Lead‐free Na 0.5 K NbO 3 (NKN) piezoelectric ceramics were fairly well densified at a relatively low temperature under atmospheric conditions. A relative density of 96%–99% can be achieved by either using high‐energy attrition milling or adding 1 mol% oxide additives. It is suggested that ultra‐fine starting powders active oxygen vacancies and even liquid phases from B‐site additives mainly lead to improved sintering. Not only dielectric properties influenced additives, such as the Curie ( T...
Abstract Hypertension is proved to be associated with severity and mortality in coronavirus disease 2019 (COVID‐19). However, little known about the effects of pre‐admission and/or in‐hospital antihypertension treatments on clinical outcomes. Thus, this study aimed investigate association between blood pressure (BP) control COVID‐19–related outcomes compare different treatments. This included 2864 COVID‐19 patients 1628 were hypertensive. Patients grouped according their BP during...
Abstract Statins play a major role in reducing circulating cholesterol levels and are widely used to prevent coronary artery disease. Although they recently confirmed up-regulate mitophagy, little is known about the molecular mechanisms its effect on endothelial progenitor cell (EPC). Here, we explore mechanism underlying statin (pitavastatin, PTV)-activated mitophagy EPC proliferation. ApoE −/− mice fed high-fat diet for 8 weeks induce atherosclerosis. In these mice, proliferation decreases...
Hypobaric hypoxia (HH) is the primary challenge at highland. Prolonged HH exposure impairs right cardiac function. Mitochondria-associated membrane (MAM) plays a principal role in regulating mitochondrial function under hypoxia, but mechanism was unclear. In this study, proteomics analysis identified that PACS2, key protein MAM, and mitophagy were downregulated HH. Metabolomics indicated suppression of glucose fatty acids aerobic oxidation conditions. Cardiomyocyte Pacs2 deficiency disrupted...
Bisphenol A (BPA), an environmental pollutant, has received considerable attention worldwide for its hazardous effects of promoting atherosclerosis and increasing the risk cardiovascular diseases (CVDs). However, mechanisms involved are unclear. We aimed to investigate underlying BPA-aggravated potential preventive treatments. Four-week-old male Ldlr-/- C57BL/6 mice were administered 250 μg/L BPA via drinking water 30 weeks with or without a Western diet and/or resveratrol (RESV) 12 weeks....
Male novel coronavirus disease (COVID-19) patients tend to have poorer clinical outcomes than female patients, while the myocardial injury is strongly associated with COVID-19-related adverse events. Owing a lack of corresponding data, we aimed investigate sex differences in incidence COVID-19 and identify potential underlying mechanisms, which may partly account for bias This retrospective study included 1,157 who were hospitalized Huoshenshan Hospital from 12 March 2020 11 April 2020. Data...
Abstract Extreme cold exposure has been widely considered as a cardiac stress and may result in function decompensation. This study was to examine the risk factors that contribute changes cardiovascular indicators of following extreme provide valuable insights into preservation adaptation occur real‐world environment. Seventy subjects were exposed outside (Mohe, mean temperature −17 −34°C) for one day, monitored by 24‐h ambulatory blood pressure device underwent echocardiography examination...
Different amounts of silver (0.5–10 wt%) have been mixed with EIA X7R‐type ceramic powders based on barium titanate. The XRD analysis indicated that no phases other than BaTiO 3 and were present in the doped ceramics; it further suggested reaction took place between during calcination sintering. SEM observation showed particles presented island distribution matrix. densification dielectric properties silver‐doped ceramics disk form investigated. A large amount addition (>1 was found to...
To analyze the CT imaging results of patients with COVID-19 who previously received several follow-up visits and to explain changes in pulmonary inflammation.Cases 15 were retrospectively analyzed: their epidemiology, clinical history, laboratory tests, multiple chest scans obtained during disease period studied.The showed different results. Four had no abnormal findings scans. The first scan 1 patient revealed right lower lobe inflammation, while lesion been completely absorbed follow-up....
Hypertension is the most common comorbidity in patients with coronavirus disease 2019 (COVID-19) and increases in-hospital mortality. Day-by-day blood pressure (BP) variability (BPV) associated clinical outcomes hypertensive patients. However, little information available on association of BPV COVID-19 hypertension. This study aimed to demonstrate whether day-by-day had prognostic significance these The authors included 702 hypertension from Huoshenshan Hospital (Wuhan, China), who underwent...
A modified Campbell model has been provided considering the internal stress and “core‐shell” microstructure that occurs in X7R‐type multilayer ceramic capacitors (MLCCs). The capacitance stability coefficient α was defined to denote effect of a direct current (DC) bias field on MLCCs. According this model, dielectric constant will decrease with DC while increase. properties MLCCs different active layers, sintering temperatures, grain size, strontium doping concentration were measured order...
Textured bismuth titanate ceramics were successfully produced using spark plasma sintering and platelike particles prepared a molten‐salt method. The microstructure dielectric properties of the samples investigated. results showed that property textured was anisotropic in various directions an effective technology to obtain textured, dense at low temperature.
Background Patients with atrial fibrillation (AF) who undergo radiofrequency catheter ablation (RFCA) necessitate the administration of antiarrhythmic drugs to prevent early recurrence. The clinical outcomes among these patients may be influenced by varying regimens. Objectives To identify risk factors associated recurrence and compare different regimens in elderly AF following during a 3-month period. Methods A retrospective observational study encompassed 420 RFCA. Baseline data were...
Background: Acute high-altitude (HA) exposure results in blood pressure (BP) and cardiac function variations most subjects, some of whom suffer from acute mountain sickness (AMS). Several previous studies have found that cardiovascular indicators are potentially correlated with AMS. Objectives: This study aims to examine HA-induced adaptations AMS patients compare them healthy subjects. It also investigate the relationship between AMS, as well provide insightful information about prevention...
Atrial fibrillation (AF) is associated with an increased risk of thrombosis the left atrial appendage (LAA). However, molecular mechanisms underlying this site-specificity remain poorly understood. Here, we present a comparative single-cell transcriptional profile paired appendages from patients AF and illustrate chamber-specific properties main cell types.Single-cell RNA sequencing analysis matched samples three persistent was evaluated by 10× genomics. The mice model created using Tbx5...
