Silica nanoparticles protect rice against biotic and abiotic stresses.

Background: By 2050, the world population will increase to 10 billion which urged global demand for food production to double. Plant disease and land drought will make the situation more dire, and safer and environment-friendly materials are thus considered as a new countermeasure. The rice blast fungus, Magnaporthe oryzae, causes one of the most destructive diseases of cultivated rice worldwide that seriously threatens rice production.

Plant Endophytic Fungus Extract ZNC Improved Potato Immunity, Yield, and Quality.

Endophytic fungi play an important role in plant survival and reproduction, but the role of their metabolites in plant growth and immunity, as well as in crop quality formation, is poorly understood. Zhinengcong (ZNC) is a crude ethanol extract from the endophytic fungus , and previous studies have shown that it can improve the growth and immunity in . The aim of the study was to reveal the trade-off balance between plant growth and immunity by evaluating the mechanisms of ZNC on potato growth, yield, and priming immunity against the oomycete indoors and in the field.

Uptake and depuration kinetics of microplastics with different polymer types and particle sizes in Japanese medaka (Oryzias latipes).

Microplastic (MP) pollution and the related impacts on aquatic species have drawn worldwide attention. However, knowledge of the kinetic profiles of MPs in fish remains fragmentary. In this study, we conducted exposure and depuration tests of the following fluorescent-labeled MPs: polyethylene (PE; sphere with 200 or 20 µm diameter) and polystyrene (PS; sphere with 20 or 2 µm diameter) using juvenile Japanese medaka (Oryzias latipes).

Biglycan promotes the chemotherapy resistance of colon cancer by activating NF-κB signal transduction.

Biglycan (BGN) is overexpressed in cancer stem cells of colon cancer and induces the activation of NF-κB pathway which contributes to the chemotherapy resistance of diverse cancer types. Therefore, we hypothesized that the overexpression of BGN also promoted the development of multiple drug resistance (MDR) in colon cancer via NF-κB pathway. The expression of BGN was bilaterally modulated in colon cancer cell lines HT-29 and SW-480 and the effect of treatments on the cell proliferation and resistance to 5-FU was assessed.

Nanoscale characterization of dynamic cellular viscoelasticity by atomic force microscopy with varying measurement parameters.

Cell mechanics plays an important role in regulating the physiological activities of cells. The advent of atomic force microscopy (AFM) provides a novel powerful instrument for quantifying the mechanics of single cells at the nanoscale. The applications of AFM in single-cell mechanical assays in the past decade have significantly contributed to the field of cell and molecular biology.
