Juvenile fibromatosis: hormonal receptors
International Journal of Pediatric Otorhinolaryngology, 1993Aggressive juvenile fibromatosis, though allegedly a benign process, is as frustrating to manage as it is perplexing to comprehend. The treatment is primarily surgical, with chemotherapy and radiation therapy recently finding support as adjuncts in selected circumstances.

Juvenile hormone esterase is a biochemical anti-juvenile hormone agent
Insect Biochemistry, 1990Juvenile hormone esterase, purified by affinity chromatography from the larval hemolymph of Manduca sexta in the fifth stadium, was injected into larvae of the same species in the earlier stadia resulting in a blackening of the cuticle following ecdysis to the next larval stadium.

The morphostatic actions of juvenile hormone
Insect Biochemistry and Molecular Biology, 2007The maintenance of "status quo" in larvae by juvenile hormone (JH) involves both the programming of ecdysteroid-dependent synthesis during the molt and the suppression of morphogenetic growth during the intermolt. The latter morphostatic action does not require ecdysteroids, and has been studied in the formation of imaginal discs in Manduca sexta ...

Regulation of the Juvenile Hormone Titer
Annual Review of Entomology, 1981Juvenile hormone (JH) is produced by the corpora allata (CA) of insects. It regulates development and reproduction and also plays a crucial role in polymorphism. These functions have been amply reviewed (13, 21, 23, 29, 30, 112, 141). However, little information is available on the mechanisms of these effects, mainly because of the difficulty in ...

Peptides with Juvenile Hormone Activity
Science, 1970Peptide derivatives of juvenile hormone analogs which show substantial hormonal activity for certain insects were prepared. The most active compound, L-isoleucyl-L-alanyl- p -aminobenzoic acid ethyl ester, was up to twice as active as juvabione.

The Juvenile Hormone Receptor and Molecular Mechanisms of Juvenile Hormone Action
2014Abstract Juvenile hormone (JH) is a critical regulator of insect development and physiology, widely known for its ability to delay metamorphosis. The mechanisms underlying the action of JH have been poorly understood, partly as a result of difficulties identifying the JH receptor.

Activity of juvenile hormone and juvenile hormone analogues on the growth of Trypanosoma cruzi
The Journal of Steroid Biochemistry and Molecular Biology, 1996The effects of juvenile hormone-III (JH-III) and the juvenile hormone analogues (JHA) methoprene and fenoxycarb on the growth and macromolecular biosynthesis in Trypanosoma cruzi were studied in vitro. It was observed that JH-III and JHA blocked growth and 3H-thymidine incorporation without killing the cells within certain concentrations (< or = 1 x 10(

Journal of Insect Physiology, 1973
Abstract The morphogenetic effects of t,t -farnesol, Law-Williams juvenile hormone analogue, dichlorofarnesenic acid ethyl ester (DFAEE), and a syntetic racemic or isomeric mixture of C 18 juvenile hormone (JH), when applied topically to pharate pupae and adults of D. melanogaster have been studied.
