Porto Ercole l'ultima dimora di Caravaggio
No full textil volume, ricco di fotografie e corredato di un DVD, indaga sugli ultimi giorni di vita di Caravaggio e sugli spostamenti immediatamente precedenti alla sua morte. Avvalendosi della recente scoperta dei resti del Caravaggio tramite le analisi del DNA e dell'ausilio storico di studiosi locali, gli Autori ricostruiscono gli ultimi momenti di vita del grande e controverso pittore a Porto Ercol
Ricostruzione virtuale 3D di una clavicola frammentata
No full textThe work presents a methodology for the virtual reconstruction of broken human bones coming from archaeological contexts and useful even for surgical purposes. The case report involves the reconstruction of a left incomplete clavicle considering the opposite right one.
The methodology consists of virtual acquisition of the two-pieces broken left clavicle and of the right integer one by means of a 3D laser scanner, using the 3D mirrored model of the last one as reference model to reconstruct the left clavicle. Three grids characterized by an increasing number of homologous landmarks are identified on both the 3D meshes and are used to perform the warping process.
The three digital reconstructed models provide a reliable correspondence with the left clavicle original one, highlighting indeed that an increased number of landmarks do not improve the final result
Obesity and blood pressure in children
No full textEstimates of relationships between blood pressures and anthropometric structure or body composition were made on a total sample of 414 children, taking age and sex into account. A subsample of 250 children was formed from obese (or slightly obese) subjects. A different pattern in anthropometric structure and body composition resulted in relation to a different degree of obesity. A canonical correlation analysis was carried out for each sex, in which a multivariate measure of the linear association between heart-circulatory functionality parameters, on the one hand, and all the anthropometric traits and body composition parameters, on the other, was computed. This association resulted statistically significant in both sexes, also if a difference was observed as concerns the traits that most heavily contributed to the relationships between sets of variables, with an evident sexual dimorphism also in infancy. The necessity of preventive measures and sanitary screening also during infancy ..
Il ritrovamento della tomba e la identificazone dei resti di Matteo Maria Boiardo nella chiesa di Santa Maria di Scandiano (Reggio Emilia)
No full textIn base alle informazioni documentali e alle prospezioni con il georadar, sotto il pavimento della chiesa di S. Maria di Scandiano (R.E.), sono state localizzate le cripte sepolcrali nelle quali dovevano aver trovato sepoltura il poeta Matteo Maria Boiardo e alcuni membri della sua famiglia, fra cui il padre Giovanni e il nonno Feltrino, oltre forse alla moglie Taddea Gonzaga e ad uno dei figli, Camillo. L’esplorazione delle cripte sepolcrali ha consentito di recuperare resti scheletrici attribuibili complessivamente a non meno di 20 individui tra adulti e infanti, di cui 3 rinvenuti in una camera sepolcrale e i restanti in una tomba attigua. Fra i primi è stato identificato un individuo pienamente compatibile quanto a sesso, età di morte, robustezza corporea e statura con le caratteristiche fisiche del poeta Boiardo. A conferma della sua probabile identità, il profilo genetico di questo individuo, ottenuto dal DNA nucleare estratto dai suoi resti, si è rivelato compatibile secondo un possibile rapporto parentale figlio/padre con quello ottenuto da un reperto rinvenuto nella camera attigua che doveva ospitare il padre e il nonno del poeta. Nei resti di un secondo individuo, di sesso femminile e di età avanzata, con profilo genetico estraneo ai precedenti, potrebbe identificarsi la moglie del Boiardo. Quanto ai resti del terzo individuo, pur non potendo escludere trattarsi di Camillo, figlio del poeta morto in giovane età, non è stato per il momento possibile raccogliere prove che confermino questa ipotesi
Evaluating humeral bilateral asymmetry by means of a virtual 3D approach
No full textWe describe a new methodology for the evaluation of bilateral asymmetry in the humerus. It consists of the virtual comparison of three-dimensional (3D) digital models of the right and left humeri of one individual from the Middle Ages. The 3D geometric models, obtained using a NextEngine laser scanner, were oriented in PolyWorks® 10.1. In the same software, a mirror image of the left humerus was produced. Proximal and distal epiphyses of the oriented humeri were cut at the 15% and 85% points of the humerus’ physiological length in order to individually compare the three obtained parts (proximal epiphysis, distal epiphysis and diaphysis). The epiphyses were directly superimposed and the deviation quantified by inspection analysis. For the diaphysis, the best fit cylinder of the mirrored left humerus was created and used as a reference shape for the inspection analysis. The inspection analysis allows us to identify the areas where the two humeri differ morphometrically and to quantify the differences with high precision

Skinfolds and body composition of sports participants
No full textBody composition of 1815 North-Italian young sports participants in relation to sex, age, sport and level of performance was investigated. About thickness and anatomical distribution of subcutaneous fat females showed skinfolds thicker than males. Significant differences were observed in skinfold thicknesses means of different sport-groups. Subscapular and forearm skinfolds were the best discriminant variables for males and females respectively. Body density was estimated according to Katch and McArdle (1973) and Durnin and Womersley (1974) equations. Males showed higher body density and lower fat percentage values than females. The lowest value of body density and the highest fat percentage were in male martial art competitors and in females practising skating and athletics. The highest values of body density and the lowest of fat percentage were in males practising athletics and rowing and in female martial art competitors. Highest and lowest values of fat-free mass were in games players and in soccer players and gymnasts respectively. "High aptitude" subjects showed higher fat-free mass values than "middle aptitude" group, besides a tendency towards higher body density values and lower fat percentage than "middle aptitude" group. With aging body density decreased whereas fat percentage and fat-free mass increased
Stable isotope and in situ trace element analyses on human bone tissue (Roccapelago, 16th-18th cent.): preliminary inferences on diachronic change in eating habits and trace element reliability
No full textWe measured trace elements and stable isotopes (C and N on collagen) on 19 samples, taken from different anatomical area of 7 individuals from the medieval site of Roccapelago (Modena): our attempt is to reconstruct the diet of these individuals and discuss the role of trace elements in palaeodiet. The good preservation of these bodies represents a unique chance to work on likely diagenesis-free archaeological human remains, to test the trustworthiness of trace element analyses. In fact, in the last decades, trace element reliability was questioned several times. We particularly focus our attention on magnesium, strontium and zinc. Our data set shows different eating habits for the studied individuals. While collagen of the samples dated at 16th century yields typical values of a C3-plant based diet, collagen of samples dated at 18th cent yields higher values of both δ13C and δ15N, probably linked to an higher trophic level and to a shift toward a C4-environment. Similarly, Sr and Mg show the same increment in individuals of 18th cent, while Zn does not show any significant variation. The latter is quite discussed in the scientific literature and has been commonly used as a marker for a protein-rich diet. Our lack of correlation between Zn and stable isotopes (especially N) confirms the uselessness of this element in palaeodiet reconstruction. Geochemical data are also corroborated by the botanical evidence of maize presence (C4 plant) and by historical sources that attest the presence of maize in Emilia-Romagna during 18th century
