Summary
Cochlear implants offer effective auditory rehabilitation for deafness, restoring hearing through electrical nerve stimulation. Future advancements aim to create a "bionic ear" for more natural hearing restoration.
Area of Science:
- Otorhinolaryngology
- Biomedical Engineering
- Neuroscience
Background:
- Cochlear implants are the primary treatment for sensory deafness, restoring hearing by converting sound into electrical signals for the auditory nerve.
- Rapid technological advancements have significantly improved cochlear implant performance, enabling open-set speech understanding and telephone use.
Purpose of the Study:
- To review the current state and future directions of cochlear implant technology for auditory rehabilitation.
- To highlight advancements in surgical techniques, electrode technology, and biological therapies for improved hearing outcomes.
Main Methods:
- Standardized diagnostic and surgical procedures adapted for individual needs.
- Technological upgrades focusing on electrode-nerve interfaces and increased electrical contacts.
- Exploration of biological therapies including stem cells, local drug delivery, and gene therapy.
Main Results:
- Cochlear implants provide open-set speech understanding in most patients, including children with early detection and intervention.
- Standardized procedures and technology upgrades enhance performance and enable telephone use.
- Future developments promise improved speech coding, robot-assisted surgery, and biological therapies for enhanced hearing restoration.
Conclusions:
- Cochlear implants are a powerful tool for rehabilitating sensory deafness, with significant potential for further improvement.
- Future innovations in electrode technology, surgery, and biological therapies will advance the concept of the "bionic ear."
- Despite a large eligible population, underutilization remains, highlighting the need for broader adoption of this technology.

Parenteral drug delivery systems play a crucial role in modern therapeutics by enabling the direct administration of drugs into the systemic circulation, bypassing the gastrointestinal tract. These systems are particularly valuable for poorly absorbed oral medications that are unstable in the digestive environment or require rapid onset or sustained therapeutic levels. Delivery is achieved through intravenous, intramuscular, or subcutaneous routes, each selected based on the drug's properties...

02:57The Sense of Self: Reflected Self-Appraisal and Social Comparison
56.2K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

50.4K
After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
