Cross-Subject Seizure Detection via Unsupervised Domain-Adaptation.

Automatic seizure detection from Electroencephalography (EEG) is of great importance in aiding the diagnosis and treatment of epilepsy due to the advantages of convenience and economy. Existing seizure detection methods are usually patient-specific, the training and testing are carried out on the same patient, limiting their scalability to other patients. To address this issue, we propose a cross-subject seizure detection method via unsupervised domain adaptation.

Liquid-in-liquid printing of 3D and mechanically tunable conductive hydrogels.

Conductive hydrogels require tunable mechanical properties, high conductivity and complicated 3D structures for advanced functionality in (bio)applications. Here, we report a straightforward strategy to construct 3D conductive hydrogels by programable printing of aqueous inks rich in poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) inside of oil. In this liquid-in-liquid printing method, assemblies of PEDOT:PSS colloidal particles originating from the aqueous phase and polydimethylsiloxane surfactants from the other form an elastic film at the liquid-liquid interface, allowing trapping of the hydrogel precursor inks in the designed 3D nonequilibrium shapes for subsequent gelation and/or chemical cross-linking.

Reactive Superhydrophobic Surfaces for Interlayer Electrical Connectivity in Three-dimensional Electronics.

This study describes the development of a new type of amine-reactive superhydrophobic (RSH) film that is facilely coated on various substrates using a single-step process, while the versatility of this RSH film offers a reliable solution for efficient formation of complex and robust interlayer electrical connectivity (IEC) in 3D electronic systems. The excellent spatial controllability of surface amine modification enables the generation of vertical circuits in situ, providing a distinct way to connect circuits located on different layers. Moreover, the inherent superhydrophobicity and porosity exhibit the required anti-fouling and breathability properties, making the RSH-based IEC well-suited for applications where exposure to environmental gas and liquid contaminants is likely.

1D micro-nanopatterned integrin ligand surfaces for directed cell movement.

Cell-extracellular matrix (ECM) adhesion mediated by integrins is a highly regulated process involved in many vital cellular functions such as motility, proliferation and survival. However, the influence of lateral integrin clustering in the coordination of cell front and rear dynamics during cell migration remains unresolved.

Guiding kinetic trajectories between jammed and unjammed states in 2D colloidal nanocrystal-polymer assemblies with zwitterionic ligands.

Mesostructured matter composed of colloidal nanocrystals in solidified architectures abounds with broadly tunable catalytic, magnetic, optoelectronic, and energy storing properties. Less common are liquid-like assemblies of colloidal nanocrystals in a condensed phase, which may have different energy transduction behaviors owing to their dynamic character. Limiting investigations into dynamic colloidal nanocrystal architectures is the lack of schemes to control or redirect the tendency of the system to solidify.

Sodium Butyrate Attenuates Diarrhea in Weaned Piglets and Promotes Tight Junction Protein Expression in Colon in a GPR109A-Dependent Manner.

Background/aims: Butyric acid plays an important role in maintaining intestinal health. Butyric acid has received special attention as a short-chain fatty acid, but its role in protecting the intestinal barrier is poorly characterized. Butyric acid not only provides energy for epithelial cells but also acts as a histone deacetylase inhibitor; it is also a natural ligand for G protein-coupled receptor 109A (GPR109A).

AMP010014A09 in Sus Scrofa Encodes an Analog of G Protein-Coupled Receptor 109A, Which Mediates the Anti-Inflammatory Effects of Beta-Hydroxybutyric Acid.

Background: Hydroxy-carboxylic acid receptor 2 (HCA2, also called GPR109A) belongs to the G protein-coupled receptor (GPCR) family and is found in humans, rats, mice, hamsters and guinea pigs, but there are almost no reports of this protein in other species. In this investigation, we speculated that AMP010014A09 (AMP+) is a homologue of GPR109A in swine.

Methods: To test this hypothesis, the following experiments were designed: monocytes isolated from the peripheral blood of swine were treated with LPS after pretreating with or without β-hydroxybutyric acid (BHBA), and the levels of pro-inflammatory cytokines and inflammatory proteins were assessed.
