Efficacy and Safety of Dexmedetomidine‐Esketamine Versus Dexmedetomidine Alone as Premedication for Pediatric Anesthesia Induction: A Systematic Review, Meta‐Analysis, and Trial Sequential Analysis

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Background Emergence delirium (ED) is a common complication in pediatric anesthesia. Although intranasal dexmedetomidine (DEX) is widely used, its application is constrained by a slow onset, residual risk of ED in some patients, and risks such as bradycardia and hypotension.

The "Ram Effect": A "Non-Classical" Mechanism for Inducing LH Surges in Sheep [PDF]

open access: yes, 2016
During spring sheep do not normally ovulate but exposure to a ram can induce ovulation. In some ewes an LH surge is induced immediately after exposure to a ram thus raising questions about the control of this precocious LH surge.

Parkinson's disease dementia: a neural networks perspective. [PDF]

open access: yes, 2015
In the long-term, with progression of the illness, Parkinson's disease dementia affects up to 90% of patients with Parkinson's disease. With increasing life expectancy in western countries, Parkinson's disease dementia is set to become even more ...

Human brain matters: Navigating the neuropathology of COVID‐19

open access: yesBrain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Glucocorticoids and HPA axis regulation in the stress–obesity connection: A comprehensive overview of biological, physiological and behavioural dimensions

open access: yesClinical Obesity, Volume 15, Issue 2, April 2025.
Summary Chronic stress, characterized by increased long‐term exposure to the glucocorticoid hormone cortisol, is increasingly linked to obesity development. Still, various knowledge gaps persist, including on underlying pathophysiological mechanisms. The aim of the current review is to provide the latest insights on the connection between stress and ...

Locus Coeruleus and Dopamine-Dependent Memory Consolidation

open access: yesNeural Plasticity, 2017
Most everyday memories including many episodic-like memories that we may form automatically in the hippocampus (HPC) are forgotten, while some of them are retained for a long time by a memory stabilization process, called initial memory consolidation ...

Iodine-123 labeled reboxetine analogues for imaging of noradrenaline transporter in brain using single photon emission computed tomography [PDF]

open access: yes, 2012
Preliminary investigation of the radioiodinated (S,S)-reboxetine analogue, 123I-INER, in baboons showed this tracer to have promise for imaging the noradrenaline transporter (NAT) using single photon emission computed tomography (SPECT).

Regulation of PHOX2B gene expression by the long non‐coding natural antisense RNA PHOX2B‐AS1

open access: yesThe FEBS Journal, EarlyView.
PHOX2B is a transcription factor essential for autonomic nervous system development. We identify and characterize PHOX2B‐AS1, a human long non‐coding antisense transcript at the PHOX2B locus, along with its murine counterpart. Our findings reveal bidirectional transcription and reciprocal regulation: PHOX2B activates PHOX2B‐AS1, whereas PHOX2B‐AS1 ...

Noradrenergic-dependent functions are associated with age-related locus coeruleus signal intensity differences

open access: yesNature Communications, 2020
Alterations of locus coeruleus signal intensity have been associated with functional changes in health and disease. Here, the authors tested a pre-registered hypothesis on a large number of subjects as part of the Cam-CAN consortium.
