The “European Refugee Crisis” as the Crisis of Liberal Tolerance: Three Modalities of Liberal Exclusion

open access: yesAlternatif Politika, 2022
This article examines European residential responses to migrations after 2015. The literature meticulously analyzes their historically-contextually changing variances and inner diversities while imposing a binary view: the anti-immigration response is ...

Mutation in ntrC gene leading to the derepression of nitrogenase synthesis in Rhodobacter sphaeroides [PDF]

open access: yesFEMS Microbiology Letters, 2006
The Rhodobacter sphaeroides mutants Drn12 and Drn21 derepressed for nitrogenase synthesis in the presence of ammonia and impaired in utilization of certain nitrogen sources have been analyzed. Both mutants show a low level of expression of the glnBA operon.

NTRC Plays a Crucial Role in Starch Metabolism, Redox Balance, and Tomato Fruit Growth [PDF]

open access: yes, 2019
NADPH-thioredoxin reductase C (NTRC) forms a separate thiol-reduction cascade in plastids, combining both NADPHthioredoxin reductase and thioredoxin activities on a single polypeptide.

Thioredoxin system modulates metabolic and stomatal responses to elevated CO2 in Arabidopsis

open access: yesNew Phytologist, EarlyView.
Integrative model of extraplastidial NADPH‐dependent thioredoxin reductase/thioredoxin system‐mediated regulation of stomatal function, redox homeostasis, and metabolic responses under ambient and elevated CO2 in Arabidopsis thaliana. Summary The NADPH‐dependent thioredoxin reductase/thioredoxin (NTR/TRX) system plays a central role in maintaining ...

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

open access: yesmLife, Volume 5, Issue 3, Page 312-324, June 2026.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Functional and structural insights into cyanobacterial CO2 concentrating mechanisms: from compartmentalization to regulation

open access: yesThe Plant Journal, Volume 126, Issue 5, June 2026.
Significance Statement Life on Earth depends on photosynthetic CO2 fixation via the Calvin–Benson–Bassham cycle to form organic carbon. This process evolved first in cyanobacteria and was later conveyed to eukaryotes, giving rise to plastids in algae and plants. To cope with low atmospheric CO2 concentrations that developed over the course of evolution,

Situating the Russian Advocacy of Traditional Values in the Geopolitical Context

open access: yesAlternatif Politika, 2023
As epitomized by the invasion of Ukraine, the lasting geopolitical power struggle between the West and the rising nations, including Russia, has been dragging the international system towards polarization again. Its epicenter lies in the contest over the
