No full textLa tesi costituisce il primo tentativo di catalogazione dei dipinti di Giulio Cesare Procaccini (Bologna 1574- Milano 1625).
Nei saggi introduttivi sono ripercorsi la fortuna critica dell’artista, la sua vita e la sua attività di pittore, quest’ultima riletta anche alla luce della produzione scultorea e grafica del maestro, parti integranti della sua articolata personalità. Costante è anche il riferimento al contesto della pittura milanese di primo Seicento, del quale Procaccini fu uno dei maggiori esponenti insieme a Cerano, Morazzone e al più giovane Daniele Crespi.
Ai testi seguono le schede di catalogo delle opere, ordinate secondo un criterio cronologico, dove compaiono le indicazioni relative alle copie e alle incisioni.
A conclusione delle schede delle prove ritenute autografe, una sezione è dedicata ad alcune composizioni che, consideratane l’ampia fortuna, sono con buona verosimiglianza copie da prototipi perduti di Procaccini, mentre in quella seguente si dà conto delle opere espunte dal catalogo dei dipinti autografi.
Nell’ottica di fornire uno strumento utile agli studi successivi su Giulio Cesare Procaccini, si è inoltre compilata una lista di opere perdute attestate dalle fonti e nell’ultima parte della tesi, oltre alla bibliografia conclusiva, il regesto dei documenti ripercorre, ad annum, le vicende del maestro sinora note.This thesis constitutes the first attempt to catalogue the paintings of Giulio Cesare Procaccini (Bologna 1574 - Milan 1625).
Introductory chapters address the artist's critical fortune, his life and his activity as painter, the latter also reconsidered bearing in mind his graphic and sculptural oeuvre, which played a significant role in his multi-structured personality. Constant contextual reference is made to Milanese painting of the early seventeenth century, of which Procaccini was one of the major exponents together with Cerano, Morazzone and their younger contemporary Daniele Crespi.
These texts are followed by a catalogue of works, chronologically arranged and accompanied by references to copies and engravings. Entries on what are accepted as autograph works are followed by a section about certain compositions, which - given their widespread success - are in all likelihood copies of lost prototypes by Procaccini, while the section that follows deals with paintings that have been rejected from the catalogue of autograph works.
With a view to offering a useful tool for future scholarship on Giulio Cesare Procaccini, the author also provides a list of lost or untraced works recorded in historical sources, and the final part of the thesis, in addition to a bibliography, contains a register of documents listing all that is known thus far about the master's life, year by year

Differential Leaf Age-Dependent Thermal Plasticity in the Keystone Seagrass Posidonia oceanica
No full textIntroduction: Gene-expression patterns and their upstream regulatory mechanisms (e.g. epigenetic) are known to modulate plant acclimatability and thus tolerance to heat stress. Within species, thermal plasticity (i.e. temperature-sensitive phenotypic plasticity) and differential thermo-tolerance are recognized among different genotypes, development stages, organs or tissues. Leaf age and lifespan have been demonstrated to strongly affect photosynthetic thermo-tolerance in terrestrial species, whereas there is no information available for marine plants. Materials and Methods: Here, we investigated how an intense warming event affects molecular and photo-physiological functions in the large-sized seagrass Posidonia oceanica, at fine spatial resolution. Plants were exposed for one week at 34°C in a controlled-mesocosm system. Subsequent variations in the expression of 12 target genes and global DNA methylation level were evaluated in three leaf-age sections (i.e. basal, medium and high) established along the longitudinal axis of youngest, young and fully mature leaves of the shoot. Targeted genes were involved in photosynthesis, chlorophyll biosynthesis, energy dissipation mechanisms, stress response and programmed cell death. Molecular analyses paralleled the assessment of pigment content and photosynthetic performance of the same leaf segments, as well as of plant growth inhibition under acute warming. Results: Our data revealed, for the first time, the presence of variable leaf age-dependent stress-induced epigenetic and gene-expression changes in seagrasses, underlying photo-physiological and growth responses to heat stress. An investment in protective responses and growth arrest was observed in immature tissues; while mature leaf sections displayed a higher ability to offset gene down-regulation, possibly through the involvement of DNA methylation changes, although heat-induced damages were visible at photo-physiological level. Discussion: Overall, mature and young leaf tissues exhibited different strategies to withstand heat stress and thus a variable thermal plasticity. This should be taken in consideration when addressing seagrass response to warming and other stressors, especially in large-sized species, where sharp age differences are present within and among leaves, and other gradients of environmental factors (e.g. light) could be at play. Molecular and physiological evaluations conducted only on adult leaf tissues, as common practice in seagrass research, could give inadequate estimates of the overall plant state, and should not be considered as a proxy for the whole shoot
