Peptide Receptor‐Functionalized AuNP‐Embedded Zwitterionic Biopolymeric Nanohydrogel for Electrochemical Sclerostin Sensing

Advanced Science, EarlyView.
We report an electrochemical biosensor that employs biopanning‐derived affinity peptides as selective receptors on a multifunctional chitosan–zwitterionic–gold nanoparticle (CS–ZI–AuNPs) nanohydrogel interface. The CS–ZI–AuNPs nanohydrogel exhibits antifouling properties, abundant sites for stable peptide immobilization, and efficient electrochemical ...

Romosozumab and Denosumab Combination Therapy After Denosumab in Postmenopausal Osteoporosis

Arthritis &Rheumatology, EarlyView.
Objective Transition from long‐term denosumab (Dmab) to parathyroid hormone‐analogs or romosozumab (Romo) might expose patients to the risk of the so‐called rebound phenomenon. Adding Romo to Dmab might represent an option in patients experiencing a fracture while on Dmab.

Prescribing of Medication to Prevent Glucocorticoid Harms in Patients With Polymyalgia Rheumatica: A Cross‐Sectional Study and Two Emulated Target Trials in the Clinical Practice Research Datalink Aurum

Arthritis &Rheumatology, EarlyView.
Objective Polymyalgia rheumatica (PMR) is a common indication for long‐term glucocorticoid (GC) treatment. Bone‐protective and gastroprotective medications are recommended for those at high risk of adverse events from GCs, but no trials have evaluated their effectiveness in PMR.

Biological/targeted synthetic DMARDs do not arrest bone loss in patients with rheumatoid arthritis: a long‐term multicenter observational study

Arthritis &Rheumatology, Accepted Article.
Objective Osteoporosis causes fractures which further increase the disease burden of rheumatoid arthritis (RA), however, osteoporosis treatment rates remain low. While several studies have reported that biologic or targeted synthetic disease‐modifying antirheumatic drugs (b/tsDMARDs) can prevent or improve osteoporosis in RA, our large‐scale, real ...

2D copper nanozyme patches facilitate bone regeneration via interfacial modulation of osteoclast‐osteoblast dynamics

BMEMat, EarlyView.
This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.

Move beyond free radical theory of aging

iMetaOmics, EarlyView.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central
