ABSTRACT: The Tupinambá people have always had in their blood the striking feature to be warriors and used to delight themselves in battles since the arrival of the Europeans in their lands and the first conflicts stablished since then. As the years went by and with their geographical displacement due to the colonization of Brazil, the Tupinambás had to
restructure themselves as a tribe as well as their cultural formation, but they have not lost the warrior feature that is peculiar to them. This article aims to analyze how this striking feature of the Tupinambá culture has been preserved so far, from their religious education to the reasons why they used to fight.

No full textAnalysis and modeling of the behavior of hydrogels-based systems for biomedical and agro-food applications
No full text2015 - 2016Hydrogels are three-dimensional, hydrophilic, polymeric networks capable of imbibing large amounts of water or biological fluids. Depending on the type of polymer, number of cross-links, presence of ionic species the swelling/shrinking behavior can be greatly modified. This peculiar behavior, which has led to define this soft matter as “smart materials”, makes hydrogels and hydrogel-based systems very attractive by several frontier fields, such as biomedical applications, as well as for sectors that are less demanding technology, i.e. agro-food applications. The general aim of this Ph.D. thesis is to analyze, with ad hoc experiments, and to describe/simulate, through mathematical modeling, the behavior of hydrogels and hydrogel-based systems. A first question to answer when approaching hydrogels is: “are they multiphasic or monophasic systems”? The answer cannot be taken for granted. Despite in most experimental cases the response is simply avoided, it become fundamental when the aim is to develop a mechanistic mathematical model of the system. The most natural approach is to consider hydrogels as single-phase matter, in which several components can coexist, like it would be indisputably done for polymeric solutions (hydrosols). Another vision is to consider hydrogels as made of different phases, i.e. the water phase is separated from the polymeric phase, and these can exchange momentum. During this work a general modeling framework has been proposed to which several models from literature, multiphasic or monophasic, can be traced back or, vice versa, depending on the chosen approach the framework can be particularized to give the multiphasic or the monophasic balance equations. In this thesis, in light of its thermodynamic and numerical robustness, the monophasic approach, which is more consistent, has been chosen. Another important question is related to the need of modeling/analyze the full behavior, mass transport plus mechanics, or just one aspect, mass transport only. The difficulties related to the solution/analysis of the full hydrogels behavior have led many researchers to describe hydrogel-based systems with a “mass transport only” approach. This is, in example, common in drug delivery applications. During this PhD a mechanistic model based on a “mass transport only” approach for drug release from hydrogel-based system has been developed and validated against experimental data. HPMC-based tablets, loaded with Theophylline have been studied. Differently to what is normally done in dissolution tests, in this work besides the evaluation of the drug release via spectrophotometric analysis, the water and polymer residue have been determined by gravimetric analysis. This has been done on the entire tablets, as well as on portion of them, obtaining internal profiles of the components. The partially swollen tablets have been also subjected to indentation tests, which after an opportune calibration have allowed obtaining information on the water distribution inside the system. A 2Daxisymmetric model has been built on the water and drug mass transport equations; the polymer has been obtained from the mass fraction constraint. The deformations have been described with an ALE moving mesh method, whose boundaries move in relation to the amount of water and drug entering or leaving the system. The comparison between the detailed experimental results and the modeling results has shown a good agreement, in terms of masses, shape and components distribution, demonstrating that the main features had been correctly described. Such a formulated model has been applied to describe commercial-like tablets (in which excipients were present), with two type of HPMC with different substitution pattern (i.e. different degree of cross-links) and tested in non-standard apparatus (NMR cell). Despite after a proper tuning the model has been able to describe the drug and polymer release, the shape and the water distribution inside the system (experimentally taken from MRI technique) have not been correctly described. This application demonstrated the limits of a “mass transport only” approach. In the analyzed case the forces acting on the swelling tablet (shear, centrifugal, gravitational) could have a relevant impact, but most of all the different degree of cross-links of the HPMC played the major role.
