Ecdysteroid regulation of gene transcription in Drosophila melanogaster and other insects is mediated by a heterodimer comprised of Ultraspiracle (USP) and one of three ecdysone receptor (EcR) isoforms (A, B1 and B2). This study revealed that the EcR/USP heterodimer displays isoform-specific capabilities. EcRB1 is normally induced with a form of USP that is missing its DNA-binding domain (DBD),...

Plant cell wall synthesis requires a number of different nucleotide sugars which provide the building blocks of the different polymers. These nucleotide sugars are mainly provided by de novo synthesis but recycling pathways also contribute to the pools. The last enzyme of the recycling pathway is UDP-sugar pyrophosphorylase (USP), a single copy gene in Arabidopsis, of which a knockout is lethal...

Acetaminophen is one of the most important antipyretic and analgesic drugs. It has an excellent efficacy when it's used in therapeutic doses, but in unsafe doses it can be resulted in hepatotoxicity and permanent liver failure. Due to disparities that have been reported between the actual and stated concentration of acetaminophen tablets, we aimed to compare the actual quantity of 8 Iranian gen...

Fentanyl Citrate Injection, USP is a potent o p i o i d ag o nis t . Each milliliter of solution contains fentanyl citrate equivalent to 50 mcg of fentanyl base, adjusted to pH 4.0 to 7.5 with sodium hydroxide. Fentanyl citrate is chemically identified as N-(1-phenethyl-4-piperidyl) propionanilide citrate (1:1) with a molecular weight of 528.60. The empirical formula is C22H28N2O • CH8O7. The s...

CLINICAL PHARMACOLOGY Methylergonovine maleate acts directly on the smooth muscle of the uterus and increases the tone, rate, and amplitude of rhythmic contractions. Thus, it induces a rapid and sustained tetanic uterotonic effect which shortens the third stage of labor and reduces blood loss. The onset of action after I.V. administration is immediate; after I.M. administration, 2 to 5 minutes,...

Only physicians experienced in management of systemic immunosuppressive therapy for the indicated disease should prescribe Cyclosporine Capsules USP (Modified). At doses used in solid organ transplantation, only physicians experienced in immunosuppressive therapy and management of organ transplant recipients should prescribe Cyclosporine Capsules USP (Modified). Patients receiving the drug shou...

Ecdysteroids (Ecs) enhance the formation of Ec receptor-ultraspiracle protein (EcR-USP) heterodimers which regulate gene transcription. To study EcR-USP heterodimerization, fusion proteins were constructed from the LBDs (ligand-binding domains) of Drosophila EcR or USP and the activation or DNA-binding region of GAL4 respectively. Reporter gene ( lacZ ) activation was fully dependent on the co-...

This analysis considers the structural evidence of a ligand-binding function of the nuclear receptor ultraspiracle (USP). The positions and nature of residues in the ligand-binding domain of USP from six higher insects is evaluated in comparison to the function of conserved residues vertebrate receptors that have been co-crystallized with ligand. USP appears to conserve residues that in vertebr...
