Cadherin 23 is a component of the transient lateral links in the developing hair bundles of cochlear sensory cells
2005
AbstractCadherin 23 is required for normal development of the sensory hair bundle, and recent evidence suggests it is a component of the tip links, filamentous structures thought to gate the hair cells' mechano-electrical transducer channels. Antibodies against unique peptide epitopes were used to study the properties of cadherin 23 and its spatio-temporal expression patterns in developing cochlear hair cells. In the rat, intra- and extracellular domain epitopes are readily detected in the developing hair bundle between E18 and P5, and become progressively restricted to the distal tip of the hair bundle. From P13 onwards, these epitopes are no longer detected in hair bundles, but immunoreac…

CONTROLLO GLICOMETABOLICO E ABITUDINI ALIMENTARI IN ADOLESCENTI CON DIABETE MELLITO TIPO 1
2011
Background: Gli studi che hanno valutato le abitudini alimentari dei bambini e adolescenti con diabete, hanno riportato una percentuale di assunzione di carboidrati più bassa di quella minima raccomandata spesso associata ad un maggiore consumo di grassi e ad una ridotta assunzione di fibre . Alcuni studi che hanno valutato il rapporto tra composizione della dieta e controllo glicometabolico in soggetti con diabete tipo 1, hanno evidenziato che una dieta ricca di grassi e povera di fibre è associata ad un peggior controllo glicometabolico. Obiettivo: Valutare in adolescenti affetti da diabete mellito tipo 1, con diverso grado di controllo metabolico, la frequenza di consumo settimanale dei …
Diffusion coefficient of PVA Fricke gel dosimeters
2015
Fricke gel dosimeters based on various matrix has been studied for a long time as 3D dosimetric system for radiotherapy. Selfoxidation and loss of spatial resolution due to diffusion have been the main issues that have impaired the affirmation of this technique so far. As part of an Italian nation-wide research program, we were interested in develop new gel formulations that are simple, reproducible and non toxic. We studied the one dimensional diffusion coefficient of Fe3+ ions inside Fricke gel dosimeters based on a matrix of PVA cross-linked with a di-aldehyde. With a spectrophotometer equipped with a moving tray we were able to collect absorbance measurements at different positions of t…

Mutational Events in Cefotaximase Extended-Spectrum β-Lactamases of the CTX-M-1 Cluster Involved in Ceftazidime Resistance
2008
ABSTRACT CTX-M β-lactamases, which show a high cefotaxime hydrolytic activity, constitute the most prevalent extended-spectrum β-lactamase (ESBL) type found among clinical isolates. The recent explosive diversification of CTX-M enzymes seems to have taken place due to the appearance of more efficient enzymes which are capable of hydrolyzing both cefotaxime and ceftazidime, especially among the CTX-M-1 cluster. A combined strategy of in vitro stepwise evolution experiments using bla CTX-M-1 , bla CTX-M-3 , and bla CTX-M-10 genes and site-directed mutagenesis has been used to evaluate the role of ceftazidime and other β-lactam antibiotics in triggering the diversity found among enzymes belong…
Characterization and phylogenetic analysis of a cDNA encoding the Fes/FER related, non-receptor protein-tyrosine kinase in the marine sponge Sycon ra…
1998
Abstract In search of ancient versions of phylogenetically conserved genes/proteins, which are typical for multicellular animals, we have decided to analyse marine sponges (Porifera), the most ancient and most primitive metazoan organisms. We report here the complete nucleotide sequence of Sycon raphanus cDNA coding for a 879 aa long protein (100 kDa), which displays high overall similarity in primary structure and organization of domains with non-receptor tyrosine kinases (TKs) from the Fes/FER family. The encoded protein, which we named Fes/FER_SR, has a highly conserved, 260 aa long tyrosine kinase domain at the C-terminus. Amino-terminal to the catalytic domain is an 85 aa long SH2 doma…
Machine learning at the interface of structural health monitoring and non-destructive evaluation
2020
While both non-destructive evaluation (NDE) and structural health monitoring (SHM) share the objective of damage detection and identification in structures, they are distinct in many respects. This paper will discuss the differences and commonalities and consider ultrasonic/guided-wave inspection as a technology at the interface of the two methodologies. It will discuss how data-based/machine learning analysis provides a powerful approach to ultrasonic NDE/SHM in terms of the available algorithms, and more generally, how different techniques can accommodate the very substantial quantities of data that are provided by modern monitoring campaigns. Several machine learning methods will be illu…
