Abstract	Root-knot nematodes (RKNs) inflict extensive damage to global agricultural production. Intercropping has been identified as a viable agricultural tool for combating RKNs, but the mechanisms by which intercropped plants modulate RKN parasitism are still not well understood. Here, we focus on the cucumber-amaranth intercropping system. We used a range of approaches, including the attraction assay, in vitro RNA interference (RNAi), untargeted metabolomics, and hairy root transformation, to unveil the mechanisms by which weak host plants regulate Meloidogyne incognita chemotaxis towards host plants and control infection. Amaranth roots showed a direct repellence to M. incognita through disrupting its chemotaxis. The in vitro RNAi assay demonstrated that the Mi-flp-1 and Mi-flp-18 genes (encoding FMRFamide-like peptides) regulated M. incognita chemotaxis towards cucumber and controlled infection. Moreover, M. incognita infection stimulated cucumber and amaranth to accumulate distinct metabolites in both root tissues and rhizosphere soils. In particular, naringenin and salicin, enriched specifically in amaranth rhizosphere soils, inhibited the expression of Mi-flp-1 and Mi-flp-18. In addition, overexpression of genes involved in the biosynthesis of pantothenic acid and phloretin, both of which were enriched specifically in amaranth root tissues, delayed M. incognita development in cucumber hairy roots. Together, our results reveal that both the distinct host status and disruption of chemotaxis contribute to M. incognita inhibition in intercropping.

Abstract	Soil degradation is a global menace to agricultural crop production. Since loss of soil organic carbon (SOC) is a significant characteristic of soil degradation and since SOC underpins nearly all critical soil functions, a broad range of C-rich amendments (CRAs) have been applied to avoid soil degradation. However, little information is available regarding how various CRAs influence overall soil quality. Here, we conducted experimental trials under field conditions simultaneously at two sites (Beijing and Ningxia; the nutrient-holding capacity was much higher in the Beijing soil than in the Ningxia soil) over two consecutive years, to investigate effects of various CRAs (i.e. straw-C, composted straw-C, and humic acid-C) on overall soil quality and tomato yields. The overall soil quality was expressed by the soil quality index (SQI) covering a wide range of soil physical, chemical and microbial properties. In general, straw-C addition enhanced SQI mainly at Beijing site through increasing soil water content and plant beneficial bacterium Myxococcota, and decreasing soil pH (alleviating alkalization). Composted straw-C addition increased SQI primarily at Ningxia site by enhancing soil porosity, nutrient availability and plant beneficial bacterium Firmicutes, and reducing soil pH, harsh environment-adapted bacteria Methylomirabilota and Gemmatimonadota, and plant fungal pathogen Basidiomycota. However, humic acid-C addition had no effect on SQI at any experimental site. The SQI showed a significant positive correlation with either root biomass or tomato yields at both sites. Together, our results demonstrate that straw-C addition is an effective method for enhancing overall soil quality and crop productivity in soils having a high nutrient-holding capacity (Beijing), while composted straw-C addition is beneficial to soils having a low nutrient-holding capacity (Ningxia).

Abstract	Saliva testing is a vital method for clinical applications, for its noninvasive features, richness in substances, and the huge amount. Due to its direct anatomical connection with oral, digestive, and endocrine systems, clinical usage of saliva testing for these diseases is promising. Furthermore, for other diseases that seeming to have no correlations with saliva, such as neurodegenerative diseases and psychological diseases, researchers also reckon saliva informative. Tremendous papers are being produced in this field. Updated summaries of recent literature give newcomers a shortcut to have a grasp of this topic. Here, we focused on recent research about saliva biomarkers that are derived from humans, not from other organisms. The review mostly addresses the proceedings from 2016 to 2022, to shed light on the promising usage of saliva testing in clinical diagnostics. We recap the recent advances following the category of different types of biomarkers, such as intracellular DNA, RNA, proteins and intercellular exosomes, cell-free DNA, to give a comprehensive impression of saliva biomarker testing.

