Tellurium nanotubes (TeNT) heterojunction with Tellurium oxide (TeO) were prepared by in situ oxidation at elevated temperatures in air. The chemiresistive type NO sensor was then fabricated by depositing the synthesized TeNT/TeO on the integrated gold electrodes. The response of the TeNT/TeO based sensor to 600 ppb NO was 38.

The analysis of human exhaled gas is crucial for early and noninvasive diagnosis. However, the complex composition and high-humidity of exhaled gas pose significant challenges to the application of gas sensors. This research focuses on the development of a chemiresistive ammonia sensor based on the polyaniline/tin disulfide (PANI/SnS) heterojunction, which is fabricated by hydrothermal and in-situ polymerization techniques.

Navigating through soft and highly confined environments is crucial for bacteria moving within living organisms' tissues, yet this topic has been less explored. In our study, we experimentally harnessed the unique biconcave geometry of red blood cells (RBCs) to enable real-time visualization of swimming interacting with soft RBCs. Our findings show that RBCs adhering to a rigid surface can enclose spaces comparable to the size of bacteria, effectively entrapping them.

Present study investigated heavy metal pollution in the continuous upper river-estuary-sea systems of the Yellow River Delta (YRD). Significant seasonal differences (p < 0.05) for the heavy metal overall profile were observed, although there were no significant spatial variations among the different water bodies.

The method combining Monte Carlo (MC) simulation and mesh-type cell models provides a way to accurately assess the cellular dose induced by-emitters. Although this approach allows for a specific evaluation of various nuclides and cell type combinations, the associated time cost for obtaining results is relatively high. In this work, we propose a Microdosimetric assessment method for Internal exposure of-emitters based on Mesh-type Cell cluster models (abbreviated as MIMC-).

Fungi play important roles in ecosystems. Analyzing fungal communities in environments has long been a challenge due to the large difference in compositions retrieved using different methods or sequencing regions, obscuring the true abundance and species information. Our study aimed to compare and determine more accurate approach for evaluating fungal populations in river sediment.

Background: T-cell lymphoblastic lymphoma/leukemia (T-LBL/ALL) is an aggressive form of hematological malignancy associated with poor prognosis in adult patients. Histone deacetylases (HDACs) are aberrantly expressed in T-LBL/ALL and are considered potential therapeutic targets. Here, we investigated the antitumor effect of a novel HDAC inhibitor, chidamide, on T-LBL/ALL.

Article Synopsis
  • Pseudorabies (PR) is an infectious disease caused by the pseudorabies virus (PRV), and this study focused on detecting and analyzing the recent outbreaks of genotype II PRV.
  • Researchers isolated brain tissues suspected of PRV infection, sequenced the virulence-related genes, and conducted pathogenicity evaluations using mice and piglets.
  • The isolated strain, named PRV TJbd2023, showed high pathogenicity, causing severe symptoms and a 66.7% mortality rate in suckling piglets, indicating it may be linked to recent outbreaks and vaccine failures in Tianjin, China.

'Chungui' is a newly promoted tea cultivar in China, renowned for producing oolong tea with a distinctive jasmine-like aroma. However, the genetic basis of this unique aroma remains unclear. In this study, the 'Chungui' genome, one of the most complete and well-annotated tea genomes, was assembled using PacBio HiFi reads and Hi-C sequencing.

Understanding the epigenetic responses to mechanical wounding stress during the postharvest processing of oolong tea provides insight into the reprogramming of the tea genome and its impact on tea quality. Here, we characterized the 5mC DNA methylation and chromatin accessibility landscapes of tea leaves subjected to mechanical wounding stress during the postharvest processing of oolong tea. Analysis of the differentially methylated regions and preferentially accessible promoters revealed many overrepresented TF-binding motifs, highlighting sets of TFs that are likely important for the quality of oolong tea.

A new cocrystalline form of metronidazole (MET) with propyl gallate (PRO), referred to as MET-PRO, has been successfully synthesized and characterized. Structural characterization reveals that MET and PRO are present in a 1:1 ratio within the cocrystal lattice, with one water molecule equivalent incorporated into the structure. This arrangement facilitates the formation of MET-PRO heterodimers and multiple stable units, collectively constructing a three-dimensional supramolecular network.

In this study, starch (S) was gelatinized and carbonized to prepare carbonized/gelatinized S (CGS) as the research material. Then, peat extract (Pe) and surfactants with different ratios were single- and multi-modified on CGS, respectively, to prepare Pe-modified CGS (Pe-CGS) and multi-modified CGS, respectively. The microscopic morphology of multi-modified CGS was studied using various testing methods.

The mechanical stimulation of cells from the surrounding environment is an important life activity. However, there has been a lack of dynamically quantitative analysis of cell morphology under mechanical stimulations. A theoretical model for the evolution of cell morphology under stretching is proposed by analyzing the transformation between cell deformation energy and adhesion energy.

Physicochemical and toxicological characterization of leather tanning wastewater has been widely documented. However, few reports have examined the response of denitrification N and NO emissions in riparian sediments of tannery wastewater-receiving rivers. In this study, N-nitrate labeling was used to reveal the effects of tanning wastewater on denitrification N and NO emission in a wastewater-receiving river (the old Mang River, OMR).

Using the self-developed fused indium wetting technology and planar waveguide, the uniform heat dissipation of the slab crystal and uniform pumping of the pump light were achieved, respectively. Based on the master oscillator power amplification (MOPA) scheme, the power was then amplified when the seed light source passed through the Nd:YAG slab crystal three times. Additionally, the image transfer system that we added to the amplified optical path achieved high beam quality.

Controllable droplet manipulation has diverse applications; however, limited methods exist for externally manipulating droplets in confined spaces. Herein, we propose a portable triboelectric electrostatic tweezer (TET) by integrating electrostatic forces with a superhydrophobic surface that can even manipulate droplets in an enclosed space. Electrostatic induction causes the droplet to be subjected to an electrostatic force in an electrostatic field so that the droplet can be moved freely with the TET on a superhydrophobic platform.

(), belonging to the / gene family, is an important gene regulating the flowering transition and inflorescence architecture during plant development. Given its importance to plant adaptation and crop improvement, has been extensively studied in related plant research; however, the specific role and underlying molecular mechanisms of in the continuous flowering of perennial plants remains elusive. Here, we isolated and characterized homologous genes from two species with different flowering-period phenotypes: was isolated from , a precious species blooming in summer and flowering throughout the year, and was isolated from , which blooms in winter and spring.

A strategy to manipulate droplets on the lubricated slippery surfaces using tribostatic electricity is proposed. By employing femtosecond laser-induced porous microstructures, we prepared a slippery surface with ultralow adhesion to various liquids. Electrostatic induction causes the charges within the droplet to be redistributed; thus, the droplet on the as-prepared slippery surfaces can be guided by electrostatic force under the electrostatic field, with controllable sliding direction and unlimited transport distance.

Article Synopsis
  • Heavy metal exposure, particularly copper ions (Cu), affects gut microbiome function and tolerance, with a focus on children's responses yet to be clearly understood.
  • In experiments with fecal microbes from healthy children, it was found that Lactobacillus sp. and Lactococcus sp. provided protection against Cu toxicity, although their benefits diminished at higher Cu concentrations (≥ 4 mg/L).
  • The study concluded that maintaining a safe Cu concentration of 2 mg/L is crucial for preserving gut microbiota balance, as higher levels lead to increased pathogens and decreased detoxification abilities, posing health risks for children.
