Background: Learning interest is an intrinsic motivation that dynamically interacts with friendships. Students alter their learning interests to assimilate with their friends and actively establish friendships on the basis of similar interests. These processes do not operate in isolation but rather in the broader peer context.

Landslide disasters have characteristics of frequent occurrence, widespread impact, and high destructiveness, posing serious threats to human lives, property, and the ecological environment. Timely and accurate early identification of landslides remains an urgent issue within the disaster prevention field. This study focuses on Jianzha County, Qinghai Province, integrating PS-InSAR, SBAS-InSAR, and optical remote-sensing techniques to delineate potential landslide-prone areas.

Chromatin accessibility is a critical determinant of gene transcriptional expression and regulated by histones modification. However, the potential for manipulating chromatin accessibility to regulate radiation sensitivity remains unclear. Our findings demonstrated that the histone demethylase inhibitor, 5-carboxy-8-hydroxyquinoline (IOX1), could enhance the radiosensitivity of non-small cell lung cancer (NSCLC) in vitro and in vivo.

Background: Learning is a self-regulated loop where learning strategies and achievements are interrelated. In reading, although some studies have explored the relationship between different learning strategies (memorization, elaboration and control) and reading achievement, little is known about how they interact over time. Even though the longitudinal relationship was revealed in some studies, most of the evidence was based on the whole population, regardless of gender differences.

Mechanoluminescence (ML) materials have found potential applications in information storage, anti-counterfeiting, and stress sensing. Conventional stress sensing based on absolute ML intensity is prone to significant mistakes owing to the unpredictability of measurement surroundings. However, implementing a ratiometric ML sensing technique may considerably ameliorate this issue.

Background: To explore extraperitoneal approach as an optimal option for reducing peritoneal disruption at a single-level disc in anterior lumbar interbody fusion (ALIF).

Methods: First, abdominal axial CT images obtained from 111 patients were observed to evaluate the distribution of extraperitoneal fat at L2-S1 and measure the lateral distances between the midline and the lateral borders of the rectus and the extraperitoneal fat for each disc level. Second, eight embalmed corpses were dissected along the lateral border of the rectus to expose the peritoneum, which was then separated laterally and medially to evaluate the distribution of fat and peritoneum adhesion.

Objective: Hidden blood loss (HBL), as a perioperative complication of percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP), affects the quality of life of older adults with poor health status, but it is often ignored by clinical surgeons. The purpose of this study was to discuss the risk factors for perioperative HBL through meta-analysis.

Methods: We systematically searched PubMed, Embase, Cochrane Library, Web of Science, Scopus, Google Scholar, Chinese National Knowledge Infrastructure, and Wan Fang from establishment of the database to September 2022.

Dansyl chloride fluorophore exhibits typical aggregation induced fluorescence emission behavior in acetone/water solution. To realize the integration of detective and adsorptive functions, dansyl chloride is covalently immobilized on cellulose substrate to fabricate an efficient adsorbent for mercury ions in water. The as-prepared material exhibits excellent fluorescence sensing performance exclusively for Hg (II) with the presence of other metal ions.

A pot experiment was conducted to evaluate how nitrogen (N) availability influences cadmium (Cd) absorption, translocation and stress tolerance in roots of Populus euramericana. Seedling growth was sensitive to N deficiency, but it was unaltered by Cd exposure. Cadmium absorption by roots was promoted by N deficiency, resulting in a higher root Cd concentration compared to the N-sufficient condition.
