Lowermost Jurassic dinosaur ecosystem from the Bleymard Strait (southern France): sedimentology, mineralogy, palaeobotany and palaeoichnology of the …
2021
AbstractWe report the first Hettangian theropod tracksite (~200 Ma) yielding a rich accumulation of plant remains from the Bleymard Strait (southern France). It constitutes an excellent opportunity to reconstruct lowermost Jurassic ecosystems hosting dinosaurs and which are still poorly documented in this area. Two morphotypes of tridactyl tracks are distinguished. They share similarities with Grallator and Kayentapus. Plant-bearing beds yield abundant leafy axes (Pagiophyllum peregrinum), male cones (Classostrobus sp.), wood (Brachyoxylon sp.) and pollen of conifers (Classopollis classoides). Sedimentological, petrological and mineralogical analyses demonstrated that, in the Dolomitic Form…
Alemtuzumab (Campath-1H) and CHOP chemotherapy as first-line treatment of peripheral T-cell lymphoma: results of a GITIL (Gruppo Italiano Terapie Inn…
2007
To evaluate in a prospective multicenter trial the feasibility and clinical efficacy of the combination of alemtuzumab (Campath-1H) with the cyclophosphamide/doxorubicin/vincristine/prednisone (CHOP) regimen (CHOP-C) as the primary treatment for patients with peripheral T-cell lymphoma (PTCL), between January 2003 and December 2005, 24 consecutive patients with PTCL entered the study and received 8 CHOP courses. Alemtuzumab was added at 30 mg subcutaneously at day −1 initially to the first 4 courses (4 patients), and then to all 8 courses (20 patients). Complete remission (CR) was achieved in 17 (71%) patients, 1 had partial remission, and 6 had stable/progressive disease. At a median follo…
Pas de titre
2011
A number of phonetic and phonological changes have lately been observed in most geographical varieties of British English. This phenomenon seems to have been accelerated by increasing social and geographical mobility in the past decades. Based on a corpus mainly consisting of several hours of spontaneous interaction between a number of native NW Yorkshire speakers divided into different age groups, this research identifies and analyses several segmental and suprasegmental innovations observed in apparent time in a set of accents associated with a circumscribed geographical area. This thesis discusses the motivation behind some of these changes and addresses the question of whether the same …
Thalamic relay or cortico-thalamic processing? Old question, new answers.
2013
Ascending and descending information is relayed through the thalamus via strong, “driver” pathways. According to our current knowledge, different driver pathways are organized in parallel streams and do not interact at the thalamic level. Using an electron microscopic approach combined with optogenetics and in vivo physiology, we examined whether driver inputs arising from different sources can interact at single thalamocortical cells in the rodent somatosensory thalamus (nucleus posterior, POm). Both the anatomical and the physiological data demonstrated that ascending driver inputs from the brainstem and descending driver inputs from cortical layer 5 pyramidal neurons converge and interac…
Simulation of Supralevator Abscesses and Complex Fistulas in Cadavers: Pelvic Dissemination and Drainage Routes
2018
BACKGROUND: Most perianal abscesses have a cryptoglandular origin, following the pathogenesis described by Parks in 1961. Supralevator abscesses have the most uncommon location. Nevertheless, such pathology results in a high morbidity because of their difficult diagnosis and treatment. OBJECTIVE: This study aimed to deepen the knowledge of the pathogenesis and management of supralevator abscesses, as well as the complications derived from incorrect treatment, by using simulation in cadavers. DESIGN: This study is an anatomosurgical description of pelvic and perianal zone and simulation of the different types of supralevator abscesses, their correct drainage routes, and secondary complex fis…
Microbial communities of the Mediterranean rocky shore: ecology and biotechnological potential of the sea‐land transition
2019
Microbial communities from harsh environments hold great promise as sources of biotechnologically relevant strains and compounds. In the present work, we have characterized the microorganisms from the supralittoral and splash zone in three different rocky locations of the Western Mediterranean coast, a tough environment characterized by high levels of irradiation and large temperature and salinity fluctuations. We have retrieved a complete view of the ecology and functional aspects of these communities and assessed the biotechnological potential of the cultivable microorganisms. All three locations displayed very similar taxonomic profiles, with the genus Rubrobacter and the families Xenoco…
Identification of Synaptic Integration Mode in CA3 Pyramidal Neuron Model
2019
International audience; A morphologically realistic and anisotropic model of CA3 pyramidal neuron was developed to determine the synaptic integration modes the neuron is able to perform. Linearity and nonlinearity were identified in different synaptic locations with varying active mechanisms such as the presence of ionic channels in the dendritic arbor and the types of receptors in the synapse. Quantification of synaptic integration was performed using paired-pulse stimulation protocol and subthreshold input/output (sI/O) transformation. Results show that the mode of synaptic integration is location-dependent while the linearity or nonlinearity in the integration is mainly influenced by the…
Il sopralluogo di polizia giudiziaria. Tra latitanze legislative e prassi operative devianti
2013
L’ordinamento giuridico ci ha abituato all’accettazione dell’aforisma shakespeariano in virtù del quale “ciò che noi chiamiamo con il nome rosa, anche se lo chiamassimo con un altro nome, avrebbe pur sempre lo stesso dolce profumo”. Si tratta di un principio che, applicato al meno poetico mondo del diritto, esalta la sostanza di un atto, il suo contenuto giuridico, ponendo sul piano dell’irrilevanza la veste formale del nomen iuris. A volte, però, l’impiego disinvolto di un termine può celare insidie che incidono irrimediabilmente sulle garanzie difensive dell’individuo. Il riferimento è al c.d. sopralluogo di polizia giudiziaria nel quale convivono incertezze normative e prassi operative d…
Microwave-assisted extraction of pyrethroid insecticides from semi permeable membrane devices (SPMDs) used to indoor air monitoring
2006
Abstract A rapid and environmentally friendly methodology was developed for the extraction of pyrethroid insecticides from semi permeable membrane devices (SPMDs), in which they were preconcentrated in gas phase. The method was based on gas chromatography mass–mass spectrometry determination after a microwave-assisted extraction, in front of the widely employed dialysis method. SPMDs were extracted twice with 30 mL hexane:acetone, irradiated with 250 W power output, until 90 °C in 10 min, this temperature being held for another 10 min. Clean-up of the extracts was performed by acetonitrile–hexane partitioning and solid-phase extraction (SPE) with a combined cartridge of 2 g basic-alumina, d…
Lo ZEN e l'arte della narrazione dei luoghi
2011
This paper aims at analysing a very well-known Italian neighbourhood, which is located in Palermo and called Zen. This neighbourhood has often been described as a clear example of the worst and most disgraced urban landscapes in Italy, as mass media and local stakeholders shaped its image for their own uses. Through a series of interviews, on-the-spot inspections and the use of other qualitative methodologies, the final goal of this paper is to subvert traditional representations of this place and enforce a plural way of describing it, using research techniques that might position the researcher and his or her own description inside a larger framework. Would geographers, social scientists a…
