We compute the hadronic light-by-light scattering contributions to the muon anomalous magnetic moment, a μ (had), in chiral perturbation theory. We obtain the model-independent, leading and subleading logarithmic contributions to this quantity, whose sum depends on a low-energy constant entering pseudoscalar meson decay into a charged lepton pair. The uncertainty introduced by this constant is ...

The study of proteins with the same architecture, but different sequence has proven to be a valuable tool in the protein folding field. As a prelude to studies on the folding mechanism of spectrin domains we present the kinetic characterisation of the wild-type forms of the 15th, 16th, and 17th domains of chicken brain alpha-spectrin (referred to as R15, R16 and R17, respectively). We show that...

Theory predictions for g-2, the muon's anomalous magnetic moment, can be made with dispersive methods or lattice calculations, but some current estimates show tension between two. This becomes especially important in view of apparent discrepancy experimental value. The authors this Suggestion how a subset contributions to hadronic vacuum polarization, leading source theory uncertainty, related ...

Backbone-backbone hydrogen-bonding interactions are a ubiquitous and highly conserved structural feature of proteins that adopt the same fold (i.e., have the same overall backbone topology). This work addresses the question of whether or not this structural conservation is also reflected as a thermodynamic conservation. Reported here is a comparative thermodynamic analysis of backbone hydrogen ...

A large body of data exists demonstrating that neonatal Fc receptor (FcRn) binding of an IgG via its Fc CH2-CH3 interface trends with the pharmacokinetics (PK) of IgG. We have observed that PK of IgG molecules vary widely, even when they share identical Fc domains. This led us to hypothesize that domains distal from the Fc could contribute to FcRn binding and affect PK. In this study, we explor...
