Genes may influence the level of vitamin d, But Only in Winter: Study (HealthDay)

MONDAY, November 29, HealthDay News)--Genetics affect the person's vitamin D levels during the winter, even if other factors have greatest impact on the results of research in the summer, the new show.

Vitamin d, which is necessary to maintain the health and a strong bones is, of course, losing the body when exposed to sunlight. Most foodstuffs do not contain vitamin D, unless it is added to the distillation.

Emory University researchers examined 310 identical twins and 200 when the average age of 55, the twins, the 25-hydroxyvitamin D vitamin D, the symbol of the levels of exposure to blood.

Average level was sufficient, but the level was higher in the summer than in winter. The researchers said, 70% of the variation in the levels of vitamin D could be due to genetic factors in the winter.

None of the variation in the summer it was, however, such as genetics, but in order to ensure that exposure to sunlight and latitude, and other lifestyle, such as the amount of vitamin D in the diet.

In the fields of research, Dr. Cristina Karohl and colleagues, will be published in the American Journal of Clinical nutrition in December-a problem.

For more information about how the studies continue to all of these factors, the impact of vitamin D levels, it would be useful in the field of public health experts as they consider ways of ensuring an adequate vitamin D all populations, research by the authors of the journal from the Publisher is found in a press release.

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....
