First record of the family Calliopiidae (Crustacea, Malacostraca, Amphipoda) from Korean waters, with description of new species sp. nov.

A new species of the family Calliopiidae was collected from the East Sea of Korea. is similar to Bousfield & Hendrycks, 1997 in having numerous calceoli on the posteromedial margins of antennae and a weakly carinate body. However, the new species can be distinguished from by the shorter process on peduncular article 3 of antenna 1, subrectangular eyes, and fewer articles in the antenna flagellum.

Effective Spiral Laser Path for Minimizing Local Heating and Anisotropic Microstructures in Powder Bed Fusion Additive Manufacturing.

Heat accumulation due to repetitive simple laser processing paths during building up a three-dimensional structure is a well-known issue that needs to be settled to reduce the excessively high residual stress and thermal deformation in a powder bed fusion (PBF) additive manufacturing process. Because of the dependency of laser path on the thermal dispersion, it is essential to analyze the heat accumulation phenomenon during laser processing. A computational fluid dynamics (CFD) analysis based on the volume of fraction method is used to optimize the laser path for minimizing the local heating up in the PBF process.

The effects of filter fabrication approaches on photocatalytic abatement of formaldehyde in an indoor environment using a TiO-based air purifier system.

Titanium dioxide (TiO) is the most commonly used catalyst for fabricating commercial photocatalytic air purifier (AP) systems. The AP performance can be affected sensitively by the preparation conditions of filters and the physicochemical properties (e.g.

Neurotoxic effects of citronellol induced by the conversion of kynurenine to 3-hydroxykynurenine.

Citronellol is widely utilized in consumer products, including cosmetics, fragrances, and household items. However, despite being considered a relatively safe chemical, the health effects and toxicity mechanisms associated with exposure to high concentrations of citronellol, based on product content, remain inadequately understood. Here, we aimed to analyze the neurological effects of citronellol in zebrafish larvae using behavioral and histological analyses and elucidate the mechanisms underlying its neurotoxicity in vivo.

Signaling pathways of duck RIG-I in gene-edited DF1 chicken cells.

Retinoic acid inducible gene I (RIG-I) is an innate immune RNA sensor which can detect viral infection such as influenza viruses. Duck but not chicken has an RIG-I gene. However, the immune responses could be induced in chicken cells by transferring the duck RIG-I transgene.
