      Kumar, A. A.; Patton, Matthew Reiser; Hennek, J. W.; Lee, S. Y. R.; D, G.; Yang, X.; Kanter, J.; Shevkoplyas, S. S.; Brugnara, Carlo; Whitesides, George McClelland (Proceedings of the National Academy of Sciences, 2014)
      Although effective low-cost interventions exist, child mortality attributable to sickle cell disease (SCD) remains high in low-resource areas due, in large part, to the lack of accessible diagnostic methods. The presence ...
    • Density-Based Separations in Aqueous Multiphase Systems: Tools for Biological Research and Low-Cost Diagnostics 

      Kumar, Ashok Ashwin (2014-06-06)

      Smith, Tanya; Tafforeau, P.; Reid, D. J.; Pouech, J.; Lazzari, V.; Zermeno, J. P.; Guatelli-Steinberg, D.; Olejniczak, A. J.; Hoffman, A.; Radovcic, J.; Makaremi, M.; Toussaint, M.; Stringer, C.; Hublin, J.-J. (Proceedings of the National Academy of Sciences, 2010)
      Humans have an unusual life history, with an early weaning age, long childhood, late first reproduction, short interbirth intervals, and long lifespan. In contrast, great apes wean later, reproduce earlier, and have longer ...

      Until recently, our understanding of the evolution of human growth and development derived from studies of fossil juveniles that employed extant populations for both age determination and comparison. This circular approach ...
    • Dental status and incident falls among older Japanese: a prospective cohort study 

      Yamamoto, Tatsuo; Kondo, Katsunori; Misawa, Jimpei; Hirai, Hiroshi; Nakade, Miyo; Aida, Jun; Kondo, Naoki; Kawachi, Ichiro; Hirata, Yukio (BMJ Group, 2012)