Ultrasound and three-dimensional image reconstruction angio-computed tomography scan for hybrid surgical tracheostomy in patient with abnormal neck vascularization
No full textPercutaneous dilatational tracheostomy is a common and safe ICU procedure. However, neck anatomy variations can cause bleeding. Pre-procedural ultrasound should be carried out to detect abnormalities in neck structures. A 3D image reconstruction angio-computed tomography scan of the epiaortic vessels should be performed for precise planning of actions. We describe a hybrid tracheostomy technique required following an anomalous vascularization of the neck discovered preoperatively by echography and imaging method
SENTINEL LYMPH NODE BIOPSY IN THE TREATMENT OF BREAST CANCER. EXPERIENCE IN 527 CASES
No full textKnowledge of axillary lymph node status is a key aid to staging and prognosis and it represents a guideline for adjuvant therapy in breast cancer. Despite the morbidity it causes, complete axillary dissection was long the mainstay of treatment. Sentinel lymph node biopsy has proved so reliable in the evaluation of node involvement that axillary node dissection is now generally performed when sentinel node biopsy tests negative. METHODS: In this 3-phase study, 50 patients were enrolled to evaluate the learning curve of sentinel node biopsy (phase 1, September 1997-January 1998); 256 patients (age range 27-81 years) with infiltrative breast cancer (T <3 cm, clinical N0) underwent level 1 lymph node dissection when the sentinel node tested negative at histopathology (phase 2, February 1998-March 2001); 221 patients with T <3 cm underwent dissection of the sentinel node when it tested negative for metastasis (phase 3, April 2001-March 2005). RESULTS: The sentinel node was preoperatively detected in 98.6% of cases after peritumoral and intradermic injection of the radionuclide tracer and intraoperatively in 99% (90% with radio-guided surgery, 10% with vital staining). The sentinel node was positive in 15% of patients with T1 and metastatic in 65%. CONCLUSIONS: Our results are in line with the published data; therefore, the study will go forward to examine the role of the micrometastasis in the sentinel node and of in-transit tumoral cells

VATS anatomic resections for lung cancer: insights from the Italian VATS Group
No full textBackground: The VATS Group and the National Register for VATS Lobectomy were set up in 2013.
Both quality and quantity of collected data within the database are two fundamental tools for scientific and
statistical purposes, similar to other important databases, such as the European Society of Thoracic Surgeons
(ESTS) Database, the Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTSD) and
the Danish Lung Cancer Registry (DLCR).
Methods: Four thousand seven hundred and four VATS lobectomy patients have recruited to date. Several
parameters were recorded, such as preoperative clinical condition, surgical treatment as far as technical
details, postoperative course and follow-up.
Results: The Eastern Cooperative Oncology Group (ECOG) performance status was 0.27. Uniportal
approach was used in 332 patients, three-portal approach in 3,825 and bi-portal approach in 547.
Lymphadenectomy was performed in 4,704 patients: a sampling nodal dissection in 1,180 patients and a
radical nodal dissection in 3,524 cases. Conversion rate was in 9.99% of cases. Adenocarcinoma is the most
common histologic type (53.34%), followed by squamous carcinoma (15.53%).
Conclusions: The structure of the Italian Registry of VATS Lobectomy makes it a valid source to draw on
for statistical studies for scientific purposes
Riqualificazione dell'area industriale di Porta Volta : isolato di via Procaccini
No full textLAUREA MAGISTRALERiqualificazione dell’area industriale ex-Enel di P
orta Volta: isolato di via
Procaccini.
Il progetto si trova a Milano via Giulio Cesare Pro
caccini, nel centro storico della città di fronte
al Cimitero Monumentale. Negli ultimi 100 anni ques
ta zona era una zona industriale della
società Enel.
Nell'ultimo secolo la città ha rafforzato il propri
o ruolo economico e produttivo, divenendo il
maggiore mercato finanziario italiano. Inoltre è un
a delle capitali mondiali della moda,
del disegno industriale ed uno dei poli universitar
i italiani più importanti.
