The Pathophysiological Sequence of Glucocorticoid-Induced Osteonecrosis of the Femoral Head in Male Mice

Endocrinology, 2017
In search of the sequence of pathogenic events leading to glucocorticoid-induced osteonecrosis, we determined the molecular, biomechanical, cellular, and vascular changes in the femur of C57BL/6 mice receiving prednisolone for 14, 28, or 42 days.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

CT-Based Evaluation of Bone Mineral Density Distribution of Proximal Femur in Patients With Femoral Trochanteric Fracture

Geriatric Orthopaedic Surgery & Rehabilitation
Background Surgical treatment of proximal femoral fractures typically involves fixation with intramedullary nailing or sliding hip screws, where screws inserted into the femoral head stabilize the fracture site.
