Pure red emission with spectral stability in full iodine-based quasi-2D perovskite films by controlling phase distribution.

Quasi-2D perovskites have emerged as a promising candidate material for displays owing to their high photoluminescence quantum yields and low-cost solution synthesis. However, achieving pure red quasi-2D perovskite films with luminescence centered at 630 nm and a narrow emission band presents a critical challenge for high-definition displays. Herein, by incorporating 18-crown-6 as additives that simultaneously passivate defects and regulate phase distribution, full iodine-based quasi-2D perovskite films with a single red emission peak and spectral stability are designed.

Associations between plasma caspase-1 levels and cardiovascular disease, with the mediating role of metabolic syndrome.

Aims: This study aimed to explore the association between plasma caspase-1 levels and cardiovascular disease (CVD), as well as the potential mediating role of metabolic syndrome (Mets) in the association.

Methods: This study analyzed the UK Biobank Precision Proteomics Project (UKB-PPP), which detected plasma caspase-1 levels in participants. CVD was defined by ICD-9/ICD-10 codes.

Machine learning-based predictive models for perioperative major adverse cardiovascular events in patients with stable coronary artery disease undergoing noncardiac surgery.

Background And Objective: Accurate prediction of perioperative major adverse cardiovascular events (MACEs) is crucial, as it not only aids clinicians in comprehensively assessing patients' surgical risks and tailoring personalized surgical and perioperative management plans, but also for information-based shared decision-making with patients and efficient allocation of medical resources. This study developed and validated a machine learning (ML) model using accessible preoperative clinical data to predict perioperative MACEs in stable coronary artery disease (SCAD) patients undergoing noncardiac surgery (NCS).

Methods: We collected data from 9171 adult SCAD patients who underwent NCS and extracted 64 preoperative variables.

Xinkeshu formula restrains pathological cardiac hypertrophy through metabolic remodeling via AMPK/mTOR pathway.

Background: Xinkeshu (XKS) formula is a patented traditional Chinese medicine used to treat cardiovascular diseases for decades. However, little is known about its potential influence on heart metabolism under pathological conditions.

Purpose: This study sought to explore the potential role of XKS in pathological cardiac hypertrophy, with a focus on metabolic remolding.

The prognostic implication of skip metastasis to lateral neck in patients with papillary thyroid cancer.

Background: Pre-operative detection of skip metastasis in papillary thyroid cancer (PTC) is significant in preventing recurrence. The study aimed to investigate the characteristics and prognosis of skip metastasis to lateral neck in PTC patients by a cross-sectional study.

Methods: Between 2013 and 2016, 494 patients who underwent thyroidectomy for PTC and positive lateral lymph node metastases (LLNM) were retrospectively identified.
