Protein Folding

11.7K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
Protein Structure Is Critical to Its Biological Function
Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Molecular Chaperones and Protein Folding

The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Electrodes: Overview

 Electrochemical measurements are conducted in an electrochemical cell composed of various components that control and measure the current and potential. One fundamental component is electrodes, conductive materials that enable electron transfer reactions at their surfaces.
There are two main types of electrodes in electrochemical cells. The first type, known as the working or indicator electrode, has a potential that is sensitive to the analyte's concentration and reacts to changes in...

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Medical Imaging

Background:

  • Cochlear implantation is a common procedure for hearing restoration.
  • While generally safe, complications can arise, impacting device efficacy.
  • Electrode array insertion carries inherent risks.

Observation:

  • Two cases of unusual electrode tip fold-over within the cochlea were identified.
  • This complication occurred during cochlear implant electrode insertion.
  • Both patients required explantation and re-implantation.

Findings:

  • Electrode tip fold-over is a rare but significant complication of cochlear implantation.
  • The use of fine, pre-curved electrodes and insertion tools may increase risk.
  • Systematic postoperative radiological evaluation is crucial for detecting this issue.

Implications:

  • Early detection of electrode fold-over through imaging can prevent further complications.
  • Intraoperative Cone Beam CT may aid in identifying malpositioned electrodes.
  • This finding underscores the need for vigilance in cochlear implant procedures.
