The Binding of Aβ42 Peptide Monomers to Sphingomyelin/Cholesterol/Ganglioside Bilayers Assayed by Density Gradient Ultracentrifugation
(MDPI, 2020-02-29)
The binding of Aβ42 peptide monomers to sphingomyelin/cholesterol (1:1 mol ratio) bilayers containing 5 mol% gangliosides (either GM1, or GT1b, or a mixture of brain gangliosides) has been assayed by density gradient ...
Exploring Polar Headgroup Interactions Between Sphingomyelin and Ceramide with Infrared Spectroscopy
(Nature, 2020-10-19)
Ceramide is a major actor in the sphingolipid signaling pathway elicited by various kinds of cell stress. Under those conditions ceramide (Cer) is produced in the plasma membrane as a product of sphingomyelin (SM) hydrolysis, ...
Versión reducida del cuestionario CaMir (CaMir-R) para la evaluación del apego
(Colegio Oficial de Psicólogos del Principado de Asturias, 2011)
The CaMir is a questionnaire aimed at measuring attachment cognitions. It is based on subjects' evaluations of past and present attachment experiences and family functioning. It is a widely used tool both in research and ...
Upper Palaeolithic hunter–gatherer societies in the Basque Country (Iberian Peninsula) in the light of palaeoenvironmental dynamics in the last Glacial Period: cultural adaptations and the use of biotic resources
(Cambridge University Press, 2023-07)
Upper Palaeolithic archaeological sites in the Basque Country have been excavated for over a century. They have yielded a rich palaeoenvironmental record with zoological and botanical remains that have been obtained in ...
Neanderthal teeth from Lezetxiki (Arrasate, Iberian Peninsula): New insights and reassessment
(Wiley, 2023-04)
Objectives
We reassess the taxonomic assignment and stratigraphic context of a permanent upper first molar and a permanent lower third premolar recovered from the archeological site of Lezetxiki in the North of the ...
The return to the Iberian Peninsula: first Quaternary record of Muscardinus and a palaeogeographical overview of the genus in Europe
(Elsevier, 2015-05-18)
Although the earliest record of the genus Muscardinus dates from the Middle Miocene in Spain, no mention has been reported since the Lower Pliocene in the Iberian Peninsula. In this paper, Quaternary fossil remains of a ...
Dancing with wolves at Schöningen 13II-4
(Propylaem, 2021-06-12)
The Schöningen 13II-4 site has produced a wealth of insight into the hunting and butchery activities of Middle
Pleistocene hominins, highlighted by the famous Schöningen spears preserved with hundreds of cut-marked and ...
Bending rigidity, sound propagation and ripples in flat graphene
(Springer Nature, 2024-05-16)
Many of the applications of graphene rely on its uneven stiffness and high thermal conductivity, but the mechanical properties of graphene—and, in general, of all two-dimensional materials—are still not fully understood. ...
Biogeographic Analysis of Upper Pleistocene Felid (Felis, Lynx and Panthera) Remains in Archaeological Sites on the Iberian Peninsula
(Propylaeum, 2022-04-26)
This paper aims to introduce the biogeographic distribution of felids (Felis, Lynx and Panthera). The analysed period is within the last glacial phases. This period was quite unstable, changing climatic conditions affected ...
Cohomology of p-groups of nilpotency class smaller than p
(De Gruyter, 2018-01-17)
Let p be a prime number, let d be an integer and let G be a d-generated finite p-group of nilpotency class smaller than p. Then the number of possible isomorphism types for the mod p cohomology algebra H^∗(G;F_p) is bounded ...
