Scope+: An open source generalizable architecture for single-cell RNA-seq atlases at sample and cell levels.

Summary: With the recent advancement in single-cell RNA-sequencing technologies and the increased availability of integrative tools, challenges arise in easy and fast access to large collections of cell atlas. Existing cell atlas portals rarely are open sourced and adaptable, and do not support meta-analysis at cell level. Here, we present an open source, highly optimised and scalable architecture, named Scope+, to allow quick access, meta-analysis and cell-level selection of the atlas data.

Multi-omics analysis reveals the cerebral sex-specific responses to chronic hypoxia in yellow catfish (Pelteobagrus fulvidraco).

Hypoxia disrupts multiple physiological processes, including metabolism, immunity, and reproduction in teleosts. The brain plays a critical role in adapting to environmental changes, regulating the endocrine system, and controlling reproduction. The present study investigated the sex-specific cerebral responses to chronic hypoxia through an integrated analysis of the transcriptome, proteome, and metabolome of yellow catfish.

Naked eye three-dimensional teaching assistant system applied to undergraduate medical imaging education: A pilot study.

The traditional approach of using PowerPoint (PPT) presentations in medical imaging theory classes hinders the spatial thinking ability of most students. Consequently, the learning outcomes are often unsatisfactory. This article proposes a naked eye three-dimensional (3D) medical imaging teaching assistant app based on augmented reality (AR) technology to enhance learning interest, teaching interaction, and effectiveness.

"3 + X D" structured report in radiology standardized resident training: Can it meet high-level teaching objectives?

Purpose: To evaluate the impact of the innovative "3 + X D" structured report (SR) designed based on Bloom's taxonomy on the learning outcomes of radiology residents during standardized training.

Methods: This is a prospective study that recruited 120 radiology residents from our hospital between 2020 and 2022. Randomly selected 60 residents from the 2020 grade to constituted the control group, and randomly selected 60 residents from the 2021 grade to formed the experimental group.

Cold-Source Composite Welding Repair of 9Cr2Mo Thick-Walled Parts: Microstructure, Mechanical Properties, and Finite Element Simulation.

The restoration of large support rollers poses an industrial challenge due to the high energy consumption of traditional repair methods. Consequently, a novel approach for repairing support rollers has been introduced and tested on thick-walled components. Finite element simulations aided the study of welding repairs for large thick-walled components, examining element distribution, microstructure, mechanical properties, and residual stress distribution across various processes.

and models define a molecular signature reference for human embryonic notochordal cells.

Understanding the emergence of human notochordal cells (NC) is essential for the development of regenerative approaches. We present a comprehensive investigation into the specification and generation of NC using a straightforward pluripotent stem cell (PSC)-based system benchmarked with human fetal notochord. By integrating and transcriptomic data at single-cell resolution, we establish an extended molecular signature and overcome the limitations associated with studying human notochordal lineage at early developmental stages.

Vulture: cloud-enabled scalable mining of microbial reads in public scRNA-seq data.

The rapidly growing collection of public single-cell sequencing data has become a valuable resource for molecular, cellular, and microbial discovery. Previous studies mostly overlooked detecting pathogens in human single-cell sequencing data. Moreover, existing bioinformatics tools lack the scalability to deal with big public data.

Effects of Aluminum Addition on Microstructure and Properties of TiC-TiB/Fe Coatings In Situ Synthesized by TIG Cladding.

This study focuses on the synthesis of TiC-TiB/Fe coatings with varying amounts of aluminum (Al) using tungsten inert gas (TIG) cladding and investigates the impact of Al addition on microstructure refinement and performance enhancement of the coatings. The coatings were prepared on a mild steel substrate using TIG cladding. X-ray diffraction (XRD) analysis revealed the presence of TiC, TiB, AlTi, and AlFe phases in the coatings.

A high-quality chromosome-level genome assembly of provides insights into its environmental adaptation and population history.

is a freshwater fish with high economic value, but the lack of genome resources has severely restricted its industrial development and population conservation. Here, we constructed the first chromosome-level genome assembly of with a total length of approximately 662.13 Mb and a contig N50 was 14.

Modeling of Dynamic Recrystallization Evolution for Cr8 Alloy Steel and Its Application in FEM.

In the process of Cr8 roller production, the phenomenon of coarse grain size and uneven grain size often appears, which makes the mechanical properties of the material decrease sharply. Accurate dynamic recrystallization model is the basis for predicting the change of grain size during thermal processing, and is an important basis for refining grain and improving material properties. In this study, the isothermal compression experiment was carried out on Cr8 alloy steel at 900-1200 °C and 0.

Integrated Application of Multiomics Strategies Provides Insights Into the Environmental Hypoxia Response in Pelteobagrus vachelli Muscle.

Increasing pressures on aquatic ecosystems because of pollutants, nutrient enrichment, and global warming have severely depleted oxygen concentrations. This sudden and significant lack of oxygen has resulted in persistent increases in fish mortality rates. Revealing the molecular mechanism of fish hypoxia adaptation will help researchers to find markers for hypoxia induced by environmental stress.

Ultrasonic Cavitation Erosion Behavior of AlCoCrCuFe High Entropy Alloy Coatings Synthesized by Laser Cladding.

Cavitation corrosion resistant coatings are an excellent solution to the cavitation corrosion problem. High entropy alloys provide a new possibility for cavitation resistant coatings due to their excellent comprehensive performance. Laser cladding was employed to synthesize AlCoCrCuFe ( represents the Cr concentration, = 0.

High concordance between Illumina HiSeq2500 and NextSeq500 for reduced representation bisulfite sequencing (RRBS).

Reduced representation bisulfite sequencing (RRBS) provides an efficient method for measuring DNA methylation at single base resolution in regions of high CpG density. This technique has been extensively tested on the HiSeq2500, which uses a 4-colour detection method, however it is unclear if the method will also work on the NextSeq500 platform, which employs a 2-colour detection system. We created an RRBS library and sequenced it on both the HiSeq2500 and NextSeq500, and found no significant difference in the base composition of reads derived from either machine.

MicroRNA-Sequence Profiling Reveals Novel Osmoregulatory MicroRNA Expression Patterns in Catadromous Eel Anguilla marmorata.

MicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs that regulate gene expression by post-transcriptional repression of mRNAs. Recently, several miRNAs have been confirmed to execute directly or indirectly osmoregulatory functions in fish via translational control. In order to clarify whether miRNAs play relevant roles in the osmoregulation of Anguilla marmorata, three sRNA libraries of A.
