Genes influence the level of Vitamin D, but only in Winter. Studies (HealthDay)

MONDAY, November 29, HealthDay News)--genetics influence vitamin D levels a people during the winter while other factors have the biggest impact in summer, the results of a new study shows.

Vitamin D, which was needed to maintain health and physical strength, responsibilities, burned the body when exposed to the Sun. Most foods that don't have vitamin D, he added.

Emory University researchers so jumeaux check 310 and 200 nonidentical jumeaux, average age 55, percent level of 25-hydroxyvitamin d, an exposure of marqueur vitamin d.

Average level, but adequate level was higher in the summer than in winter. Dry said 70 percent of the variation in vitamin D concentrations in the winter could attribuée to genetic factors.

However, none of the variation in summer the were due to genetics, but rather in order to environmental conditions like sun exposure and latitude, and other factors such as number of other vitamin D in the diet.

The study, Dr. Cristina Karohl and his partners, published in the American newspaper nutrition clinic in December.

Further study to learn more about how all these factors influence vitamin D level would be useful to public health experts that make up a way to assure adequate vitamin D levels in all populations, author studies in a news release from the newspaper Publisher.

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....
