A Sensitive Method to Quantify Senescent Cancer Cells Julie Cahu1, Brigitte Sola1 1MILPAT (EA 4652), Université de Caen Basse-Normandie Whether senescence prevents or promotes tumorigenesis remains controversial. Since chemotherapeutical drugs can induce cancer cells to senesce, studying senescence is essential for proposing new therapies. However, the standard and broadly used β-galactosidase assay presents major drawbacks. We propose here a rapid and sensitive flow cytometry-based assay to quantify senescence.
Non-invasive Optical Measurement of Cerebral Metabolism and Hemodynamics in Infants Pei-Yi Lin1, Nadege Roche-Labarbe1,2, Mathieu Dehaes3, Stefan Carp1, Angela Fenoglio3, Beniamino Barbieri4, Katherine Hagan1, P. Ellen Grant3, Maria Angela Franceschini1 1Athinoula A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Harvard Medical School, 2Lab. PALM, Université de Caen Basse-Normandie, 3Fetal-Neonatal Neuroimaging and Developmental Science Center, Boston Children's Hospital, Harvard Medical School, 4ISS, INC. We combined frequency-domain near-infrared spectroscopy measures of cerebral hemoglobin oxygenation with diffuse correlation spectroscopy measures of cerebral blood flow index to estimate an index of oxygen metabolism. We tested the utility of this measure as a bedside screening tool to evaluate the health and development of the newborn brain.
