Smell as evidence of disease has been long used, dating back to Hippocrates around 400 years BCE. [1] It is still employed with a focus on volatile organic compounds (VOCs) found in body odor. [ 2 ] VOCs are carbon-based molecular groups having a low molecular weight, secreted during cells' metabolic processes. [ 3 ]
The DeGennaro Lab seeks to determine the odors and olfactory receptors that contribute to host detection in mosquitoes, analyze nectar-seeking behavior and examine vector ecology. [3] DeGennaro also intends to establish a model for coral symbiosis and chemosensation using the upside-down jellyfish, Cassiopea xamachana , in order to study new ...
Chemical Senses is a peer-reviewed scientific journal covering all aspects of chemoreception, including taste, smell, vomeronasal, and trigeminal chemoreception in humans and other animals. It is published by Oxford University Press and the editor-in-chief is Steven D. Munger ( University of Florida ).
The vibration theory of smell proposes that a molecule's smell character is due to its vibrational frequency in the infrared range. This controversial theory is an alternative to the more widely accepted docking theory of olfaction (formerly termed the shape theory of olfaction), which proposes that a molecule's smell character is due to a range of weak non-covalent interactions between its ...
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
What was up with this unusual body smell of mine, I wondered. “When we are isolated and confined to certain places, the diversity of our microbiome is reduced, and certain microbes can over-grow ...
Monell was founded in 1968. The center's mission is to advance knowledge of the mechanisms and functions of the chemical senses. Knowledge gained from Monell’s research is relevant to issues related to public health, national health policy, and quality of life, including studies of obesity, diabetes, hypertension, pediatric health, occupational safety, environmental interactions, and ...
Haze and a chlorine odor are likely to descend upon Atlanta on Thursday as officials struggle to contain the fallout from a chemical lab fire that ignited Sunday.. Air quality monitoring detected ...
