Transient limb ischemia induces remote ischemic preconditioning in vivo [PDF]

, 2002
Background-Ischemic preconditioning reduces local tissue injury caused by subsequent ischemia-reperfusion (IR), but may also have a salutary effect on IR injury of tissues remote from those undergoing preconditioning.

Lipoxygenase-derived eicosanoids in myocardial ischaemia-reperfusion injury: the role of sensory C-fibres and TRPV1 [PDF]

, 2010
PhDIt is well established that the 12-lipoxygenase (12-LOX) pathway of arachidonic acid (AA) metabolism is stimulated within the myocardium by episodes of ischaemia, and there is considerable evidence showing that eicosanoids derived via this pathway ...

Reducing avoidance of learnt fear: Extinction of an imminent threat signal partly decreases costly avoidance to a distal threat signal

Journal of Experimental Psychopathology, 2023
In the interplay of fear and avoidance, not only imminent threat signals that directly predict potential threat evoke avoidance, but also distal threat signals that predict these imminent threat signals.

Ischemic preconditioning attenuates portal venous plasma concentrations of purines following warm liver ischemia in man [PDF]

, 2005
Background/Aims: Degradation of adenine nucleotides to adenosine has been suggested to play a critical role in ischemic preconditioning (IPC). Thus, we questioned in patients undergoing partial hepatectomy whether (i) IPC will increase plasma purine ...

Preconditioning of wavelet BEM by the incomplete Cholesky factorization [PDF]

, 2012
The present paper is dedicated to the preconditioning of boundary element matrices which are given in wavelet coordinates. We investigate the incomplete Cholesky factorization for a pattern which includes also the coefficients of all off-diagonal bands ...

Nearby preconditioning experiments for the Helmholtz equation

, 2021
This code provides a range of experiments for investigating the effectiveness of 'nearby preconditioning' for the heterogeneous Helmholtz equation. This is the version of the software used in the paper 'Analysis of a Helmholtz preconditioning problem ...

Emotional learning retroactively promotes memory integration through rapid neural reactivation and reorganization

eLife, 2022
Neutral events preceding emotional experiences can be better remembered, likely by assigning them as significant to guide possible use in future. Yet, the neurobiological mechanisms of how emotional learning enhances memory for past mundane events remain

Repeating patterns: Predictive processing suggests an aesthetic learning role of the basal ganglia in repetitive stereotyped behaviors

Frontiers in Psychology, 2022
Recurrent, unvarying, and seemingly purposeless patterns of action and cognition are part of normal development, but also feature prominently in several neuropsychiatric conditions.

Interactions between human orbitofrontal cortex and hippocampus support model-based inference.

PLoS Biology, 2020
Internal representations of relationships between events in the external world can be utilized to infer outcomes when direct experience is lacking. This process is thought to involve the orbitofrontal cortex (OFC) and hippocampus (HPC), but there is ...

'Online' integration of sensory and fear memories in the rat medial temporal lobe

eLife, 2019
How does a stimulus never associated with danger become frightening? The present study addressed this question using a sensory preconditioning task with rats.
