(15) It is concluded that insulin-dependent PDH activation, PIG hydrolysis, and IG and DAG generation are mediated by the wild-type but not by the mutated insulin receptor of Val996.
(16) Since most alloantibodies detected only by 2SP-IAT or LISS-DAG were of doubtful clinical significance, and these techniques produced a high number of unwanted positive reactivities, we conclude that 2SP-IAT and LISS-DAG are not appropriate for the pretransfusion screening for unexpected antibodies.
(17) 261, 8597-8600), lipase from Rhizopus arrhizus selectively degraded the 1-acyl-containing species (DAG), but the ether lipid (EAG) was resistant and was identified and quantified after thin layer chromatography separation.
(18) 1-Oleoyl-2-acetylglycerol, a synthetic DAG analog, stimulated endothelial cell DNA synthesis in a concentration-dependent manner.
(19) Whereas DPG and DS are stable at physiological pH, DAG is unstable, undergoing hydrolysis (regeneration of DF) and rearrangement (intramolecular acyl migration to the 2-, 3- and 4-O-acyl-positional isomers).
(20) Addition of PRL to hepatocyte cultures significantly increased [3H]-glycerol incorporation into DAG within 5 minutes which was followed by a loss of cytosolic PKC activity by 10 minutes.
Dago
Definition:
(n.) A nickname given to a person of Spanish (or, by extension, Portuguese or Italian) descent.
Example Sentences:
(1) Unlike thiorphan, 5 nmol RB38A alone was able to inhibit [3H]DAGO binding by 60%.
(2) SKF 38393 (1 microM)-stimulated adenylate cyclase activity was strongly reduced (by almost 60%) by the highly selective mu-agonist [D-Ala2, MePhe4, Gly-ol5]-enkephalin (DAGO; EC50 = 0.006 microM) and high concentrations of the selective delta-agonist [D-Ser2(O-tert-butyl), Leu5]-enkephalyl-Thr6 (DSTBU-LET; EC50 = 0.13 microM) but not by the selective delta-agonist [D-penicillamine2, D-penicillamine5]enkephalin (DPDPE).

(6) MOR, DAGO and NALO produced mixed effects (i.e., excitation or inhibition) on unit activity; however, the majority of cells examined (67%) were inhibited.
(7) This effect of DAGO was not due to spread to the third ventricle and subsequent diffusion via the CSF to another CNS site, since push-pull perfusion with this dose of DAGO in the region just dorsal to or in the posterior hypothalamus was ineffective in altering LH pulse amplitude.
(8) The mu-agonist DAGO ([D-Ala2,N-MePhe4,Gly-ol5]enkephalin; 0.75 nmol i.c.v.)
(9) Mu and delta receptors were labeled with the selective ligands 3H-DAGO (Tyr- D-Ala-Gly-MePhe-Gly-ol), and 3H-DPDPE (D-Pen2, D-Pen5-enkephalin), respectively, while the kappa receptors were labeled with 3H-(-)bremazocine in the presence of unlabeled DAGO and DPDPE.

(11) The purpose of the present study was firstly to determine whether morphine and (D-Ala2, NMe-Phe4, Gly-ol)-enkephalin (DAGO), a highly selective mu-agonist, increased intracellular free calcium of rat myocytes and secondly to determine whether opioid receptors were involved.

(16) Receptor autoradiographic studies with 3H-DAGO were carried out in the central gray to find receptor populations differing greatly in density between HAR and LAR mice to parallel their in vivo sensitivity differences: such receptors would then be implicated in mediating in vivo analgesia.
(17) Eighty percent of [3H]-[D-Ala2,D-Leu5] enkephalin (DADLE) binding was displaced by DAGO with high affinity, indicating that a high percentage of [3H]-DADLE binding was at mu-sites.
(18) In untreated animals, morphine and the mu-selective peptide, DAGO, induced relatively long-lasting dose-related decreases in responding, whereas the non-mu agonists, DPDPE and dynorphin, induced only transient effects: response rates increased at low doses and decreased at high doses.
