Full text linkEffects of metabolic training in type 2 diabetes patients
No full textObjective: give a type of physical exercise that increases the sensitivity to insulin and improves the following parameters: Glycated Hemoglobin (HbA1c), Body Mass Index (BMI), Maximum Ozygen Consumption (VO2max) and Body weight. Methods: a group of type 2 diabetes patients (6 males and 5 females) in care at INRCA-IRCCS Hospital of Ancona - U.O.C. Diabetes and Metabolic Diseases sono stati sottoposti ad un combination of aerobic and resistance training for a period of 12 weeks. Results: it was pointed out a reduction, no statistically significant (p>0.05), of the HbA1c (-2.8%), BMI (-0.9%), Body weight (-1.9%) values. It has been recorded a statistically significant increase (p<0.05) of VO2max values (5.5%). Conclusion: the combination training è un metodo di allenamento efficace per il trattamento del diabete di tipo 2
EDUCAZIONE MOTORIA E MIGLIORAMENTO DELLA DISPONIBILITÀ ATTENTIVA IN ETÀ EVOLUTIVA
Full text linkL’Obbiettivo del presente lavoro è di verificare l’ipotesi secondo la quale una seduta psicomotoria condotta prima di un compito didattico (nel caso lo svolgimento di un dettato), possa incrementare la disponibilità attentiva in alunni di età compresa tra i 7 e gli 8 anni e la qualità del risultato al compito stesso. A tal fine sono stati coinvolti 170 alunni, ai quali si sono somministrati due diversi tipi di intervento: una prova di dettato (D) e una prova di dettato preceduta da una seduta di ginnastica (Ex+D). Successivamente, si è proceduto al calcolo degli errori compiuti nelle diverse prove e alle verifiche statistiche.
Dall’analisi dei dati è emerso che la MEDIA degli errori compiuti nei dettati è inferiore e statisticamente significativa (p<0.0005) quando questi sono preceduti da una seduta di ginnastica psicomotoria rispetto a quando effettuati senza alcun intervento.
In conclusione si è osservato che la pratica psicomotoria è da considerarsi, a tutti gli effetti, una buona opportunità per stimolare la disponibilità attentiva e migliorare le prestazioni didattiche e ciò ci fa pronunciare, senza indugio, l’esortazione affinché essa possa divenire prassi consueta in ambiente scolastico
Radon and Building: preventive action for risk reduction.
No full textThe World Health Organization identifies radon as the second cause of lung cancer in the general population, after smoking. Epidemiological studies have provided convincing evidence of an association between indoor radon exposure and lung cancer, even at the relatively low radon levels commonly found in residential buildings.
Radon is a natural gas produced from uranium and thorium decay; soil is generally the main source of radon accumulating in indoor environment. Thus the knowledge of gas potential release from soil
is a powerful tool to make new buildings with low level of indoor radon: a preventive action with a specific field survey can be more effective and economic if compared with later mitigation practices.
The knowledge of potential radon emission from soil can have different addresses according to the investigation scale. If applied to large scale survey, it can provide useful data for urban planning and lead to a territory zoning, with location of areas where a significant proportion of homes exceed the reference level (radon-prone areas). In case of small scale investigation (construction site scale), it is possible to collect more detailed information on potential radon release from soil. Here, a protocol for the evaluation of radon hazard factor is proposed in order to promote a practical approach to exploit in any single construction site. This protocol provides a set of indications whose core is the contemporaneous measurements of soil radon concentration and intrinsic permeability. Using these two parameters, a numerical index is calculated, whose value allows to characterise the site on the basis of hazard classes. Mapping soil radon and radon hazard can be a further investigation tool, useful to define the spatial distribution of parameters. Furthermore, the protocol provides suggestions on the protection degree of a new building, in terms of proper construction techniques to prevent gas transport from the soil to the indoor environment. It also gives indication on the permeability features of the ground surrounding the building with the aim of preventing a focused radon flow towards the building foundations.
It is important to keep in mind that different methods can be used to measure the parameters. Consequently, it is useful and necessary to validate the method through intercomparison exercises in test-sites. Caffarella Valley (Rome) represents a well-consolidated reference site to study soil radon variability and intercomparison work took place there. Actually, this kind of events are regularly organised in different European countries with the participation of universities, research centres and private firms
Orienting movements in area 9 identified by long-train ICMS
No full textThe effect of intracortical microstimulation has been studied in several cortical areas from motor to sensory areas. The frontal pole has received particular attention, and several microstimulation studies have been conducted in the frontal eye field, supplementary eye field, and the premotor ear–eye field, but no microstimulation studies concerning area 9 are currently available in the literature. In the present study, to fill up this gap, electrical microstimulation was applied to area 9 in two macaque monkeys using long-train pulses of 500–700–800 and 1,000 ms, during two different experimental conditions: a spontaneous condition, while the animals were not actively fixating on a visual target, and during a visual fixation task. In these experiments, we identified backward ear movements, goal-directed eye movements, and the development of head forces. Kinematic parameters for ear and eye movements overlapped in the spontaneous condition, but they were different during the visual fixation task. In this condition, ear and eye kinematics have an opposite behavior: movement amplitude, duration, and maximal and mean velocities increase during a visual fixation task for the ear, while they decrease for the eye. Therefore, a top-down visual attention engagement could modify the kinematic parameters for these two effectors. Stimulation with the longest train durations, i.e., 800/1,000 ms, evokes not only the highest eye amplitude, but also a significant development of head forces. In this research article, we propose a new vision of the frontal oculomotor fields, speculating a role for area 9 in the control of goal-directed orienting behaviors and gaze shift control
Changes in reach-to-grasp behaviour over the course of training in rats
No full textOne complex task involving sequence of movements and movement refinement in the rat is the single-pellet reaching task, comprising orientation, transport and withdrawal in sequence. In turn, orientation comprises front wall detection, slot localization and nose poke until reach start. Video recordings of a rat in the reaching box highlighted three stages of temporal training: start of training (ST), forepaw dominance appearance (D) and fully trained (T). Regarding orientation, ST versus D and T presented a significant smaller frequency of approach to the front wall and a significant higher number of whisker cycles and nose touches during slot localization, involving a significant longer Orientation. At the ST stage, 44% of the trials were interrupted after nose poke, and poke took place at significant higher level from the shelf. The shelf was identified only when short whiskers contacted it, but the tongue and both forepaws were used without distinction to reach and grasp the pellet until a forepaw emerged as dominant at D stage. Regarding the temporal features of transport and withdrawal, comparing the D versus T stage revealed a significant longer duration. Finally, successes were significantly higher in T respect to D, meaning that after dominance emergence, more training was still necessary to improve reaching/grasping performance. This study provides evidence that, during training, the rats develop a strategy to obtain the pellets and then refine their movement pattern
