Cortisol claws concentrations in dogs from birth to 60 days of age
Jasmine Fusi, Tanja Peric, Barbara Bolis, Alessandro Rota, Antonella Comin, Maria Cristina Veronesi, 2017, objavljeni povzetek znanstvenega prispevka na konferenci

Opis: During the last fetal stage of development and in the neonatal period, the hypothalamic- pituitary- adrenal (HPA) axis secretes cortisol (C), responsible for several physiologic processes. The claws were recently proved to be a useful, non- invasive matrix for long time- frame retrospective C levels analysis also in puppies (Veronesi et al. 2015, Theriogenology 84:791–796). Because of the scarce knowledge on canine perinatology, this study was aimed to assess the C concentrations in claws of newborn puppies collected at birth, 30 and 60 days of age, and to evaluate the possible influence of age, gender and type of birth on C claws accumulation. The study was performed on 58 large purebred, normal, healthy puppies, born by spontaneous or cesarean parturition. The mean C claws concentrations significantly decrease from birth (26 ± 16.39 pg/mg) to 30 (10 ± 4.53 pg/mg) and 60 (6 ± 3.12 pg/mg) days of age (p < 0.0001); a decrease was also seen from 30 to 60 days of age (p < 0.05). No influence of newborn gender and type of birth was found. This trend of decrease is in agreement with data reported by (Veronesi et al. 2015, Theriogenology 84:791–796) in dead puppies, and suggests the important role of C around the time of birth. However the exact source of the C accumulated in claws of puppies at birth must be clarified, while the source of C accumulated at 30, and even more at 60 days, can be supposed to be addressed to the newborn itself.

Opis: The report consist of individual test-run reports by participating teachers and consortium-level observers that gathered qualitative and quantitative data through short interviews, surveys and QA questionnaires mostly with students, but also among themselves. A joint evaluation is delivered and a “lessons learned” compendium published, offered digitally through the project’s dissemination system (mostly newsletter and website-promotion), and spread locally through the teaching communities – also partly entering the professional article as “experience report” (see next deliverable). These reports and the “lessons learned” were discussed and confirmed in the below structure at the September 2013 meeting, organised by P4. Notably, a total of three sceintific or porfessional articles were (to be) published (as separate deliverables) refereing to the lessons learned in this project, refering to the summative experience of the project.

Packing patterns of silica nanoparticles on surfaces of armored polystyrene latex particles
Sara Fortuna, Catheline A. L. Colard, Stefan A. F. Bon, Alessandro Troisi, 2009, izvirni znanstveni članek

Opis: Fascinating packing patterns of identical spherical and discotic objects on curved surfaces occur readily in nature and science. Examples include C60 fullerenes,(1, 2)13-atom cuboctahedral metal clusters,(3) and S-layer proteins on outer cell membranes.(4) Numerous situations with surface-arranged objects of variable size also exist, such as the lenses on insect eyes, biomineralized shells on coccolithophorids,(5) and solid-stabilized emulsion droplets(6) and bubbles.(7) The influence of size variations on these packing patterns, however, is studied sparsely. Here we investigate the packing of nanosized silica particles on the surface of polystyrene latex particles fabricated by Pickering miniemulsion polymerization of submicrometer-sized armored monomer droplets. We are able to rationalize the experimental morphology and the nearest-neighbor distribution with the help of Monte Carlo simulations. We show that broadening of the nanoparticle size distribution has pronounced effects on the self-assembled equilibrium packing structures, with original 12-point dislocations or grain-boundary scars gradually fading out.

An artificial intelligence approach for modeling molecular self-assembly: Agent Based simulations of rigid molecules
Sara Fortuna, Alessandro Troisi, 2009, izvirni znanstveni članek

Opis: Agent-based simulations are rule-based models traditionally used for the simulations of complex systems. In this paper, an algorithm based on the concept of agent-based simulations is developed to predict the lowest energy packing of a set of identical rigid molecules. The agents are identified with rigid portions of the system under investigation, and they evolve following a set of rules designed to drive the system toward the lowest energy minimum. The algorithm is compared with a conventional Metropolis Monte Carlo algorithm, and it is applied on a large set of representative models of molecules. For all the systems studied, the agent-based method consistently finds a significantly lower energy minima than the Monte Carlo algorithm because the system evolution includes elements of adaptation (new configurations induce new types of moves) and learning (past successful choices are repeated).

Hexagonal lattice model of the patterns formed by hydrogen-bonded molecules on the surface
Sara Fortuna, David L. Cheung, Alessandro Troisi, 2010, izvirni znanstveni članek

Opis: We model the two-dimensional self-assembly of planar molecules capable of complementary interactions (like hydrogen bonding) as a set of hexagonal tiles on a hexagonal lattice. We use Monte Carlo simulations to study the phase diagrams of three model systems. The phases are characterized using a variety of order parameters, and they are studied as a function of the strength of the complementary interaction energy. This simplified model is proven to be capable of reproducing the phases encountered in real systems, unifying within the same framework most of the structures encountered experimentally.

Agent based modelling for the 2D molecular self-organization of realistic molecules
Sara Fortuna, Alessandro Troisi, 2010, izvirni znanstveni članek

Opis: We extend our previously developed agent-based (AB) algorithm to the study of the self-assembly of a fully atomistic model of experimental interest. We study the 2D self-assembly of a rigid organic molecule (1,4-benzene-dicarboxylic acid or TPA), comparing the AB results with Monte Carlo (MC) and MC simulated annealing, a technique traditionally used to solve the global minimization problem. The AB algorithm gives a lower energy configuration in the same simulation time than both of the MC simulation techniques. We also show how the AB algorithm can be used as a part of the protocol to calculate the phase diagram with less computational effort than standard techniques.
