Cavoatrial Bypass for Cardiac Complications From Rosai-Dorfman Disease.

Rosai-Dorfman disease (RDD) is a nonmalignant disease of histiocyte proliferation. RDD usually presents with painless cervical lymphadenopathy, although extranodal involvement can occur. Cardiac involvement was reported in <0.

Parallel Temperature Replica-Exchange Molecular Dynamics Simulations Capture the Observed Impact of Stapling on Coiled-Coil Conformational Stability.

Macrocyclization or stapling is an important strategy for increasing the conformational stability and target-binding affinity of peptides and proteins, especially in therapeutic contexts. Atomistic simulations of such stapled peptides and proteins could help rationalize existing experimental data and provide predictive tools for the design of new stapled peptides and proteins. Standard approaches exist for incorporating nonstandard amino acids and functional groups into the force fields required for MD simulations and have been used in the context of stapling for more than a decade.

Updated Appropriate Use Criteria for Amyloid and Tau PET: A Report from the Alzheimer's Association and Society for Nuclear Medicine and Molecular Imaging Workgroup.

The Alzheimer's Association and the Society of Nuclear Medicine and Molecular Imaging convened a multidisciplinary workgroup to update appropriate use criteria (AUC) for amyloid positron emission tomography (PET) and to develop AUC for tau PET. The workgroup identified key research questions that guided a systematic literature review on clinical amyloid/tau PET. Building on this review, the workgroup developed 17 clinical scenarios in which amyloid or tau PET may be considered.
