Nanocellulose-enhanced smart film for the accurate monitoring of shrimp freshness via anthocyanin-induced color changes.

Smart films allow consumers to visually determine food freshness. We aimed to improve the surface contact area of gas permeation in anthocyanin (AH)-induced smart films by introducing nanocellulose (NC) prepared by sulfuric acid (CNSA), citric acid (CNCA), and TEMPO (CNF) to improve their sensitivity. The film matrix was composed of PVA.

Synthesis of carbon dots with strong luminescence in both dispersed and aggregated states by tailoring sulfur doping.

Carbon dots (CDots), a class of environmentally friendly carbon-based luminescent nanomaterial, have been applied in a wide variety of fields, including bioimaging and light-emitting diodes (LEDs). Prior to these applications, however, CDots usually require modifications because some of its limitations (e.g.

SNHG17/miR-384/ELF1 axis promotes cell growth by transcriptional regulation of CTNNB1 to activate Wnt/β-catenin pathway in oral squamous cell carcinoma.

Increasing evidence proved the abnormal expression of long non-coding RNAs (lncRNAs) in various human malignancies, including oral squamous cell carcinoma (OSCC). Nevertheless, limited explorations concern the role of lncRNA small nucleolar RNA host gene 17 (SNHG17) in OSCC. Herein, SNHG17 was disclosed to be remarkably upregulated in OSCC cell lines and promoted OSCC cell growth.

[Roles of autophagy onself-renewal and differentiation of mesenchymal stem cells].

Mesenchymal stem cells (MSCs), which have the potential of self-replication and differentiation, are a very valuable cell source for stem cell-based medical therapy. Their application has opened up a new way for disease research. Although MSCs can maintain cell stemness through self-renewal, with the prolongation of cell passage and culture time, the stemness of MSCs gradually decays, and the cell aging and differentiation potential decreases gradually.

The Down-Regulation of lncRNA PCAT18 Promotes the Progression of Gastric Cancer via MiR-107/PTEN/PI3K/AKT Signaling Pathway.

Purpose: LncRNAs are important regulators in cancers. In this study, we investigated the role of lncRNA PCAT18 in gastric cancer (GC).

Patients And Methods: The level of PCAT18 in GC tissues and cells was determined by qRT-PCR.

WO3-x Nanoplates Grown on Carbon Nanofibers for an Efficient Electrocatalytic Hydrogen Evolution Reaction.

The search for non-noble metal catalysts with high activity for the hydrogen evolution reaction (HER) is crucial for efficient hydrogen production at low cost and on a large scale. Herein, we report a novel WO3-x catalyst synthesized on carbon nanofiber mats (CFMs) by electrospinning and followed by a carbonization process in a tubal furnace. The morphology and composition of the catalysts were tailored via a simple method, and the hybrid catalyst mats were used directly as cathodes to investigate their HER performance.
