Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Olfactory receptors for a smell sensor: A comparative study of the electrical responses of rat I7 and human 17-40

, 2011
In this paper we explore relevant electrical properties of two olfactory receptors (ORs), one from rat OR I7 and the other from human OR 17-40, which are of interest for the realization of smell nanobiosensors.

Scalp electroacupuncture targeting trigeminal nerve activation alleviates post‐traumatic stress disorder–induced depression and neuroinflammation in mice

Animal Models and Experimental Medicine, EarlyView.
Scalp electroacupuncture (SA) through activation of the trigeminal pathway exerts anti‐inflammatory, antidepressant, and anxiolytic effects in an animal model of post‐traumatic stress disorder induced by single prolonged stress. This suggests that SA is involved in neuroinflammation and changes in brain‐derived neurotrophic factor protein through the ...

In vitro culture of olfactory epithelial cells from Megalobrama amblycephala and their response to amino acid mixtures and prostaglandin F2α

Frontiers in Cell and Developmental Biology
Olfaction is essential for the survival and reproduction of fish, as it facilitates foraging, food localization, mate selection, and breeding. The in vitro cultured olfactory epithelial cells will provide an important resource for research on how fish ...

Serum p‐tau217 Is a Prognostic Indicator of Cognitive Impairment in Idiopathic REM Sleep Behavior Disorder

Annals of Neurology, EarlyView.
Objective Assess the performance of serum phosphorylated tau 217 (p‐tau217) and neurofilament light chain (NfL) in predicting risk of cognitive impairment or phenoconversion to dementia in individuals with iRBD. Methods We measured serum p‐tau217 and NfL levels by electrochemiluminescence across 4 polysomnographically confirmed iRBD cohorts (n = 300 ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

The Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.
