Hemodynamic Parameters Change Earlier Than Tissue Oxygen Tension in Hemorrhage
2010
BACKGROUND: Untreated hypovolemia results in impaired outcome. This study tests our hypothesis whether general hemodynamic parameters detect acute blood loss earlier than monitoring parameters of regional tissue beds. MATERIALS AND METHODS: Eight pigs (23-25 kg) were anesthetized and mechanically ventilated. A pulmonary artery catheter and an arterial catheter were inserted. Tissue oxygen tension was measured with Clark-type electrodes in the jejunal and colonic wall, in the liver, and subcutaneously. Jejunal microcirculation was assessed by laser Doppler flowmetry (LDF). Intravascular volume was optimized using difference in pulse pressure (dPP) to keep dPP below 13%. Sixty minutes after p…
Recommendations for the management of patients with aneurysmal subarachnoid hemorrhage
2005
After SAH, primary and secondary complications are frequent and often require neurosurgical interventions to avoid secondary brain damage. The authors of the present paper have summarized the available data about the treatment modalities often used for patients with SAH. The present recommendations have been developed as a neurosurgical and neuroanestesiological consensus. Evidence from prospective, randomized, double blind, placebo-controlled studies support grade A recommendations (standard) for the prophylaxis and treatment of cerebral vasospasm with oral Nimodipine in good grade patients. For intravenous Nimodipine or for oral nimodipine treatment in poor grade patients, available data …
«INTELLIGENTE, IRONICA». OLTRE IL MATRIARCATO, LA DONNA IN ALCUNE OPERE DI LEONARDO SCIASCIA
2021
Intelligente e ironica. Così appare al pittore protagonista del romanzo Todo modo la donna che lascia il marito nello spiazzale antistante L’Eremo di Zafer. Il tempo di uno sguardo, di una breve sequenza. Tuttavia il suo rilievo espressivo travalica la pagina per andare, insieme a tanti piccoli tasselli narrativi di altri racconti, a comporre un’inedita rappresentazione del personaggio femminile. E ciò assume un significato particolare se facciamo attenzione per un momento alle date, se consideriamo per esempio che l’anno di pubblicazione di Todo modo è lo stesso 1974 in cui lo scrittore rilascia la famosa intervista a Franca Leosini che tanto scandalo ha suscitato soprattutto fra le fem…

Cost-distance defined by a topological function of landscape
2008
International audience; Distance is a basic concept in the domain of animal species motion. Cost distances, rather than Euclidian distances, are more and more used in order to have a more realistic measure, on the basis of resistance values assigned to each landscape class. We propose here a method to compute resistance values by using topological functions of landscape, i.e. by taking account of the proximity of habitat/non-habitat edges, with continuous functions. An example is given when comparing cost distances and the propagation of water vole in the massif of Jura (France). The comparison with usual cost distances gives information about the ecological assumptions. The results show al…
Infondate le questioni di legittimità del nuovo comma 1 bis dell’art. 438 c.p.p.: la Corte sigla la conformità costituzionale della preclusione del r…
2021
La Corte costituzionale affronta il delicato tema dei rapporti tra giudizio abbreviato ed ergastolo, di recente riformato dalla legge n. 33 del 2019. Assecondando le istanze securitarie provenienti dalla collettività, il legislatore del 2019, con il nuovo comma 1 bis dell'art. 438 c.p.p., ha stabilito che è inibita la possibilità di accedere al rito premiale per gli imputati di reati puniti con la pena perpetua. Sollevate diverse questioni di legittimità costituzionale, la Corte le ha respinte, siglando la conformità a Costituzione della nuova disciplina. L'Autrice ripercorre il ragionamento dei giudici costituzionali, rilevando come, sulle questioni attinenti al merito della novum legislat…
Extravascular Lung Water Does Not Increase in Hypovolemic Patients after a Fluid-Loading Protocol Guided by the Stroke Volume Variation
2012
Introduction. Circulatory failure secondary to hypovolemia is a common situation in critical care patients. Volume replacement is the first option for the treatment of hypovolemia. A possible complication of volume loading is pulmonary edema, quantified at the bedside by the measurement of extravascular lung water index (ELWI). ELWI predicts progression to acute lung injury (ALI) in patients with risk factors for developing it. The aim of this study was to assess whether fluid loading guided by the stroke volume variation (SVV), in patients presumed to be hypovolemic, increased ELWI or not.Methods. Prospective study of 17 consecutive postoperative, fully mechanically ventilated patients dia…
Island selection on mammalian life-histories: genetic differentiation in offspring size
2008
Abstract Background Since Darwin's pioneering work, evolutionary changes in isolated island populations of vertebrates have continued to provide the strongest evidence for the theory of natural selection. Besides macro-evolutionary changes, micro-evolutionary changes and the relative importance of natural selection vs. genetic drift are under intense investigation. Our study focuses on the genetic differentiation in morphological and life-history traits in insular populations of a small mammal the bank vole Myodes glareolus. Results Our results do not support the earlier findings for larger adult size or lower reproductive effort in insular populations of small mammals. However, the individ…
Excretion and measurement of corticosterone and testosterone metabolites in bank voles (Myodes glareolus)
2017
The bank vole is a commonly used model species in behavioral and ecophysiological studies. Thus, presenting a validated method for noninvasive monitoring of corticosterone and testosterone secretion is of high relevance. Here, we evaluated the effect of time of day and an ACTH challenge test on measured fecal corticosterone (FCM) and testosterone (FTM) metabolites in both sexes. Furthermore, we performed radiometabolism experiments for both steroids and sexes to study metabolism and excretion of 3H-corticosterone and 3H-testosterone. FCM and FTM were analysed with a 5α-pregnane-3β,11β,21-triol-20-one enzyme immunoassay (EIA) and a testosterone (measuring 17β-hydroxyandrostanes) EIA, respect…
