Il Mezzogiorno di Bandi e Abba tra esotismi e stigmatizzazioni
2014
Ad eccezione di taccuini, articoli di giornale o lettere, la maggior parte dei memorialisti garibaldini si dedicò alla scrittura solo alcuni anni dopo le imprese della Spedizione dei Mille. Considerando la provenienza non meridionale della maggior parte di loro, è interessante vedere come il Sud sia stato per lo più caratterizzato in senso esotico e memoriale: luogo misterioso e fonte di stereotipi, cullato nella memoria e testualizzato attraverso una scrittura che esalta il dato leggendario.
High resolution analysis and differential condensation in RBA-banded human chromosomes.
1981
Human prophase, premetaphase, and mid-metaphase chromosomes are prepared and analyzed using the thymidine cell synchronization technique and R-banding patterns (RBA). Haploid sets with 700–1000 bands can be demonstrated. Sequences of chromosomes of different degrees of condensation are helpful for a better understanding and classification of regions of extended chromosomes. A considerable variation in the condensation of parts of homologous chromosomes is reflected in the variability of the arm ratio. This differential condensation of chromosomes is entirely effected by variation of the degree of condensation in AT rich interbands and can be attributed to the degree of labeling by BrdU.
El dominio de Valencia sobre el vizcondado de Chelva (1395-1408): sobre la libertad de la ciudad y la libertad del reino
2020
espanolLa delegacion de competencias soberanas de la monarquia mediante la concesion de fueros y privilegios sostuvo el ejercicio de las libertades urbanas, las cuales de forma ineludible habian de ser juradas por el rey para tomar posesion del trono y ser reconocido por los subditos en la Corona de Aragon. El analisis de un caso concreto en el ejercicio de esas libertades, como las prerrogativas de la ciudad de Valencia sobre su reino, aplicadas sobre el vizcondado de Chelva, tuvo un gran impacto politico, social y economico, muy alejado de la carga emocional implicita a los movimientos sociales medievales, y en especial de aquellos que pretendian conseguir la libertad mediante reivindicac…
Time synchronization enhancements in wireless networks with ultra wide band communications
2022
The emergence of low cost Ultra Wide Band (UWB) transceivers has enabled the implementation of Wireless Sensor Networks (WSN) based on this communication technology. These networks are composed of distributed autonomous low cost nodes (also known as motes) with their own processing unit, memory and communications. Usually these nodes are power-limited and due to the poor performance and quality of their clocks, time synchronization is in the order of milliseconds and in some specific scenarios till microseconds. The integration of commercial UWB transceivers in these nodes can improve the synchronization accuracy. In particular, we focus on WSN nodes based on off-the-shelf commercial produc…

Chromosomal Localization of 18S-28S rDNA and (TTAGGG)n Sequences in Two South African Dormice of the Genus Graphiurus (Rodentia: Gliridae).
2019
Classical cytogenetics and mapping of 18S-28S rDNA and (TTAGGG)<>n sequences by fluorescence in situ hybridization (FISH) was performed on Graphiurus platyops (GPL) and Graphiurus ocularis (GOC) metaphases with the aim to characterize the genomes. In both species, inverted DAPI karyotypes showed the same diploid number, 2n = 46, and hybridization of the (TTAGGG)<>n probe revealed interstitial telomeric sequences (ITSs) at the centromeres of almost all bi-armed chromosomes. FISH with the rDNA probe localized nucleolus organizer regions (NORs), at the terminal ends of the p arms of the telocentric pairs 16 and 17 in both species and detected additional signals on GPL8 and GOC18, 1…
Detection of translocations affecting the BCL6 locus in B cell non-Hodgkin's lymphoma by interphase fluorescence in situ hybridization
2001
Structural alterations in 3q27 affecting the BCL6 locus are among the most frequent changes in B-NHL. The aim of the present study was to establish an interphase-FISH assay for the detection of all diverse BCL6 translocations in B-NHL. Two different approaches were tested, one using a PAC-clone spanning the major breakpoint region (MBR) of BCL6 (span-assay), and another using two BAC clones flanking the MBR (flank-assay). Interphase FISH with the span-assay detected the various BCL6 translocations in seven B-NHL cell lines. The dual-color flank-assay was evaluated in two laboratories independently: in normal controls, the cutoff level for false-positive signals was 2.6%, whereas the cutoff …
Distinct Xp11.2 breakpoints in two renal cell carcinomas exhibiting X;autosome translocations
1995
Several human renal cell carcinomas with X;autosome translocations have been reported in recent years. The t(X; I)(p11.2;q21) appears to be a specific primary anomaly, suggesting that tumors with this translocation form a distinct subgroup of RCC. Here we report two new cases, one with a t(X;10)(p11.2;q23), the other with a t(X;1)(p11.2;p34). The common breakpoint in Xp11.2 suggests that they belong to the above-mentioned subset of RCC. Using FISH in conjunction with X-specific YAC clones, we demonstrate that the two new cases exhibited distinct breakpoints within Xp11.2. (C) 1995 Wiley-Liss, Inc.
Chromosome 5 abnormalities in acute lymphoblastic leukemia
1991
Abstract We report two cases of acute lymphoblastic leukemia with involvement of chromosome 5. One of them showed a del(5)(q13q33) in a 5-year-old boy who had previously received antineoplastic chemotherapy for an L1-ALL that had been diagnosed nine months before. The other one showed a t(5;7)(q12–13;q36) together with a t(8;14)(q24;q32) and a der(1) in a 66-year-old man with an L3-ALL. Both chromosome 5 aberrations are interpreted as evolutionary events. In the first case, it was secondary to chemotherapy treatment; in the second, an evolutionary chromosome rearrangement, considering the translocation between chromosomes 8 and 14 as the primary cytogenetic event.
