Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

open access: yesMolecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

A multi-agent reinforcement learning model of common-pool resource appropriation [PDF]

open access: yes, 2017
Humanity faces numerous problems of common-pool resource appropriation. This class of multi-agent social dilemma includes the problems of ensuring sustainable use of fresh water, common fisheries, grazing pastures, and irrigation systems. Abstract models

The role of institutions in community wildlife conservation in Zimbabwe

open access: yesInternational Journal of the Commons, 2018
Institutions play a significant role in stabilizing large-scale cooperation in common pool resource management. Without restrictions to govern human behaviour, most natural resources are vulnerable to overexploitation.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Characterizing Actions in a Dynamic Common Pool Resource Game [PDF]

open access: yesGames, 2018
We conducted a dynamic common pool resource experiment and found large differences among groups in the total benefits (surplus) obtained from the resource. To shed light on the factors underlying the differences, we characterized individual appropriation decisions as irresponsible, sustainable, or constructive, and defined a measure of the intensity of

The appropriation of endogenously provided common-pool resources [PDF]

open access: yes, 2013
Because game theory suggests that the origin of a common-pool resource should not affect appropriation behavior, experimental studies of appropriation from common-pool resources generally presume resources are exogenously provided.

Natural resource governance in lower Omo, Ethiopia – negotiation processes instead of property rights and rules?

open access: yesInternational Journal of the Commons, 2017
Research on common-pool resources in the last 30 years has hinged on concepts such as rules and property rights for understanding how access and use of natural resources is managed by communities and other actors.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Stable Sampling Equilibrium in Common Pool Resource Games [PDF]

open access: yesGames, 2015
This paper reconsiders evidence from experimental common pool resource games from the perspective of a model of payoff sampling. Despite being parameter-free, the model is able to replicate some striking features of the data, including single-peaked frequency distributions, the persistent use of strictly dominated actionsand stable heterogeneity in ...

Commons management and ecotourism: Ethnographic evidence from the Amazon

open access: yesInternational Journal of the Commons, 2009
The paper evaluates the relationship between ecotourism and commons management. Social and economic impacts of ecotourism in an indigenous village in the Peruvian Amazon are considered in relation to opportunities for collective action to manage common ...
