Fragrances in Remote Areas

Far from the general idea of pristine environments, remote areas may be affected by emissions from local human settlements and by the long-range transport of pollutants. Fragrances, as widely used components in household and personal care products (PCPs),

Change and persistence of fragrances given by washing [PDF]

When clothes have been washed, they retain various fragrances. Recently, addition of fragrances to the softeners has been commercialized. Also, fragrance additive agents are being sold separately to meet the consumers’ tastes. In the present study, these

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

FEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Fibroblast-derived matrix human skin equivalents reveal distinct roles for papillary and reticular fibroblasts in human skin barrier integrity and aging

Scientific Reports
The lipidic skin barrier can be compromised by skin aging, driven by internal and external factors. With age the reticular dermal layer increases, suggesting that changes in the dermal phenotype influences skin barrier integrity with age.

Daily supplementation with canine-isolated Limosilactobacillus reuteri ATCC PTA 6127 is well tolerated, improves stool consistency, and modulates gut microbiome in dogs

Frontiers in Veterinary Science
Probiotics are increasingly incorporated into companion animal diets to support gastrointestinal function, yet strain-specific evidence in dogs remains limited.

The Blossoming of Technology for the Analysis of Complex Aroma Bouquets—A Review on Flavour and Odorant Multidimensional and Comprehensive Gas Chromatography Applications

Molecules, 2019
Multidimensional approaches in gas chromatography have been established as potent tools to (almost) attain fully resolved analyses. Flavours and odours are important application fields for these techniques since they include complex matrices, and are of ...

Quantification of coumarins, furocoumarins and polymethoxyflavones in hydroalcoholic fragrances by supercritical fluid chromatography‐tandem mass spectrometry

, 2023
Citrus essential oils, thanks to their pleasant aroma, are certainly the most used ingredients in the formulation of hydroalcoholic fragrances. The non-volatile fraction of Citrus essential oil is composed for 10–20% of coumarins, furocoumarins and ...

Heterotropic regulation and negative homotropic cooperativity

FEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Masculinity/Femininity of Fine Fragrances Affects Color-Odor Correspondences: A Case for Cognitions Influencing Cross-Modal Correspondences

, 2008
Four experiments found that the colors people choose as corresponding to the odors of fine fragrances are influenced by the perceived masculinity/ femininity of those fragrances. Experiment 1 examined the colors chosen for 3 male and 3 female fragrances.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...
