Effect of ultrasound treatment on antioxidant activity and structure of β-Lactoglobulin were investigated using antioxidant indexes and spectroscopy techniques. The 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities had been applied to the experimental response obtained by a three-factor-three-level Box–Behnken design. Results showed that ultrasound treatment significantly increased antioxidant activity (p

Introduction and Objectives: Coronary microvascular dysfunction (CMD) is highly prevalent and is recognized as an important clinical entity in patients with coronary heart disease (CHD). Nevertheless, the association of CMD with adverse cardiovascular events in the spectrum of CHD has not been systemically quantified., Methods: We searched electronic databases for studies on patients with CHD in whom coronary microvascular function was measured invasively, and clinical events were recorded. The primary endpoint was major adverse cardiac events (MACE), and the secondary endpoint was all-cause death. Estimates of effect were calculated using a random-effects model from published risk ratios., Results: We included 27 studies with 11 404 patients. Patients with CMD assessed by invasive methods had a higher risk of MACE (RR, 2.18; 95%CI, 1.80-2.64; P<.01) and all-cause death (RR, 1.88; 95%CI, 1.55-2.27; P<.01) than those without CMD. There was no significant difference in the impact of CMD on MACE (interaction P value=.95) among different invasive measurement modalities. The magnitude of risk of CMD assessed by invasive measurements for MACE was greater in acute coronary syndrome patients (RR, 2.84, 95%CI, 2.26-3.57; P<.01) than in chronic coronary syndrome patients (RR, 1.77, 95%CI, 1.44-2.18; P<.01) (interaction P value<.01)., Conclusions: CMD based on invasive measurements was associated with a high incidence of MACE and all-cause death in patients with CHD. The magnitude of risk for cardiovascular events in CMD as assessed by invasive measurements was similar among different methods but varied among CHD populations., (Copyright © 2024 Sociedad Española de Cardiología.

Introduction: This study aimed to explore the diagnostic value and the correlation of the combined detection of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) with sepsis-induced cardiomyopathy (SIC)., Patients and Methods: Admitted to our hospital from January 2017 to January 2019, 96 patients with SIC (a study group) and 90 patients with sepsis (a control group) were enrolled. The three cytokines were determined and the diagnostic value of their combined detection for SIC was analyzed., Results: The cytokines were remarkably higher in the study group (p<.001). The combined detection of the three had a better diagnostic value for SIC (p<.001). The three cytokines were independent risk factors for the death of patients with SIC., Conclusion: IL-1β, IL-6, and TNF-α in SIC patients rise markedly. The combined detection of the three has a better predictive value for patients with SIC and is closely related to the patients' prognoses, so it may be crucial in diagnosing and treating the disease., Competing Interests: Conflict of interest None., (Copyright © 2021 Elsevier España, S.L.U.
