description: Strong nonlocality based on local distinguishability is a stronger form of quantum nonlocality recently introduced in multipartite quantum systems: an orthogonal set of multipartite quantum states is said to be of strong nonlocality if it is locally irreducible for every bipartition of the subsystems. Most of the known results are limited to sets with product states. Shi et al. presented the first result of strongly nonlocal entangled sets in [Phys. Rev. A 102, 042202 (2020)] and there they questioned the existence of strongly nonlocal set with genuine entanglement. In this work, we relate the strong nonlocality of some speical set of genuine entanglement to the connectivities of some graphs. Using this relation, we successfully construct sets of genuinely entangled states with strong nonlocality. As a consequence, our constructions give a negative answer to Shi et al.'s question, which also provide another answer to the open problem raised by Halder et al. [Phys. Rev. Lett. 122, 040403 (2019)]. This work associates a physical quantity named strong nonlocality with a mathematical quantity called graph connectivity.

description: In the borders of the dead zones of protoplanetary disks, the inflow of gas produces a local density maximum that triggers the Rossby wave instability. The vortices that form are efficient in trapping solids. We aim to assess the possibility of gravitational collapse of the solids within the Rossby vortices. We perform global simulations of the dynamics of gas and solids in a low mass non-magnetized self-gravitating thin protoplanetary disk with the Pencil code. We use multiple particle species of radius 1, 10, 30, and 100 cm. The dead zone is modeled as a region of low viscosity. The Rossby vortices excited in the edges of the dead zone are very efficient particle traps. Within 5 orbits after their appearance, the solids achieve critical density and undergo gravitational collapse into Mars sized objects. The velocity dispersions are of the order of 10 m/s for newly formed embryos, later lowering to less than 1 m/s by drag force cooling. After 200 orbits, 38 gravitationally bound embryos were formed inside the vortices, half of them being more massive than Mars. The embryos are composed primarily of same-sized particles. We conclude that the presence of a dead zone naturally gives rise to a population of protoplanetary cores in the mass range of 0.1-0.6 Earth masses, on very short timescales.

description: The analyses of the LHCb data on X(2900) in the D^- K^+ spectrum are performed. Both dynamically generated and explicitly introduced X_1(2900) are considered. The results show that both these two approaches support the interpretation of X_1(2900) as a bar{D}_1 K molecular state, with J^{P}=1^- and an iso-singlet interpretation is much more favorable. The effect of triangle singularity on the production of X_1(2900) is also discussed, and it is found that it cannot be interpreted as a pure triangle cusp.

The Alzheimer’s Amyloid precursor protein APP and the adaptor protein Fe65: their role in the cellular response to DNA damage
Creators: name: Stante, Maria
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: Fe65 interacts with the cytosolic domain of the Alzheimer’s amyloid precursor protein (APP). The functions of the Fe65 and of the Fe65/APP complex are still unknown. To address this point we generated Fe65 knock out mice. These mice do not show any obvious phenotype, however, when fibroblasts (MEFs), isolated form Fe65 KO embryos, were exposed to low doses of DNA damaging agents, such as etoposide or H2O2, an increased sensitivity to genotoxic stress, compared to wild type animals, clearly emerged. Accordingly, brain extracts from Fe65 KO mice, exposed to non-lethal doses of ionizing radiations, showed high levels of γ-H2AX and p53, thus demonstrating a higher sensitivity to X-rays than wild type mice. Nuclear Fe65 is necessary to rescue the observed phenotype and, few minutes after the exposure of MEFs to DNA damaging agents, Fe65 undergoes phosphorylation in the nucleus. With a similar timing, the proteolytic processing of APP is rapidly affected by the genotoxic stress: in fact, the cleavage of the APP C-terminal fragments by γ-secretase is induced soon after the exposure of cells to etoposide, in a Fe65-dependent manner. These results demonstrate that Fe65 plays an essential role in the response of the cells to DNA damage. Moreover we found that Fe65 is a chromatin bound protein that determines the degree of chromatin condensation both in basal and under genotoxic stress conditions. Fe65 association with chromatin is required during DNA damage repair. Indeed a known partner of Fe65 is the histone acetyltransferase Tip60. Considering the crucial role of Tip60 in DNA repair, we explored the hypothesis that the phenotype of Fe65 null cells was dependent on its interaction with Tip60. We demonstrated that Fe65 knockdown impaired recruitment of Tip60-TRRAP complex to DNA double strand breaks and decreased histone H4 acetylation. Accordingly, the efficiency of DNA repair was decreased upon Fe65 suppression. To explore whether APP has a role in this mechanism, we analyzed a Fe65 mutant unable to bind to APP. This mutant failed to rescue the phenotypes of Fe65 null cells; furthermore, APP/APLP2 suppression results in the impairment of recruitment of Tip60-TRRAP complex to DNA double strand breaks, decreased histone H4 acetylation and repair efficiency. On these bases, we propose that Fe65 and its interaction with APP play an important role in the response to DNA damage by assisting the recruitment of Tip60-TRRAP to DNA damage sites.
Biological function of Cl 2 gene and it’s role in thyroid cancer
Creators: name: Ferraro, Angelo
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2011

