On the genus Lyphira Galil, 2009 (Crustacea: Brachyura: Leucosiidae), with descriptions of four new species from the West Pacific.

The taxonomy of the shallow water leucosiid crab, Lyphira heterograna (Ortmann, 1892), is revised on the basis of the lectotype and material from Japan, southern China, Hong Kong and Southeast Asia previously identified with this species. Six species are now recognised in the Lyphira heterograna species-group, of which four are new species: L. chomel n.

Description of a new genus and new species of freshwater crab (Crustacea, Decapoda, Potamidae) from Yunnan, China.

A new genus and new species of freshwater crab is described from Yunnan Province, China. Proboscimon keeae gen. n.

A new species of Ducetia (Tettigoniidae, Phaneropterinae) from Mindanao, Philippines based on bioacoustics, stridulatory file morphology and genetic data.

The Ducetia japonica species group consists of 11 species widely distributed in Asia and Australia. It includes a single species from the Philippines: Ducetia adspersa Brunner von Wattenwyl, 1878. Previously synonymized under Ducetia japonica (Thunberg, 1815), this species was resurrected for its unique stridulatory file.

Chronic Exposure of Adult Zebrafish to Polyethylene and Polyester-based Microplastics: Metabolomic and Gut Microbiome Alterations Reflecting Dysbiosis and Resilience.

The study explored the ecotoxicological effects of chronic exposure to microplastic (MP) on adult zebrafish, focusing on environmentally relevant concentrations of polyethylene (PE) beads and polyester (PES). High-throughput untargeted metabolomics via UPLC-QToF-MS and 16S metagenomics for gut microbiota analysis were used to assess ecotoxicity in zebrafish exposed to varying concentrations of PE and PES. The VIP (Variable Importance in Projection) scores indicated PE exposure primarily impacted phospholipids, ceramides, and nucleotide-related compounds, while PES exposure led to alterations in lipid-related compounds, chitin, and amino acid derivatives.

Removing immunogenic double-stranded RNA impurities post in vitro transcription synthesis for mRNA therapeutics production: A review of chromatography strategies.

Messenger RNA (mRNA) vaccines and therapeutics hold immense potential for a wide range of clinical applications. However, the in vitro transcription (IVT) process used to synthesize mRNA also results in the generation of a by-product, double-stranded RNA (dsRNA), which can trigger innate immune activation and reduce translation activity. Although various efforts have been made to optimize IVT synthesis to minimize dsRNA formation, dsRNA impurities still cannot be fully resolved.

Atomically Dispersed Mn-Doped Ru@RuO Core/Shell Nanostructure with High Acidic Water Oxidation Performance Arising from Multiple Synergies.

The high overpotential and unsatisfactory stability of RuO-based catalysts seriously hinder their application in acidic oxygen evolution reaction (OER). Herein, a Ru@RuO core/shell catalyst doped with atomically dispersed Mn species, denoted as Ru@Mn-RuO, is reported, which is prepared by a facile one-pot method. Detailed structural characterizations confirm that Mn is homogeneously and atomically distributed in RuO shell, which causes lattice contraction of RuO.

Impact of diabetes on epicardial reperfusion and mortality in a contemporary STEMI population undergoing mechanical reperfusion: Insights from the ISACS STEMI COVID 19 registry.

Background And Aim: Diabetes has been shown in last decades to be associated with a significantly higher mortality among patients with ST-segment elevation myocardial infarction (STEMI) treated with primary PCI (PPCI). Therefore, the aim of current study was to evaluate the impact of diabetes on times delays, reperfusion and mortality in a contemporary STEMI population undergoing PPCI, including treatment during the COVID pandemic.

Methods And Results: The ISACS-STEMI COVID-19 is a large-scale retrospective multicenter registry involving PPCI centers from Europe, Latin America, South-East Asia and North-Africa, including patients treated from 1st of March until June 30, 2019 and 2020.

Self-Similar Ligand for 2D Zr(IV)-Based Metal-Organic Frameworks: Fluorescent Sensing and Catalysis.

Two-dimensional (2D) metal-organic framework sheets, in comparison to the 3D analogues, offer potential advantages for intercalation of guest components between the layers, exfoliation/dispersion into solutions, and processing into thin films. As a versatile platform for leveraging organic functions, the 2D Zr(IV)-carboxylate net here features a dendritic Sierpinski tritopic linker with conjugated alkyne branches and a photoactive triphenylamine core. The 2D solid can be easily dispersed in water and many other solvents, resulting in stable and fluorescent suspension for sensing nitro aromatic compounds and Fe ions with high quenching efficiencies and ultralow limits of detection.

Phase change material-based tunable Fano resonant optical coatings and their applications.

Thin-film coatings offer a scalable optical platform, as compared to nanopatterned films, for various applications including structural coloring, photovoltaics, and sensing. Recently, Fano resonant optical coatings (FROCs) have gained attention. FROCs consist of coupled thin film nanocavities composed of a broadband and a narrowband optical absorber.

Observation of perovskite topological valley exciton-polaritons at room temperature.

Topological exciton-polaritons are a burgeoning class of topological photonic systems distinguished by their hybrid nature as part-light, part-matter quasiparticles. Their further control over novel valley degree of freedom (DOF) has offered considerable potential for developing active topological optical devices towards information processing. Here, employing a two-dimensional (2D) valley-Hall perovskite lattice, we report the experimental observation of valley-polarized topological exciton-polaritons and their valley-dependent propagations at room temperature.

3D Printed Carbon Nanotube/Phenolic Composites for Thermal Dissipation and Electromagnetic Interference Shielding.

Here we demonstrate direct ink write (DIW) additive manufacturing of carbon nanotube (CNT)/phenolic composites with heat dissipation and excellent electromagnetic interference (EMI) shielding capabilities without curing-induced deformation. Such polymer composites are valuable for protecting electronic devices from overheating and electromagnetic interference. CNTs were used as a multifunctional nanofiller to improve electrical and thermal conductivity, printability, stability during curing, and EMI shielding performance of CNT/phenolic composites.
