Novel treatment safe and effective for patients with intracerebral hemorrhage

A new treatment that treats a subset of stroke patients by combining minimally invasive surgery, an imaging technique likened to "GPS for the brain," and the clot-busting drug t-PA appears to be safe and effective, according to a multicenter clinical trial led by Johns Hopkins researchers.

Scientists discover protein involved in nerve cell motor-cargo mechanism

With every bodily movement-from the blink of an eye to running a marathon-nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers that excite muscles cells into action. It's a complex process, which scientists are still trying to understand. A new study by Syracuse University researchers has uncovered an important piece of the puzzle.

Exposure to common fire retardant may cause developmental malformations, behavioral changes and death

A new study by Baylor University environmental health researchers found that zebra fish exposed to several different technical mixtures of polybrominated diphenyl ethers (PBDEs) - a common fire retardant - during early development can cause developmental malformations, changes in behavior and death.

MRSA, VRE traces found in bed bugs

Reports of bed bug infestations are on the rise worldwide. Recently, scientists in Canada studying five bed bugs found on patients at St. Paul's Hospital, found traces of methicillin-resistant Staphylococcus aureus, or MRSA, and vancomycin-resistant Enterococcus faecium, or VRE. However as of yet, no evidence indicating that bed bugs can transmit disease to humans has been found.

'Survival protein' protects brain against effects of stroke

Johns Hopkins scientists say that a newly discovered "survival protein" protects the brain against the effects of stroke in rodent brain tissue by interfering with a particular kind of cell death that's also implicated in complications from diabetes and heart attack.

Scientists direct embryonic, induced human stem cells to become astrocytes in lab dish

Pity the lowly astrocyte, the most common cell in the human nervous system. Long considered to be little more than putty in the brain and spinal cord, the star-shaped astrocyte has found new respect among neuroscientists who have begun to recognize its many functions in the brain, not to mention its role in a range of disorders of the central nervous system.

Many 'legal high' drugs sold on the internet do not contain ingredients they claim

Many drugs sold as 'legal highs' on the internet do not contain the ingredients they claim. Some instead contain controlled substances and are illegal to sell over the internet. These are findings of Dr. Mark Baron, who bought a range of tablets from different websites to see what each contained. The study is published today in the journal Drug Testing and Analysis.

Study shows why individuals with anorexia nervosa have paradoxical response to food

Perhaps the most puzzling symptom of anorexia nervosa - a disorder that tends to occur in young women - is the refusal to eat, resulting in extreme weight loss. While most people have a great deal of difficulty in dieting and losing weight, particularly if a diet extends over many months or years, individuals with anorexia nervosa can literally diet themselves to death. In fact, this disorder has a very high death rate from starvation.

Serpin-2 molecule may be a perfect target for preventing mosquito's immunity

Mosquitoes are becoming more resistant to current pesticides. That's troubling to Kansas State University biologist Kristin Michel, as it means malaria and other mosquito-borne diseases will continue spreading. A recent grant from the National Institutes of Health may change all that.
