Association between perceived present working conditions and demands versus attitude to early retirement among construction workers.

Background: Early retirement is an increasing problem in the construction industry. There is limited information about causes leading employees to leave working life early. We have compared construction workers present situation with their perception of future demands at work to avoid early retirement.

Seasonal increase in sea temperature triggers pancreas disease outbreaks in Norwegian salmon farms.

Pancreas disease (PD) is a viral disease causing negative impacts on economy of salmon farms and fish welfare. Its transmission route is horizontal, and water transport by ocean currents is an important factor for transmission. In this study, the effect of temperature changes on PD dynamics in the field has been analysed for the first time.

An integrated, temporal study of the behavioural, electrophysiological and neuropathological consequences of murine prion disease.

We have conducted an integrated study of ME7 prion disease by examining the electrophysiological and neuropathological features of hippocampal slices from behaviourally characterised C57Bl/6J mice 12, 14, 16, 18, 20 and 24 weeks after intracerebral micro-injection of ME7 or normal brain homogenate. We describe the pathogenesis of ME7 as a three-stage process. STAGE ONE: PrPSc deposition, synaptic pathology and abnormal synaptic plasticity.

Stability of intralipid fat emulsion in amino acid solutions.

The stability of the fat emulsion Intralipid 20% depends to a great extent on the electric-repulsive forces between the fat particles. The negative charge of the fat particles (zeta-potential) in Intralipid 20% was measured in large bags containing three different commercially available amino acid solutions, two of which had electrolytes. In each case, the electronegativity was not great enough to give the solution adequate stability.
