Do spinal cord injuries cause subsequent brain damage?
University Of Maryland School Of Medicine researchers find that spinal cord injuries can cause brain degeneration
2014-11-14
(Press-News.org) Baltimore, Md., November 14, 2014--Most research on spinal cord injuries has focused on effects due to spinal cord damage and scientists have neglected the effects on brain function. University of Maryland School of Medicine (UM SOM) researchers have found for the first time that spinal cord injuries (SCI) can cause widespread and sustained brain inflammation that leads to progressive loss of nerve cells, with associated cognitive problems and depression.
The research, published recently in two articles, one in of the Journal of Neuroscience, the other in Cell Cycle, highlights the close links between spinal cord injury and loss of brain function, and suggests potential treatment to prevent such changes.
"Animal studies have shown that traumatic brain injury, even mild repeated injuries, can result in progressive brain tissue damage and cognitive decline, as well as widespread brain inflammation. But little research has examined whether these problems occur after spinal cord injuries," said UM SOM anesthesiology professor and noted neurobiologist Alan Faden, MD, who led the study.
"Our studies the first to show that isolated SCI can cause progressive loss of brain cells in key brain regions," said Faden. "The brain degeneration was demonstrated in different experimental models and animals. We also have identified certain molecular mechanisms responsible for these pathological changes and shown that certain drugs can prevent these injuries, including inflammation, brain cell loss, cognitive decline and depressive-like behaviors after injury."
"This is an important and significant advancement in our understanding of the overall effects of spinal cord injuries," said UM SOM Dean E. Albert Reece, MD, PhD, MBA. "The link between spinal trauma and brain function is now more clear, and we believe that further research in this area will offer the hope of new ways to treat this devastating trauma, and perhaps even reverse its effects on the brain."

The University of Maryland School of Medicine was chartered in 1807 and is the first public medical school in the United States and continues today as an innovative leader in accelerating innovation and discovery in medicine. The School of Medicine is the founding school of the University of Maryland and is an integral part of the 11-campus University System of Maryland. Located on the University of Maryland's Baltimore campus, the School of Medicine works closely with the University of Maryland Medical Center and Medical System to provide a research-intensive, academic and clinically based education. With 43 academic departments, centers and institutes and a faculty of more than 3,000 physicians and research scientists plus more than $400 million in extramural funding, the School is regarded as one of the leading biomedical research institutions in the U.S. with top-tier faculty and programs in cancer, brain science, surgery and transplantation, trauma and emergency medicine, vaccine development and human genomics, among other centers of excellence. The School is not only concerned with the health of the citizens of Maryland and the nation, but also has a global presence, with research and treatment facilities in more than 30 countries around the world. http://medschool.umaryland.edu/

Boston (Nov. 14, 2014) - After two bombs exploded near the finish line of the Boston Marathon on April 15, 2013, acute trauma to the ears - such as ruptured eardrums - was immediately apparent to those caring for the victims. However, the full extent of the effect on the ears and hearing of victims was not fully recognized for weeks. In the end, more than 100 patients were evaluated for blast-related otologic injuries.
Almost immediately, Boston researchers set out to detail the types of otologic injury and report on the outcomes of patients undergoing otologic treatment. ...

BOZEMAN, Mont. - Hailstones from three Rocky Mountain storms formed around biological material, then bounced around the clouds picking up layers of ice, according to a new Montana State University study.
The discovery of a biological embryo extends previous findings about the formation of snow and rain, applies to hailstones globally and provides basic information about a little-studied topic, said the researchers who published their findings Nov. 6 in the Journal of Geophysical Research: Atmospheres.
"This is the first paper to really show that biological material ...

Researchers at Western University are using cutting-edge genetic mutation-analysis software developed in their lab to interpret mutations in tumour genome that may provide insight into determining which breast cancer tumours are more likely spread to other parts of the body and which ones won't.
Their findings are published today in the journal, Nature Scientific Reports.
"We are using a unique software program in our lab that looks at a type of mutation called a splicing mutation that is typically overlooked using current methods," said lead author on the study, Stephanie ...

Dartmouth researchers have developed a fluorescence imaging technique that can more accurately identify receptors for targeted cancer therapies without a tissue biopsy. They report on their findings in "Quantitative in vivo immunohistochemistry of epidermal growth factor receptor using a receptor concentration imaging approach," which was recently published in Cancer Research.
"Protein overexpression is a hallmark of certain cancers and is used in clinical oncology to personalize treatment through tumor detection, molecular therapies, and therapeutic monitoring," said ...

Devavrat Shah's group at MIT's Laboratory for Information and Decision Systems (LIDS) specializes in analyzing how social networks process information. In 2012, the group demonstrated algorithms that could predict what topics would trend on Twitter up to five hours in advance; this year, they used the same framework to predict fluctuations in the prices of the online currency known as Bitcoin.
Next month, at the Conference on Neural Information Processing Systems, they'll present a paper that applies their model to the recommendation engines that are familiar from websites ...

A team of scientists specializing in cave biodiversity from the South China Agricultural University (Guangzhou) unearthed a treasure trove of rare blind cave beetles. The description of seven new species of underground Trechinae beetles, published in the open access journal ZooKeys, attests for the Du'an karst as the most diverse area for these cave dwellers in China.
"China is becoming more and more fascinating for those who study cave biodiversity, because it holds some of the most morphologically adapted cavernicolous animals in the world. This is specifically true ...

Athens, Ga. - Researchers at the University of Georgia have discovered that a chemical compound commonly found in coffee may help prevent some of the damaging effects of obesity.
In a paper published recently in Pharmaceutical Research, scientists found that chlorogenic acid, or CGA, significantly reduced insulin resistance and accumulation of fat in the livers of mice who were fed a high-fat diet.
"Previous studies have shown that coffee consumption may lower the risk for chronic diseases like Type 2 diabetes and cardiovascular disease," said Yongjie Ma, a postdoctoral ...

Today's herbaria, as well as all other collections-based environments, are now transitioning their collections data onto the web to remain viable in the smartphone-in-my-pocket age. A team of researchers have examined the importance of these online plant-based resources through the use of Google Analytics (GA) in a study that was published in the open access Biodiversity Data Journal (BDJ).
The amount of plant biodiversity resources freely accessible has exploded in the last decade, but validating an impact factor for these web-based works has remained difficult. A new ...
