A medullary hub for controlling REM sleep and pontine waves
Nature Communications, 2023 Rapid-eye-movement (REM) sleep is a distinct behavioral state associated with vivid dreaming and memory processing. Phasic bursts of electrical activity, measurable as spike-like pontine (P)-waves, are a hallmark of REM sleep implicated in memory ...

A circadian clock regulates efflux by the blood-brain barrier in mice and human cells
Nature Communications, 2021 The blood-brain barrier is critical for neural function. Here, the authors show that efflux of xenobiotics through the BBB follows a circadian rhythm in mice and human cells.

Advanced Science, EarlyView.Biological rhythms coordinate physiology, from genes to behavior. Study of circadian rhythms in brain tissue is constrained by limited throughput and spatial and temporal information quality. A new platform for high‐throughput, long‐term multiplexed fluorescent live imaging of circadian rhythms in brain slices is introduced.

Scientific Reports, 2017 The central circadian pacemaker (Suprachiasmatic Nuclei, SCN) maintains the phase relationship with the external world thanks to the light/dark cycle. Light intensity, spectra, and timing are important for SCN synchronisation.

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

The Role of HUWE1 on Mouse Neural Cell Proliferation and Zebrafish Neurodevelopment
Medicine Bulletin, EarlyView.ABSTRACT The HECT, UBA, and WWE domain‐containing E3 ubiquitin protein ligase 1 (HUWE1) gene is located on the X chromosome and has been implicated in neurodevelopmental disorders. However, the mechanisms by which HUWE1 dosage affects nervous system development remain poorly understood. In this study, we demonstrate that HUWE1 overexpression suppresses
