Plasma Ionomic Profile and Interaction Patterns in Coronary Artery Disease Patients.

Humans are exposed to various chemical elements that have been associated with the development and progression of diseases such as coronary artery disease (CAD). Unlike previous research, we employed a multi-element approach to investigate CAD patients and those with comorbid conditions such as diabetes (CAD-DM2), high blood pressure (CAD-HBP), or high blood lipids (CAD-HBL). Plasma concentrations of 21 elements, including lithium (Li), boron (B), aluminum (Al), calcium (Ca), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), strontium (Sr), cadmium (Cd), tin (Sn), stibium (Sb), barium (Ba), and lead (Pb), were measured in CAD patients (n = 201) and healthy subjects (n = 110) using inductively coupled plasma-mass spectrometry (ICP-MS).

DNA methylation and single-nucleotide polymorphism associated with clopidogrel response: a whole-genome DNA methylation analysis in acute coronary syndrome.

Background: Dual antiplatelet therapy with clopidogrel and aspirin is the primary treatment for patients who undergo percutaneous coronary intervention. However, the interindividual difference in clopidogrel response is remarkable, and high on-treatment platelet reactivity (HTPR) can increase the risk of thrombotic events after percutaneous coronary intervention.

Objective: We studied novel accessible factors that possibly affect clopidogrel response in DNA methylation.

Pharmacogenomics in drug-induced cardiotoxicity: Current status and the future.

Drug-induced cardiotoxicity (DICT) is an important concern of drug safety in both drug development and clinical application. The clinical manifestations of DICT include cardiomyopathy, arrhythmia, myocardial ischemia, heart failure, and a series of cardiac structural and functional changes. The occurrence of DICT has negative impacts on the life quality of the patients, brings additional social and economic burden.

Methyltransferase-like 3 promotes the progression of lung cancer via activating PI3K/AKT/mTOR pathway.

Methyltransferase-like 3 (METTL3) catalyses N6-methyladenosine (m A) modification on messenger RNA (mRNA) and participates in a wide range of biological functions via epigenetically regulating gene expression. Recent studies suggested that dysregulation of METTL3 is associated with multiple human cancers; however, the role of METTL3 in lung cancer remains unclear. In the present study, through transcriptome analysis of lung cancer patients, we found that METTL3 is overexpressed in lung cancer patients and is associated with poor patient survival.

Possible causes of atherosclerosis: lncRNA induces oxidative stress in human coronary artery endothelial cells and impairs wound healing.

Background: Atherosclerosis is the most common cause of cardiovascular disease, accompanied by high mortality and poor prognosis. Low-density lipoprotein (LDL) and its oxidized form oxidized low-density lipoprotein (oxLDL) play an important role in atherosclerosis. This article will explore the role of the lncRNA (colorectal cancer associated 1)// (secreted phosphoprotein 1) pathway in oxLDL in causing human coronary artery endothelial cells (HCAECs) inflammation and related biological function changes.

Phenanthroline-imine ligands for iron-catalyzed alkene hydrosilylation.

Iron-catalyzed organic reactions have been attracting increasing research interest but still have serious limitations on activity, selectivity, functional group tolerance, and stability relative to those of precious metal catalysts. Progress in this area will require two key developments: new ligands that can impart new reactivity to iron catalysts and elucidation of the mechanisms of iron catalysis. Herein, we report the development of novel 2-imino-9-aryl-1,10-phenanthrolinyl iron complexes that catalyze both -Markovnikov hydrosilylation of terminal alkenes and 1,2--Markovnikov hydrosilylation of various conjugated dienes.

Association of FMO3 rs1736557 polymorphism with clopidogrel response in Chinese patients with coronary artery disease.

Purpose: Dual antiplatelet therapy with aspirin and clopidogrel is commonly used for coronary artery disease (CAD) patients undergoing percutaneous coronary intervention to prevent stent thrombosis and ischemic events. However, some patients show high on-treatment platelet reactivity (HTPR) during clopidogrel therapy. Genetic factors such as loss-of-function variants of CYP2C19 are validated to increase the risk of HTPR.

Effects of Amorphous and Nanocrystalline Structures on Hydrogen-Induced Optical Performance of Modulated Mg-Gd Films with Various Composition Fluctuations.

Nanomodification and amorphization are vital for improving the hydrogenation properties of magnesium (Mg)-based alloys. However, comparisons of their positive effects have been rarely presented because their usual fabrication process of annealing is hard to control. In this study, after tuning the composition fluctuation range, self-assembled well-ordered multilayer MgGd films with an excessive amount of nanosized crystals were fabricated by deviating substrates to the edge of the sample stage, while relatively low crystallinity was gained at the center of the sample stage with a small composition fluctuation.

Double C-N bond cleavages of N-alkyl 4-oxopiperidinium salts: access to unsymmetrical tertiary sulfonamides.

In this paper, regiospecific, double intraannular C-N bond cleavages of N-alkyl 4-oxopiperidinium salts are presented. The reaction sequence involves a charge-transfer complex, in situ formed between sulfonyl chloride and N-methylmorpholine, which induces S-Cl bond homolysis of sulfonyl chloride, yielding a reactive sulfonyl radical that further induces the double C-N bond cleavages of N-alkyl 4-oxopiperidinium salt. The secondary amine thus produced was trapped by sulfonyl chloride to yield the desired sulfonamide product.
