Arginine (ARG) and its precursor citrulline (CIT) are popular dietary supplements, especially for the elderly. However, age-related reductions in lean body mass and alterations in organ functions could change their bioavailability. Pharmacokinetics and tolerance to amino acid (AA) loads are poorly documented in elderly subjects. The objective here was to characterise the plasma kinetics of CIT ...

UNLABELLED Despite growing interest in developing cognitive training interventions to minimize the aging cognitive decline process, no studies have attempted to explore which brain regions support the application of semantic strategies during verbal memory encoding. Our aim was to investigate the behavioral performance and brain correlates of these strategies in elderly individuals using fMRI i...

Incidental and intentional learning and memory for 2 novel flavors were compared in young and elderly subjects. Incidental and intentional learning groups rated 2 new soups on acceptability for different occasions and were tested for memory the next day. On the first day, only the intentional group was asked to memorize the stimuli. With incidental learning, elderly and young were equally good,...

vision of the possible mechanism(s) involved in the hemolytic crisis brought on by other comorbid conditions, such as sepsis. Along the same lines, there is evidence that the HbF levels, an important regulatory mechanism of SCA severity and hemolysis, govern MP concentration by acting on specific MP subtypes. We can imagine that, in SCA children, a storm of various (mainly platelet-derived) pro...

BACKGROUND Sedentary aging is associated with oxidative stress and endothelial dysfunction. The aim of this study was to evaluate the relationship between long-term physical activity, plasma antioxidant status, and conduit artery endothelial function in young and older healthy men. METHODS In young (n = 16) and older athletes (n = 16) and in matched healthy sedentary subjects, endothelium-dep...

Perception of global patterns requires the integration of local orientation information across space. The present study examined whether this integration ability declines in older age. We measured contrast thresholds for discriminating the global orientation of a "C" shaped contour against a blank background in younger and older subjects. Performance of younger subjects improved when the elemen...

Diurnal patterns of plasma euglobulin fibrinolytic activity, estimated by the fibrin plate method, were determined in groups of young normal and older normal subjects, in subjects with type IV hyperlipoproteinemia, and in subjects with coronary artery disease who had normal lipid profiles. The marked diumal increases in fibrinolytic activity observed in the young normal subjects were significan...

Older individuals' ability to maintain core temperature during cold stress is impaired; however, the relative importance of individual characteristics that influence this response are unknown. The purpose of this study was to determine the relative influence of individual characteristics on core temperature and tissue insulation (I(t)) during mild cold stress. Forty-two young (23 +/- 1 yr, rang...
