Precision Metal Nanoclusters Meet Proteins: Crafting Next-Gen Hybrid Materials.
ACS Nano
January 2025
Department of Chemical and Biomolecular Engineering, National University of Singapore, 4 Engineering Drive 4, Singapore 117585, Singapore.
Metal nanoclusters (NCs), owing to their atomic precision and unique molecule-like properties, have gained widespread attention for applications ranging from catalysis to bioimaging. In recent years, proteins, with their hierarchical structures and diverse functionalities, have emerged as good candidates for functionalizing metal NCs, rendering metal NC-protein conjugates with combined and even synergistically enhanced properties featured by both components. In this Perspective, we explore key questions regarding why proteins serve as complementary partners for metal NCs, the methodologies available for conjugating proteins with metal NCs, and the characterization techniques necessary to elucidate the structures and interactions within this emerging bionano system.

In light of the increasing importance for measuring myelin ratios - the ratio of axon-to-fiber (axon + myelin) diameters in myelin internodes - to understand normal physiology, disease states, repair mechanisms and myelin plasticity, there is urgent need to minimize processing and statistical artifacts in current methodologies. Many contemporary studies fall prey to a variety of artifacts, reducing study outcome robustness and slowing development of novel therapeutics. Underlying causes stem from a lack of understanding of the myelin ratio, which has persisted more than a century.

Musculoskeletal Care
March 2025
The University of Queensland's Clinical Trial Capability (ULTRA) Team, Centre for Clinical Research, The University of Queensland, Brisbane, Australia.
Objective: The burden of chronic low back pain (CLBP) is increasing rapidly along with the global population ageing. Such an increase will occur more rapidly in low- and middle-income countries (LMICs). Yet, few studies have explored the experiences of older adults with CLBP, and these are primarily conducted in high-income countries.

Laboratoire de Pharmacologie et Toxicologie, Department of Pharmacology, UR 3801, Reims University Hospital, University of Reims Champagne-Ardenne, 45 rue Cognacq Jay, 51092, Reims Cedex, France.
Background And Objective: Apixaban is increasingly being used for stroke prevention in patients with end-stage kidney disease with atrial fibrillation undergoing haemodialysis, but no pharmacostatistical model is available for dosage adjustment. This study aimed to develop a population pharmacokinetic model of apixaban in these patients to characterise its dialytic clearance and determine optimal dosing regimens and discontinuation timing before surgery.
Methods: Patients received 2.
Immunomodulatory activity of Trypanosoma cruzi recombinant antigen combination TSA-1-C4 and Tc24-C4 induce activation of macrophages and CD8 T cells.

Chagas disease is a chronic infection caused by the protozoan parasite, Trypanosoma cruzi, with limited benefits of the currently available anti-parasitic chemotherapeutic approaches to halt the progression of heart disease. Recombinant TSA-1-C4 and Tc24-C4 proteins have been developed as promising antigen candidates for therapeutic vaccines, leading to propose them in combination as a bivalent recombinant protein strategy. In this study, we evaluated the immunomodulatory effect of the combined TSA-1-C4 and Tc24-C4 recombinant proteins by in vitro assays using murine macrophages.
