Researchers identify biochemical factors that may predict Alzheimer's disease

Investigators have wondered why the brains of some cognitively-intact elderly individuals have abundant pathology on autopsy or significant amyloid deposition on neuroimaging that are characteristic of Alzheimer disease (AD).

Bern study sheds light on the brain mechanism of arousal

Scientists from Bern have discovered a mechanism which is responsible for the rapid arousal from sleep and anesthesia in the brain. The results of their study suggest new strategies for the medical treatment of sleep disorders and recovery of consciousness in vegetative states.

Commonly used diabetes drug may have potential to prevent, treat preeclampsia

An article published today in the American Journal of Obstetrics and Gynecology reports that a commonly-used drug for the treatment of diabetes, metformin, may have the potential to prevent and treat preeclampsia. Metformin has long been used to treat diabetes in both non-pregnant and pregnant patients, and is considered safe during pregnancy.

Pelvic pain linked to poor mental health outcomes among women with endometriosis

A new study published in the Journal of Psychosomatic Obstetrics & Gynecology has found that women who suffer from pelvic pain caused by endometriosis may need psychological intervention in order to help improve their mental health and quality of life.

Large doses of vitamin A reduce severity of gastrointestinal disease in mice

After observing that some gastrointestinal disease in premature human and mouse infants progresses only when certain immune system white blood cells go into inflammatory overdrive, Johns Hopkins researchers have found that giving large doses of vitamin A to mice converts those blood cells into inflammation suppressors and reduces the severity of the disease, compared to untreated mice.

Wnt5a protein acts on tumor-surface proteins to accelerate spread of CLL cells

Building upon previous research, scientists at University of California, San Diego School of Medicine and UC San Diego Moores Cancer report that a protein called Wnt5a acts on a pair of tumor-surface proteins, called ROR1 and ROR2, to accelerate the proliferation and spread of chronic lymphocytic leukemia (CLL) cells, the most common form of blood cancer in adults.

Crackdown on Florida's 'pill mills' reduces painkiller overdose deaths

A crackdown on Florida's "pill mills" - clinics dispensing large quantities of prescription painkillers often for cash-only and without proper medical examinations - appears to have dramatically reduced the number of overdose deaths in the state from these drugs and may have also led to a drop in heroin overdose deaths, new research suggests.

New treatment strategy may take pain away

A brain region controlling whether we feel happy or sad, as well as addiction, is remodeled by chronic pain, reports a new Northwestern Medicine study.

Family-level preventive intervention may improve outcomes for military families affected by wartime deployment

Family-level preventive intervention can lead to improved behavioral health outcomes for military families affected by wartime deployment, a new study published in the January 2016 issue of the Journal of the American Academy of Child and Adolescent Psychiatry reports.

New study examines single 'transformer' proteins involved in cancer

A new study led by scientists at The Scripps Research Institute and St. Jude Children's Research Hospital shows how a protein involved in cancer twists and morphs into different structures.

Small price differences highly effective in shifting consumer demand to healthy low calorie alternatives

Small price differences at the point of purchase can be highly effective in shifting consumer demand from high calorie to healthier low calorie alternatives, according to a study in the Articles in Advance section of Marketing Science, a journal of the Institute for Operations Research and the Management Sciences.

New MRI-based technology could help identify patients at risk of recurrent stroke

Patients who have had a stroke in the back of the brain are at greater risk of having another within two years if blood flow to the region is diminished, according to results of a multicenter study led by researchers at the University of Illinois at Chicago.

Study reveals new genetic factors linked to age-related macular degeneration

An international study of about 43,000 people has significantly expanded the number of genetic factors known to play a role in age-related macular degeneration (AMD), a leading cause of vision loss among people age 50 and older.

MD Anderson study reveals MDSCs as likely target for developing prostate cancer treatments

Immune suppressor cells called MDSCs (myeloid-derived suppressor cells) may be important in developing treatments for advanced prostate cancer, according to a study at The University of Texas MD Anderson Cancer Center.

Scientists identify 52 genetic variations associated with age-related macular degeneration

In one of the latest examples of precision medicine, teams of geneticists from nine countries, involving more than 100 scientists, analyzed the genes of more than 33,000 individuals in the hope of finding genetic variations responsible for age-related macular degeneration (AMD), the leading cause of vision loss among people age 50 or older.

Immunotherapy more effective than chemotherapy in treating patients with advanced lung cancer

A new study has found immunotherapy to be more effective than chemotherapy in treating most previously treated patients with advanced lung cancer, and demonstrated effectiveness in a wider population of people than previously known to benefit from the therapy.

Excess body fat may affect bone growth in children

Studies have shown that obese children tend to have more muscle, but recent University of Georgia research on the muscle and bone relationship shows that excess body fat may compromise other functions in their bodies, such as bone growth.

Drug that boosts activity in the brain's 'garbage disposal' system may slow Alzheimer's disease

A drug that boosts activity in the brain's "garbage disposal" system can decrease levels of toxic proteins associated with Alzheimer's disease and other neurodegenerative disorders and improve cognition in mice, a new study by neuroscientists at Columbia University Medical Center has found.