Abstract	For lithium-oxygen batteries (LOBs), the leakage and volatilization of a liquid electrolyte and its poor electrochemical performance are the main reasons for the slow industrial advancement. Searching for more stable electrolyte substrates and reducing the use of liquid solvents are crucial to the development of LOBs. In this work, a well-designed succinonitrile-based (SN) gel polymer electrolyte (GPE-SLFE) is prepared by in situ thermal cross-linking of an ethoxylate trimethylolpropane triacrylate (ETPTA) monomer.

Abstract	Intercropping systems often contribute to soil health management including inhibiting root-knot nematode disease. The main purpose of this study was to investigate the potential effect of the cucumber-amaranth intercropping system on soil biota, specifically the nematode and microbial communities. Furthermore, the cucumber root-nematode disease was also evaluated. The study found significant effects of cultivation systems (cucumber-amaranth intercropping and cucumber monocropping) and growing seasons (winter-spring (WS) and autumn-winter (AW)) on both soil nematode and microbial community structures in cucumber root-zone soil. Intercropping resulted in a decrease in the relative abundance of Meloidogyne spp., which was consistent with the observed alleviation of root-knot nematode disease. Bacterivorous nematodes were dominant in the intercropping system. The microbial biomass and community-level physiological profiles (CLPP) were generally higher in the intercropping system. Beta diversity analysis showed that the composition of microbial communities varied widely among the treatments and growth seasons. These findings suggest that intercropping with amaranth can regulate soil biota, leading to decreased incidence of root-knot nematodes (RKNs) diseases.

Abstract	Lithium-oxygen batteries have attracted great attention in recent years owing to their extremely high theoretical energy density, however, factors such as low actual capacity and poor rate performance hinder the practical application of lithium-oxygen batteries. In this work, a novel electrolyte additive, tetramethylpyrazine (TMP), is introduced into an electrolyte system to enhance the electrochemical performance of the lithium-oxygen batteries. TMP does not undergo its own redox reaction within the charge-discharge voltage range, which will not affect the electrochemical stability of the electrolyte. The results show that the addition of TMP can increase the reduction current of oxygen, which will promote the ORR process, and with an optimal TMP content (50 mM), the cell shows a high discharge capacity of 5712.3 mA h g

Abstract	The Zhuang are the largest minority group in China and the aboriginal people of the Guangxi Zhuang Autonomous Region. Over thousands of years, the gene pool of the Zhuang has been shaped by the genetic admixture with the Han Chinese. However, little is known about the paternal genetic structure of the modern Zhuang people. Here, we used a high-resolution panel comprising 233 Y-chromosomal single-nucleotide polymorphisms (Y-SNPs) and 37 Y-chromosomal short tandem repeats (Y-STRs) to illuminate the paternal genetic structure and affinities of the Zhuang population. Their Y-SNP haplogroup diversity reached 0.9580 with 44 different subhaplogroups and their Y-STR haplotype diversity reached 1.0. Several bioinformatics analyses were conducted comparing the Zhuang to various reference populations worldwide. Mismatch analysis suggested extensive intermarriages between the Zhuang and O2-dominant groups such as the Han. Genetic clustering analysis of Y-STRs revealed broad genetic affinities between the Zhuang and several geographically, linguistically, and the ethnically related groups such as the southern Han, Bouyei, Li, Miao, and Yao from China. Principal Component Analysis of Y-SNPs demonstrated long-term close genetic relationships among the Zhuang people, Hainan Han, Guangdong Han, and Southeast Asians. Combined Y-STR/Y-SNP analysis showed the Zhuang people and the Hainan Han share common ancestry, illuminating the patrilineal descent of the Zhuang and lending genetic support to commonly accepted ideas regarding the origin of the Hainan Han. Our analysis of Y-SNPs and Y-STRs not only revealed the fine-scale genetic structure of the Zhuang population, but also illuminated their paternal derivation, which is defined by the common ancestry with the Hainan Han, the introgression of southern Chinese groups such as the Han, Bouyei, Li, Miao, and Yao, the long-term phylogenetic relationships with Southeast Asians.

