Misfolded neurotoxic proteins, such as Tau protein, spread within the brain in many neurodegenerative diseases. Receptors play an important role in the recognition of spreading proteins for endocytosis. Blocking the receptors is essential to inhibit neurotoxic proteins spreading in the brain.

DNA and RNA markers are significant in forensic practices, such as individual and body fluid identification. However, forensic DNA and RNA markers were separately analyzed in most forensic experiments, which resulted in large amounts of sample consumption, complex procedures, and weak inter-evidence correlation. While several integrated methods based on capillary electrophoresis and next-generation sequencing technologies were reported, integrated procedures were mostly on nucleic acid co-extraction, co-electrophoresis, or co-sequencing, and the number and type of markers co-tested were limited.

Label-free surface-enhanced Raman spectroscopy (SERS) combined with machine learning (ML) techniques presents a promising approach for rapid pathogen identification. Previous studies have demonstrated that purine degradation metabolites are the primary contributors to SERS spectra; however, generating these distinguishable spectra typically requires a long incubation time (>10 h) at room temperature. Moreover, the lack of attention to spectral variations between strains of the same bacterial species has limited the generalizability of ML models in real-world applications.

Hand osteoarthritis (HOA) is a heterogeneous joint disease with high radiographic and symptomatic prevalence. The diagnosis of HOA is based on clinical and radiographic features. The identification of potential biomarkers for diagnosis, prognosis, disease severity assessment, and therapeutic efficacy evaluation of НОА remains an active area of research.
