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.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
