Applying a new version of the Brazilian-Portuguese UPSIT smell test in Brazil [PDF]

open access: yes, 2010
Standardized olfactory tests are now available to quantitatively assess disorders of olfaction. A Brazilian-Portuguese version of the University of Pennsylvania Smell Identification Test (UPSIT) is currently being developed specifically for the Brazilian

Cephalopod Olfaction

open access: yes, 2017
Within the Phylum Mollusca, cephalopods encompass a small and complex group of exclusively marine animals that live in all the oceans of the world with the exception of the Black and Caspian seas. They are distributed from shallow waters down into the deep sea, occupying a wide range of ecological niches. They are dominant predators and themselves prey

Insights Into Retronasal Sensation of Sweeteners Within Aerosol Particles Via Scalp Electroencephalogram

open access: yesSensory Neuroscience, EarlyView.
Sweeteners in aerosol form trigger retro‐nasal sensations that modulate early (P1) and late (P3) brain responses. EEG recordings reveal that sucrose and rebaudioside A elicit distinct ERP components only when retro‐nasal airflow is permitted, supporting aerosol‐based taste–smell integration and suggesting involvement of both top‐down and bottom‐up ...

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 ...

One‐Step Laser‐Induced Oxidation and Doping for Tailored p‐Type Conversion of Al‐Doped TiO₂

open access: yesSmall, EarlyView.
LODI achieves single‐step dynamic doping of Al‐doped TiO₂, allowing precise control of conductivity type and enhanced photostability. This method converts n‐type to p‐type TiO₂ in one step, eliminating thermal damage and offering scalability. Al‐doped TiO₂ enables advanced applications in CMOS and advanced electronic devices.

The manipulation of odor availability of training aids used in detection canine training

open access: yesFrontiers in Allergy
Detection canines can identify numerous substances for which they have been trained. Historically, and a point of ongoing contention, detection canine threshold (i.e., sensitivity or limit of detection) training has primarily focused on changing the ...

Ultrafast Photothermal‐Shock‐Driven Multimetallic Exsolution for Artificial Olfaction of Sulfur Compounds Detection

open access: yesSmall Structures, EarlyView.
This study utilizes the intense pulsed light process to rapidly form alloy nanocatalysts on the surface of porous ZnO, which are then applied as artificial olfactory materials for detecting volatile sulfur compounds gases in sensor applications. Exsolution‐driven metal catalysts have emerged as promising candidates for artificial olfaction applications,

Better olfaction was associated with lower healthcare expenditure among physically independent Japanese community-dwelling older adults: the Yanai study

open access: yesFrontiers in Aging
ObjectiveWe aimed to determine whether olfaction is associated with healthcare expenditure among physically independent, community-dwelling older adults.MethodsThis cross-sectional study included 162 community-dwelling older adults (mean age 70.2 ± 5.4 ...
