Efecto terapéutico del compuesto BO-110 en un modelo animal de leiomioma
2023
Los miomas son los tumores benignos más frecuentes en las mujeres en edad reproductiva y pueden asociar numerosos síntomas como dolor, sangrado y problemas reproductivos. Sin embargo, actualmente no existe una terapia totalmente satisfactoria por lo que es de suma importancia la evaluación de nuevos tratamientos. En la búsqueda de opciones terapéuticas alternativas, hemos seleccionado el ácido poliinosina-policitidílico (pIC) conjugado con polietilenimina (PEI) [pICPEI], cuyo nombre comercial es BO-100. El compuesto pIC es un ARN sintético de doble cadena sin toxicidad asociada, que induce de manera selectiva la autofagia y apoptosis en un gran espectro de células tumorales. Presen…
Pinning of a kink in a nonlinear diffusive medium with a geometrical bifurcation: Theory and experiments
2004
International audience; We study the dynamics of a kink propagating in a Nagumo chain presenting a geometrical bifurcation. In the case of weak couplings, we define analytically and numerically the coupling conditions leading to the pinning of the kink at the bifurcation site. Moreover, real experiments using a nonlinear electrical lattice confirm the theoretical and numerical predictions.
High Bias Voltage CZT Detectors for High-flux Measurements
2017
In this work, we present the performance of new travelling heater method (THM) grown CZT detectors, recently developed at IMEM-CNR Parma, Italy. Thick planar detectors (3 mm thick) with gold electroless contacts on CZT crystals grown by Redlen Technologies (Victoria BC, Canada) were realized, with a planar cathode covering the detector surface (4.1 x 4.1 mm(2)) and a central anode (2 x 2 mm(2)) surrounded by a guard ring electrode. The detectors, characterized by low leakage currents at room temperature (4.7 nA/cm(2) at 1000 V/cm), allow good room temperature operation even at high bias voltages (> 7000 V/cm). At low rates, the detectors exhibit an energy resolution around 4 % FWIEM at 59.5…
Random utility approach to re-design passengers interchange nodes
2009
The passengers interchange node is a complex infrastructure, where the user can choose among different modal options to do his/her trip. These transport infrastructures have various terminals (car park, bus stop, metro, light rail, railway, extra-urban and sub urban bus and so on). The passengers, inside interchange node, have to reach these terminals walking often with luggage and for long distances. We calibrated a discrete choice model taking into account attributes able to explain the passenger behaviour by observed flows and generalized least squares technique. Furthermore an ex ante / ex post analysis was carried out in order to design and evaluate measure to incentive modal integrati…
Biological and Proteomic Characterization of the Anti-Cancer Potency of Aqueous Extracts from Cell-Free Coelomic Fluid of Arbacia lixula Sea Urchin i…
2022
Echinoderms are an acknowledged source of bioactive compounds exerting various beneficial effects on human health. Here, we examined the potential in vitro anti-hepatocarcinoma effects of aqueous extracts of the cell-free coelomic fluid obtained from the sea urchin Arbacia lixula using the HepG2 cell line as a model system. This was accomplished by employing a combination of colorimetric, microscopic and flow cytometric assays to determine cell viability, cell cycle distribution, the possible onset of apoptosis, the accumulation rate of acidic vesicular organelles, mitochondrial polarization, cell redox state and cell locomotory ability. The obtained data show that exposed HepG2 cells under…
Adaptive range-based localization algorithm based on trilateration and reference node selection for outdoor wireless sensor networks
2022
Locating the nodes of outdoor wireless sensor networks (WSNs) using (tri)lateration with a low-cost ranging technique, such as the received signal strength indicator (RSSI), often results in inaccurate location estimates. This can mostly be explained by the combined effect of distance estimate errors and localization geometry, both of which are subject to the reference nodes used. To develop techniques for reducing localization error, the distance estimate errors and localization geometry must be analyzed and taken into account. To address these challenges, this paper aims to seek ways to improve the quality of range-based trilateration localization for WSN nodes in varying outdoor conditio…
PROGETTARE LO SPAZIO INTERCULTURALE. Approccio multi-scalare nel quartiere Albergheria a Palermo / DESIGNING INTERCULTURAL SPACE. A multi-scalar appr…
2020
Migration has always been a major driver of urban transformation stimulating opportunities and challenges for cities and encouraging architectural and urban designers for taking a proactive and dynamic role in responding to the crisis. Enhancing these changes, and designing intercultural spaces for local communities, is a complex and urgent spatial challenge, that should be addressed by a multi-scalar approach aiming to integrate urban, architectural and public spaces. This paper illustrates a research-action resulting from a collective work developed on key urban spaces of the Albergheria neighborhood of Palermo, where a design-led research based on a multiscalar regeneration approach (urb…
Sapņu dienasgrāmata
2016
Tīmekļa lietotne “Sapņu dienasgrāmata” ļauj lietotājiem dokumentēt sapņu un dienas notikumus (ierakstus) privātās digitālās dienasgrāmatas veidā savstarpējai analīzei, kā arī sevis analizēšanai. Lietotne ļauj lietotājam formulēt savienojumus starp dienas un sapņu ierakstiem, kuri ir pašanalīzes rezultāti. Mērķis ir piedāvāt objektīvu rīku sevis analīzei caur sapņiem, nebalstoties uz psihoanalīzes skolām, t.i., necensties pateikt lietotājam kā analizēt sapņus. Projekta izstrāde notiek ar spējās (Agile) izstrādes pieeju, regulāri paplašinot un izstrādājot funkcionalitāti, balstoties uz regulārām SCRUM tikšanām. Sistēma tiek realizēta server puses javaskriptā (Node.js) hapi.js ietvarā, balstot…
Influence of sexual sensation seeking, sexual compulsivity and sexual pleasure in condom use among Spanish youth: implications for HIV interventions
2016
Spain is one of the countries with the highest incidence of HIV within the European Union. Multiple and complex factors influence HIV infection in young people. This study aims to determine the influence of sexual sensation seeking, sexual compulsivity and perceived sexual pleasure variables in condom use. A total of 424 heterosexual youth were evaluated (M age = 20.62; SD = 2.62) distributed into a risk group (60.7%) and a no-risk group (39.3%). Sexual Sensation Seeking Scale, AIDS Prevention Questionnaire, Sexual Compulsivity Scale, and Sexual Pleasure Perceived Scale were administered. Results indicate statistically significant differences in sexual sensation seeking (p=.001), failure to…
Extraordinary Performance of Carbon‐Coated Anatase TiO 2 as Sodium‐Ion Anode
2015
The synthesis of in situ polymer‐functionalized anatase TiO2 particles using an anchoring block copolymer with hydroxamate as coordinating species is reported, which yields nanoparticles (≈11 nm) in multigram scale. Thermal annealing converts the polymer brushes into a uniform and homogeneous carbon coating as proven by high resolution transmission electron microscopy and Raman spectroscopy. The strong impact of particle size as well as carbon coating on the electrochemical performance of anatase TiO2 is demonstrated. Downsizing the particles leads to higher reversible uptake/release of sodium cations per formula unit TiO2 (e.g., 0.72 eq. Na+ (11 nm) vs only 0.56 eq. Na+ (40 nm)) while the …
