The GPR4 antagonist NE 52-QQ57 prevents ox-LDL-induced cellular senescence by promoting the expression of SIRT1.

Background: Cell senescence-associated endothelia dysfunction is a vital point in the pathological progression of atherosclerosis (AS). G-protein coupled receptor 4 (GPR4) is a proton-sensing receptor involved in developing endothelial dysfunction.

Objective: In this study, we investigated the protective role of NE 52-QQ57, a GPR4 inhibitor in endothelial cell senescence induced using an oxidized low-density lipoprotein (ox-LDL).

Characterization and Health Risk Assessment of Airborne Fungi in a Semiunderground Municipal Wastewater Treatment Plant.

Municipal wastewater treatment plants (WWTPs) are recognized as the significant source of fungal aerosols, which pose a significant threat to human health globally. Herein, the occurrences characterization, community structure, and health risk assessment of airborne fungi were investigated from a semiunderground WWTP. The concentrations of culturable fungi emitted into the air from the WWTP ranged from 30.

The addition of alpha-ketoglutarate to NT-proBNP improves the prediction of long-term all-cause mortality in acute heart failure patients.

Background And Objective: Alpha-ketoglutarate (AKG), is a major intermediate metabolite of the tricarboxylic acid cycle, and is closely associated with cardiometabolic disease prognosis. Previous studies indicated that AKG is related to myocardial energy expenditure levels and reflects adverse short-term outcomes in heart failure (HF) patients. In this prospective cohort study, we examined the long-term prognostic value of AKG levels in acute HF (AHF) patients.

Anti-atherosclerotic effect of incretin receptor agonists.

Incretin receptor agonists (IRAs), primarily composed of glucagon-like peptide-1 receptor agonists (GLP-1RAs) and glucose-dependent insulinotropic polypeptide receptor agonists (GIPRAs), work by mimicking the actions of the endogenous incretin hormones in the body. GLP-1RAs have been approved for use as monotherapy and in combination with GIPRAs for the management of type 2 diabetes mellitus (T2DM). In addition to their role in glucose regulation, IRAs have demonstrated various benefits such as cardiovascular protection, obesity management, and regulation of bone turnover.

Culturable and inhalable airborne bacteria in a semiunderground municipal wastewater treatment plant: Distribution, transmission, and health risk assessment.

Airborne pathogens constitute a growing threat to global public health. Wastewater treatment plants (WWTPs) are important sources of airborne bacteria, which pose great health risks to the employee and nearby residents. In this study, the distribution, transmission and health risk of the airborne culturable and inhalable bacteria carried by PM in a semiunderground WWTP were evaluated.

ox-LDL induces autophagy-mediated apoptosis by suppressing secretagogin-regulated autophagic flux in pancreatic β-cells.

Lipotoxicity has been shown to induce the loss of functional β-cell mass and lead to type 2 diabetes, but the mechanism remains unknown. In this study, we aim to explore the role of secretagogin (SCGN) in lipotoxicity-induced β-cell injury. Our results indicate that ox-LDL treatment leads to autophagic cell death, as evidenced by decreased cell viability, aggravated cell apoptosis, and the accumulation of the p62 protein in MIN6 cells.

CTRP15 promotes macrophage cholesterol efflux and attenuates atherosclerosis by increasing the expression of ABCA1.

C1q tumor necrosis factor-related protein 15 (CTRP15), a newly identified myokine, is closely implicated in cardiovascular disease. However, the role of CTRP15 in atherosclerosis is still unclear. This study aims to determine the role of CTRP15 in atherosclerosis and explore the underlying mechanisms.

Therapeutic effect of SP-8356 on pulmonary embolism-associated cardiac injury is mediated by its ability to suppress apoptosis and inflammation.

The cyclophilin A-CD147 interaction has been reported to be one of the most potential therapeutic targets for the treatment of acute pulmonary embolism. The signalling of extracellular signal-regulated kinase 1/2 (ERK1/2) was also reported in the pathogenesis of cardiac injury. Since SP-8356 is regarded as a novel Inhibitor of CD147-Cyclophilin, the study aimed to evaluate potential therapeutic effects of SP-8356 for pulmonary embolism-associated cardiac injury.

Trelagliptin Alleviates Lipopolysaccharide (LPS)-Induced Inflammation and Oxidative Stress in Acute Lung Injury Mice.

Acute lung injury (ALI) is an urgent disease lacking effective therapies, resulting in relatively high morbidity and mortality. The pathological mechanism of ALI is reported to be related to excessive inflammation and activated oxidative stress. The present study aims to investigate the protective effects of the DPP-4 inhibitor Trelagliptin against lipopolysaccharide (LPS)-induced ALI and the underlying mechanism.

LncRNA NEAT1 promotes apoptosis and inflammation in LPS-induced sepsis models by targeting miR-590-3p.

Sepsis is a complication of infection caused by disease or trauma. Increasing evidence have shown that long noncoding RNAs (lncRNAs) are involved in the regulation of sepsis. However, the mechanism of lncRNA nuclear enriched abundant transcript 1 (NEAT1) in the regulation of sepsis progression remains to be elucidated.

One-year change in resting heart rate and subsequent risk of hypertension in healthy Chinese adults.

Background: Changes in baseline resting heart rate (RHR) appear to predict new-onset hypertension (NOH). However, RHR is a dynamic anthropometric parameter; thus, the association between changes in RHR and NOH requires further investigation.

Methods: We studied 10 403 participants who were initially normotensive and who had at least one routine health examination at baseline and 1 year later during 2011-2016.

Association of Urine Albumin/Creatinine Ratio below 30 mg/g and Left Ventricular Hypertrophy in Patients with Type 2 Diabetes.

Several studies show that even a level of urine albumin/creatinine ratio (UACR) within the normal range (below 30 mg/g) increases the risk of cardiovascular diseases. We speculate that mildly increased UACR is related to left ventricular hypertrophy (LVH) in patients with type 2 diabetes mellitus (T2DM). In this retrospective study, 317 patients with diabetes with normal UACR, of whom 62 had LVH, were included.

Association between admission plasma 2-oxoglutarate levels and short-term outcomes in patients with acute heart failure: a prospective cohort study.

Background: 2-oxoglutarate (2OG), an intermediate metabolite in the tricarboxylic acid cycle, has been found to associate with chronic heart failure (HF), but its effect on short-term adverse outcomes in patients with acute HF (AHF) is uncertain.

Methods: This prospective cohort study included 411 consecutive hospitalized patients with AHF. During hospitalization, fasting plasma samples were collected within the first 24 h of admission.

Association between early serum cholinesterase activity and 30-day mortality in sepsis-3 patients: A retrospective cohort study.

Low serum cholinesterase (SCHE) activity has been associated with poor prognoses in a variety of conditions, including sepsis. However, such an association has not been well characterized since the Third International Consensus Definitions Task Force modified the definition of sepsis to "life-threatening organ dysfunction due to a dysregulated host response to infection" (known as sepsis-3) in 2016. In the current retrospective cohort study, we examined whether 30-day mortality in sepsis-3 patients is associated with SCHE activity.
