Radium Speciation in Simulated Digestive Biofluids: Insights from Electrospray Ionization Mass Spectrometry and Thermodynamic Modeling

Analysis &Sensing, EarlyView.
Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.

Argon Cold Plasma Modification of Polyethylene Films to Tailor Surface and Barrier Properties

Journal of Applied Polymer Science, EarlyView.
Argon cold plasma treatment of low‐density polyethylene (LDPE) and high‐density polyethylene (HDPE) films induces major changes in surface chemistry and morphology. Contact angles decrease significantly while surface energy increases, improving wettability. FTIR confirms the formation of polar functional groups, while pronounced etching, roughness, and

Autoantibody Response Toward Chromatin in Patients With Juvenile Idiopathic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Patients with juvenile idiopathic arthritis (JIA) frequently exhibit antinuclear antibodies (ANAs), but the specific antigen target recognized by them and the presence of additional autoantibody specificities in patients with JIA remains elusive.

Optimizing Measurement of Communication in Autistic Children and Their Caregivers: Dependability of the Caregiver‐Child Interaction

Autism Research, EarlyView.
ABSTRACT Despite widespread use of caregiver‐child interactions (CCX) to evaluate outcomes in autism interventions, little research has examined the dependability of this measure. This study applied generalizability theory to determine optimal conditions for dependable assessment of child communication and caregiver implementation of communication ...
