Functional ecological patterns and the effect of anthropogenic disturbances on a recently restored Mediterranean coastal lagoon. Needs for a sustaina…

2012

Abstract We present here a detailed case study on the lessons learned after a restoration process of a natural ecosystem, which can be considered as an ecological experiment. Senillar de Moraira is a brackish water small coastal lagoon located in the Spanish Mediterranean coast. It is separated from the sea by a sand bar and a beach, and is regularly fed by groundwater. Mostly due to the strong anthropogenic pressure this lagoon was degraded, and a restoration process, consisting mostly on the rebuilt of hydrogeomorphological features, was accomplished about a decade ago. After the restoration project, ecological monitoring was performed to reveal the recovery of the ecological integrity of…

Activity and toxicity of oxaliplatin plus raltitrexed in 5-fluorouracil refractory metastatic colorectal adeno-carcinoma

2004

Background: This study evaluated the antitumor efficacy and safety of a novel oxaliplatin/raltitrexed combination in pretreated advanced colorectal cancer patients. Patients and Methods: Forty-five patients with 5-fluorouracil-refractory metastatic colorectal cancer received raltitrexed 3.0 mg/m2 as a 15-minute intravenous (i.v.) infusion, followed 45 min later by l-OHP 130mg/m2 iv as 2-h venous infusion on 1 day every 3 weeks. All patients had histologically proven metastatic colorectal cancer, age 18-75, measurable disease and normal baseline biological values. Most patients (60%) had >2 disease sites. All patients were assessed for safety and also for response according to an intent-to-t…

A high precision calorimeter for hunting the sterile neutrino in the SOX experiment

2019

Abstract A thermal calorimetric apparatus was designed, built and calibrated for measuring the activity of the artificial 144 Ce —144 Pr antineutrino source. This measurement will be performed at the Laboratori Nazionali del Gran Sasso in Italy, just before the source insertion in the tunnel under the Borexino detector and a precision better than 1% is required for a disappearance technique measurement in the SOX (Short distance neutrino Oscillation with BoreXino) project. In this work the apparatus is described and the most important results from the calibration measurements are shown, where the final precision of few per thousand is demonstrated.

NEW LIGHT ON PARASOREX DEPERETI (ERINACEOMORPHA: ERINACEIDAE: GALERICINI) FROM THE LATE MESSINIAN (MN 13) OF THE MONTICINO QUARRY (BRISIGHELLA, FAENZ…

2019

A large-sized species of Parasorex is common in the MN 13 mammal assemblages from the uppermost Messinian sandy-marly fissure fillings within the Gessoso Solfifera Formation at Brisighella (Northern Apennine). This erinaceid has been classified as Galerix sp. in the first papers on the Brisighella fauna. Later, it was described in detail in an unpublished Ph.D. dissertation by Fanfani (1999), who referred it to Galerix depereti. Van den Hoek Ostende (2001) included G. depereti in the genus Parasorex, Parasorex depereti has been described by Crochet (1986) on scarce material from a few Early Pliocene (MN 14–15) localities of southern France and Spain. Parasorex cf. depereti has been reported…

GLI INSETTIVORI DI CAVA MONTICINO (BRISIGHELLA, RA)

2021

Sono note quattro diverse specie di insettivori dalla cava del Monticino, due soricidi (Neomyosorex sp. e cf. Miosorex desnoyersianus) e due erinaceidi (Parasorex depereti e “Mioechinus” sp.). Parasorex depereti appartiene ai Galericini, una tribù estinta di gimnuri, e probabilmente era un animale piuttosto opportunista, come gli altri membri dello stesso genere, forse non legato ad ambienti di foresta o umidi relativamente caldi. “Mioechinus” sp. di collocazione sistematica incerta, per alcuni autori potrebbe essere sinonimo dei generi di ricci moderni Atelerix o Hemiechinus. In questo caso, la sua presenza escluderebbe ambienti desertici o di foresta pluviale. Infine, Neomyosorex sp., rel…

An examination of the impact of care giving styles (accommodation and skilful communication and support) on the one year outcome of adolescent anorex…

2016

Abstract Background The cognitive interpersonal model predicts that parental caregiving style will impact on the rate of improvement of anorexia nervosa symptoms. The study aims to examine whether the absolute levels and the relative congruence between mothers' and fathers' care giving styles influenced the rate of change of their children's symptoms of anorexia nervosa over 12 months. Methods Triads ( n =54) consisting of patients with anorexia nervosa and both of their parents were included in the study. Caregivers completed the Caregiver Skills scale and the Accommodation and Enabling Scale at intake. Patients completed the Short Evaluation of Eating Disorders at intake and at monthly in…

Absence of a day-night asymmetry in the7Be solar neutrino rate in Borexino

2012

We report on a search for the day-night asymmetry of the Be-7 solar neutrino rate measured by Borexino at the Laboratori Nazionali del Gran Sasso (LNGS), Italy. The measured value, Adn=0.001 +- 0.012 (stat) +- 0.007 (syst), shows the absence of a significant asymmetry. This result alone rejects the so-called LOW solution at more than 8.5 sigma. Combined with the other solar neutrino data, it isolates the Large Mixing Angle (LMA) -- MSW solution at DeltaChi2 > 190 without relying on the assumption of CPT symmetry in the neutrino sector. We also show that including the day-night asymmetry, data from Borexino alone restricts the MSW neutrino oscillations to the LMA solution at 90% confidence l…

A test of electric charge conservation with Borexino

2015

Borexino is a liquid scintillation detector located deep underground at the Laboratori Nazionali del Gran Sasso (LNGS, Italy). Thanks to the unmatched radio-purity of the scintillator, and to the well understood detector response at low energy, a new limit on the stability of the electron for decay into a neutrino and a single mono-energetic photon was obtained. This new bound, tau > 6.6 10**28 yr at 90 % C.L., is two orders of magnitude better than the previous limit.

Short distance neutrino oscillations with Borexino

2014

International audience; The Borexino detector has convincingly shown its outstanding performances in the low energy, sub-MeV regime through its unprecedented accomplishments in the solar and geo-neutrinos detection. These performances make it the ideal tool to accomplish a state-of-the-art experiment able to test unambiguously the long-standing issue of the existence of a sterile neutrino, as suggested by the several anomalous results accumulated over the past two decades, i.e. the outputs of the LSND and Miniboone experiments, the results of the source calibration of the two Gallium solar neutrino experiments, and the recently hinted reactor anomaly. The SOX project will exploit two source…

Objective: Severe malnutrition in patients with anorexia nervosa (AN) as well as possible trait-related aberrations lead to pronounced structural brain changes whose reversibility after recovery is currently unclear. Previous diffusion tensor imaging (DTI) studies investigating white matter (WM) microstructure alterations in AN are inconsistent. Methods: In this so far largest DTI study in adults, we investigated 33 AN patients, 20 recovered (REC), and 33 healthy women. DTI data were processed using the "DTI and Fiber tools," and the Computational Anatomy Toolbox. WM integrity, both in terms of fractional anisotropy (FA) and mean diffusivity (MD), was assessed. Results: We found a significa…
