Dr. John S. Kuo and colleagues of University of Wisconsin School of Medicine and Public Health, Madison, evaluated two “tumor-selective” fluorescent agents — called CLR1501 and CLR1502 — for their ability to differentiate brain tumors from normal brain tissue in mice…
“It’s really all about natural selection and survival of the fittest,” says James DeGregori, PhD, investigator at the CU Cancer Center, professor of Biochemistry and Molecular Genetics at the CU School of Medicine, and the paper’s senior author. “When you’re young, healthy cells are optimized to the surrounding tissue — they’re the ‘fittest’,” DeGregori says. …
The study, “Volumetric Breast Density Improves Breast Cancer Risk Prediction,” was presented during the 2014 San Antonio Breast Cancer Symposium. “There is increasing interest in implementing personalized breast cancer screening strategies instead of guidelines based on a woman’s age. However, most risk models do not include breast density, which is an important indicator of a woman’s breast cancer risk,” said Jennifer Harvey, MD, professor of radiology at the UVA School of Medicine…
“We found that adding either carboplatin or bevacizumab to standard preoperative chemotherapy increased pathologic complete response rates for women with basal-like cancers — that is, it increased the proportion of women who had no residual cancer detected at surgery. At the same time, we found that while carboplatin had a similar effect in the smaller group of triple-negative patients with nonbasal-like cancers, adding bevacizumab actually decreased response rates for women with nonbasal-like cancers,” says William M. Sikov, MD, associate chief of clinical research with the Program in Women’s Oncology at Women & Infants and associate professor of medicine at The Warren Alpert Medical School of Brown University…
“Hypofractionated radiation is infrequently used for women with early-stage breast cancer, even though it’s high-quality, patient-centric cancer care at lower cost,” said lead author Bekelman, an assistant professor of Radiation Oncology, Medical Ethics and Health Policy at the University of Pennsylvania’s Perelman School of Medicine and Abramson Cancer Center. “It is clinically equivalent to longer duration radiation in curing breast cancer, has similar side effects, is more convenient for patients, and allows patients to return to work or home sooner.” Shown to reduce local recurrence and improve overall survival after breast conserving surgery, conventional whole breast radiation, given daily over five to seven weeks, has been the mainstay of treatment in the U.S. for women for decades…

“A comprehensive geriatric assessment of elderly patients who are being evaluated for the Whipple procedure is essential,” said lead study author Dominic Sanford, MD, MPHS, a general surgery resident at the Washington University School of Medicine, St. …
According to researchers from the Joslin Diabetes Center and the Department of Medicine at Harvard Medical School, “Since insulin resistance alters the metabolic status in the affected individuals, its presence in women during pregnancy has the potential to be detrimental to growth and metabolism in the offspring. Thus, insulin resistance directly impacts pregnant women and also their offspring.” The research team — which included Sevim Kahraman, Ercument Dirice, Dario DeJesus, Jiang Hu and Rohit Kulkarni — used a mouse model of insulin resistance to find out how it affects metabolism and endocrine pancreas development in the offspring. Insulin is a hormone created in the beta cells (β-cells) of the pancreas. …
Researchers from Royal Holloway, University of London, together with an international team from across the United States and Europe, have found that people with a specific variant of a gene, known as PHACTR1, are at reduced risk of suffering cervical artery dissection, which is caused by a tear in an artery that leads to the brain. The new discovery, published in the journal Nature Genetics, could lead to new treatments and prevention strategies for the disease, which is a major cause of stroke in young adults. The same gene variant has also been identified as a protector against migraines and affects the risk of heart attack. Professor Pankaj Sharma, from the School of Biological Sciences at Royal Holloway, said: “This is an important breakthrough…
