Researchers at the National Institute for Aging are working to improve understanding about obesity and cancer.
Researcher studies pediatric brain stem tumors
12/05/2013
Children's National researcher, Javad Nazarian, PhD, authored a new study entitled, "Comparative Multidimensional Molecular Analyses of Pediatric Diffuse Intrinsic Pontine Glioma Reveals Distinct Molecular Subtypes." The study found, for the first time, two distinct subtypes in pediatric diffuse intrinsic pontine gliomas (DIPG).
Breast cancer prognosis may be affected by mammography screening intervals
12/05/2013
In a study of screening mammography-detected breast cancers, patients who had more frequent screening mammography had a significantly lower rate of lymph node positivity - or cancer cells in the lymph nodes - as compared to women who went longer intervals between screening mammography exams.
Hope for noninvasive treatment for breast cancer using MR-guided ultrasound
12/05/2013
A technique that uses focused ultrasound under magnetic resonance (MR) guidance to heat and destroy tumors may offer a safe and effective treatment for breast cancer, according to research presented at the annual meeting of the Radiological Society of North America (RSNA).MR-guided focused ultrasound (MRgFUS) ablation is a noninvasive technique that requires no incision or puncture to perform.
New risk-scoring tool allows surgeons to better counsel and potentially change an operative plan for women at higher risk for implant failure after mastectomy, Journal of the American College of Surgeons study reports.
New way found to stabilize proteins
12/05/2013
A UConn research team has found a way to stabilize hemoglobin, the oxygen carrier protein in the blood, a discovery that could lead to the development of stable vaccines and affordable artificial blood substitutes.
New survival mechanism found for stressed mitochondria
12/05/2013
Scientists at The Scripps Research Institute (TSRI) have discovered a natural mechanism that cells use to protect mitochondria, the tiny but essential "power plants" that provide chemical energy for cells throughout the body. Damage to mitochondria is thought to be a significant factor in common neurodegenerative disorders, cancer and even the aging process.
3D mammography 'significantly increases breast cancer detection'
12/05/2013
Regular mammograms are crucial in helping to prevent deaths as a result of breast cancer. But new research from the Perelman School of Medicine at the University of Pennsylvania suggests that 3D mammography is significantly more effective for breast cancer detection and leads to fewer patient recalls.
As women age, changes in breast density relate to breast cancer risk
12/05/2013
Automated breast density measurement is predictive of breast cancer risk in younger women, and that risk may be related to the rate at which breast density changes in some women as they age, according to research presented at the annual meeting of the Radiological Society of North America (RSNA).
Breast cancer detection increased and recall rates reduced by DBT
12/05/2013
Researchers have found that digital breast tomosynthesis (DBT) led to reduced recall rates and an increase in cancer detection in a large breast cancer screening program. The results of this study were presented at the annual meeting of the Radiological Society of North America (RSNA).
