BACKGROUND Moderate alcohol consumers have lower rates of cardiovascular disease than abstainers. One proposed mechanism is a beneficial effect on hemostatic parameters, but previous studies have provided conflicting results. METHODS AND RESULTS We measured levels of fibrinogen, plasma viscosity, von Willebrand factor, factor VII, plasminogen activator inhibitor antigen-1, and tissue plasmino...
BACKGROUND Negative energy balance (NEB) is a common pathological foundation of ketosis and fatty liver. Liver and fat tissue are the major organs of lipid metabolism and take part in modulating lipid oxidative capacity and energy demands, which is also a key metabolic pathway that regulates NEB develop during perinatal period. Fibroblast growth factor-21 (FGF-21) is a recently discovered prote...
to determine the prevalence of pituitary hormone deficiencies after moderate traumatic brain injury (tbi). we conducted a prospective cohort and included 75 patients with moderate tbi with gcs between 9 and 13 who referred to emergency department of shariati hospital, tehran/iran, during 2004-2007. pituitary hormones were assessed 3 and 6 months after injury. in 3rd month post-injury, 39 cases ...
— This paper presents the progress and final state of CAIN-21, an extensible and metadata driven multimedia adaptation in the MPEG-21 framework. CAIN-21 facilitates the integration of pluggable multimedia adaptation tools, automatically chooses the chain of adaptations to perform and manages its execution. To drive the adaptation, it uses the description tools and implied ontology established b...
In this paper, we present our work on two aspects of multimedia adaptation: knowledge-based single media adaptation and semantic adaptation of multimedia documents. For the former, we propose support of adaptation by direct hinting in the scope of MPEG-21. For the latter, which is the main part of the presented work, we introduce the description of semantic dependencies between media objects of...
Within an MPEG-21 architecture, the two key concepts are the Digital Item, representing multimedia content, and Users, interacting with this content. MPEG-21 introduced Digital Item Processing to allow content authors to describe suggested processing of their Digital Items. It standardizes ways to insert functionality into a Digital Item, as such, creating a dynamic and interactive multimedia f...
Older adults today consume more alcohol than previous generations, the majority being social drinkers. The effects of heavy alcohol use on brain functioning closely resemble age-related changes, but it is not known if moderate-heavy alcohol consumption intensifies brain aging. Whether a lifestyle of moderate-heavy alcohol use in older adults increased age-related brain changes was examined. For...
