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.

Pharmacological activity of the new calcium antagonist, lacidipine, on isolated preparations.

1. The calcium-channel blocking activity of lacidipine has been studied compared with that of nifedipine and verapamil on the isolated rabbit heart and aorta. 2.

[The prognosis of the patient with heart failure: an analysis of the most significant clinical and instrumental parameters].

Despite the progress of the medical and surgical therapy of cardiac failure, the prognosis of this syndrome remains severe. We studied in a group of cardiac failure patients (n = 203; 18-74 years old) admitted in our division from 1982 to 1987 the most significant clinical and instrumental parameters of prognostic importance. The clinical parameters considered were: age, sex, heart rate, blood pressure, NYHA class, presence of mitral insufficiency, episodes of acute heart failure.

Hemodynamic advantage of combined administration of oral ibopamine and nitroprusside in patients with ischemic and idiopathic congestive cardiomyopathy.

The hemodynamic effects of combined administration of ibopamine (Ib) (150 mg orally) with nitroprusside (NP) (50-150 micrograms/min intravenously) were compared with those of NP alone in 17 patients with severe congestive heart failure due to coronary artery disease (7 patients) or idiopathic cardiomyopathy (10 patients). Hemodynamic measurements were obtained using a Swan-Ganz thermodilution catheter and a bedside thermodilution cardiac output computer. Nitroprusside alone produced a significant decrease (-12.

Hemodynamic effects of ibopamine in patients with idiopathic congestive cardiomyopathy.

We administered 150 mg of ibopamine orally to 10 patients suffering from idiopathic congestive cardiomyopathy. Hemodynamic function was evaluated by right heart catheterization and by measurement of cardiac output with the thermodilution technique. Ibopamine caused no significant change in heart rate or mean arterial pressure.

[Effectiveness and duration of action of nifedipine in effort angina (author's transl)].

The anti-anginal activity of nifedipine was studied after a dosage of 10 and 20 mg in nine patients suffering from a typical, stable effort angina pectoris. The effectiveness and the duration of action of nifedipine was evaluated by serial cycloergometer exercise testing repeated after the administration of the two dosage of nifedipine, for six hours. Nifedipine significantly increased exercise tolerance before angina pectoris, with an action lasting at least two hours after 10 mg and six hours after 20 mg.

Cardiovascular effects induced by the injection of a new nonionic contrast medium (Iopamidol): experimental study in dogs.

The hemodynamic effects induced by the injection in the pulmonary artery of the new nonionic water soluble contrast medium Iopamidol were compared with those obtained by the injection of two other currently used contrast media (meglumine diatrizoate and sodium iothalamate). The experiments were carried out in nine mongrel dogs. Hemodynamic variables were continuously measured prior to, during, and for 8 minutes after injection of the contrast media.

[The efficacy of the angiographical method in the evaluation of left ventricular muscle mass in the dog (author's transl)].

In nine closed chest mongrel dogs 42 left ventricular cineangiographies for determination of left ventricular muscle mass were carried out. Buetterich's method was verified and a different procedure of calculation of myocardial wall thickens was proposed. By this method a better correlation line between calculated and weighed left muscle mass and a lower standard error of estimate is obtained.
