High Abundance of Unusual High Mannose -Glycans Found in Beans.

High mannose -glycans extracted from eight different beans (black bean, soybean, pea, white kidney bean, pinto bean, mung bean, white hyacinth bean, and red bean) were studied using the state-of-the-art mass spectrometry method logically derived sequence tandem mass spectrometry (LODES/MS). These beans show very similar -glycan isomer profiles: one isomer of ManGlcNAc and ManGlcNAc, two isomers of ManGlcNAc, three isomers of ManGlcNAc, and five isomers of ManGlcNAc were found. Isomers not predicted by current -glycan biosynthetic pathways were found in all beans, indicating the possibility of alternative biosynthetic pathways in these plants.

Photothermal-responsive lignin-based polyurethane with mechanically robust, fast self-healing, solid-state plasticity and shape-memory performance.

In light of the depletion of petrochemical resources and increase in environmental pollution, there has been a significant focus on utilizing natural biomass, specifically lignin, to develop sustainable and functional materials. This research presents the development of a lignin-based polyurethane (DLPU) with photothermal-responsiveness by incorporating lignin and oxime-carbamate bonds into polyurethane network. The abundant hydrogen bonds between lignin and the polyurethane matrix, along with its cross-linked structure, contribute to DLPU's excellent mechanical strength (30.

Chromatograms and Mass Spectra of High-Mannose and Paucimannose -Glycans for Rapid Isomeric Identifications.

-Linked glycosylation is one of the most essential post-translational modifications of proteins. However, -glycan structural determination remains challenging because of the small differences in structures between isomers. In this study, we constructed a database containing collision-induced dissociation MS mass spectra and chromatograms of high-performance liquid chromatography for the rapid identification of high-mannose and paucimannose -glycan isomers.

Engineered bacteria launch and control an oncolytic virus.

The ability of bacteria and viruses to selectively replicate in tumors has led to synthetic engineering of new microbial therapies. Here we design a cooperative strategy whereby bacteria transcribe and deliver the Senecavirus A RNA genome inside host cells, launching a potent oncolytic viral infection. "Encapsidated" by bacteria, the viral genome can further bypass circulating antiviral antibodies to reach the tumor and initiate replication and spread within immune mice.

Identification of the High Mannose -Glycan Isomers Undescribed by Conventional Multicellular Eukaryotic Biosynthetic Pathways.

-linked glycosylation is one of the most important post-translational modifications of proteins. Current knowledge of multicellular eukaryote -glycan biosynthesis suggests high mannose -glycans are generated in the endoplasmic reticulum and Golgi apparatus through conserved biosynthetic pathways. According to conventional biosynthetic pathways, four ManGlcNAc isomers, three ManGlcNAc isomers, and one ManGlcNAc isomer are generated during this process.

Knowledge mapping of nano drug delivery systems across blood - Brain barrier from 1996 to 2022: A bibliometric analysis.

Background: The blood-brain barrier (BBB) is a natural physiological barrier that protects the central nervous system from foreign substances and limits the delivery of drugs to the brain. Nanotechnology has opened up new possibilities for drug delivery in the brain. Over several decades, various Nanoparticle Drug Delivery Systems (NDDS) that can cross the BBB have been developed for targeted delivery in the brain.

3D printed heterogeneous hybrid hydrogel scaffolds for sequential tumor photothermal-chemotherapy and wound healing.

Surgical resection remains the mainstay of melanoma treatment. However, due to the difficulties in controlling tumor recurrence and wound healing simultaneously, high postoperative recurrence rates and wound reconstruction remain the most significant challenges. As a result, a heterogeneous hybrid hydrogel scaffold was designed in this work to achieve sequential photothermal therapy and chemotherapy for melanoma recurrence inhibition and wound healing.

Development of a versatile antimicrobial anti-inflammatory hydrogel dressing that eliminates concern over antibiotic resistance is urgently needed but remains an elusive goal. Our research, described herein, the design and fabrication of a new family of supramolecular hydrogels based on hydroxypropyl chitosan (HPCS) and poly(N-isopropylacrylamide) (PNIPAM) may prove to be that goal.

Fabrication of Au Nanoparticle Arrays on Flexible Substrate for Tunable Localized Surface Plasmon Resonance.

In this work, Au nanoparticle (AuNP) arrays on shape memory polyurethane (SMPU) substrates serve as flexible materials for tunable localized surface plasmon resonance (LSPR). AuNP arrays prepared by diblock copolymer self-assembly are transferred from rigid silicon wafers onto flexible SMPU substrates with ultrasonic treatment rather than peeling off directly. The resultant AuNP array SMPU films have excellent mechanical properties and stable thermodynamic properties.