description: Here I report data to support a tumor suppressor role of the Cl 2 gene. Indeed, I detected a drastic reduction, of Cl 2 gene expression in almost all thyroid carcinomas analyzed, with respect to normal thyroid, with the lowest expression levels observed in the follicular variants of papillary carcinomas. Loss of heterozygosity and CpG hypermethylation at the second exon likely accounts for Cl 2 downregulation in thyroid carcinomas. A drastic reduction in Cl 2  expression, with respect to normal counterpart tissues, was also observed in breast, colon and ovarian carcinomas. The restoration of Cl 2  expression in two human thyroid anaplastic carcinoma cell lines leads to the suppression of the malignant phenotype associated with a higher susceptibility to apoptosis.
The development of thyroid adenomas and ovarian carcinomas in Cl   knock-out mice validates the tumor suppressor role of Cl 2  gene. Finally, transgenic mice for RET/PTC1 oncogene crossed with the Cl 2  knock-out mice developed much more aggressive thyroid carcinomas compared with those observed in the single mutant RET/PTC 1 mice.
Therefore, these results taken together indicate Cl 2  as a putative tumor suppressor gene in the process of human thyroid carcinogenesis.
Electronic and optical properties of silicon nanocrystals:
a Tight Binding study
Creators: name: Trani, Fabio
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2005

