Marking anorexia with a brain protein
Eating disorders are frequently seen as psychological or societal diseases, but do they have an underlying biological cause? A new study shows that the levels of a brain protein differ between healthy and anorexic women. view more (2009-06-24)
A new and safer technique in heart surgery
The new technique of SELECTIVE CEREBRAL PERFUSION has been successfully applied for the first time in the Basque Autonomous Community (B.A.C.). Surgeons keep a patient in a state of hibernation at 15 degrees centigrade, without brain activity and with heart circulation and respiratory activity at a standstill for one hour while an aorta implant is... view more...

Mesh-like Network of Arteries Adjusts to Restore Blood Flow to Stroke-Injured Brain
A grid of small arteries at the surface of the brain redirects flow and widens at critical points to restore blood supply to tissue starved of nutrients and oxygen following a stroke, a study published this week has found. view more (2009-02-02)
New insights into how brain responds to viral infection
Scientists at Columbia University Mailman School of Public Health have discovered that astrocytes, supportive cells in the brain that are not derived from an immune cell lineage, respond to a molecule that mimics a viral infection using cellular machinery similar to that used by classical immune cells in the blood. view more (2009-04-01)
Color contrast is 'seen' by the brain early doors
Colour contrast is detected much earlier in the brain than previously thought, a new study shows. view more (2007-09-10)
A crystal ball for brain cancer?
UCLA researchers have uncovered a new way to scan brain tumors and predict which ones will be shrunk by the drug Avastin -- before the patient ever starts treatment. view more (2009-07-30)
Constipation in women linked to anxiety, depression, and feeling "unfeminine"
Chronic constipation in some women is linked to anxiety, depression, and feeling "unfeminine," suggests a study in Gut. Researchers from St Mark's Hospital, Middlesex, studied 34 women between the ages of 19 and 45 who had suffered from constipation for five years or more. The study group was then compared with women who had no history... view more... (2001-07-11)
Reef boom beats doom
Marine scientists say they are astonished at the spectacular recovery of certain coral reefs in Australia's Great Barrier Reef Marine Park from a devastating coral bleaching event in 2006. view more (2009-04-23)
LSUSHC researchers find potential new target for hypertension treatment
Huijing Xia, PhD, a postdoctoral research associate in the lab of Eric Lazartigues, PhD, Assistant Professor of Pharmacology at LSU Health Sciences Center New Orleans, is the lead author on a paper reporting that a recently identified enzyme in the brain plays a critically important role in the central regulation of blood pressure. view more (2009-02-02)
Epilepsy and brain pathology linked together by the protein ADK
The brain of individuals who suffer from epilepsy is characterized by astrogliosis, a brain pathology evidenced by a complex series of changes in the morphology and function of brain cells known as astrocytes. view more (2008-01-03)
Low to moderate blood alcohol level linked to reduced mortality following traumatic head injury
Patients who have low to moderate blood alcohol levels may be less likely to die after arriving at the hospital with a traumatic brain injury than those with no alcohol in their bloodstream, according to a report in the December issue of Archives of Surgery, one of the JAMA/Archives journals. view more (2006-12-19)
Bottleneck in Blood Supply Makes Brain Vulnerable to Strokes
A team of UC San Diego physicists and neuroscientists has discovered a bottleneck in the network of blood vessels in the brain that makes it vulnerable to strokes. The finding may explain the origin of the puzzling damage to the brain's gray matter often detected in brain scans, especially among the elderly. view more (2007-01-05)
First results from novel anti-angiogenic drug trial in patients
"Surprisingly effective" says French research team Frankfurt, Germany: A new drug that targets tumour blood vessels has produced a surprisingly effective response in its first patient study - shrinking the tumours in a number of patients treated so far, according to researchers carrying out the study at the Institut Gustave Roussy in Villejuif,... view more...

Pregnancy situations have impact on brain development in pre-term infants
Brain development in infants who are born very prematurely is still incomplete. Factors that cause premature birth may have an impact on the development of the premature infant's brain both during pregnancy and later on after birth. view more (2008-08-28)
Researchers writing story of the 'alcoholic lung'
Chronic alcohol abuse disrupts the proteins that keep fluids out of the lung, lowers a protective antioxidant, disrupts immune defenses and can lead to a condition known as 'alcoholic lung,' according to research to be presented at the conference, "Physiological Genomics and Proteomics of Lung Disease." view more (2006-11-03)
Discarded human debris threatens global biodiversity
Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30 remote islands around the globe, from the Arctic... view more...

Omega-3s boost grey matter, findings may explain why omega-3s seem to improve mood
Omega-3 fatty acids, found in fatty fish like salmon, are associated with increased grey matter volume in areas of the brain commonly linked to mood and behavior according to a University of Pittsburgh study. view more (2007-03-07)
Ball to occlude the aorta during cardiopulmonary resuscitation
Jesus Manuel Labandeira in his doctoral thesis, read in the University of Navarre, tested this technique in pigs due to the similarity to the human cardiovascular system. According to the results obtained by doctor Labandeira, the use of a occlusion ball in the aorta duplicates the blood pressure that goes to heart and brain during cardiopulmonary... view more...

Packing the home in a Dewars flask
Cars and homes have one thing in common: They consume energy in the form of oil or gas. Energy-efficient vehicles typically make use of lightweight materials and improved engine technologies, and soon home builders will also need to pay greater attention to environmental concerns in their designs. New legislation became effective in Germany last... view more... (2003-04-24)
New treatment for severe malaria
The most dangerous form of malaria is difficult to treat and claims two million lives a year. Now, researchers at Karolinska Institutet in Sweden have developed a powerful new weapon against the disease. view more (2006-10-02)
