Carbazole-derived self-assembled monolayers (SAMs) are promising materials for hole-extraction layer (HEL) in conventional organic photovoltaics (OPVs). Here, a SAM Cbz-2Ph derived from 3,6-diphenylcarbazole is demonstrated. The large molecular dipole moment of Cbz-2Ph allows the modulation of electrode work function to facilitate hole extraction and maximize photovoltage, thus improving the OPV performance.

Article Synopsis
  • The study examined the effects of ceftriaxone and adipose-derived mesenchymal stem cells (ADMSCs) on protecting the spinal cord from acute spinal infection (ASI) in rats.
  • Results showed that the combination treatment of ceftriaxone and ADMSCs led to significantly lower inflammatory markers and bacterial counts compared to the individual treatments, indicating better inflammation control and tissue preservation.
  • By day 28, the combination therapy demonstrated superior results in protecting vertebral bone and spinal cord integrity compared to each treatment alone, suggesting a potential therapeutic strategy for ASI.

Introduction: In patients with chronic coronary syndromes (CCS), the benefit of percutaneous coronary intervention (PCI) added to optimal medical therapy (OMT) remains unclear. The indication to PCI may be driven either by angiographic evaluation or ischemia assessment, thus depicting different potential strategies which have not yet been thoroughly compared.

Methods: Randomized controlled trials (RCTs) comparing OMT versus PCI angio-guided or versus PCI non-invasive or invasive ischemia guided were identified and compared via network meta-analysis.

Esophageal squamous cell carcinoma (ESCC) remains a significant global health challenge, being the sixth leading cause of cancer mortality with pronounced geographic variability. The incidence rates range from 125 per 100,000 in northern China to 1-1.5 per 100,000 in the United States, driven by environmental and lifestyle factors such as tobacco and alcohol use, dietary habits, and pollution.

Introduction: Long-term data on metachronous advanced adenoma (AA) recurrence after endoscopic submucosal dissection (ESD) remain scarce, leading to a lack of a standardized surveillance strategy. This study aims to evaluate the long-term risk of recurrent AA after ESD.

Materials And Methods: A longitudinal retrospective cohort study with propensity-score matching was conducted in a tertiary hospital in Hong Kong.