description: From the theoretical point of view, the silicon nanocrystal physics still today
is not a completely clear subject. While the quantum confinement effect has
been recognized as the major cause of the photoluminescence, many doubts
remain on the way in which the phenomenon takes place in real nanocrystals.
This thesis is the result of a deep work in the understanding of the optical
properties of silicon nanocrystals. A Tight Binding method has been used for
studing the energy levels and the dielectric properties of spherical and ellipsoidal
silicon nanocrystals. The method is very efficient, allowing the study
of structures with more than 10000 atoms, and being able to reproduce with
a great accuracy the Bulk Silicon dielectric function. The comparison with
the experimental results shows that for Si nanocrystals the method works
well, both for the energy gap and the absorption spectra prediction. The
optical gap, the imaginary part of the dielectric function, the static dielectric
function, and the radiative electron-hole recombination times have been
calculated for a set of silicon spheres, on increasing their size. An interesting
feature is the existence of an energy gap between the energy of the first
transition and the threshold of the absorption cross section. This is an indication
that the electronic features of the bulk silicon are always reflected
into the silicon nanocrystal physics. A very nice confirmation of this trend is
the k-space projection of the nanocrystal states, which gives a fair explanation
of this phenomenon. Finally, the shape effects on the optical properties
are shown. Several sets of ellipsoidal nanocrystals, with different sizes and
shapes, have been analyzed, and the effects of the geometrical anisotropy on
the polarization of the dielectric tensor is discussed.
Peno-vulvoscopia digitale: una nuova metodica di analisi biofisica nella gestione dell'ambulatorio di dermatologia genitale
Creators: name: Del Sorbo, Antonio
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: La peno-vulvoscopia è una metodica diagnostica non invasiva che permette di valutare microscopicamente alcuni pattern morfologici che si possono osservare in corso di fenomeni fisiologici o patologici della cute e delle mucose dell’area genitale. Dai dati provenienti della letteratura internazionale prodotta negli ultimi anni, emerge la necessità di osservare, descrivere e memorizzare su piattaforme digitali le immagini provenienti dagli ambulatori di dermatologia genitale, con lo scopo di poter disporre in futuro di archivi di elementi morfologici il più possibile obiettivi e riproducibili. Allo stato attuale la tecnica si prefigge soltanto scopi sperimentali, in quanto tranne in rari casi, viene ancora oggi poco utilizzata dal dermatologo pratico ai fini diagnostici. I pattern peno-vulvoscopici infatti, non sono ancora del tutto standardizzati, dato il recente interesse ad una metodica strumentale e la necessità di personale addestrato nell’analisi vettoriale delle immagini digitali, oltre che di strumenti tecnologicamente via via più avanzati. La recente introduzione di sistemi digitali che consentono l’acquisizione e le analisi delle immagini e l’applicazione di programmi di intelligenza artificiale (reti neurali) per la diagnosi automatica, sta riscontrando un crescente successo in molte aree della dermatologia digitale per immagini (Videodermatoscopia ad epiluminescenza delle lesioni melanocitarie, Tricogramma con videoscansione, Videocapillaroscopia) grazie all’enorme numero di immagini osservate, archiviate e standardizzate in questi ultimi anni. Lo scopo del nostro studio è stato quello di descrivere i pattern morfologici ottenuti in peno - vulvoscopia digitale, osservabili in situazioni fisiologiche (papule perlacee, grani di Fordyce, etc) o patologiche (verruche genitali, mollusco contagioso, infezioni erpetiche, etc) in circa 1000 pazienti osservati dal 2002 al 2005. Obiettivo futuro del presente lavoro è quello di poter scambiare in tempo reale, attraverso la rete telematica (Intranet, Internet a banda larga, Rete Campana di Dermatologia Genitale, Teledermatologia), un  numero di immagini statisticamente significativo, con lo scopo di poter un giorno razionalizzare almeno in parte, il prezioso contenuto informativo delle immagini ottenute con tale metodica.

We consider the set of parameters for which every orbit recurs to the boundary between half-planes. These parameters consist of algebraic curves, determined by the symbolic dynamics of the itinerary that connects boundary points. We study the algebraic and geometrical properties of these curves, in relation with such a symbolic dynamics.

description: Previous studies have shown that the glycoproteins containing the fucose moiety are involved in neuronal communication phenomena such as long-term potentiation and memory formation. These results imply that fucose containing glycoproteins might play an important role in learning and memory. To understand the role of fucose in neuronal communication, and the mechanisms by which fucose may be involved in information storage, the identification of fucosylproteins is essential. This report describes the identification and characterization of fucosylproteins in the brain, which will provide new insights into the role of the fucose involved molecular interactions.
Trattamento delle neoplasie epatiche con termoablazione: valutazione ecografica intra-operatoria

