Plastic products can degrade into micro/nano plastics (MNPs), which have the potential to adsorb Tris (1,3-dichloro-2-propyl) phosphate (TDCPP) from the environment, thereby creating biological co-exposure risks. Current researches indicate that TDCPP has endocrine-disrupting effects. However, the potential toxicities associated with the co-exposure to TDCPP and MNPs remain largely unclear.

is widely used in industrial chemical synthesis but faces significant challenges due to bacteriophage contamination, which reduces product quality and yield. Therefore, developing an efficient antiphage system is essential. In this study, we develop a CRISPR-Cas9-based antiphage system (CAPS) targeting essential genes of the T7 phage (gene and gene ) with single gRNAs transformed into MG1655 strains expressing Cas9.

Introduction: Brucellosis, an infectious zoonotic disease caused by members of the genus , results in chronic multi-organ injury. Improving the specificity and sensitivity of serological methods for diagnosing brucellosis necessitates the development of novel diagnostic antigens. The twin-arginine translocation (Tat) pathway is responsible for transporting folded proteins across the cytoplasmic membrane and has been implicated in the virulence of .

Brucellosis, caused by Gram-negative Brucella, spreads in human and animal populations through contact with infected animals and products. Developing a rapid and sensitive detection technology for pathogen is crucial to reduce the risk of this disease transmitting between animal populations and to humans. We produced a monoclonal antibody LPS-6B5, which shows high affinity to LPS and limited cross-reactivity with other bacteria.

Article Synopsis
  • Cognitive dysfunction in older adults is influenced by depression and adverse childhood experiences (ACEs) related to deprivation, which can impose significant economic burdens.
  • Research aimed to explore how depression mediates the relationship between these deprivation-related ACEs and cognitive function using data from a large national survey.
  • The findings revealed that both deprivation-related ACEs and depression are negatively correlated with cognitive function, and depression plays a significant mediating role, suggesting that addressing childhood deprivation could help reduce cognitive dysfunction through improved mental health.

Terahertz (THZ) spectroscopy has emerged as a superior label-free sensing technology in the detection, identification, and quantification of biomolecules in various biological samples. However, the limitations in identification and discrimination sensitivity of current methods impede the wider adoption of this technology. In this article, a meticulously designed metasurface is proposed for molecular fingerprint enhancement, consisting of a periodic array of lithium tantalate triangular prism tetramers arranged in a square quartz lattice.

Background: Growing studies have indicated an association between dietary factors and gastroesophageal reflux disease (GERD). However, whether these associations refer to a causal relationship and the potential mechanism by which dietary factors affect GERD is still unclear.

Methods: A two-step mendelian randomization analysis was performed to obtain causal estimates of dietary factors, blood lipids on GERD.

N-Nitrosamine disinfection by-products (NAs-DBPs) have been well proven for its role in esophageal carcinogenesis. However, the role of intratumoral microorganisms in esophageal squamous cell carcinoma (ESCC) has not yet been well explored in the context of exposure to NAs-DBPs. Here, the multi-omics integration reveals () as "facilitators" is highly enriched in cancer tissues and promotes the epithelial mesenchymal transition (EMT)-like subtype formation of ESCC.

Terahertz (THz) spectroscopy has demonstrated significant potential for substance detection due to its low destructiveness and due to the abundance of molecular fingerprint absorption signatures that it contains. However, there is limited research on the fingerprint detection of substances at different temperatures. Here, we propose a THz metamaterial slit array sensor that exploits localized surface plasmons to enhance the electric field within the slit.

BP26 proves to be a highly immunogenic antigen with excellent specificity in brucellosis detection. In China, the authorized use of the Bp26-deleted vaccine M5ΔBP26 for preventing small ruminant brucellosis highlights the importance of developing accurate detection methods targeting BP26, particularly for the diagnosis of differentiation between infected and vaccinated animals (DIVA). Using the traditional mouse hybridoma technique, we successfully obtained 12 monoclonal antibodies (mAbs) targeting BP26.

Article Synopsis
  • Tuberculosis caused by Mycobacterium tuberculosis complex (MTBC) remains a major global health issue, emphasizing the need for effective detection methods to differentiate its main pathogens.
  • The study introduces a new testing method called triplex droplet digital polymerase chain reaction (ddPCR), which uses different probe fluorophores to accurately target genes associated with three pathogens: MTBC, its variants, and BCG.
  • The results show that triplex ddPCR is more sensitive and specific than current methods, detecting lower levels of pathogens in various sample types (including milk, tissue, and swabs) with high repeatability and without cross-reaction to other organisms.

Spectroscopy is a powerful tool to identify the specific fingerprints of analytes in a label-free way. However, conventional sensing methods face unavoidable barriers in analyzing trace-amount target molecules due to the difficulties of enhancing the broadband molecular absorption. Here, we propose a sensing scheme to achieve strong fingerprint absorption based on the angular-scanning strategy on an all-silicon metasurface.
