Pleasant dietary habits are necessary for health

02.12.2009
Taste stimulation and its anticipation activates muscle glucose metabolism via 'orexin' neurons in the brain and thereby reduces blood glucose level in mice

Japanese research group led by Professor Yasuhiko Minokoshi and Dr. Tetsuya Shiuchi, scientists at the National Institute for Physiological Sciences, NIPS, Japan, found that meals stimulated with sweet taste and motivated with its anticipation regularly activates "orexin" in the brain and it stimulates muscle glucose metabolism via the sympathetic nervous system, thereby reducing blood glucose level in mice. They report their finding in Cell Metabolism published on Dec 2, 2009.

The research group focused on the function of "orexin" neurons in brain. Orexin is a kind of brain hormones related to sleep/wakefulness and food intake. They found that orexin released in the brain from "orexin" neurons activates glucose metabolism in muscle but not adipose tissue in mice through the preferential activation of the sympathetic nervous system. Furthermore, they found that a pleasant meal with sweet taste stimulation and its anticipation activates orexin neurons and curbs the rise of blood glucose level by activating muscle metabolism via the sympathetic nervous system.

It is known that orexin plays an important role in the regulation of sleep/wakefulness and autonomic nervous system in human as well as experimental animals. Therefore, this finding implies the strong relationship between habits of diet and our health. Pleasant meal with tasty foods (of course, not high calorie) and with family and friends may prevent hyperglycemia by activating orexin neurons. In contrast, irregular dietary habits, especially eating fast food just before sleeping, may cause hyperglycemia and possibly obesity. "Orexin neurons have been shown to decrease the activity at night. Thus, eating just before sleeping may not be able to activate orexin neurons effectively, then resulting in hyperglycemia", said Prof Minokoshi.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

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...

Im Focus: Giant Magnetic Fields in the Universe

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...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

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.
