Risk stratification by stress echocardiography: a whiter shade of pale? [PDF]

European Journal of Echocardiography, 2004
Please see page 205 for the article by Moreno et al. (doi: 10.1016/j.euje.2003.11.008) to which this editorial pertains. In this issue of the Journal, Moreno et al. show the high negative predictive value of a negative dipyridamole stress echocardiogram in medically stabilized unstable angina.1 The negative predictive value was, however, lower in ...

Effect of simultaneous shade and drought stress on morphology, leaf gas exchange, and yield parameters of different soybean cultivars

Photosynthetica, 2020
An interactive effect of simultaneous shade and drought stress on drought-tolerant and drought-sensitive cultivars of soybean was studied. As drought stress intensified, the net photosynthetic rate decreased in both cultivars due to reduced leaf area ...

Benefit of shading by nurse plant does not change along a stress gradient in a coastal dune. [PDF]

PLoS ONE, 2014
The proximity of adult neighbors often increases the performance of woody seedlings under harsh environmental conditions but this nurse plant effect becomes less intense when abiotic stress is alleviated, as predicted by the stress gradient hypothesis ...

Seedling growth and photosynthetic response of Pterocarpus indicus L. to shading stress

Plant Signaling & Behavior, 2023
In tropical forests, the shade provided by tree canopies and extreme climate causes inhibition of plant seedling growth due to the lack of light. However, the plants can acclimate to such environmental stress by generating specific responses. The present study aimed to investigate the effects of shading conditions on ecophysiological performance of ...

Heat Stress Interaction with Shade and Cooling

Journal of Dairy Science, 1994
Hot weather causes heat stress in dairy cattle. Although effects are more severe in hot climates, dairy cattle in areas with relatively moderate climates also are exposed to periods of heat stress. The resultant decrease in milk production and reproductive efficiency can be offset by implementation of a program consisting of cooling through shades ...

Effects of shading on morphology, photosynthesis characteristics, and yield of different shade-tolerant peanut varieties at the flowering stage

Frontiers in Plant Science
IntroductionIn maize and peanut intercropping, shading emerges as a critical factor for restricting peanut growth, yield, and quality.MethodsThis study investigated the impact of 30% shade on shade-tolerant [Huayu 22 (HY22) and Fuhua 12 (FH12)] and shade-

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Shades of Stress: Colorism as Minority Stress for Women of Color

Psychology of Women Quarterly
Women of color often endure indignities shaped by colorism and skin tone discrimination, pressuring them to adhere to racialized beauty ideals (i.e., lighter skin). In response, some women of color may internalize these standards (i.e., through internalized coping and racial self-hatred) which can foster psychological distress.