Year: 2006

description: Le neoplasie epatiche primitive e secondarie hanno una rilevante importanza sociale per l’incidenza, le difficoltà di trattamento e la prognosi infausta nelle forme più avanzate.
Negli ultimi anni come in tutti i settori della medicina anche in chirurgia epatica si è assistito ad un sensibile progresso tecnologico che ha modificato l’approccio del chirurgo. In questo settore si è assistito ad un sensibile miglioramento delle metodiche di imaging pre-operatorie ed intra-operatorie, allo sviluppo della chirurgia laparoscopica ed all’introduzione di alcune tecniche complementari o alternative alla chirurgia ( RF, alcolizzazione e altre ), che hanno ampliato il numero di pazienti trattabili e migliorato i risultati oncologici.
Scopo dello studio presente è stato quello di valutare l’impatto di queste tecnologie sul comportamento chirurgico ed in particolare come l’associazione  tra  ecografia intra-operatoria e RF possa ottimizzare l’applicazione di questa recente metodica.
Si sono esaminati i principi fisici e le possibilità di applicazione clinica  attuali della termoablazione (ARF). Si sono valutate inoltre le informazioni fornite dall’ecografia intra-operatoria  (EIO) in corso di laparoscopia e laparotomia. L’EIO facilita l’operatore nel documentare le lesioni e effettuare resezioni “ecoguidate”, valutando i rapporti topografici delle lesioni con vasi e dotti biliari principali.
In tal senso si inserisce anche l’applicazione dell’EIO in sinergia con l’ARF. L’ausilio delle informazioni EIO in corso di ARF testimoniano in tempo reale la corretta esecuzione e l’efficacia di questo trattamento.
Prescindendo dalla valutazione oncologica dell’ARF,i nostri dati (relativi a 16 pazienti trattati negli ultimi 2 anni) anche se numericamente contenuti, sono incoraggianti e ci spingono a proseguire in tal senso, confermando quanto riportato in letteratura relativamente alla sicurezza, alla facile esecuzione ed alla necessità di utilizzare sempre l’ecografia accanto allo strumentario per ARF. Ulteriori progressi sono auspicabili con il perfezionamento dell’ARF e con l’uso routinario dei mezzi di contrasto ultrasonografici che renderanno questa metodica ancora più sensibile ed affidabile.
Observation of long-range carrier diffusion in InGaN quantum wells, and implications from fundamentals to devices

description: Photoluminescence measurements on high-quality InGaN quantum wells reveal that carriers diffuse laterally to long distances at room temperature, up to tens of microns. This behavior, which shows a pronounced dependence on the excitation density, contrasts with the common expectation of a short diffusion length. The data is well explained by a diffusion model taking into account the full carrier recombination dynamics, obtained from time-resolved measurements. These observations have important implications for understanding the high efficiency of III-nitride emitters, but also to properly interpret photoluminescence experiments and to design efficient small-scale devices.
Hopping conductivity in lightly doped semiconductors
Creators: name: Shegelski, Mark Raymond Alphonse
Publisher: name: University of British Columbia
Year: 2010

description: In lightly doped semiconductors (LDSs), electrons can exist in localized states around impurities and dc electronic conduction can occur by electrons hopping between localized states. Such hopping is the dominant mechanism for conduction if the temperature is so low that the contribution from band electrons is negligible. According to theories of hopping conduction, at low enough temperature T, the conductivity σ will be o=σ₀e⁻(T₀/T)¼ where T₀ is a temperature which depends on the material. Experimental work on doped semiconductors which exhibits this form of σ is scarce. Recently, however, conductivities which were clearly of this form were reported for lightly doped n-GaAs and lightly doped n-InP. The experimental results were surprising in that the temperature ranges were well above, and the T₀ values well below, the limits set by the theories. To understand these experimental results, hopping in LDSs is modelled in this dissertation using a resistor network. This dissertation is unique in that the conductivity of the unabridged resistor network is examined in a temperature range (called "the high temperature regime") where kT is comparable to the spread ∆ε in the energies of localized electrons. A numerical simulation is performed and an analytic theory based on percolation methods is presented. In this dissertation, an analytic approach is developed for the first time for studying how, in the high temperature regime, the conductivity of the unabridged resistor network depends on the density of localized states. It is found that, in either two or three dimensions, if the density of states is flat, σ is of the activated form o=σ₀e ⁻εa/kt. The activation energies are found to be εa=0.28∆ε in two dimensions and εa =0.20∆ε in three dimensions. These values are considerable improvements over the estimates of previous workers, who used the low temperature asymptotic form of the resistance in the high temperature regime. It is also revealed that σ can be o=µσ₀e ⁻(T₀/T)¼ in the high temperature regime if the density of states decreases with |ε⁻µ₀| for energy e far enough away from the zero temperature chemical potential µ₀, These results are in accord with the experimental results described above.

