A Magnetic Resonance Imaging–Based Prediction Model for Prostate Biopsy Risk Stratification

2018

IMPORTANCE: Multiparametric magnetic resonance imaging (MRI) in conjunction with MRI–transrectal ultrasound (TRUS) fusion-guided biopsies have improved the detection of prostate cancer. It is unclear whether MRI itself adds additional value to multivariable prediction models based on clinical parameters. OBJECTIVE: To determine whether an MRI-based prediction model can reduce unnecessary biopsies in patients with suspected prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: Patients underwent MRI, MRI-TRUS fusion-guided biopsy, and 12-core systematic biopsy in 1 session. The development cohort used to derive the prediction model consisted of 400 patients from 1 institution enrolled between …

Effectiveness of substituting cyclosporin A with tacrolimus in reducing gingival overgrowth in renal transplant patients

2009

Objectives: this study aims to evaluate the effectiveness of periodontal therapy combined with tacrolimus in the suppression of gingival overgrowth (GO) and the effect on GO of changing from cyclosporin A to tacrolimus. Patients and methods: sixteen renal transplant patients, averaging 52 years of age, whose kidney function was stable and were receiving treatment with cyclosporin A, were randomly assigned to one of two groups. In the experimental group, patients were instructed in oral hygiene and underwent periodontal treatment, whereas in the control group, only oral hygiene instructions were given. After the first visit and the change of medication from cyclosporine to tacrolimus in both…

Dissensus, death and division

2009

The modeling of switching systems describing networks where death and duplication processes occur is described. A dissensus protocol, complementary to consensus protocol, is introduced and the convergence or divergence of the agents' state evolution is studied. We discuss some properties of the topology reached by the network when different rules of duplication and inheritance are implemented.

Why Do We Take Risks? Perception of the Situation and Risk Proneness Predict Domain-Specific Risk Taking

2021

[EN] Risk taking (RT) is a component of the decision-making process in situations that involve uncertainty and in which the probability of each outcome - rewards and/or negative consequences - is already known. The influence of cognitive and emotional processes in decision making may affect how risky situations are addressed. First, inaccurate assessments of situations may constitute a perceptual bias in decision making, which might influence RT. Second, there seems to be consensus that a proneness bias exists, known as risk proneness, which can be defined as the propensity to be attracted to potentially risky activities. In the present study, we take the approach that risk perception and r…

Inclusive Design for Alzheimer’s Disease: Low-cost Treatments, Design and ICT

2019

Inability to acquire new memories, difficulty to remember recent events and to recognize objects, places and people, visual-spatial disorientation, these are some of the disorders with which who is affected by neurological diseases must learn to live with. In a continuously evolving society, where the decreasing birth rate and the drops in mortality are consistent, the job of Architecture is precisely to interpret the requirements and needs of people who have lost the canonical relationship with the world and give them the possibility to recover it or maintain it through communication channels that use their remaining ability to understand. The indoors and outdoors acquire a “prosthesis fun…

Incapacità di acquisire nuovi ricordi difficoltà nel ricordare eventi osservati recentemente mancata identificazione delle cose dei luoghi e delle persone disorientamento visivo-spaziale sono questi e molti altri i disturbi con cui devono imparare a convivere coloro che sono colpiti da malattie neurologiche. In una società in continua evoluzione dove la diminuzione della natalità e l’innalzamento della soglia di mortalità divengono costanti il compito dell’Architettura è proprio quello d’interpretare le esigenze e i bisogni di persone che hanno perso il rapporto canonico con il mondo e offrire loro le possibilità di recuperarlo o di mantenerlo attraverso canali di comunicazione che sfruttino le loro residue capacità di comprensione. Lo spazio interno ed esterno assume così una “funzione protesica” contenendo ed esprimendo in sé le conoscenze necessarie per la sua corretta fruizione riducendo il senso di frustrazione attraverso la sensazione di sicurezza e di benessere che il malato deve percepire vivendolo. Il presente saggio propone un contributo alla diffusione di conoscenze e di informazioni utili a coloro che operano nel settore della programmazione e della progettazione di strutture socio-sanitarie riportando soluzioni terapeutiche “non farmacologiche” low-cost e sostenibili promosse dalla ricerca tecnologica internazionale e nazionale nel settore della progettazione tecnologica e delle ICT e che hanno dimostrato di essere in grado di produrre significativi benefici sia ai malati sia ai caregivers.Settore ICAR/12 - Tecnologia Dell'Architettura

Total RNA-isolation of abdominal hernia of rats for quantitative real-time reverse transcription (RT) PCR assays.

2007

Abstract Increasing complications in incisional hernia surgery call for novel treatments. A gene expression analysis of injured tissues displays important parameters for tissue regeneration. Until today, no reliable method has been described for a quantitative gene expression analysis of hernia tissues. In this work, a protocol is described for the isolation of DNA‐free total RNA of incisional hernias for the first time. Moreover, real‐time RT PCR assays for collagen type I and III and TGF‐β1 are demonstrated for relative gene expression analyses. Both methods enable relative gene expression analyses of hernia tissues for the first time.

Continuous spectrum for a two phase eigenvalue problem with an indefinite and unbounded potential

2020

Abstract We consider a two phase eigenvalue problem driven by the ( p , q ) -Laplacian plus an indefinite and unbounded potential, and Robin boundary condition. Using a modification of the Nehari manifold method, we show that there exists a nontrivial open interval I ⊆ R such that every λ ∈ I is an eigenvalue with positive eigenfunctions. When we impose additional regularity conditions on the potential function and the boundary coefficient, we show that we have smooth eigenfunctions.

Il maschile e il femminile. Una riflessione sulla radice di senso dell'identità di genere

2014

Il tema del maschile e del femminile e il senso della loro reciprocità è percepito come problematico in una cultura come quella attuale, segnata da una propensione all’indifferenziazione sessuale. La questione, per l’elaborazione di un’antropologia pedagogica della sponsalità e della paternità/maternità, è nodale. Il saggio propone una riflessione di stile fenomenologico, volta a ritrovare la radice di senso delle categorie di maschilità e di femminilità, ritrovandole nell’aspetto per cui esso si mostrano costitutive dell’esistenza personale. Tale senso originario resta sempre presente in ogni ricerca e in ogni momento della costruzione della propria singolare identità di genere.
