Monte Carlo modeling of radiation dose from radiation therapy with superficial x‐rays

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Introduction Superficial x‐rays (50–100 kVp) are used for treating non‐melanoma skin cancer and intraoperative radiation therapy (IORT). At these energies, the photoelectric effect significantly increases absorbed dose to bone compared to soft tissue.

An MRI assessment of mechanisms underlying lesion growth and shrinkage in multiple sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
By applying the tensor model, we analysed lesion orientation and the directionality of lesion expansion/contraction in multiple sclerosis. Each lesion is summarized as an ellipsoid, and the tensor model is applied to calculate lesion anisotropy. From the top to the bottom white matter atlas, surface‐in gradient segmentation and venous atlas used in the

Longitudinal Trajectories of Digital Cognitive Biomarkers for Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Cognitive impairment is one of the most common and debilitating symptoms of relapsing–remitting multiple sclerosis (RRMS). Digital cognitive biomarkers require less time and resources and are rapidly gaining popularity in clinical settings.

Dual‐Phase C‐11 PiB PET Images for Detecting Tau Pathology in Cerebral Amyloid Angiopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Cerebral amyloid angiopathy (CAA) is a major cause of lobar intracerebral hemorrhage and cognitive dysfunction in the elderly, and frequently coexists with Alzheimer's disease and tau pathology. Dual‐phase 11C‐PiB PET detects amyloid deposition and cerebral perfusion changes and may have diagnostic value for identifying tau in CAA ...

Patient Perceptions of Medication Therapy for Prevention of Posttraumatic Osteoarthritis Following Anterior Cruciate Ligament Injury: A Qualitative Content Analysis

Arthritis Care &Research, EarlyView.
Objective Posttraumatic osteoarthritis (PTOA) accounts for nearly 12% of osteoarthritis incidences and often occurs after anterior cruciate ligament (ACL) tear. Ensuring the uptake of preventive treatments for PTOA requires that investigators and clinicians understand factors influencing patients to seek preventive therapies.

Graded Hydroxyapatite Triply Periodic Minimal Surface Structures for Bone Tissue Engineering Applications

Advanced Healthcare Materials, EarlyView.
This study investigates the role of triply periodic minimal structures in load bearing bone tissue engineering applications. Research uses a combination of mechanical testing, material characterization, and in vitro tests to study the impact of TPMS lattice structures (gyroid, lidinoid and split‐P).
