The low electrocatalytic activity of pristine graphite felt (GF) electrodes towards V(II)/V(III) and V(IV)/V(V) redox couples poses a significant challenge in vanadium redox flow batteries (VRFBs). Here, Metal-organic frameworks (MOFs) containing Cu, Co, N, and S are proposed as precursors for the construction of metal and nonmetal co-doped GF electrodes, which exhibit enhanced catalytic activity compared to pristine GF electrodes. The synergistic effect of the metal and nonmetal components results in the N,S/Cu,Co@GF electrode exhibiting increased hydrophilicity, electrochemical reactivity, and reversibility.

Aberrant expression of the SRY-related HMG-box (SOX) genes contributes to tumor development and progression. This research aimed to identify the regulation of the SOX genes in stomach adenocarcinoma (STAD). Expression profiles downloaded from The Cancer Genome Atlas (TCGA) were conducted to analyze the expression and function of the SOX genes.

Here, we report a urinary metabolomic study on a cohort of CRC patients ( =67) and healthy controls ( =21) using ultraperformance liquid chromatography triple quadrupole mass spectrometry. Pathway analysis showed that a series of pathways that belong to amino acid metabolism, carbohydrate metabolism, and lipid metabolism were dysregulated, for instance the glycine, serine and threonine metabolism, alanine, aspartate and glutamate metabolism, glyoxylate and dicarboxylate metabolism, glycolysis, and TCA cycle.

However, approved small molecule immunomodulators often suffer from ineffective response rates and severe off-target toxicity. ATP occupies a crucial role in energy metabolism of components that form the tumor microenvironment (TME) and influences cancer immunosurveillance.

Common clinical symptoms are abdominal discomfort and bleeding signs, which frequently present slow-onset in reported cases. Herein, we report a case of gastric PF presenting as acute onset and with pyemia accom-panying tumor rupture.
View Article and Find Full Text PDFAlthough promising, the efficiency of aggregation-induced emission luminogens (AIEgens)-based photodynamic therapy (PDT) is limited by cellular glutathione (GSH). GSH is not a terminal reducing agent but it can be oxidized and subsequently reduced to its original state by reductases to further participate in antioxidant activity. It is therefore imperative to control GSH for effectively inducing oxidation within tumor cells.

The cathode was synthesized using the one-pot electrodeposition method and was used to in-situ generate HO through the two-electron reduction of oxygen. The produced HO was then catalytically converted into ·OH and ·O simultaneously.

The development of novel radiosensitizer with high selectivity and controllability is highly desirable. CO gas could cause damage to mitochondria and thus enhance RT effect. Controlled delivery of CO in tumor is important both to achieve high-efficiency of CO gas therapy and to decrease the risk of CO poisoning.
View Article and Find Full Text PDFFew-layered black phosphorus (FP) has recently attracted extensive research in the energy and materials fields. However, because of its chemically unstable nature under ambient conditions, very positive hydrogen adsorption energy and less active sites, FP has not been an efficient catalyst for the hydrogen evolution reaction (HER). In this research, we have developed a new strategy to overcome FP's drawbacks and to make it an active and stable HER catalyst.

The restriction of a tumor's energy supply is proven to be an effective means of treatment. Glucose oxidase (GOx), an enzyme that catalyzes the conversion of glucose to glucolactone, producing oxygen and hydrogen peroxide in the process, has proved useful in this regard. However, hypoxia, which is implicated in tumor growth, has been found to mediate resistance to this type of tumor starvation.
