource-oriented approach

The institutional regimes framework has previously been applied to the institutional conditions that support or hinder the sustainability of housing stocks. This resource-based approach identifies the actors across different sectors that have an interest in housing, how they use housing, the mechanisms affecting their use (public policy, use rights, contracts, etc.) and the effects of their uses on the sustainability of housing within the context of the built environment. The potential of the institutional regimes framework is explored for its suitability to the many considerations of housing resilience. By identifying all the goods and services offered by the resource 'housing stock', researchers and decision-makers could improve the resilience of housing by better accounting for the ecosystem services used by housing, decreasing the vulnerability of housing to disturbances, and maximizing recovery and reorganization following a disturbance. The institutional regimes framework is found to be a promising tool for addressing housing resilience. Further questions are raised for translating this conceptual framework into a practical application underpinned with empirical data.

Iowa Comprehensive Heart Disease and Stroke Plan, 2010-2014, March 22, 2010

Heart disease is the number one cause of death for both men and women nationally as well as in the state of Iowa, while stroke is the third leading cause of death. These two diseases are often grouped together under the broader term ―cardiovascular disease‖ (CVD), which accounts for one-third of all deaths within the state. Ongoing efforts to increase prevention of, and improve care for, those who experience CVD have resulted in a decline in the number of deaths in Iowa caused by these conditions. In 1991, the death rate as a result of cardiovascular disease was 344.9 per 100,000 people; by 2006, that number had fallen to 239.9. Deaths as a result of stroke have also dropped, from 74.7 in 1991 to 57.4 in 2006.1 Although progress has been made; these illnesses are still major causes of death and serious disability for many Iowans. Despite the fact that some progress has been made through past efforts, current data show that the journey must continue to achieve the long, quality filled lives that Iowans deserve, free of chronic disease. Up to this point, there has been a lack of involvement by stakeholders against heart disease and stroke in Iowa. Causes of CVD are largely known and preventable, and more must be done to educate and spread this information throughout the state. This comprehensive statewide plan is a call to action to improve prevention, treatment, and management of heart disease and stroke in Iowa. Through the commitment and collaborative efforts of many, the Iowa Comprehensive Heart Disease and Stroke Plan 2010-2014 provides a guide to improve the health status of all Iowans. The people of Iowa have a long history of working together to do the right thing. We must rise to the challenge of lowering the incidence of heart disease and stroke through early and ongoing education that stresses prevention and healthy lifestyle choices, medical services that provide evidence-based, effective treatment and long term care management without disparity, and environmental policies that support the prevention of heart disease and stroke in our schools, work sites, and communities. This strategic plan is a guide to improving cardiovascular health in Iowa through 2014.

Deontological and altruistic guilt: evidence for distinct neurobiological substrates.

The feeling of guilt is a complex mental state underlying several human behaviors in both private and social life. From a psychological and evolutionary viewpoint, guilt is an emotional and cognitive function, characterized by prosocial sentiments, entailing specific moral believes, which can be predominantly driven by inner values (deontological guilt) or by more interpersonal situations (altruistic guilt). The aim of this study was to investigate whether there is a distinct neurobiological substrate for these two expressions of guilt in healthy individuals. We first run two behavioral studies, recruiting a sample of 72 healthy volunteers, to validate a set of stimuli selectively evoking deontological and altruistic guilt, or basic control emotions (i.e., anger and sadness). Similar stimuli were reproduced in a event-related functional magnetic resonance imaging (fMRI) paradigm, to investigate the neural correlates of the same emotions, in a new sample of 22 healthy volunteers. We show that guilty emotions, compared to anger and sadness, activate specific brain areas (i.e., cingulate gyrus and medial frontal cortex) and that different neuronal networks are involved in each specific kind of guilt, with the insula selectively responding to deontological guilt stimuli. This study provides evidence for the existence of distinct neural circuits involved in different guilty feelings. This complex emotion might account for normal individual attitudes and deviant social behaviors. Moreover, an abnormal processing of specific guilt feelings might account for some psychopathological manifestation, such as obsessive-compulsive disorder and depression.

Association entre consommation d'alcool et facteurs de risque cardiovasculaire: une étude sur la population lausannoise. [Association between alcohol consumption and cardiovascular risk factors: a narrative review]

