Reflection Rumination Reduces Negative Emotional Processing During Goal-Directed Behavior: An ERP Study.

Trait rumination is a repetitive and often maladaptive attentional focus on the consequences of depression. Rumination independently contributes to cognitive control dysfunction associated with depression. However, it is not clear how the effects of rumination on cognitive control may contribute to negative attention biases as well, or whether it is specific to brooding or reflective rumination.

Traits and functions of alpine plant communities respond strongly but not always sufficiently to in situ climate change.

Increasing climate warming and summer droughts are known to affect mountain plant communities, their functional traits and life strategies. However, little is known about how strongly and efficiently communities respond to climate change, and how tightly plant responses are linked to responses of ecosystem functions. To test this, we transplanted alpine plant communities to subalpine conditions, exposing them to warming and drying.

Comparison, Agreement, and Significance Cutoffs of F-Flurpiridaz PET Myocardial Blood Flow Quantitation Methods and Software Packages.

F-flurpiridaz is a novel PET myocardial perfusion radiotracer with a high myocardial extraction fraction and low positron range, providing high-resolution images. Additionally, the linear relationship between F-flurpiridaz myocardial extraction and myocardial blood flow (MBF) over a wide range of flow values permits accurate MBF measurement. Several groups have developed strategies to quantitate F-flurpiridaz MBF with methodologic differences.

Comparison of horizontal and traditional block family medicine curricula: Canadian study.

Objective: Longitudinal curriculum model outcomes in postgraduate medical education are not well documented. The authors aimed to compare satisfaction, learning, clinical exposure, and practice intentions between longitudinal family medicine (FM) curricula and traditional rotational ("block") curricula.

Design: This curriculum structure evaluation used a retrospective quasi-experimental study design using data from the College of Family Physicians of Canada Family Medicine Longitudinal Survey.

An Urban Stormwater Contaminant Signature: Defining Priority Contaminants for Urban Stormwater Research.

Stormwater ponds (SWPs) are a common feature of urban landscapes, designed to manage runoff and reduce flooding. Increasingly, they are also recognized as seminatural habitats supporting aquatic biodiversity. However, SWPs receive complex mixtures of contaminants from surrounding urban areas, and the extent of contamination within the ponds themselves remains underexplored.
