Rapid Eye Movement Sleep, Sleep Continuity and Slow Wave Sleep as Predictors of Cognition, Mood, and Subjective Sleep Quality in Healthy Men and Women, Aged 20-84 Years.

Abstract: Sleep and its sub-states are assumed to be important for brain function across the lifespan but which aspects of sleep associate with various aspects of cognition, mood and self-reported sleep quality has not yet been established in detail. Sleep was quantified by polysomnography, quantitative Electroencephalogram (EEG) analysis and self-report in 206 healthy men and women, aged 20–84 years, without sleep complaints. Waking brain function was quantified by five assessments scheduled across the day covering objectively assessed performance across cognitive domains including sustained attention and arousal, decision and response time, motor and sequence control, working memory, and executive function as well as self-reports of alertness, mood and affect. Controlled for age and sex, self-reported sleep quality was negatively associated with number of awakenings and positively associated with the duration of Rapid Eye Movement (REM) sleep, but no significant associations with Slow Wave Sleep (SWS) measures were observed. Controlling only for age showed that associations between objective and subjective sleep quality were much stronger in women than in men. Analysis of 51 performance measures demonstrated that, after controlling for age and sex, fewer awakenings and more REM sleep were associated significantly with better performance on the Goal Neglect task, which is a test of executive function. Factor analysis of the individual performance measures identified four latent variables labeled Mood/Arousal, Response Time, Accuracy, and Visual Perceptual Sensitivity. Whereas Mood/Arousal improved with age, Response Times became slower, while Accuracy and Visual perceptual sensitivity showed little change with age. After controlling for sex and age, nominally significant association between sleep and factor scores were observed such that Response Times were faster with more SWS, and Accuracy was reduced where individuals woke more often or had less REM sleep. These data identify a positive contribution of SWS to processing speed and in particular highlight the importance of sleep continuity and REM sleep for subjective sleep quality and performance accuracy across the adult lifespan. These findings warrant further investigation of the contribution of sleep continuity and REM sleep to brain function.

Density-Driven Flows in Evaporating Binary Liquid Droplets.

Abstract: In the evaporation of microlitre liquid droplets, the accepted view is that surface tension dominates and the effect of gravity is negligible. We report, through the first use of rotating optical coherence tomography, that a change in the flow pattern and speed occurs when evaporating binary liquid droplets are tilted, conclusively showing that gravitational effects dominate the flow. We use gas chromatography to show that these flows are solutal in nature, and we establish a flow phase diagram demonstrating the conditions under which different flow mechanisms occur.

Internet Gambling: Preliminary Results of the First U.K. Prevalence Study

Abstract: Technology has always played a role in the development of gambling practices, and new technologies such as Internet gambling may provide many people with their first exposure to the world of gambling. Further to this, Internet gambling could be argued to be more psychologically enticing than previous non-technological incarnations of gambling because of anonymity, accessibility and interactivity. This paper reports on the results of the first U.K. study of Internet gambling; 2098 people were interviewed for their behaviour and attitudes. Results indicated that only 1% of Internet users (n=495) had ever gambled on the Internet and that there was no evidence of problematic gambling behaviour associated with the Internet.

The Cambridge Introduction to Travel Writing

Abstract: Critics have long struggled to find a suitable category for travelogues. From its ancient origins to the present day, the travel narrative has borrowed elements from various genres - from epic poetry to literary reportage - in order to evoke distant cultures and exotic locales, and sometimes those closer to hand. Tim Youngs argues in this lucid and detailed Introduction that travel writing redefines the myriad genres it comprises and is best understood on its own terms. To this end, Youngs surveys some of the most celebrated travel literature from the medieval period until the present, exploring themes such as the quest motif, the traveler's inner journey, postcolonial travel and issues of gender and sexuality. The text culminates in a chapter on twenty-first-century travel writing and offers predictions about future trends in the genre, making this Introduction an ideal guide for today's students, teachers and travel writing enthusiasts.

Increased human pathogenic potential of Escherichia coli from polymicrobial urinary tract infections in comparison to isolates from monomicrobial culture samples.

Abstract: The current diagnostic standard procedure outlined by the Health Protection Agency for urinary tract infections (UTIs) in clinical laboratories does not report bacteria isolated from samples containing three or more different bacterial species. As a result many UTIs go unreported and untreated, particularly in elderly patients, where polymicrobial UTI samples are especially prevalent. This study reports the presence of the major uropathogenic species in mixed culture urine samples from elderly patients, and of resistance to front-line antibiotics, with potentially increased levels of resistance to ciprofloxacin and trimethoprim. Most importantly, the study highlights that Escherichia coli present in polymicrobial UTI samples are statistically more invasive (P<0.001) in in vitro epithelial cell infection assays than those isolated from monomicrobial culture samples. In summary, the results of this study suggest that the current diagnostic standard procedure for polymicrobial UTI samples needs to be reassessed, and that E. coli present in polymicrobial UTI samples may pose an increased risk to human health.
