A peptide inhibiting ecdysteroid biosynthesis in the PG was isolated from the extracts of 2,000 larval brains of the silkworm, Bombyx mori, using a protocol that included four reversed-phase high performance liquid chromatography procedures, which indicates that Bom-PTSP interferes with PTTH-stimulated ecdySTERoidogenesis.

This work has identified phosphoenolpyruvate and 3-phosphoglycerate, intermediates of the glycolytic pathway, in exoskeleton and gastroliths and found them important for stabilizing ACC.
Identification and characterization of two distinct GnRH receptor subtypes in a teleost, the medaka Oryzias latipes.
Phylogenetic analysis showed the presence of three paralogous lineages for vertebrate GnRH-Rs and indicated that neither Gn RH-R1 nor GnRh-R2 is the medaka ortholog to mammalian GnRH -Rs that lack a cytoplasmic tail, which suggests that a third Gnrh-R may exist in themedaka.

Three Bombyx mori orphan neuropeptide G protein-coupled receptors are identified as receptors for ITP and ITPL (collectively referred to as ITPs), demonstrating that BngR-A2 and -A34 are ITP receptors and that BNGR- a24 is an ITPL receptor in B. mori.

Results of analyses using membrane filtration, size-exclusion chromatography and electrospray ionisation time-of-flight mass spectrometry indicate that Cu in the xylem sap is dominantly complexed by 2'-deoxymugineic acid, whereasCu in the phloem sap is bound to several compounds, i.e. nicotianamine, histidine and other >3-kDa compounds.
The alpha subunit of tryptophan synthase. Evidence that aspartic acid 60 is a catalytic residue and that the double alteration of residues 175 and 211 in a second-site revertant restores the proper…

It is concluded that the restoration of alpha subunit activity in the doubly altered second-site revertant results from restoration of the proper geometry of the substrate binding site.
