Soil protist function varies with elevation in the Swiss Alps

Nicolas Jean Philippe Guex, Edward Mitchell, Enrique Lara, Aline Buri

Protists are abundant and play key trophic functions in soil. Documenting how their trophic contributions vary across large environmental gradients is essential to understand and predict how biogeochemical cycles will be impacted by global changes. Here, u ...

Virus-Mediated Cell-Cell Fusion

Cell-cell fusion between eukaryotic cells is a general process involved in many physiological and pathological conditions, including infections by bacteria, parasites, and viruses. As obligate intracellular pathogens, viruses use intracellular machineries ...

Structure of a PSI-LHCI-cyt b(6)f supercomplex in Chlamydomonas reinhardtii promoting cyclic electron flow under anaerobic conditions

Henning Paul-Julius Stahlberg

Photosynthetic linear electron flow (LEF) produces ATP and NADPH, while cyclic electron flow (CEF) exclusively drives photophosphorylation to supply extra ATP. The fine-tuning of linear and cyclic electron transport levels allows photosynthetic organisms t ...

Dispositif et procédé pour l'évaluation de la contraction cellulaire

Boris Hinz, Pierre Jean Arnould Wipff

A method for assessing cell contraction includes adhering contractile cells to an oxidized and cellular adhesion activated surface of a biocompatible silicone elastomer film. The biocompatible silicone elastomer film allows the cells to contract and wrinkl ...

Use of VacA as a Vaccine Antigen

Dominique Velin, Mati André Marie Moyat

One of the major toxins secreted by H. pylori is the Vacuolating cytotoxin A (VacA) named after its ability to induce the formation of "vacuole"-like membrane vesicles in the cytoplasm of gastric cells. VacA has been associated with the disruption of mitoc ...

Nano Secondary Ion Mass Spectrometry Imaging of Dopamine Distribution Across Nanometer Vesicles

Anders Meibom, Anna Larsson

We report an approach to spatially resolve the content across nanometer neuroendocrine vesicles in nerve-like cells by correlating super high-resolution mass spectrometry imaging, NanoSIMS, with transmission electron microscopy (TEM). Furthermore, intracel ...

An intracellular replication niche for Vibrio cholerae in the amoeba Acanthamoeba castellanii

Melanie Blokesch, Catherine Maclachlan, Tiziana Scrignari, Charles Ulric V Van der Henst

Vibrio cholerae is a human pathogen and the causative agent of cholera. The persistence of this bacterium in aquatic environments is a key epidemiological concern, as cholera is transmitted through contaminated water. Predatory protists, such as amoebae, a ...

Interactions of silver and polystyrene nanoparticles with algae

Xiaomei Li

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 ...

Bacterial Resource Management for Nutrient Removal in Aerobic Granular Sludge Wastewater Treatment Systems

David Gregory Weissbrodt

The approach of wastewater treatment has shifted towards a holistic view in order to achieve sustainability in addition to environmental protection. The aerobic granular sludge (AGS) technology, which relies on the use of fast-settling granular biofilms ca ...

Impaired myogenesis in estrogen-related receptor γ (ERRγ)-deficient skeletal myocytes due to oxidative stress

Johan Auwerx

Specialized contractile function and increased mitochondrial number and oxidative capacity are hallmark features of myocyte differentiation. The estrogen-related receptors (ERRs) can regulate mitochondrial biogenesis or mitochondrial enzyme expression in s ...
