Novel features of centriole polarity and cartwheel stacking revealed by cryo-tomography
Davide Demurtas, Georgios Hatzopoulos, Sergey Nazarov, Alexandra Bezler, Paul Guichard, Veronika Nemcíková Villímová
Centrioles are polarized microtubule-based organelles that seed the formation of cilia, and which assemble from a cartwheel containing stacked ring oligomers ofSAS-6 proteins. A cryo-tomography map of centrioles from the termite flagellateTrichonymphaspp. ...
2020Demographic stochasticity and resource autocorrelation control biological invasions in heterogeneous landscapes
Andrea Rinaldo, Andrea Giometto, Florian Altermatt
Mounting theoretical evidence suggests that demographic stochasticity, environmental heterogeneity and biased movement of organisms individually affect the dynamics of biological invasions and range expansions. Studies of species spread in heterogeneous la ...
Wiley2017Interaction of silver nanoparticles with algae and fish cells: a side by side comparison
Kristin Schirmer, Laura Sigg, Renata Behra, Yang Yue, Xiaomei Li
Background: Silver nanoparticles (AgNP) are widely applied and can, upon use, be released into the aquatic environment. This raises concerns about potential impacts of AgNP on aquatic organisms. We here present a side by side comparison of the interaction ...
Biomed Central Ltd2017Silver nanoparticle toxicity and association with the alga Euglena gracilis
Kristin Schirmer, Laura Sigg, Renata Behra, Xiaomei Li, Laetitia Bernard
The impact of silver nanoparticles (AgNPs) on aquatic algae has largely been studied with model species that possess a rigid cell wall. Here, we explored the interactions of AgNPs with Euglena gracilis, a green alga having no cell wall but a pellicle. The ...
Royal Soc Chemistry2015Generalized receptor law governs phototaxis in the phytoplankton Euglena gracilis
Andrea Rinaldo, Andrea Giometto, Amos Maritan, Florian Altermatt
Phototaxis, the process through which motile organisms direct their swimming toward or away from light, is implicated in key ecological phenomena (including algal blooms and diel vertical migration) that shape the distribution, diversity, and productivity ...
Natl Acad Sciences2015The role of fluctuations in ecological patterns and processes
Fluctuations are ubiquitous in nature and are relevant for nearly every ecological process. The main sources of fluctuations in population abundances are demographic and environmental stochasticity, whose effect on local population dynamics, metapopulation ...
EPFL2015Interactions of silver and polystyrene nanoparticles with algae
Nanoparticles have various physicochemical properties attributed by their small dimensions. The global production of nanoparticles lead to a raised concern for their environmental impacts. Algae are of highly ecological importance functioning as primary pr ...
EPFL2015Peptone Supplementation of Culture Medium Has Variable Effects on the Productivity of CHO Cells
Florian Maria Wurm, Lucia Baldi Unser, Yashas Rajendra, Fatemeh Davami
The optimization of cell culture conditions for growth and productivity of recombinant Chinese hamster ovary (CHO) cells is a critical step in biopharmaceutical manufacturing. In the present study, the effects of the timing and amount of peptone feeding of ...
