Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Odorant receptors of Drosophila are sensitive to the molecular volume of odorants [PDF]

Scientific Reports, 2016
Abstract Which properties of a molecule define its odor? This is a basic yet unanswered question regarding the olfactory system. The olfactory system of Drosophila has a repertoire of approximately 60 odorant receptors.

Determining the Minimal Clinically Important Difference of the 40‐Item Smell Identification Test in People With Cystic Fibrosis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) and olfactory dysfunction (OD) are highly prevalent among people with cystic fibrosis (PwCF) and negatively impact quality of life. The 40‐item Smell Identification Test (SIT) is widely used to assess psychophysical olfaction, but a CF‐specific minimal clinically important difference (MCID) has not been ...

Lost and Found: Is Olfactory Recovery More Promising After COVID‐19 Than Other Causes, Even 2 Years Later?

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction is a hallmark feature of COVID‐19, yet the potential for recovery with long‐standing COVID‐19‐related smell loss (CRSL) remains uncertain, particularly when treatment is initiated years later. This study evaluated olfactory outcomes in patients with CRSL compared with non‐COVID‐19‐related smell loss (non‐CRSL),

Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

Advanced Physics Research, EarlyView.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

Can trigeminal sensations impact saltiness perception? A mini‐review

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Many food companies have begun to reduce the salt content in their products due to health concerns; however, this reduction in salt content can affect the food's sensory appeal and flavour complexity. Flavour is defined as a combination of odour (i.e., smell), taste (i.e., gustation) and trigeminal sensations (i.e., chemesthesis).

Unique Features of Nasal Airway and Airflow Improvement Post‐Dupilumab: A Computational Cohort Study

The Laryngoscope, EarlyView.
The impact of dupilumab on nasal airway patency and airflow is not uniform. It is more pronounced in the middle and superior, but not inferior meatus. These unique regional changes significantly correlate with and potentially drive the improvement in patient symptoms.

Exocrine Gland Dysfunction in Parkinson's Disease: Pathophysiology, Clinical Manifestations, and Therapeutic Perspectives—A Narrative Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Non‐motor symptoms, especially autonomic dysfunction, are major contributors to disability and decreased quality of life in Parkinson's disease (PD). Despite being common and having a wide range of clinical facets, exocrine gland dysfunction is still not well recognized and managed.

Commercial permethrin elicits chemoreceptive responses on different Anopheles gambiae sensory appendages

Pest Management Science, EarlyView.
Anopheles gambiae mosquitoes exhibit takeoff responses when presented to commercial permethrin headspace. This product elicits electrophysiological activity in the antennae and tarsi. However, only the chemical information acquired from the tarsi plays a major role in the observed behavioral response.

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

STAR 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.
