Background: Periodontitis is the leading cause of tooth loss in adults due to progressive bone destruction, which is closely related to the dysfunction of bone mesenchymal stem cells (BMSCs). Existing evidence suggests that mitochondrial disorders are associated with periodontitis. However, whether mitochondrial dysregulation contributes to the osteogenic impairment of BMSCs and the underlying mechanisms remain unclear.

Superconductivity in infinite-layer nickelates has stirred much research interest, to which questions regarding the nature of superconductivity remain elusive. A critical leap forward to address these intricate questions is through the growth of high-crystallinity infinite-layer nickelates, including the "parent" phase. Here, we report the synthesis of a high-quality thin-film nickelate, NdNiO.

Article Synopsis
  • Afforestation plays a significant role in ecological restoration by impacting soil microbial communities and carbon cycling, though its overall effects are not fully understood.
  • A meta-analysis of 7045 observations reveals that afforestation boosts microbial biomass and enzyme activities related to carbon and nitrogen but does not significantly affect carbon oxidase activity or nitrogen decomposition rates.
  • The study found a 77% increase in soil organic carbon after afforestation, influenced by factors like initial carbon content, stand age, and aridity, emphasizing the connection between microbial composition and carbon cycling in the context of global climate change.

Atomization is a treatment method to make inhaled liquids into aerosols and transport them to target organs in the form of fog or smoke. It has the advantages of improving the bioavailability of drugs, being painless, and non-invasive, and is now widely used in the treatment of lung and oral lesions. Aerosol inhalation as the route of administration of therapeutic proteins holds significant promise due to its ability to achieve high bioavailability in non-invasive pathways.

Pedunculoside, a triterpene saponin derived from various species, holds potential as a treatment for cardiovascular diseases. However, its clinical application is hindered by poor bioavailability, rapid elimination, and extensive intestinal metabolism to rotundic acid. To address these issues, a water-soluble inclusion complex of pedunculoside, namely, the beta-CD polymer inclusion complex of pedunculoside (pedunculoside-βCDP), was prepared in this study, and a comparative in vitro stability and pharmacokinetic behavior study was performed between pedunculoside and pedunculoside-βCDP.

The metal-hydride-based "topochemical reduction" process has produced several thermodynamically unstable phases across various transition metal oxide series with unusual crystal structures and nontrivial ground states. Here, by such an oxygen (de-)intercalation method we synthesis a samarium nickelate with ordered nickel valences associated with tri-component coordination configurations. This structure, with a formula of SmNiO as revealed by four-dimensional scanning transmission electron microscopy (4D-STEM), emerges from the intricate planes of {303} ordered apical oxygen vacancies.

Objective: The gain of function (GOF) CTNNB1 mutations (CTNNB1 ) in hepatocellular carcinoma (HCC) cause significant immune escape and resistance to anti-PD-1. Here, we aimed to investigate the mechanism of CTNNB1 HCC-mediated immune escape and raise a new therapeutic strategy to enhance anti-PD-1 efficacy in HCC.

Design: RNA sequencing was performed to identify the key downstream genes of CTNNB1 associated with immune escape.

Article Synopsis
  • The paper presents a new method for measuring the load-bearing capacity of roadbeds using a portable falling weight deflectometer (PFWD) to tackle issues with standardization and deflection control.
  • Researchers created a finite element model to analyze how dynamic stress in roadbed soil varies both vertically and horizontally, revealing that stress doesn't simply decrease with depth, but first increases before declining.
  • An improved prediction model combining dynamic bending measurements with static rebound modulus was developed, enhancing the accuracy and efficiency of evaluating highway roadbed bearing capacity.

The search for superconductivity in infinite-layer nickelates was motivated by analogy to the cuprates, and this perspective has framed much of the initial consideration of this material. However, a growing number of studies have highlighted the involvement of rare-earth orbitals; in that context, the consequences of varying the rare-earth element in the superconducting nickelates have been much debated. Here, we show notable differences in the magnitude and anisotropy of the superconducting upper critical field across the La-, Pr-, and Nd-nickelates.

  • The study investigates the differences in positive adaptation between complex posttraumatic stress disorder (CPTSD) and posttraumatic stress disorder (PTSD), focusing on their impacts on well-being.
  • A sample of 1,451 Chinese young adults with childhood adversity was analyzed, revealing that individuals with CPTSD experience lower hedonic and eudaimonic well-being compared to those with PTSD.
  • The findings suggest that CPTSD symptoms, particularly disturbances in self-organization (DSO), negatively affect well-being, while PTSD symptoms may promote posttraumatic growth, emphasizing the need to view CPTSD as a distinct diagnosis and prioritize well-being interventions for those affected.

  • Ticagrelor is being studied as a treatment for stroke and exhibits potential benefits in reducing the risk of both overall and ischemic strokes among patients with vascular risk factors.
  • In a meta-analysis of 15 randomized controlled trials involving over 63,000 patients, ticagrelor showed a lower risk of stroke without significantly increasing all-cause mortality or major bleeding events compared to other treatments.
  • However, ticagrelor was associated with a higher risk of minor bleeding and was found to reduce the risk of recurrent strokes in patients with prior acute ischemic stroke or transient ischemic attack.

Nickel-based superconductors provide a long-awaited experimental platform to explore possible cuprate-like superconductivity. Despite similar crystal structure and d electron filling, however, superconductivity in nickelates has thus far only been stabilized in thin-film geometry, raising questions about the polar interface between substrate and thin film. Here we conduct a detailed experimental and theoretical study of the prototypical interface between NdSrNiO and SrTiO.

Article Synopsis
  • China has implemented "grain-for-green" and grazing exclusion practices since the early 2000s to combat desertification in the desertification-prone region (DPR), but the full effects of these practices on the environment and economy are not well understood.
  • Research shows that between 2001-2020, climate change and CO2 fertilization have played significant roles in improving vegetation cover in the DPR, but farmers and herders have faced income declines greater than the government subsidies provided.
  • To alleviate economic struggles, enhance food security, and improve the effectiveness of its environmental policies, China should adapt its programs to better address the effects of climate change while promoting both ecological and economic stability in the region.
