Behavioural and biochemical stress responses of Palinurus elephas after exposure to boat noise pollution in tank
2014
This study examined the effects of boat noise on the behavioural and biochemical parameters of the Mediterranean spiny lobster (Palinurus elephas).The experiment was conducted in a tank equipped with a video and audio recording system. 18 experimental trials, assigned to boat noise and control conditions, were performed using lobsters in single and group of 4 specimens. After a 1. h habituation period, we audio- and video-recorded the lobsters for 1. h. During the experimental phase, the animals assigned to the boat groups were exposed to boat noise pollution (a random sequence of boat noises). Exposure to the noise produced significant variations in locomotor behaviours and haemolymphatic …
Movements Execution in Amnestic Mild Cognitive Impairment and Alzheimer’s Disease
2007
We evaluated the relationship between motor and neuropsychological deficits in subjects affected by amnestic Mild Cognitive Impairment (aMCI) and early Alzheimer’s Disease (AD). Kinematics of goal-directed movement of aMCI and AD subjects were compared to those of age-matched control subjects. AD showed a slowing down of motor performance compared to aMCI and controls. No relationships were found between motor and cognitive performances in both AD and aMCI. Our results suggest that the different motor behaviour between AD and aMCI cannot be related to memory deficits, probably reflecting the initial degeneration of parietal-frontal circuits for movement planning. The onset of motor dysfunct…
Objectively assessed vigorous physical activity and motor coordination are associated in 11‐year old children
2019
This cross‐sectional study examined the associations between gender, sports club (SC) participation, physical activity (PA), motor coordination (MQ) and object control skill (TC). 11 year‐old children (n = 477) wore accelerometers during seven consecutive days for the analysis of moderate PA (MPA) and vigorous PA (VPA). To detect motor competence (MC), children's motor coordination was measured using the KTK (MQ), and object control skill with throw‐and‐catch task (TC). Sports club (SC) status was obtained by a questionnaire. Boys had higher levels of MPA (F = 50.45, P<0.001) and VPA (F = 11.13, P = 0.001), and were better in TC (F = 39.83, P < 0.001) than girls. SC participants outperforme…
HPMA Based Amphiphilic Copolymers Mediate Central Nervous Effects of Domperidone
2011
In this study we give evidence that domperidone encapsulated into amphiphilic p(HPMA)-co-p(laurylmethacrylate) (LMA) copolymer aggregates is able to cross the blood-brain barrier, since it affected motor behaviour in animals, which is a sensitive measure for CNS actions. Carefully designed copolymers based on the clinically approved p(HPMA) were selected and synthesized by a combination of controlled radical polymerization and post-polymerization modification. The hydrodynamic radii (R(h) ) of amphiphilic p(HPMA)-co-p(LMA) alone and loaded with domperidone were determined by fluorescence correlation spectroscopy.
Eye Kinematics of Athletes in Non-Familiar Sports Situations
2008
Biological motion can hardly be imitated, starting from how a person observes and learns motor behaviour. We recorded eye movements of 13 female ball games athletes and 13 age-matched controls observing videos of unfamiliar sports. The athletes are better at alternating between faster and slower eye movement modalities. They initially use longer but fewer fixations than the non-athletes.