Alors que la consommation modérée d'alcool est liée à un risque plus faible de développer une maladie coronarienne, l'impact d'une consommation plus importante d'alcool sur les facteurs de risque cardiovasculaire (FRCV) et la maladie coronarienne est moins clair. Nous avons étudié l'association entre la consommation d'alcool, les FRCV et l'estimation du risque à dix ans de faire un événement cardiovasculaire dans l'étude populationnelle lausannoise CoLaus. Dans cette étude, 73% des participants consomment de l'alcool, 16% consomment de 14 à 34 unités d'alcool par semaine et 2% consomment 35 unités ou plus par semaine. Cet article montre notamment l'impact d'une consommation importante d'alcool sur les FRCVet passe en revue les liens entre la consommation d'alcool, le type de boissons et les FRCV. [Abstract] Moderate alcohol consumption has been associated with lower coronary heart disease (CHD) risk. However, the impact of higher alcohol consumption on cardiovascular risk factors (CVRFs) is conflicting. We examined the association between alcohol consumption, CVRFs and the estimated 10-year CHD risk in the population-based CoLaus study in Lausanne, Switzerland. Among 5'769 participants without cardiovascular disease, 73% of the participants were alcohol drinkers; 16% consumed 14-34 drinks/week and 2% consumed >= 35 drinks/week. This article shows the impact of high alcohol consumption on CVRFs and reviews the literature on the associations between alcohol consumption and CVRFs.

Amostragem para a estimativa de produção de sementes de castanheira‑do‑brasil em floresta nativa

O objetivo deste trabalho foi determinar o tamanho necessário da amostra para estimar a produção individual e populacional de árvores de castanheira‑do‑brasil (Bertholletia excelsa) em floresta nativa, bem como avaliar diferentes sistemas de amostragem. Os dados foram obtidos em um castanhal na região do Itã, em Caracaraí, RR. A produção de frutos e sementes de 239 árvores foi monitorada de 2007 a 2010. Com base na relação das características das árvores (diâmetro, tipo morfológico e variáveis de copa) com a produção, o tipo de alocação e a periodicidade da amostra, foram testados sete procedimentos de amostragem. Para verificar a precisão e a acurácia, foram tomadas 128 amostras da população e calculados o erro‑padrão da média, o intervalo de confiança e o erro absoluto. Para estimar a produção de uma árvore a 1% de probabilidade, é necessário amostrar, em média, 97% dos frutos. Para o limite de erro de 10%, é necessário amostrar 33% dos frutos. A amostragem contínua, estratificada pelo diâmetro à altura do peito em seis estratos, e a alocação proporcional ao número de árvores na classe diamétrica são os procedimentos de amostragem mais indicados.

Carbon-isotope stratigraphy and ammonite faunal turnover for the Middle Jurassic in the Southern Iberian palaeomargin

Variations in the stable carbon-isotope ratio of marine and continental sediments can reflect changes in sink and flux modifications of the palaeocarbon cycle. Here we report carbon-isotope compositions of Middle Jurassic marine carbonates from the Betic Cordillera (southern Spain), which represents an ideal region to link the stable carbon-isotope curves directly to ammonite zones and subzones, and thereby for the first time achieve an accurate chronostratigraphic calibration. The five sections studied represent basin and high swell deposits of the Southern Iberian palaeomargin. We find a similar delta C-13 of carbonates between different oceanic areas, suggesting a homogeneous carbon-isotope oceanic reservoir through the Middle Jurassic. The Aalenian-Bajocian transition is a critical period in ammonite evolution; hence the Early Jurassic fauna are replaced by new ammonite families which become dominant throughout the Middle and Late Jurassic. For this reason, we compared the delta C-13 values of carbonates with ammonite diversity and extinction rates at different taxonomical levels in order to explore the possible relationship between the carbon cycle and ammonite evolution. The carbon-isotope values of carbonates are not exactly linearly correlated with the extinction rate and ammonite diversity, but the main faunal turnovers follow minimum delta C-13 values, where extinct taxa are replaced by new ones. Likewise, radiation episodes are associated with increasing delta C-13 values and with transgressive sea-level rise. All these data support the idea that perturbations in the global carbon cycle reflect rapid palaeoenvironmental changes. We made detailed analyses of these faunal turnovers, using them as a proxy to identify major palaeoenvironmental crises in their ecosystems forced by modification in the carbon cycle.

Relação entre toxicidade de proteínas Vip3Aa e sua capacidade de ligação a receptores intestinais de lepidópteros-praga

Resumo:O objetivo deste trabalho foi avaliar a toxicidade de novas proteínas Vip3Aa e sua capacidade de ligação a vesículas de membrana da microvilosidade apical (VMMA) do intestino de lagartas neonatas de Spodoptera frugiperda, Anticarsia gemmatalise Heliothis virescens. Proteínas expressas pelos genes vip3Aa42 e vip3Aa43 mostraram-se tóxicas a S. frugiperda (CL50 de 78,2 e 113 ng cm-2, respectivamente) e A. gemmatalis(CL50 de 239,2 e 57,5 ng cm-2, respectivamente), e pouco tóxicas a H. virescens (CL50>5.000 ng cm-2). Os ensaios de ligação às VMMA mostraram que as proteínas unem-se de forma efetiva aos receptores nas vesículas das espécies avaliadas, mas essa capacidade de ligação somente é efetiva na ativação da toxicidade para as populações avaliadas de S. frugiperdae A. gemmatalis.
