The conservation of the endemic Crop Wild Relatives in the RIBES seed-banks: towards a national priority list for the Italian CWRs
2016
Data of 620 crop wild relatives of species of food and fodder interest listed in the Annex I of the FAO Treaty (FAO, 2001) were collected within the census carried out by ISPRA, the Italian National Institute for Environmental Protection and Research, in 2014-2015 in order to quantify the extent of CWR representation in the Italian ex situ collections. According to such census, the RIBES network preserve 37% of the Italian CWRs listed in the FAO Treaty: in 14 out of 16 seed-banks are preserved 6,029 accessions of 229 CWR taxa, belonging to 11 families and 57 genera.

STUDIO DEI MECCANISMI DI MORTE CELLULARI INDOTTI DAL CANNABINOIDE SINTETICO WIN IN CELLULE TUMORALI IN COLTURA
2014
Per lungo tempo, i cannabinoidi sono stati considerati come farmaci lenitivi ma non curativi della patologia cancerosa. Tuttavia, negli scorsi anni, è stata suggerita una potenziale applicazione dei cannabinoidi come droghe antitumorali, anche se il loro meccanismo d’azione non è ancora ben conosciuto. Gli obiettivi di questo studio sono stati: - la valutazione degli effetti del cannabinoide sintetico WIN55,212-2 (WIN) su differenti linee di cellule tumorali in coltura (cellule di carcinoma colorettale HT29 e cellule di osteosarcoma umano MG63) e – la valutazione dei meccanismi molecolari indotti dal trattamento con il cannabinoide. I risultati riportati indicano che in entrambe le linee ce…
Use of Modified 3D Scaffolds to Improve Cell Adhesion and Drive Desired Cell Responses.
2012
In the most common approach of tissue engineering, a polymeric scaffold with a well-defined architecture has emerged as a promising platform for cells adhesion and guide their proliferation and differentiation into the desired tissue or organ. An ideal model for the regeneration should mimic clinical conditions of tissue injury, create a permissive microenvironment for diffusion of nutrients, gases and growth factors and permit angiogenesis. In this work, we used a 3D support made of synthetic resorbable polylactic acid (PLLA), which has considerable potential because of its well-known biocompatibility and biodegradability. One of the factors that influence cell adhesion to the scaffold is …
EFFECT OF AUTOLOGOUS PLATELET-RICH PLASMA ON DISTRACTION OSTEOGENESIS IN THE MANDIBLE OF RABBITS: A MORPHOLOGIC AND MORPHOMETRIC APPROACH
2013
Distraction osteogenesis of the jaws is a common surgical practice in the treatment of pediatric craniofacial deformities. Autologous platelet rich plasma (PRP) has been used to increase the healing potential of bones in humans during distraction osteogenesis. This article aims to study the morphometric and morphologic parameters resulting from the effect of PRP on bone healing after mandibular distraction in rabbits. Right mandibular distraction was performed in 12 rabbits divided equally into 2 groups. PRP and physiological saline were injected, according to a defined protocol, in the callus following distraction of the experimental and control groups respectively. The rabbits were sacrif…

Protecting entanglement by adjusting the velocities of moving qubits inside non-Markovian environments
2017
Efficient entanglement preservation in open quantum systems is a crucial scope towards a reliable exploitation of quantum resources. We address this issue by studying how two-qubit entanglement dynamically behaves when two atom qubits move inside two separated identical cavities. The moving qubits independently interact with their respective cavity. As a main general result, we find that under resonant qubit-cavity interaction the initial entanglement between two moving qubits remains closer to its initial value as time passes compared to the case of stationary qubits. In particular, we show that the initial entanglement can be strongly protected from decay by suitably adjusting the velocit…
Predator population depending on lemming cycles
2016
In this paper, a Langevin equation for predator population with multiplicative correlated noise is analyzed. The noise source, which is a nonnegative random pulse noise with regulated periodicity, corresponds to the prey population cycling. The increase of periodicity of noise affects the average predator density at the stationary state.
