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, ...
Alimentación y patrones de movilidad territorial en las últimas sociedades cazadoras-recolectoras y las primeras productoras en el Pirineo Occidental.
(2019-03-07)
En esta Tesis Doctoral se estudian, mediante análisis de isótopos de carbono, nitrógeno y estroncio, los patrones de alimentación y movilidad territorial de los grupos humanos de la Prehistoria Reciente. Para ello, se han ...
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 ...
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 ...
Genetic turnovers and northern survival during the last glacial maximum in European brown bears
(John Wiley & Sons, 2019-05-29)
The current phylogeographic pattern of European brown bears (Ursus arctos) has
commonly been explained by postglacial recolonization out of geographically distinct
refugia in southern Europe, a pattern well in accordance ...

(Propylaeum, 2018-05-11)
This volume is a collection of papers from the conference titled “Retouching the Palaeolithic: Becoming Human and the Origins of Bone Tool Technology” held in October 2015 at Schloss Herrenhausen in Hannover, Germany. With ...
Human behavioural adaptations to interglacial lakeshore environments. An introduction
(Propylaeum, University of Heidelberg, 2020-04-24)
During the course of human evolution, we have suc-
cessfully adapted to various environments. Chang-
ing climates and landscapes often required new
behavioural strategies for survival; human societies
indeed came into ...
A zooarchaeological and taphonomic perspective of hominin behaviour from Schöningen 13II-4 "Spear Horizon",
(Propylaeum, University of Heidelberg, 2020-04-24)
The Schöningen 13II-4 “Spear Horizon” is among the most famous lakeshore archaeological sites dating from the Middle Pleistocene in Europe. Multiple well-crafted wooden spears recovered together with a large assemblage of ...
Isothermal oxidation kinetics of nitrided Ti-6Al-4V studied by infrared emissivity
(Elsevier, 2020-08-15)
The oxidation kinetics of Ti-6Al-4V samples nitrided in forming gas (N2+5%H2) between 520 and 805 °C is investigated using infrared emissivity measurements. Several kinetic exponents have been observed depending on temperature ...
