Determination of asparagine, glutamine and pyrrolidonecarboxylic acid in total enzymic hydrolysates of peptides and glycopeptides by gas–liquid chromatography [PDF]

open access: yesBiochemical Journal, 1973
A new procedure for the qualitative and quantitative determination of asparagine, glutamine and pyrrolidonecarboxylic acid in total enzymic hydrolysates of peptides and glycopeptides based on g.l.c. has been developed. Under the conditions of esterification and trifluoroacetylation N-trifluoroacetylaspartic acid mono-n-butyl ester was formed from ...

[Retracted] Hot Air Treatment Elicits Disease Resistance against Colletotrichum gloeosporioides and Improves the Quality of Papaya by Metabolomic Profiling

open access: yesBioMed Research International, Volume 2022, Issue 1, 2022., 2022
Forced air heat treatment could induce defenses to protect fruit from pathogen attacks and has been applied as an alternative to methyl bromide for phytosanitary treatment before exportation. However, few studies were reported on the regulation mechanism of antifungal effect and delayed physiological disorders of papaya by heat treatment. Therefore, we

Artemisinin Alleviates Intestinal Inflammation and Metabolic Disturbance in Ulcerative Colitis Rats Induced by DSS

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022
Objective. This study is aimed to reveal the possible mechanisms of artemisinin in the treatment of ulcerative colitis (UC) through bioinformatics analysis and experimental verification in UC model rats. Methods. Firstly, we searched two microarray data of the Gene Expression Omnibus (GEO) database to explore the differentially expressed genes (DEGs ...

Real‐Time Imaging of Ammonia Release from Single Live Cells via Liquid Crystal Droplets Immobilized on the Cell Membrane

open access: yesAdvanced Science, Volume 6, Issue 20, October 16, 2019., 2019
Ammonia (NH3) diffuses from the cell to the cellular microenvironment. With a dissociation constant (pKa) of 9.3, the NH3 + NH4+ content is 99% composed of NH4+ ions. The NH4+ ions interact with the COO−‐functionalized liquid‐crystals (LCs), which results in a radial‐to‐bipolar change of the LC droplet.

A Pilot Study on Characteristics of Metabolomics and Lipidomics according to Sasang Constitution

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2018, Issue 1, 2018., 2018
Although classification of an individual’s Sasang constitution is a key step in the prescription of traditional Korean medicine, the classifying process is complex and not objective. Identification of metabolic‐based biomarkers could allow the development of a reliable and sensitive classification technique and even therapeutic management.

LC‐MS‐Based Metabolic Fingerprinting of Aqueous Humor

open access: yesJournal of Analytical Methods in Chemistry, Volume 2017, Issue 1, 2017., 2017
Aqueous humor (AH) is a transparent fluid which fills the anterior and posterior chambers of the eye. It supplies nutrients and removes metabolic waste from avascular tissues in the eye. Proper homeostasis of AH is required to maintain adequate intraocular pressure as well as optical and refractive properties of the eye.
