Sensitive detection and selective determination of the physiologically important chemicals involved in brain function have drawn much attention for the diagnosis and treatment of brain diseases and neurological disorders. This paper reports a novel method for fabrication of enzyme entrapped-conducting polymer nanofibers that offer higher sensitivity and increased lifetime compared to glucose sensors that are based on conducting polymer films.

Objectives: Patients with connective tissue diseases (CTD) have a high incidence of cardiac involvement, which often presents insidiously and can progress rapidly, making it one of the leading causes of death. Multiparametric cardiovascular magnetic resonance (CMR) provides a comprehensive quantitative evaluation of myocardial injury and is emerging as a valuable tool for detecting cardiac involvement in CTD. This study aims to investigate the correlations between CMR features and serological biomarkers in CTD patients, assess their potential clinical value, and further explore the impact of pre-CMR immunotherapy intensity on CMR-specific parameters, thereby evaluating the role of CMR in the early diagnosis of CTD-related cardiac involvement.

Developing solid electrolytes with high ionic conductivity, a high voltage window, low flammability, and excellent interface compatibilities with both the anode and cathode for lithium-metal batteries is still a great challenge but highly desirable. Herein, we achieve this target through an in situ copolymerization of vinyl ethylene carbonate (VEC) together with acrylonitrile (AN) under fitting ratios inside a porous polyacrylonitrile (PAN) fiber membrane doped with flame-retardant decabromodiphenyl ethane (DBDPE) molecules. The received fiber-reinforced polycarbonate-based composite electrolyte with an ultrathin thickness of 13 μm exhibits good internal interfacial compatibility because of the same AN structure and superior flame-retardant performance due to the doped DBDPE molecules.

Organic solar cells (OSCs) with p-i-n architecture usually exhibit decent efficiency due to the easily tunable energy levels of organic interfacial layers (ILs). However, their operational lifetime is limited by the morphological instability of organic ILs especially the electron-transporting layer (ETL) that shows strong self-aggregation tendency. Besides, organic ETLs are confronted with significant challenges including large batch-to-batch variations and high costs.

Stimuli-responsive (multiphase) coacervates deserve significant attention as cell-like entities that can adapt to their environment and undergo morphological reconfiguration. In this study, a tandem-triggered transition system is presented that enables the transformation of single-phase coacervates into multiphase structures through the sequential application of two external stimuli: pH and salt concentration. A polyanion containing acid-labile amide bond is incorporated into the membrane-less coacervates.

Objectives: Norvir oral powder [ritonavir (RTV)] employs polyvinylpyrrolidone/vinyl acetate as the polymer to formulate an amorphous solid dispersion. Its oral absolute bioavailability is 70% in the fasted state, and it has negative food effects. The aim of this study was to perform in vitro dissolution of Norvir powder and Wagner-Nelson deconvolution of data under fasted, moderate fat, and high fat conditions in order to elucidate the relevance of dissolution testing.
