Structured reporting of rectal cancer staging and restaging: A consensus proposal

2021

Background: Structured reporting (SR) in oncologic imaging is becoming necessary and has recently been recognized by major scientific societies. The aim of this study was to build MRI-based structured reports for rectal cancer (RC) staging and restaging in order to provide clinicians all critical tumor information. Materials and Methods: A panel of radiologist experts in abdominal imaging, called the members of the Italian Society of Medical and Interventional Radiology, was established. The modified Delphi process was used to build the SR and to assess the level of agreement in all sections. The Cronbach’s alpha (Cα) correlation coefficient was used to assess the internal consistency of ea…

Baveno VII – Renewing consensus in portal hypertension

2022

To expand on the work of previous meetings, a virtual Baveno VII workshop was organised for October 2021. Among patients with compensated cirrhosis or compensated advanced chronic liver disease (cACLD – defined at the Baveno VI conference), the presence or absence of clinically significant portal hypertension (CSPH) is associated with differing outcomes, including risk of death, and different diagnostic and therapeutic needs. Accordingly, the Baveno VII workshop was entitled “Personalized Care for Portal Hypertension”. The main fields of discussion were the relevance and indications for measuring the hepatic venous pressure gradient as a gold standard, the use of non-invasive tools for the …

Necrobia rufipes (De geer) infestation in pet food packaging and setup of a monitoring trap

2020

Simple Summary Necrobia rufipes (Coleoptera: Cleridae) is an emerging pest of pet food stores. Information on infestation modalities for this pest is absent and specific monitoring tools are missing. In this paper, the adults’ and larvae’s ability to enter into pet food packaging was evaluated. Furthermore, to set up of a monitoring trap behavioral bioassays were carried out: testing two adhesive surfaces, one generally used in mouse glue trap and the other used in cockroach trap, to evaluate their ability in avoiding insects’ escape; screening different molecules, as candidate food attractants: methyl cyclopentenolone, squalene and stearic acid. The results evidenced that N. rufipes enter …

Moderate overexpression of glucose-6-phosphate dehydrogenase improves healthspan in mice. Implications in skeletal muscle regeneration

2019

An enormous increment in the average lifespan of diverse populations occurred worldwide in the 20th century. In the last 10–15 years, the importance has changed from extending average and even maximal longevity to favoring healthy aging, and many researchers have focused their studies on the aim at extending healthspan. Prolonging lifespan without taking care of improving healthspan can derive in a long time of living with disabilities and constitutes a risk factor for the old population to suffer a higher prevalence of aging-related diseases. Indeed, modern disease treatments frequently diminish mortality without any effect on the deterioration of overall health. Understanding the mechanis…

Giuseppe Cocchiara, il fascismo e il razzismo

2021

In questo saggio viene ricostruito il rapporto tra Giuseppe Cocchiara e il fascismo. L’antropologo visse in pieno la sua formazione culturale all'interno del regime al quale aderì con convinzione e slancio, militando sempre nelle sue fazioni più radicali, condividendone fedelmente le scelte più tragiche come la guerra d’Etiopia, sottoscrivendo le leggi razziali, impegnandosi nella seconda guerra mondiale con le armi culturali dell’antisemitismo e della lotta senza tregua contro la democrazia. Così quando, come in un «mondo alla rovescia», sconfitto il fascismo sotto il peso di un’umiliante e sanguinosa disfatta, saranno proprio gli odiati inglesi a valorizzarne la statura intellettuale e la…

Validating Habitual and Goal-Directed Decision-Making Performance Online in Healthy Older Adults

2021

Everyday decision-making is supported by a dual-system of control comprised of parallel goal-directed and habitual systems. Over the past decade, the two-stage Markov decision task has become popularized for its ability to dissociate between goal-directed and habitual decision-making. While a handful of studies have implemented decision-making tasks online, only one study has validated the task by comparing in-person and web-based performance on the two-stage task in children and young adults. To date, no study has validated the dissociation of goal-directed and habitual behaviors in older adults online. Here, we implemented and validated a web-based version of the two-stage Markov task usi…

HYPERBLEND: SIMULATING SPECTRAL REFLECTANCE AND TRANSMITTANCE OF LEAF TISSUE WITH BLENDER

2022

Abstract. Remotely sensing vegetation condition and health hazards requires modeling the connection of plants’ biophysical and biochemical parameters to their spectral response. Even though many models exist already, the field suffers from lack of access to program code. In this study, we will assess the feasibility of open-source 3D-modeling and rendering software Blender in simulating hyperspectral reflectance and transmittance of leaf tissue to serve as a base for a more advanced large-scale simulator. This is the first phase of a larger HyperBlend project, which will provide a fully open-source, canopy scale leaf optical properties model for simulating remotely sensed hyperspectral imag…

Switching spatial scale reveals dominance-dependent social foraging tactics in a wild primate

2017

When foraging in a social group, individuals are faced with the choice of sampling their environment directly or exploiting the discoveries of others. The evolutionary dynamics of this trade-off have been explored mathematically through the producer-scrounger game, which has highlighted socially exploitative behaviours as a major potential cost of group living. However, our understanding of the tight interplay that can exist between social dominance and scrounging behaviour is limited. To date, only two theoretical studies have explored this relationship systematically, demonstrating that because scrounging requires joining a competitor at a resource, it should become exclusive to high-rank…
