Adult patients taking the antidepressant drug paroxetine are at higher risk of attempting to commit suicide than those not taking medication. A new analysis, published in BMC Medicine, of previous clinical data on paroxetine use adds the antidepressant to the list of Selective Serotonin Reuptake Inhibitors (SSRIs) that have been shown to increase suicidal tendencies in adult patients with depression.
Ivar Aursnes and colleagues from the University of Oslo, Norway, reanalysed data from 16 selected paroxetine trials. In the trials, patients diagnosed with depression had been randomly given either paroxetine or a placebo drug. Neither the participants nor the researchers conducting the initial studies knew what the participants had been given. Aursnes et al. did a new statistical analysis of the results of these studies, to evaluate the incidence of suicide attempts in both groups. In their analysis, they took into account the amount of time the participants had been exposed to paroxetine. Their results show that there were seven suicide attempts in the group on paroxetine, and only one among the patients on placebo.
Paroxetine has been shown to increase suicidal attempt rates in children and teenagers, but previous studies have failed to reach a conclusion as regards the effects of the drug on suicide attempt rates in adult patients. Gunnell et al., in the February 19th 2005 issue of the BMJ, warned doctors about an increased risk of suicidal behaviour in patients treated with SSRIs. Their conclusion was based on analyses of clinical data submitted by the pharmaceutical companies that produce SSRIs to the Medicine and Healthcare products Regulatory Agency. But Gunnell et al.’s study had not properly included data on paroxetine.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
