This paper compares the auditory steady state response (ASSR) thresholds with the click-evoked and tone burst auditory brainstem response (ABR) thresholds in their ability to predict known behavioral thresholds in normal-hearing adults.

Among younger adults, the ability to willfully regulate negative affect, enabling effective responses to stressful experiences, engages regions of prefrontal cortex (PFC) and the amygdala. Because regions of PFC and the amygdala are known to influence the hypothalamic-pituitary-adrenal axis, here we test whether PFC and amygdala responses during emotion regulation predict the diurnal pattern of salivary cortisol secretion. We also test whether PFC and amygdala regions are engaged during emotion regulation in older (62- to 64-year-old) rather than younger individuals. We measured brain activity using functional magnetic resonance imaging as participants regulated (increased or decreased) their affective responses or attended to negative picture stimuli. We also collected saliva samples for 1 week at home for cortisol assay. Consistent with previous work in younger samples, increasing negative affect resulted in ventral lateral, dorsolateral, and dorsomedial regions of PFC and amygdala activation. In contrast to previous work, decreasing negative affect did not produce the predicted robust pattern of higher PFC and lower amygdala activation. Individuals demonstrating the predicted effect (decrease s attend in the amygdala), however, exhibited higher signal in ventromedial prefrontal cortex (VMPFC) for the same contrast. Furthermore, participants displaying higher VMPFC and lower amygdala signal when decreasing compared with the attention control condition evidenced steeper, more normative declines in cortisol over the course of the day. Individual differences yielded the predicted link between brain function while reducing negative affect in the laboratory and diurnal regulation of endocrine activity in the home environment.

Although consuming adequate amounts of fruits and vegetables reduces the risk of developing chronic diseases, it is widely recognized that young adults’ intakes are currently well below the Department of Health’s recommended five portions a day, with men consuming even less than women. One approach in the UK has been to introduce health campaigns such as the 5 A DAY programme; however, little is currently known about how well their messages are understood amongst young adults. This study examined current knowledge of the 5 A DAY message in young adults, as well as the perceived benefits and remaining barriers towards consuming more fruits and vegetables. In total, four focus groups were conducted using male (n = 22) and female (n = 18) students at the University of Reading. Content analysis revealed that while participants were aware of the 5 A DAY recommendation, there was widespread confusion regarding the detail. In addition, men were less accepting of the message than women, reporting greater disbelief and a lack of motivation to increase intake. Finally, a range of barriers was reported by participants of both genders, despite the perceived beneficial effects for health and appearance. The results illustrate a considerable gap between awareness and knowledge of the 5 A DAY message, and underscore the challenge that changing behaviour in young adults represents. As well as stepping up education- and skill-based health campaigns, more targeted gender specific interventions will be needed to achieve sustained increases in fruit and vegetable intake.

Human selenium (Se) requirements are currently based on biochemical markers of Se status. In rats, tissue glutathione peroxidase-1 (Gpx1) mRNA levels can be used effectively to determine Se requirements; blood Gpx1 mRNA levels decrease in Se-deficient rats, so molecular biology-based markers have potential for human nutrition assessment. To study the efficacy of molecular biology markers for assessing Se status in humans, we conducted a longitudinal study on 39 subjects (age 45 +/- 11) in Reading, UK. Diet diaries (5 day) and blood were obtained from each subject at 2, 8, 17 and 23 weeks, and plasma Se, glutathione peroxidase (Gpx3) enzyme activity, and selenoprotein mRNA levels were determined. There were no significant longitudinal effects on Se biomarkers. Se intake averaged 48 +/- 14 mu g/d. Plasma Se concentrations averaged 1.13 +/- 0.16 mu mol/l. Plasma Se v. energy-corrected Se intake (ng Se/kJ/d) was significantly correlated, but neither Gpx3 activity v. Se intake (ng Se/kJ/d) nor Gpx3 activity v. plasma Se was significantly correlated. Collectively, this indicates that subjects were on the plateaus of the response curves. Selenoprotein mRNAs were quantitated in total RNA isolated from whole blood, but mRNA levels for Gpx1, selenoprotein H, and selenoprotein W (all highly regulated by Se in rodents), as well selenoprotein P, Gpx3, and phospholipid hydroperoxide glutathione peroxidase were also not significantly correlated with plasma Se. Thus selenoprotein molecular biomarkers, as well as traditional biochemical markers, are unable to further distinguish differences in Se status in these Se replete subjects. The efficacy of molecular biomarkers to detect Se deficiency needs to be tested in Se-deficient populations.

The role of preschool phonological awareness in early reading and spelling skills was investigated in the transparent orthography of Turkish. Fifty-six preschool children (mean age=5.6 years) were followed into Grade 2 (mean age=7.6 years). While preschool phonological awareness failed to make any reliable contribution to future reading skills, it was the strongest longitudinal correlate of spelling skills measured at the end of Grades 1 and 2. Overall findings suggested that phonological awareness may be differentially related to reading and spelling, and that spelling is a more sensitive index of phonological processing skills. In this study, verbal short-term memory emerged as the most powerful and consistent longitudinal correlate of reading speed. This finding raised important questions about the component processes of reading speed, and the role of memory and morphosyntactic skills in an agglutinative and transparent orthography such as Turkish.
