Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Building Resilience in Nonprofit Food Hubs

open access: yesJournal of Agriculture, Food Systems, and Community Development, 2016
Food hubs serve as intermediaries between market actors in the aggregation and distribution of local food. Scholars have identified four common food hub models: retail-driven, nonprofit-driven, producer-driven, and consumer-driven.

Bricolage for Self‐Sufficiency: An Analysis of Alternative Food Networks [PDF]

open access: yesSociologia Ruralis, 2017
AbstractIn this article the bricolage concept is applied to compare the organisational dynamics of two alternative food networks (AFNs) in Riga and Bristol respectively. It is argued that bricolage is a useful concept to understand the dynamics of AFNs. The concept ‘bricolage’ refers to the free use of any materials at hand.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

An Eco-Egalitarian Solution to the Capitalist Consumer Paradox: Integrating Short Food Chains and Public Market Systems

open access: yesAgriculture, 2017
Presently, alternative agri-food networks are in a renaissance, utilizing an economy of proximity to compete against transnational agri-business and food distributors.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Beyond Animal‐Based Diets? Alternative Food Networks and Vegetarianism in the City of Buenos Aires

open access: yesGeo: Geography and Environment
This article aims to advance on a little‐known topic, the relationship between participation in alternative food supply networks (AFN) and the vegetarian condition of consumers in the city of Buenos Aires.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Effective Communication in Alternative Food Networks: A Scoping Review and Implications for Scottish Food Systems

open access: yesJournal of Sustainability
This study conducts a scoping review of primarily European literature (2015-2025) to synthesise reported communication strategies within Alternative Food Networks (AFNs) and derive implications for enhancing local food systems in Scotland. The synthesis
