Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

Advanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Lipopolysaccharide‐Induced Bone Loss in Rodent Models: A Systematic Review and Meta‐Analysis

Journal of Bone and Mineral Research, Volume 38, Issue 1, Page 198-213, January 2023., 2023
ABSTRACT Osteoporosis has traditionally been characterized by underlying endocrine mechanisms, though evidence indicates a role of inflammation in its pathophysiology. Lipopolysaccharide (LPS), a component of gram‐negative bacteria that reside in the intestines, can be released into circulation and stimulate the immune system, upregulating bone ...

Does fully-threaded Headless Compression Screw provide a length-stable fixation in undisplaced femoral neck fractures?

Asian Journal of Surgery, 2019
Summary: Objective: Femoral neck shortening is a common complication after surgical treatment for intracapsular femoral neck fractures. This study investigated whether fully-threaded Headless Compression Screw (FTHCS) can be a more length-stable implant

Outcomes of Hemiarthroplasty and Total Hip Arthroplasty for Femoral Neck Fracture: A Medicare Cohort Study

Journal of Orthopaedics and Trauma, 2017
Objectives: For patients with femoral neck fractures, total hip arthroplasty (THA) demonstrates superior outcomes compared with hemiarthroplasty. However, hemiarthroplasty remains a common treatment for femoral neck fractures and the conversion rates are

HU308 Mitigates Osteoarthritis by Stimulating Sox9‐Related Networks of Carbohydrate Metabolism

Journal of Bone and Mineral Research, Volume 38, Issue 1, Page 154-170, January 2023., 2023
ABSTRACT Osteoarthritis (OA) is characterized by progressive, irreversible erosion of articular cartilage accompanied by severe pain and immobility. This study aimed to assess the effect and mechanism of action of HU308, a selective cannabinoid receptor type 2 (CB2) agonist, in preventing OA‐related joint damage. To test the assumption that HU308 could

Artesunate Inhibits Neointimal Hyperplasia by Promoting IRF4 Associated Macrophage Polarization

Advanced Science, EarlyView.
This study shows that macrophage interferon regulatory factor 4 (IRF4) improved arterial injury‐induced neointimal hyperplasia by promoting of M2 polarization via up‐regulating krüppel‐like factor 4 (KLF4) in rodent and nonhuman primate models. Notably, artesunate is identified as a potent inducer of IRF4 in macrophages, and proposed as a promising ...
