Abnormal Exercise Electrocardiography With Normal Stress Echocardiography Is Associated With Subclinical Coronary Atherosclerosis.

Background: Patients with abnormal (positive) exercise electrocardiography, but normal stress echocardiography (+ECG/-Echo), have an increased risk of adverse cardiovascular events compared with patients with a normal (negative) ECG and a normal stress Echo (-ECG/-Echo). However, it is unclear if +ECG/-Echo discordance is associated with a greater burden of subclinical coronary atherosclerosis.

Methods: Project Baseline Health Study participants who underwent a stress Echo and coronary artery calcium (CAC) scan were stratified by stress Echo result: -ECG/-Echo or +ECG/-Echo.

Proteomic Insights into the Molecular Correlations Between Coronary Artery Disease and Peripheral Artery Disease in the Project Baseline Health Study.

Coronary artery disease (CAD) and peripheral artery disease (PAD) are common and dangerous conditions that are both driven by atherosclerosis. Despite sharing many major risk factors, their disease pathophysiology is not fully understood. In this study, we aimed to better distinguish common vs.

Horticultural additives influence peat biogeochemistry and increase short-term CO production from peat.

Aims: Peat is used as a major ingredient of growing media in horticulture. Peat extracted from bogs can be acidic and low in nutrient availability and is therefore mixed with liming agents, nutrients, surfactants, perlite and so on. This study aims to estimate the rates at which raw peat and the modified peat ('growing media') decompose to release carbon dioxide (CO), to estimate the release of carbon (C) from liming agents and to estimate how peat biogeochemistry is changed.

Representation of Women Among Cardiology Grand Rounds Speakers in the United States.

Importance: Women are underrepresented in leadership positions in cardiology. Institutional grand rounds (GR) are platforms through which faculty can gain professional exposure and access to career development opportunities. The gender diversity of invited cardiology GR speakers has not been investigated.

Isotopic and molecular analyses of n-alkanes in a temporal study of coastal sediment contributions to organic carbon degradation induced by algal bloom and terrestrial runoff.

The priming effect (PE) refers to the enhanced remineralization of recalcitrant organic carbon (OC) driven by the respiration of labile OC, potentially increasing CO fluxes from aquatic ecosystems. Patterns of PE induced by marine and terrestrial OC inputs can be explored through sedimentary contributions to the degraded OC pool. In this study, coastal sediments (δC = -25.
