Objectives: The objective of this study was to investigate whether residual inhibition (RI), which provides information on the relationship between tinnitus and increased spontaneous activity in the auditory system, is a predictor for the success of sound enrichment treatment.
Design: Tinnitus patients were divided into two groups based on whether RI was achieved (RI+) or not (RI-). All participants underwent sound enrichment. Psychosomatic measures (for tinnitus severity, discomfort, attention deficit and sleep difficulties), Tinnitus Handicap Inventory (THI), minimum masking level (MML), and tinnitus loudness level (TLL) results were compared before and at 1, 3, and 6 months after treatment.
Study Sample: Sixty-seven chronic tinnitus patients were divided into two groups based on whether RI was achieved (RI+) or not (RI-). There were 38 patients in the RI+ group and 29 in the RI- group.
Results: There was a statistically significant difference between the groups in psychosomatic measures, THI, MML and TLL scores at the post-treatment 6 months after treatment (p <.05). There was a statistically significant decrease in psychosomatic measures, THI, MML and TLL scores during the treatment period in the RI+ group, but not in the RI- group.
Conclusion: RI may predict the prognosis of tinnitus treatments used in clinics to reduce the spontaneous firing rate of neurons in the central auditory system, and that RI positivity may be a predictor of treatment success in sound enrichment.

Tinnitus is a heterogeneous hearing disorder with no cure at present, but some treatments, such as a combination of counselling and sound therapy, can alleviate the discomfort it causes. The sound therapy efficiency depends on both the type of sound stimulus and the time of exposure. This study describes the fundamentals of a personalized sound therapy that stimulates the auditory system with either continuous or sequential sounds whose spectra are adjusted to the hearing levels of the participants.

Introduction: Acute myeloid leukemia (AML) remains one of the deadliest hematopoietic malignancies. A better understanding of the molecular biology governing AML may lead to improved risk stratification and facilitate the development of novel therapies. Proteins are responsible for much of the biology of cells.

Being deafblind means my perception differs profoundly from those who are conventionally sighted and have non-impaired hearing. A lot of hidden knowledge is to be found in the disparity between these differing experiences that could be of great value in developing assistive technologies that have a broad scope to engage with both disabled and non-disabled users. This article explores the balancing act between sensory loss and the potential inherent in all of us and how this should be part of the design process of haptic assistive technology.

Background: The wild stocks of Pinctada maxima pearl oysters found off the coast of northern Australia are of critical importance for the sustainability of Australia's pearling industry. Locations inhabited by pearl oysters often have oil and gas reserves in the seafloor below and are therefore potentially subjected to seismic exploration surveys. The present study assessed the impact of a simulated commercial seismic survey on the transcriptome of pearl oysters.

Background: Pangolin is one of the most endangered mammals with many peculiar characteristics, yet the understanding of its sensory systems is still superficial. Studying the genomic basis of adaptation and evolution of pangolin's sensory system is expected to provide further potential assistance for their conservation in the future.
Results: In this study, we performed a comprehensive comparative genomic analysis to explore the signature of sensory adaptation and evolution in pangolins.
