Developed by a team of researchers at Duke University in North Carolina, USA, the “gigapixel whole-body photographic camera” is essentially three dozen cameras in one, allowing the researchers to image the entire body down to a freckle. The research will be presented at The Optical Society’s (OSA) 98th Annual Meeting, Frontiers in Optics, being held Oct. 19-23 in Tucson, Arizona, USA. …
The researchers tested a new approach to detecting bone loss in cancer patients by using calcium isotope analysis to predict whether myeloma patients are at risk for developing bone lesions, a hallmark of the disease. They believe they have a promising technique that could be used to chart the progression of multiple myeloma, a lethal disease that eventually impacts a patient’s bones. The method could help tailor therapies to protect bone better and also act as a way to monitor for possible disease progression or recurrence. “Multiple myeloma is a blood cancer that can cause painful and debilitating bone lesions,” said Gwyneth Gordon, an Associate Research Scientist in ASU’s School of Earth and Space Exploration, and co-lead author of the study…
Trebananib (formally known as AMG 386; Amgen) is a first-in-class peptide-Fc fusion protein (or peptibody) that targets angiogenesis (the growth of new blood vessels into cancerous tumors) by inhibiting the binding of both angiopoietin 1 and 2 to the Tie2 receptor. This is very different mechanism of action than other agents that also effect angiogenesis by inhibiting vascular endothelial growth factor (VEGF) such as bevacizumab (Avastin; Genentech). Trebananib does not increase the risks of hypertension (high blood pressure) and bowel perforation like bevaciuzmab, but still has a similar impact on tumor shrinkage and delaying cancer progression…

Rochester researchers believe they are the first to systematically pinpoint and catalogue compassionate words and actions in doctor-patient conversations. By breaking down the dialogue and studying the context, scientists hope to create a behavioral taxonomy that will guide medical training and education. "In health care, we believe in being compassionate but the reality is that many of us have a preference for technical and biomedical issues over establishing emotional ties," said senior investigator Ronald Epstein, M.D., professor of Family Medicine, Psychiatry, Oncology, and Nursing and director of the UR Center for Communication and Disparities Research. Epstein is a national and international keynote speaker and investigator on mindfulness and communication in medical education. …
The majority of colorectal cancers arise from precursors called colorectal adenomatous polyps, or colorectal adenomas, which can be removed during a colonoscopy. Although there is extensive evidence supporting an association between higher overall levels of physical activity and reduced risk of colorectal cancer, few studies have focused on the impact of sedentary behavior on colorectal cancer risk. "Sedentary behavior is emerging as a risk factor for poor health," said Christine L…
