Use of scanning electron microscopy in the cochlea of guinea pigs

Brazilian Journal of Otorhinolaryngology, 2020
Introduction: The use of electron microscopy in the study of the inner ear has allowed us to observe minute details of the hair cells, especially in ototoxicity studies; however, the preparation of this material is a difficult and delicate task.

Behavioral characteristics in sensing mechanism of the Corti

Computational and Structural Biotechnology Journal, 2023
Some experiments can’t be realized because the cochlea’s Corti is the most delicate and complex sensory organ. In this paper, some typical and special behavioral characteristics in the process of sensation were found in medical clinic.

ACETYLCHOLINESTERASE IN THE ORGAN OF CORTI

ACTA HISTOCHEMICA ET CYTOCHEMICA, 1971
Histochemical investigation of acetylcholinesterase in the organ of Corti has been carried out by means of the Karnovsky's method. Acetylcholinesterase is located on the bottom of outer hair cells, tunnel radial fibers (upper), tunnel spiral bundle and inner spiral bundle.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Ultrastructure of the Odontocete Organ of Corti: Scanning and transmission electron microscopy

The Journal of comparative neurology, 2015
The morphological study of the Odontocete organ of Corti, together with possible alterations associated with damage from sound exposure, represents a key conservation approach to assess the effects of acoustic pollution on marine ecosystems.

Secondary Metabolites Composition and Their Histochemical Localization in the Fruit of Piper malgassicum Papini, Palchetti, Gori and Rota Nodari (Piperaceae)

Chemistry &Biodiversity, EarlyView.
ABSTRACT The anatomy, histochemistry, and secondary metabolite composition were investigated on the drupes of Piper malgassicum, one of the components of the spice voatsiperifery pepper. The high amount of piperine recorded with high‐performance liquid chromatography with photodiode‐array detection analysis was localized with histochemistry mainly ...

Prevalence, severity and factors of hearing loss in hemodialysis patients: A cross‐sectional study in Northern Tanzania

Eye &ENT Research, EarlyView.
Abstract Background Hearing loss, affecting 20% of the global population, disproportionately impacts low‐ and middle‐income countries, including Africa. Sensorineural hearing loss (SNHL) is prevalent among hemodialysis patients. In Tanzania, the growing number of hemodialysis patients highlights the need for hearing assessments.

Proteins of the organ of Corti (OC) [PDF]

The Journal of the Acoustical Society of America, 1987
The majority of proteins found to date in OC were identified by immunohistological methods. While these techniques are powerful tools for localization of proteins, they frequently lack satisfactory specificity. Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) is able to demonstrate the presence in the OC of specific subtypes of certain ...
