Colour traits in the evaluation of the ripening period of Asiago cheese
Giorgio Marchesini,Stefania Balzan,Severino Segato,Enrico Novelli
Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2009.s2.412
Abstract: The research was carried out on Asiago d’Allevo cheese samples produced in a single farm located in the Altopiano dei Sette Comuni (above 1000m a.s.l.). After 6-12-18 and 36 months of ripening, samples were analyzed for quality traits, in order to evaluate the effect of ripening on colour and gross composition. As expected crude protein and fat significantly increased through the considered period. Ripening led to a significant decrease of L*, a* and b* values. Lightness showed a negative relationship with crude protein, meanwhile a* and b* were both negatively related to fat content. Concerning L*, the trend could be explained by water loss and N-soluble compounds concentration, which could alter protein matrix. a* and b* reduction was probably related to degradation processes such as lipolysis, which seemed to be extensive in hard and long ripened cheese. Ripening affected significantly the light reflectance at all λ with green cheese having the higher values.
Polar Electrophoresis: Shape of Two-Dimensional Maps Is as Important as Size
Renato Millioni, Rita Polati, Michele Menini, Lucia Puricelli, Manuela Miuzzo, Paolo Tessari, Enrico Novelli, Pier Giorgio Righetti, Daniela Cecconi
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0030911
Abstract: The performance of two-dimensional electrophoresis in conventional gels in Cartesian coordinates (2-DE) vs. polar coordinates (2-PE) is here evaluated. Although 2-DE is performed in much longer Immobiline gels in the first dimension (17 cm) vs. barely 7-cm in 2-PE, an equivalent resolving power is found. Moreover, due to the possibility of running up to seven Immobiline strips in the radial gel format, the reproducibility of spot position is seen to be higher, this resulting in a 20% higher matching efficiency. As an extra bonus, strings of “isobaric” spots (i.e. polypeptides of identical mass with different pI values) are more resolved in the radial gel format, especially in the 10 to 30 kDa region, where the gel area fans out leaving extra space for spot resolution. In conclusion, this novel gel format in the second dimension of 2D gels is seen as an important improvement of this technique, still one of the most popular in proteome analysis.
Overexpression of CUGBP1 in Skeletal Muscle from Adult Classic Myotonic Dystrophy Type 1 but Not from Myotonic Dystrophy Type 2

Abstract: Myotonic dystrophy type 1 (DM1) and type 2 (DM2) are progressive multisystemic disorders caused by similar mutations at two different genetic loci. The common key feature of DM pathogenesis is nuclear accumulation of mutant RNA which causes aberrant alternative splicing of specific pre-mRNAs by altering the functions of two RNA binding proteins, MBNL1 and CUGBP1. However, DM1 and DM2 show disease-specific features that make them clearly separate diseases suggesting that other cellular and molecular pathways may be involved. In this study we have analysed the histopathological, and biomolecular features of skeletal muscle biopsies from DM1 and DM2 patients in relation to presenting phenotypes to better define the molecular pathogenesis. Particularly, the expression of CUGBP1 protein has been examined to clarify if this factor may act as modifier of disease-specific manifestations in DM. The results indicate that the splicing and muscle pathological alterations observed are related to the clinical phenotype both in DM1 and in DM2 and that CUGBP1 seems to play a role in classic DM1 but not in DM2. In conclusion, our results indicate that multisystemic disease spectrum of DM pathologies may not be explained only by spliceopathy thus confirming that the molecular pathomechanism of DM is more complex than that actually suggested.

Guerra en las Aulas: violencia política en contra del sector de la educación en Colombia
Mario Novelli
El Agora USB , 2009,
Abstract: his article shows the research results about the political violence against teachers, not only does it introduce figures but also it goes into detail about the nature and the dynamics of the manner how teachers are affected by the political violence in Colombia. As well, it presents the different strategies of resistance that trade unionists in the educational sector and their allies, have developed throughout the years, in order to defend their human rights. The result of this research shows the conclusions about the current situation of the Colombian teachers and poses some suggestions, addressed to the international educational community, trade unions, human rights movement, on how to help our colleagues in Colombia.
Extremal rays of non-integral $L$-length
Carla Novelli
Mathematics , 2011,
Abstract: Let $X$ be a smooth complex projective variety and let $L$ be a line bundle on it. We describe the structure of the pre-polarized manifold $(X,L)$ for non integral values of the invariant $\tau_L(R):=-K_X\cdot\Gamma/(L \cdot \Gamma)$, where $\Gamma$ is a minimal curve of an extremal ray $R:=\mathbb R_+[\Gamma]$ on $X$ such that $L \cdot R>0$.
On Fano manifolds with an unsplit dominating family of rational curves
Carla Novelli
Mathematics , 2011,
Abstract: We study Fano manifolds $X$ admitting an unsplit dominating family of rational curves and we prove that the Generalized Mukai Conjecture holds if $X$ has pseudoindex $i_X = (\dim X)/3$ or dimension $\dim X=6$. We also show that this conjecture is true for all Fano manifolds with $i_X > (\dim X)/3$.
Geostatistical Modeling of Uncertainty for the Risk Analysis of a Contaminated Site  [PDF]
Enrico Guastaldi
Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.38066
Abstract: This work is a study of multivariate simulations of pollutants to assess the sampling uncertainty for the risk analysis of a contaminated site. The study started from data collected for a remediation project of a steel- works in northern Italy. The soil samples were taken from boreholes excavated a few years ago and analyzed by a chemical laboratory. The data set comprises concentrations of several pollutants, from which a subset of ten organic and inorganic compounds were selected. The first part of study is a univariate and bivariate sta- tistical analysis of the data. All data were spatially analyzed and transformed to the Gaussian space so as to reduce the effects of extreme high values due to contaminant hot spots and the requirements of Gaussian simulation procedures. The variography analysis quantified spatial correlation and cross-correlations, which led to a hypothesized linear model of coregionalization for all variables. Geostatistical simulation methods were applied to assess the uncertainty. Two types of simulations were performed: correlation correction of univariate sequential Gaussian simulations (SGS), and sequential Gaussian co-simulations (SGCOS). The outputs from the correlation correction simulations and SGCOS were analyzed and grade-tonnage curves were produced to assess basic environmental risk.
