Study on correlation between motor and memory learning
No full textThe Knowledge of the Result for motor learning, relationship between subjective estimation of the error and relative frequency of external feedback. Research on the learning of a motor task, although generally conducted on healthy individuals, can offer useful indications about the best strategies to be adopted in the rehabilitation of subjects with CNS lesions. In fact, rehabilitation can be considered as a learning process in pathological conditions. There are numerous experimental evidences that, a lower relative frequency (FR) with which it is provided to the one who learns the knowledge of the result (CR) about the outcome of the response, and the request of the formulation of a subjective estimate before the CR (SS) both positively affect the fixation of the motor task. Recently, however, the possibility of an interaction between these two variables has been suggested, in the sense that the subject, when he must formulate a subjective estimate of the error, would benefit from a greater, and not a lesser, FR. To verify this, 60 healthy young subjects (mean age 24.1 ± 3.2) performed a simple task of producing a concentric work target with flexed elbow muscles during isokinetic contraction at a rate of 30 degrees / second. During the practice trials, subjects a) were required, or were not required, to estimate the error made in the newly concluded trial, and b) CR was provided after each trial (100% FR) or after one in every five trials (20 % FR). To further stress the difference between the subjects who were or should not formulate an SS, the latter was asked, immediately after the conclusion of the trial, to perform a simple mental calculation. All subjects performed 15 sets of 10 repetitions of the task during a single practice session. A retention test (1 set of 10 repetitions without CR or SS) was performed the following day. The comparison between the groups in the retention test was performed with the analysis of the variance, before and after adjustment for the initial conditions. The results showed that, after adjusting for the initial conditions, the group of subjects who received CR with 100% FR and who had to formulate the SS during the practice period, performed the retention test in a significantly better way
Review on study of sporting activity for the reaches school learning
No full textThe threshold of attention is valid for all types of contexts that the child faces from an early age, one of these is their academic performance that often, due to the inability to concentrate, is scarce and obstacle to the relationship between problematic child and his peers and adults. No responsibility is ascribable to children because, certainly, they are suffering from a neuropsychological disorder, nor are they the parents' fault. The pathology that has found space is ADHD (attention deficit and hyperactivity disorder: attention deficit and hyperactivity). It is one of the most frequent neuropsychological disorders of the developmental age, which occurs in pediatric age, characterized by a level of inattention and by a series of secondary seconds that denote hyperactivity and impulsivity. Children with ADHD cannot control their responses to the environment: they are inattentive, hyperactive and impulsive. Such behavior compromises their social and educational life. This pathology is associated, in fact, with disorders of social adaptation, a low level of education and employment, to be considered one of the most important signs, in childhood, of bad psychosocial adaptation in adulthood. The ADHD is too often misunderstood therefore not considered supported by therapeutic interventions. So, the aim of this research in to promote an educational and therapeutic path based on the increase of the hours of sport and motor education (in the extracurricular context) with the aim of improving the attention span, reducing impulsive problems, hyperactivity and stimulating self-control

No full textDisastri lenti agroalimentari e divenire dei mondi rurali. Un’introduzione alla special issue = Slow agri-food disasters and the becoming of rural worlds. An Introduction to the Special Issue
No full textSlow agrifood disasters and rural becomings. An introduction to the special issue
The article introduces the concept of slow agrifood disasters as a critical lens to investigate contemporary forms of ecological and social vulnerability in rural worlds, with a focus on the Mediterranean area. Drawing on empirical cases from Morocco, Italy, and France, the special issue shows how the productivist and industrial organization of agri-food systems not only fails to prevent disasters but often constitutes one of their main direct or indirect causes. The concept of slow disaster enables the analysis of these processes across multiple scales and over extended temporalities, revealing how the accumulation of ecological, health, and social damages is often normalized. Within this framework, the notion of rural becomings shifts the focus away from static representations of rurality toward an understanding of rural worlds as dynamic realities, shaped by socio-ecological tensions, multispecies relationships, and conflicts between divergent agricultural models where disaster can – though rarely does – become an opportunity of transformation toward agroecology. The ethnographic and multispecies approaches adopted in the articles of the special issue highlight the complex relations between agriculture, ecology, institutions, and social subjectivities, questioning technocratic and financial responses to risk. Finally, the dialogue between agri-food studies and disaster studies suggests new theoretical and methodological pathways for understanding and engaging with contemporary rural territories

Text:
Melanoma diagnoses have risen sharply over past decades, and despite new lines of therapy have been introduced the need for additional drugs is urgent. Previous findings from our group demonstrated that climacostol, an alkyl resorcinol produced by the ciliated protozoan Climacostomum virens, decreases the viability of five different mammalian cancer cell lines, while it was devoid of effects on endothelial cells. In order to expand these data and due to the availability of the synthetic toxin, we have further analysed different tumoral and non-tumoral cell lines, observing that viability of human and rodent tumoral cells was negatively affected by climacostol with higher potency when compared to non-tumoral cells. We then focused on the B16-F10 mouse melanoma cells, where climacostol caused a concentration-dependent reduction of viability with an EC50 of 6.3 μg/ml, and an Emax of 30 μg/ml. Flow cytometry analyses indicated that cell proliferation was effectively inhibited by climacostol, with a significant increase of apoptotic cells.The data collected prompted us to investigate the effects of climacostol on in vivo melanoma progression using a B16-F10 allograft transplantation tumor model. The results indicate that climacostol decreased tumour weight and increased the content of apoptotic cells, suggesting that the toxin may be considered for the design of cytotoxic and pro-apoptotic new drugs for melanoma therapy
