UA researcher’s findings on estrogen may lead to promising treatment for hot flashes

Fifteen years ago, Dr. Naomi Rance was at work when she experienced her first hot flash. Rance, a physician and researcher at the University of Arizona College of Medicine - Tucson, took note.

Adding new antibody to chemotherapy could bolster effects of cancer treatment

Adding an investigational antibody to the chemotherapy rituximab appears to restore its cancer-killing properties in certain leukemia patients with a natural resistance to the drug, according to a small, proof-of-concept study by Duke Cancer Institute researchers.

Slowing gait could be early signs of cognitive decline linked to shrinking hippocampus

The connection between slowed walking speed and declining mental acuity appears to arise in the right hippocampus, a finger-shaped region buried deep in the brain at ear-level, according to a 14-year study conducted by scientists at the University of Pittsburgh Graduate School of Public Health.

Mildly stressing muscle metabolism reverses diabetes and obesity in mice

Mildly stressing muscle metabolism boosts levels of a beneficial hormone that prevents obesity and diabetes in mice, according to a new study by researchers at the University of Iowa.

Injecting plant-based nanoparticles and chemotherapy drug helps halt tumor progression in mice

Researchers from Case Western Reserve University School of Medicine in collaboration with researchers from Dartmouth Geisel School of Medicine and RWTH Aachen University have adapted virus particles- that normally infect potatoes- to serve as cancer drug delivery devices for mice.

Radiation-exposed corals may hold new clues to keeping DNA intact

More than 70 years after the U.S. tested atomic bombs on a ring of sand in the Pacific Ocean called Bikini Atoll, Stanford researchers are studying how long-term radiation exposure there has affected corals that normally grow for centuries without developing cancer.

Wyss Institute researchers develop new capture technology for cancer diagnostics

Cancerous tumors are formidable enemies, recruiting blood vessels to aid their voracious growth, damaging nearby tissues, and deploying numerous strategies to evade the body's defense systems.

Study: Gadolinium may accumulate in brain tissues of patients without intracranial abnormalities

Minute traces of gadolinium, the contrast agent used to enhance MR images, are often retained in the brain tissue of patients years after undergoing MRI. Some studies have suggested this deposition was limited to patients with underlying brain pathology, such as a tumor or infection.

Researchers study brain region that controls addictive behavior

The human brain is nimble. It can reorganize itself to learn new things, catalog memories, and even break old habits.

Discovery of T cell exhaustion offers new pathway to more powerful immunotherapies

St. Jude Children's Research Hospital immunologists have discovered how immune cells called T cells become "exhausted" -- unable to do their jobs of attacking invaders such as cancer cells or viruses.

Researchers investigate how cystic fibrosis alters structure of mucus in airways

Mucus is important for maintaining healthy lungs. Inhaled particles, including bacteria and viruses, get trapped in mucus and then cilia -- tiny hair like projections on the surface of the airway cells -- sweep the mucus out of the airway.

DNA methylation can provide effective markers for major cancers, study reveals

In a new study, published online in the July 26 issue of PNAS, researchers at University of California San Diego School of Medicine, with colleagues in Xijing Hospital and Sun Yat-sen Cancer Center in China, report that DNA methylation can provide effective markers for at least four major cancers, not only correctly differentiating malignant tissues from normal, but also providing information on prognosis and survival.

Study finds link between upper GI infections and protein implicated in Parkinson’s disease

Acute and chronic infections in a person's upper gastrointestinal tract appear to be linked to Parkinson's disease, say scientists at Georgetown University Medical Center and their collaborators at the National Institutes of Health and other institutions.

Mouse brain models reveal insights into genetics of autism

While the definitive causes remain unclear, several genetic and environmental factors increase the likelihood of autism spectrum disorder, or ASD, a group of conditions covering a "spectrum" of symptoms, skills and levels of disability.

Multiparity improves outcomes after stroke in female mice

Stroke is an age-related disease that disproportionately affects women. Although experimental studies have identified several hormonal and genetic factors underlying these differences, little is known about how pregnancy influences risk as this has not been previously studied in the laboratory setting.

Scientists identify network of neurons that plays key role in learning vocalizations

Researchers have identified a network of neurons that plays a vital role in learning vocalizations by aiding communication between motor and auditory regions of the brain.

Mouse study uncovers key molecular player in heart enlargement

The heart is a dynamic muscle that grows and shrinks in response to stressors such as exercise and disease. The secret to its malleability lies in individual cells, which get bigger or smaller depending on the heart's needs.

New nanoallergen technology could help provide clear, accurate assessment of peanut allergies

Researchers have developed a novel platform to more accurately detect and identify the presence and severity of peanut allergies, without directly exposing patients to the allergen, according to a new study published in the journal Scientific Reports.

Researchers identify new therapy target for gonorrhea

Researchers have identified a possible new treatment for gonorrhea, using a peptide that thwarts the infection-causing bacterium by interfering with an enzyme the microbe needs to respirate.
