ConspectusMetal-organic layers (MOLs), as a subclass of two-dimensional (2D) metal-organic frameworks (MOFs), have gained prominence in materials science by combining the structural versatility of MOFs with the unique physical and chemical properties of 2D materials. MOLs consist of metal oxide clusters connected by organic ligands, forming periodically extended 2D architectures with tunable properties and large surface areas. These characteristics endow MOLs with significant potential for applications in catalysis, sensing, energy storage, and biomedicine.

Precisely capturing and manipulating microscale objects, such as individual cells and microorganisms, is fundamental to advancements in biomedical research and microrobotics. Photoactuators based on optical fibers serving as flexible, unobstructed waveguides are well-suited for these operations, particularly in confined locations where free-space illumination is impractical. However, integrating optical fibers with microscale actuators poses significant challenges due to size mismatch, resulting in slow responses inadequate for handling motile micro-objects.

Multiferroics are appealing because of application potentials in data storage devices, sensors, transducers, and energy harvesters. Molecular multiferroics emerge as a promising alternative to inorganic multiferroics due to flexibility, light weight, low toxicity, solution processing, structural diversity, and chemical tunability. While researches have predominantly focused on perovskite structures, studies on molecular ionic multiferroics remain relatively limited.

Inflammatory diseases of the intestinal tract in piglets severely impair the economic performance of pig farms. Pig milk exosomes can encapsulate miRNAs which can then enter the piglet intestine to play an immunomodulatory role. Previously, we comparatively analyzed and identified exosomal miRNAs in the colostrum and mature milk of Bamei and Landrace pigs, and we screened for ssc-miR-22-3p, which is associated with inflammation and immune response; however, the role played by ssc-miR-22-3p in the immune response in IPEC-J2 cells is not yet clear.

4-Hydroxypiridine (4-HPy) is a green chemistry corrosion inhibitor for low-carbon steel, valued for its environmental compatibility and low toxicity. Despite lower initial effectiveness than 4-mercapto/4-aminopyridine, 4-HPy's performance is markedly enhanced by halogen ions. By employing second harmonic generation (SHG) spectroscopy combined with electrochemical methods, Raman spectroscopy, atomic force microscopy, x-ray photoelectron spectroscopy, and in situ UV spectroscopy, this study elucidates the synergistic enhancement mechanism of 4-HPy with Cl-, Br-, and I- in 0.

  • Personality significantly influences health-related quality of life (HRQoL) in older adults, particularly highlighting the roles of neuroticism and extraversion.
  • Both personality traits affect sleep quality, which in turn impacts HRQoL—neuroticism tends to worsen HRQoL while extraversion tends to improve it.
  • The place of residence (urban vs. rural) moderates these relationships, indicating that living environment plays a crucial role in how personality affects health outcomes.

  • Chemotherapy combined with immunotherapy is the main treatment for advanced esophageal squamous cell carcinoma (ESCC), but response durations and progression-free survival rates are still low, prompting a study on early radiotherapy.
  • Researchers analyzed data from 72 patients who had positive responses to first-line treatments and received radiotherapy, noting improved median progression-free survival (PFS) and overall survival (OS) after treatment, particularly with higher radiation doses.
  • Findings suggest that adding early radiotherapy can enhance outcomes for these patients, but more research is needed to confirm and better understand these benefits.

Ammonia (NH) synthesis via the nitrate reduction reaction (NORR) offers a competitive strategy for nitrogen cycling and carbon neutrality; however, this is hindered by the poor NORR performance under high current density. Herein, it is shown that boron-doped TiCT MXene nanosheets can highly efficiently catalyze the conversion of NORR-to-NH at ambient conditions, showing a maximal NH Faradic efficiency of 91% with a peak yield rate of 26.2 mgh mg , and robust durability over ten consecutive cycles, all of them are comparable to the best-reported results and exceed those of pristine TiCT MXene.

Gastric cancer is one of the most prevalent cancers worldwide, and human epidermal growth factor receptor 2 (HER2)-positive cases account for approximately 20% of the total cases. Currently, trastuzumab + chemotherapy is the recommended first-line treatment for patients with HER2-positive advanced gastric cancer, and the combination has exhibited definite efficacy in HER2-targeted therapy. However, the emergence of drug resistance during treatment considerably reduces its effectiveness; thus, it is imperative to investigate the potential mechanisms underlying resistance.

Human epidermal growth factor receptor 2 (HER2) gastric cancer (GC) is a distinct subtype of GC, accounting for 10‑20% of all cases of GC. Although the development of the anti‑HER2 monoclonal antibody trastuzumab has markedly improved response rates and prognosis of patients with HER2 advanced GC (AGC), drug resistance remains a considerable challenge. Therefore, dynamic monitoring of HER2 expression levels can facilitate the identification of patients who may benefit from targeted therapy.

On the path of persisting Moore's Law, one of the biggest obstacles is the "Boltzmann tyranny," which defines the lower limit of power consumption of individual transistors. Negative capacitance (NC) in ferroelectrics could provide a solution and has garnered significant attention in the fields of nanoelectronics, materials science, and solid-state physics. Molecular ferroelectrics, as an integral part of ferroelectrics, have developed rapidly in terms of both performance and functionality, with their inherent advantages such as easy fabrication, mechanical flexibility, low processing temperature, and structural tunability.

Article Synopsis
  • - Glycolytic metabolites, like 3-phosphoglycerate (3-PGA), are not just for energy but can regulate cell fate by influencing p53 activity related to apoptosis.
  • - Low 3-PGA levels shift phosphoglycerate dehydrogenase (PHGDH) function from serine synthesis to activating p53, promoting apoptosis through interactions with proteins like AXIN and HIPK2.
  • - PHGDH mutations can either hinder or enhance p53 activation and apoptosis in liver cancer cells, with caloric restriction providing a potential method to control cancer growth by lowering glucose levels and affecting PHGDH activity.
