Infidelity might in Genes (HealthDay)

Friday, December 3 HealthDay News)--Genetics could help explain why some people are more likely to infidelity and promiscuity, a new study.

Look for DNA of 181 analysé old young man who provided a history, in whom all sexual activities and intimate partner. They concluded this récepteur dopamine D4 (DRD4) June plays a big role in sexual behavior.

The first research link and DRD4, influences brain chemistry, to look at what sensation like bank activities and alcohol use.

'' What we found was that man and variant of June DRD4 was more likely to have a history of the name of sex, including one-night and the history of infidelity, '' study leader Justin Garcia, laboratory of anthropology évolutive health and Binghamton University, State University in New York, said in a news Release University.

"The Stimulus to come together in a system of pleasure and reward, that is where the release of dopamine. Of those cases in the name of sex, risk is high, and substantial stimulus variable--all elements which ensure a dopamine '', '' quickly '' Garcia explained.

To them, published in current on news reports, PLoS one should not be seen as an excuse to copy your promiscuity, Garcia.

"Relations [June behavior] these associative, which means that not all and génotype would have one day night you commit infidelity. Indeed, many people without génotype this no longer has a night and commit infidelity, "Garcia said."The study simply suggest that something higher unemployment rates and the quality of genetics that have been given the opportunity to engage in behavior. "

Protein folding via charge zippers

Jan. 18, 2013 — Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, i.e. folding of the molecules, plays a decisive role in the formation of, e.g., pores in the cell membrane. In the journal Cell, researchers of Karlsruhe Institute of Technology and the University of Cagliari are now reporting a novel charge zipper principle used by proteins to form functional units. "It is fascinating to see the elegant basic principles that are used by nature to construct molecular assemblies," explains Anne Ulrich, Director of the KIT Institute for Biological Interfaces. "A charge zipper between the charged side chains is an entirely unexpected mechanism used by membrane proteins to neutralize their charges such that they can be immersed into hydrophobic cell membranes....
