Role of plasma neuropeptide Y in acute myocardial infarction: a case-control study.

Background: As neuropeptide Y is associated with endothelial dysfunction, this study explored the relationship between neuropeptide Y and acute myocardial infarction.

Methods: We included 128 acute myocardial infarction cases and 62 controls. Using the SYNTAX scoring system, the acute myocardial infarction group was sub-grouped into "SYNTAX ≤ 22," "SYNTAX = 23-32," and "SYNTAX ≥ 33.

A novel radiomics-based technique for identifying vulnerable coronary plaques: a follow-up study.

Background: Previous reports have suggested that coronary computed tomography angiography (CCTA)-based radiomics analysis is a potentially helpful tool for assessing vulnerable plaques. We aimed to investigate whether coronary radiomic analysis of CCTA images could identify vulnerable plaques in patients with stable angina pectoris.

Methods: This retrospective study included patients initially diagnosed with stable angina pectoris.

Stem cell-derived exosomes in the treatment of acute myocardial infarction in preclinical animal models: a meta-analysis of randomized controlled trials.

Background: Exosomes (EXOs) derived from stem cells have become a potential new treatment for acute myocardial infarction (AMI). However, their impact is still not fully understood. Therefore, we performed this meta-analysis to systematically review the efficacy of EXOs on AMI in preclinical animal models.

Determination of trace fluoride in water samples by silylation and gas chromatography/mass spectrometry analysis.

Rationale: Due to the ubiquity of fluorides and the small gap between a safe dose and a harmful one, it is necessary to develop a robust analytical method for determination of fluoride ions in various water samples with complex matrices.

Methods: Silylation of the fluoride ion was carried out by treatment with hydrochloric acid and phenyldimethylchlorosilane at room temperature. The formed phenyldimethylfluorosilane was detected by gas chromatography/mass spectrometry (GC/MS).

The role of Wnt signaling pathway in atherosclerosis and its relationship with angiogenesis.

Expression and function of Wnt signaling pathway in rats with atherosclerosis (AS) were investegated. The AS model of rats was established after 8-week continuous feeding of a high-fat diet, with normal rats as the control. Blood was taken from the carotid artery to detect the level of blood lipid.

Effect of influent COD/SO4(2-) ratios on UASB treatment of a synthetic sulfate-containing wastewater.

The effect of the chemical oxygen demand/sulfate (COD/SO4(2-)) ratio on the anaerobic treatment of synthetic chemical wastewater containing acetate, ethanol, and sulfate, was investigated using a UASB reactor. The experimental results show that at a COD/SO4(2-) ratio of 20 and a COD loading rate of 25.2gCODL(-1)d(-1), a COD removal of as high as 87.

Effect of viscosity on the mixing efficiency in a self-agitation anaerobic baffled reactor.

One special self-agitation reactor, which does not require a mechanical mixer or other equipment for mixing, has been introduced. Self-agitation is affected by variation in viscosity property. To obtain and research the effect of viscosity on mixing behavior in the self-agitation reactor, Fluent® was used to create numerical simulations and to visualize the fluid flow status.

Influence of four antimicrobials on methane-producing archaea and sulfate-reducing bacteria in anaerobic granular sludge.

The influence of Cephalexin (CLX), Tetracycline (TC), Erythromycin (ERY) and Sulfathiazole (ST) on methane-producing archaea (MPA) and sulfate-reducing bacteria (SRB) in anaerobic sludge was investigated using acetate or ethanol as substrate. With antimicrobial concentrations below 400mgL(-1), the relative specific methanogenic activity (SMA) was above 50%, so that the antimicrobials exerted slight effects on archaea. However ERY and ST at 400mgL(-1) caused a 74.

Characterization of controlled low-strength material obtained from dewatered sludge and refuse incineration bottom ash: mechanical and microstructural perspectives.

Potential reuse of dewatered sludge (DS) and municipal solid waste incineration (MSWI) bottom ash as components to develop controlled low-strength material (CLSM) was explored. The effects of DS:MSWI bottom ash:calcium sulfoaluminate (CS¯A) cement ratio and thermal treatment of MSWI bottom ash at 900 °C on the mechanical and microstructural properties of CLSM were intensively studied to optimize the process. Results showed DS and MSWI bottom ash could be utilized for making CLSM.

[Sodium hypochlorite disinfection on effluent of MBR in municipal wastewater treatment process].

Sodium hypochlorite (NaClO) used in wastewater disinfection was assessed by examining its performances in lab fed by the effluent from a MBR treatment plant. The influence of sodium hypochlorite initial concentrations (0.5-3.
