Signalled Delay to Reinforcement in Delayed Matching to Sample

open access: yes, 2012
Five hens were trained on a delayed matching to sample task. The retention intervals started at 0.25 s and were gradually increased until they were 1 s, 2 s, 4 s and 8 s in each session. At the end of training the fifth response to the sample stimulus (

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 ...

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 ...

Distraction of symbolic behavior in regular classrooms

open access: yesFrontiers in Psychology, 2012
The purpose of the present study is to develop more precise methods to explore the interaction between contextual factors in teacher instructions in regular classroom settings and students’ abilities to use symbolic information in the instruction.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Effects of stimuli organization on identity matching-to-sample performances of persons with autism / Desempenho de pessoas com autismo em tarefas de emparelhamento com o modelo por identidade: efeitos da organização dos estímulos

open access: yesPsicologia: Reflexão e Crítica, 2008
This study assessed the performance of 20 persons with autism in an identity matching-to-sample task, using two procedures with different stimuli arrangements and different response requirements.

Transfer of training from one working memory task to another: Behavioural and neural evidence

open access: yesFrontiers in Systems Neuroscience, 2015
N-back working memory (WM) tasks necessitate the maintenance and updating of dynamic rehearsal sets during performance. The delayed matching-to-sample (dMTS) task is another WM task, which in turn involves the encoding, maintenance, and retrieval of ...

Evidence from reaction times for an anticipatory process in symbolic delayed matching-to-sample

open access: yes, 2009
It was predicted that a delay between sample ofset and comparison onset in symbolic delayed matching-to-sample (DMTS) would allow time for the anticipatory retrieval of the correct comparison so that the match/no match status of the presented comparison ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
