An Explicit Electron-Vibron Model for Olfactory Inelastic Electron Transfer Spectroscopy

open access: yes, 2019
The vibrational theory of olfaction was posited to explain subtle effects in the sense of smell inexplicable by models in which molecular structure alone determines an odorant's smell.

Heteromeric Anopheline odorant receptors exhibit distinct channel properties. [PDF]

open access: yesPLoS ONE, 2011
BackgroundInsect odorant receptors (ORs) function as odorant-gated ion channels consisting of a conventional, odorant-binding OR and the Orco coreceptor.

Genome-wide identification of candidate chemosensory receptors in the bean bug Riptortus pedestris (Hemiptera: Alydidae) and the functional verification of its odorant receptor co-receptor (Orco) in recognizing aggregation pheromone

open access: yesFrontiers in Physiology, 2023
A sophisticated and sensitive olfactory system plays a vital role in the survival and reproduction of insects. Chemosensory receptors are indispensable for the molecular recognition and discrimination of semiochemicals. Riptortus pedestris is a notorious

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Insect odorant response sensitivity is tuned by metabotropically autoregulated olfactory receptors. [PDF]

open access: yesPLoS ONE, 2013
Insects possess one of the most exquisitely sensitive olfactory systems in the animal kingdom, consisting of three different types of chemosensory receptors: ionotropic glutamate-like receptors (IRs), gustatory receptors (GRs) and odorant receptors (ORs).

The missense of smell: functional variability in the human odorant receptor repertoire. [PDF]

open access: yes, 2013
Humans have ~400 intact odorant receptors, but each individual has a unique set of genetic variations that lead to variation in olfactory perception. We used a heterologous assay to determine how often genetic polymorphisms in odorant receptors alter ...

The olfactory basis of orchid pollination by mosquitoes. [PDF]

open access: yes, 2020
Mosquitoes are important vectors of disease and require sources of carbohydrates for reproduction and survival. Unlike host-related behaviors of mosquitoes, comparatively less is understood about the mechanisms involved in nectar-feeding decisions, or ...

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

open access: yesAdvanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Lack of Pattern Separation in Sensory Inputs to the Olfactory Bulb during Perceptual Learning. [PDF]

open access: yes, 2017
Recent studies revealed changes in odor representations in the olfactory bulb during active olfactory learning (Chu et al., 2016; Yamada et al., 2017).

Early and Sustained Improvements in Sense of Smell With Tezepelumab Treatment in Patients With Chronic Rhinosinusitis With Nasal Polyps (WAYPOINT)

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Loss of smell is a principal symptom of chronic rhinosinusitis with nasal polyps (CRSwNP), affecting health‐related quality of life and posing a safety hazard. Methods WAYPOINT (NCT04851964), a phase 3, multicenter trial in adults with uncontrolled CRSwNP, randomized patients 1:1 to receive tezepelumab 210 mg or placebo ...
