(HealthDay)—Cerebral hypoperfusion contributes to dizziness in patients with Parkinson’s disease (PD), even without orthostatic hypotension (OH), according to a study published online April 12 in the Journal of Clinical Ultrasound. Jinse Park, M.D., from Inje University in Busan, South Korea, and colleagues conducted transcranial Doppler and blood pressure monitoring for 10 minutes during the head-up tilt...

Academia, industry collaborate on solutions to neural disease, injury
Neurological disorders like Parkinson’s, the aftermath of stroke, limb loss and paralysis significantly diminish the length and quality of life — affecting about one in six people worldwide. But a growing number of biomedical innovations, driven in large part by an aging population dealing with debilitating health issues, are improving both cognitive and motor function....

Discovery of new T-cell subtype opens window on rheumatoid arthritis
Finding flows from researchers’ use of high-tech tools to deeply and efficiently characterize patient cells Rheumatoid arthritis is an autoimmune condition in which the immune system attacks the joints, causing inflammation, pain, and eventually destruction of the tissues that make up this essential body part. A research team led by scientists from Brigham and Women’s...

Dragon blood may help wounds heal faster
A bacteria-fighting compound, based on a molecule from Komodo dragon blood, helped wounds heal faster in mice. In some myths, dragon’s blood is a toxic, vile substance. In others, it has magical properties, curing disease and making ordinary mortals invincible. When it comes to the blood of real-life Komodo dragons, both perspectives may contain a kernel...

Nanoparticle nasal spray may offer rapid and safe delivery of drugs to the brain
Traversing the blood-brain barrier is a challenge for drug developers. Now, after testing the method in locusts, a team of engineers shows how an aerosol nasal spray containing gold nanoparticles may offer a non-invasive and rapid way to deliver drugs to the brain. Researchers suggest that delivering drugs to the brain using nanoparticles in a...

New approach makes cells resistant to HIV
Scientists at The Scripps Research Institute (TSRI) have found a way to tether HIV-fighting antibodies to immune cells, creating a cell population resistant to the virus. Their experiments under lab conditions show that these resistant cells can quickly replace diseased cells, potentially curing the disease in a person with HIV. “This protection would be long term,”...

Potential new treatment to treat and stop progression of cystic fibrosis
Cystic fibrosis is a genetic disease that causes persistent lung infections and limits the ability to breathe over time. Researchers from the George Washington University (GW), the University of Perugia, and the University of Rome have discovered a potential new drug to treat and stop the progression of cystic fibrosis. Thymosin α1 (Tα1) is a...

Experimental drug turns ‘bad’ white fat into ‘good’ brown-like fat
Scientists say they know how white adipose cells — often called “bad fat” — can be converted into “good,” brown adipose in mice using little more than a synthetic stand-in for thyroid hormone. An experimental drug causes loss of weight and fat in mice, a new study has found. The study results will be presented...
