Fish robotics: multi-fin propulsion and the coupling of fin phase, spacing, and compliance.

Fish coordinate the motion of their fins and body to create the time-varying forces required for swimming and agile maneuvers. To effectively adapt this biological strategy for underwater robots, it is necessary to understand how the location and coordination of interacting fish-like fins affect the production of propulsive forces. In this study, the impact that phase difference, horizontal and vertical spacing, and compliance of paired fins had on net thrust and lateral forces was investigated using two fish-like robotic swimmers and a series of computational fluid dynamic simulations.

The Effect of Nutrition on Aging-A Systematic Review Focusing on Aging-Related Biomarkers.

Despite the increasing life expectancy, an individual's later years tends to be accompanied by a decrease in the quality of life. Though biological changes that occur through the natural process of aging cannot be controlled, the risk factors associated with lifestyle can. Thus, the main goal of this systematic review was to evaluate how nutrition can modulate aging.

Electrocardiographic abnormalities, preclinical carotid atherosclerosis and cardiovascular risk in an apparently healthy real-world population. Data from the "No Stroke, No Infarction" project of the Rotary International - district 2110 (Sicily and Malta).

Background: Cardiovascular diseases (CVDs) represent important causes of morbidity and mortality. Our study aimed to evaluate cardiovascular risk using the EuroSCORE, ECG and carotid ultrasound for prevention purpose in a population of companions aged 50-70 years, asymptomatic and without CVD.

Methods: History of CVD, risk factors (RF), ECG and carotid ultrasound were evaluated.

Reverse remodeling and arrhythmic burden reduction in a patient with an implantable cardioverter defibrillator treated with sacubitril/valsartan: Case report.

Sacubitril/valsartan has been shown to reduce cardiovascular mortality and hospitalizations in patients with HFrEF when compared to enalapril. There are also some evidences of its potential antiarrhythmic effects. We present a report where we found a relation between reverse ventricular remodeling and arrhythmic reduction in a patient treated with sacubitril/valsartan.
