NTS's role in the protection of pre-moxibustion on gastric mucosal lesions
2014-03-31
Moxibustion may have protective effects on the stomach mucous membrane against stress gastric ulcer. The potential mechanism of moxibustion may be mediated by transforming growth factor-α, gastric mucosa cell proliferation, inhibition of apoptosis, and the expression of heat shock protein-70. Previous studies have shown that somatic sensation by acupuncture and visceral nociceptive stimulation can converge in the nucleus tractus solitarii (NTS) where neurons integrate signals impacting on the function of organs. To explore the role of the NTS in the protective mechanism ...
New study finds biochar stimulates more plant growth but less plant defense
2014-03-31
In the first study of its kind, research undertaken at the University of Southampton has cast significant doubt over the use of biochar to alleviate climate change.
Biochar is produced when wood is combusted at high temperatures to make bio-oil and has been proposed as a method of geoengineering. When buried in the soil, this carbon rich substance could potentially lock-up carbon and reduced greenhouse gas emissions. The global potential of biochar is considered to be large, with up to 12 percent of emissions reduced by biochar soil application.
Many previous reports ...

There are two distinct phases in the ...
Wen Dan Tang improves insomnia-related anxiety
2014-03-31
Ghrelin, a brain-gut peptide that induces anxiety and other abnormal emotions, contributes to the effects of insomnia on emotional behavior. In contrast, the traditional Chinese Medicine remedy Wen Dan Tang reduces insomnia-related anxiety, which may perhaps correspond to changes in the brain-gut axis. This suggests a possible relationship between Wen Dan Tang's pharmacological mechanism and the brain-gut axis. Based on this hypothesis, a research team from Beijing University of Chinese Medicine in China generated a sleep deprivation rat model, and orally administered Wen ...
A breakthrough in creating invisibility cloaks, stealth technology
2014-03-31
Controlling and bending light around an object so it appears invisible to the naked eye is the theory behind fictional invisibility cloaks.
It may seem easy in Hollywood movies, but is hard to create in real life because no material in nature has the properties necessary to bend light in such a way. Scientists have managed to create artificial nanostructures that can do the job, called metamaterials. But the challenge has been making enough of the material to turn science fiction into a practical reality.

Early rehabilitation improves postsurgery neurofunctional outcome in spinal tumor children
2014-03-31
In children, primary spinal tumors comprise 4% of all tumors from the central nervous system. Spinal tumors can present with a variety of clinical signs and symptoms in children such as pain followed by motor regression, gait disturbance, sphincter dysfunction, sensory symptoms, torticollis, and kyphoscoliosis. Treatment of spinal tumors is based on tumor type, but surgical resection is the mainstay. Moreover, physical treatment and rehabilitation implementation are necessary in order to minimize the symptoms of the patients and develop present functions. Prof. Nezire Kose ...

The Atlantic Ocean dances with the sun and volcanoes
2014-03-31
Imagine a ballroom in which two dancers apparently keep in time to their own individual rhythm. The two partners suddenly find themselves moving to the same rhythm and, after a closer look, it is clear to see which one is leading.
It was an image like this that researchers at Aarhus University were able to see when they compared studies of solar energy release and volcanic activity during the last 450 years, with reconstructions of ocean temperature fluctuations during the same period.
The results actually showed that during the last approximately 250 years – since ...
Researchers reveal a new pathway through the sodium pump
2014-03-31
A study in The Journal of General Physiology provides new evidence that the ubiquitous sodium pump is more complex—and more versatile—than we thought.
The sodium pump is present in the surface membrane of all animal cells, using energy derived from ATP to transport sodium and potassium ions in opposite directions across the cell boundary. By setting up transmembrane gradients of these two ions, the pump plays a vital role in many important processes, including nerve impulses, heartbeats, and muscular contraction.
Now, Rockefeller University researchers Natascia Vedovato ...
