Covalently Immobilized Lignin–Xanthene Conjugates for Persistent Surface Photochemistry and Self‐Sterilizing Interfaces Under Ambient Visible Light

Macromolecular Rapid Communications, EarlyView.
Bio‐derived lignin–Eosin Y macromolecular networks are developed as visible‐light‐responsive self‐sterilizing coatings that generate reactive oxygen species without leaching. The spray‐coated photopolymerized surfaces exhibit durable antibacterial and antiviral activity under ambient light for extended periods, demonstrating a scalable and sustainable ...

Determination of thiocyanate in exhaled breath condensate

Free Radical Biology and Medicine, 2018
Thiocyanate is a heme peroxidase substrate that scavenges oxidants produced during inflammation and regulates host defense. In cystic fibrosis (CF) patients, increased airway thiocyanate levels are associated with improved lung function. Research on airway thiocyanate is limited, however, because convenient non-invasive airway sampling methods, such as

Voice and Speech in Atypical Parkinsonian Disorders

Movement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.
