Analysis of volatile compounds of sour guava (Psidium acidum [DC.] Landrum) using headspace-solid phase microextraction

Revista CENIC Ciencias Químicas, 2021
Application of headspace-solid phase microextraction combined with gas chromatography coupled to flame ionization, mass spectrometry and olfactometric detectors was used to analyze, for the first time, the volatile compounds of sour guava (Psidium acidum

Investigations on the Key Odorants Contributing to the Aroma of Children Soy Sauce by Molecular Sensory Science Approaches

Foods, 2021
To investigate the key odor-active compounds in children’s soy sauce (CSS), volatile components were extracted by means of solvent extraction coupled with solvent-assisted flavor evaporation (SE-SAFE) and solid-phase microextraction (SPME).

Combining indoor residual spraying and insecticide-treated nets for malaria control in Africa: a review of possible outcomes and an outline of suggestions for the future. [PDF]

, 2011
Insecticide-treated nets (ITNs) and indoor residual spraying (IRS) are currently the preferred methods of malaria vector control. In many cases, these methods are used together in the same households, especially to suppress transmission in holoendemic ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Characterization of odor components of Pixian Douban (broad bean paste) by aroma extract dilute analysis and odor activity values

International Journal of Food Properties, 2019
The odor-active compounds of Pixian Douban (PXDB) were identified by means of gas chromatography-olfactometry (GC-O) coupled with mass spectrometry (MS), and then the key odor components were figured out by odor activity values (OAVs) and aroma extract ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Odor-active Compound Adsorption onto Bentonite in a Model White Wine Solution

Chemical Engineering Transactions, 2013
The mechanisms and occurrence of aroma depletion during wine fining is still not clear. Previous results of our group led to hypothesized that some odor-active compounds were removed through direct adsorption mechanism on the clays without the ...

Flavor Nucleotides and Volatile Flavor Compounds of Net-Cage Farmed Triploid Rainbow Trout in Qinghai Province

Shipin gongye ke-ji, 2022
To investigate the flavor profile of triploid rainbow trout from Qinghai Province, high performance liquid chromatography (HPLC) and headspace solid phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS) were used to ...

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...