In order to consider the hydrogel mechanics, the pure hydrogel behavior has been studied. Hydrogels normally couple solvent mass transport to system deformation and vice versa. This phenomenon is generally called poroelasticity and it is characteristic also of other materials (i.e. biological tissues, soils etc.). Another peculiarity of hydrogels is that the constituent polymeric network can have viscoelastic characteristics (i.e. like polymeric melts), which eventually translate in an overall hydrogel viscoelastic behavior. Depending on the time interval of interest and on the characteristic times of relaxation and diffusion, hydrogels can behave viscoelastically, poroelastically or poroviscoelastically (when the diffusion time is comparable with the relaxation time). A 3D model describing the poroviscoelastic behavior of hydrogels, still scarcely implemented in literature, has been developed within the field of non-equilibrium thermodynamics and non-linear solid mechanics (large deformations) and implemented in a commercial FEM-based software. The results of such kind of model permit to discriminate between and to study the poroelastic and viscoelastic regime as well as

it permits to study the poroviscoelastic behavior. Experimental unconfined stress-relaxation tests have been performed on agarose-gels at different concentrations with radius and height of 1 cm, and imposing a deformation of 10%. In the time range analyzed (1200 s) the agarose-gel has shown a predominant viscoelastic behavior, releasing only little amount of water. The model, after an initial tuning of the parameters, has been able to fairly predict the experimental data. Characteristic of the developed approach is that, once the model parameters are derived, it is possible to describe the hydrogel subjected to different stimuli (mechanicals or chemicals).
The proposed poroviscoelastic model is extendable to multicomponent diffusion systems, which could be, in example, controlled release systems based on hydrogels. For the first time, to the author’s knowledge, in the hydrogel-based systems modeling literature, in this thesis it has been shown how to extend the poroviscoelastic model to consider the presence of another diffusing species. The transport and constitutive model equations, opportunely modified, have been implemented in a commercial FEM-based software and, as an example, the drug release from a swelling system has been reported.

Successful practice in early career networks : Insights from the polar sciences
No full textAcquiring not only field-specific knowledge but also a set of transferable professional skills becomes increasingly important for Early Career Scientists (ECS) in Geosciences and other academic disciplines. Although the need for training in transferable skills adds to the work-load of an individual Early Career Scientist, it is often neglected within the traditional academic environments. International Early Career Networks (ECN) are global voluntary communities of early career scientists aiming (i) to advocate for early stage researchers; and (ii) to advance the careers of their members by raising their profiles and training them in specific transferable skills, such as networking, collaborating and outreach. Accordingly, ECN can be a tool to move beyond institutional barriers and to improve the inclusion of ECS into the international scientific community. In 2019 we conducted three surveys in order to assess ECN from the perspective of its members and regarding the structures of different ECN within a specific discipline and across disciplines. We use the survey results alongside with case studies from well-established and long term networks to elucidate the attributes that make a successful, sustainable ECN. Important characteristics of these international ECN include (1) developing the ECN organizational schemes to promote early career scientists within a specific discipline and across disciplines, (2) scoping for members needs, evaluating the performance of the network, and adapting to feedback, (3) continuity of the organizing committee by ensuring representation of different stages of ECS, and (4) diverse membership to provide strong foundational and personnel support within the network. These characteristics can support the development of best practices for developing ECN successfully, which can guide existing and future networks within Geosciences and other scientific disciplines. © Author(s) 2020.

