In today’s 24/7 society, work and social obligations can adversely affect the timing, duration and quality of sleep. One such demand resulting from today’s society is the need for shift work.
The aim of this study is to investigate the effect of one night of total sleep deprivation, as is experienced during the first night of a night shift, on a range of metabolic, inflammatory and cardiovascular and neurobehavioural responses. The responses of shift workers will be compared to those on non shift workers. It is hoped that valuable knowledge will be gained, in particular for those who skip a night’s sleep, for instance, night shift workers.
Previous research has indicated that doing shift work is not without risk and it has been shown to have consequences for the health and wellbeing of an individual, both acutely and in the long term. Sleep deprivation during a night shift can acutely decrease alertness and performance. Doing shift work for a number of years has, for example, been associated with increased risk of cardiovascular disease (CVD). An increased risk of developing CVD has, in part, been shown to be due to elevation of hormone and lipid responses, and is related to changes in the inflammatory system.
Susceptibility to the effects of sleep deprivation is also likely to differ between people. These differences may be a result of the amount of shift work done in the past, lifestyle, sleep patterns and genetics.
Sophie Wehrens, the lead researcher comments: “Today’s 24/7 society puts a very high pressure on people’s sleep patterns. Many people realise this may affect their health, but we do not know exactly how. In addition, it is obvious that not everyone responds in the same way to skipping a night’s sleep. We are therefore very interested to investigate responses to sleep deprivation in the well controlled conditions of our lab. This hopefully will enable us to characterise these responses and to understand the mechanisms underlying them.”

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
