No beneficial effects were found on cognitive function, bone mineral density or plasma lipids when postmenopausal women age 60 years or older took soy protein supplements with isoflavones for one year, according to a study in the July 7 issue of The Journal of the American Medical Association (JAMA).
“The sudden decline in estrogen levels after menopause coincides with acceleration of several aging processes,” according to background information in the article. “On average, bone mineral density (BMD) decreases and cognitive function declines, whereas total cholesterol and low-density lipoprotein cholesterol (LDL-C) [the bad type of cholesterol] increase.” The authors write that some women have taken hormone therapy to counteract some of these changes; however, hormone therapy has short- and long-term risks. Isoflavones, estrogenlike compounds naturally occurring in plant foods, have been suggested as an alternative for traditional estrogen therapy with fewer adverse effects.
Sanne Kreijkamp-Kaspers, M.D., Ph.D., from the University Medical Center, Utrecht, the Netherlands, and colleagues conducted a study with 202 healthy postmenopausal women aged 60 to 75 years between April 2000 and September 2001 in the Netherlands. The women were randomly assigned to receive 25.6 grams of soy protein containing 99 milligrams (mg) of isoflavones or the placebo, a total milk protein as a powder, each of which could be mixed with food or beverages on a daily basis for 12 months. Cognitive testing was performed at baseline and at the final visit, one year later, using several standardized tests. Bone mineral density was measured at baseline and 12 months using dual-energy x-ray absorptiometry (DXA) scans, and plasma lipid levels also were assessed at baseline and 12 months.

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...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
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...
