Gene impedes recovery from alcoholism

16.11.2011
People who are alcohol-dependent and who also carry a particular variant of a gene run an increased risk of premature death. This is a recent finding from the interdisciplinary research at the Department of Psychology and the Sahlgrenska Academy at the University of Gothenburg, Sweden.

Researchers in the longitudinal project Göteborg Alcohol Research Project (GARP) have been investigating the dopamine D2 receptor gene and found that a variant of this gene is overrepresented in people with severe alcohol dependency, and that it is linked to a number of different negative consequences that can be of vital significance to the person affected.

“Our research shows that alcohol-dependent individuals, who are also carriers of this gene variant, run 10 times the risk of dying prematurely, compared with the average population,” says Claudia Fahlke, a representative from the research team.

In a study published recently in the journal Alcohol and Alcoholism (issue 46), the research team shows that this gene variant also appears to be associated with a higher tendency among these individuals to suffer a relapse, even if they have undergone treatment for their alcohol dependency. This may provide one explanation as to the higher mortality rate in people suffering from alcohol dependency, who are carriers of this gene variant.

“This knowledge emphasises the importance of developing methods for early identifying individuals who are also carriers of this gene variant, since the consequences can be so serious,” says Jan Balldin at the Sahlgrenska Academy, University of Gothenburg.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
