Nitric Oxide Signaling Pathway01:28

Nitric Oxide Signaling Pathway

6.3K
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

3.6K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Oxidation Numbers

42.6K
In redox reactions, the transfer of electrons occurs between reacting species. Electron transfer is described by a hypothetical number called the oxidation number (or oxidation state). It represents the effective charge of an atom or element, which is assigned using a set of rules.

Pyruvate Oxidation01:15

Pyruvate Oxidation

168.8K
After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions ensure that pyruvate can enter the next metabolic pathway so that energy stored in the pyruvate molecules can be harnessed by the cells.
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

  • Pulmonology and Allergy

Background:

  • Fractional concentration of exhaled nitric oxide (FENO) is a key biomarker for allergic airway inflammation.
  • Its noninvasive nature and ease of measurement make it valuable in respiratory disease management.

Purpose of the Study:

  • To review the utility of FENO in diagnosing and managing respiratory diseases, with a focus on asthma.
  • To highlight FENO's role in predicting treatment response and preventing exacerbations.

Main Methods:

  • Literature review of studies investigating FENO in respiratory diseases, particularly asthma.
  • Analysis of research supporting FENO's application in diagnosis, steroid responsiveness prediction, and exacerbation management.

Main Results:

  • FENO is supported by numerous studies for aiding asthma diagnosis.
  • Evidence suggests FENO can predict steroid responsiveness in asthma patients.
  • FENO measurement assists in preventing exacerbations by guiding medication dosage and adherence.

Conclusions:

  • FENO is a valuable, noninvasive tool in the management of asthma.
  • Its application extends to guiding therapy and monitoring patient adherence.
  • FENO plays a significant role in personalized respiratory medicine.
