Unusual charge density wave introduced by the Janus structure in monolayer vanadium dichalcogenides.

As a fundamental structural feature, the symmetry of materials determines the exotic quantum properties in transition metal dichalcogenides (TMDs) with charge density waves (CDWs). The Janus structure, an artificially constructed lattice, provides an opportunity to tune the electronic structures and their associated behavior, such as CDW states. However, limited by the difficulties in atomic-level fabrication and material stability, the experimental visualization of the CDW states in two-dimensional (2D) TMDs with Janus structure is still rare.

Myopia control efficacy of peripheral defocus modifying spectacle lenses in children and adolescents: a Meta-analysis.

Aim: To evaluate the effects of microlens design of peripheral defocus modifying spectacle lenses (PDMSLs) and non-microlens design of PDMSLs on controlling myopia progression in children and adolescents.

Methods: A systematic search was carried out in the PubMed, Cochrane Library, Embase, CNKI, and Web of Science databases. The search targeted randomized controlled trials (RCTs) and cohort studies (CTs) that explored the effects of PDMSLs on myopia control among children and adolescents.

Overweight in mediating the association between depression and new-onset diabetes: A population-based research from Health and Retirement Study.

Background: Several studies have suggested a close link between depression, overweight, and new-onset diabetes, particularly among middle-aged and older populations; however, the causal associations remain poorly understood.

Aim: To investigate the role of overweight in mediating the association between depression and new-onset diabetes in middle-aged and older populations.

Methods: Data of 9426 individuals aged ≥ 50 years from the 1998-2016 Health and Retirement Study database were analyzed.

Panax Notoginseng Saponins promotes the meningeal lymphatic system-mediated hematoma absorption in intracerebral hemorrhage.

Background: Hematoma clearance is crucial for treating intracerebral hemorrhage (ICH). Currently, there is a lack of pharmacological therapy aimed at promoting hematoma absorption. Meningeal lymphatic system, as a drain of brain, is a potential therapeutic approach in ICH.

Blockade of adenosine A receptor alleviates cognitive dysfunction after chronic exposure to intermittent hypoxia in mice.

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is widely known for its multiple systems damage, especially neurocognitive deficits in children. Since their discovery, adenosine A receptors (ARs) have been considered as key elements in signaling pathways mediating neurodegenerative diseases such as Huntington's and Alzheimer's, as well as cognitive function regulation. Herein, we investigated AR role in cognitive impairment induced by chronic intermittent hypoxia (CIH).

[Effects of the Veterinary Antibiotic Sulfamethazine on NO Emissions and the Associated Microbiological Mechanism in a Rice Field].

Veterinary antibiotics can enter into croplands with animal excrement and can have effects on nitrification and denitrification processes in the agricultural soils. A field experiment was conducted to evaluate the effect of sulfamethazine (SMZ) on NO emissions, nitrification, denitrification, and related functional gene abundances within a paddy field. Five treatments were used in the experiment, namely, no fertilizer and no antibiotics applied (CK), and pig manure used as basal fertilizer plus urea applied as topdressing with the addition of 0, 5, 15, and 30 mg·kg SMZ (SMZ0, SMZ5, SMZ15, and SMZ30, respectively).

[Distribution Characteristics of Urea and Constitution of Dissolved Nitrogen in the Bohai Sea and the Huanghai Sea in Spring].

Based on the investigation of the Huanghai Sea and the Bohai Sea in Spring( April to May) of 2014, the concentrations of urea and inorganic nitrogen were determined respectively by diacetyl monoxime-Semicarbazide Hydrochloride method and Spectrophotometric method. The distribution of urea and the component of dissolved nitrogen were analyzed. The influencing factors of urea were also discussed.

Achieving Energy Conservation in Poisson-Boltzmann Molecular Dynamics: Accuracy and Precision with Finite-Difference Algorithms.

Violation of energy conservation in Poisson-Boltzmann molecular dynamics, due to the limited accuracy and precision of numerical methods, is a major bottleneck preventing its wide adoption in biomolecular simulations. We explored the ideas of enforcing interface conditions by the immerse interface method and of removing charge singularity to improve the finite-difference methods. Our analysis of these ideas on an analytical test system shows significant improvement in both energies and forces.