Effects of alirocumab on cardiovascular and metabolic outcomes after acute coronary syndrome in patients with or without diabetes: a prespecified analysis of the ODYSSEY OUTCOMES randomised controlled trial
No full textBACKGROUND: After acute coronary syndrome, diabetes conveys an excess risk of ischaemic cardiovascular events. A reduction in mean LDL cholesterol to 1·4-1·8 mmol/L with ezetimibe or statins reduces cardiovascular events in patients with an acute coronary syndrome and diabetes. However, the efficacy and safety of further reduction in LDL cholesterol with an inhibitor of proprotein convertase subtilisin/kexin type 9 (PCSK9) after acute coronary syndrome is unknown. We aimed to explore this issue in a prespecified analysis of the ODYSSEY OUTCOMES trial of the PCSK9 inhibitor alirocumab, assessing its effects on cardiovascular outcomes by baseline glycaemic status, while also assessing its effects on glycaemic measures including risk of new-onset diabetes. METHODS: ODYSSEY OUTCOMES was a randomised, double-blind, placebo-controlled trial, done at 1315 sites in 57 countries, that compared alirocumab with placebo in patients who had been admitted to hospital with an acute coronary syndrome (myocardial infarction or unstable angina) 1-12 months before randomisation and who had raised concentrations of atherogenic lipoproteins despite use of high-intensity statins. Patients were randomly assigned (1:1) to receive alirocumab or placebo every 2 weeks; randomisation was stratified by country and was done centrally with an interactive voice-response or web-response system. Alirocumab was titrated to target LDL cholesterol concentrations of 0·65-1·30 mmol/L. In this prespecified analysis, we investigated the effect of alirocumab on cardiovascular events by glycaemic status at baseline (diabetes, prediabetes, or normoglycaemia)-defined on the basis of patient history, review of medical records, or baseline HbA1c or fasting serum glucose-and risk of new-onset diabetes among those without diabetes at baseline. The primary endpoint was a composite of death from coronary heart disease, non-fatal myocardial infarction, fatal or non-fatal ischaemic stroke, or unstable angina requiring hospital admission. ODYSSEY OUTCOMES is registered with ClinicalTrials.gov, number NCT01663402. FINDINGS: At study baseline, 5444 patients (28·8%) had diabetes, 8246 (43·6%) had prediabetes, and 5234 (27·7%) had normoglycaemia. There were no significant differences across glycaemic categories in median LDL cholesterol at baseline (2·20-2·28 mmol/L), after 4 months' treatment with alirocumab (0·80 mmol/L), or after 4 months' treatment with placebo (2·25-2·28 mmol/L). In the placebo group, the incidence of the primary endpoint over a median of 2·8 years was greater in patients with diabetes (16·4%) than in those with prediabetes (9·2%) or normoglycaemia (8·5%); hazard ratio (HR) for diabetes versus normoglycaemia 2·09 (95% CI 1·78-2·46, p<0·0001) and for diabetes versus prediabetes 1·90 (1·65-2·17, p<0·0001). Alirocumab resulted in similar relative reductions in the incidence of the primary endpoint in each glycaemic category, but a greater absolute reduction in the incidence of the primary endpoint in patients with diabetes (2·3%, 95% CI 0·4 to 4·2) than in those with prediabetes (1·2%, 0·0 to 2·4) or normoglycaemia (1·2%, -0·3 to 2·7; absolute risk reduction pinteraction=0·0019). Among patients without diabetes at baseline, 676 (10·1%) developed diabetes in the placebo group, compared with 648 (9·6%) in the alirocumab group; alirocumab did not increase the risk of new-onset diabetes (HR 1·00, 95% CI 0·89-1·11). HRs were 0·97 (95% CI 0·87-1·09) for patients with prediabetes and 1·30 (95% CI 0·93-1·81) for those with normoglycaemia (pinteraction=0·11). INTERPRETATION: After a recent acute coronary syndrome, alirocumab treatment targeting an LDL cholesterol concentration of 0·65-1·30 mmol/L produced about twice the absolute reduction in cardiovascular events among patients with diabetes as in those without diabetes. Alirocumab treatment did not increase the risk of new-onset diabetes. FUNDING: Sanofi and Regeneron Pharmaceuticals.sponsorship: Sanofi and Regeneron Pharmaceuticals.