Mesoscopic simulations of drug-loaded diselenide crosslinked micelles: Stability, drug loading and release properties.

Intelligent reversible crosslinked micelles that have a good balance of structure stability in normal tissue and controlled drug release responded to the tumor microenvironment are highly promising novel drug delivery systems. However, to date, there have been very few reports about mesoscale simulations of drug-loaded polymeric reversible crosslinked micelles. Here, dissipative particle dynamics (DPD) simulation, the nearest-neighbor bonding principle, and the nearest media-bead bond breaking principle were used to investigate the influence of physiological environment along with low tumor pH and reduction microenvironment on the stability and doxorubicin (DOX) distribution of the star polymer [PCL-b-P(HEMA-Se-Se˜)-b-PPEGMA] diselenide crosslinked micelles with different diselenide crosslinking levels (CLs).

Controlled construction of gold nanoparticles in situ from β-cyclodextrin based unimolecular micelles for in vitro computed tomography imaging.

The development of nanomaterials as highly efficient contrast agents for tumor computed tomography (CT) imaging still remains a huge challenge. In this study, a novel and facile approach to fabricate unimolecular micelles-stablized gold nanoparticles (AuNPs) without external reductant for in vitro targeted CT imaging was described. Amphiphilic 21-arm star-like polymers β-cyclodextrin-g-{poly(2-(dimethylamino)ethyl methacrylate)-poly(2-hydroxyethyl methacrylate)-poly[poly(ethylene glycol) methyl ether methacrylate]} [β-CD-g-(PDMA-b-PHEMA-b-PPEGMA)] was firstly synthesized and proved to form unimolecular core-middle layer-shell-type micelles in water through experimental and computer simulation results.

Synergistic effects of boron-doped silicone resin and a layered double hydroxide modified with sodium dodecyl benzenesulfonate for enhancing the flame retardancy of polycarbonate.

To improve the flame retardancy of polycarbonate (PC), a novel and environmentally friendly flame retardant was synthesized by combining boron-doped silicone resin (BSR) with a layered double hydroxide (LDH) modified with sodium dodecyl benzenesulfonate (SDBS) which was denoted as DBS-LDH/BSR. The structure of the hybrid was characterized by Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS), which indicated that BSR was successfully combined with DBS-LDH. X-ray diffraction (XRD) studies showed that the reaction of BSR occurred only on the surface of DBS-LDH.

Silver nanowires (AgNWs) were chemically etched to significantly increase the surface roughness and then self-assembled on the liquid/gas interfaces via the interfacial assembly method to obtain aligned chemically etched silver nanowire films. The as-fabricated silver nanowire films were used as novel surface-enhanced Raman scattering (SERS) substrates. The morphologies and plasmon characteristics of the substrates were investigated using multiple measurement methods.

Fabrication of Ordered Nanopattern by using ABC Triblock Copolymer with Salt in Toluene.

Ordered nanopatterns of triblock copolymer polystyrene-block-poly(2-vinylpyridine)-block- poly (ethylene oxide)(PS-b-P2VP-b-PEO) have been achieved by the addition of lithium chloride (LiCl). The morphological and structural evolution of PS-b-P2VP-b-PEO/LiCl thin films were systematically investigated by varying different experimental parameters, including the treatment for polymer solution after the addition of LiCl, the time scale of ultrasonic treatment and the molar ratio of Li ions to the total number of oxygen atoms (O) in PEO block and the nitrogen atoms (N) in P2VP block. When toluene was used as the solvent for LiCl, ordered nanopattern with cylinders or nanostripes could be obtained after spin-coating.

Metal ion induced-assembly of amylose in aqueous solution.

Cu(2+)/amylose assemblies of various sizes were prepared through the Cu(2+) ion induced-assembly of amylose. These assembly structures were characterized via transmission electronic microscopy (TEM), scanning electronic microscopy (SEM), dynamic light scattering (DLS), (1)H NMR analysis, fluorescence spectroscopy (FL) and UV-vis absorption spectroscopy (UV-vis). The results from these characterizations revealed the existence of a complexation effect and/or a bridging effect between the hydroxyl groups of amylose and Cu(2+) ions, and that the formation of the hydrophobic domains promoted the formation of Cu(2+)/amylose assemblies.
