In vivo nuclear translocation of mineralocorticoid and glucocorticoid receptors in rat kidney: differential effect of corticosteroids along the distal tubule

Ackermann, Daniel ; Gresko, Nikolay ; Carrel, Monique ; Loffing-Cueni, Dominique ; Habermehl, Daniel ; Gomez-Sanchez, Celso ; Rossier, Bernard C. ; Loffing, Johannes

In: American Journal of Physiology - Renal Physiology, 2011, vol. 299, no. 6, p. F1473-F1485

Aldosterone and corticosterone bind to mineralocorticoid (MR) and glucocorticoid receptors (GR), which, upon ligand binding, are thought to translocate to the cell nucleus to act as transcription factors. Mineralocorticoid selectivity is achieved by the 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) that inactivates 11β-hydroxy glucocorticoids. High expression levels of 11β-HSD2...

Centrality of Religiosity Scale - Test of Model Configuration, Reliability, and Consistency in Romania, Georgia, and Russia

Ackert, Michael ; Schöbi, Dominik (Dir.)

Thèse de doctorat : Université de Fribourg, 2021.

Messung ist grundlegend für in der Wissenschaft. Die Sozialwissenschaften im Allgemeinen und die Psychologie im Besonderen sind auf objektive, valide und reliable psychometrische Skalen angewiesen. Die Religions- und Spiritualitätspsychologie war im 20. Jahrhundert lange Zeit auf der Suche nach einem ganzheitlichen und vertrauenswürdigen Instrumentarium zur Erfassung psychologischer...

Understanding amyloid aggregation by statistical analysis of atomic force microscopy images

Adamcik, Jozef ; Jung, Jin-Mi ; Flakowski, Jérôme ; Rios, Paolo De Los ; Dietler, Giovanni ; Mezzenga, Raffaele

In: Nature Nanotechnology, 2010, vol. 5, p. 423 - 428

The aggregation of proteins is central to many aspects of daily life, including food processing, blood coagulation, eye cataract formation disease and prion-related neurodegenerative infections. However, the physical mechanisms responsible for amyloidosis—the irreversible fibril formation of various proteins that is linked to disorders such as Alzheimer's, Creutzfeldt–Jakob and Huntington's...

A Koebe distortion theorem for quasiconformal mappings in the Heisenberg group

Adamowicz, Tomasz ; Fässler, Katrin ; Warhurst, Ben

In: Annali di Matematica Pura ed Applicata (1923 -), 2020, vol. 199, no. 1, p. 147–186

We prove a Koebe distortion theorem for the average derivative of a quasiconformal mapping between domains in the sub-Riemannian Heisenberg group H1. Several auxiliary properties of quasiconformal mappings between subdomains of H1 are proven, including BMO estimates for the logarithm of the Jacobian. Applications of the Koebe theorem include diameter bounds for images of curves, comparison of...

Robust changes and sources of uncertainty in the projected hydrological regimes of Swiss catchments

Addor, Nans ; Rössler, Ole ; Köplin, Nina ; Huss, Matthias ; Weingartner, Rolf ; Seibert, Jan

In: Water Resources Research, 2014, p. -

Projections of discharge are key for future water resources management. These projections are subject to uncertainties, which are difficult to handle in the decision process on adaptation strategies. Uncertainties arise from different sources such as the emission scenarios, the climate models and their post-processing, the hydrological models and natural variability. Here we present a detailed...

Convexity of complements of tropical varieties, and approximations of currents

Adiprasito, Karim ; Babaee, Farhad

In: Mathematische Annalen, 2019, vol. 373, no. 1, p. 237–251

The goal of this note is to affirm a local version of conjecture of Nisse–Sottile [19] on higher convexity of complements of tropical varieties, while providing a family of counter-examples for the global Nisse–Sottle conjecture in any codimension and dimension higher than one. Moreover, it is shown that, surprisingly, this family also provides a family of counter-examples for the...

Portfolio diversification in Europe

Adjaouté, Kpate ; Danthine, Jean-Pierre ; Isakov, Dušan

(FAME Research Paper ; 86)

Have the euro and accompanying measures of financial integration had a discernable impact on the degree of diversification of European investors? This is an empirical question that this paper tries to answer by exploring four alternative avenues. First we focus on the final outcome: If European investors are indeed better diversified, their consumption should be increasingly correlated. Second we...
