Should red wine be prescribed before a concert? The idea is not as crazy as it sounds if we believe recent studies on Resveratrol, a polyphenol present in red grapes and red wine. This molecule has indeed the ability to reduce the expression of the COX-2 protein and the formation of reactive oxygen species (ROS), two phenomena observed following exposure to intense noise. In fact, when the COX-2 protein is overexpressed, it engages into anti-inflammatory mechanisms; as for ROS, they are produced

Tinnitus Implant: Looking for the code of silence

alt

In February 2013 the first Tinnitus Implant was placed at the Maastricht University Medical Centre+ (MUMC+). The implant was received by a patient that is deaf on one side and suffers from severe tinnitus. Aim is to eliminate tinnitus. Prof. dr. Robert Stokroos, ENT surgeon, performed the implantation. “We are looking for the code of silence.”

In The Netherlands approximately two million people suffer from tinnitus.

Hearing loss is in the genetics

Researchers at Tel Aviv University have discovered that hearing loss may be linked to a genetic mutation.

The researchers found a genetic mutation in two families with hereditary high frequency hearing loss. The mutated gene has not been previously linked to hearing loss. It has NESP4, a protein expressed

A team of American researchers, led by Michelle Hastings (Rosalind Franklin University), has recently developed a technique to rescue hearing in a mouse model of type 1 Usher Syndrome. In 6 to 8% of cases, type 1 is caused by mutation of the Ush1c gene.

They achieved this advance using antisense therapy. By injecting the mice with specific antisens oligonucleotide (ASO) targeting the desired messenger RNA, scientists were able to

Infants at risk for prelingual sensorineural hearing loss

Research

Infants are more susceptible to suffering from sensorineural hearing loss (SNHL), particularly NICU newborns, according to an Italian study. The authors found a high SNHL prevalence (10.03%) in their cohort, with 33% of NICU newborns having a greater chance of developing SNHL because of the presence of multiple risk factors (or=1.33) and their interaction. As the number of coexisting risk factors increases, the prevalence of SNHL

Detecting conductive hearing loss

Conductive hearing loss (CHL) in young infants can be detected well with Wideband reflectance (WBR) or tympanometry using probe frequencies of 678 and 1000 Hz, according to a joint study of American researchers. The goal of the study was to evaluate the effectiveness of tympanometry and WBR in detecting conductive hearing loss (CHL) in young infants. The researchers found that

First discovery of lipids in auditory system of an insect

Researchers have discovered a lipid synthesizing organ in the auditory system of a tree weta, an insect endemic to New Zealand, which has a fossil record dating back 270 million years. Very little is known about the hearing abilities and modes of communication of most weta species. Studies and observations indicate they communicate using both far-field hearing and vibration. Weta produce sound by stridulation and the calls produced are broadband with frequency peaks between 2–14 kHz, depending on the type of stridulation being produced. Weta are thought to produce four different behavioural stridulations. However, a complete repertoire of sound is only known for one weta species, Hemideina crassidens. The aim of this research project was to

AT decreases care burden

A Canadian-American team of researchers have conducted the first experimental study which demonstrates that the provision of assistive technology decreases care burden. “If confirmed and extended by subsequent research, the findings will have significant policy and practice implications and may enable health care providers to advocate for improved access to AT provision and related follow-up services,” according to the study. This study was a delayed intervention, randomized control trial. Baseline data were collected
