Multigram-Scale Synthesis of Luminescent Cesium Lead Halide Perovskite Nanobricks for Plastic Scintillators.

Cesium lead halide perovskite nanocrystals of general formula CsPbX are having tremendous impact on a vast array of technologies requiring strong and tunable luminescence across the visible range and solutions processing. The development of plastic scintillators is just one of the many relevant applications. The syntheses are relatively simple but generally unsuitable to produce a large amount of material of reproducible quality required when moving from proof-of-concept scale to industrial applications.

Impact of different treatment of whole-body cryotherapy on circulatory parameters.

Cryotherapy is commonly used as a procedure to relieve pain symptoms, particularly in inflammatory diseases, injuries and overuse symptoms. A peculiar form of cold therapy or stimulation was proposed 30 years ago for the treatment of rheumatic diseases. The therapy consists in the exposure to very cold air in special cryochambers.

Anatomical patterns of patent foramen ovale (PFO): do they matter for percutaneous closure?

Aim: The aim of this study was to describe and classify the various anatomical pattern of patent foramen ovale (PFO) with transesophageal echocardiography (TEE) and to relate such classification to the selection of PFO closure devices.

Methods: This study enrolled 216 PFO patients (118 females) mostly with previous cryptogenic stroke or transitory ischemic attack (TIA) who underwent percutaneous closure of PFO with deep sedation under TEE control. Anatomical patterns were classified as follows: simple: PFO characterised by central/superior eccentric shunt or with a valve mechanism (45%); reduse: widely redundant septum primum (22%); ASA: atrial septal aneurysm (11%); EASA: entire atrial septal aneurysm (1.

[Right ventricular heart failure in hyperthyroidism].

Cardiovascular disorders in patients affected with hyperthyroidism are very common; the increase in the heart rate and in inotropism combines with a rise in the cardiac index towards which the reduction in peripheral resistances and an increase in the venous return to the heart contribute. The increase in myocardial excitabi1ity, caused above all by triiodothyronine, may be attended with atrial extrasystoles or even with atrial fibrillation. Congestive heart failure during hyperthyroidism, even if rare, may either reveal itself in association with pre-existent cardiopathy or to be precipitated by tachyar-rhythrmia, particu1arly, by paroxysmal atrial fibrillation.

[Mild hypercholesterolemia. Diagnosis and prognosis].

The finding of normocholesterolaemia, characterized by plasmatic values of total cholesterol < 2 g/l, which may hide silent lipidic alterations, is not by itself sufficient to rule out the existence of cardiovascular risk. First level screening of patients exposed to atherogenic risk must begin from dosage of three basic lipidic indicators, represented by total cholesterol, triglycerides, and HDL cholesterol. By using the values of the three above-mentioned indicators and by applying Friedewald's formula, it is possible to calculate LDL cholesterol indirectly.
