Pheromone-induced odor learning modifies Fos expression in the newborn rabbit brain.

2013

Research report; International audience; Associative learning contributes crucially to adjust the behavior of neonates to the permanently changing environment. In the European rabbit, the mammary pheromone (MP) excreted in milk triggers sucking behavior in newborns, and additionally promotes very rapid learning of initially neutral odor cues. Such stimuli become then as active as the MP itself to elicit the orocephalic motor responses involved in suckling. In this context, the rabbit is an interesting model to address the question of brain circuits early engaged by learning and memory. Here, we evaluated the brain activation (olfactory bulb and central regions) induced in 4-day-old pups by …

Sharpness of the differentiability almost everywhere and capacitary estimates for Sobolev mappings

2017

We give sharp conformal conditions for the dfferentiability in the Sobolev space W1, n-1 loc (Ω,Rn). Furthermore, we show that the space W1, n-1 loc (Ω,Rn) can be considered as the borderline space for some capacitary inequalities. peerReviewed

Dal CAD al GIS: il trasferimento di informazioni cartografiche

2005

L’utilizzo della cartografia nei GIS impone una riflessione sulle caratteristiche che essa deve possedere al fine di consentire le elaborazioni tipiche di questi sistemi e rende necessario verificare quali siano le informazioni che rimangono associate agli oggetti della classe al momento del caricamento dei dati, in formato DXF, all’interno di software GIS. Negli ultimi anni a livello internazionale sono state fissate norme tendenti a individuare linee guida per la definizione della struttura del contenuto semantico della cartografia numerica, delle caratteristiche geometriche e delle relazioni topologiche dell’informazione geografica.

Cartographic Language in Thematic Maps

2015

This paper analyzes the effectiveness of maps as transmitters of information. To this end, some basic concepts concerning the properties of cartographic language are examined, with the aim of helping the reader design maps conveying geographic information as clearly as possible. It also describes the innate taste of geographers for maps –how these attract and stimulate them. Then it deals with the emergence of the Internet and the new technologies allowing massive map visualization, downloading and production. The paper is illustrated with ten thematic maps, in which visual variables (i.e. size, shape, value, color, orientation and texture) are combined with the different marks (points, lin…

(Un)exhausted Cartographies. Re-living the visuality, aesthetics and politics in contemporary mapping theories and practices

This thesis is concerned with examining the life and deadliness of the map trope in contemporary Human Geography and the various ways maps and mapping have been re-theorized over the past twenty five years. Arguing that there is presently a feeling of exhaustion and disinterest amongst many human geographers in the use of maps given a shift to postmodern and poststructural approaches that decentre maps and mistrust their supposed objectivity, their representational qualities, and use by institutions to justify certain political actions, it tries to relive the attention in the ubiquity and flourishing of contemporary mapping practices by promoting a re-worked post-representational perspectiv…

Peptide mapping by reversed-phase high-performance liquid chromatography employing silica rod monoliths.

2003

In this paper, a general procedure is described for the generation of peptide maps of proteins with monolithic silica-based columns. The peptide fragments were obtained by tryptic digestion of various cytochrome c species with purification of the tryptic fragments achieved by reversed-phase high-performance liquid chromatographic methods. Peak assignment of the various peptides was based on evaluation of the biophysical properties of the individual peptides and via mass spectrometric identification. The performance of several different monolithic sorbents prepared as columns of identical cross-sectional dimensions were investigated as part of these peptide mapping studies and the data evalu…

Sediment delivery processes and the spatial distribution of caesium-137 in a small Sicilian basin

1998

The sediment delivery processes occurring in a small Sicilian basin are modelled using the spatially distributed SEDD model recently proposed by Ferro and Minacapilli. The model is applied by using soil data (grain-size distribution, organic matter content, etc.) of 129 samples uniformly distributed over the study area and compiling the available information (topographic map, soil data, etc.) into a Geographical Information System. Finally, the predictive capability of the distributed sediment delivery approach is tested experimentally using the caesium-137 measurement technique. The comparison between calculated sediment yield and the corresponding measured caesium-137 loss is used to vali…

Differential function of the phosphoglucomutase isozymes PGM1 and PGM2

1979

A total of 13 metabolites thought to be possibly inhibitory were tested for their influence on PGM isozyme activities, each at several different concentrations. The analysis of statistical significance was based on enzyme activities obtained by densitometric measurements of starch gels. Five of the substances were found to inhibit PGM activity, three of which definitely and a further one probably led to a significantly stronger inhibition of the isozymes of the PGM2 locus than of PGM1 isozymes. They are (1) fructose-1,6-diphosphate, (2) adenosine triphosphate, (3) citrate, and (4) possibly 2,3-diphosphoglycerate. Thus, PGM1 isozymes proved to function better in hard or perhaps marginal meta…

Regulatory activity of polyunsaturated fatty acids in T-cell signaling.

2009

n-3 Polyunsaturated fatty acids (PUFA) are considered to be authentic immunosuppressors and appear to exert beneficial effects with respect to certain immune-mediated diseases. In addition to promoting T-helper 1 (Th1) cell to T-helper 2 (Th2) cell effector T-cell differentiation, n-3 PUFA may also exert anti-inflammatory actions by inducing apoptosis in Th1 cells. With respect to mechanisms of action, effects range from the modulation of membrane receptors to gene transcription via perturbation of a number of second messenger cascades. In this review, the putative targets of anti-inflammatory n-3 PUFA, activated during early and late events of T-cell activation will be discussed. Studies h…
