Young adult self‐harm: The role of victimisation and polygenic risk in a population‐based longitudinal study

open access: yesJCPP Advances, EarlyView.
Abstract Background Victimisation has been associated with self‐harm (with or without suicidal intent), but little is known about this association during young adulthood—a distinct developmental period. Further, not all individuals who experience victimisation will later engage in self‐harm, suggesting the influence of other factors.

Proposed Diagnostic Reference Levels for Frequently Performed Paediatric Radiographic Examinations

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Paediatric diagnostic reference levels (DRLs) are weight‐stratified dose levels for typical medical imaging examinations for broadly defined types of equipment. The 75th percentiles of the FRLs across the nine X‐ray units from five centres in Australia were calculated as the proposed Local DRLs (LDRLs).

Nonresonant Surface‐Enhanced Hyper Raman Scattering of Aromatic Amino Acids on Gold Nanoparticles

open access: yesJournal of Raman Spectroscopy, EarlyView.
The surface‐enhanced hyper Raman spectra of the three aromatic amino acids phenylalanine, tryptophan, and tyrosine, obtained with nonresonant excitation at a wavelength of 1064 nm, are reported. The data are discussed in the context of the interaction of the molecules with two gold nanoparticle plasmonic substrates, as well as intermolecular ...

Nonlinear Resonance Modulation in Single‐Crystalline VO2‐Integrated Si Ring Resonator

open access: yesLaser &Photonics Reviews, EarlyView.
This work first demonstrates a single‐crystalline VO2–Si hybrid ring resonator. The epitaxial lift‐off process enables high‐quality VO2 integration on the dissimilar Si photonic platform. The high‐quality VO2 film exhibits exceptional nonlinear resonance modulation and a steep optical transition across the metal‐insulator transition. ABSTRACT The metal‐

Parkinson's Disease Patient‐Specific Striatum Organoids Show Hallmarks of Increased Inflammation

open access: yesMovement Disorders, EarlyView.
Abstract Background Dopaminergic neurons from the substantia nigra pars compacta project their axons into the dorsal striatum, forming the nigrostriatal pathway. In Parkinson's disease (PD), dopaminergic terminals degenerate in the striatum, leading to dopamine depletion, which in turn causes alterations in the basal ganglia circuits that are essential

Biodegradable Natural Polymer‐Based Drug Delivery Systems for Bone Tissue Engineering

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT The increasing incidence of bone diseases and injuries, especially among aging populations, has underscored the shortcomings of traditional treatments such as bone grafts and metal implants, which often face complications including immune rejection, mechanical failure, and delayed healing.
