Scientists make progress toward fixing infant hearts
R&D Magazine
Researchers at Rice University and Texas Children's Hospital have turned stem cells from amniotic fluid into cells that form blood vessels. Their success offers hope such stem cells may be used to grow tissue patches to repair infant hearts. Researchers hope to grow heart patches from the amniotic stem cells of a fetus diagnosed in the womb with a congenital heart defect.More

Multiple anesthesias linked to ADHD
Multiple exposures to anesthesia at a young age are associated with higher rates of attention-deficit hyperactivity disorder, U.S. researchers found. A Mayo Clinic pediatric anesthesiologist and his colleagues found children exposed to two or more anesthetics before age 3 had more than double the incidence of ADHD than children who had no exposure.More

New device to monitor stroke patients before recurrence
medGadget via The Atlantic
VideoBriefResearchers at Florida's Mayo Clinic have shown cerebral optically-based near infrared spectroscopic oximetry applied to patients who have suffered a stroke can help monitor regional cerebral perfusion in real time. The study was using the device called Fore-Sight from Casmed of Branford, Connecticut, that measures blood oxygen, similar to a finger clip pulse oximeter. More

Study: Anemia complicates recovery after a stroke
Los Angeles Times
Being anemic could triple an individual's chances of dying in the year following a stroke, researchers say. Both anemia, which is a lack of healthy red blood cells, and stroke are common conditions among the elderly. Anemia is known to worsen the outcomes of people who have heart attacks. But a new study shows stroke patients are at higher risk.More

Hepatitis research may benefit from stem cells
Medical News Today
Hepatitis C is a viral disease that leads to inflammation and organ failure. However, researchers are puzzled as to why some individuals are susceptible to the disease while others are not. Researchers believe they could find out how genetic variations produce these different responses by investigating liver cells from different individuals in the lab.More

Mapping of Alzheimer's gives clues to stopping progression
Medical Daily
New research shows Alzheimer's disease may spread throughout brain regions by way of circuits known as synapses that link one brain cell to another. The new study, published on in the journal PloS One, raises hope that researchers may soon be able to stop Alzheimer's disease and other neurological diseases from progression. More

Could a blood test help spot depression?
HealthDay News
Depression can be a tough condition to diagnose accurately, but new research suggests that someday a blood test might help. It's not clear how much the test might cost, and it needs more stringent validation before it will be ready to be used in medical offices. More

Window installed into a live brain
Discovery News
What if we had a glass window into the brain that lets us look inside? For the first time ever, a team of physicists, chemists and biologists has done just that. Led by a microscopy pioneer, they peered into a living mouse's brain using powerful technology.More

Technique dissolves blood clots in brain, lowers brain damage risk
Bioscience Technology
Johns Hopkins neurologists report success with a way to remove potentially lethal blood clots in the brain safely without cutting through brain tissue or removing large pieces of skull. The minimally invasive treatment increased the number of patients with intracerebral hemorrhage who could function independently by 10 to 15 percent.More

Trial and tribulations of lab culture
For many grad students, postdocs, and PIs, the lab in which they work represents a type of "home away from home," replete with similar territorial issues, responsibilities and "family dynamics." And just as there are many different types of families, there are many different types of lab cultures. It may be competitive or more collaborative.More

Study: Many stroke victims don't get treated fast enough
HealthDay News via U.S. News & World Report
While a clot-busting medication can help stop a stroke if given promptly, a study finds a high number of victims fail to get to the emergency room quickly enough to get the drug. An analysis of 115,000 patients who had strokes found almost 44 percent didn't get to the hospital until more than 4.5 hours after they first showed symptoms.More

Ultrasound one step closer to a pill for men?
The Globe and Mail
New research suggests therapeutic ultrasound could one day be used to shut down sperm production, handy for men who want something more fool-proof than withdrawal or condoms, but less permanent than a vasectomy. The treatment, which is a long way from being tested on humans, involved warming the testes briefly over two sessions.More
