The Restriction Spectrum Imaging restriction score (RSIrs) has been shown to improve the accuracy for diagnosis of clinically significant prostate cancer (csPCa) compared to standard DWI. Both diffusion and T properties of prostate tissue contribute to the signal measured in DWI, and studies have demonstrated that each may be valuable for distinguishing csPCa from benign tissue. The purpose of this retrospective study was to (1) determine whether prostate T varies across RSI compartments and in the presence of csPCa, and (2) evaluate whether csPCa detection with RSIrs is improved by acquiring multiple scans at different TEs to measure compartmental T (cT).

Achilles tendon ruptures are prevalent among physically active adults and can lead to sural nerve injuries (SNIs) due to the anatomical proximity of the sural nerve to the Achilles tendon. While SNIs are well-recognized in surgical contexts, their occurrence following nonoperative treatments, which are often preferred for their lower risk of surgical complications, remains less documented and poorly understood. This report describes a case of a 30-year-old active male who developed chronic traction sural neuropathy after opting for nonoperative treatment of an acute complete Achilles tendon rupture.

Biological cells rely on precise spatiotemporal coordination of biochemical reactions to control their functions. Such cell signaling networks have been a common focus for mathematical models, but they remain challenging to simulate, particularly in realistic cell geometries. Here we present Spatial Modeling Algorithms for Reactions and Transport (SMART), a software package that takes in high-level user specifications about cell signaling networks and then assembles and solves the associated mathematical systems.

IP6, PF74 affect HIV-1 capsid stability through modulation of hexamer-hexamer tilt angle preference.

Biophys J

December 2024

Department of Integrative Structural and Computational Biology, The Scripps Research Institute, La Jolla, California. Electronic address:

The HIV-1 capsid is an irregularly shaped protein complex containing the viral genome and several proteins needed for integration into the host cell genome. Small molecules, such as the drug-like compound PF-3450074 (PF74) and the anionic sugar inositolhexakisphosphate (IP6), are known to impact capsid stability, although the mechanisms through which they do so remain unknown. In this study, we employed atomistic molecular dynamics simulations to study the impact of molecules bound to hexamers at the central pore (IP6) and the FG-binding site (PF74) on the interface between capsid oligomers.

Objectives: Social and structural determinants of health (SSDoH) have been linked to racial disparities in Alzheimer's disease and related dementias (ADRD). Research has established that living in an environment with greater economic stability (ES) or health care access (HCA) is associated with better baseline cognition, but the interactive effects between these distinct SSDoH on cognition over time have not been studied. Therefore, the present study examined the independent and interactive effects of ES and HCA on 10-year change in cognitive functioning within a large sample of racially diverse community-dwelling older adults.

Background: Accessing opioid use disorder (OUD) treatment is difficult for individuals in unstable housing. This population often uses public libraries for computer and internet access, which could provide telehealth access to OUD treatment. Therefore, we developed a novel 12-week library-facilitated telehealth intervention study called "Bupe by the Book" (BBB), which uses library resources to facilitate the initiation and retention of OUD treatment with buprenorphine.

Purpose: Automated retinal cell layer segmentation empowers OCT as a precise tool for characterizing morphologic features of retinal health throughout age-related macular degeneration (AMD) progression, particularly in advance of more visible biomarkers such as drusen and macular pigmentary changes. Few studies have examined OCT changes in eyes progressing from early to intermediate disease, or combined examinations of cell layer thickness, reflectivity, and heterogeneity. Therefore, this study analyzed OCTs from eyes progressing from early to intermediate AMD to identify changes in retinal morphology and reflectivity that may serve as biomarkers of early progression.
