L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Ownership structure and the operating performance of Hungarian firms [PDF]

open access: yes, 2002
This paper uses firm-level data on 162 large Hungarian enterprises to analyse the relationship between ownership structure and corporate performance in 1998 and 1999. Cross-sectional regressions are run for each of these years using the return on assets (

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

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 ...

Public versus private ownership : the current state of the debate [PDF]

open access: yes
At the heart of the debate about public versus private ownership lie three questions: 1) Does competition matter more than ownership? 2) Are state enterprises more subject to welfare-reducing interventions by government than private firms are?

Ownership, Control and Corporate Performance after Large-Scale Privatization [PDF]

open access: yes
We analyze the effects of ownership type and concentration on performance of a population of firms in a model large-scale privatization economy. Using specifications based on first-differences and unique instrumental variables, we find that few types of ...
