La restauration des grands migrateurs rhodaniens et méditerranéens : contribution des sciences biologiques et sociales
2001
In order to warrant the sustainability of migratory fish in the Rhone and Mediterranean area, two policies have been developed. The first one, concerning shads, has already made possible to pass the first three locks and several weirs on the tributaries. Symmetrically, a concerted restoration plan has been elaborated for the restoration of eels populations. Its main objective consists of making resettlement of their habitat, fully performing their ecologically regulating role, and satisfying social and economic requirements. The role of scientists appears to be major, for diagnosing and assessing the ecological justification of the actions, their technical viability (esp. of stocking), and …

Frailty Tools for Assessment of Long-term Prognosis After Acute Coronary Syndrome
2020
Objective: To evaluate the 5 components of the Fried frailty phenotype (self-reported unintentional weight loss, physical activity questionnaire, gait speed, grip strength, and self-reported exhaustion) for long-term outcomes in elderly survivors of acute coronary syndrome. Methods: A total of 342 consecutive patients (from October 1, 2010, to February 1, 2012) were included. The 5 components of the Fried score and albumin concentration, as malnutrition index, were assessed before hospital discharge. Patients were followed up until April 2020 (median follow-up, 8.7 years). The end point was postdischarge all-cause mortality. Results: Mean ± SD age was 77±7 years and mean ± SD Fried score wa…
L'exclusion des ministres communistes du gouvernement en mai 1947
2022
Le 4 mai 1947, les ministres communistes sont exclus du gouvernement, auquel ils participaient depuis la Libération. Dans un contexte de conflictualité sociale et d'exacerbation des tensions géopolitiques, à l'aube de la guerre froide, l'alliance tripartite entre le PCF, la SFIO et le MRP semblait vouée à la rupture. Celle-ci n'était toutefois pas pensée comme définitive par les communistes en mai 1947, de telle sorte que l'on peut distinguer deux dynamiques qui participent successivement au processus d'isolement des communistes : une « exclusion positive » de ces derniers par le reste du gouvernement dans un premier temps, avec la conviction de pouvoir y revenir rapidement, puis un phénomè…
How radical prostatectomy procedures have changed over the last 10 years in Italy: a comparative analysis based on more than 1500 patients participat…
2020
Purpose Therapeutic strategies for prostate cancer (PCa) have been evolving dramatically worldwide. The current article reports on the evolution of surgical management strategies for PCa in Italy. Methods The data from two independent Italian multicenter projects, the MIRROR-SIU/LUNA (started in 2007, holding data of 890 patients) and the Pros-IT-CNR project (started in 2014, with data of 692 patients), were compared. Differences in patients' characteristics were evaluated. Multivariable logistic regression models were used to identify characteristics associated with robot-assisted (RA) procedure, nerve sparing (NS) approach, and lymph node dissection (LND). Results The two cohorts did not …
Pre- and syn-eruptive geochemistry of volcanic gases from Soufriere Hills of Montserrat, West Indies
1998
International audience; Soufriere Hills fumaroles contained magmaderived volatiles before and during the eruption initiated in 1995 but also preserved a typical and quite steady hydrothermal coinposition. Chemical changes due to increased boiling and a greater input of oxidizing magmatic gas occurred only at Galway's Soufriere, the most active fumarolic field. Hydrothermal buffering of the fumaroles has been favoured by their remote location (!-2 km) froin the eruptive vents and by a preferential degassing of the uprising magma through intrusive conduits under the crater. High temperature (720øC) gas collected froin the extruding lava dome in Feb. 1996 was chemically and isotopically repres…
Mathematical models for the diffusion magnetic resonance signal abnormality in patients with prion diseases
2014
In clinical practice signal hyperintensity in the cortex and/or in the striatum on magnetic resonance (MR) diffusion-weighted images (DWIs) is a marker of sporadic Creutzfeldt–Jakob Disease (sCJD). MR diagnostic accuracy is greater than 90%, but the biophysical mechanisms underpinning the signal abnormality are unknown. The aim of this prospective study is to combine an advanced DWI protocol with new mathematical models of the microstructural changes occurring in prion disease patients to investigate the cause of MR signal alterations. This underpins the later development of more sensitive and specific image-based biomarkers. DWI data with a wide a range of echo times and diffusion weightin…

Il ruolo del CNR nel rapporto tra ricerca scientifica e innovazione tecnologica
Alcune osservazioni sugli Enti (pubblici) di ricerca: il loro ruolo e brevi cronache di una devastazione annunciata.
2011
Verranno presentate alcune considerazioni sul ruolo che gli Enti di ricerca dovrebbero (e potrebbero) svolgere nel complesso sistema dell’alta formazione e di quello che ad essa è connesso (dallo sviluppo produttivo al vivere civile). La motivazione di fondo, poi, delle considerazioni che seguono è che la ricerca scientifica può svolgere un ruolo cruciale in tutti questi aspetti in quanto essa è connessa in modo essenziale all’uso di un metodo critico che fa discendere le conclusioni cui essa arriva dalle argomentazioni addotte e non dall’autorità di qualcuno.
