Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

GABA(B) receptor-mediated modulation of synaptic plasticity in the lateral amygdala [PDF]

open access: yes, 2005
Fear conditioning, one of the most powerful and widely used methods to investigate the mechanisms of associative learning in animals, involves the pairing of an aversive stimulus such as a foot-shock (the unconditioned stimulus; US) with a neutral ...

Effects of local anesthesia of the cerebellum on classical fear conditioning in goldfish

open access: yesBehavioral and Brain Functions, 2010
Background Besides the amygdala, of which emotion roles have been intensively studied, the cerebellum has also been demonstrated to play a critical role in simple classical fear conditioning in both mammals and fishes.

Suppression of lung adenocarcinoma migration through organelle alkalization by human lactoferrin – albumin fusion

open access: yesFEBS Open Bio, EarlyView.
This paper reveals how human lactoferrin–albumin fusion (hLF‐HSA) potently suppresses lung adenocarcinoma cell migration. hLF‐HSA upregulates NHE7, leading to Golgi alkalization, disruption of the Golgi secretome, downregulation of MMP1, and reversal of EMT. These findings suggest a novel Golgi‐targeting strategy to suppress cancer cell migration.

Mindfulness and fear conditioning

open access: yes, 2016
During mindfulness-based interventions participants can be invited to bring aversive stimuli to mind while practicing mindfulness. This is thought to help the stimuli become less aversive.

Modeling fear‐conditioned bradycardia in humans

open access: yesPsychophysiology, 2016
AbstractAcross species, cued fear conditioning is a common experimental paradigm to investigate aversive Pavlovian learning. While fear‐conditioned stimuli (CS+) elicit overt behavior in many mammals, this is not the case in humans. Typically, autonomic nervous system activity is used to quantify fear memory in humans, measured by skin conductance ...

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

open access: yesFEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Correlational relationship between shock intensity and corticosterone secretion on the establishment and subsequent expression of contextual fear conditioning

open access: yes, 1998
A role for corticosterone in the consolidation of contextual fear conditioning has previously been proposed. In this study, physiological evidence was found to support this view.

Delay and trace fear conditioning in a complex virtual learning environment - neural substrates of extinction

open access: yesFrontiers in Human Neuroscience, 2014
Extinction is an important mechanism to inhibit initially acquired fear responses. There is growing evidence that the ventromedial prefrontal cortex (vmPFC) inhibits the amygdala and therefore plays an important role in the extinction of delay fear ...

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...
