An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

A Grounded Theory on Helping Behavior and Its Shaping Factors

open access: yesGrounded Theory Review: An International Journal, 2006
In social psychology, the attribution model of helping behavior suggests that beliefs of the helping target’s responsibility for the need for help evoke affective motivators such as feelings of pity, sympathy, or anger.

Type theories in category theory

open access: yesCoRR, 2021
We introduce basic notions in category theory to type theorists, including comprehension categories, categories with attributes, contextual categories, type categories, and categories with families along with additional discussions that are not very closely related to type theories by listing definitions, lemmata (with detailed, diagram-rich proofs ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Rethinking Ethnic Identity in the Archaeology of the Ancient Slavs

open access: yesArheološki Vestnik
The archaeology of the ancient Slavs has advanced methodologically but remains divided between scholars who deny the Slavs’ migrations, and those linking material culture directly to ethnic identities.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

The impact of functional training based on clinical nursing pathways informed by evidence-based theory on functional recovery in patients with cerebral hemorrhage

open access: yesFrontiers in Neurology
BackgroundCerebral hemorrhage significantly impacts patients’ neurological function and daily living capabilities. The study investigates the effect of functional training based on clinical nursing pathways informed by evidence-based theory on the ...
