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

Advanced 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]

PLoS 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).

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

International 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 ...

Appropriate Medical Therapy Primarily Modifies Type 2 and Severity Biomarkers in Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Appropriate medical therapy (AMT) is first‐line treatment for patients with chronic rhinosinusitis (CRS). We evaluated inflammatory structure, treatment‐induced changes, and biomarker‐outcome associations in AMT‐managed patients. Methods Fifty‐one CRS patients were evaluated before and after AMT which included a combination of oral ...

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.

Identification of Genes Involved in Chemoreception in Plutella xyllostella by Antennal Transcriptome Analysis

Scientific Reports, 2017
Perception of environmental and habitat cues is of significance for insect survival and reproduction. Odor detection in insects is mediated by a number of proteins in antennae such as odorant receptors (ORs), ionotropic receptors (IRs), odorant binding ...

Expanding the olfactory code by in silico decoding of odor-receptor chemical space

eLife, 2013
Coding of information in the peripheral olfactory system depends on two fundamental factors: interaction of individual odors with subsets of the odorant receptor repertoire and mode of signaling that an individual receptor-odor interaction elicits ...

Comparative Effects of Three Microbial Starter Cultures on the Physicochemical and Sensory Quality of Fermented Sausages

Food Bioengineering, EarlyView.
ABSTRACT This study innovatively links specific microbial compositions of commercial starter cultures to the evolution of key odorant and taste‐active amino acids, revealing the underlying mechanisms behind distinct flavor profiles. Three microbial starter cultures—Saccharomyces cerevisiae (SC), Scarlet (ST), and Roxaane LC (LC), were added to sausages,

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

Flavour 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.
