Effects of IL-38 on Macrophages and Myocardial Ischemic Injury.

Macrophages play an important role in clearing necrotic myocardial tissues, myocardial ischemia-reperfusion injury, and ventricular remodeling after myocardial infarction. M1 macrophages not only participate in the inflammatory response in myocardial tissues after infarction, which causes heart damage, but also exert a protective effect on the heart during ischemia. In contrast, M2 macrophages exhibit anti-inflammatory and tissue repair properties by inducing the production of high levels of anti-inflammatory cytokines and fibro-progenitor cells.

Laser solid-phase synthesis of single-atom catalysts.

Single-atom catalysts (SACs) with atomically dispersed catalytic sites have shown outstanding catalytic performance in a variety of reactions. However, the development of facile and high-yield techniques for the fabrication of SACs remains challenging. In this paper, we report a laser-induced solid-phase strategy for the synthesis of Pt SACs on graphene support.

GARP and GARP-Treated tDC Prevented the Formation of Atherosclerotic Plaques in ApoE Mice.

Purpose: This study aims to clarify the specific mechanism by which GARP affects the atherosclerotic plaques in ApoE mice and the effect of GARP-tDC on atherosclerosis.

Methods: The mice were randomly divided into three groups: the control group, the GARP-overexpressed group and the GARP-inhibited group. After 12 weeks, all the mice were euthanized, and the specimens were collected.

Phosphorylcholine-Primed Dendritic Cells Aggravate the Development of Atherosclerosis in ApoE Mice.

Atherosclerosis is an inflammatory disease involving activation of adaptive and innate immune responses to antigens, including oxidized low-density lipoprotein (oxLDL) and phosphorylcholine (PC). Dendritic cells (DCs), which are antigen-presenting cells that activate T cells, are present in atherosclerotic lesions and are activated in immune organs. However, the mechanism by which PC promotes atherosclerosis is unclear.

Modulation of Charge Transport at Grain Boundaries in SrTiO: Toward a High Thermoelectric Power Factor at Room Temperature.

Modulation of the grain boundary properties in thermoelectric materials that have thermally activated electrical conductivity is crucial in order to achieve high performance at low temperatures. In this work, we show directly that the modulation of the potential barrier at the grain boundaries in perovskite SrTiO changes the low-temperature dependency of the bulk material's electrical conductivity. By sintering samples in a reducing environment of increasing strength, we produced LaSrTiO (LSTO) ceramics that gradually change their electrical conductivity behavior from thermally activated to single-crystal-like, with only minor variations in the Seebeck coefficient.

This study aimed to summarize the clinical characteristics and laboratory indicators of patients with COVID-19 with CVD, especially the critically ill patients.

Unravelling the Mechanism of Rechargeable Aqueous Zn-MnO Batteries: Implementation of Charging Process by Electrodeposition of MnO.

Poor cycling stability and mechanistic controversies have hindered the wider application of rechargeable aqueous Zn-MnO batteries. Herein, direct evidence was provided of the importance of Mn in this type of battery by using a bespoke cell. Without pre-addition of Mn , the cell exhibited an abnormal discharge-charge profile, meaning it functioned as a primary battery.

The Long Noncoding RNA Hotair Regulates Oxidative Stress and Cardiac Myocyte Apoptosis during Ischemia-Reperfusion Injury.

Oxidative stress and subsequent cardiac myocyte apoptosis play central roles in the initiation and progression of myocardial ischemia-reperfusion (I/R) injury. Homeobox transcript antisense intergenic RNA () was previously implicated in various heart diseases, yet its role in myocardial I/R injury has not been clearly demonstrated. Mice with cardiac-restricted knockdown or overexpression of were exposed to I/R surgery.

Knockdown of TRIM28 inhibits PDGF-BB-induced vascular smooth muscle cell proliferation and migration.

Atherosclerosis is a common type of cardiovascular disease (CVD), remaining one of the leading causes of global death. Tripartite motif-containing 28 (TRIM28) is a member of TRIM family that has been found to be involved in atherosclerosis. However, the role of TRIM28 in atherosclerosis remains unknown.

Decreased Helios Expression in Regulatory T Cells in Acute Coronary Syndrome.

Regulatory T cells (Tregs) play an essential role in acute coronary syndrome (ACS). However, there is debate about which Treg subsets are truly critical to ACS. Helios, a transcription factor, was recently reported to be a bona fide marker for natural Tregs or activated Tregs with a suppression function, but little is known about its role in ACS.

Thymic stromal lymphopoietin-induced HOTAIR activation promotes endothelial cell proliferation and migration in atherosclerosis.

Endothelial cells' (EC) injury is a major step for the pathological progression of atherosclerosis. Recent study demonstrated that thymic stromal lymphopoietin (TSLP) exerts a protective role in atherosclerosis. However, the effect of TSLP and the exact molecular mechanism involved in EC remains unknown.

Meta-analysis of serum non-high-density lipoprotein cholesterol and risk of coronary heart disease in the general population.

Background: Non-high-density lipoprotein cholesterol (non-HDL-C) has been proposed an independent risk factor for coronary heart disease (CHD). However, the magnitude of this association in the general population varied considerably.

Objective: To investigate the association of baseline non-HDL-C level with CHD risk in the general population by conducting a meta-analysis.

Cardioprotective Effects of Malvidin Against Isoproterenol-Induced Myocardial Infarction in Rats: A Mechanistic Study.

BACKGROUND Malvidin (alvidin-3-glucoside) is a polyphenol that belongs to the class of natural anthocyanin, which is abundantly found in red wines, colored fruits, and the skin of red grapes. Therefore, the current investigation was intended to evaluate the effect of malvidin against myocardial infarction induced by isoproterenol in the rats. MATERIAL AND METHODS The cardioprotective effects was assessed by determining the effect of malvidin on the activities of endogenous antioxidants - catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH) - and on the levels of lipid peroxidation and serum marker enzymes.

Abnormal expression of thymic stromal lymphopoietin (TSLP) and its receptor (TSLPR) was found in patients with acute coronary syndrome. Ticagrelor, an oral platelet ADP P2Y12 receptor antagonist, is widely used in these patients. The aim of this study was to verify whether different doses of ticagrelor regulated plaque progression and platelet activity by modulating TSLP/TSLPR.

Heme oxygenase-1 restores impaired GARPCD4⁺CD25⁺ regulatory T cells from patients with acute coronary syndrome by upregulating LAP and GARP expression on activated T lymphocytes.

Background: Accumulating evidence shows that the pathological autoreactive immune response is responsible for plaque rupture and the subsequent onset of acute coronary syndrome (ACS). Naturally occurring CD4(+)CD25(+)regulatory T cells (nTregs) are indispensable in suppressing the pathological autoreactive immune response and maintaining immune homeostasis. However, the number and the suppressive function of glycoprotein-A repetitions predominant (GARP) (+) CD4(+) CD25(+) activated nTregs were impaired in patients with ACS.
