Gas Chromatography Olfactometry (GC-O) for the (Semi)Quantitative Screening of Wine Aroma

Foods, 2020
This review discusses the different approaches developed by researchers in the last 40 years for the qualitative and semi-quantitative screening of odorants, with special emphasis in wine aroma profiling.

Reverse chemical ecology approach for the identification of an oviposition attractant for Culex quinquefasciatus. [PDF]

, 2018
Pheromones and other semiochemicals play a crucial role in today's integrated pest and vector management strategies. These semiochemicals are typically discovered by bioassay-guided approaches.

Calibration of a Sensor Array (an Electronic Tongue) for Identification and Quantification of Odorants from Livestock Buildings

Sensors, 2007
This contribution serves a dual purpose. The first purpose was to investigate the possibility of using a sensor array (an electronic tongue) for on-line identification and quantification of key odorants representing a variety of chemical groups at two ...

iORandLigandDB: A Website for Three-Dimensional Structure Prediction of Insect Odorant Receptors and Docking with Odorants

Insects, 2023
The use of insect-specific odorants to control the behavior of insects has always been a hot spot in research on “green” control strategies of insects.

Short-term memory trace mediated by termination kinetics of olfactory receptor. [PDF]

, 2016
Odorants activate receptors in the peripheral olfactory neurons, which sends information to higher brain centers where behavioral valence is determined.

Odorant Receptor Inhibition Is Fundamental to Odor Encoding [PDF]

Current Biology, 2019
SUMMARYMost natural odors are complex mixtures of many volatile components, competing to bind odorant receptors (ORs) expressed in olfactory sensory neurons (OSNs) of the nose. To date surprisingly little is known about how OR antagonism shapes neuronal representations in the periphery of the olfactory system.

Decomposition of individual components of bio-organic waste: volatile organic compounds and the impact on health and psycho-emotional state

RUDN Journal of Ecology and Life Safety, 2023
The study considers the impact on the person’s health and psycho-emotional state of unpleasant odors arising from the storage and accumulation of bioorganic waste, including food waste (meat, poultry, fruits and vegetables) and bird droppings. The survey

Optimizing Odorants for Olfactory Training Based on Olfactory Receptor-Ligand Pair Analysis. [PDF]

Laryngoscope
This study employs receptor–ligand interaction analysis and olfactory epithelium transcriptomics to optimize olfactory training (OT). A novel four‐odorant combination (galaxolide, eugenol acetate, [−]‐menthol, geranyl acetate) activates 83.9% of 385 human olfactory receptors (ORs), covering 69.9% of estimated OR expression—significantly outperforming ...
