Effects of Heart Rate Fluctuation on Aerobic Training Outcomes in Patients With Stable Coronary Artery Disease: A Prospective Study.

Background: This study aimed to evaluate the effects of different heart rate fluctuation ranges during aerobic training on outcomes in patients with stable coronary artery disease (CAD).

Methods: Ninety-seven patients diagnosed with stable CAD were enrolled between March 2017 and December 2019. Participants were randomly assigned to three groups: the control (CON) group, the medium-intensity heart rate small range (MIS) group, and the medium-intensity heart rate large range (MIL) group.

Surface Modification with CuFeS Nanocrystals to Improve the Efficiency and Stability of Perovskite Solar Cells.

Poor stability retards the industrialization of perovskite solar cells (PSCs). One of the effective ways to solve this issue is to modify the perovskite surface to improve the efficiency and stability of the PSCs. Herein, we synthesized CuFeS nanocrystals and applied them to modify the perovskite surface.

[Optimization and Validation of the Analytical Method to Detect Common Illicit Drugs in Wastewater].

Illicit drugs have been recognized as a group of emerging pollutants.Based on previous research,procedures to pre-treat wastewater including SPE column,pH of water samples,and processes of washing,acidifying and re-dissolving were compared.It was found that the best recovery was achieved when wastewater was adjusted to pH=2 and Oasis MCX column was used.

[Concentrations of Ketamine and Norketamine in the Water Environment in Beijing].

Concentrations of ketamine (KET) and its metabolite, norketamine (NK) in sewage water and surface water in Beijing were examined by HPLC-MS/MS. Samples were collected from all the thirteen sewage treatment plants in the urban area and four rivers flowing through the city. Average influent concentrations of KET and NK in 2013 summer ranged from View Article and Find Full Text PDF

aqueous extract and its active constituent quercetin potentiate the hypnotic effect of pentobarbital via the serotonergic system.

(FA) is reportedly used for treatment of insomnia and anxiety in traditional medicine. The hypnotic effect of an extract of FA (FAE) and its constituent quercetin [2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-4H-chromen-4-one, QR] was examined in mice. QR is a widely distributed natural flavonoid abundant in FA flowers and other tissues.

[Study on extraction process of polysaccharide from Sargassum fusiforme by enzymatic treatment].

Objective: To investigate the optimal extraction process of polysaccharides from S. fusiforme by enzymatic treatment.

Method: The optimum extraction conditions were obtained by the experiment with the orthogonal design.

[Study on the apoptosis of HL-60 human promyeloid leukaemia cells induced by SFPS].

The inhibition effects of Sargassum fusiforme Polysaccharides (SFPS) on proliferation of human HL-60 promyeloid leukemia cells were measured by MTT assay. SFPS-induced apoptosis in HL-60 cells was observed by electron microscopy, flow cytometry and DNA electrophoresis. The results revealed that SFPS exhibited antiproliferative activity which depended on dosage and time.
