Asynchronous Onset of Odorant Receptor Expression in the Developing Zebrafish Olfactory System

, 1996
The functional identity of an olfactory neuron is determined in large part by the odorant receptors it expresses. As an approach toward understanding the events that underlie the specification of olfactory neurons, we have examined the patterns of ...

Evaluating Anesthetics for Improving Scientific Research and Welfare Using Larval Zebrafish

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
Using physiological and behavioral assays, we quantified the effectiveness and appropriateness of six commonly used fish anesthetics on zebrafish embryos. Different anesthetics performed better under different contexts. Figure prepared using BioRender.com.

Wake Up and Smell the Infected Bees: Volatile Cues of Vairimorpha Infection in Honey Bees

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Infection can modify host volatile emissions, yet effects in adult honey bees remain unexplored. Using dynamic headspace sampling and GC × GC–MS, we show that Vairimorpha spp. infection significantly alters the volatile profile of adult worker honey bees over a 14‐day time series, producing stage‐specific shifts in multivariate odour structure.

Mechanism of odorant adaptation in the olfactory receptor cell

, 1997
Adaptation to odorants begins at the level of sensory receptor cells(1-5), presumably through modulation of their transduction machinery, The olfactory signal transduction involves the activation of the adenylyl cyclase/cyclic AMP second messenger system

Odor Modification in Rigid Polyethylene Waste: Impact of Different Washing on Sensory Analysis and Characterization

Global Challenges, Volume 10, Issue 6, June 2026.
Post‐consumer rigid polyethylene waste was characterized for odor‐active compounds using sensory analysis, comparative odor extract dilution analysis, and 2D‐GC‐MS/O. Twenty‐eight odorants were identified, with four reported for the first time. A direct comparison with polypropylene suggests polymer‐specific adsorption–desorption dynamics governed by ...

Odorant receptors make scents

, 2004
The goal of making sense of the sense of smell has come a step closer. Work on fruitflies reveals that odorant receptors act as bidirectional chemical detectors and determine the function of sensory neurons.

Gas Chromatography‐Based Methods for Profiling Volatile Off‐Aroma Compounds in Grain Legumes: A Review

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Instrumental characterisation of the volatile organic compounds (VOCs), responsible for off‐aroma, is mainly centred on gas chromatography‐based techniques. Despite previous reviews that have addressed the chemical compounds and biosynthetic pathways of off‐aroma generation, to date, there is a lack of a comprehensive review that critically ...

Identification of a receptor for the sex pheromone of the vine mealybug, Planococcus ficus

Current Research in Insect Science
The vine mealybug, Planococcus ficus, is a significant pest of vineyards in all major grape growing regions of the world. This pest causes significant aesthetic damage to berry clusters through its feeding behavior and secretion of ''honeydew'', which ...

Changes in the Epidemiology of Pediatric Olfactory Dysfunction Before and After COVID‐19 Pandemic

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 3, June 2026.
ABSTRACT Background The COVID‐19 pandemic may have altered the epidemiology and clinical features of pediatric olfactory dysfunction, but data focusing on children remain limited, particularly regarding etiological changes and qualitative symptoms such as parosmia.
