Relationship Between Left Atrial Strain and Atrial Fibrillation: The Role of Stress Echocardiography.

Interest in advanced echocardiographic imaging methods is growing. Left atrial strain (LAS) is among recently developed echocardiographic parameters. LAS represents an index of tissue deformation of the left atrium (LA).

Mitochondrial Dysfunction in Atrial Fibrillation: The Need for a Strong Pharmacological Approach.

Despite great progress in treating atrial fibrillation (AF), especially with the development of increasingly effective invasive techniques for AF ablation, many unanswered questions remain regarding the pathogenic mechanism of the arrhythmia and its prevention methods. The development of AF is based on anatomical and functional alterations in the cardiomyocyte resulting from altered ionic fluxes and cardiomyocyte electrophysiology. Electric instability and electrical remodeling underlying the arrhythmia may result from oxidative stress, also caused by possible mitochondrial dysfunction.

Complete genomes of SNA2 and sp. cycad4: microbes with the potential for plant growth promotion.

species have been isolated from various environments, often in association with plants. Here, we report the complete genomes of SNA2 and sp. cycad4.

Complete genome of sp. EBFNA2, isolated from a surface-sterilized fava bean nodule.

We report the complete genome sequence of sp. EBFNA2, a fava bean nodule endophyte. The strain appears to be a new species, and its genome provides insight into its interactions with host plants and potential to promote plant growth and crop yield.
