Lower Cretaceous tholeiitic dyke swarms from the Ponta Grossa Arch (southeast Brazil): Petrology, Sr-Nd isotopes and genetic relationships with the P…
1990
The Lower Cretaceous dykes of the Ponta Grossa Arch, the most important dyke swarms in Brazil, are associated with the flood basalts and rare acid flows of the northern Parana basin. The Ponta Grossa (PG) dykes are formed by two-pyroxene tholeiites and rare acid rocks. The basaltic dykes may be distinguished into two main groups: a dominant, high-TiO2 (> 2 wt.%; HTi) group and a subordinate, low-TiO2 (< 2 wt.%; LTi) group, characterized, for similar MgO content, by high and low incompatible-element contents, respectively. Most PG dykes do not show chemical and isotope evidence supporting important crustal contamination. PG dykes with (87Sr86Sr)0 < 0.7060 plot in the mantle array (ϵSr ≈ + 17…
Ladri di luce. Leonardo Sciascia e Piero Guccione tra bellezza e verità
2023
The unpublished correspondence between Leonardo Sciascia and Piero Guccione from 1975 to 1989 shows the profound charge of humanity that innervates the friendship between these two great Enlightenment leaders "upside down". A "correspondence of amorous senses", despite the inevitable ideological differences, which the letters reproduced here for the first time and the original contributions of the volume give us back, under the banner of the binomial "beauty-truth".
Impact des modalités d'un exercice physique sur la neuroplasticité. Focus sur les sources de BDNF
2019
Physical exercise (EX) is recognized as the most potent non-pharmacological strategy to positively enhance brain health. From Human and animal studies there is a consensus to involve brain-derived neurotrophic factor (BDNF), a neurotrophin strongly expressed in response to EX and implicated in neuroplasticity mechanisms. Mainly expressed by neurons, BDNF is also expressed by endothelial and muscle cells. Largely sought during a physical effort, endothelium and skeletal muscle could be involved in positive effects induced by EX. Although there is a real consensus about BDNF and cerebral effect of EX, the typology of the better regimen of EX to enhance cerebral plasticity is not known. In thi…
Short-term e-cigarette vapour exposure causes vascular oxidative stress and dysfunction: evidence for a close connection to brain damage and a key ro…
2019
Abstract Aims Electronic (e)-cigarettes have been marketed as a ‘healthy’ alternative to traditional combustible cigarettes and as an effective method of smoking cessation. There are, however, a paucity of data to support these claims. In fact, e-cigarettes are implicated in endothelial dysfunction and oxidative stress in the vasculature and the lungs. The mechanisms underlying these side effects remain unclear. Here, we investigated the effects of e-cigarette vapour on vascular function in smokers and experimental animals to determine the underlying mechanisms. Methods and results Acute e-cigarette smoking produced a marked impairment of endothelial function in chronic smokers determined b…
Polatuzumab vedotin as a salvage and bridging treatment in relapsed or refractory large B-cell lymphomas
2021
The antibody-drug conjugate polatuzumab vedotin (pola) has recently been approved in combination with bendamustine and rituximab (pola-BR) for patients with refractory or relapsed (r/r) large B-cell lymphoma (LBCL). To investigate the efficacy of pola-BR in a real-world setting, we retrospectively analyzed 105 patients with LBCL who were treated in 26 German centers under the national compassionate use program. Fifty-four patients received pola as a salvage treatment and 51 patients were treated with pola with the intention to bridge to chimeric antigen receptor (CAR) T-cell therapy (n = 41) or allogeneic hematopoietic cell transplantation (n = 10). Notably, patients in the salvage and brid…
Laura Bianchini. Dall'associazionismo cattolico all'impegno in politica
2022
Laura Bianchini (1903 - 1983) was among those women who first crossed the threshold of the "palaces" of politics. She was a member of the National Council, then of the Constituent Assembly and deputy of the Chamber during the first legislature. Teacher and publicist, he knew how to combine spirituality and political and civil commitment. Militant in the Resistance, exponent of the Catholic women's movement, representative of the left current of the Christian Democrats. His spiritual formation and his cultural setting of a personalist and community type is due not only to his militancy within the FUCI and the Graduate Movement, but also to the Catholic environment in Brescia and to the influ…

Le valutazioni di bilancio nella prospettiva della tradizione giuridica e dottrinale italiana
2018
Il capitolo si inserisce quale introduzione storiografica al tema oggetto di una monografia open source patrocinata dalla Sidrea (Società Italiana di Ragioneria ed Economia Aziendale). Detta monografia è il frutto di una ricerca collettanea sulla riforma del bilancio civilistico ex DPR 139/2015. I singoli contributi della stessa riguardano infatti le singole aree del bilancio. Rispetto a questa complessiva ricerca della società accademica di settore, il saggio/capitolo in oggetto, a natura esplicitamente introduttiva, intende mostrare come la disciplina giuridica sia sempre stata influenzata da un dibattito dottrinale a monte di tipo economico-aziendale, questo in Italia particolarmente ric…
Isolation of the Endothelin B Receptor from Bovine Lung Structure, Signal Sequence, and Binding Site
1995
Bovine lung endothelin-B receptor has been isolated in good yield with a new procedure involving the use of endothelin-1 coupled to iminobiotin with a long spacer and avidin-agarose affinity chromatography. Contrary to previous reports, evidence has been obtained that the native form of this receptor corresponds to the full-length transcript expected on the basis of cDNA clones. The binding of endothelin to a variety of shortened fragments of the full receptor suggests that the long N-terminal sequence of this receptor has very little influence on the binding of endothelin and that the main determinants of the endothelin binding site might be constituted by residues in the sixth, and possib…
MANOTA: a promising bifunctional chelating agent for copper-64 immunoPET
2017
International audience; Improved bifunctional chelating agents (BFC) are required for copper-64 radiolabelling of monoclonal antibodies (mAbs) under mild conditions to yield stable, target-specific imaging agents. Four different bifunctional chelating agents (BFC) were evaluated for Fab (Fragment antigen binding) conjugation and radiolabelling with copper-64. Two DOTA- (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) and two NOTA- (1,4,7-triazacyclononane-1,4,7-triacetic acid) derivatives bearing a p-benzyl-isothiocyanate group were conjugated to Fab-trastuzumab - which targets the HER2/neu receptor - and the average number of chelators attached ranged from 2.4 to 4.3 macrocycles …