Abstract	This paper reports how a hybrid system composed of transparent dielectric lattices over a metal mirror can produce high-quality lattice resonances for unidirectional lasing. The enhanced electromagnetic fields are concentrated in the cladding of the periodic dielectric structures and away from the metal. Based on a mirror-image model, we reveal that such high-quality lattice resonances are governed by bound states in the continuum resulting from destructive interference. Using hexagonal arrays of titanium dioxide nanoparticles on a silica-coated silver mirror, we observed lattice resonances with quality factors of up to 2750 in the visible regime. With the lattice resonances as optical feedback and dye solution as the gain medium, we demonstrated unidirectional lasing under optical pumping, where the array size was down to 100 μm × 100 μm. Our scheme can be extended to other spectral regimes to simultaneously achieve strongly enhanced surface fields and high quality factors.

Abstract	Background: Root-knot nematodes (RKNs) pose a worldwide threat to agriculture of many crops including cucumber. Genetic transformation (GT) has emerged as a powerful tool for exploration of plant-RKN interactions and genetic improvement of RKN resistance. However, it is usually difficult to achieve a highly efficient and stable GT protocol for most crops due to the complexity of this process. Results: Here we firstly applied the hairy root transformation system in exploring root-RKN interactions in cucumber plants and developed a rapid and efficient tool transformation using Rhizobium rhizogenes strain K599. A solid-medium-based hypocotyl-cutting infection (SHI) method, a rockwool-based hypocotyl-cutting infection (RHI) method, and a peat-based cotyledon-node injection (PCI) method was evaluated for their ability to induce transgenic roots in cucumber plants. The PCI method generally outperformed the SHI and RHI methods for stimulating more transgenic roots and evaluating the phenotype of roots during nematode parasitism. Using the PCI method, we generated the CRISPR/Cas9-mediated malate synthase (MS) gene (involved in biotic stress responses) knockout plant and the LATERAL ORGAN BOUNDARIES-DOMAIN 16 (LBD16, a potential host susceptibility gene for RKN) promoter-driven GUS expressing plant. Knockout of MS in hairy roots resulted in effective resistance against RKNs, while nematode infection induced a strong expression of LBD16-driven GUS in root galls. This is the first report of a direct link between these genes and RKN performance in cucumber. Conclusion: Taken together, the present study demonstrates that the PCI method allows fast, easy and efficient in vivo studies of potential genes related to root-knot nematode parasitism and host response.

Abstract	Background: Schizophrenia (SCZ) has a global prevalence of 1% and increases the risk of mortality, reducing life expectancy. There is growing evidence that the risk of this disorder is higher in males than in females and it tends to develop in early adulthood. The Y chromosome is thought to be involved in biological processes other than sex determination and spermatogenesis. Studies have shown that loss of chromosome Y (LOY) in peripheral blood cells is associated with a variety of diseases (including cancer) and increased all-cause mortality. An analysis of the relationship between LOY and schizophrenia is warranted. Methods: A total of 442 Chinese males (271 patients with schizophrenia vs. 171 controls) were included in this study. The copy numbers of the Y and X chromosomes were detected by positive droplets targeting the amelogenin gene (AMEL) on the Y chromosome and X chromosome (AMELY and AMELX, respectively), using droplet digital PCR (ddPCR). The LOY percentage was defined as the difference between the concentration of AMELX and the concentration of AMELY divided by the concentration of AMELX, denoted as (X - Y)/X. Results: In the Han Chinese population, the LOY percentage was higher in the schizophrenia group than in the control group (p < 0.05), although there was no significant difference in the presence of LOY between the two groups. A strong correlation was found between the average of the disease duration and the average of the LOY percentage (R Conclusions: In the Han Chinese population, the LOY percentage of the disease group was significantly different from that of the control group. The age of onset and duration of schizophrenia might be risk factors for LOY in peripheral blood cells. A larger sample size and expanded clinical information are needed for more in-depth and specific analyses.
