Eye Behaviour in a Targeting Task in Children with ADHD: Linkage to a Level of Attention

open access: yesBioengineering
Children with attention deficit hyperactivity disorder (ADHD) often exhibit different oculomotor behavior compared to their typically developing peers. Research shows that eye movement patterns can provide important information about attention mechanisms.

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 ...

Inhibition of ribulose-P2 carboxylase/oxygenase by fluoride

open access: yes, 1984
Fluoride is a potent inhibitor of both reactions of ribulose-P2 carboxylase/oxygenase. Inhibition is almost totally competitive with respect to CO2, but uncompetitive with respect to ribulose-P2 Inhibition of photosynthesis after exposure to HF may ...

The Vitis vinifera receptor VvLYK6 negatively regulates chitin-triggered immune responses and promotes fungal infections

open access: yesFrontiers in Plant Science
IntroductionBotrytis cinerea is recognized as one of the most damaging fungal pathogens affecting grapevine (Vitis vinifera), directly impacting both grape yield and wine quality. Identifying new genes involved in the interaction between V.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Effects of focal frontal lesions on response inhibition

open access: yes, 2007
This study examined the performance of 38 normal subjects and 43 patients with focal lesions of the frontal lobes on a simple go-nogo task where the probability of the nogo stimulus was either 75% or 25%.

Inhibition of diacylglycerol–sensitive TRPC channels by synthetic and natural steroids

open access: yes, 2012
TRPC channels are a family of nonselective cation channels that regulate ion homeostasis and intracellular Ca2+ signaling in numerous cell types. Important physiological functions such as vasoregulation, neuronal growth, and pheromone recognition have ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Characterization of the ligand binding pocket of the virulence regulator Rns, a member of the AraC/XylS family of transcription factors

open access: yesmSphere
Diarrheal disease caused by Gram-negative enteric pathogens, such as enterotoxigenic Escherichia coli (ETEC), Vibrio cholerae, Shigella spp., and Salmonella spp., is a leading cause of morbidity and mortality of children, especially in low resource ...
