Anatomy of the Ear01:16

Anatomy of the Ear

11.7K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Total Voids in Concrete01:12

Total Voids in Concrete

480
Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...

Total Internal Reflection Fluorescence Microscopy01:05

Total Internal Reflection Fluorescence Microscopy

13.4K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Co-activators and Co-repressors

8.6K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

tRNA Activation02:26

tRNA Activation

22.9K
Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

Area of Science:

  • Otolaryngology
  • Biomedical Engineering

Background:

  • Two fully implantable hearing devices, the Envoy Esteem and the Carina system, address sensorineural and mixed hearing loss.
  • The Envoy Esteem is indicated for bilateral moderate to severe sensorineural hearing loss with adequate speech discrimination.
  • The Carina system is indicated for moderate to severe sensorineural or mixed hearing loss.

Purpose of the Study:

  • To compare the indications and availability of the Envoy Esteem and Carina systems.
  • To highlight the technological advancements in implantable hearing solutions.

Main Methods:

  • Comparative analysis of device specifications and target patient populations.
  • Review of market availability and regulatory status in the United States.

Main Results:

  • The Envoy Esteem targets moderate to severe sensorineural hearing loss in patients with speech discrimination scores >= 40%.
  • The Carina system accommodates moderate to severe sensorineural or mixed hearing loss.
  • The Envoy Esteem is available in the US; the Carina system is not currently available in the US.

Conclusions:

  • The Envoy Esteem offers an available implantable solution for specific sensorineural hearing loss profiles in the US.
  • The Carina system presents an alternative for a broader range of hearing loss types but lacks US market availability.
