The Bronchial Tree01:23

The Bronchial Tree

6.7K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Stereotype Content Model02:16

Stereotype Content Model

15.4K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Competition02:34

Competition

24.8K
When organisms require the same limited resources within an environment, they may have to compete for them. Competition is a net-negative interaction. Even if two competing individuals or populations do not interact directly, the overall fitness of both competitors is lowered as a result of not having full access to the limited resource.

Bacterial Transformation01:33

Bacterial Transformation

59.9K
In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

Solution Equilibrium and Saturation01:59

Solution Equilibrium and Saturation

21.9K
Imagine adding a small amount of sugar to a glass of water, stirring until all the sugar has dissolved, and then adding a bit more. You can repeat this process until the sugar concentration of the solution reaches its natural limit, a limit determined primarily by the relative strengths of the solute-solute, solute-solvent, and solvent-solvent attractive forces. You can be certain that you have reached this limit because, no matter how long you stir the solution, undissolved sugar remains. The...

Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

95.4K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Area of Science:

  • Pulmonology
  • Medical Devices
  • Endoscopic Procedures

Background:

  • Severe persistent asthma lacks effective non-pharmacological treatments.
  • Airway smooth muscle (ASM) contributes to asthma severity.
  • Current treatments primarily rely on medication.

Purpose of the Study:

  • To review the Alair™ Catheter system for bronchial thermoplasty (BT).
  • To describe the BT procedure and patient selection criteria.
  • To discuss pre- and post-procedure patient management.

Main Methods:

  • Controlled heat release using the Alair™ Catheter.
  • Radiofrequency or thermal energy delivery to reduce ASM in bronchi.
  • Endoscopic procedure performed by trained physicians.

Main Results:

  • Significant improvements in asthma symptom control.
  • Reduced rates of severe exacerbations and hospitalizations.
  • Enhanced quality of life and increased work/school days.

Conclusions:

  • Bronchial thermoplasty is an effective endoscopic treatment for severe asthma.
  • Proper patient selection and physician expertise are crucial for optimal outcomes.
  • BT offers a non-pharmacological approach with documented clinical benefits.
