Abstract
Abstract
Background
The optimal management of asymptomatic aortic stenosis (AS) remains controversial. The aim of this study is to investigate the prognostic value of exercise stress echocardiography (ESE) in asymptomatic patients with AS.
Purpose
To investigate the additive value of ESE in asymptomatic patients with AS.
Methods and results
We retrospectively enrolled 109 consecutive patients (mean age 73±13 years, 55 men) with AS (aortic valve area ≤1.5cm2) who underwent ESE. Of these, 10 patients referred for aortic valve replacement without symptoms were excluded; finally, 99 conservatively managed patients were enrolled. During the mean follow-up period of 14±11 months, 23 patients (23%) suffered from AS related events. Although no differences in mean pressure gradient at rest and during exercise were found between the patients with and without adverse events, transvalvular flow rate during exercise (Ex-FR) was lower in patients with adverse events than those without adverse events (236±55 ml/sec vs 274±64 ml/sec, P=0.01). Using multivariate Cox regression analysis, low Ex-FR (<270 ml/sec) was an independent predictor for adverse events in patients with asymptomatic AS (hazard ratio: 3.53, P<0.01). The Kaplan–Meier analysis showed that Ex-FR was clearly stratified the event-free survival (Figure, log-rank P<0.01).
K-M curve according to Ex-FR
Conclusion
These results suggested that Ex-FR measured by ESE should play crucial roles in risk stratification in asymptomatic patients with AS.

Abstract
Abstract
Background
Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition that may present crucial complication including life-threatening arrhythmia and sudden cardiac death. However, the risk stratification of HCM without left ventricular outflow tract (LVOT) obstruction had not been fully elucidated. Moreover, although recent studies have revealed the right ventricle (RV) involvement of HCM, the prognostic importance of RV function during exercise is unclear.
Purpose
To investigate the prognostic significance of RV function in patients with non-obstructive HCM using exercise stress echocardiography (ESE).
Methods and results
This study conducted on 100 HCM patients (age 62.9±13.6 years, 63% men) with preserved left ventricular ejection fraction who underwent ESE using semi-supine bicycle ergometer. Ten patients with significant LVOT obstruction (≥30mmHg) were excluded and 9 were also excluded because of the inadequate imaging quality or insufficiency of data. Among remaining 81 non-obstructive HCM patients, 9 patients suffered from HCM related cardiac events including cardiac death, unexpected hospitalization, life-threatening arrhythmias, and new-onset of syncope during the mean follow up period of 2.6±1.6 years. A multivariate Cox Hazard analysis revealed that low tricuspid annular plane systolic excursion during exercise (Ex-TAPSE, cut-off: 24mm) was an independent predictor of cardiac events. (hazard ratio: 18.66, 95% confidence interval: 3.66–338.46, P<0.001) The estimated cumulative cardiac event free survival using the Kaplan-Meier method was significantly lower in patients with reduced Ex-TAPSE (<24mm) than those with preserved Ex-TAPSE (Log-rank, P<0.01).
K-M curve according to Ex-TAPSE
Conclusion
Ex-TAPSE had a strong predictive value of clinical outcomes in non-obstructive HCM patients. Right ventricular function during exercise may have crucial role in the risk stratification of non-obstructive HCM.

Abstract
High-temperature operation of semiconductor devices is widely demanded for switching/sensing purposes in automobiles, plants, and aerospace applications. As alternatives to conventional Si-based Schottky diodes usable only at 200°C or less, Schottky interfaces based on wide-bandgap semiconductors have been extensively studied to realize a large Schottky barrier height that makes high-temperature operation possible. Here, we report a unique crystalline Schottky interface composed of a wide-gap semiconductor β-Ga2O3 and a layered metal PdCoO2. At the thermally stable all-oxide interface, the polar layered structure of PdCoO2 generates electric dipoles, realizing a large Schottky barrier height of ~1.8 eV, well beyond the 0.7 eV expected from the basal Schottky-Mott relation. Because of the naturally formed homogeneous electric dipoles, this junction achieved current rectification with a large on/off ratio approaching 108 even at a high temperature of 350°C. The exceptional performance of the PdCoO2/β-Ga2O3 Schottky diodes makes power/sensing devices possible for extreme environments.

Abstract
Lysosomes have a central role in cellular catabolism, trafficking, and processing of foreign particles. Accumulation of endogenous and exogenous materials in lysosomes represents a common finding in nonclinical toxicity studies. Histologically, these accumulations often lack distinctive features indicative of lysosomal or cellular dysfunction, making it difficult to consistently interpret and assign adverse dose levels. To help address this issue, the European Society of Toxicologic Pathology organized a workshop where representative types of lysosomal accumulation induced by pharmaceuticals and environmental chemicals were presented and discussed. The expert working group agreed that the diversity of lysosomal accumulations requires a case-by-case weight-of-evidence approach and outlined several factors to consider in the adversity assessment, including location and type of cell affected, lysosomal contents, severity of the accumulation, and related pathological effects as evidence of cellular or organ dysfunction. Lysosomal accumulations associated with cytotoxicity, inflammation, or fibrosis were generally considered to be adverse, while those found in isolation (without morphologic or functional consequences) were not. Workshop examples highlighted the importance of thoroughly characterizing the biological context of lysosomal effects, including mechanistic data and functional in vitro readouts if available. The information provided here should facilitate greater consistency and transparency in the interpretation of lysosomal effects.
