Background: Longitudinal cohort studies have traditionally relied on clinic-based recruitment models, which limit cohort diversity and the generalizability of research outcomes. Digital research platforms can be used to increase participant access, improve study engagement, streamline data collection, and increase data quality; however, the efficacy and sustainability of digitally enabled studies rely heavily on the design, implementation, and management of the digital platform being used.

Objective: We sought to design and build a secure, privacy-preserving, validated, participant-centric digital health research platform (DHRP) to recruit and enroll participants, collect multimodal data, and engage participants from diverse backgrounds in the National Institutes of Health's (NIH) All of Us Research Program (AOU).

Giant cell tumors (GCTs) are benign but locally aggressive bone neoplasms that primarily affect skeletally mature individuals. They are characterized by a tendency for recurrence and being associated with significant morbidity. Traditional treatment has focused on surgical resection; however, the role of medical therapies, such as Denosumab, a bone anti-resorptive drug, which has been Food and Drug Administration (FDA)-approved for unresectable GCTs since 2013, recently has gained prominence.

ZFAND6 is a zinc finger protein that interacts with TNF receptor-associated factor 2 (TRAF2) and polyubiquitin chains and has been linked to tumor necrosis factor (TNF) signaling. Here, we report a previously undescribed function of ZFAND6 in maintaining mitochondrial homeostasis by promoting mitophagy. Deletion of ZFAND6 in bone marrow-derived macrophages (BMDMs) upregulates reactive oxygen species (ROS) and the accumulation of damaged mitochondria due to impaired mitophagy.

Purpose: In locations where the proton energy spectrum is broad, lineal energy spectrum-based proton biological effects models may be more accurate than dose-averaged linear energy transfer (LET) based models. However, the development of microdosimetric spectrum-based biological effects models is hampered by the extreme computational difficulty of calculating microdosimetric spectra. Given a precomputed library of lineal energy spectra for monoenergetic protons, a weighted summation can be performed which yields the lineal energy spectrum of an arbitrary polyenergetic beam.

Rigidity Aspects of Penrose's Singularity Theorem.

Commun Math Phys

January 2025

Copenhagen Centre for Geometry and Topology (GeoTop), Department of Mathematical Sciences, University of Copenhagen, Copenhagen, Denmark.

In this paper, we study rigidity aspects of Penrose's singularity theorem. Specifically, we aim to answer the following question: if a spacetime satisfies the hypotheses of Penrose's singularity theorem except with weakly trapped surfaces instead of trapped surfaces, then what can be said about the global spacetime structure if the spacetime is null geodesically complete? In this setting, we show that we obtain a foliation of MOTS which generate totally geodesic null hypersurfaces. Depending on our starting assumptions, we obtain either local or global rigidity results.
