Article Abstract
Chronic kidney disease is often characterized by enhanced activity of the renin-angiotensin system (RAS) and the sympathetic nervous system. Independent of their effect on blood pressure, these systems also contribute to the pathogenesis of both structural and functional cardiovascular abnormalities and contribute importantly to clinical outcome. There is much evidence that the diseased kidneys are of central importance in the pathogenesis of both abnormalities. Inhibitors of the RAS also reduce sympathetic overactivity. Future research should be aimed at addressing the pathophysiological mechanisms causing the enhanced activities. Given the fact that even a small kidney lesion can cause enhanced activity of the RAS and the sympathetic nervous system, it is likely that these pathophysiological mechanisms are operational in more disease conditions, including essential hypertension, heart failure, and obesity/metabolic syndrome.

Ultrasensitive non-enzymatic electrochemical detection of paraoxon-ethyl in fruit samples using 2D TiCT/MWCNT-OH.

This study reports on the development of a highly sensitive non-enzymatic electrochemical sensor based on a two-dimensional TiCT/MWCNT-OH nanocomposite for the detection of paraoxon-based pesticide. The synergistic effect between the TiCT nanosheet and the functionalized multi-walled carbon nanotubes enhanced the sensor's conductivity and catalytic activity. The nanocomposite demonstrates superior electrochemical and electroanalytical performance compared to the pristine TiCT and MWCNT-OH in detecting paraoxon-ethyl in fruit samples (green and red grapes), with a linear response range from 0.

Mass transfer governs the overall catalytic performance of heterogeneous catalysts considerably; however, this fundamental research has often been ignored. Here, macroporous SiO-supported Pt nanoparticle (Pt/SiO-M) and mesoporous SiO-supported Pt nanoparticle (Pt/SiO-m) catalysts were specifically fabricated by a facile thermal reduction step to engineer the resultant Pt nanoparticles showing similar physiochemical properties while possessing completely different porous microstructures exclusively originating from SiO supports. On this basis, a platform to explore the crucial mass transfer difference affecting catalytic activity is then established by systematically practicing industry-important benzene oxidation measurements.

The 2-substituted benzimidazole has emerged as a promising heterocyclic compound in the field of drug design. In pursuit of more sustainable photocatalysts for 2-substituted benzimidazole synthesis, the method for coating FeO with V-doped TiO was presented. On the base of characterizing composition, morphology, and properties, the prepared nano-sized FeO@V/TiO composites were used as a heterogeneous photocatalyst to catalyze the synthesis of 2-substituted benzimidazoles under light.

Metastatic cancer cells undergo metabolic reprogramming, which involves changes in the metabolic fluxes, including endocytosis, nucleocytoplasmic transport, and mitochondrial metabolism, to satisfy their massive demands for energy, cell division, and proliferation compared to normal cells. We have previously demonstrated the ability of two different types of compounds to interfere with linchpins of metabolic reprogramming, Pitstop-2 and 1,6-hexanediol (1,6-HD). 1,6-HD disrupts glycolysis enzymes and mitochondrial function, enhancing reactive oxygen species production and reducing cellular ATP levels, while Pitstop-2 impedes clathrin-mediated endocytosis and small GTPases activity.

Purpose: To conduct a scoping review of the related research on cognitive frailty (CF) in maintenance hemodialysis (MHD) patients, so as to provide a basis for early diagnosis, treatment and intervention of CF in MHD patients.
Methods: Utilizing a scoping review approach, we searched PubMed, Embase, The Cochrane Library, Web of Science, CINAHL, the China Biological Medicine Database (CBM), China National Knowledge Infrastructure (CNKI), Wanfang, and Weipu (VIP) for literature on CF in MHD patients up to October 20, 2024. Two researchers conducted independent screening and data extraction of the literature's fundamental characteristics.
