3D feedback and observation for motor learning: Application to the roundoff movement in gymnastics

Le Naour, Thibaut ; Ré, Chiara ; Bresciani, Jean-Pierre

In: Human Movement Science, 2019, vol. 66, p. 564-577

In this paper, we assessed the efficacy of different types of visual information for improving the execution of the roundoff movement in gymnastics. Specifically, two types of 3D feedback were compared to a 3D visualization only displaying the movement of the expert (observation) as well as to a more ‘traditional’ video observation. The improvement in movement execution was measured using...

3D imaging of undissected optically cleared Anopheles stephensi mosquitoes and midguts infected with Plasmodium parasites

Niz, Mariana De ; Kehrer, Jessica ; Brancucci, Nicolas M. B. ; Moalli, Federica ; Reynaud, Emmanuel G. ; Stein, Jens V. ; Frischknecht, Friedrich

In: PLOS ONE, 2020, vol. 15, no. 9, p. e0238134

Malaria is a life-threatening disease, caused by Apicomplexan parasites of the Plasmodium genus. The Anopheles mosquito is necessary for the sexual replication of these parasites and for their transmission to vertebrate hosts, including humans. Imaging of the parasite within the insect vector has been attempted using multiple microscopy methods, most of which are hampered by the presence of...

3D model related to the publication: A new species of the large-headed coastal marine turtle Solnhofia (Testudinata, Thalassochelydia) from the Late Jurassic of NW Switzerland

Anquetin, Jérémy ; Püntener, Christian

In: MorphoMuseuM, 2020, vol. 6, no. 4, p. e118

This contribution contains the 3D surface model of the holotype cranium of the Late Jurassic thalassochelydian turtle Solnhofia brachyrhyncha described and figured in the publication of Anquetin and Püntener (2020).

3D models related to the publication: New material of Epiaceratherium and a new species of Mesaceratherium clear up the phylogeny of the early Rhinocerotidae (Perissodactyla)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: MorphoMuseuM, 2020, vol. 6, no. 3, p. e116

The present 3D Dataset contains two 3D models described in Tissier et al. (https://doi.org/10.1098/rsos.200633): the only known complete mandible of the early-branching rhinocerotoid Epiaceratherium magnum Uhlig, 1999, and a hypothetical reconstruction of the complete archetypic skull of Epiaceratherium Heissig, 1969, created by merging three cranial parts from three distinct Epiaceratherium...

3D morphology of pharyngeal dentition of the genus Capoeta (Cyprinidae): Implications for taxonomy and phylogeny

Ayvazyan, Anna ; Vasilyan, Davit ; Böhme, Madelaine

In: Journal of Zoological Systematics and Evolutionary Research, 2019, vol. 57, no. 1, p. 179–190

Capoeta is a herbivorous cyprinid fish genus, widely distributed in water bodies of Western Asia. Recent species show a distinct biogeographic pattern with endemic distribution in large fluvial drainage basins. As other cyprinids, the species of this genus are characterized by the presence of the pharyngeal bone with pharyngeal teeth. Despite this, the detailed morphology of the pharyngeal...

3-Mercaptopyruvate sulfurtransferase supports endothelial cell angiogenesis and bioenergetics

Abdollahi Govar, Armita ; Törő, Gábor ; Szaniszlo, Peter ; Pavlidou, Athanasia ; Bibli, Sofia‐Iris ; Thanki, Ketan ; Resto, Vicente A. ; Chao, Celia ; Hellmich, Mark R. ; Szabo, Csaba ; Papapetropoulos, Andreas ; Módis, Katalin

In: British Journal of Pharmacology, 2020, vol. 177, no. 4, p. 866–883

During angiogenesis, quiescent endothelial cells (ECs) are activated by various stimuli to form new blood vessels from pre‐existing ones in physiological and pathological conditions. Many research groups have shown that hydrogen sulfide (H2S), the newest member of the gasotransmitter family, acts as a proangiogenic factor. To date, very little is known about the regulatory role of...

400 years of debris flow activity and triggering weather conditions: Ritigraben VS, Switzerland

Stoffel, Markus ; Lièvre, Igor ; Conus, Delphine ; Grichting, Michael A. ; Raetzo, Hugo ; Gärtner, Holger W. ; Monbaron, Michel

In: Arctic Antarctic and Alpine Research, 2005, vol. 37(3), p. 387-395

Three major rainfall events have caused considerable damage in the Valais region (Swiss Alps) since 1987. While important debris flows originating from periglacial environments were recorded during the August 1987 and September 1993 rainfall events, no debris flows occurred in October 2000. This paper aims at putting these large area events and the apparent increase in debris flow frequency into...

4,4’Dimethoxychalcone: a natural flavonoid that promotes health through autophagy-dependent and -independent effects

Zimmermann, Andreas ; Kainz, Katharina ; Hofer, Sebastian J. ; Bauer, Maria A. ; Schroeder, Sabrina ; Dengjel, Jörn ; Pietrocola, Federico ; Kepp, Oliver ; Ruckenstuhl, Christoph ; Eisenberg, Tobias ; Sigrist, Stephan J. ; Madeo, Frank ; Carmona-Gutierrez, Didac ; Kroemer, Guido

In: Autophagy, 2019, vol. 15, no. 9, p. 1662–1664

The age-induced deterioration of the organism results in detrimental and ultimately lethal pathologies. The process of aging itself involves a plethora of different mechanisms that should be subverted concurrently to delay and/or prevent age- related maladies. We have identified a natural compound, 4,4ʹ-dimethoxychalcone (DMC), which promotes longevity in yeast, worms and flies, and protects...

The 4D Model of the country image : an integrative approach from the perspective of communication management

Buhmann, Alexander ; Ingenhoff, Diana

In: The International communication gazette, 2015, vol. 77, no. 1, p. 102-124

This conceptual article proposes a new integrative model of the country image by drawing on advances from the fields of business studies, social psychology, political science, and communication science. To interrelate different approaches, a communication management perspective is applied, providing a basic terminological framework systemizing the central constructs of country image, country...