description: The attitude of the medieval church towards violence before the First Crusade in 1095 underwent a significant institutional evolution, from the peaceful tradition of the New Testament and the Roman persecution, through the prelate-led military campaigns of the Carolingian period and the Peace of God era. It would be superficially easy to characterize this transformation as the pragmatic and entirely secular response of a growing power to the changing world. However, such a simplification does not fully do justice to the underlying theology. While church leaders from the 5th Century to the 11th had vastly different motivations and circumstances under which to develop their responses to a variety of violent activities, the teachings of Augustine of Hippo provided a unifying theme. Augustine’s just war theology, in establishing which conflicts are acceptable in the eyes of God, focused on determining whether a proper causa belli or basis for war exists, and then whether a legitimate authority declares and leads the war. Augustine masterfully integrated aspects of the Old and New Testaments to create a lasting and compelling case for his definition of justified violence. Although at different times and places his theology has been used to support a variety of different attitudes, the profound influence of his work on the medieval church’s evolving position on violence is clear.
Probing the quantum coherence of a nanomechanical resonator using a superconducting qubit: I. Echo scheme

Subjects: subject: Quantum Physics (quant-ph)

description: We propose a scheme in which the quantum coherence of a nanomechanical resonator can be probed using a superconducting qubit. We consider a mechanical resonator coupled capacitively to a Cooper-pair box and assume that the superconducting qubit is tuned to the degeneracy point so that its coherence time is maximised and the electro-mechanical coupling can be approximated by a dispersive Hamiltonian. When the qubit is prepared in a superposition of states this drives the mechanical resonator progressively into a superposition which in turn leads to apparent decoherence of the qubit. Applying a suitable control pulse to the qubit allows its population to be inverted resulting in a reversal of the resonator dynamics. However, the resonator's interactions with its environment mean that the dynamics is not completely reversible. We show that this irreversibility is largely due to the decoherence of the mechanical resonator and can be inferred from appropriate measurements on the qubit alone. Using estimates for the parameters involved based on a specific realization of the system we show that it should be possible to carry out this scheme with existing device technology.

description: A mechanism of light transmission through metallic films is proposed, assisted by tunnelling between resonating buried dielectric inclusions. This is illustrated by arrays of Si spheres embedded in Ag. Strong transmission peaks are observed near the Mie resonances of the spheres. The interaction among various planes of spheres and interference effects between these resonances and the surface plasmons of Ag lead to mixing and splitting of the resonances. Transmission is proved to be limited only by absorption. For small spheres, the effective dielectric constant can be tuned to values close to unity and a method is proposed to turn the resulting materials invisible.

description: The goal of this Health Humanities Portrait-- Life Without Shelter in the United States: Veterans and Homelessness--is to understand both the specificity and the commonality of being homeless as a veteran. Veterans have access to care through the Veterans Affairs (VA) medical system and are an object of historical reverence within American society. In many ways, however, the causes and experiences of their homelessness do not differ substantially from those of the general homeless population. The assigned transcripts and video clips capture historically significant issues relevant to our broad social theme, including the meanings of homelessness; the indignity of reliance on inadequate or poorly organized social services; the role of addiction and mental health concerns; housing instability and discrimination; work and the labor market; stereotypes and the stigma associated with homelessness; and the social obligation to veterans.
Studies of some acoustic resonant systems
Creators: name: Greaves, Thomas
Publisher: name: University of British Columbia
Year: 2010

description: The resonant frequency shift, δf, of an acoustic resonator by a small spheroidal obstacle is calculated. For a spheroid whose dimensions are small compared to the wavelength of the sound waves it is shown that δf can be expressed in terms of the spheroid geometry and the structure of the acoustic modes in the immediate vicinity of the spheroid, whereas in the usual method of calculating δf one needs to know the detailed structure of the normal modes of the resonator. Interest in the topic is motivated by current studies of the acoustical levitation of materials in microgravity environements. The significance of the results for the study of the acoustical levitation of liquid droplets in neutral buoyancy environments is discussed. With a view to applying these results, the mechanical properties of an electro-acoustic transducer with an impedance well matched to liquids are measured. The transducer consists of neoprene sandwiched between two conducting plates. The displacement of the transducer under different driving conditions has been measured usng an interferometric technique with angstrom sensitivity. An unusual feature of the interferometer is the degree of sensitivity achievable without vibration isolation mountings or temperature control of the environment. Using these measurements a qualitative model is developed to explain the unexpected aspects of the dynamical behavior of the transducer. The thesis concludes with-suggestions for further development of the transducer system.

