No full textIntroduction: The aim of the study was to investigate the influence of training
status on cardiovascular function in young male recreational and competitive
rowers.
Methods: Ejection duration in percentage to the heart rate period (ED%),
subendocardial viability ratio (SEVR), augmentation index at 75 bpm (AIx75) and
carotid to femoral pulse wave velocity (cf-PWV) of competitive rowers (CR) (age
17.6 ± 4.1 years), recreational rowers (RR) (age 16.7 ± 2.70 years) and athletes
practicing other recreational sports (ORS) (age 15.3 ± 1.4 years) were assessed.
Results: ED% was lower in CR compared to ORS (31.9 ± 3.9% vs. 38.4 ± 4.8%; p =
0.026) and cf-PWV was higher in CR compared to ORS (5.5 ± 1.0 m/s vs. 4.7 ±
0.5 m/s; p = 0.032). SEVR was higher in CR compared to RR and ORS (165.8 ±
33.7% vs. 127.4 ± 30.4% and 128.3 ± 27.8%; p = 0.022) and AIx75 was lower in CR
compared to RR and ORS (−15.7 ± 8.6% vs. 1.2 ± 9.9% and 1.5 ± 9.1; p = 0.001).
Discussion: Healthy, young competitive male rowers reported higher myocardial
performance and better cardiovascular health than recreational athletes.
Interpretations of cf-PWV in competitive rowers should be performed alongside
other cardiovascular indicators
Effect of LNA integration on endocrine and metabolic parameters in dairy cattle
No full textIn a field trial the effect of long term supplementation of different levels of estruded linssed and energy levels on milk yeld and plasma concentrations of insulin, T3,cortisol, leptin, glucose and non esterified fatty acids (NEFA) in dairy cow in early lactation, were evaluated. Fifth seven italian holstein fresian cows reared in Parmigiano Reggiano cheese area, homogeneous for lactation number, days in miilkings (DIM) (41±12d), BCS (3.17±0.14) in productive level in the previous lactations, were allotted into three experimental groups, in different farms, with similar management system (Control group - C 1.45 Mcal NEI/Kg DM, 280 g/d Omega-Lin® - Mignini &Petrini 0280; 1.51 Mcal NEI/Kg DM, 450 g/d Omega-Lin® - Mignini &Petrini 0450; 1.56 Mcal NEI/Kg DM) and feed isonitrogenous TMR diets. Omega-Lin® contained 70% of exstruded linseed. Blood samples were taken by coccigeal vein and blood parameters evaluated. Fixed effect of diet, parity and hear within diet were tested. Parity showed a significant effect only for milk yeld and T3, while diet influenced significantly milk yield, T3, leptin and NEFA. Milk yield was higher in 0450 group compared to the control one (43.61 vs 35.51: P<0.01). T3 showed the highest level in 0450 group if compared with C group (1.32 nmol/l vs 1.07 nmol/l: P<0.01) while 0280 group showed an intermediated level. NEFA as indicators of body lipids mobilization showed the highest in C group (0.50 mmol/l) and lower in 0280 group (0.29 mmol/l) (P<0.01) while 0450 showed an intermediated level. Opposite results were found for leptinwhich showed the highest level in 0280 group and the lowest in C group (4.08 ng/mL vs3.08 ng/mL: P<0.05) while 0450 group showed an intermediate level. No significant differences were found in the other parameters although cortisol and insulin are key players in the control of intermediary metabolism and glucose as indicator of energy balance. In conclusion leptin, T3, NEFA levels in 0450 group put in eveidence a better energy utilization for milk yield although the trend of these parameters showed in 0280 group should be explained by a probably different genetic valueof the cows among farms. Further analyses will be desiderable

No full textCumulative trauma and perceived community resilience: A serial mediation model
No full textCommunities affected by cumulative trauma can experience negative psychological reactions but also posttraumatic growth and community resilience, which promote adaptation and preparation for future traumatic events. This study aims to investigate the mechanisms that mediate the relationship between traumatic events and perceived community resilience. Participants were 118 Italian adults who experienced cumulative trauma and were recruited to complete an online survey. A serial multiple mediation model was estimated to assess whether the impact of the Morandi bridge collapse and posttraumatic growth mediated the relationship between the psychological impact of the Covid-19 pandemic and perceived community resilience. The impact of the collapsed bridge and posttraumatic growth in serial partially mediated the relationship between the impact of the Covid-19 pandemic and perceived community resilience. The impact of cumulative trauma can be considered through an ecological perspective that considers the consequences of these events in relation to community resilience
Analisi dei danni da frana in un’area campione del Sub-Appennino Dauno (Italia meridionale)
No full textIl presente lavoro riguarda l’analisi dei danni da frana nel comune di Celenza Valfortore, nel Sub-Appennino Dauno, in provincia di Foggia (Puglia). In un’area intensamente modellata da fenomeni gravitativi, molti dei quali in stato attivo o quiescente, è stata svolta un’analisi dei metodi ed approcci disponibili in letteratura, relativi agli effetti prodotti da fenomeni franosi su edifici e infrastrutture antropiche. Avendo individuato
il metodo proposto da Chiocchio, Iovine & Parise (1997) come il più appropriato agli obiettivi dello studio, si è proceduto al rilevamento dei danni da frana, ed alla redazione di carte del danno. Queste sono state confrontate con recenti carte inventario delle frane per lo stesso settore, derivanti da analisi multitemporale di fotografie aeree. Lo studio ha evidenziato come l’attenta analisi dei danni riscontrati su edifici e infrastrutture
possa essere un valido supporto alla tradizionale analisi fotointerpretativa in aree a forte urbanizzazione, all’interno delle quali le evidenze morfologiche risultano spesso mascherate dalla presenza di edifici
