Hormone researchers at the University of Houston (UH) have their sights set on providing long-term treatment options for diabetes, obesity and cardiovascular diseases by better understanding estradiol, the most potent naturally occurring estrogen.
They now believe that this estrogen hormone is a prominent regulator of several body functions in both females and males. While estradiol is more commonly associated with processes and diseases specific to women, the team determined that the hormone actually functions as a unisex hormone with multiple actions. Research has indicated that when there is an excessive or insufficient amount of estradiol present, the metabolic network becomes imbalanced, which can result in metabolic diseases.
"Female hormones have always been associated with the menstrual cycle, pregnancy, breast-feeding and some diseases, such as osteoporosis and breast cancer, typically associated with women," said Dr. Rodrigo Barros, a research assistant professor with the UH Center for Nuclear Receptors and Cell Signaling (CNRCS). "Our group, however, has discovered that one of these hormones, estradiol, has much wider actions than previously thought. It is no longer considered exclusively a 'female sex hormone,' but a 'unisex hormone' with multiple actions across several organ systems."
Working with CNRCS director and professor Dr. Jan-Åke Gustafsson, Barros says that part of their research is dedicated to understanding how estradiol regulates feeding and food metabolism, explaining that this hormone is involved with several metabolic diseases, including eating disorders, obesity and diabetes.
"We believe that all the systems in the body involved with food consumption and metabolism, which include the brain, liver, pancreas, heart, muscles and fat, are connected by estradiol, resulting in a 'metabolic network' regulated by the hormone," Barros said. "Our evidence shows that when too much or too little estradiol is available, this delicate network loses its balance and metabolic diseases set in."
This research has important implications for the average consumer, as well as for physicians. While hormones like estradiol are important for the adequate maintenance of body functioning, they may pose serious risks to a person's health if misused as supplements. This comes into play when people use alternative forms of hormones, such as natural plant derivatives, that may be harmful if used inappropriately.
For specialists dealing with hormonal treatments, this research underscores that they should be aware that several organs and body functions are affected when estradiol is prescribed and may cause or worsen metabolic diseases. Due to the number of organs and functions affected by fluctuating levels of estradiol, its use as a hormonal treatment for patients with delayed puberty, menopausal symptoms, osteoporosis and prostate cancer is a source of debate within the medical and research communities. Exploring the impact of such treatments as reported by Barros and Gustafsson is helpful for keeping these professionals abreast of new research and guidelines.
Their findings are described in an invited review titled "Estrogen Receptors and the Metabolic Network." The report appeared in the September issue of the research journal Cell Metabolism, a high-impact monthly research journal in the Cell Press publishing network that chronicles notable research on salient scientific discoveries.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
