The per-ARNT-sim (PAS) domain represents an ancient protein module that can be found across all kingdoms of life. The domain functions as a sensing unit for a diverse array of signals, including molecular oxygen, small metabolites, and light. In plants, several PAS domain-containing proteins form an integral part of the circadian clock and regulate responses to environmental change. Moreover, t...

Relationships among a modifiable situational factor (unit cohesion), prior stressful life events, and posttraumatic stress disorder (PTSD) symptoms were assessed in 1,579 U.S. Army soldiers with no history of contemporary war zone deployment. It was predicted that unit cohesion would attenuate the dose-response relationship between past stressor exposures and PTSD symptoms at relatively moderat...

nearest kidney transplant unit as many potential donors as are available. In doing this doctors will need to enlarge their vision from concern for the patients under their own care to include other patients who may otherwise die. From this survey it seems that a sustained campaign is required to improve the communication between doctors and nurses caring for potential donors and those working i...

Sustainable manufacturing (SM) concerns the manufacture of products with regard to environmental, social, and economic impacts over the entire life cycle. With a primary focus on environmental concerns, life cycle assessment (LCA) can support SM practices. The life cycle inventory (LCI) is a key phase of LCA, and this paper considers the integration of manufacturing unit processes (MUPs) into s...

PURPOSE Death at the beginning of life is tragic but not uncommon in neonatal intensive care units. In Portugal, few studies have examined the circumstances surrounding the final moments of neonates. We evaluated the care given to neonates and their families in terminal situations and the changes that had occurred one decade later. DESIGN AND METHODS We analyzed 256 charts in a retrospective ...

BACKGROUND In addition to mortality, Health Related Quality of Life (HRQOL) has increasingly been claimed as an important outcome variable. The aim of this study was to assess HRQOL and independence in activities of daily living (ADL) six months after discharge from an Intensive Care Unit (ICU), and to study its determinants. METHODS All post-operative adult patients admitted to a surgical IC...

Apparent size of the photosynthetic unit (chlorophyll/O(2) per flash) was estimated by O(2) yield of repetitive short flashes on cell samples taken at various times from a synchronized culture (14-hour light, 10-hour dark) of Scenedesmus obliquus. Unit size was essentially invariant (< 10% variation) with a mean value of 1750 chlorophyll/O(2) per flash. In contrast, the light-saturated photosyn...

OBJECTIVE To examine the reliability of the SF-36 general health questionnaire when used to evaluate the health status of critically ill patients before admission to intensive care and to measure their health-related quality of life prior to admission and its relation to severity of illness and length of stay in the intensive care unit. METHODS Prospective cohort study conducted in the intens...

OBJECTIVE To estimate the incidence of limitations to Advanced Life Support in critically ill patients admitted to an intensive care unit with integrated palliative care. METHODS This retrospective cohort study included patients in the palliative care program of the intensive care unit of Hospital Paulistano over 18 years of age from May 1, 2011, to January 31, 2014.
