BACKGROUND Analysis of respiratory mechanics during mechanical ventilation (MV) is able to estimate resistive, elastic and inertial components of the working pressure of the respiratory system. Our aim was to discriminate the components of the working pressure of the respiratory system in infants on MV with severe bronchiolitis admitted to two PICU's. METHODS Infants younger than 1 year old w...

Submersion and increased pressure (depth) characterize the diving environment and may independently increase demand on the respiratory system. To quantify changes in respiratory mechanics, this study employed a unique protocol and techniques to measure, in a hyperbaric chamber, inspiratory and expiratory alveolar pressures (interrupter technique), inspiratory and expiratory resistance in the ai...

After an egg is fertilized, the resulting zygote contains bothmaternal and paternal mitochondria. With few exceptions, however, mitochondrial DNA (mtDNA) is transmitted solely through thematernal lineage. Howdo cells dispose of paternalmitochondria?New research from two independent groups provides evidence that paternal mitochondria are actively and rapidly degraded by autophagy, a highly regul...

Previous critical readings of Toni Morrison’s novels, especially Paradise, largely emphasise the universal themes explored in her novels, namely, feminism, culture, psychology, and of course, her remarkable presentation of African-Americans in racial and cultural conflicts. Yet, there are major areas that remain unexplored in her works. One of the most conspicuous absences is Morrison’s dominan...

In his poem “Rabbi Ben (sic Ibn) Ezra,” Robert Browning acknowledges the multitude of physical and nonphysical determinants of life’s richness. His narrator sees these influences as interwoven and spanning the ages from youth through adulthood in timeless fashion. In this week’s issue of Circulation, Bouchardy and colleagues2 determine the prevalence of atrial (tachy)arrhythmias (AA) in adults ...

Two studies tested whether observers could differentiate between two facets of pride-authentic and hubristic-on the basis of a single prototypical pride nonverbal expression combined with relevant contextual information. In Study 1, participants viewed targets displaying posed pride expressions in response to success, while causal attributions for the success (target's effort vs. ability) and t...

Most previous research into gender role stereotypes in the mass media has concentrated on television or print. Using content analysis, gender role stereotyping in radio commercials was examined. The goals of the study were to: (1) provide current data on level and content of gender stereotyping in Portuguese radio advertising; (2) compare levels of stereotyping in three countries. One hundred a...

Against the background of the turn towards constructivism and its impact on the current discussion of methodology, the author of the article reconstructs the specific, interactive plausibilization that autobiographical narrative achieves. The analysis focuses on those sequences where the narrator describes her language acquisition processes. Behavioural data (her elaborate knowledge of German, ...

We describe witness-narrator agents, a framework for collaborative narrative generation in persistent virtual environments such as massively multiplayer online role playing games (MMORPGs). Witness-narrator agents allow reports of events in the environment to be published to external audiences so that they can keep up with events within the game world (e.g., via a weblog or SMS messages), or fe...
