Article Abstract
Isobenzofurans (IBF)s have seen widespread use in the synthesis of both natural products and polycyclic aromatic hydrocarbons. There are few examples that have two IBF entities linked in a fused aromatic ring system. Here we present the synthesis and characterization of a bis(IBF), 2,7-di(tert-butyl)pyreno[4,5-c:9,10-c']difuran. Reaction with bis(maleimide) dienophiles gives pyrenophanes. The solid-state structures of the bis(IBF) and two cyclophanes are discussed.

Background: Metabolic reprogramming is an important hallmark of cervical cancer (CC), and extensive studies have provided important information for translational and clinical oncology. Here we sought to determine metabolic association with molecular aberrations, telomere maintenance and outcomes in CC.
Methods: RNA sequencing data from TCGA cohort of CC was analyzed for their metabolic gene expression profile and consensus clustering was then performed to classify tumors into different groups/subtypes.

Background: Candidiasis, predominantly caused by , poses a significant global health challenge, especially in tropical regions. Nystatin is a potent antifungal agent that is hindered by its low solubility and permeability, limiting its clinical efficacy.
Methods: This study aimed to investigate the potential of a layer-by-layer (LBL) coating system, employing chitosan and alginate, to improve the stability, entrapment efficiency (%EE), and antifungal efficacy of nystatin-loaded liposomes against Candida albicans.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease, the incidence of which continues to rise globally, and existing therapeutic options are limited by low drug bioavailability and systemic side effects. In this study, we systematically investigated the challenges of the special gastrointestinal environment of UC patients for oral drug delivery, such as extreme pH, degradation by digestive enzymes, metabolism of intestinal flora and obstruction of the intestinal mucosal barrier, and summarized the potential of plant-derived Exosome-like Nanovesicles (PELNs) as a novel delivery system. PELNs are produced by plant cells and mainly consist of proteins, RNA, lipids and plant active molecules.

Chronic Obstructive Pulmonary Disease (COPD) is a prevalent chronic respiratory disorder characterized by airway inflammation and irreversible airflow limitation. Its marked heterogeneity and complexity pose significant challenges to traditional clinical assessments in terms of prognostic prediction and personalized management. In recent years, the exploration of biomarkers has opened new avenues for the precise evaluation of COPD, particularly through multi-biomarker prediction models and integrative multimodal data strategies, which have substantially improved the accuracy and reliability of prognostic assessments.

To address the issue of biological pollution in cellulose triacetate (CTA) membranes during seawater desalination, silver (Ag) nanoparticles were incorporated onto the CTA surface using polydopamine (PDA). PDA, which contains phenolic and amino groups, exhibits excellent adhesiveness and provides active sites for the attachment and reduction for Ag nanoparticles. Various characterizations confirm the successful introduction of Ag nanoparticles onto the surface of the PDA-modified CTA (PCTA) membrane and the preservation of CTA microstructures.
