Among women in their child-bearing years, even minimal amounts of unwanted hair in male-type patterns – especially in the presence of other subtle changes – may be a sign of a hormonal imbalance linked to a variety of serious side effects and medical conditions, according to the December 2004 issue of the American Journal of Obstetrics and Gynecology.
In a study of 188 women conducted by researchers at Cedars-Sinai Medical Center and the University of Alabama, Birmingham (UAB), 102 subjects with minimal excess hair growth had excessive levels of androgens, "male" hormones that normally exist in women in lesser amounts.
"We know that excess hair growth in the male pattern in women, which we call hirsutism, generally is a good indicator that there is an underlying hormone imbalance. Now this relatively large study shows that nearly 55 percent of women who have minimal unwanted hair growth have an androgen excess-related disorder, primarily the polycystic ovary syndrome," said Ricardo Azziz, MD, MPH, MBA, Chair of Cedars-Sinais Department of Obstetrics and Gynecology, Director of the Center for Androgen-Related Disorders, and Executive Director of the Androgen Excess Society, an international research organization.

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...

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...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
