Phage-ELISA for ultrasensitive detection of .

The M13 phage carries approximately 5 copies of the pIII protein, each of which is capable of displaying a single-chain variable fragment (scFv) that targets a specific antigen. This feature enables the M13 phage to be widely employed in the construction of scFv libraries, thereby facilitating the identification of antibodies with high specificity and affinity for target antigens. In this study, mice were immunized three times with (strain C50041) to induce diverse antibodies.

Isoleucine at position 137 of Hemagglutinin acts as a Mammalian adaptation marker of H9N2 Avian influenza virus.

The H9N2 subtype of avian influenza virus (AIV) is widely distributed among poultry and wild birds and is also a threat to humans. During AIV active surveillance in Liaoning province from 2015 to 2016, we identified ten H9N2 strains exhibiting different lethality to chick embryos. Two representative strains, A/chicken/China/LN07/2016 (CKLN/07) and A/chicken/China/LN17/2016 (CKLN/17), with similar genomic background but different chick embryo lethality, were chosen to evaluate the molecular basis for this difference.

The cross-resistance to etofenprox in Nilaparvata lugens with a high adaptability to resistant rice variety IR56.

Background: The application of resistant rice varieties and insecticides represents two crucial strategies for managing the brown planthopper (BPH), Nilaparvata lugens (Stål). Insects often employ similar detoxification mechanisms to metabolize plant secondary metabolites and insecticides, which poses a potential risk that BPH population adapted to resistant rice may also obtain resistance to some insecticides.

Results: Here in a BPH population (R-IR56) that has adapted to the resistant rice variety IR56 through continuous selection, the moderate resistance to etofenprox was observed.

Synergistic Enhancing of Biological Activity and Natural Light Self-Degradation of Organic-Inorganic Hybrid Nano-organometallic Pesticide-Fused Phenylpyrazole Amine Derivatives with Hollow Box TiO by One-pot Microwave Synthesis.

Nano-TiO as an antimicrobial inorganic material, can stimulate cells to produce reactive oxygen species and exhibit effective biochemical properties; however, phenylpyrazole derivatives, as organic pesticides, are widely used in agriculture and food. To find novel pesticides with environmental friendliness, combined with three-dimensional quantitative structure-activity relationship (3D-QSAR) prediction analysis, three types of alkaloidal phenylpyrazole amine derivatives (PA) were synthesized by a one-pot microwave method. Based on the dye sensitization strategy, four nano-organometallic pesticides (PT) were prepared by organic-inorganic hybridization.

N6-methyladenosine modification of host Hsc70 attenuates nucleopolyhedrovirus infection in the lepidopteran model insect Bombyx mori.

N6-methyladenosine (m6A) is the most prevalent internal modification on mRNA and plays critical roles in various biological processes including virus infection. It has been shown that m6A methylation is able to regulate virus proliferation and host innate immunity in mammals and plants, however, this antiviral defense in insects is largely unknown. Here we investigated function of m6A and its associated methyltransferases in nucleopolyhedrovirus (BmNPV) infection in silkworm.

Mechanistic insights into ferroptosis and apoptosis pathways: Synergistic effects of multi-organ toxicity and transgenerational effects induced by co-exposure of epoxiconazole and aflatoxin B1 in zebrafish.

Introduction: In the environment, mycotoxins and fungicides frequently coexist, potentially causing synergistic risks to organisms. Epoxiconazole (EPO) and aflatoxin B1 (AFB1) are a common fungicide and mycotoxins, respectively, which are widely present in the environment and have toxic effects on multiple organs once entering the organism, but it is still unclear whether the co-exposure has a synergistic toxic effect.

Objectives: This study delves into the molecular mechanisms underlying the co-exposure to EPO and AFB1, emphasizing multi-organ toxicity in female zebrafish (F0 generation) and potential transgenerational impacts on the offspring embryos (F1 generation) through multi-omics approaches.

Soil nitrogen deficiency aggravated the aging of biodegradable microplastics in paddy soil under the input of organic substances with contrasting C/N ratios.

The application of organic substances to the agricultural field has effectively enhanced soil nutrient levels and crop yields. Biodegradable microplastics (bio-MPs), a pervasive emerging contaminant, may potentially impact the soil ecosystem through their aging process. Here, a 150-day dark incubation experiment was conducted to elucidate the disparities in the aging process of polylactic acid bio-MPs (PLA-MPs) in soils with contrasting C/N ratios of organic substances, as the mechanisms underlying this process remain unclear.
