(Press-News.org) Bethesda, MD—A group of really brainy scientists have moved closer to growing "therapeutic" brain cells in the laboratory that can be re-integrated back into patients' brains to treat a wide range of neurological conditions. According to new research published online in The FASEB Journal, brain cells from a small biopsy can be used to grow large numbers of new personalized cells that are not only "healthy," but also possess powerful attributes to preserve and protect the brain from future injury, toxins and diseases. Scientists are hopeful that ultimately these cells could be transformed in the laboratory to yield specific cell types needed for a particular treatment, or to cross the "blood-brain barrier" by expressing specific therapeutic agents that are released directly into the brain.
"This work is an example of how integrating basic science and clinical care may reveal privileged opportunities for biomedical research," said Matthew O. Hebb, M.D., Ph.D., FRCSC, a researcher involved in the work from the Departments of Clinical Neurological Sciences (Neurosurgery), Oncology and Otolaryngology at the University of Western Ontario in Ontario, Canada. "It is our hope that the results of this study provide a footing for further advancement of personalized, cell-based treatments for currently incurable and devastating neurological disorders."
Scientists enrolled patients with Parkinson's disease who were scheduled to have deep brain stimulation (DBS) surgery, a commonly used procedure that involves placing electrodes into the brain. Before the electrodes were implanted, small biopsies were removed near the surface of the brain and multiplied in culture to generate millions of patient-specific cells that were then subjected to genetic analysis. These cells were complex in their make-up, but exhibited regeneration and characteristics of a fundamental class of brain cells, called glia. They expressed a broad array of natural and potent protective agents, called neurotrophic factors.
"From an extremely small amount of brain tissue, we will one day be able to do very big things," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "For centuries, treating the brain effectively and safely has been elusive. This advance opens the doors to not only new therapies for a myriad of brain diseases, but new ways of delivering therapies as well."

NASA's TRMM satellite examines Atlantic's Tropical Storm Jerry
2013-09-30
Tropical Depression 11 formed in the central Atlantic Ocean and NASA's TRMM satellite passed overhead and gathered information and identified a "hot tower" that indicated it would strengthen. The depression became Tropical Storm Jerry on Sept. 30 at 10:30 a.m. EDT.
The eleventh Atlantic tropical depression formed around 11 p.m. EDT on Saturday, Sept. 28, about 960 miles/1,540 km east-northeast of the Leeward Islands and was moving north at 9 mph.
When NASA's TRMM or Tropical Rainfall Measuring Mission satellite flew over Tropical Depression 11 on Sept. 30 at 09:28 ...
Traces of immense prehistoric ice sheets
2013-09-30
Geologists and geophysicists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), discovered traces of large ice sheets from the Pleistocene on a seamount off the north-eastern coast of Russia. These marks confirm for the first time that within the past 800,000 years in the course of ice ages, ice sheets more than a kilometre thick also formed in the Arctic Ocean. The climate history for this part of the Arctic now needs to be rewritten, report the AWI scientists jointly with their South Korean colleagues in the title story of the current ...
Cancer biggest killer of Hispanic Texans
2013-09-30
More Hispanic Texans die from cancer than any other cause, according to a new report by the Comparative Effectiveness Research on Cancer in Texas research group.
The report documents cancer as the leading cause of death among Hispanic Texans under the age of 76. Only three percent of Hispanic Texans are older than 75.
Texas's Hispanic population has more than doubled since 1990. Texans of Hispanic ethnicity now comprise 38 percent of the state's population.
The findings are published in a September 2013 special issue of the Texas Public Health Journal, available online ...
Optical sensors improve railway safety
2013-09-30
WASHINGTON, Sept. 30, 2013 – A string of fiber-optic sensors running along a 36-km stretch of high-speed commuter railroad lines connecting Hong Kong to mainland China has taken more than 10 million measurements over the past few years in a demonstration that the system can help safeguard commuter trains and freight cars against accidents. Attuned to the contact between trains and tracks, the sensors can detect potential problems like excessive vibrations, mechanical defects or speed and temperature anomalies. The system is wired to warn train operators immediately of such ...
Is travel to high altitudes more risky for people with diabetes?
2013-09-30
New Rochelle, NY, September 30, 2013—Many factors can affect blood sugar control at high altitudes, and people considering a mountain journey need to understand the potential risks of the environmental extremes, extensive exercise, and dietary changes they may experience. Insulin needs may increase or decrease and individuals with poorly controlled diabetes are especially at risk for hypothermia, frostbite, and dehydration, for example. These and other dangers are described by two doctors who have diabetes and are avid mountaineers in an article published in High Altitude ...
Biochar quiets microbes, including some plant pathogens
2013-09-30
HOUSTON -- In the first study of its kind, Rice University scientists have used synthetic biology to study how a popular soil amendment called "biochar" can interfere with the chemical signals that some microbes use to communicate. The class of compounds studied includes those used by some plant pathogens to coordinate their attacks.
Biochar is charcoal that is produced -- typically from waste wood, manure or leaves -- for use as a soil additive. Studies have found biochar can improve both the nutrient- and water-holding properties of soil, but its popularity in recent ...
Infrared NASA imagery shows some strength in Tropical Depression Sepat
2013-09-30
Tropical Depression Sepat formed in the northwestern Pacific Ocean and NASA's Aqua satellite captured infrared data on the storm, revealing some strong thunderstorms.
Tropical Depression Sepat, the twenty-first tropical depression in the northwestern Pacific Ocean, formed on Sept. 30. NASA's Aqua satellite passed over Sepat on Sept. 30 at 03:23 UTC/Sept. 29 at 11:23 p.m. EDT. As Aqua passed overhead, that Atmospheric Infrared Sounder or AIRS instrument that flies aboard Aqua looked at the storm in infrared light. The AIRS data showed some cold cloud tops of thunderstorms ...
UW engineers invent programming language to build synthetic DNA
2013-09-30
Similar to using Python or Java to write code for a computer, chemists soon could be able to use a structured set of instructions to "program" how DNA molecules interact in a test tube or cell.
A team led by the University of Washington has developed a programming language for chemistry that it hopes will streamline efforts to design a network that can guide the behavior of chemical-reaction mixtures in the same way that embedded electronic controllers guide cars, robots and other devices. In medicine, such networks could serve as "smart" drug deliverers or disease detectors ...
National screening strategy for hepatitis C urged for Canada
2013-09-30
(TORONTO, Canada; Sept. 30, 2013) – Canada should begin screening 'Baby Boomers' for the hepatitis C virus infection, since this age group is likely the largest group to have the illness, and most don't know they have it, say a group of liver specialists in the Toronto Western Hospital Francis Family Liver Clinic. Unlike many other chronic viral infections, early treatment makes hepatitis C curable.
In an article entitled, A Canadian Screening Program for hepatitis C – is Now the Time? published in the Canadian Medical Association Journal (CMAJ) Sept. 30, 2013, by Drs. ...
Depression and mental health services usage
2013-09-30
TORONTO, Sept. 30, 2013—More than half the people in Ontario who reported they had major depression did not use physician-based mental health services in the following year, a new study has found.
"It's concerning to us that many Ontarians with mental health needs are not accessing clinician-based care," said Katherine Smith, the lead author and epidemiologist in the Centre for Research on Inner City Health of St. Michael's Hospital.
"Some people may seek non-medical types of support or care, such as clergy, alternative medicine, psychologists or social workers. But ...
