Global peak systolic longitudinal strain (PLS) derived from speckle tracking echocardiography (STE) is a widely used left ventricular deformation parameter. Modern ultrasound systems with improved temporal resolution and new software now allow automated multilayer analysis; however, there is limited evidence regarding its reproducibility. We performed intra- and inter-observer analyses within a population-based cohort study using conventional quantitative strain analysis (GE Healthcare). Fifty patients (49 ± 14 years) were randomly selected among the fourth visit of the STANISLAS Cohort...

Two-dimensional speckle tracking echocardiography (2D-STE) multilayer analysis of myocardial deformation is a non-invasive method that enables discrimination of transmural differences owing to myocardial ischemia or necrosis. We wished to ascertain if multilayer longitudinal strains at rest are associated with significant (≥70 %) stenosis of the left anterior descending coronary artery (LAD) in patients with suspected non-ST-elevation acute coronary syndrome (NSTE-ACS). Our cohort comprised 113 consecutive patients with suspected NSTE-ACS and preserved ejection fraction (EF)...

Hagfishes (Myxinidae) often integrate whole-body knotting movements with jawless biting motions when reducing large marine carcasses to ingestible items. Adaptations for these behaviors include complex arrangements of axial muscles and flexible, elongate bodies without vertebrae. Between the axial muscles and the hagfish skin is a large, blood-filled subcutaneous sinus devoid of the intricate, myoseptal tendon networks characteristic of the taut skins of other fishes. We propose that the loose-fitting skin of the hagfish facilitates the formation and manipulation of body knots, even if it is of little functional significance to steady swimming...
