Tailored electrospun nanofibrous polycaprolactone/gelatin scaffolds into an acid hydrolytic solvent system
2018
[EN] Blended nanofibrous scaffolds based on polycaprolactone (PCL) and gelatin (Ge) were successfully prepared. A formic/acetic acid (1:1) mixture was used to dissolve PCL/Ge blends from 100/0 to 20/80 %wt in steps of 10 %wt. The hydrolysis of the PCL diluted in the formic/acetic acid mixture was considered as a method for tailoring the surface morphology and physicochemical features of the nanofibrous PCL/Ge scaffolds as a function of the dissolution time. The fibre diameter remained in the nanoscale range for all the studied scaffolds, which is crucial to mimic the extra-cellular matrix size. The reduction of the intrinsic viscosity, molar mass and hydrodynamic radius found for the PCL mo…
Action simulation in the human brain: Twelve questions
2013
Although the idea of action simulation is nowadays popular in cognitive science, neuroscience and robotics, many aspects of the simulative processes remain unclear from empirical, computational, and neural perspectives. In the first part of the article, we provide a critical review and assessment of action simulation theories advanced so far in the wider literature of embodied and motor cognition. We focus our analysis on twelve key questions, and discuss them in the context of human and (occasionally) primate studies. In the second part of the article, we describe an integrative neuro-computational account of action simulation, which links the neural substrate (as revealed in neuroimaging …
Il Fast Track nelle fratture di femore può davvero favorire risultati clinici migliori?
2016
Le attuali linee guida raccomandano di effettuare il trattamento chirurgico di stabilizzazione o sosti- tuzione protesica entro 24-48 ore dall’accesso ospedaliero, al ne di migliorare il risultato funziona- le, ridurre il rischio di mortalità, la degenza ospedaliera e le complicazioni post-operatorie. Tuttavia, la mancanza di studi randomizzati rappresenta un importantissimo limite scienti co dal momento che ad oggi la migliore evidenza scienti ca sul timing chirurgico nelle fratture di collo femore si basa esclusivamente su studi prospettici e retrospettivi. In questo articolo, viene descritto il percorso ospedaliero per il trattamento delle fratture del collo del femore nel paziente anzia…
A specific picture of speech disturbances in Polish speaking patients with mixed dysarthria in multiple sclerosis (MS) and in Wilson's disease (WD)
2014
The aim of this paper is to compare a specific picture of speech disturbances in Polish-speaking patients with mixed dysarthria in multiple sclerosis (MS), and in Wilson’s disease (WD). We selected for the experiment 20 persons with dysarthria of different origin: 10 persons with dysarthria in multiple sclerosis (MS), and 10 persons with dysarthria in Wilson’s disease (WD). The compared groups were similar in age and the severity of the dysarthria. Patients read 11 words containing selected Polish sounds distinguished according to the manner of articulation. The results were qualitatively and quantitatively analyzed (using a non-parametric Mann-Whitney U test). The picture of speech product…
Cortical networks show characteristic recruitment patterns after somatosensory stimulation by pneumatically evoked repetitive hand movements in newbo…
2022
Abstract Controlled assessment of functional cortical networks is an unmet need in the clinical research of noncooperative subjects, such as infants. We developed an automated, pneumatic stimulation method to actuate naturalistic movements of an infant’s hand, as well as an analysis pipeline for assessing the elicited electroencephalography (EEG) responses and related cortical networks. Twenty newborn infants with perinatal asphyxia were recruited, including 7 with mild-to-moderate hypoxic–ischemic encephalopathy (HIE). Statistically significant corticokinematic coherence (CKC) was observed between repetitive hand movements and EEG in all infants, peaking near the contralateral sensorimotor…
Effects of Functional Strength Training on Functional Movement and Balance in Middle-Aged Adults
2021
Functional movement deficiencies cause falls and injuries in adults. Functional strength training (FST) is emerging as a new training method for athletes, middle-aged and older adults, to improve functional movement: The present study was conducted in order to investigate the effects of FST on balance and functional movement in healthy and independent middle-aged adults. The sample for this study consisted of 46 physically active individuals (24 female and 22 male). A total of 46 subjects were divided based on randomly into the functional strength training (FST) group (n = 26) aged: 51.55 ± 3.73 years; height: 168.69 ± 8.8 cm; body mass: 75.88 ± 12.18; and traditional s…

A scalable school‐based intervention to increase early adolescents' motor competence and health‐related fitness
2023
Schools are key settings for the promotion of students' physical activity, fitness, and motor competence. The purpose of our study was to investigate the efficacy of a 5-month-long intervention program that aimed to increase students' motor competence and health-related fitness during school days. We conducted a quasi-experimental study with 325 Finnish Grade 5 (Mage = 11.26, SD = 0.33) students from five schools. Two schools were allocated to the intervention group and three schools to the control group. The intervention consisted of three components: (a) weekly 20 min session during regular PE lessons, (b) weekly 20 min session during recess, and (c) daily 5-minute-long classroom activity…
Identifying childhood movement profiles and tracking physical activity and sedentary time across 1 year
2020
This study identified movement profiles in childhood and tracked longitudinal changes in moderate‐to‐vigorous physical activity and sedentary time across identified profiles. A sample consisted of 491 Finnish 5th Grade children (girls 275, boys 216; Mage = 11.27 ± .32). A latent profile analysis strategy was used to identify homogenous movement profiles that included measures of motor competence, perceived competence, and cardiorespiratory and muscular fitness. To examine a one‐year changes in moderate‐to‐vigorous physical activity and sedentary time among movement profiles, a mixed between‐within subjects analysis of variance with Tukey's post hoc ‐tests was conducted. Results revealed thr…
Kestävyyskunnon ja kehonkoostumuksen vaikutus työmuistiin ja motoriseen nopeuteen
2014
Johanna Kautto (2014). Kestävyyskunnon ja kehonkoostumuksen vaikutus työmuistiin ja motoriseen nopeuteen. Terveystieteiden laitos, Jyväskylän yliopisto, liikuntalääketieteen pro gradu –tutkielma, 47 s., 6 liitettä. Kognitiiviset toiminnot muuttuvat ikääntyessä neuroanatomisista ja -fysiologisista muutoksista johtuen. Kognitiivisten toimintojen säilymiseen vaikuttavat terveydentila ja fyysinen aktiivisuus. Tutkimuksissa on ollut viitteitä siitä, että myös kehonkoostumuksella olisi vaikutusta kognitiivisiin toimintoihin. Tässä työssä selvitettiin kestävyyskunnon ja kehonkoostumuksen vaikutusta työmuistia ja motorista nopeutta arvioivista neuropsykologisista testeistä suoriutumiseen ikääntynei…
