Controlling the Collective Transport of Large Passive Particles With Suspensions of Microorganisms

Small, EarlyView.
Directional light stimuli induce the accumulation of microalgae in suspensions of Chlamydomonas reinhardtii. This accumulation triggers large scale bioconvection rolls capable of macroscale transport. Exploiting these bioconvective flows enables to collectively transport of hundreds of large passive particles, paving the way for future applications in ...

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

A Microfluidic Design for Quantitative Measurements of Shear Stress-Dependent Adhesion and Motion of Dictyostelium discoideum Cells

Biomimetics
Shear stress plays a crucial role in modulating cell adhesion and signaling. We present a microfluidic shear stress generator used to investigate the adhesion dynamics of Dictyostelium discoideum, an amoeba cell model organism with well-characterized ...

Relationship Between Fecal Bile Acid Profile and Intestinal Microbiota in Patients With Chronic Radiation Enteritis

Journal of Digestive Diseases, EarlyView.
Patients with chronic radiation enteritis (CRE) demonstrate dysregulated bile acid (BA) metabolism, characterized by an increased proportion of primary BAs and a decreased proportion of secondary BAs. Moreover, the diversity of the intestinal microbiota is significantly reduced in individuals with CRE, and there is a bidirectional interaction between ...

Towards a Holarctic synthesis of peatland testate amoeba ecology: Development of a new continental-scale palaeohydrological transfer function for North America and comparison to European data

Quaternary Science Reviews, 2018
Fossil testate amoeba assemblages have been used to reconstruct peatland palaeohydrology for more than two decades. While transfer function training sets are typically of local-to regional-scale in extent, combining those data to cover broad ...

Untangling nutrient co‐regulation of ombrotrophic peatland development

Boreas, EarlyView.
Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...
