N-doped carbon nanotubes encapsulated NiZnC nanoparticles catalyst for peroxymonosulfate activation: Heterojunction structure and N-doping enhance electron transfer capability.

In this paper, a type of N-doped carbon nanotube-coated NiZnC metal nanoparticle heterostructure catalyst (NZC-C-700) was prepared by two-step roasting method and applied to depredate bisphenol A (BPA) with peroxymonosulfate (PMS) activation. Characterizations and first principles calculation (DFT) reveal that the heterostructure formed by the graphite carbon layer and NiZnC metal nanoparticles, coupled with various N doping, can effectively modulate surface charge distribution, which could improve charge transfer capability between the catalyst and PMS. Meanwhile, the results of quenching experiments, electron paramagnetic resonance (EPR) and chronoamperometry proposed that the system is a typical singlet oxygen (O) -dominated non-radical pathway.

Automated high-resolution 3D inspection methods for sealant applications in aerospace based on line structured light.

Gluing is a critical step in aircraft sealing assembly, with glue profile inspection serving as the final quality assurance measure to ensure consistency and accuracy of the sealant coating, allowing timely detection and correction of defects to maintain assembly integrity and safety. Currently, existing glue inspection systems are limited to basic inspection capabilities, lack result digitization, and exhibit low efficiency. This paper proposes a 3D inspection technology for sealant coating quality based on line-structured light, enabling automated and high-precision inspection of sealant thickness, sealant width, positional accuracy, and overlap joint sealant contour through geometric computation.

Primary gross tumor volume is prognostic and suggests treatment in upper esophageal cancer.

Background: To aid clinicians strategizing treatment for upper esophageal squamous cell carcinoma (ESCC), this retrospective study investigated associations between primary gross tumor volume (GTVp) and prognosis in patients given surgical resection, radiotherapy, or both resection and radiotherapy.

Methods: The population comprised 568 patients with upper ESCC given definitive treatment, including 238, 216, and 114 who underwent surgery, radiotherapy, or combined radiotherapy and surgery. GTVp as a continuous variable was entered into the multivariate Cox model using penalized splines (P-splines) to determine the optimal cutoff value.

Association of IDH mutation and 1p19q co-deletion with tumor immune microenvironment in lower-grade glioma.

Although the successful clinical trials of immunotherapy show promising strategies for many cancers, its application in glioma has lagged in comparison with the progress seen in other cancers. Both isocitrate dehydrogenase (IDH) mutations and 1p/19q codeletions are critical molecular alterations affecting therapeutic response in lower-grade glioma (LGG). The systematic and comprehensive characterization of the immunological phenotypes with different molecular subtypes is key to improving our understanding and application of immunotherapies in LGG.

Fibulin-3 affects vascular endothelial function and is regulated by angiotensin II.

Objective: The aim of the present study was to investigate the effect of fibulin-3 on vascular endothelial function, and to explore the relevant underlying mechanism with regard to the involvement of angiotensin II (AngII).

Methods: One hundred and eight patients with essential hypertension (EH) and 31 controls were included to measure the flow-mediated dilatation (FMD). Serum fibulin-3 and AngII were examined using enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay.

A three-lncRNA signature predicts clinical outcomes in low-grade glioma patients after radiotherapy.

Although radiation therapy (RT) plays a critical role in the treatment of low-grade glioma (LGG), many patients suffer from adverse effects without experiencing survival benefits. In various carcinomas, long non-coding RNAs (lncRNAs) contribute to pathogenic processes, including tumorigenesis, metastasis, chemoresistance, and radioresistance. Currently, the role of lncRNAs in the radiosensitivity of LGG is largely unknown.

as a Novel Diagnostic and Prognostic Biomarker for Clear Cell Renal Cell Carcinoma.

Clear cell renal cell carcinoma (ccRCC) is a highly aggressive disease and ∼30% of the patients are diagnosed at the metastatic stage. Even with new targeted therapies, the average progression-free survival and overall survival (OS) rates are dismal. Thus, biomarkers for early detection and progression could improve disease outcome.

Contextual interference enhances motor learning through increased resting brain connectivity during memory consolidation.

Increasing contextual interference (CI) during practice benefits learning, making it a desirable difficulty. For example, interleaved practice (IP) of motor sequences is generally more difficult than repetitive practice (RP) during practice but leads to better learning. Here we investigated whether CI in practice modulated resting-state functional connectivity during consolidation.

Methods: Between November 2013 and November 2015, all patients who had flow diverters placed for distal internal carotid artery (ICA) aneurysms were reviewed. Patients in whom the stent was placed across the ostia of the ophthalmic artery (OphA) and anterior choroidal artery (AChA) were enrolled.

Benefit of interleaved practice of motor skills is associated with changes in functional brain network topology that differ between younger and older adults.

Practicing tasks arranged in an interleaved manner generally leads to superior retention compared with practicing tasks repetitively, a phenomenon known as the contextual interference (CI) effect. We investigated the brain network of motor learning under CI, that is, the CI network, and how it was affected by aging. Sixteen younger and 16 older adults practiced motor sequences arranged in a repetitive or an interleaved order over 2 days, followed by a retention test on day 5 to evaluate learning.
