Summary
New local drug delivery methods offer innovative ways to protect hearing from damage caused by noise, antibiotics, and chemotherapy. These advanced techniques improve otoprotection for hearing and deafness research.
Area of Science:
- Otolaryngology
- Pharmacology
- Biomedical Engineering
Background:
- Hearing loss is a significant health concern, often resulting from noise exposure, ototoxic medications, and cancer treatments.
- Current otoprotective strategies primarily rely on systemic drug administration, which can have limitations and side effects.
Purpose of the Study:
- To review recent advancements in cochlear drug delivery for otoprotection.
- To explore novel local delivery methods for treating and preventing hearing loss.
Main Methods:
- Review of existing literature on animal models (primarily rodents) for hearing loss protection.
- Analysis of emerging local drug delivery technologies, including nanoparticles, hydrogels, and micropumps.
Main Results:
- Systemic administration of otoprotectants has shown efficacy in animal models against acute hearing loss.
- Novel local delivery systems enable the use of drugs unsuitable for systemic administration and minimize interference with other treatments.
Conclusions:
- Local cochlear drug delivery represents a promising frontier in hearing and deafness research.
- Innovative methods like nanoparticles and cochlear implants offer enhanced otoprotection strategies for various causes of hearing loss.

01:31ATP Yield
79.1K
Cellular respiration produces 30 - 32 ATP per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the electron transport chain (ETC), 4 ATP are gained beforehand (2 from glycolysis and 2 from the citric acid cycle).
The ETC is embedded in the inner mitochondrial membrane and is comprised of four main protein complexes and an ATP synthase. NADH and FADH2 pass electrons to these complexes, which pump protons into the intermembrane space. This distribution of...

02:22Reaction Yield
60.1K
The theoretical yield of a reaction is the amount of product estimated to form based on the stoichiometry of the balanced chemical equation. The theoretical yield assumes the complete conversion of the limiting reactant into the desired product. The amount of product that is obtained by performing the reaction is called the actual yield, and it may be less than or (very rarely) equal to the theoretical yield.

01:16Drug Delivery: Overview
900
The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

01:18Drug Delivery: Enteral Route
1.8K
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

01:29Drug Delivery: Parenteral Route
1.8K
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
