Three-dimensional muon imaging of cavities inside the Temperino mine (Italy).

Muon radiography (muography) is an imaging technique based on atmospheric muon absorption in matter that allows to obtain two and three-dimensional images of internal details of hidden objects or structures. The technique relies on atmospheric muon flux measurements performed around and underneath the object under examination. It is a non-invasive and passive technique and thus can be thought of as a valid alternative to common prospecting techniques used in archaeological, geological and civil security fields.

Tests of a novel imaging algorithm to localize hidden objects or cavities with muon radiography.

A novel algorithm developed within muon radiography to localize objects or cavities hidden inside large material volumes was recently proposed by some of the authors (Bonechi 2015 , P02003 (doi:10.1088/1748-0221/10/02/P02003)). The algorithm, based on muon back projection, helps to estimate the three-dimensional position and the transverse extension of detected objects without the need for measurements from different points of view, which would be required to make a triangulation.

Survival and hospitalization in a nurse-led domiciliary intervention for elderly heart failure patients.

Aim: Heart failure in the elderly population represents a complex clinical situation associated with frequent hospitalizations and numerous comorbidities. The present study aimed to evaluate the impact of a domiciliary-based nurse-led strategy in a group of very elderly patients affected by heart failure who were regularly seen at an outpatient heart failure clinic (HFC).

Methods: Patients were periodically assessed in their homes by two trained nurses under supervision of the cardiologists of the HFC.

Primary angioplasty for acute myocardial infarction in a patient with a solitary coronary ostium and a "superdominant" right coronary artery.

Coronary artery anomalies (CAAs) are a rare angiographic finding, sometimes associated with acute coronary events. We report on a case of primary angioplasty for inferior acute myocardial infarction (AMI) in a 66-year-old woman with a solitary coronary ostium in the right sinus of Valsalva and a "superdominant" right coronary artery. We also discuss two potential pitfalls of primary angioplasty: correct interpretation of coronary anatomy and approach to challenging lesions.
