Incremento della temperatura lungo la superficie radicolare durante la tecnica dell’onda continua di condensazione
2008
INTRODUZIONE: Le temperature raggiunte degli strumenti portatori di calore, durante la condensazione a caldo della guttaperca, sono molto elevate. Ciò potrebbe rappresentare una fonte di danno iatrogeno a livello delle strutture parodontali sottoposte ad un eccessivo stress termico. SCOPO DEL LAVORO: Valutazione termografica a infrarossi dell’incremento della temperatura lungo la superficie radicolare, durante la tecnica dell’onda continua di condensazione. MATERIALI E METODI: Venti incisivi laterali mascellari, estratti per motivi parodontali, sono stati selezionati e alesati con M-two. In tutti i campioni è stata eseguita un’otturazione canalare mediante coni di guttaperca non standardizz…

« Un inconnu dans la maison : l’enfant dans ¿ Quién puede matar a un niño ? (Narciso Ibáñez Serrador, 1974) »
2008
This article deals with ¿Quién puede matar a un niño? directed by Narciso Ibáñez Serrador, more famous thanks to his TV film series Historias para no dormir. In this film, children use to play an essential part in the development of a pure fantastic style (in Todorov’s terms), i.e. based on the irruption of unexplainable elements inside a perfectly normal realistic context. As some critics as Rosset have pointed out, the feeling of anguish does arise from such a realistic context, from that otherness within the child, the human being we are more reluctant to fear, the one we hardly view with suspicion Este artículo trata de la obra de Narciso Ibáñez Serrador y, en particular, de uno de sus …
Laser fluence, repetition rate and pulse duration effects on paint ablation
2006
Abstract The efficiency (mm3/(J pulse)) of laser ablation of paint was investigated with nanosecond pulsed Nd:YAG lasers (λ = 532 nm) as a function of the following laser beam parameters: pulse repetition rate (1–10,000 Hz), laser fluence (0.1–5 J/cm2) and pulse duration (5 ns and 100 ns). In our study, the best ablation efficiency (η ≅ 0.3 mm3/J) was obtained with the highest repetition rate (10 kHz) at the fluence F = 1.5 J/cm2. This ablation efficiency can be associated with heat accumulation at high repetition rate, which leads to the ablation threshold decrease. Despite the low thermal diffusivity and the low optical absorption of the paint (thermal confinement regime), the ablation th…
Thermoluminescence response of sodalime glass irradiated with photon and electron beams in the 1-20 Gy range
2011
Abstract The thermoluminescence response of a watch commercial glass was studied after irradiation with photons and electrons, in the range 1–20 Gy, of interest in accidental dosimetry; a linear response was obtained with both beams. This result, together with the satisfactory time stability of the thermoluminescence signal, indicates this glass as a potential material for retrospective dosimetry applications.
Time-like Proton Form Factors with Initial State Radiation Technique
2022
Electromagnetic form factors are fundamental quantities describing the internal structure of hadrons. They can be measured with scattering processes in the space-like region and annihilation processes in the time-like region. The two regions are connected by crossing symmetry. The measurements of the proton electromagnetic form factors in the time-like region using the initial state radiation technique are reviewed. Recent experimental studies have shown that initial state radiation processes at high luminosity electron-positron colliders can be effectively used to probe the electromagnetic structure of hadrons. The BABAR experiment at the B-factory PEP-II in Stanford and the BESIII experim…
Modified Glasgow Prognostic Score is Associated With Risk of Recurrence in Bladder Cancer Patients After Radical Cystectomy
2015
Recently, many studies explored the role of inflammation parameters in the prognosis of urinary cancers, but the results were not consistent. The modified Glasgow Prognostic Score (mGPS), a systemic inflammation marker, is a prognostic marker in various types of cancers. The aim of the present study was to investigate the usefulness of the preoperative mGPS as predictor of recurrence-free (RFS), overall (OS), and cancer-specific (CSS) survivals in a large cohort of urothelial bladder cancer (UBC) patients.A total of 1037 patients with UBC were included in this study with a median follow-up of 22 months (range 3-60 months). An mGPS = 0 was observed in 646 patients (62.3%), mGPS = 1 in 297 pa…
Tonsillolith : a report of three clinical cases
2007
Tonsillolith is a rare dystrophic calcification as a result of chronic inflammation of the tonsils. Three asymptomatic cases of tonsillolith are reported, incidentally discovered through panoramic radiographs, which showed different sizes of radiopaque images, varying from 2 to 5mm; cases I and III images did not overlap the mandible ramus, which led to a probable diagnosis of soft tissue calcification. Case II had radiopaque unilateral images, with osseous tissue density, overlapping the mandibular ramus, leading to a benign intra-osseous lesion, which was considered as differential diagnosis. No symptoms were reported in any case. Only case I had clinical characteristics, showing highly c…
Evaluation of Surgical Outcomes of Abdominal Radical Hysterectomy and Total Laparoscopic Radical Hysterectomy for Cervical Cancer: A Retrospective An…
2022
Although a surgical approach is one of the key treatments for stages IA1-IIA2, results of the Laparoscopic Approach to Cervical Cancer (LACC) published in 2018 radically changed the field, since minimally invasive surgery was associated with a four-fold higher rate of recurrence and a six-fold higher rate of all-cause death compared to an open approach. We aimed to evaluate surgical outcomes of abdominal radical hysterectomy (ARH) and total laparoscopic radical hysterectomy (TLRH) for cervical cancer, including data collected before the LACC trial. In our retrospective analysis, operative time was significantly longer in TLRH compared to ARH (p < 0.0001), although this disadvantage could…
