Urbanization causes alteration in atmospheric, soil, and hydrological factors and substantially affects a range of morphological and physiological plant traits. Correspondingly, plants might adopt different strategies to adapt to urbanization promotion or pressure. Understanding of plant traits responding to urbanization will reveal the capacity of plant adaptation and optimize the choice of plant species in urbanization green.

Using biomimetic self-assembly and microstamping techniques, we construct a hierarchical bilayer architecture consisting of intrafibrillarly mineralized collagen resembling bone and cementum, and unmineralized parallel-aligned fibrils mimicking periodontal ligament. The prepared biphasic scaffold possesses unique micro/nano structure, differential mechanical properties, and growth factor-rich microenvironment between the two phases, realizing a perfect simulation of natural periodontal hard/soft tissue interface.

Methods: Data were analyzed using descriptive statistics, hypothesis tests, and logistic regression.
Myocardial infarction (MI) is one of the leading threats to human health. N6-methyladenosine (m6A) modification, as a pivotal regulator of messenger RNA stability, protein expression, and cellular processes, exhibits important roles in the development of cardiac remodeling and cardiomyocyte contractile function. The expression levels of m6A regulators were analyzed using the GSE5406 database.

Objective: To systematically evaluate the effect of NIBS on dysphagia after stroke and compare the effects of two different NIBS.
Statins are used in clinical practice to prevent from complications such as cerebral vasospasm (CVS) after aneurysmal subarachnoid hemorrhage (aSAH). However, the efficacy and safety of statins are still controversial due to insufficient evidence from randomized controlled trials and inconsistent results of the existing studies. This meta-analysis aimed to systematically review the latest evidence on the time window and complications of statins in aSAH.

The objective was to determine these associations by conducting a meta-analysis of available studies.
Methods: Three electronic databases were searched for studies that quantified dietary omega-3 PUFA and/or fish intake from inception to December 2020 without language restriction.

Methods: 34 amnestic MCI subjects entered this study, conducting neuropsychological tests, MRI and Technetium ethyl cystine dimer brain perfusion SPECT imaging. All subjects were divided into those with CSVD and those without CSVD.
Fe(III)-oxyhydroxide composites are efficient adsorption materials, however, their detailed geometrical structures and adsorption mechanisms in a broad pH range are still unclear. In this study, the structures of arsenic(V) adsorbed on Fe(III)-oxyhydroxide adsorption complexes were investigated using hybrid density functional theory calculations together with experimental Fourier transform infrared (FT-IR) spectroscopy. Adsorption experiments showed higher arsenic(V) removal rates in the range of pH 5.

The effect of complement component 5a (C5a) on the differentiation of dental pulp mesenchymal stem cells (DPSCs) is related to dentin reparation. The aim of the present study was to stimulate DPSCs with different concentrations of C5a and evaluate the differentiation of odontoblasts using dentin sialoprotein (DSP).

N-Methyladenosine (mA) RNA modification brings a new dawn for RNA modification researches in recent years. This posttranscriptional RNA modification is dynamic and reversible, and is regulated by methylases ("writers"), demethylases ("erasers"), and proteins that preferentially recognize mA modifications ("readers"). The change of RNA mA modification regulates RNA metabolism in eucaryon, including translation, splicing, exporting, decay, and processing.

The sensitive detection of telomerase plays a pivotal role in the early diagnosis and therapeutic treatment of osteosarcoma. We report here an strategy for sensitive telomerase activity detection through the integration of rolling circle amplification (RCA) and a clustered regularly spaced short palindrome repeats (CRISPR)-Cas12a system.

One of the reasons for this is that the charge transport in conjugated materials is strongly affected by their structure. Further, the charge mobility increases significantly when the conjugated materials exhibit self-assembly, resulting in the formation of ordered structures.
