    Abstract Phenolic compounds, abundant secondary metabolites in plants, profoundly influence soil ecosystems, plant growth, and interactions with herbivores. In this study, we explore the intricate relationships between phenolics, soil microbes, and gall formation in Ageratina adenophora (A. adenophora), an invasive plant species in China known for its allelopathic traits. Using metabolomic and microbial profiling, significant differences in soil microbial composition and metabolite profiles were observed between bulk and rhizosphere soil samples. Phenolics influenced bacterial communities, with distinct microbial populations enriched in each soil type. Additionally, phenolics impacted soil metabolic processes, with variations observed in Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis between different soil treatments. Analysis of phenolic content in plant and soil samples revealed considerable variations, with higher concentrations observed in certain plant tissues and soil types. Bioactive phenols extracted from plant and soil samples were identified using gas chromatography/mass spectrometry (GC-MS), providing insights into the diverse chemical composition of these compounds. Furthermore, the effects of phenolics on plant growth and gall formation were investigated. Phenols exhibited both stimulatory and inhibitory effects on plant growth, with optimal concentrations promoting emergence but higher concentrations hindering growth. Gall formation was influenced by phenolic concentrations, leading to structural alterations in stem tissue and gall morphology. Histochemical analysis revealed starch and lipid accumulation in gall tissues, indicating metabolic changes induced by phenolics. The presence of phenolics disrupted tissue structures and influenced vascular bundle orientation in gall tissues. Overall, our study highlights the multifaceted roles of phenolic compounds in soil ecosystems, plant development, and gall formation, facilitating the utilization of secondary metabolites in agriculture.

    Abstract Objective: To explore the molecular mechanism of long non-coding RNA (lncRNA) LINC00472 in Alzheimer's Disease (AD).
    Method: Ferroptosis-related lncRNAs were screened by GEO database. AD mouse model was constructed for in vivo experimental. The content of Aβ protein and Tau protein hyperphosphorylation were examined in Hippocampal tissue samples of mice. Subsequently, HT22 cells were induced with Aβ25-35 to establish a neuronal injury model of AD in vitro. The expression of FOXO1, a key gene for ferroptosis, was verified by overexpressing/knocking down the LINC00472. The effects of LINC00472 on ROS and lipid peroxidation content, GPX4, and Tau protein in AD model cells were examined by ROS assay, MDA assay, Western Blot and qRT-PCR. Subsequently, the expression of iron ion, FTH, TfRC, and Fpn protein were detected in AD cells.
    Results: The level of FOXO1 was positively correlated with the degree of AD. In vivo experiments showed that the expression of Aβ and Tau hyperphosphorylated were significantly reduced in the inhibitor group and iron was significantly reduced relative to the AD group. In the AD cell model, the content of lipid peroxide was up-regulated, GPX4 protein and mRNA were decreased, and phosphorylation of Tau protein was enhanced in the AD cell model relative to the control group. Whereas knocking down LINC00472 inhibited the up-regulation of lipid peroxide, decreased the level of GPX4, and enhancement of Tau protein phosphorylation, and it reduced iron accumulation, in AD cells.
    Conclusions: LINC00472 affects ferroptosis in AD by regulating iron accumulation, in neuronal cells.

    Abstract Based on the deep learning method, a network model that can quickly and accurately identify the species of Fritillaria cirrhosa species was constructed. The learning method based on deep residual convolutional neural network was used to input the unprocessed original image directly as input, and the features of the image were extracted through convolution and pooling operations. On this basis, the ResNet34 model was improved, and the additional fully connected layer was added in front of the Softmax classifier to improve the learning ability of the network model. Total of 3915 images of three kinds of Fritillaria cirrhosa were used as data sources for the experiments, among which 160 images of each type were randomly selected to form the validation set. The final training set recognition accuracy rate was 95.8%, the validation set accuracy rate reached 92.3%, and the test set accuracy rate was 88.7%. The image recognition method of Fritillaria cirrhosa based on deep learning proposed in this paper is effective and feasible, which can quickly and accurately identify the species of Fritillaria cirrhosa species, and provides a new idea for the intelligent recognition of Chinese medicinal materials.

    Abstract Objective To analyze and compare the clinical features and outcomes of in vitro fertilization-embryo transfer (IVF-ET) cycles in normal responders using gonadotrophin (Gn) releasing hormone (GnRH) antagonist or GnRH agonist long protocol. Methods The clinical data of patients who received IVF treatment and had normal ovarian response to GnRH antagonist or GnRH agonist long protocol in our reproductive center from January 2017 to March 2019 were collected. According to the treatment protocol and the fresh embryo transplanted or not, these patients were divided into Group A (receiving GnRH antagonist, but no fresh embryo transplanted, n=128), Group B (GnRH antagonist, with fresh embryo transplanted, n=138), and Group C (GnRH agonist long protocol, with fresh embryo transplanted, n=720). Besides, the frozen embryo transfer (FET) cycles of Group A were analyzed, and served as Group D. The thickness of endometrium on luteal conversion day and outcome of Group D were compared with those of Group B and Group C. Results ① The duration and dosage of Gn were shorter and less in Group A and B than Group C, and statistical difference was seen in Gn duration (P < 0.05), and in Gn dosage only between Group A and C (P < 0.05). ②On HCG day, the serum estradiol (E2) level were lower in Group A and B than Group C (P < 0.05), the endometrium of Group C was the thickest, and the thickness of endometrium on luteal conversion day of Group D was lower than that on the HCG day of Group A, B and C, where the differences between Group A and B, and Group C and D were statistically significant (P < 0.05). ③ The number of oocytes obtained in Group A and B were less than that in Group C (P < 0.05), but there were no statistical difference in metaphase Ⅱ (MⅡ) oocyte rate, normal fertilization rate and high-quality embryo rate among Group A, B and C. ④ Biochemical pregnancy rate and clinical pregnancy rate had no statistical differences among Group B, C, and D (P < 0.05). Group B had the lowest implantation rate but the ...

