Combinatorial Receptor Codes for Odors [PDF]

Cell, 1999
The discriminatory capacity of the mammalian olfactory system is such that thousands of volatile chemicals are perceived as having distinct odors. Here we used a combination of calcium imaging and single-cell RT-PCR to identify odorant receptors (ORs) for odorants with related structures but varied odors.

Starch‐Molded Snacks Enriched With Nance (Byrsonima crassifolia L.) Fruit Flour Functional Potential

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Nance flour enriches starch‐molded snacks with antioxidants and fiber. These innovative snacks offer high phenolic bioaccessibility and improved sensory appeal, valorizing an underutilized fruit for sustainable food development. ABSTRACT This study aimed to develop starch‐molded snacks enriched with nance (Byrsonima crassifolia L.) flour, a native ...

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.

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 ...

An odorant receptor for a key odor constituent of ambergris

Communications Biology
Ambergris, a substance derived from the digestive system of sperm whales, has been valued for centuries for its unique aromatic properties. However, historical accounts indicate that certain human populations, particularly in East Asia, utilized ambergris without regard for its odor quality.

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.

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 ...

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Sufficient Gas and Solvated Ion Transport Assisted Rapid NH3 Detection at Room Temperature Through Bionic Olfactory Fibres

Exploration, EarlyView.
Bionic olfactory fibres with nanoconfined ionic liquids were developed to mimic human olfactory cilia. Benefiting from sufficient gas transport pathways provided by inter‐fibre interconnected pores and rapid transport of solvated ions in the confined nano spacing, bionic olfactory fibres show excellent sensing performance to NH3 and demonstrate the ...
