Objects: Taurine exhibits protective effects in the context of cardiovascular pathophysiology. A range of evidence suggests that hypertension activates inflammatory responses and oxidative stress in the paraventricular nucleus (PVN), elevating the arterial tone and sympathetic activity, while it induces gut-brain axis dysfunction in the context of hypertension. However, the mechanism underlying taurine's anti-hypertensive effects via the gut-brain axis remains unclear.

Coronary microembolization (CME) is defined as atherosclerotic plaque erosion, spontaneous rupture, or rupture of the plaque while undergoing interventional therapy resulting in the formation of tiny emboli that obstruct the coronary microcirculatory system. For percutaneous coronary intervention, CME is a major complication, with a periprocedural incidence of up to 25%. Recent studies have demonstrated that regulatory cell death (RCD) exerts a profound influence on CME through its modulation of inflammatory responses, oxidative stress, cell death, and angiogenesis.

Key Laboratory of Biomedical Information Engineering of Ministry of Education, School of Life Science and Technology, Xi'an Jiaotong University, Xi'an, 710049, Shanxi Province, China.

Promoting vascular endothelial cell regeneration can enhance recovery from cerebral ischemia reperfusion injury (CIRI), but there is a lack of bioinformatic studies on angiogenesis-related biomarkers in CIRI. In this study, we utilized the GSE97537 and GSE61616 datasets from GEO to identify 181 angiogenesis-related genes (ARGs) and analyzed differentially expressed genes (DEGs) between CIRI and control groups. We converted ARGs to 169 rat homologues and intersected them with DEGs to find DE-ARGs.

Metformin (Met) is one of the most commonly prescribed first-line drugs for diabetes treatment. However, it has several issues, including low bioavailability, therapeutic platform, and side effects at high doses. In order to improve the therapeutic efficiency of Met, this study proposes a strategy of using Met and curcumin (Cur) to prepare Cur-Zn(II)-Met infinite coordination polymer nanoparticles (CM ICP NPs), and combining this with intraperitoneal injections, for the treatment of diabetic mice.

This study aimed to investigate the molecular mechanisms of periodontitis and identify key immune-related biomarkers using machine learning and Mendelian randomization (MR). Differentially expressed gene (DEG) analysis was performed on periodontitis datasets GSE16134 and GSE10334 from the Gene Expression Omnibus (GEO) database, followed by weighted gene co-expression network analysis (WGCNA) to identify relevant gene modules. Various machine learning algorithms were utilized to construct predictive models, highlighting core genes, while MR assessed the causal relationships between these genes and periodontitis.

Current chemotherapeutic efficacy is limited by the rapid development of multidrug resistance (MDR) in hepatocellular carcinoma (HCC). In this study, 66 MDR-related hub genes in drug-resistant HCC were identified through combined analysis of differential expressed genes (DEGs), gene functional enrichment, Cox proportional regression, weighted gene co-expression network analysis (WGCNA) and protein-protein interaction (PPI) network construction. A prognostic risk model was established through the LASSO-Cox regression analysis.

Background: Previous epidemiological studies have yielded inconclusive results regarding the causality between blood metabolites and the risk of gastric cancer (GC). To address this shortcoming, we conducted a two-sample Mendelian randomization (MR) study, combined with metabolomics techniques, to elucidate the causality between 486 genetically predicted blood metabolites and GC.

Methods: MR analysis and metabolomics techniques such as ultra-high performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS) and gas chromatography/tandem mass spectrometry (GC-MS/MS) technologies were employed to assess the causality of 486 genetically predicted blood metabolites on the risk of GC.

Glioma is one of the most common primary malignant tumors of the central nervous system, and the prognosis is getting worse with the improvement of tumor grade. In recent years, with the in-depth study of the disease, researchers have found that microvascular mimicry seems to be the key factor of poor prognosis, but its specific mechanism has not been thoroughly studied, and the expression of microvascular mimicry in high-grade gliomas is closely related to the expression of NDRG1 gene. This research project is expected to control the occurrence and development of HGG by exploring the factors that affect the expression of NDRG1 gene.
