Notes on the cheek region of the Late Jurassic theropod dinosaur Allosaurus

Evers, Serjoscha W. ; Foth, Christian ; Rauhut, Oliver W.M.

In: PeerJ, 2020, vol. 8, p. e8493

Allosaurus, from the Late Jurassic of North America and Europe, is a model taxon for Jurassic basal tetanuran theropod dinosaurs. It has achieved an almost iconic status due to its early discovery in the late, 19th century, and due to the abundance of material from the Morrison Formation of the western U.S.A., making Allosaurus one of the best-known theropod taxa. Despite this, various...

Biological sex influences antibody responses to routine vaccinations in the first year of life

Zimmermann, Petra ; Perrett, Kirsten P. ; Ritz,  Nicole ; Flanagan, Katie L. ; Robins-Browne, Roy ; Klis, Fiona R. M. van der ; Curtis, Nigel ; the MIS BAIR group

In: Acta Paediatrica, 2019, p. -

Aim We investigated the effect of early-life factors, namely sex, delivery mode, feeding method and antibiotic exposure, on antibody responses to routine vaccinations administered during the first year of life. Methods One and seven months after the primary course of routine vaccines and 1 month after routine vaccines at 12 months of age, antibodies against 26 vaccine antigens were measured...

Multilevel regulation of the glass locus during Drosophila eye development

Fritsch, Cornelia ; Bernardo-Garcia, F. Javier ; Humberg, Tim-Henning ; Mishra, Abhishek Kumar ; Miellet, Sara ; Almeida, Silvia ; Frochaux, Michael V. ; Deplancke, Bart ; Huber, Armin ; Sprecher, Simon G.

In: PLOS Genetics, 2019, vol. 15, no. 7, p. e1008269

Development of eye tissue is initiated by a conserved set of transcription factors termed retinal determination network (RDN). In the fruit fly Drosophila melanogaster, the zinc-finger transcription factor Glass acts directly downstream of the RDN to control identity of photoreceptor as well as non-photoreceptor cells. Tight control of spatial and temporal gene expression is a critical...

Aging effects on prefrontal cortex oxygenation in a posture-cognition dual-task: an fNIRS pilot study

Marusic, Uros ; Taube, Wolfgang ; Morrison, Shawnda A. ; Biasutti, Lea ; Grassi, Bruno ; Pauw, Kevin De ; Meeusen, Romain ; Pisot, Rado ; Ruffieux, Jan

In: European Review of Aging and Physical Activity, 2019, vol. 16, no. 1, p. 2

The aging process alters upright posture and locomotion control from an automatically processed to a more cortically controlled one. The present study investigated a postural-cognitive dual-task paradigm in young and older adults using functional Near- Infrared Spectroscopy (fNIRS).Methods: Twenty healthy participants (10 older adults 72 ± 3 y, 10 young adults 23 ± 3 y) performed a...

Absence of calretinin protein expression in malignant mesotheliomas from asbestos-exposed NF2+/− mice and mouse mesothelioma cell lines from various mouse strains

Blum, Walter ; Henzi, Thomas ; Châtel-Soulet, Hugues-Etienne ; Pecze, Laszlo ; Wörthmüller Rodriguez, Janine ; Vrugt, Bart ; Schwaller, Beat

In: Biomarker Research, 2018, vol. 6, no. 1, p. 19

Calretinin is the most widespread positive marker for the immunohistochemical identification of malignant mesothelioma (MM) and was proposed to serve as a blood- based biomarker. Functionally, evidence has accumulated that calretinin might be implicated in MM tumorigenesis. We aimed to identify calretinin (CR; Calb2) in murine MM and reactive mesothelial cells in granuloma from...

A Ga-doped SnO2 mesoporous contact for UV stable highly efficient perovskite solar cells

Roose, Bart ; Johansen, Christian M. ; Dupraz, Kevin ; Jaouen, Thomas ; Aebi, Philipp ; Steiner, Ullrich ; Abate, Antonio

In: Journal of Materials Chemistry A, 2018, vol. 6, no. 4, p. 1850–1857

Increasing the stability of perovskite solar cells is a major challenge for commercialization. The highest efficiencies so far have been achieved in perovskite solar cells employing mesoporous TiO2 (m-TiO2). One of the major causes of performance loss in these m-TiO2-based perovskite solar cells is induced by UV- radiation. This UV instability can be solved by replacing TiO2 with SnO2; thus ...

New insights into the lifestyle of Allosaurus (Dinosauria: Theropoda) based on another specimen with multiple pathologies

Foth​, Christian ; Evers, Serjoscha W. ; Pabst, Ben ; Mateus, Octávio ; Flisch, Alexander ; Patthey, Mike ; Rauhut, Oliver W.M.

In: PeerJ, 2015, vol. 3, p. e940

Adult large-bodied theropods are often found with numerous pathologies. A large, almost complete, probably adult Allosaurus specimen from the Howe Stephens Quarry, Morrison Formation (Late Kimmeridgian–Early Tithonian), Wyoming, exhibits multiple pathologies. Pathologic bones include the left dentary, two cervical vertebrae, one cervical and several dorsal ribs, the left scapula, the left...

Flux Synthesis, Structure, Properties, and Theoretical Magnetic Study of Uranium(IV)-Containing A₂USi₆O₁₅ (A = K, Rb) with an Intriguing Green-to-Purple, Crystal-to-Crystal Structural Transition in the K Analogue

Morrison, Gregory ; Ramanantoanina, Harry ; Urland, Werner ; Smith, Mark D. ; Loye, Hans-Conrad zur

In: Inorganic Chemistry, 2015, vol. 54, no. 11, p. 5504–5511

Single crystals of uranium(IV)-containing A₂USi₆O₁₅ (A = K, Rb) were grown using the flux growth method. The two compounds crystallize in a new structure type related to Cs₂USi₆O₁₅. K₂USi₆O₁₅ exhibits an interesting crystal-to-crystal transition, which is accompanied by an intense color change. Magnetic properties are reported for A₂USi₆O₁₅ and differ from other...
