In search of vegetable preparations for nervous system diseases prophylaxis and treatment Russian researchers have turned to green tea. Specialists of the Kuban State University, the Kuban Research-and-Production Laboratory of Physiologically Active Substances and the Institute of Brain (Russian Academy of Medical Sciences) have discovered that ethanolic extract of green tea stimulates spinal cord neurons’ regeneration.
Spinal ganglia were cultivated in nutrient medium. Dry extract in different concentrations was added to the medium. The researchers judged on neurons state and their capacity for regeneration by the number and length of nerve cell processes. The length and number of processes account for the ‘quality of communication’ between neurons and ultimately the ability of the nervous system section to fulfill its functions. The ability to restore bonds is the rate of cells’ resistance to neurodegenerative diseases, for example, ischemia or Parkinsons disease.
The green tea extract had the most apparent stimulatory action in concentration of 0.004-0.006 percent. On the second day of cultivation, the number of cell processes started to grow as compared to the background ones, and then the length of cell processes began to increase. On the fourth day of experiment, the difference between the background and experimental groups was maximum both in terms of processes number and length. On the fifth day, the green tea extract effect disappeared.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