description: We present optical UBVRI sky brightness measures from 1992 through 2006. The data are based on CCD imagery obtained with the CTIO 0.9-m, 1.3-m, and 1.5-m telescopes. The B- and V-band data are in reasonable agreement with measurements previously made at Mauna Kea, though on the basis of a small number of images per year there are discrepancies for the years 1992 through 1994. Our CCD-based data are not significantly different than values obtained at Cerro Paranal. We find that the yearly averages of V-band sky brightness are best correlated with the 10.7-cm solar flux taken 5 days prior to the sky brightness measures. This implies an average speed of 350 km/sec for the solar wind. While we can measure an enhancement of the night sky levels over La Serena 10 degrees above the horizon, at elevation angles above 45 degrees we find no evidence that the night sky brightness at Cerro Tololo is affected by artificial light of nearby towns and cities.

Similarly, W-shaped modes are supported by a double potential barrier. Families of the modes are constructed in a numerical form, and also by means of the Thomas-Fermi and variational approximations. All these modes are stable, which is predicted by computation of eigenvalues for small perturbations and confirmed by direct numerical simulations.

description: Die Dauerkrise der Allgemeinen Didaktik führt zu immer neuen Auseinandersetzungen rund um ihren Stellenwert und ihre Zukunftsfähigkeit. Dabei scheint ihr Status als (schul-)pädagogische Leitdisziplin spätestens mit der stärkeren Out-Put-Orientierung des Bildungssystems seit Anfang der 2000er-Jahre verloren. Dennoch beschäftigen sich nach wie vor zahlreiche Personen und Publikationen in – zum Teil stark selbstreferenziellen – Diskursen mit der Allgemeinen Didaktik, wobei neben Reformüberlegungen auch Abgrenzungen zu anderen Disziplinen eine große Rolle spielen. Wenig beachtet ist bislang jedoch der Stellenwert der Allgemeinen Didaktik in der (universitären) Lehrer*innenbildung, was umso mehr erstaunt, bedenkt man, dass durch eine hochschulische Verankerung auch die unterrichtsbezogene Ausrichtung und späteres berufliches Handeln mit beeinflusst werden. Der Beitrag greift diese Überlegungen auf und versucht sich in einer mehrstufigen Beleuchtung der Allgemeinen Didaktik in der aktuellen Lehrer*innenbildung, die sowohl Hochschullehrpersonen als auch curriculare Vorgaben und die Studierendenperspektive umfasst.

Migration of a single particle suspended in non-Newtonian fluid
Creators: name: Tuccillo, Teresa
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: In this thesis we study the motion of a 2D single, solid particle suspended in a viscoelastic fluid. We perform simulations by means of a finite elements method method. An ALE particle mover is combined with a DEVSS-G/SUPG formulation together with a log-representation of the conformation tensor, in order to easily manage the particle motion and significantly improve numerical convergence at finite Deborah numbers. Finally, the rigid-body motion on the particle boundary is imposed through Lagrange multipliers. First we will show that the particle moves towards a wall if immersed in a non-Newtonian fluid under continuous shear flow, in qualitative agreement with experimental findings. Anyway most of the experiments are performed under oscillatory shear flow, so we will study the effect of oscillation on the migration of the particle and we will compare our results with experimental data. Finally we will report results of migration when particle is moving between two concentric rotating cylinders. We will show that the migration is strongly affected by the curvature of the two cylinders. We will also show the effect of the suspending fluid and the particle size.
Chirurgia delle paratiroidi: dalla tecnica tradizionale alla M.I.R.P. (Minimally Invasive Radioguided Parathyroidectomy)
Creators: name: Scotti, Alessandro
Publisher: name: Università degli Studi di Napoli Federico II

