Phytoecdysteroids from the Roots of Achyranthes bidentata Blume

Molecules, 2012
Two new phytoecdysteroids, (25S)-20,22-O-(R-ethylidene)inokosterone (1) and 20,22-O-(R-3-methoxycarbonyl)propylidene-20-hydroxyecdysone (2), together with six known phytoecdysteroids 3–8 were isolated from the roots of Achyranthes bidentata Blume.

Putative role of corazonin in the ovarian development of the swimming crab Portunus trituberculatus

Frontiers in Marine Science, 2022
Corazonin (Crz) is a neuropeptide that widely distributed in insects and crustaceans. The Crz is proposed to have pleiotropic functions in insects, but its physiological roles in crustaceans are poorly understood.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

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

Journal of Clinical Periodontology, EarlyView.
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.

Synthesis and Structure-Activity Relationships of Novel Ecdysteroid Dioxolanes as MDR Modulators in Cancer

Molecules, 2013
Ecdysteroids, molting hormones of insects, can exert several mild, non-hormonal bioactivities in mammals, including humans. In a previous study, we have found a significant effect of certain derivatives on the ABCB1 transporter mediated multi-drug ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

Biological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

Food Frontiers, Volume 7, Issue 2, March 2026.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.

Resource Availability Modulates Gene Expression Across Life Stages in a Migratory Butterfly

Molecular Ecology, Volume 35, Issue 5, March 2026.
ABSTRACT Natural populations are in constant need of balancing resource allocation to compensate for seasonal environmental variation. In many insects, a well‐established trade‐off between migration and reproduction exists. While this trade‐off has been characterised phenotypically for decades, the underlying regulatory pathways are poorly understood ...

Molecular and Endocrine Regulation of Ovarian Maturation in the Black Tiger Prawn (Penaeus monodon) and Associated Challenges in Its Aquaculture

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Over the past four decades, substantial research has investigated the regulation of ovarian maturation and spawning in the black tiger prawn (Penaeus monodon). In this species, female reproduction is strongly suppressed by gonad‐inhibiting hormone (GIH) released from the eyestalk, making eyestalk ablation (ESA) the most widely adopted spawning‐

Bed bug preferences for host odor or aggregation odor are differentially modulated by physiological state in various odorscapes

Pest Management Science, Volume 82, Issue 2, Page 1426-1436, February 2026.
The bed bug olfactory system is highly tuned to two odor sources with dedicated odor information‐processing pathways that are modulated by the satiety–hunger state. Understanding the dynamic nature of switching odor preferences at different phases of blood digestion will contribute to the development of lures with host kairomones and aggregation ...
