Hearing Status in Neonatal Hyperbilirubinemia by Auditory Brain Stem Evoked Response and Transient Evoked Otoacoustic Emission [PDF]

Acta Medica Iranica, 2011
Hyperbilirubinemia at neonatal period is one of the major deteriorating factors of the auditory system. If left untreated, it may cause certain cerebral damage. This study aims to evaluate the impact of hyperbilirubinemia on the hearing of neonate.

Spontaneous emission of polaritons from a Bose-Einstein condensate [PDF]

Eur. Phys. J. D 12, 241-253 (2000), 1999
We study the spontaneous emission of a partially excited Bose-Einstein condensate composed of two-level atoms. The formation of polaritons induced by the ground-state part of the condensate leads to an avoided crossing in the photon spectrum. This avoided crossing acts similarly to a photonic band gap and modifies the spontaneous emission rate.

Impacts of perinatal nicotine exposure on nicotinic acetylcholine receptor expression and glutamatergic synaptic transmission in the mouse auditory brainstem

The Journal of Physiology, Volume 603, Issue 9, Page 2857-2876, 1 May 2025.
Abstract figure legend Developmental nicotine exposure is known to cause a myriad of health defects including auditory processing deficits. In human and animal studies, nicotine exposure can lead to impaired auditory temporal processing and disrupted glutamate synapse development within the auditory cortex.

Loss‐of‐Function CARS1 Variants in a Patient With Microcephaly, Developmental Delay, and a Brittle Hair Phenotype

Molecular Genetics &Genomic Medicine, Volume 13, Issue 2, February 2025.
We report a patient with biallelic cysteinyl‐tRNA synthetase (CARS1) variants that presents with hepatopathy, hypothyroidism, short stature, developmental delay, microcephaly muscular hypotonia, brittle hair, and ataxia. Functional studies revealed that the identified variants cause hypomorphic and loss‐of‐function effects, expanding the allelic and ...

Otoacoustic emissions in neonates exposed to smoke during pregnancy

Brazilian Journal of Otorhinolaryngology, 2021
Introduction: The toxic substances present in cigarette smoke can damage cochlea hair cells. This effect has been investigated by measuring otoacoustic emissions.

The Survey of Neonates in Pomerania: Design, Recruitment and Follow‐Up of the Second Cohort, 2013–2017

Paediatric and Perinatal Epidemiology, Volume 39, Issue 2, Page 207-217, February 2025.
ABSTRACT Background The Survey of Neonates in Pomerania (SNiP) is a birth cohort study conducted in Western Pomerania, Germany. SNiP‐I recruited participants at birth between the years 2002 and 2008 (5801 inclusions). Since SNiP‐I, population sociodemographic characteristics and the prevalence of early exposures, including overweight and gestational ...

Spectral instabilities of spontaneous otoacoustic emissions. [PDF]

The Journal of the Acoustical Society of America, 1991
Attempts to model spontaneous otoacoustic emissions (SOAEs) have generally posited as self-sustained oscillators that are perturbed by noise [cf. Talmadge etal., J. Acoust. Soc. Am. 89, 2391–2399 (1991)]. The critical data against which to evaluate such models, based on short-term statistical variations in the frequency and amplitude, have been ...
