Their research findings, published in the journal Nature Neuroscience, have important implications for people who are affected by progressive neurodegenerative diseases, and […]

A single dose of radiotherapy is as “effective” as five doses for end-of-life cancer patients suffering with painful spinal canal compression, finds a large study conducted by UCL, including The University of Manchester. Spinal canal compression is a common complication in cancer patients when the cancer has spread to their […]

Long-term treatment with gabapentin, a commonly prescribed drug for nerve pain, could help restore upper limb function after a spinal cord injury, new research in mice suggests. In the study, mice treated with gabapentin regained roughly 60 percent of forelimb function in a skilled walking test, compared to restoration of […]

Obesity and gum (periodontal) disease are among the most common non-communicable diseases in the United States—and studies show these chronic conditions may be related. This new study explores the effect of obesity on non-surgical periodontal care and evaluates potential pathways that may illustrate the connection between the two conditions. The […]

Learned fear responses enable animals — including humans — to flee or freeze in the face of a perceived threat. But if these behaviors persist after the danger lifts, they can become paralyzing and disabling. That’s a key element of posttraumatic stress disorder (PTSD). To explore how fear becomes entrenched, […]

Aging is associated with increased inflammation and metabolic disease, including the accumulation of visceral fat — fat stored in the abdominal cavity — which is thought to contribute to inflammation. New research from University of Minnesota faculty member Christina Camell has helped uncover why visceral fat increases with age and points to […]

Women in rural communities experience higher rates of life-threatening complications during or after childbirth than mothers in urban cities, a new study finds. Maternal deaths and deliveries requiring emergency, life-saving treatment are increasing among both rural and urban residents, up from 109 to 152 per 10,000 childbirth hospitalizations, the new […]

Study on babies in Botswana provides strong evidence that early initiation of ART may benefit those who contract HIV at birth. HIV infection among infants remains an enormous global health challenge. Each day, 300 to 500 infants in sub-Saharan Africa become infected with the virus. HIV progresses much faster in […]

A new partnership between the University of Alberta and Atlas Biotechnologies will explore the use of medical cannabis for the treatment of multiple sclerosis, Alzheimer’s and Huntington’s diseases. “People are touting (cannabis) for all kinds of things, but without solid scientific evidence,” said Ross Tsuyuki, chair of the U of A’s Department […]
