Engineering extracellular electron transfer for enhanced energy harvesting in microbial electrochemical devices

Mohammed Mouhib

Microorganisms known as exoelectrogens evolved the ability of transporting electrons across insulating biological membranes. In a physiological context, this enables respiration on extracellular electron acceptors and electron transfer to other organisms. ...

Preferential retention of algal carbon in benthic invertebrates: Stable isotope and fatty acid evidence from an outdoor flume experiment

Tom Ian Battin

According to the River Continuum Concept, headwater streams are richer in allochthonous (e.g. terrestrial leaves) than autochthonous (e.g. algae) sources of organic matter for consumers. However, compared to algae, leaf litter is of lower food quality, par ...

Outer membrane lipoprotein NlpI scaffolds peptidoglycan hydrolases within multi-enzyme complexes in Escherichia coli

Ann-Kristin Hov

The peptidoglycan (PG) sacculus provides bacteria with the mechanical strength to maintain cell shape and resist osmotic stress. Enlargement of the mesh-like sacculus requires the combined activity of peptidoglycan synthases and hydrolases. In Escherichia ...

Molecular profiling and functional analysis of macrophage-derived tumour extracellular vesicles

Tim Beltraminelli

Extracellular vesicles (EVs) are nanosized vesicles released by virtually all cell types. Increasing data suggest that EVs function in the regulation of intercellular communication both in physiological and pathological states. In cancer biology, mounting ...

House dust mite drives proinflammatory eicosanoid reprogramming and macrophage effector functions

Nicola Harris, Tiffany Babette Angélique Bouchery, Julia Esser-von Bieren

Background Eicosanoid lipid mediators play key roles in type 2 immune responses, for example in allergy and asthma. Macrophages represent major producers of eicosanoids and they are key effector cells of type 2 immunity. We aimed to comprehensively track e ...

Surviving anoxia in marine sediments: The metabolic response of ubiquitous benthic foraminifera (Ammonia tepida)

Anders Meibom, Stéphane Laurent Escrig, Emmanuelle Geslin, Charlotte Madeleine Nicole Lekieffre

High input of organic carbon and/or slowly renewing bottom waters frequently create periods with low dissolved oxygen concentrations on continental shelves and in coastal areas; such events can have strong impacts on benthic ecosystems. Among the meiofauna ...

Dysregulation of soluble epoxide hydrolase and lipidomic profiles in anorexia nervosa

Pierre Magistretti, Jiangyan Yang

Individuals with anorexia nervosa (AN) restrict eating and become emaciated. They tend to have an aversion to foods rich in fat. Because epoxide hydrolase 2 (EPHX2) was identified as a novel AN susceptibility gene, and because its protein product, soluble ...

Nutritional Omega-3 Deficiency Alters Glucocorticoid Receptor-Signaling Pathway and Neuronal Morphology in Regionally Distinct Brain Structures Associated with Emotional Deficits

Thomas Didier Larrieu

Extensive evidence suggests that long term dietary n-3 polyunsaturated fatty acids (PUFAs) deficiency results in altered emotional behaviour. We have recently demonstrated that n-3 PUFAs deficiency induces emotional alterations through abnormal corticoster ...

LRH-1 mediates anti-inflammatory and antifungal phenotype of IL-13-activated macrophages through the PPAR gamma ligand synthesis

Kristina Schoonjans

Liver receptor homologue-1 (LRH-1) is a nuclear receptor involved in the repression of inflammatory processes in the hepatointestinal tract. Here we report that LRH-1 is expressed in macrophages and induced by the Th2 cytokine IL-13 via a mechanism involvi ...

Characterization of hepatic fatty acids in mice with reduced liver fat by ultra-short echo time (1) H-MRS at 14.1 T in vivo

Rolf Gruetter, Ana Francisca Leal Silva Soares, Hongxia Lei

Alterations in the hepatic lipid content (HLC) and fatty acid composition are associated with disruptions in whole body metabolism, both in humans and in rodent models, and can be non-invasively assessed by (1) H-MRS in vivo. We used (1) H-MRS to character ...

Influence of diatoms on copepod reproduction. II. Uncorrelated effects of diatom-derived alpha,beta,gamma,delta-unsaturated aldehydes and polyunsaturated fatty acids on Calanus helgolandicus in the field

We set up a survey involving comprehensive chemical analyses of phytoplankton and the simultaneous monitoring of the reproductive response of Calanus helgolandicus. Hatching success and larvae development of C helgolandicus were monitored weekly with femal ...

Phospholipases and Galactolipases Trigger Oxylipin-Mediated Wound-Activated Defence in the Red Alga Gracilaria chilensis against Epiphytes

Johel Beltran Ramirez

We investigated the wound response of the commercially important red alga, Gracilaria chilensis, in order to obtain insight into its interaction with epiphytic pests. After wounding, the host releases free fatty acids as well as the hydroxylated eicosanoid ...

Formation of halogenated medium chain hydrocarbons by a lipoxygenase/hydroperoxide halolyase-mediated transformation in planktonic microalgae

A rapid transformation of eicosapentaenoic acid is initiated upon disintegration of cells of the marine diatom Stephanopyxis turris. In contrast to any other fatty acid cleaving activity known, this diatom releases a blend of chlorinated C8-hydrocarbons in ...

Lipoxygenase-mediated metabolism of storage lipids in germinating sunflower cotyledons and b-oxidation of (9Z,11E,13S)-13-hydroxy-octadeca-9,11-dienoic acid by the cotyledonary glyoxysomes

Institut fur Botanik, Universitat Munster, Schlossgarten 3, 48149, Munster, Germany. During the early stages of germination, a lipid-body lipoxygenase is expressed in the cotyledons of sunflowers (Helianthus annuus L.). In order to obtain evidence for the ...