Nel corso degli anni, la città ha subito una grande
crescita e tutte le attività industrali situate
all’interno del centro storico, sono state spostate
verso la periferia lasciando questa zona
abbandonata e pronta ad assumere un nuovo ruolo.
L'idea del progetto è quella di attirare la gente i
n questa zona confortevole dove vivere,
lavorare e divertirsi.
L'edificio principale di 5 piani, compreso il piano
interrato, è stato conservato, restaurato
(sono state mantenute tutte le facciate originarie
che si affacciano sulla strada mentre le altre
sono state completamente risistemate) e trasformato
in un edificio prevalentemente
residenziale, con funzione di studentato. I tre pia
ni superiori sono residenziali e al piano terra
trova posto una zona commerciale; mentre il piano
interrato ospita alcuni locali tecnici e
servizi di lavanderia. Inoltre è stata predisposta,
all’interno del cortile, una nuova area di
parcheggio fruibile sia dai residenti che dagli ute
nti della nuova mediateca. Questa è stata
posta all’interno di un vecchio capannone industria
le appartenente al vecchio complesso
industriale dell’Enel che si situa proprio al centr
o del cortile interno. Una parte dei capannoni
piu bassa è stata demolita per dare più spazio all’
interno per Ie manovre e per fare entrare
una maggior quantità di luce; invece l’altra parte,
con un’altezza di 11 metri, offre due livelli di
area espositiva, biblioteca, zona wi-fi, bar e caff
etteria.
Su via Giovanni Battista Niccolini è stato aperto u
n nuovo ingresso che permette l’accesso
pedonale diretto al cortile interno e di conseguenz
a alla Mediateca, in particolare dal Cimitero
Monumentale. Su via Procaccini si trova l’accesso p
edonale e carrabile
The use of suprapectineal plate in acetabular fractures via ilioinguinal approach with Stoppa window
No full textOBJECTIVE: The aim of the study was to investigate the clinical results of open reduction and internal fixation using a suprapectineal buttress plate for specific acetabular fractures. METHODS: We conducted a retrospective study involving thirty-three patients with specific acetabular fractures in an academic level 2 trauma center. We performed the ilioinguinal approach with Stoppa window for buttress plating of the quadrilateral surface. Clinical examination, radiographs and computed tomography were done using criteria described by Matta. Functional outcome was evaluated by visual analog scale (VAS), WOMAC, Harris Hip score modified, Hip disability and Osteoarthritis Outcome Score (HOOS) and modified Merle d’Aubignè scoring system. RESULTS: Average follow-up was 40.4 months with a minimum of 24 months. Mean age was 59.09 years. The 82% of patients were treated with a suprapectineal plate using ilioinguinal approach with Stoppa window. The 18% of patients required a Kocher-Langenbeck approach in order to get anatomic reduction of posterior wall or column. The 91% of patients were satisfied of their condition during activity of day living and only a small cohort reported walking aids. The worst clinical results were obtained in patients characterized by highest step displacement. Deep infection of surgical wound was observed in 6% of patients. In 3% of patients, one vascular injury occurred during surgery. CONCLUSION: Internal fixation using ilioinguinal approach with Stoppa window and a suprapectineal plate to buttress the quadrilateral plate should be considered a viable treatment of some acetabular fractures. Patients can expect a good functional outcome with a low complication rate
Aircraft tyres – measurement of mechanical characteristics
No full textThe paper is devoted to the measurement of aircraft tyres’ characteristics. Namely the low and high frequency characterisation of aircraft tyres is performed. A new testing system for the indoor characterisation of aircraft tyres is presented. Two test rigs, one for the low frequency and one for high frequency tests, have been designed and realised. Measured data are processed according with the standard PAC2002, together with a short-wavelength intermediate frequency (SWIFT) model and a 3D tandem cam filter for high frequency dynamic and obstacle enveloping, i.e., the tyre model developed for automotive tyre has been employed to describe the behaviour of aircraft tyres. The results show that the low frequency behaviour of aircraft tyres can be accurately reproduced by PAC2002. Obstacle enveloping and high frequency characteristics are captured by the considered model with a sufficient degree of accuracy for engineering applications. Should dedicated noise-vibration harshness simulations be performed, this model, developed for automotive applications, should be revised for aircraft tyres
