    • Kickoff to Conflict: A Sequence Analysis of Intra-State Conflict-Preceding Event Structures 

      D'Orazio, Vito; Yonamine, James E. (Public Library of Science, 2015)
      While many studies have suggested or assumed that the periods preceding the onset of intra-state conflict are similar across time and space, few have empirically tested this proposition. Using the Integrated Crisis Early ...

    • Kidneys For Sale: Who Disapproves, and Why? 

      Leider, Stephen; Roth, Alvin E. (Wiley-Blackwell, 2010)
      The shortage of transplant kidneys has spurred debate about legalizing monetary payments to donors to increase the number of available kidneys. However, buying and selling organs faces widespread disapproval. We survey a ...

      Purpose: Two Chinese families (XT and YT) with congenital fibrosis of the extraocular muscles (CFEOM) were identified. The purpose of this study was to determine if previously described Homo sapiens kinesin family member ...

    • Killer Cell Immunoglobulin-Like Receptor Alleles Alter HIV Disease in Children 

      Singh, Kumud K.; Qin, Min; Brummel, Sean S.; Angelidou, Konstantia; Trout, Rodney N.; Fenton, Terence; Spector, Stephen A. (Public Library of Science, 2016)
      Background: HLA class I molecules are ligands for killer cell immunoglobin like receptors (KIR) that control the antiviral response of natural killer (NK) cells. However, the effects of KIR and HLA (KIR/HLA) alleles on HIV ...

    • The Killer Precedent for Today's Decision 

      Elhauge, Einer Richard (New Republic, 2012)

    • killerFLIP: a novel lytic peptide specifically inducing cancer cell death 

      Pennarun, B; Gaidos, G; Bucur, O; Tinari, A; Rupasinghe, C; Jin, T; Dewar, R; Song, K; Santos, M T; Malorni, W; Mierke, D; Khosravi-Far, R (Nature Publishing Group, 2013)
      One of the objectives in the development of effective cancer therapy is induction of tumor-selective cell death. Toward this end, we have identified a small peptide that, when introduced into cells via a TAT cell-delivery ...

    • Killing of Caenorhabditis elegans by Cryptococcus neoformans as a model of yeast pathogenesis 

      Mylonakis, Eleftherios; Ausubel, Frederick M.; Perfect, John R.; Heitman, Joseph; Calderwood, Stephen B. (National Academy of Sciences, 2002)
      We found that the well-studied nematode Caenorhabditis elegans can use various yeasts, including Cryptococcus laurentii and Cryptococcus kuetzingii, as a sole source of food, producing similar brood sizes compared with ...
