Nose and Nasal Cavity01:24

Nose and Nasal Cavity

11.8K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Electron Carriers01:24

Electron Carriers

91.8K
Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be oxidized). They play an essential role in energy production because cellular respiration is contingent on the flow of electrons.
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

Electron Affinity

43.3K
The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion).

Electron Behavior

Overview
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...

Electron Transport Chains01:28

Electron Transport Chains

112.2K
The final stage of cellular respiration is oxidative phosphorylation that consists of two steps: the electron transport chain and chemiosmosis. The electron transport chain is a set of proteins found in the inner mitochondrial membrane in eukaryotic cells. Its primary function is to establish a proton gradient that can be used during chemiosmosis to produce ATP and generate electron carriers, such as NAD+ and FAD, that are used in glycolysis and the citric acid cycle.
The ETC is comprised of...

Area of Science:

  • Analytical Chemistry
  • Biomedical Engineering
  • Sensor Technology

Background:

  • Volatile organic compounds (VOCs) in exhaled breath serve as potential biomarkers for various physiological conditions.
  • Accurate detection and analysis of VOCs are crucial for non-invasive diagnostics.

Purpose of the Study:

  • To investigate the capability of an electronic nose to assess the overall VOC signature in exhaled air.
  • To determine if electronic noses can provide a cumulative measure of VOCs beyond individual compound detection.

Main Methods:

  • Utilized an electronic nose system to analyze exhaled breath samples.
  • Focused on the electronic nose's ability to capture the integrated signal reflecting total VOC concentration.

Main Results:

  • The electronic nose technology demonstrated the ability to verify a cumulative signature of VOCs.
  • The system reflects the overall VOC concentration rather than quantifying specific compounds individually.

Conclusions:

  • Electronic nose technology offers a novel and promising approach for analyzing the complex mixture of VOCs in exhaled breath.
  • This cumulative signature analysis represents a significant advancement in breath analysis technology.
