Suitability of simplified milk recording methods for genetic evaluations using test-day models in dairy sheep

2008

Nowadays in dairy sheep, test-day records are collected monthly under an alternate morning/evening system. This alternate system was implemented because of the steady increase in recording cost per sheep observed in the last few decades. Furthermore, additional modifications to the testing schemes have been proposed to reduce the costs of milk recording. In dairy sheep, the cost for milk recording is indeed too high compared both with individual outputs and with other dairy species. Therefore, the purposes of the present study were: i) to compare estimated breeding values (EBVs) for milk yield using different simplified testing schemes with a test-day sire model; ii) to evaluate the effect …

Metilazione del DNA in artrite reumatoide

2005

Lo stato di metilazione del DNA genomico e del gene PTHrP è stato valutato con tecniche molecolari e citogenetiche in artrite reumatoide (AR), patologia autoimmune caratterizzata anche da alta incidenza di linfomi e da ipercalcemia per overespressione del gene PTHrP. La metilazione del DNA, infatti, ha un ruolo critico nello sviluppo delle malattie neoplastiche; il gene PTHrP avendo tre promotori uno dei quali contiene un’isola CpG è un buon candidato per la deregolazione da alterato pattern di metilazione locale. Le indagini sulla metilazione genomica, condotte su DNA estratto da sangue periferico di pazienti e di donatori e amplificato in reazioni di Methylation-Sensitive Arbitrarily Prim…

Settore BIO/18 - Geneticainstead chromosomes of controls were almost uniformly decorated by brilliant grains. Studies on methylation of PTHrP gene promoter 2 performed on five CpG island internal sites using the Methylation-Sensitive Restriction Endonuclease Multiplex (MSREM)-PCR showed that one of the sites nearest the trascription starting point is heavy methylated in a significantly high number of RA patients. Thus RA seems to be characterized by genomewide hypomethylation associated with local hypermethylation like the most part of tumors. This result raises the possibility that susceptibility to lymphomas is related to abnormal DNA methylation levels and suggests the opportunity to evaluate the DNA methylation status in RA patientin fact the demethylating therapies together with diet and life style can act towards an increase of tumor risk. Future studies using a larger number of subjects could confirm these findings.Rheumatoid Arthritis (RA) is a chronic multisystem inflammatory disease characterized by high recurrence of lymphomas as well as hypercalcemia due to PTHrP overexpression. Because of DNA methylation plays a critical role in development of neoplasias we determined in RA patients the global DNA methylation status and local methylation pattern of the CpG island of one of the three promoters of PTHrP gene utilizing molecular and cytogenetic techniques. Investigations performed on DNA from peripheral blood of patients and donors amplified by Methylation-Sensitive Arbitrarily Primed (MeS-AP)-PCR indicated that RA is strongly associated with global DNA hypomethylation. Similarly chromosomal DNA methylation pattern analysis by indirect immunofluorescence technique with anti 5-methylcitosine antibody showed all peripheral lymphocyte metaphases from RA patients with chromosomes weakly fluorescent without discrete grain

La salute delle strutture molli e dure del cavo orale è essenziale non solo per preservare le funzioni ad esse direttamente associate, ma anche per promuovere la salute generale dell’organismo. Tra le problematiche di maggiore interesse clinico a carico della cavità orale ritroviamo: i) le complicazioni post-operatorie che possono verificarsi a seguito di comuni avulsioni dentali che, se non trattate tempestivamente, possono sfociare in gravi parodontiti; ii) i fenomeni di osteonecrosi a carico di mascella e mandibola associate a trattamenti farmacologici nonché alla radioterapia; iii) il carcinoma orale a cellule squamose (OSCC) che è tra i più aggressivi tumori del collo e della testa, ca…

Can uncertainty in flood hazard estimation be reduced by using high detailed topographic data for floodplain modelling?

2011

Floods are considered the most frequent natural disaster world-wide and may have serious socio economic impacts in a community. In order to accomplish flood risk mitigation, flood risk analysis and assessment are required to provide information on current or future flood hazard and risks. Hazard and risk maps involve different data, expertise and effort, depending also on the end-users. More or less advanced deterministic approaches can be used, but intuitively probabilistic approaches seem to be more correct and suited for modelling flood inundation given typical uncertainties. Two very important matters remain open for research: the calibration of hydraulic models (oriented towards the es…

Quantifying sensitivity and uncertainty analysis of a new mathematical model for the evaluation of greenhouse gas emissions from membrane bioreactors

2015

Abstract A new mathematical model able to quantify greenhouse gas (GHG) emissions in terms of carbon dioxide (CO 2 ) and nitrous oxide (N 2 O) for a Membrane Bioreactor (MBR) is presented. The proposed mathematical model is of the Activated Sludge Model (ASM) family and takes into account simultaneously both biological and physical processes (e.g., membrane fouling). An analysis of the key factors and sources of uncertainty influencing GHG emissions is also presented. Specifically, the standardized regression coefficient, the Extended-FAST and a Monte Carlo based method are employed for assessing model factors which influence three performance indicators: effluent quality index, operational…

Automated procedures based on Market Comparison Approach. A pilot study in the city of Cosenza.

2017

The question about objective valuation is linked on the one hand to the identification of a large number of reliable sale data, on the other hand to the ability to control the critical evaluation protocol. Automating the valuation process, ensured by computerization of real estate data properly detected, provides a concrete answer to the problem of objectivity, allowing a significant control of the subjective component which characterizes the more traditional appraisals. Automatic methods traditionally proposed at international level are often set on multiple regression models, designed to build prediction functions that are valid throughout the study area, calibrating the coefficients on t…
