Vitiligo Patients Offered New Hope With Skin Transplant
Date: Jun-01-2012Henry Ford Hospital dermatologists say skin transplant surgery is safe and effective for restoring skin pigmentation caused by the skin disease vitligo. In a first study of its kind in the United States, researchers followed 23 patients for up to six months after surgery and found that the treated area regained on average 43 percent of its natural skin color. In eight patients with localized vitiligo, the treated area regained on average 68 percent of its natural skin color...
New Guidelines To Treat Childhood Aggression
Date: Jun-01-2012Mayo Clinic researchers, in collaboration with other research institutions and youth mental health experts, are publishing new guidelines for primary care providers and mental health specialists to manage the common but often complex problem of childhood aggression. The goals include improving diagnosis and care and avoiding inappropriate use of medication. The guidelines, titled "Treatment of Maladaptive Aggression in Youth," are published online in the journal Pediatrics...
A "Life-And-Death" Molecule Identified On Chronic Leukemia Cells
Date: Jun-01-2012A new study has identified a life-and-death signaling role for a molecule on the surface of the immune cells involved in the most common form of chronic leukemia. The finding could lead to more effective therapy for chronic lymphocytic leukemia (CLL), an as yet incurable cancer that occurs in more than 16,000 Americans annually. The study, led by researchers at the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James), examines how an experimental drug called SMIP-016 kills CLL cells...
Younger Colon Cancer Patients Have Worse Prognosis At Diagnosis, Yet Better Survival
Date: Jun-01-2012Younger patients with colorectal cancer were more likely to present advanced stage tumors at diagnosis and metastasize much sooner, yet had better than or equal survival to patients 50 and older, according to data being presented at the 2012 American Society of Clinical Oncology Annual Meeting in Chicago. (Abstract #3621, Monday, June 4, 8:00 AM - 12:00 PM CST, S Hall A2). The study was led by Edith Mitchell, M.D., a clinical professor in the Department of Medical Oncology at Jefferson Medical College of Thomas Jefferson University. Dr...
Understanding How Our Senses Of Taste And Smell Work
Date: Jun-01-2012Researchers at Oregon State University have made some fundamental discoveries about how people taste, smell and detect flavor, and why they love some foods much more than others. The findings could lead to the Holy Grail of nutrition - helping people learn to really LIKE vegetables. As an evolutionary survival mechanism, humans are wired to prefer sweet-tasting foods and avoid bitter substances. In the distant past, that helped us avoid poison and find food that provided energy. Now, it just makes us fat...
Adaptation Of Yoga For Stroke Rehab
Date: Jun-01-2012Researchers looking into the value of adapted yoga for stroke rehabilitation report that after an eight-week program, study participants demonstrated improved balance and flexibility, a stronger and faster gait, and increased strength and endurance. The study, involving researchers from the Richard L. Roudebush VA Medical Center in Indianapolis, Indiana University-Purdue University Indianapolis and IU Bloomington, exposed older veterans recovering from stroke to yoga...
Nervous System Viruses Sabotage Cell, Hijack Transportation In Order To Spread
Date: Jun-01-2012Herpes and other viruses that attack the nervous system may thrive by disrupting cell function in order to hijack a neuron's internal transportation network and spread to other cells. Princeton University researchers made the first observation in neurons that common strains of the herpes virus indirectly take control of a cell's mitochondria, the mobile organelles that regulate a cell's energy supply, communication with other cells, and self-destruction response to infection...
Cutting The Death Toll From Fires Caused By Cigarettes
Date: Jun-01-2012In 2003, New York became the first state requiring cigarettes sold within its borders to pass a fire safety standard based on a test developed by the National Institute of Standards and Technology (NIST) to reduce the risk of igniting upholstered furniture and bedding, a major cause of residential fires. Last year, when Wyoming enacted a law similar to New York's, a milestone with lifesaving consequences was achieved: all 50 states had made the Standard Test Method for Measuring the Ignition Strength of Cigarettes (ASTM E2187) a regulatory requirement...
Diagnostic Biochip-Based Device Can Detect Leukemia, HIV
Date: Jun-01-2012Inexpensive, portable devices that can rapidly screen cells for leukemia or HIV may soon be possible thanks to a chip that can produce three-dimensional focusing of a stream of cells, according to researchers. "HIV is diagnosed based on counting CD4 cells," said Tony Jun Huang, associate professor of engineering science and mechanics, Penn State. "Ninety percent of the diagnoses are done using flow cytometry." Huang and his colleagues designed a mass-producible device that can focus particles or cells in a single stream and performs three different optical assessments for each cell...
Potential New HIV Vaccine/Therapy Target Identified
Date: Jun-01-2012After being infected with simian immunodeficiency virus (SIV) in a laboratory study, rhesus macaques that had more of a certain type of immune cell in their gut than others had much lower levels of the virus in their blood, and for six months after infection were better able to control the virus. SIV is a retrovirus that infects primates. Strains of SIV that crossed over to humans resulted in the evolution of HIV...
