Failure of the molecular bodyguard in Parkinson’s disease

Scientists from ETH Zurich and the University of Basel’s Biozentrum have shown that chaperone proteins dynamically bind to the Parkinson protein α-​synuclein. If this interaction is disturbed, it leads to cell damage and the formation of aggregates typical for the disease. Parkinson’s disease is characterized by the progressive death of […]

One dose of radiotherapy as effective as five doses for cancer in the spine

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 […]

A common drug could help restore limb function after spinal cord injury

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 […]

New study explores the link between obesity and gum disease

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 […]

Study finds ‘frozen’ fear response may underlie PTSD

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, […]

Research Brief: Study shows why visceral fat increases with age and impairs metabolism

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 […]
