LEPHART, E. D. Age-related changes in brain and pituitary 5c~-reductase with finasteride (Proscar) treatment. NEUROBIOL AGING 16(4) 647-650, 1995.-Finasteride (Proscar), a 5u-reductase inhibitor, was administered with or without 5u-dihydrotestosterone (DHT) in juvenile (28), peripubertal (48), or young adult (68-day-old) male rats. Luteinizing hormone (LH) levels and ventral prostate (VP) weigh...
The activity of juvenile hormone esterase (JHE) in feeding fifth instar larvae of Manduca sexta increases gradually with larval weight and rises to a peak after larvae pass the critical weight when juvenile hormone secretion ceases. Starvation of larvae of Manduca sexta (L.) that had exceeded the critical weight inhibited peak levels of JHE, but did not delay entry into the wandering stage when...
BACKGROUND The impact of Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) infection on host gene expression in Spodoptera exigua 4th instar larvae was investigated through the use of 454 sequencing-based RNA-seq of cDNA libraries developed from insects challenged with active AcMNPV or heat-inactivated AcMNPV. METHODOLOGY/PRINCIPAL FINDINGS By comparing the two cDNA libraries, ...
Metabolites of the 6,7,10,11 bisepoxide juvenile hormone III (JHB(3)), and other potential juvenoids, were tested for juvenile hormone activity using early instar or early stage pupae of Drosophila melanogaster. Importantly, methyl farnesoates were tested as they might have JH-like activity on Dipteran juveniles. Larvae were exposed to compounds in medium, or the compounds were applied to white...
Juvenile hormone titers and reproductive characteristics were measured in adult wing and flight-muscle morphs of the wing-polymorphic cricket, Gryllus firmus, during the first week of adulthood. This species has three morphs: one flight capable morph with fully-developed wings and fully-developed flight muscles [LW(F)], one flightless morph with fully-developed wings and histolyzed (non-functio...
In this study diflubenzuron as a chitin synthesis inhibitor with a dosage of 25 mg A.I/L, and Pyriproxyfen as a juvenile hormone analogue with a dosage of 0.4 mgA.I/L were incorporated in the wax diets of young and last instar larvae of greater wax moth and reared at different temperatures (25, 30, 35°C). Results showed that these compounds in comparison with control increased larval mortality....

Insect Haemolymph, Hormone Binding Proteins, Juvenile Hormone, Photoaffinity Labelling, Manduca sexta, Locusta migratoria Juvenile hormone III, i.e. methyl 10,1 l-epoxy-3,7-dimethyl-2£’,6£'-dodecadienoate, was used for photoaffinity labelling of JH-binding proteins. Irradiation of haemolymph from Manduca sexta and Locusta migratoria in the presence of racemic [10-3H]JH-III results in covalent i...
