Chemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality. [PDF]

open access: yes, 2015
Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of ...

Machine Learning Approaches for GC–MS Data Interpretation in Flavour and Fragrance Analysis

open access: yesFlavour and Fragrance Journal, EarlyView.
The review explores machine learning integration in GC‐MS data analysis for the fragrance and flavour industry, highlighting recent advances and techniques in a context constrained by data scarcity and intellectual property concerns. ABSTRACT This review explores the integration of machine learning (ML) in the analysis of mass spectrometry data ...

Odors: from chemical structures to gaseous plumes [PDF]

open access: yes, 2020
We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their ...

The genetic basis of host preference and resting behavior in the major African malaria vector, Anopheles arabiensis [PDF]

open access: yes, 2016
Malaria transmission is dependent on the propensity of Anopheles mosquitoes to bite humans (anthropophily) instead of other dead end hosts. Recent increases in the usage of Long Lasting Insecticide Treated Nets (LLINs) in Africa have been associated ...

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

open access: yesFlavour and Fragrance Journal, EarlyView.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.

Olfactory discrimination largely persists in mice with defects in odorant receptor expression and axon guidance

open access: yesNeural Development, 2012
Background The defining feature of the main olfactory system in mice is that each olfactory sensory neuron expresses only one of more than a thousand different odorant receptor genes.

Decoding the olfactory map through targeted transcriptomics links murine olfactory receptors to glomeruli

open access: yesNature Communications, 2022
Targeted spatial transcriptomics mapped olfactory receptor mRNAs to sections of the murine olfactory bulb to generate an interactive, statistical, 3D model of glomeruli locations and identify an ultra-sensitive receptor-odorant relationship.

A histological protocol for quantifying the birthrates of specific subtypes of olfactory sensory neurons in mice

open access: yesSTAR Protocols, 2023
Summary: Mammals typically have hundreds of distinct olfactory sensory neuron subtypes, each defined by expression of a specific odorant receptor gene, which undergo neurogenesis throughout life at rates that can depend on olfactory experience.

Neuroethology of olfactory-guided behavior and its potential application in the control of harmful insects [PDF]

open access: yes, 2016
Harmful insects include pests of crops and storage goods, and vectors of human and animal diseases. Throughout their history, humans have been fighting them using diverse methods.

Perception‐transduction‐transmission separation bionic H2S sensor

open access: yesInfoScience, EarlyView.
The modular separation of biological olfactory systems boasts unparalleled efficiency in olfactory recognition. Introducing this perception‐transduction‐transmission separation design into chemiresistive gas sensors (bionic olfactory sensing) based on the heterojunction rectification effect overcomes the inherent limitations of traditional sensor ...