    Abstract Human papillomavirus (HPV) infection is one of the worldwide sexually transmitted diseases (STD), and the DNA of HPV can exist in the normal epithelium of reproductive organs of both men and women. Because the majority of HPV infections are asymptomatic, healthy HPV-carriers become the main source of the infection. Studies show that HPV infection in men is correlated with STD, infertility, tumor of reproductive organs, and infection in the sexual partners. Therefore, measures should be taken to reduce male HPV infection, including circumcision, fewer sexual partners, and condom use.

    Abstract Background: The ladybeetle, Coccinella septempunctata, an important predator, is widely used to control aphids, whiteflies, mites, thrips, and lepidopteran pests. Diapause control technology is key to extending C. septempunctata shelf-life and commercialization. Lipid accumulation is a major feature of reproductive diapause, but the function of AKH signaling as a regulator of lipid mobilization in reproductive diapause remains unclear. This study aimed to identify and characterize AKH and AKHR genes, and clarify their functions in reproductive diapause.
    Results: The relative expression levels of CsAKH and CsAKHR were the highest in the head and fat body, respectively, and were significantly decreased under diapause conditions, both in developmental stages and tissues (head, midgut, fat body, and ovary). Furthermore, CsAKH and CsAKHR expression was increased significantly after juvenile hormone (JH) injection, but CsMet silencing significantly inhibited CsAKH and CsAKHR expression, whereas CsMet knockdown blocked the induction effect of JH. CsAKH and CsAKHR knockdown significantly reduced water content, increased lipid storage, and promoted the expression of genes related to lipid synthesis, but significantly blocked ovarian development, and induced forkhead box O (FOXO) gene expression in C. septempunctata under reproduction conditions. By contrast, injection of AKH peptide significantly inhibited FOXO expression, reduced lipid storage, and increased water content in C. septempunctata under diapause conditions.
    Conclusion: These results indicate that CsAKH and CsAKHR are involved in the regulation of lipid accumulation and ovarian development during diapause in C. septempunctata, and provide a promising target for manipulating C. septempunctata diapause. © 2024 Society of Chemical Industry.

    Abstract In this paper, we present a comprehensive point cloud semantic segmentation network that aggregates both local and global multi-scale information. First, we propose an Angle Correlation Point Convolution (ACPConv) module to effectively learn the local shapes of points. Second, based upon ACPConv, we introduce a local multi-scale split (MSS) block that hierarchically connects features within one single block and gradually enlarges the receptive field which is beneficial for exploiting the local context. Third, inspired by HRNet which has excellent performance on 2D image vision tasks, we build an HRNet customized for point cloud to learn global multi-scale context. Lastly, we introduce a point-wise attention fusion approach that fuses multi-resolution predictions and further improves point cloud semantic segmentation performance. Our experimental results and ablations on several benchmark datasets show that our proposed method is effective and able to achieve state-of-the-art performances compared to existing methods.

    Abstract Carbon-based materials have been successfully applied in the zinc ion batteries to improve the energy storage capability and durability of zinc anodes. In this review, four types of carbon materials (conventional carbons, fiber-like carbons, carbon nanotubes, graphene and other 2D carbon materials) are introduced based on the electrode preparation, physicochemical property and battery performance. Several modification strategies are also illustrated, such as heteroatom doping, hierarchical design and metal/carbon composites. Besides the discussion of existing issues of zinc anodes, the structure-performance relationships are analyzed in depth. Finally, conclusive remarks of this review are summarized and prospects of the future improvement are proposed.

    Abstract Seed dormancy is an important agronomic trait in crops, and plants with low dormancy are prone to preharvest sprouting (PHS) under high‐temperature and humid conditions. In this study, we report that the GATA transcription factor TaGATA1 is a positive regulator of seed dormancy by regulating TaABI5 expression in wheat. Our results demonstrate that TaGATA1 overexpression significantly enhances seed dormancy and increases resistance to PHS in wheat. Gene expression patterns, abscisic acid (ABA) response assay, and transcriptome analysis all indicate that TaGATA1 functions through the ABA signaling pathway. The transcript abundance of TaABI5, an essential regulator in the ABA signaling pathway, is significantly elevated in plants overexpressing TaGATA1. Chromatin immunoprecipitation assay (ChIP) and transient expression analysis showed that TaGATA1 binds to the GATA motifs at the promoter of TaABI5 and induces its expression. We also demonstrate that TaGATA1 physically interacts with the putative demethylase TaELF6‐A1, the wheat orthologue of Arabidopsis ELF6. ChIP–qPCR analysis showed that H3K27me3 levels significantly decline at the TaABI5 promoter in the TaGATA1‐overexpression wheat line and that transient expression of TaELF6‐A1 reduces methylation levels at the TaABI5 promoter, increasing TaABI5 expression. These findings reveal a new transcription module, including TaGATA1–TaELF6‐A1–TaABI5, which contributes to seed dormancy through the ABA signaling pathway and epigenetic reprogramming at the target site. TaGATA1 could be a candidate gene for improving PHS resistance.
