Using Xenopus to discover new candidate genes involved in BOR and other congenital hearing loss syndromes

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 342, Issue 3, Page 212-240, May 2024.
Branchio‐oto‐renal syndrome (BOR), which results in hearing loss and craniofacial defects, is caused by mutations in either SIX1, SIX5, or EYA1. However, the underlying genetic cause is unknown in about 50% of patients. We used transcriptomics, proteomics, and yeast 2‐hybrid approaches in Xenopus embryos to identify new putative candidate genes of BOR.

Newborn hearing screening with transient evoked otoacoustic emissions and automatic auditory brainstem response [PDF]

Einstein (São Paulo), 2008
Objective: The aim of the present investigation was to check Transient Evoked Otoacoustic Emissions and Automatic Auditory Brainstem Response tests applied together in regular nurseries and Newborn Intensive Care Units (NICU), as well as to describe and ...

Contralateral inhibition of click- and chirp-evoked human compound action potentials [PDF]

, 2017
Cochlear outer hair cells (OHC) receive direct efferent feedback from the caudal auditory brainstem via the medial olivocochlear (MOC) bundle. This circuit provides the neural substrate for the MOC reflex, which inhibits cochlear amplifier gain and is ...

Enhancement and suppression of spontaneous emission and light scattering by quantum degeneracy [PDF]

, 2000
Quantum degeneracy modifies light scattering and spontaneous emission. For fermions, Pauli blocking leads to a suppression of both processes. In contrast, in a weakly interacting Bose-Einstein condensate, we find spontaneous emission to be enhanced, while light scattering is suppressed.

Finnish paediatric study found a low incidence of bacterial meningitis from 2011 to 2018 but a substantial proportion of nosocomial meningitis

Acta Paediatrica, Volume 113, Issue 2, Page 327-335, February 2024.
Abstract Aim This study examined the predisposing factors, clinical picture, bacterial aetiology and clinical outcomes of infants and children with bacterial meningitis (BM). Methods The medical records of patients under 16 years of age, treated by Turku University Hospital, Finland, from 2011 to 2018, were screened for meningitis using the ...

Response level of the transient-evoked otoacoustic emissions on infants having a gastroesophageal reflux

International Archives of Otorhinolaryngology, 2011
Introduction: The transient-evoked otoacoustic emissions (TEOAE) have been the most widespread technique to perform neonatal hearing screening. Scrutinizing their measures by way of an association with other alterations that may impair the infant's ...

Prolonged Exposure of CBA/Ca Mice to Moderately Loud Noise Can Cause Cochlear Synaptopathy but Not Tinnitus or Hyperacusis as Assessed With the Acoustic Startle Reflex

Trends in Hearing, 2018
Hearing loss changes the auditory brain, sometimes maladaptively. When deprived of cochlear input, central auditory neurons become more active spontaneously and begin to respond more strongly and synchronously to better preserved sound frequencies.

A Comprehensive Three-Dimensional Model of the Cochlea [PDF]

, 2003
The human cochlea is a remarkable device, able to discern extremely small amplitude sound pressure waves, and discriminate between very close frequencies.

Effects of Local Fields on Spontaneous Emission in Dielectric Media [PDF]

, 2000
The local-field renormalization of the spontaneous emission rate in a dielectric is explicitly obtained from a fully microscopic quantum-electrodynamical, many-body derivation of Langevin-Bloch operator equations for two-level atoms embedded in an absorptive and dispersive, linear dielectric host.

Beckwith–Wiedemann syndrome with multiple hepatic and cutaneous hemangiomas in a female patient of Albanian origin: Diagnostic and therapeutic considerations

American Journal of Medical Genetics Part A, Volume 194, Issue 1, Page 88-93, January 2024.
Abstract We describe a 2‐month‐old female infant with macroglossia, macrosomia, omphalocele, neonatal hypoglycemia, earlobe creases, low nasal bridge, midface retrusion, syndromic facies and multiple cutaneous and hepatic hemangiomas (HH). Genetic evaluation confirmed the diagnosis of Beckwith–Wiedemann Syndrome (BWS) with mosaic uniparental disomy 11 ...
