Epac1 Alleviates Senescence in Auditory Hair Cells via the Ferroptosis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objectives The aim of this study was to investigate the changes in Epac1 and ferroptosis‐related proteins in aged mice and the House Ear Institute‐Organ of Corti 1 (HEI‐OC1) cells, with the goal of elucidating their potential role in age‐related hearing loss. Methods The expression of Epac1 in the cochlea of C57BL/6J mice was examined by using

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Ontogenetic development of vestibular reflexes in amphibians

Frontiers in Neural Circuits, 2016
Vestibulo-ocular reflexes ensure gaze stability during locomotion and passively induced head/body movements. In precocial vertebrates such as amphibians, vestibular reflexes are required very early at the onset of locomotor activity.

Nocturnal Hypoxemia Burden Correlates With Vestibular Dysfunction in Obstructive Sleep Apnea

Clinical Otolaryngology, EarlyView.
ABSTRACT Introduction Obstructive sleep apnea (OSA) is a potential contributor to vestibular dysfunction, though specific correlating parameters remain unclear. This study aimed to determine whether hypoxemia severity indices correlate quantitatively with caloric slow‐phase eye velocity (SPV), a marker of vestibular function. Methods In a retrospective

The braincase of Malawisaurus dixeyi (Sauropoda: Titanosauria): A 3D reconstruction of the brain endocast and inner ear.

PLoS ONE, 2019
A braincase of the Cretaceous titanosaurian sauropod Malawisaurus dixeyi, complete except for the olfactory region, was CT scanned and a 3D rendering of the endocast and inner ear was generated. Cranial nerves appear in the same configuration as in other

Computed tomographic diagnosis and treatment of pneumolabyrinth in a mare with temporohyoid osteoarthropathy

Equine Veterinary Education, EarlyView.
Summary Pneumolabyrinth, which is the presence of gas within the labyrinth of the inner ear, can be associated with severe peripheral vestibular signs. This report describes a case of pneumolabyrinth in a horse that presented with vestibular ataxia. An 8‐year‐old Quarter Horse mare that presented with cranial nerve VII deficits underwent a standing ...
