Importance: Nitric oxide deficiency may contribute to exercise intolerance in patients with heart failure with preserved ejection fraction (HFpEF). Prior pilot studies have shown improvements in exercise tolerance with single-dose and short-term inorganic nitrate administration.
Objective: To assess the impact of chronic inorganic nitrate administration on exercise tolerance in a larger trial of participants with HFpEF.
Single-crystalline nanoparticles play an increasingly important role in a wide variety of fields including pharmaceuticals, advanced materials, catalysts for fuel cells, energy materials, as well as environmental detection and monitoring. Yet, the deformation mechanisms of very small nanoparticles are still poorly understood, in particular the role played by single dislocations and their interaction with surfaces. In this work, silver nanoparticles with particularly small dimensions (≈20 nanometers in diameter) are compressed in situ in an aberration-corrected transmission electron microscopy (TEM) and molecular dynamics (MD) simulations.

- This study investigated the bacterial microbiota affecting spoilage in three fish species during ice and frozen storage, using advanced sequencing and NMR analysis to track changes over time.
- The storage conditions significantly influenced the diversity of bacteria present, with key spoilage bacteria identified, including Pseudomonas and Bacillus species, which were linked to specific metabolic pathways.
- Findings revealed that P. fragi was the most common spoilage bacteria in both storage types, and chemical changes like amino acid and acetic acid increases indicated spoilage progression during ice storage.
This study aimed to assess the impact of adaptation of ten strains of O157:H7 and non-O157 Escherichia coli to low pH (acid shock or slow acidification) and the effects of this exposure or not on the resistance of E. coli strains to UV radiation in orange juice (pH 3.5).

The resistance to chlorine-based sanitizers, ability to attach to stainless steel surfaces, and antibiogram profile of a large set of S. aureus strains (n = 585) were assessed.
