Motor cortical plasticity induced by motor learning through mental practice

2015

Several investigations suggest that actual and mental actions trigger similar neural substrates. Motor learning via physical practice results in long-term potentiation (LTP)-like plasticity processes, namely potentiation of M1 and a temporary occlusion of additional LTP-like plasticity. However, whether this neuroplasticity process contributes to improve motor performance through mental practice remains to be determined. Here, we tested skill learning-dependent changes in primary motor cortex (M1) excitability and plasticity by means of transcranial magnetic stimulation in subjects trained to physically execute or mentally perform a sequence of finger opposition movements. Before and after …

Transarterial chemoembolization versus sorafenib in patients with hepatocellular carcinoma and extrahepatic disease

2017

BackgroundSorafenib is the recommended treatment for advanced hepatocellular carcinoma (HCC), but transarterial chemoembolization (TACE) is performed in individual cases with limited extrahepatic spread. The aim of this study was to compare the outcome of patients with HCC and extrahepatic disease (EHD) treated with sorafenib and TACE.MethodsA total of 172 patients with HCC and EHD treated with sorafenib (n = 98) or TACE (n = 74) at three German referral centers (Hannover, Mainz and Hamburg) were included in this study. In order to reduce selection bias, patients were matched for significant demographic differences using a propensity score analysis.ResultsPatients with liver cirrhosis, high…

Methods of the investigation of bee pollen and bee bread

2017

The main purpose of this publication was to evaluate which types of studies are used with the purpose of the estimation of nutritional value of bee pollen and bee bread. Bee pollen and bee bread are important bee-products that contains large amounts of nutritional and essential active biological compounds. Among different bioactive compounds with antioxidant properties which could be found in bee pollen and bread are polyphenolic substances, flavonoids, unsaturated acids and carotenoids. Bee pollen and bee bread are investigated by plenty of scientists for different quality indexes over two last decades. However, the composition of bee pollen and bee bread are not yet standardized nor defin…

Administration of care to older patients in transition from hospital to home care services: home nursing leaders' experiences.

2013

Background Older persons in transition between hospital and home care services are in a particularly vulnerable situation and risk unfortunate consequences caused by organizational inefficiency. The purpose of the study reported here was to elucidate how home nursing leaders experience the administration of care to older people in transition from hospital to their own homes. Methods A qualitative study design was used. Ten home nursing leaders in two municipalities in southern Norway participated in individual interviews. The interview texts were audio taped, transcribed verbatim and analyzed by use of a phenomenological-hermeneutic approach. Results Three main themes and seven subthemes we…

The embodied self, the pattern theory of self, and the predictive mind

2018

Do we have to presuppose a self to account for human self-consciousness? If so, how should we characterize the self? These questions are discussed in the context of two alternatives, i.e., the no-self position held by \(\textit {Metzinger (2003, 2009)}\) and the claim that the only self we have to presuppose is a narrative self \(\textit {(Dennett, 1992; Schechtman, 2007; Hardcastle, 2008)}\) which is primarily an abstract entity. In contrast to these theories, I argue that we have to presuppose an embodied self, although this is not a metaphysical substance, nor an entity for which stable necessary and jointly sufficient conditions can be given. Self-consciousness results from an integrati…

Association between malocclusion and articulation of phonemes in early childhood

2021

ABSTRACT Objectives To evaluate the relationship between dental malocclusion and speech to understand the etiology of speech sound disorders (SSD) in schoolchildren and to make a correct diagnosis and treatment plan. Materials and Methods Articulation and dental occlusion, oromyofunctional evaluation with orofacial praxis and musculature, resting tongue position, and swallowing pattern were analyzed in 290 schoolchildren between the ages of 4 and 7 years. Statistical tests were considered significant for P < .05. Results A significant association between dental malocclusions (Angle Class II and III, anterior open bite, edge-to-edge bite, overjet and anterior crossbite) and phonetic a…

''Forward to the past''

2012

Carlini, Alessandro | Actis-Grosso, Rossana | Stucchi, Natale | Pozzo, Thierry; International audience; ''Our daily experience shows that the CNS is a highly efficient machine to predict the effect of actions into the future; are we so efficient also in reconstructing the past of an action? Previous studies demonstrated we are more effective in extrapolating the final position of a stimulus moving according to biological kinematic laws. Here we address the complementary question: are we more effective in extrapolating the starting position (SP) of a motion following a biological velocity profile? We presented a dot moving upward and corresponding to vertical arm movements that were masked i…

Influence of different types of astigmatism on visual acuity

2016

[EN] Purpose To investigate the change in visual acuity (VA) produced by different types of astigmatism (on the basis of the refractive power and position of the principal meridians) on normal accommodating eyes. Methods The lens induced method was employed to simulate a set of 28 astigmatic blur conditions on different healthy emmetropic eyes. Additionally, 24 values of spherical defocus were also simulated on the same eyes for comparison. VA was measured in each case and the results, expressed in logMAR units, were represented against of the modulus of the dioptric power vector (blur strength). Results LogMAR VA varies in a linear fashion with increasing astigmatic blur, being the slope o…
