  An octahedron of complex null rays, and conformal symmetry breaking 

  Dunajski, Maciej; Långvik, Miklos; Speziale, Simone

  We show how the manifold $T^*SU(2, 2)$ arises as a symplectic reduction from eight copies of the twistor space. Some of the constraints in the twistor space correspond to an octahedral configuration of twelve complex light ...

  B Cell Fcγ Receptor IIb Modulates Atherosclerosis in Male and Female Mice by Controlling Adaptive Germinal Center and Innate B1-Cell Responses 

  Bagchi-Chakraborty, Jayashree; Francis, Anna; Bray, Toni; Masters, Leanne; Tsiantoulas, Dimitrios; Nus, Meritxell; Harrison, JamesBroekhuizen, MichelleLeggat, JenniferClatworthy, Menna REspeli, MarionSmith, Kenneth GCBinder, Christoph JMallat, ZiadSage, Andrew et al.

  Objective— Investigate the impact of modulating B-cell FcγRIIb (Fcγ receptor IIb) expression on atherosclerosis. Approach and Results— Western diet–induced atherosclerosis was assessed in Ldlr−/− or Apoe−/− mice with ...

  HIV silencing and inducibility is heterogeneous and is affected by factors intrinsic to the virus 

  Norton, nicholas; Mok, Hoi; sharif, fatima; Hirst, jack; Lever, andrew

  Transcriptionally silent HIV proviruses form the major obstacle to eradicating HIV. Many studies of HIV latency have focused on the cellular mechanisms that maintain silencing of proviral DNA. Here we show that viral ...

  Magnetic resonance imaging is more sensitive than PET for detecting treatment-induced cell death-dependent changes in glycolysis 

  Hesketh, Richard L; Wang, Jiazheng; Wright, Alan J; Lewis, David Y; Denton, Alice E; Grenfell, Richard; Miller, Jodi LBielik, RobertGehrung, MarcelFala, MariaRos, SusanaXie, BangwenHu, De-enBrindle, Kevin et al.

  Metabolic imaging has been widely used to measure the early responses of tumors to treatment. Here we assess the abilities of positron emission tomography (PET) measurement of [18F]FDG uptake and magnetic resonance imaging ...
