Performances and Fatigue Responses to Weighted Vest Training in Parkour Novices

European Journal of Sport Science, Volume 26, Issue 10, October 2026.
ABSTRACT Weighted vest training has demonstrated benefits for muscle strength, which is critical for parkour performance. However, the acute effects of external loading in this discipline remain poorly understood. This study investigated the impact of weighted vest use during parkour sessions on lower‐limb performance, perceived exertion, and muscle ...

Lesions of the Perirhinal Cortex but Not of the Frontal, Medial Prefrontal, Visual, or Insular Cortex Block Fear-Potentiated Startle Using a Visual Conditioned Stimulus [PDF]

, 1992
The present study is part of an ongoing series of experiments aimed at delineation of the neural pathways that mediate fear-potentiated startle, a model of conditioned fear in which the acoustic startle reflex is enhanced when elicited in the presence of

Reduction of fear-potentiated startle by benzodiazepines in C57BL/6J mice [PDF]

Psychopharmacology, 2010
Anxiety disorders affect 18% of the United States adult population annually. Recent surges in the diagnosis of posttraumatic stress disorder (PTSD) from combat-exposed veterans have prompted an urgent need to understand the pathophysiology underlying this debilitating condition.Anxiety and fear responses are partly modulated by gamma aminobutyric acid ...

Iron and Other Metal Ions in Human Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

Fear-potentiated startle: a review from an aviation perspective

, 2015
Pilot performance following unexpected critical events has been either ineffective or inappropriate in some recent aircraft accidents. The deleterious effects of startle have been identified as causal or contributory in these events.

Men Scare Me More: Gender Differences in Social Fear Conditioning in Virtual Reality

Frontiers in Psychology, 2019
Women nearly twice as often develop social anxiety disorder (SAD) compared to men. The reason for this difference is still being debated. The present study investigates gender differences and the effect of male versus female agents in low (LSA) and high ...

Integrating novel therapeutic strategies in myeloproliferative neoplasms: Driving disease‐directed progress

British Journal of Haematology, Volume 209, Issue 4, Page 1450-1468, October 2026.
Summary Over the past decade, there has been a substantial increase in the diversity and number of therapeutic options for myeloproliferative neoplasms (MPNs). While many remain within the clinical trial arena, the clinician and patient community have seen more approvals reaching the clinic and a rethink on how best we should be approaching these ...

Contextual change after fear acquisition affects conditioned responding and the time course of extinction learning – Implications for renewal research

Frontiers in Behavioral Neuroscience, 2015
Context plays a central role in retrieving (fear) memories. Accordingly, context manipulations are inherent to most return of fear (ROF) paradigms (in particular renewal), involving contextual changes after fear extinction.

Rethinking the Oligodendrocyte Progenitor Cell: One Cell, Many Functions

European Journal of Neuroscience, Volume 64, Issue 7, October 2026.
Oligodendrocyte progenitor cells (OPCs) are increasingly recognised as multifunctional CNS cells rather than mere precursors of myelinating oligodendrocytes. Alongside myelination and remyelination, they contribute to myelin and circuit plasticity, circuit regulation, vascular and blood–brain barrier regulation and neuroimmune modulation.

Prospective Associations between Emotion Dysregulation and Fear-Potentiated Startle: The Moderating Effect of Respiratory Sinus Arrhythmia

Frontiers in Psychology, 2016
Background: Emotion dysregulation has been implicated in the negative outcomes following trauma exposure. A proposed biomarker of emotion dysregulation, respiratory sinus arrhythmia (RSA), has demonstrated associations with trauma-related phenomena, such