description: Scopo dello studio è verificare i reali benefici della MIRP ( Minimally Invasive Radioguided Parathyroidectomy ) rispetto alla Paratiroidectomia classica. La MIRP grazie all’uso del Sesta MIBI come marcatore consente l’identificazione preoperatoria delle paratiroidi iperfunzionanti. Successivamente con l’uso di un gamma-counter intraoperatorio, l’isolamento e l’escissione di tali ghiandole risulta molto più semplice e sicura, anche nei casi di iperparatiroidismo secondario, migliorando i risultati e riducendo le complicanze
TACC3 mediates the association of MBD2 with histone acetyltransferases: a novel mechanism for reactivation of methylated promoters
Creators: name: Angrisano, Tiziana
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: We have recently reported that a novel MBD2 interactor (MBDin) has the capacity to reactivate transcription from MBD2-repressed methylated promoters even in the absence of demethylation events. Here we show that another unrelated protein, TACC3, displays a similar activity on methylated genes. In addition the data reported here provide possible molecular mechanisms for the observed phenomenon. Immunoprecipitation experiments showed that MBD2/TACC3 form a complex in vivo with the histone acetyltransferase pCAF. MBD2 could also associate with HDAC2, a component of MeCP1 repression complex. However, we found that the complexes formed by MBD2 with TACC3/pCAF and with HDAC2 were mutually exclusive. Moreover, HAT enzymatic assays demonstrated that HAT activity associates with MBD2 in vivo and that such association significantly increased when TACC3 was overexpressed. Overall our findings suggest that TACC3 can be recruited by MBD2 on methylated promoters and is able to reactivate transcription possibly by favoring the formation of an HAT-containing MBD2 complex and, thus, switching the repression potential of MBD2 in activation even prior to eventual demethylation.
Influenza di materie prime non convenzionali, grano saraceno e crusca, sui parametri qualitativi degli spaghetti in cottura

description: Al fine di valutare l’impiego di materie prime non convenzionali nella produzione industriale di pasta secca, 9 campioni di spaghetti sono stati prodotti impiegando, oltre al grano duro, percentuali crescenti di grano saraceno e crusca. Gli spaghetti ottenuti sono stati confrontati con uno standard commerciale di riferimento realizzato totalmente con semola. L’analisi sensoriale ha mostrato che all’aumentare del contenuto di grano saraceno e crusca si riducono il grado di ammassamento e di adesività dei campioni esaminati (parametri direttamente correlati alla collosità) e aumenta la consistenza degli stessi. Tali risultati sono stati confermati valutando la cinetica di idratazione degli spaghetti in cottura e sovracottura. In particolare, un modello matematico impiegato per la determinazione degli stress residui nello spaghetto è stato adattato ai dati sperimentali relativi alle variazioni di lunghezza, peso e diametro. In tal modo è stato anche possibile valutare l’influenza dell’aggiunta degli sfarinati sulla suscettibilità alla rottura dei singoli campioni. Inoltre, la determinazione del modulo elastico in tensione ha evidenziato l’influenza positiva del grano saraceno e della crusca sulla tenuta in cottura dei campioni. Infine, tramite l’analisi in componenti principali è stato possibile valutare il contributo apportato dai singoli sfarinati al raggiungimento delle performance di qualità mostrate dalla pasta in cottura rendendo così utili le informazioni acquisite per il trasferimento su scala industriale.

