Scientists 'watch' as individual alpha-synuclein proteins change shape

In an Early Edition publication of The Proceedings of the National Academy of Sciences (PNAS) this week, the researchers demonstrate the "alpha-synuclein dance" - the switching back and forth of the protein between a bent helix and an extended helix as the surface that it is binding to changes.

Risks of using aspirin to prevent heart attack or stroke differ by gender and age

Patients and clinicians should consider risk factors-- including age, gender, diabetes, blood pressure, cholesterol levels, smoking and risk of gastrointestinal bleeding-- before deciding whether to use aspirin to prevent heart attacks or strokes, according to new recommendations from the U.S. Preventive Services Task Force.

Identification of triggering mechanism by which breast and prostate cancer cells begin

Dr. Ercole Cavalieri and Dr. Eleanor Rogen of the University of Nebraska Medical Center, Eppley Institute for Research in Cancer, located in Omaha, Nebraska, have identified the triggering mechanism by which breast and prostate cancer cells begin. Preventium is a recently developed dietary supplement that promises to reduce people's risk for breast and prostate cancer.

Obesity brings worse outcomes after pancreatic cancer surgery

Obese patients with a body mass index (BMI) of more than 35 appear more likely to have cancer that has spread to their lymph nodes, lower rates of survival and higher rates of recurrence following surgery for pancreatic cancer, according to a report in the March issue of Archives of Surgery, one of the JAMA/Archives journals.
