Association of serum and local GRP78 and CHOP expressions with disease progression in patients with non-traumatic osteonecrosis of femoral head.
J Orthop Surg Res
January 2025
Linyi People's Hospital postgraduate training base of Guangzhou University of Traditional Chinese Medicine, Linyi, Shandong, 276000, China.
Background: The endoplasmic reticulum stress (ER stress) has been involved in various musculoskeletal disorders including non-traumatic osteonecrosis of femoral head (NT-ONFH).
Objective: The current study aimed to investigate the association of glucose-regulated protein 78 (GRP78) as well as CCAAT/enhancer-binding protein homologous protein (CHOP) expressions in serum and femoral head (FH) tissues with NT-ONFH's severity.
Methods: We enrolled NT-ONFH patients (n = 150) alongside healthy controls (HCs, n = 150).
CT-sensitized nanoprobe for effective early diagnosis and treatment of pulmonary fibrosis.
J Nanobiotechnology
January 2025
Nurturing Center of Jiangsu Province for State Laboratory of AI Imaging & Interventional Radiology; Basic Medicine Research and Innovation Center of Ministry of Education, Medical School of Southeast University, 87 Dingjiaqiao, Nanjing, 210009, China.
Early diagnosis is critical for providing a timely window for effective therapy in pulmonary fibrosis (PF); however, achieving this remains a significant challenge. The distinct honeycombing patterns observed in computed tomography (CT) for the primary diagnosis of PF are typically only visible in patients with moderate to severe disease, often leading to missed opportunities for early intervention. In this study, we developed a nanoprobe designed to accumulate at fibroblastic foci and loaded with the CT sensitizer iodide to enable effective early diagnosis of PF.

BMC Ophthalmol
January 2025
Ophthalmology Unit, Queen Margaret Hospital, NHS Fife, Dunfermline, UK.
Background: COVID-19 caused a huge backlog of patients in glaucoma clinics. This study describes redesign of an entire glaucoma service with electronic patient triage to three levels and utilisation of the Scottish optometry infrastructure of upskilled optometrists.
Methods: 2276 patients in glaucoma clinics were identified and triaged to three levels in keeping with Glauc-strat-fast guidance with local amendments.
Upskilling or deskilling? Measurable role of an AI-supported training for radiology residents: a lesson from the pandemic.
Insights Imaging
January 2025
Department of Medical and Surgical Specialties, Radiological Sciences and Public Health, University of Brescia, Brescia, Italy.
Objectives: This article aims to evaluate the use and effects of an artificial intelligence system supporting a critical diagnostic task during radiology resident training, addressing a research gap in this field.
Materials And Methods: We involved eight residents evaluating 150 CXRs in three scenarios: no AI, on-demand AI, and integrated-AI. The considered task was the assessment of a multi-regional severity score of lung compromise in patients affected by COVID-19.
Bioactive hydrogel formulations for regeneration of pathological bone defects.
J Control Release
January 2025
Key Laboratory of Polymer Ecomaterials, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, 5625 Renmin Street, Changchun 130022, China. Electronic address:
Bone defects caused by osteoporosis, infection, diabetes, post-tumor resection, and nonunion often cause severe pain and markedly increase morbidity and mortality, which remains a significant challenge for orthopedic surgeons. The precise local treatments to these pathological complications is essential to avoid poor or failed bone repair. Hydrogel formulations serve as injectable innovative platforms that overcome microenvironmental obstacles and as delivery systems for controlled release of various bioactive substances to bone defects in a targeted manner.
