Natural and Synthetic Materials with Insect Hormone Activity. 5. Specific Juvenile Hormone Effects in Aliphatic Sesquiterpenes.

Natural and synthetic materials with insect hormone activity. IV. Specific female sterility effects produced by a juvenile hormone analogue.

The effects of short-term growth hormone (somatotropin) bath on some growth and immunity indices in the early stages of growth in rainbow trout (Oncorhynchus mykiss)

This study was conducted to determine the effect of growth hormone on some growth and immunity parameters at three stages of rainbow trout eyed egg, alvin and fry. The experiment was carried out in 4 treatments with concentrations of 0, 0.1, 0.5 and 1 mg/l of somatotropin hormone. For permeability, different experimental groups were treated with sodium hypochlorite (0.005 %) for 15 seconds befo...

Aspergillus nidulans Synthesize Insect Juvenile Hormones upon Expression of a Heterologous Regulatory Protein and in Response to Grazing by Drosophila melanogaster Larvae

Secondary metabolites are known to serve a wide range of specialized functions including communication, developmental control and defense. Genome sequencing of several fungal model species revealed that the majority of predicted secondary metabolite related genes are silent in laboratory strains, indicating that fungal secondary metabolites remain an underexplored resource of bioactive molecule...

Hypermetabolic Response Induced by Juvenile Hormone Analogues in an Insect

Some synthetic analogues o f insect juvenile hormone cause tremendous rise o f respiratory m e­ tabolism in the last larval instar o f Dermestes maculatus. The 0 2 consumption values occasionally found in these hypermetabolic larvae (20 m l/g /h ) can be classified among the most intensive res­ piratory rates ever recorded in living organisms. The phenomenon is directly related to the dose o f ...

Growth Promotion in Pea Stem Sections. III. By Alkyl Nitriles, Alkyl Acetylenes and Insect Juvenile Hormones.

C(14), C(15), and C(16) alkyl nitriles, and C(16) and C(18) alkyl acetylenes at 10 to 105 micromolar concentrations promote the growth of stem sections from red-light-exposed seedlings of dwarf peas (Pisum sativum L. cv. Progress No. 9). Similar results were obtained with substances active as insect juvenile hormones, namely farnesol, the racemic ethyl ester of 1 of the natural hormones, and a ...
