The Latest Applications of Carbon-Nitride-Based Materials for Combination Treatment of Cancer.

Carbon-nitride-based (CN-based) materials have shown great potential in combination therapy in recent years. Due to their outstanding biocompatibility, ease of modification, and adjustable band-gap position, CN-based materials can be applied as photosensitizers in photodynamic therapy (PDT) and light-driven water-splitting catalysts in gas therapy. After doping with other elements, the photocatalytic performance of CN-based materials will be enhanced, and more interesting functions will be obtained.

Red fluorescent AIE bioprobes with a large Stokes shift for droplet-specific imaging and fatty liver diagnosis.

Lipid droplets (LDs) as spherical dynamic subcellular organelles, play an important role in various cellular functions such as protein degradation, lipid metabolism, energy storage, signal transduction, and membrane formation. Abnormal function of LDs will lead to a series of diseases and hence monitoring the status of LDs is particularly important. In this study, we synthesized a water-insoluble red fluorescent emitting small molecule fluorescent probe (TPE-TCF), which exhibited aggregation-induced emission (AIE) properties and enabled highly selective real-time imaging of LDs (Pearson's R value was 0.

Identification and characterization of HP-B1083-derived β-glucuronidase and its application for baicalin biotransformation.

Baicalein, showing higher bioavailability and stronger pharmacological activity, can be obtained via a β-glucuronidase (GUS)-catalyzed transformation of baicalein 7-O-β-D-glucuronide (baicalin). Recently, we have found that the fermentation broth of HP-B1083 can efficiently convert baicalin to baicalein. In this study, the HP-B1083-derived enzyme involved in baicalin biotransformation was identified and characterized.

Self-Produced O CNs-Based Nanocarriers of DNA Hydrophobization Strategy Triggers Photodynamic and Mitochondrial-Derived Ferroptosis for Hepatocellular Carcinoma Combined Treatment.

Hypoxia can aggravate tumor occurrence, development, invasion, and metastasis, and greatly inhibit the photodynamic therapy (PDT) effect. Herein, carbon nitride (CNs)-based DNA and photosensitizer co-delivery systems (BPSCNs) with oxygen-producing functions are developed to address this problem. Selenide glucose (Seglu) is used as the dopant to prepare red/NIR-active CNs (SegluCNs).

Nanogalvanic Cells Release Highly Reactive Electrons in Tumors to Effectively Eliminate Tumors.

External stimuli triggering chemical reactions in cancer cells to generate highly reactive chemical species are very appealing for cancer therapy, in which external irradiation activating sensitizers to transfer energy or electrons to surrounding oxygen or other molecules is critical for generating cytotoxic reactive species. However, poor light penetration into tissue, low activity of sensitizers, and reliance on oxygen supply restrict the generation of cytotoxic chemical species in hypoxic tumors, which lowers the therapeutic efficacy. Here, this work presents galvanic cell nanomaterials that can directly release highly reactive electrons in tumors without external irradiation or photosensitizers.

Analysis of prescription compliance and influencing factors in cardiac rehabilitation after surgery in children with congenital heart disease based on generalized trust theory.

Aims: To understand the compliance, influencing factors, and action path of family cardiac rehabilitation exercise prescriptions for children after congenital heart disease surgery.

Methods And Results: A random sampling method was used to select 200 paediatric patients and their parents from a paediatric hospital in Shanghai. Among them, 57 cases (28.

Tumor Microenvironment Triggered the Synthesis of an Excellent Sonosensitizer in Tumor for Sonodynamic Therapy.

An ultrasound-triggered sonodynamic therapy has shown great promise for cancer therapy. However, its clinical applications are very limited because the traditional sonosensitizers tend to suffer from very poor efficiency combined with low retention in cancer cells and low tumor selectivity. Therefore, sonosensitizers with higher effectivity, higher tumor cell retention, and higher tumor cell specificity are highly required.

Visible-light driven degradation of ibuprofen using abundant metal-loaded BiVO₄ photocatalysts.

An efficient method for the degradation of ibuprofen as an aqueous contaminant was developed under visible-light irradiation with as-prepared bismuth vanadate (BiVO4) catalysts. The metal-loaded catalysts Cu-BiVO4 and Ag-BiVO4 were synthesized using a hydrothermal process and then a wet-impregnation method. All of the materials were fully characterized by X-ray diffraction, scanning electron microscopy, UV-vis diffuse reflectance spectroscopy, X-ray photoelectron spectroscopy and BET surface area.
