Article Abstract
The very stable helices of 8-amino-2-quinolinecarboxylic acid oligoamides are shown to uptake Cu ions in their cavity through deprotonation of their amide functions with minimal alteration of their shape, unlike most metallo-organic structures which generally differ from their organic precursors. The outcome is the formation of intramolecular linear arrays of a defined number of Cu centers (up to sixteen in this study) at a 3 Å distance, forming a molecular mimic of a metal wire completely surrounded by an organic sheath. The helices pack in the solid state so that the arrays of Cu extend intermolecularly. Conductive-AFM and cyclic voltammetry suggest that electrons are transported throughout the metal-loaded helices in contrast with hole transport observed for analogous foldamers devoid of metal ions.

Novel hypoglossal stimulation markedly improves airflow and airway collapsibility in OSA.

Background: Hypoglossal nerve stimulation (HNS) to treat obstructive sleep apnea (OSA) currently requires placement of a cuff or 'saddle' electrode around or adjacent to the hypoglossal nerve(s). Limitations for this therapy include cost, invasiveness, and variable efficacy.
Research Question: Can HNS applied via percutaneous implantation of a linear, multi-pair electrode array restore airflow to airway narrowing and/or obstruction, and improve airway collapsibility in people with OSA?
Study Design And Methods: Participants with OSA undergoing drug induced sleep endoscopy with propofol were instrumented with an epiglottic pressure catheter, nasal mask and pneumotachograph.

An electrostatic linear ion trap (ELIT) is used to trap ions between two ion mirrors with image current detection by central detection electrode. Transformation of the time-domain signal to the frequency-domain via Fourier transform (FT) yields an ion frequency spectrum that can be converted to a mass-to-charge scale. Injection of ions into an ELIT from an external ion source leads to a time-of-flight ion separation that ultimately determines the range of over which ions can be collected from a given ion injection step.

Near-infrared (NIR) narrowband photodetectors, featuring high sensitivity, excellent wavelength selectivity, and narrow full width at half-maximum (fwhm), enable efficient detection of specific NIR wavelengths and are widely used in optical communication, environmental monitoring, spectroscopy, and scientific research. In this study, we present a self-powered NIR photodetector based on a silicon nanowire (SiNW) array, exhibiting an ultranarrowband response centered at 1120 nm. The device employs a simple Schottky junction architecture.

The WNK-OSR1/SPAK protein kinase pathway regulates ion homeostasis and cell volume, but its other functions are not well understood. To discover undefined signaling functions, we utilized experimentally-derived binding specificity to predict interactions and relative affinities with the conserved C-terminal (CCT) domains of OSR1 and SPAK, which bind short linear motifs. The upstream kinases WNKs 1-4 and their relatives, the pseudokinases NRBP1/2, also contain CCT-like domains which have conserved folds and motif binding pockets.

Tactile sensing arrays play a crucial role in human-machine interaction, robotics, and artificial intelligence by enabling the perception of physical stimuli on robotic surfaces or human skin. However, skin-attachable sensor arrays still suffer from strain interference and signal crosstalk under stretching or bending, particularly on curved or deformable surfaces. Here, we present a stretchable tactile array that is both strain-insensitive and crosstalk-suppressed, achieved via a hierarchically segmented design that mitigates lateral and vertical deformations synergistically.
