Structure and function of the mammalian middle ear. II: Inferring function from structure. [PDF]

open access: yes, 2015
Anatomists and zoologists who study middle ear morphology are often interested to know what the structure of an ear can reveal about the auditory acuity and hearing range of the animal in question.

Diagnostic Performance of Endoscopic and Microscopic Procedures for Identifying Different Middle Ear Structures and Remaining Disease in Patients with Chronic Otitis Media: A Prospective Cohort Study. [PDF]

open access: yesPLoS ONE, 2015
BACKGROUND:The diagnostic performance of endoscopic and microscopic procedures for detecting diseases of the middle ear in patients with chronic otitis media (COM) has rarely been investigated. This study was conducted to compare the performance of these

Immunohistochemical localization of d‐β‐aspartic acid in congenital and acquired middle ear cholesteatoma

open access: yesLaryngoscope Investigative Otolaryngology, 2022
Objective/Hypothesis Middle ear cholesteatoma is characterized by abnormal growth of the keratinizing squamous epithelium of the temporal bone. d‐β‐aspartic acid is the major isomer of d‐aspartic acid found in elderly tissue.

Capillary hemangioma of tympanic cleft [PDF]

open access: yes, 2009
We present an extensive capillary hemangioma of right ear in an 11-year-old child involving external auditory canal, middle ear and mastoid. Patient was presented with chronic purulent discharge and aural mass in right ear. The Computarize tomography (CT)

Cochlear-bone wave can yield a hearing sensation as well as otoacoustic emission

open access: yes, 2014
A hearing sensation arises when the elastic basilar membrane inside the cochlea vibrates. The basilar membrane is typically set into motion through airborne sound that displaces the middle ear and induces a pressure difference across the membrane.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma

open access: yesMolecular Oncology, EarlyView.
We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

Hyperostotic tympanic bone spicules in domestic and wild animal species [PDF]

open access: yes, 2016
Hyperostotic tympanic bone spicules (HTBS), or "mucoperiosteal exostoses" (ME, syn.) are small, globular (>= 1 mm in diameter), mostly stalked and drumstick-like, bony structures, which arise from the inner wall of the tympanic bulla and project into the
