Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

The effect of shadow economy, life expectancy, education, and income on CO2 emissions: an analysis of BRICS countries

open access: yesFrontiers in Environmental Science
Environmental impairment has become one of the leading global concerns since the 1950s, and the drivers of increasing global CO2 emissions have begun to be explored extensively.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Decentralization and the Shadow Economy: Oates Meets Allingham-Sandmo [PDF]

open access: yes
This paper studies the impact of decentralization on the shadow economy. We argue that decentralization may decrease the size of the shadow economy mainly through two transmission channels: (1) Decentralization enhancing public sector efficiency ...

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

open access: yesFEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

Shadow Economy, Rent-Seeking Activities and the Perils of Reinforcement of the Rule of Law [PDF]

open access: yes
An economy is considered where a possibility to seek rents (a particular case of this activity is corruption) exists along with production. A producer is able to hide part of his output from both bribery and taxation.

Regulatory gaps in private supplementary tutoring: international patterns and implications for social protection

open access: yesFrontiers in Education
The present century has brought marked expansion of private supplementary tutoring across countries of all income levels. Tutoring is provided in diverse modes by commercial enterprises, full-time teachers seeking extra incomes, and informal suppliers ...

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

open access: yesFEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

Illuminating the shadows: the role of private supplementary tutoring on student math performance in PISA 2022

open access: yesLarge-scale Assessments in Education
Recent decades have witnessed a global expansion of private supplementary tutoring, known as shadow education—additional support in academic subjects that takes place outside of regular school hours.
