La cura di sé come pratica educativa: le radici ellenistiche

2012

The “self-care”, yet one of the ethical principles of the hellenistic philosophies, is read again with a kind of disenchanted and post-modern view. Through a comparision between the Hellenistic and the modern ages, we can say that the first one is marked by the crisis of the pòlis, and the second one is living out the end of the national state with a sense of anxiety. So, by following Epicuro and the Stoicism, is possible to recognize in the practice of the “self-care” a pedagogic resource through which the Subject can activate a self-inquiry process able to involve or commit others human beings, planting the seeds for a planetary consciousness.

Lipase-catalyzed resolution of β-hydroxy selenides

2006

Abstract Eleven β-hydroxy selenides were kinetically resolved using an immobilized lipase (Amano PS-C II) in toluene in the presence of vinyl acetate at 30 °C. This approach provided, in several cases, both enantiomers in high enantiomeric excess. The role of the size of substituents and the behaviour of cyclic β-hydroxy selenides is also discussed. Enantiopure β-hydroxy selenides are useful building blocks. As an application of this chemistry, enantiopure (1 S ,2 R )-indene oxide was obtained in one step from the proper enantiopure β-hydroxy selenide.

STUDIO MINERALOGICO-PETROGRAFICO E PROBLEMI CONSERVATIVI

2011

Il capitolo illustra le risultanze dello studio delle problematiche conservative e della caratterizzazione mineralogico petrografica dei materiali lapidei del teatro ellenistico di Morgantina (Enna). Tale attività è stata finalizzata alla definizione dell'intervento conservativo del teatro. The chapter illustrates the results of the study of conservation issues and petrographic mineralogical characterization of the stone materials of the Hellenistic theater of Morgantina (Enna). This activity was aimed at defining the conservative intervention of the theatre.

The metabolism and availability of essential fatty acids in animal and human tissues.

1994

Essential fatty acids (EFA), which are not synthesized in animal and human tissues, belong to the n-6 and n-3 families of polyunsaturated fatty acids (PUFA), derived from linoleic acid (LA, 18:2n-6) and alpha-linolenic acid (LNA, 18:3n-3). Optimal requirements are 3-6% of ingested energy for LA and 0.5-1% for LNA in adults. Requirements in LNA are higher in development. Dietary sources of LA and LNA are principally plants, while arachidonic acid (AA, 20:4n-6) is found in products from terrestrian animals, and eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are found in products from marine animals. EFA are principally present in dietary triacylglycerols, which should be hydrolyze…

Duplexsonographische Untersuchungen zur Pathogenese der lienalen Hämodynamik bei Leberzirrhose

2008

AIM OF STUDY The haemodynamic role of the spleen in portal hypertension remains unclear. Duplex sonography was undertaken prospectively to discover the relationship of splenomegaly and splenic vein flow to type and severity of liver cirrhosis and portal vein flow, as well as to the degree of oesophageal varices. PATIENTS AND METHODS 89 patients (54 men, 35 women; mean age 52 [26-81] years), diagnosed in the second half of 1993 as having liver cirrhosis were consecutively included in the study. In 40 patients the cirrhosis was in stage A (according to Child-Pugh classification), in 31 in stage B and in 18 in stage C. RESULTS Portal vein flow fell significantly with increasing degree of cirrh…

Splenic Marginal Zone Lymphoma: French Registries Population-Based Treatment and Survival Analyses (2002-2014)

2020

Background. Splenic Marginal Zone Lymphoma (SMZL) is a rare indolent B-cell lymphoma characterized by a massive splenomegaly and a moderate lymphocytosis. There is no standard of care for SMZL so far. The treatment is indicated if constitutional symptoms, massive splenomegaly and/or cytopenia, after a watch and wait period that is highly variable. Rituximab with or without chemotherapy, chemotherapy, and splenectomy are valid treatment approaches. Our objectives were to describe the characteristics of the patients with SMZL retrospectively collected from a French population database, to analyze the treatments received in first line (Tt1) and in second line (Tt2) in term of efficacy, and to …

Splenic respiratory gas exchange and glucose uptake in patients with splenomegaly in hypersplenism and Hodgkin's disease.

1977

Blood samples are taken from the splenic artery, vein and pulp of patients suffering from Hodgkin's disease (n=10) or hypersplenism (n=7) and undergoing splenectomy. In these samples, the relevant parameters of the respiratory gas exchange as well as glucose and lactate concentrations are determined. In hypersplenism (mean splenic wet weight: 543 g) the mean oxygen consumption of the splenic tissue amounts to 0.9 ml O2/100 g/min taking into account a mean splenic blood flow of 80 ml/100 g/min. The glucose uptake and the lactate release are 9 mg/100 g/min and 5.5 mg/100 g/min, respectively. These values are in close agreement with the results obtained in the normal and undisturbed spleen in …

Prooxidative toxicity and selenoprotein suppression by cerivastatin in muscle cells

2012

Statins are the most widely used drugs for the treatment of hypercholesterolemia. In spite of their overall favorable safety profile, they do possess serious myotoxic potential, whose molecular origin has remained equivocal. Here, we demonstrate in cultivated myoblasts and skeletal muscle cells that cerivastatin at nanomolar concentrations interferes with selenoprotein synthesis and evokes a heightened vulnerability of the cells toward oxidative stressors. A correspondingly increased vulnerability was found with atorvastatin, albeit at higher concentrations than with cerivastatin. In selenium-saturated cells, cerivastatin caused a largely indiscriminate suppression of selenoprotein biosynth…

Hemosuccus pancreaticus--a rare cause of gastrointestinal bleeding: diagnosis and interventional radiological therapy.

2000

Hemorrhage from the pancreatic duct, i.e. hemosuccus pancreaticus (HP), is a rare cause of gastrointestinal bleeding. Pancreatic hemosuccus is usually due to the rupture of an aneurysm of a visceral artery, most likely the splenic artery, in chronic pancreatitis. Other causes of HP are rare. We present a case of HP in a female patient with no history but with positive findings of chronic calcifying pancreatitis upon ultrasonographic investigation, computed tomography scan, and endoscopic retrograde cholangiopancreatography. With detectable fresh blood in the descending duodenum, angiography of the celiac artery revealed an aneurysm of the splenic artery as the suspected cause of intermitten…
