Animal study sheds light on effects of hospital drugs
Chronic use of opiate drugs may alter brain neurons to make animal brains more sensitive to stress, according to a new study. If the research proves applicable to humans, the findings may help explain how hospital patients who have received morphine may be susceptible to stress disorder, attention problems and sleep disturbances. The effects on the brain may also contribute to better understanding of drug addiction.
The study, published in the September 22 issue of the Journal of Neuroscience, was the first to show that chronic opiate use disrupts the stress response of nerve cells in the noradrenergic system. This system, using a neurotransmitter called norepinephrine, influences the brain’s arousal and attention levels when a stressful event occurs.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
