Sleep-Related Breathing Disorders and Lower Urinary Tract Dysfunction in Children and Adolescents: A Scoping Review.

Aims: Sleep disordered breathing (SDB), lower urinary tract dysfunction (LUTD), and enuresis (NE) are common in children and adolescents and have serious consequences, especially on social and emotional development. Even though much is known about the association between SDB and NE among adults, the number of articles in children and adolescents is limited. Therefore, the aim of the present scoping review was to map out the current knowledge about SDB and LUTD in children and adolescents.

De novo DNA-based catch bonds.

All primary chemical interactions weaken under mechanical stress, which imposes fundamental mechanical limits on the materials constructed from them. Biological materials combine plasticity with strength, for which nature has evolved a unique solution-catch bonds, supramolecular interactions that strengthen under tension. Biological catch bonds use force-gated conformational switches to convert weak bonds into strong ones.

SI-PET-RAFT in flow: improved control over polymer brush growth.

Surface-initiated photoinduced electron transfer-reversible addition-fragmentation chain transfer (SI-PET-RAFT) provides a light-dependent tool to synthesize polymer brushes on different surfaces that tolerates oxygen and water, and does not require a metal catalyst. Here we introduce improved control over SI-PET-RAFT polymerizations continuous flow conditions. We confirm the composition and topological structure of the brushes by X-ray photoelectron spectroscopy, ellipsometry, and AFM.

Clinical benefits and economic cost-savings of remote electrical neuromodulation (REN) for migraine prevention.

Aims: Assess the clinical benefits and associated direct and indirect cost-savings from Remote Electrical Neuromodulation (REN) for migraine prevention.

Methods: REN, a prescribed, wearable, FDA-cleared neuromodulation-device for acute and/or preventive treatment of migraine, recently demonstrated efficacy for migraine prevention when used every-other-day, in a prospective, randomized, double-blind, placebo-controlled, multi-center study. Following baseline (4-weeks), subjects underwent treatment with REN or placebo (8-weeks), and electronically reported migraine symptoms and acute treatments daily.

Single-Molecule Force Spectroscopy of a Tetraaryl Succinonitrile Mechanophore.

Fluorescent damage reporters that use mechanochemical activation of a covalent bond to elicit an optical signal are emerging tools in material mechanics as a means to access the nanoscale distribution of forces inside materials under stress. A promising class of damage reporters are tetraaryl succinonitriles (TASN), whose mechanical activation results in stable fluorescent radical species. However, in-depth insights into the molecular mechanics of TASN activation are absent, precluding their use as quantitative mechanoprobes.