Risposta immunitaria e timoma: patogenesi della sindrome di Good
Creators: name: Vitiello, Laura
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: Il timoma è un raro tumore umano, originante dalle cellule epiteliali timiche, caratterizzato da una notevole associazione con disturbi del sistema immune che includono patologie autoimmuni e una severa forma di immunodeficienza. Gli aspetti immunobiologici associati ai timomi rendono questa patologia un modello unico per lo studio del ruolo del timo e dell’omeostasi linfocitaria in individui adulti. In particolare, in circa il 10% dei casi di timoma, i pazienti sviluppano  un’immunodeficienza severa caratterizzata da infezioni ricorrenti, principalmente a carico dell’apparato respiratorio, che possono rivelarsi letali per il paziente. Questa condizione patologica, nota come sindrome di Good, rappresenta ancora oggi una condizione a patogenesi non definita.
Lo scopo di questo studio è stato quello di definire gli aspetti patogenetici dell’immunodeficienza associata a timoma, caratterizzando una coorte di 50 pazienti, dei quali sono stati valutati lo stato e la funzionalità del sistema immunitario sia con metodiche di analisi convenzionali che con approcci molecolari più avanzati.
I risultati indicano l’associazione dell’immunodeficienza secondaria a timoma (sindrome di Good) con la perdita dei linfociti B circolanti e dei loro precursori midollari; una profonda alterazione del compartimento T, con l’espansione dei linfociti CD8+ naive a discapito degli effettori, e quindi una minore capacità di rispondere alle infezioni virali, la diminuzione dei linfociti T CD4, necessari tra l’altro alla generazione dei linfociti T Cd8+ memory, e la diminuzione dei linfociti Treg CD4+ CD25+, probabilmente implicata nella patogenesi delle patologie autoimmuni associate a timoma. L’analisi molecolare del repertorio TCR espresso dai linfociti del sangue periferico e di quelli infiltranti il midollo ha permesso di identificare nel clone T CD8+ VB8+ uno dei possibili responsabili delle alterazioni midollari che impediscono una corretta B linfopoiesi. La sindrome di Good, quindi, deve essere ridefinita come un’immunodeficienza combinata grave (SCID), in cui sono all’immunodeficit si associa la presenza dell’autoimmunità.
La proporzione tra le prestazioni contrattuali
Creators: name: Rinaldi, Carlo
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: La tesi è intesa ad indagare se e in quali limiti viga nel nostro sistema giuridico il principio di adeguatezza del corrispettivo contrattuale. Essa è articolata in quattro parti. Vengono preliminarmente delineati i rapporti tra i concetti di equilibrio contrattuale, giustizia contrattuale ed autonomia privata e successivamente individuati gli istituti ed i rimedi codicistici a tutela della proporzione contrattuale. In tale prospettiva, vengono analizzati la rescissione; la risoluzione per eccessiva onerosità sopravvenuta; le disposizioni inerenti all’oggetto del contratto ed al corrispettivo (ad es. gli artt. 1349 e 1474 c.c.); infine, la disciplina dell’incapacità naturale, del dolo e dell’errore. Si ripercorre, poi, l’iter giurisprudenziale in tema di proporzione contrattuale, a partire dalla originaria distinzione tra prezzo “vile” e prezzo “simbolico”, fino al successivo processo di oggettivazione dello scambio, realizzato attraverso la valorizzazione dell’elemento causale del contratto. Vengono, inoltre, esaminate le pronunce che attribuiscono alla buona fede una funzione integrativa e correttiva delle pattuizioni private sperequate, nonché i rapporti tra questa e l’equità. Lo sviluppo del lavoro investe il tema dell’equilibrio contrattuale alla luce della recente legislazione speciale, in particolar modo di derivazione comunitaria, finalizzata alla tutela del contraente debole, individuato nelle figure del consumatore e dell’imprenditore debole. Vengono, infine, presi in considerazione i Principi Unidroit ed i recenti progetti di codificazione europea, i quali riservano particolare attenzione all’equilibrio contrattuale, e, soprattutto, alle situazioni caratterizzate da asimmetria di potere contrattuale tra le parti.

description: Photonic crystal nanocavities at visible wavelengths are fabricated in a high refractive index (n>3.2) gallium phosphide membrane. The cavities are probed via a cross-polarized reflectivity measurement and show resonances at wavelengths as low as 645 nm at room temperature, with quality factors between 500 and 1700 for modes with volumes 0.7(lambda/n)^3. These structures could be employed for submicron scale optoelectronic devices in the visible, and for coupling to novel emitters with resonances in the visible such as nitrogen vacancy centers, and bio- and organic molecules.

description: Addressing the recent criticisms of Kvinikhidze and Miller, we prove that the spectator wave functions and currents based on ``fixed-axis'' polarization states (previously introduced by us) are Lorentz covariant, and find an explicit connection between them and conventional direction-dependent polarization states. The discussion shows explicitly how it is possible to construct pure $S$-wave models of the nucleon.
