Microvascular structural changes in esophageal squamous cell carcinoma pathology according to intrapapillary capillary loop types under magnifying endoscopy.

Background: The intrapapillary capillary loop (IPCL) characteristics, visualized using magnifying endoscopy, are commonly assessed for preoperative evaluation of the infiltration depth of esophageal squamous cell carcinoma (ESCC). Japan Esophageal Society (JES) classification is the most widely used classification. Microvascular structural changes are evaluated by magnifying endoscopy for the presence or absence of each morphological factor: tortuosity, dilatation, irregular caliber, and different shapes.

In Situ Growth 3D GDY-NCNTs Nanocomposites for High-Performance Supercapacitors.

New binary carbon composites (GDY-NCNTs and GDY-CNTs) with a three-dimensional porous structure, which are synthesized by an in situ growth method, are adopted in this article. The GDY-NCNTs composites exhibit excellent specific capacitance performance (679 F g, 2 mV s, 139% increase compared to GDY-CNTs) and good cycling stability (with a capacity retention rate of up to 116% after 10000 cycles). The three-dimensional porous structure not only promotes ion transfer and increases the effective specific surface area to improve its specific capacitance performance but also adapts to the volume expansion and contraction during the charging and discharging process to improve its cycling stability.

Increased circulating regulatory T cells and decreased follicular T helper cells are associated with colorectal carcinogenesis.

Objective: Colorectal cancer (CRC) is the third most prevalent cancer worldwide and is associated with high morbidity and mortality rates. Colorectal carcinogenesis occurs via the conventional adenoma-to-carcinoma and serrated pathways. Conventional T helper (Th) and innate lymphoid cells (ILCs) play vital roles in maintaining intestinal homeostasis.

Refurbishment of W/BC multilayers on Si substrate by etching a chromium buffer layer.

In synchrotron facilities, optics with multilayer coatings are used for beam monochromatization, focusing, and collimation. These coatings might be damaged by high heat load, poor film adhesion, high internal stress, or poor vacuum. Optical substrates always need high quality, which is expensive and has a long processing cycle.

Graphdiyne Oxide Quantum Dots: The Enhancement of Peroxidase-like Activity and Their Applications in Sensing HO and Cysteine.

As one of the typical carbon nanomaterials, graphdiyne (GDY) with unique chemical, physical, and electronic properties has a great potential in various fields. Although it is an important member of carbon nanozymes, the research on its intrinsic enzyme mimetic properties and applications is still limited. Herein, graphdiyne oxide quantum dots (GDYO QDs) have been synthesized through oxidative cleavage, which exhibit enhanced peroxidase-like activity with lower and higher than those of most carbon-based nanozymes.

Preparing dangling bonds by nanoholes on graphene oxide nanosheets and their enhanced magnetism.

The effects of dangling bonds on the magnetic properties of graphene oxide (GO) were studied experimentally by creating nanoholes on GO nanosheets. GO with more nanoholes (MHGO) and less nanoholes (LHGO) on graphene oxide nanosheets were synthesized. Results showed that nanoholes brought new dangling bonds for GO and the increase of the dangling bonds on GO could be adjusted by the amounts of the nanoholes on GO.

Lipid- and gut microbiota-modulating effects of graphene oxide nanoparticles in high-fat diet-induced hyperlipidemic mice.

Graphene oxide (GO) suspensions can act as a good dispersant and drug delivery system for effective dispersion and drug sustained release. In this study, we investigated the impact of GO on blood/liver lipids and gut microbiota structure in high-fat diet (HFD)-induced hyperlipidemic mice. Oral administration of GO for 28 days remarkably decreased the lipid levels in blood and liver GO did not decrease the total number of gut bacteria but increased the relative abundance of short-chain fatty acid (SCFA)-producing bacteria such as clusters IV and spp.

Fluorescent activatable gadofullerene nanoprobes as NIR-MR dual-modal in vivo imaging contrast agent.

Dual mode imaging technology is widely developed to achieve the early-stage precision cancer diagnosis. Here we designed a dual-modal magnetic resonance/near infrared fluorescence optical imaging contrast agent (GdF-SS-NIR783) with the fluorescence activatable and safer gadofullerene.

Study on the antigenicity of metallofullerenol: antibody production, characterization, and its enzyme immunoassay application.

With their intriguing structures and properties, metallofullerenols have attracted considerable attention in biological and medical applications. Due to the increasing biomedical interest, effective detection methods are important to monitor and control metallofullerenols. However, the detection of metallofullerenols becomes very difficult after polyhydroxylated modification due to the lack of detectable features.

Metabolizer in vivo of fullerenes and metallofullerenes by positron emission tomography.

Fullerenes (C60) and metallofullerenes (Gd@C82) have similar chemical structure, but the bio-effects of both fullerene-based materials are distinct in vivo. Tracking organic carbon-based materials such as C60 and Gd@C82 is difficult in vivo due to the high content of carbon element in the living tissues themselves. In this study, the biodistribution and metabolism of fullerenes (C60 and Gd@C82) radiolabeled with (64)Cu were observed by positron emission tomography (PET).

Background: Helicobacter pylori (Hp) is a common and potentially curable cause of gastric mucosa lesion. This study investigated the relationship of Hp infection with histological changes in gastric mucosa and gastric cancer in Hp-positive patients compared with Hp-eradication patients followed up for ten years.

Synthesis and characterization of C70-corrole--a new electron transfer dyad.

A new electron transfer dyad, covalently linked C70-corrole, was prepared via C70 and 10-(4-Formylaryl)-5,15-bis(pentafluorophenyl). The structures and the properties of the new material were investigated by HPLC, MALDI-TOF-MS, UV-Vis-NIR spectroscopy, NMR, fluorescence analysis and CV/DPV. The free-energy of C70-corrole calculated by employing the redox potentials and singlet excited-state energy suggested the possibility of electron transfer from the excited singlet state of corrole to the fullerene entity, which agreed with the results of the theoretical calculation.
