TL;DR: High-flexibility, high-toughness double-cross-linked (DC) chitin hydrogels are prepared through a sequential chemical and physical cross-linkings strategy with relatively high stiffness, high toughness, and toughness recoverability.
Abstract: High-flexibility, high-toughness double-cross-linked (DC) chitin hydrogels are prepared through a sequential chemical and physical cross-linkings strategy. The incorporation of chemically and physically cross-linked domains imbues the DC chitin hydrogels with relatively high stiffness, high toughness, and toughness recoverability.

TL;DR: A chimeric peptide, PpIX-1MT, is synthesized, which integrates photosensitizer Ppix with immune checkpoint inhibitor 1MT via a caspase-responsive peptide sequence, Asp-Glu-Val-Asp (DEVD), to realize a cascaded synergistic effect that could inhibit both primary and lung metastasis tumor effectively.
Abstract: Metastasis and recurrence are two unavoidable and intractable problems in cancer therapy, despite various robust therapeutic approaches. Currently, it seems that immunotherapy is an effective approach to solve these problems, but the high heterogeneity of tumor tissue, inefficient presentation of tumor antigen, and deficient targeting ability of therapy usually blunt the efficacy of immunotherapy and hinder its clinical application. Herein, an approach based on combining photodynamic and immunological therapy was designed and developed. We synthesized a chimeric peptide, PpIX-1MT, which integrates photosensitizer PpIX with immune checkpoint inhibitor 1MT via a caspase-responsive peptide sequence, Asp-Glu-Val-Asp (DEVD), to realize a cascaded synergistic effect. The PpIX-1MT peptide could form nanoparticles in PBS and accumulate in tumor areas via the enhanced penetration retention effect. Upon 630 nm light irradiation, the PpIX-1MT nanoparticles produced reactive oxygen species, induced apoptosis of cance...

TL;DR: Functionalized magnetic materials (FMMs) have been widely used in analytical chemistry and have shown many advantages including easy surface modification, easy operation, and high extraction efficiency.
Abstract: Functionalized magnetic materials (FMMs) have been widely used in analytical chemistry. For sample preparation, FMMs show many advantages including easy surface modification, easy operation and high extraction efficiency. In this review, we describe the recent advances in FMMs in sample preparation. We first discuss their synthesis and characterization. We then focus on their application to enrichment of biological macromolecules of the proteome and contaminants in foods. Finally, we outline the prospects for FMMs in sample preparation.

TL;DR: In this article, a cross-linking quaternized cellulose and carboxymethyl cellulose with epichlorohydrin (ECH) in NaOH aqueous solution was used to synthesize hydrogels with pH and salt responsive properties.
Abstract: Ampholytic hydrogels with pH and salt responsive properties have been synthesized by cross-linking quaternized cellulose (QC) and carboxymethyl cellulose (CMC) with epichlorohydrin (ECH) in NaOH aqueous solution. The swelling behaviors of the QC/CMC hydrogels were studied as a function of the polymer composition, pH, and salt concentration. The equilibrium swelling ratio of the hydrogel in ultrapure water strongly depended on the composition, and increased dramatically from 8.6 to 498 g/g with the change of the weight ratio of QC to CMC from 3:1 to 1:3 (w/w). The hydrogel (Gel32) consisted of QC and CMC in the ratio of 3:2 (w/w) had the minimum swelling ratio, and it was electrically neutral. The results from ζ-potential experiments were in good agreement with the theoretically calculated stoichiometry for balanced charge, confirming that the weight ratio of QC and CMC was 1.5, corresponding to Gel32. Furthermore, all hydrogels exhibited excellent pH sensitivity in the range of pH from 1 to 13 and shrunk ...

TL;DR: It is shown that DBH can efficiently bind with BSA and be transported to the focuses needed and is supported by a docking study using a BSA crystal model.
Abstract: Hydrazone derivatives possess potential antitumor activities based on modulation of the iron metabolism in cancer cell. A novel hydrazone, N′-(2,4-dimethoxybenzylidene)-2-hydroxybenzohydrazide (DBH), has been synthesized and characterized, which is an analogue of 311 possessing potent anticancer activity. The interactions between DBH and bovine serum albumin (BSA) have been investigated systematically by fluorescence, molecular docking, circular dichroism (CD), UV−vis absorption, and electrochemical impedance spectroscopy (EIS) methods under physiological conditions. The fluorescence quenching observed is attributed to the formation of a complex between BSA and DBH, and the reverse temperature effect of the fluorescence quenching has been found and discussed. The primary binding pattern is determined by hydrophobic interaction occurring in Sudlow’s site I of BSA. DBH could slightly change the secondary structure and induce unfolding of the polypeptides of protein. An average binding distance of ∼4.0 nm ha...
