Protein Folding

11.5K
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

19.8K
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.

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

520
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Mitral Valve Prolapse II: Assessment and Management

574
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Summary
This summary is machine-generated.

Dynamic tonsillar prolapse can mimic vocal cord dysfunction, causing breathing issues in children. Adenotonsillectomy effectively resolves these symptoms, improving upper airway obstruction.

Area of Science:

  • Pediatric Otolaryngology
  • Respiratory Medicine
  • Sleep Medicine

Background:

  • Paradoxical vocal fold movement dysfunction (PVFMD) presents with inspiratory stridor and dyspnea, often difficult to diagnose due to episodic symptoms.
  • Upper airway obstruction can arise from various sources, including adenotonsillar hypertrophy, mimicking PVFMD.

Purpose of the Study:

  • To evaluate pediatric patients with symptoms suggestive of PVFMD.
  • To investigate dynamic upper airway obstruction caused by adenotonsillar hypertrophy and prolapse.

Main Methods:

  • Retrospective chart review of pediatric patients diagnosed with exertional dynamic tonsillar prolapse.
  • Analysis of clinical characteristics, spirometry, and response to adenotonsillectomy.

Main Results:

  • Seven patients with exertional dyspnea and respiratory distress underwent adenotonsillectomy.
  • All patients had significant oropharyngeal obstruction due to tonsillar hypertrophy and prolapse.
  • No patients were diagnosed with exercise-induced paradoxical vocal fold dysfunction; all showed symptomatic improvement post-surgery.

Conclusions:

  • Dynamic tonsillar prolapse can cause exertional dyspnea and airway resistance, mimicking PVFMD.
  • Adenotonsillectomy is an effective treatment for symptomatic relief in these cases.
