Article Synopsis
- The study investigates how factors like plant species, temperature, and microbial competition affect the composition of microbes in floral nectar, which is important for plant health and pollination.
- By inoculating yeasts and bacteria into nectars of 31 plant species and analyzing the resulting communities, researchers found that plant species strongly influence microbial abundance and composition, with variations attributed to plant phylogeny and nectar peroxide content.
- Higher temperatures were shown to decrease microbial diversity and affect growth; consistent microbial communities could help plants and pollinators adapt, highlighting the significance of host identity and environmental conditions in microbial community dynamics.
Background: This study aimed to assess the diagnostic value and safety of using Pulmonary Embolism Rule-Out Criteria (PERC) in an emergency care setting.
Methods: We conducted a retrospective application of the PERC to the patients suspected of having pulmonary embolism (PE) and who underwent computed tomography pulmonary angiogram (CTPA) Karolinska University Hospital's emergency department (ED) from 2016 to 2017. The patient data, including D-dimer (DD) and ED waiting times were extracted from the Karolinska Venous Thromboembolism cohort (VTE cohort).
Aims: Mineralocorticoid receptor antagonists (MRA) improve outcomes in heart failure with reduced ejection fraction (HFrEF) but are underused. Point prevalent use has been described, but the kinetics of discontinuation and the extent of reinitiation have not been studied.
Methods And Results: Patients with HFrEF enrolled in the Swedish Heart Failure Registry between 2006 and 2021 were linked to the Prescribed Drug Register.
Chemically labile ester linkages can be introduced into lignin by incorporation of monolignol conjugates, which are synthesized in planta by acyltransferases that use a coenzyme A (CoA) thioester donor and a nucleophilic monolignol alcohol acceptor. The presence of these esters facilitates processing and aids in the valorization of renewable biomass feedstocks. However, the effectiveness of this strategy is potentially limited by the low steady-state levels of aromatic acid thioester donors in plants.

Objectives: This study sought to investigate the association between treatment with PDE5i or alprostadil and outcomes in men with stable coronary artery disease.
Methods: All Swedish men with a prior MI or revascularization who received PDE5i or alprostadil during 2006 through 2013 at >6 months after the event were included, using the Swedish Patient Register and the Swedish Prescribed Drug Register.
