Untargeted Metabolomic and Lipidomic Profiles of Gingival Crevicular Fluid in the Context of Periodontitis

open access: yesJournal of Clinical Periodontology, Volume 53, Issue 5, Page 774-783, May 2026.
ABSTRACT Aim(s) This cross‐sectional clinical study aimed to explore the untargeted metabolomic and lipidomic profiles in gingival crevicular fluid (GCF) obtained from healthy individuals and patients with periodontitis. Materials and Methods GCF was collected from 17 periodontally healthy and 19 periodontitis patients.

The role of 20-hydroxyecdysone in the CNS metamorphosis in flesh fly (Neobellieria bullata) larvae (Diptera: Sarcophagidae)

open access: yesEuropean Journal of Entomology, 2005
The role of 20-hydroxyecdysone (20E) in the metamorphosis of the central nervous system was investigated by recording feeding, wandering and pupariation behaviour as the measures of hormonal effects on the neural tissues in the flesh fly Neobellieria ...

Characterization of the Molt Stages in Penaeus vannamei: Setogenesis and Hemolymph Levels of Total Protein, Ecdysteroids, and Glucose

open access: yes, 1988
The molting cycle of Penaeus vannamei ju veniles was characterized by distinct and predictable changes in the setae of pleopods. The molt pattern was diecdysic with a relatively short intermolt period (40%) and a long proecdysial period (>53%).

Ecdysteroid Profiles of Two species, and

open access: yesNatural Product Communications, 2014
Phytoecdysteroids are plant analogues of insect moulting hormones and are used by plants to repel or disturb phytophagous insects. They are also active on mammals and present in many plants used in traditional medicine.

Phytoecdysteroids in the Genus (Polypodiaceae) of French Polynesia

open access: yesNatural Product Communications, 2007
A chemical survey of the six species of Microsorum in French Polynesia has been performed to determine and quantify the phytoecdysteroids. The content and composition of these compounds in the fronds of each of the six species were established.

Vitamin D1 versus ecdysteroids: Growth effects on cell regeneration and malignant growth in insects are similar to those in humans

open access: yesEuropean Journal of Entomology, 2019
Polyhydroxylated derivatives of 6-keto,7-dehydrocholesterol (ecdysteroids) are common constituents of various plants. In 1965, they were accidentally discovered in the search for the insect moulting hormone. These biologically important natural compounds

Practical uses for ecdysteroids in mammals including humans: and update

open access: yes, 2003
Ecdysteroids are widely used as inducers for gene-switch systems based on insect ecdysteroid receptors and genes of interest placed under the control of ecdysteroid-response elements. We review here these systems, which are currently mainly used in vitro

Isolation and Purification of Three Ecdysteroids from the Stems of Diploclisia glaucescens by High-Speed Countercurrent Chromatography and Their Anti-Inflammatory Activities In Vitro

open access: yesMolecules, 2017
High-speed counter-current chromatography was used to separate and purify ecdysteroids for the first time from the stems of Diploclisia glaucescens using a two-phase solvent system composed of ethyl acetate–n-butanol–ethanol–water (3:0.2:0.8:3, v/v ...

Ecdysteroid-dependent molting in tardigrades

open access: yesCurrent Biology
Abstract Molting is a defining feature of the most species-rich animal taxa, the Ecdysozoa, including arthropods, tardigrades, nematodes, and others. In pancrustaceans, such as insects and decapods, molting is regulated by the ecdysteroid (Ecd) hormone and its downstream cascade.
