The Road to Commercializing Optical Metasurfaces: Current Challenges and Future Directions.

Optical metasurfaces, components composed of artificial nanostructures, are recognized for pushing boundaries of wavefront manipulation while maintaining a lightweight, compact design that surpasses conventional optics. Such advantages align with the current trends in optical systems, which demand compact communication devices and immersive holographic projectors, driving significant investment from the industry. Although interest in commercialization of optical metasurfaces has steadily grown since the initial breakthrough with diffraction-limited focusing, their practical applications have remained limited by challenges such as, massive-production yield, absence of standardized evaluation methods, and constrained design methodology.

Biofloc technology significantly reshapes water microbiome and improves survival rates in Japanese eel ().

Unlabelled: Global aquaculture production faces the challenge of biologically cycling nitrogenous waste. Biofloc technology (BFT) systems offer the potential to reduce water consumption and eliminate waste products by using beneficial microorganisms to convert waste into usable nutrients or non-toxic molecules. Unlike flow-through systems (FTS), which depend on continuous water exchange and result in higher operational costs as well as limited microbiome stability, BFT operates without the need for constant water exchange.

Identifying Disease Associated Multi-Omics Network With Mixed Graphical Models Based on Markov Random Field Model.

In this article, we proposed a new method named fused mixed graphical model (FMGM), which can infer network structures associated with dichotomous phenotypes. FMGM is based on a pairwise Markov random field model, and statistical analyses including the proposed method were conducted to find biological markers and underlying network structures of the atopic dermatitis (AD) from multiomics data of 6-month-old infants. The performance of FMGM was evaluated with simulations by using synthetic datasets of power-law networks, showing that FMGM had superior performance for identifying the differences of the networks compared to the separate inference with the previous method, causalMGM (F1-scores 0.

Cell-Interface-Deciphering Lipid Nanotablet for Nanoparticle Logic Gate-Based Real-Time Single-Cell Analysis.

Analyzing the cell interface is of paramount importance in understanding how cells interact and communicate with other cells, but an advanced analytical platform that can process complex and networked interactions between cell surface ligands and receptors is lacking. Herein, we developed the cell-interface-deciphering lipid nanotablet (CID-LNT) for multiplexed real-time cell analysis. LNT is a nanoparticle-tethered lipid bilayer chip where freely diffusing plasmonic nanoparticles induce scattering signal changes.

How Should We Use Hyaluronidase for Dissolving Hyaluronic Acid Fillers?

Background: Hyaluronic acid (HA) fillers are commonly used in esthetic medicine for facial contouring and rejuvenation. However, complications such as overcorrection, vascular occlusion, and irregular filler distribution necessitate the use of hyaluronidase to dissolve the fillers. This study aimed to evaluate the efficacy of hyaluronidase in degrading different types of HA fillers and provide clinical guidelines for its use based on filler type, dosage, and application techniques.

Mice deficient in TWIK-1 are more susceptible to kainic acid-induced seizures.

TWIK-1 belongs to the two-pore domain K (K2P) channel family, which plays an essential role in the background K conductance of cells. Despite the development of exon 2-deleted knockout (KO) mice, the physiological role of TWIK-1 has remained largely unknown. Here, we observed that the exon 2-deleted KO mice expressed an internally deleted TWIK-1 (TWIK-1 ΔEx2) protein, which unexpectedly acts as a functional K channel.

ETV2/ER71 regulates hematovascular lineage generation and vascularization through an H3K9 demethylase, KDM4A.

Effectiveness of a stepped-care programme of WHO psychological interventions in a population of migrants: results from the RESPOND randomized controlled trial.

Migrant populations - including labour migrants, undocumented migrants, asylum seekers, refugees, internationally displaced persons, and other populations on the move - are exposed to a variety of stressors that affect their mental health. We designed and tested the effectiveness of a stepped-care programme consisting of two scalable psychological interventions developed by the World Health Organization (WHO) and locally adapted for migrant populations. A parallel-group randomized controlled trial was conducted in Italy.

Controlled ligation and elongation of uniformly truncated amyloid nanofibrils.

This study investigates the production and inter-fibril interactions of uniformly truncated amyloid nanofibrils. By varying extrusion cycles (0, 50, and 100) and using carbonate filters with 100 nm and 200 nm pore sizes, precise fibril length control was achieved. Atomic force microscopy (AFM) confirmed that the mean length of the truncated fibrils corresponded to the respective pore size as extrusion cycles increased.

Optimized synthesis of biphasic calcium phosphate: enhancing bone regeneration with a tailored β-tricalcium phosphate/hydroxyapatite ratio.

Biphasic calcium phosphate (BCP) is a bioceramic widely used in hard tissue engineering for bone replacement. BCP consists of β-tricalcium phosphate (β-TCP) - a highly soluble and resorbable phase - and hydroxyapatite (HA) - a highly stable phase, creating a balance between solubility and resorption, optimally supporting cell interactions and tissue growth. The β-TCP/HA ratio significantly affects the resorption, solubility, and cellular response, with a higher β-TCP ratio increasing resorption due to its solubility.
