They also sampled additional regions in both the human and mouse genomes, finding similar patterns along equivalent chromosomal regions, even where the underlying DNA sequences are different. Bernstein and Schreiber began to develop the analytical techniques several years earlier, working with...

Adding Radiation Therapy To Chemotherapy Improves Survival In Patients With High-risk Breast Cancer

"Our results, and those from other groups, confirm that in situations where residual disease remains, adjuvant chemotherapy alone in high-risk breast cancer patients is suboptimal and that the addition of locoregional radiation t...

They also ran experiments on deck to learn how available the iron was in the patch, how diatoms were growing and coming...
