eing made (mRNA profiling). Short exposures to common sediment contaminants result in patterns of mRNA profiles that
indicate the class and type of the bioavailable chemical. Short analysis time and very high sample throughput enable this
approach to be used as a means to rapidly screen large numbers of sediment samples for exposure and/or toxicity. These
analyses are faster and cheaper than traditional priority pollutant analysis with the added potential of identifying bioavailable
contaminants by the effect they cause in a bioassay organism.

Several studies have been performed on the cardiovascular response to physical and psychical stress and their value as
early predictors of hypertension. The conclusions of these studies have been discrepant or even opposite. These discrepancies
could be due in part to factors such as the time when the test is done, the degree of training of the subject in relation with the
test, or the gender, usually ignored in the design of the trials. We have tested the statistically significant influence of these
factors in the cardiovascular response to a physical and psychical test repeated several times at different circadian times in
normotensive volunteers of both genders.

Nitric Oxide in Astrocyte-Neuron Signaling

Astrocytes, a subtype of glial cell, have recently been shown to exhibit the elevations in response to neurotransmitters.
An evalution can propagate to adjacent astrocytes as the wave, which allows an astrocyte to communicate with its neighbors.
Additionally, glutamate can be released from astrocytes via a dependent mechanism, thus modulating neuronal activity and
synaptic transmission.

Mental Stress Related to Peacekeeping Missions. A Survey of the Problem Area

Soldiers and other groups of personnel in peacekeeping missions are at risk of getting mentally injured during their service
abroad. Conditions including threats against one’s own, or the groups, life or security, the suffering of other people and
boredom in combination with state of alert create an environment that demand planning and readiness. Carefully prepared
countermeasures help the personnel to cope with different kinds of situations without getting mental damages. In that Sweden
is prepared to contribute with personnel in conflicts abroad, is there a demand for knowledge and resources in order to cope
with this field. The Swedish Armed Forces, National Police Board and National Rescue Services Board have liability due to
their personnel during international service. This report presents a survey of the authorities program (2000) for handling
mental stress during international missions. The surveys, grouped into before, during and after a mission show great
similarities. Differences between the complete programs and how they function in practice have however not been studied.
