A randomized clinical trial on the short‐term effects of 12‐week sacubitril/valsartan vs. enalapril on peak oxygen consumption in patients with heart failure with reduced ejection fraction: results from the <span>ACTIVITY‐HF</span> study Open
Aims ACTIVITY‐HF was a randomized, double‐blind, active‐controlled study, which assessed the short‐term effect of sacubitril/valsartan compared with the active comparator enalapril on improving maximal exercise capacity in patients with he…

Temporal and Spatial Niche Partitioning of Bumblebee Species (Apidae:<i>Bombus</i>) on a Himalayan Mountain Open
Background Bumblebees are essential pollinators in many ecosystems. To maintain such ecosystem functions, bumblebee diversity remains an important concern. We measured abundance and diversity of bumblebee species along an elevational gradi…

<i>Cypripedium wardii</i>(Orchidaceae) employs pseudopollen with both reward and deception to attract both flis and bees as pollinators Open
Flowering plants always attract animals providing rewards or deceptive signals to gain reproductive success. However, there is no well-documented reporting about a pollination mechanism with both rewards and deceptive signals by a same obj…

Non-invasive determination of pressure recovery by cardiac MRI and echocardiography in patients with severe aortic stenosis: short and long-term outcome prediction Open
Objective To assess the influence of pressure recovery (PR)-corrected haemodynamic parameters on outcome in patients with aortic stenosis. Methods Aortic stenosis severity parameters were corrected for PR (increase in static pressure due t…

The diversity and evolution of pollination systems in large plant clades: Apocynaceae as a case study Open
Within Apocynaceae, interactions with pollinators are highly structured both phylogenetically and biogeographically. Variation in transition rates between pollination systems suggest constraints on their evolution, whereas regional differe…

Does reproductive isolation reflect the segregation of color forms in <i>Spiranthes sinensis</i> (Pers.) Ames complex (Orchidaceae) in the Chinese Himalayas? Open
Isolation between species, or taxa sharing a common lineage, depends primarily on the relative strengths of various reproductive barriers. Previous studies on reproductive isolation between orchids emphasized mechanical and ethological bar…

Comparative pollination ecology between two populations and two varieties of Cypripedium parviflorum (Orchidaceae) in Missouri, United States of America – does size matter? Open
The pollination ecology of two sympatric varieties of Cypripedium parviflorum was compared to determine whether floral dimensions had an impact upon potential pollinator diversity. We observed, collected and compared 235 insects that enter…

Cardiac magnetic resonance imaging derived quantification of myocardial ischemia and scar improves risk stratification and patient management in stable coronary artery disease Open
Quantification of myocardial ischemia and LGE was shown to significantly improve existing risk prediction models and might thus lead to an improvement in patient management.

Fitness-related selection on floral traits in the distylous plant<i>Primula poissonii</i>(Primulaceae) Open
Reproductive fitness of different floral phenotypes varies within and/or among populations. These variations are important to understand the process of natural selection and the evolution of floral traits. In this study, we focused on a di…
