The real-time monitoring and fault diagnosis of modern machinery and equipment impose higher demands on equipment maintenance, with the extraction of morphological characteristics of wear debris in lubricating oil emerging as a critical approach for real-time monitoring of wear, holding significant importance in the field. The online visual ferrograph (OLVF) technique serves as a representative method in this study. Various semantic segmentation approaches, such as DeepLabV3+, PSPNet, Segformer, Unet, and other models, are employed to process the oil wear particle image for conducting comparative experiments.

MicroRNAs (MiRNAs) play pivotal roles in regulating gene expression, and serve as crucial biomarkers for diagnosis of a variety of disease. However, label-free and sensitive miRNA detection remains a huge challenge due to the low abundance. Herein, we developed an approach through integrating primer exchange reaction (PER) with DNA-templated silver nanoclusters (AgNCs) for label-free and sensitive miRNA detection.

Nickel and cobalt are essential elements that become toxic at high concentrations. Little is known about nickel and cobalt toxicity in aquatic animals. This study aimed to investigate acute and chronic toxicity of nickel and cobalt in Japanese flounder (Paralichthys olivaceous), with emphasis on oxidative stress reactions, histopathological changes, and differences in gene expression.

Three typical surface pretreatment strategies (grind, drawing, polishing) are employed to explore the influence of alloy substrate treatment on microstructure and surface performances of arc-ion plated TiN and ZrN films. The luminance and color of the films are measured by the color coordinate value of CIELab system (a color system which is defined by the International Commission on illumination). The crystal phases, morphology and microstructure are characterized and analyzed by scanning electron microscope (SEM) and X-ray powder diffraction (XRD).

Article Synopsis
  • Sterility in double haploids (DHs) of teleost fish, like the Japanese flounder, limits their use in cloning and breeding but serves as a useful model for studying gonad development and reproductive genes.
  • Researchers sequenced the transcriptome of sterile female DH Japanese flounder, identifying 52,474 gene fragments, with many showing similarity to known sequences, and found 1225 differentially expressed genes linked to sterility.
  • Gene analyses revealed that upregulated genes were tied to steroid metabolism and key signaling pathways, while downregulated genes were connected to immune responses and protein processing, enhancing understanding of reproductive dysfunction in these fish.

The purpose of this research is to investigate the effects of sodium houttuyfonate on the phosphorylation of CaMK II, CREB and ERK 1/2, and the expression of c-Fos. Macrophages were cultured in vitro with or without sodium houttuyfonate in the culture medium. After cell culture, macrophages were lysed and the lysate of the macrophages was collected for analysis.

Unlabelled: To reveal the effects of soybean milk with chromium fortification on the blood glucose and lipid of diabetic rat dealt with alloxan. The alloxan diabetic rats were divided into three groups and were fed continuously with the soybean milk without chromium fortification [Cr 0.25 microgram/(d.
