Buena fe y confianza

Il principio di affidamento legittimo, pur ritornato in auge in molti sistemi giuridici europei, compresa la Francia, non brilla per chiarezza. Lo studio intende perciò ripercorrere sinteticamente le origini storiche del principio per definirne i contenuti, per poi seguire una prima linea di analisi, secondo la quale l’utilità di questo principio ordinante non è solo didattica o politica, ma diventa criterio interpretativo per riconoscere una responsabilità di natura contrattuale in taluni casi difficili, che riguardano prevalentemente l’efficacia del contratto nei confronti dei terzi. Una seconda linea di analisi mira, invece, a dimostrare che il principio di affidamento legittimo può incarnarsi in regola, così riacquistando un’utilità quale fonte autonoma di obbligazioni di natura contrattuale

On the gradient rearrangement of functions

In this paper, we introduce a symmetrization technique for the gradient of a \BV function, which separates its absolutely continuous part from its singular part (sum of the jump and the Cantorian part). In particular, we prove an \text{\emph{L}}^{\text{1}} comparison between the function and its symmetrized. Furthermore, we apply this result to obtain Saint-Venant type inequalities for some geometric functionals

Physical activity, nutrition and bone health

This review aims to describe the roles that physical activity and nutrition have in bone metabolism and to examine their effects on bone in a situation of altered metabolism as a consequence of inadequate nutrition and/or excessive physical activity. Referring to the recent studies and the main guidelines in the literature on athlete nutrition, the paper also focuses on essential nutrients for bone health during performance. Finally, it discusses the negative effect of some nutrients on bone mineral density

Dare to jump: The effect of the new high impact activity SuperJump on bone remodeling. A new tool to maintain fitness during COVID-19 home confinement

SuperJump is a high impact activity performed on an elastic trampoline that mixes aerobic and anaerobic exercises already proposed as home-based activity for preventing a sedentary lifestyle. We determined in a randomized controlled trial whether 20 weeks of SuperJump activity would promote bone formation and reduce resorption in eumenorrheic women. Twenty-four women were randomized to a non-exercise group (control group) or an exercise group that performed SuperJump activity three times a week for 20 weeks. Blood samples were collected in both groups at baseline and at the end of the 20 weeks and compared within and between the groups for C-terminal telopeptide (CTX), a marker of bone resorption, osteocalcin, a marker of bone formation, and the markers of bone metabolism parathyroid hormone (PTH), calcitonin, albumin-adjusted calcium (Aa calcium), vitamin D, phosphate and potassium. After 20 weeks of SuperJump activity, levels of CTX were significantly reduced while levels of osteocalcin were increased. PTH, calcium and potassium were involved in the mechanism of action because PTH was reduced while calcium and potassium were increased. Calcitonin, vitamin D and phosphate levels did not change. These data suggest that SuperJump activity is able to reduce bone resorption and improve bone formation by acting on essential regulators of bone metabolism. They also suggest that SuperJump training may be used as a valuable intervention to prevent the occurrence of osteoporosis in aging because it improves bone homeostasis in favor of bone formation and could counteract a sedentary lifestyle, such as during COVID-19 home confinement, which could itself contribute to the variation of bone metabolism.

Information and Impression Regarding ASD Questionnaire Answered by Foreigners Living in Brazil

Autism Spectrum Disorders (ASDs) constitute a group of disorders characterized by changes present at early ages and manifesting in the areas of development of communication, behavior, and interpersonal relationship. Because ASD significantly affects communication and the social skills, all multicultural context needs to be better investigated. There is an urgent need to understand the impact of migratory process, bilingual environment exposure on the language development of children with ASD. The present study aims to present the results of 657 foreign residents in Brazil that answered an online questionnaire to know the consolidated information about ASD. Participants from 23 countries responded to the survey. Bolivia and Argentina were the countries with the highest number of participants. The present study found that 100% of the participants have heard of autism. About 80.6% of the sample had a family member with autism. The sociodemographic diversity identified in this study reflects the sociocultural diversity present in Brazil, besides reinforcing the importance of considering this population when thinking about strategies and behaviors directed at individuals with ASD

Effects of water and CMA in mitigating industrial road dust resuspension

Water spraying and/or chemical suppressants such as salts and polymers have been suggested to reduce road dust resuspension due to their capability to increase adhesion, and therefore the effective size and weight of particles, but contrasting results have been obtained so further testing are needed. This study presents the first results of street washing and Calcium Magnesium Acetate (CMA) efficiencies at two industrial roads (paved and unpaved) in the Mediterranean region where the high solar radiation, warm climate, and scarce precipitation, may play a key role in determining the efficiency of mitigation techniques Results show that, at both sites, street washing (water only) was more effective than CMA. Street washing made observe 18% (daily basis) and >90% (first hour) reductions of kerbside PM10 concentrations for the paved and unpaved road respectively, while with CMA PM10 decrease was generally lower and with less statistical significance.his work was funded by AIRUSE LIFE+ ENV/ES/584 project.

Alteration of the Growth Hormone Axis, Visceral Fat Dysfunction and Early Cardiometabolic Risk in Adults: The Role of The Visceral Adiposity Index

The aim of the study is to clarify the relationship between adipose tissue dysfunction, metabolic profile and growth hormone (GH)/insulin-like growth factor (IGF)-I secretion in healthy adult subjects. We investigated the metabolic profile in a cohort of 231 consecutive healthy subjects in relation to GH, IGF-I levels, and visceral adiposity index (VAI). Anthropometric measures, lipid profile, and glucose and insulin levels during oral glucose tolerance test, Homa-IR and ISI Matsuda, IGF-I and GH peak after GHRH plus Arginine test were analyzed. The subjects with high VAI showed lower GH peak (22.8 ± 11.1 vs. 42.2 ± 21.3 µg/L; p = 0.049) and lower IGF-I (presented as IGF-I under normal range, UNR) (0.54 ± 0.14 vs. 0.64 ± 0.12; p = 0.005) than group with normal VAI. ROC curve analysis identified the cut-off, able to detect subjects with high VAI, i.e., 31.8 µg/L for GH peak and 0.63 for IGF-1 UNR. The subjects with GH peak and IGF-I UNR under the cut-off showed significantly higher levels of VAI, systolic and diastolic blood pressure, glucose and insulin levels, Homa-IR, and lower ISI Matsuda, with a concomitant worse lipid profile (all p < 0.001). A strong relationship between GH axis, VAI and metabolic risk has been demonstrated. A percentage of apparently healthy subjects show a degree of visceral adipose dysfunction associated with GH and IGF-I levels that do not meet the criteria of overt GH deficiency (GHD). Long-term prospective studies could help to clarify and confirm whether a hypothetical condition of subclinical GHD could be taken into account as a new clinical entity
