Dag


Definition:

Example Sentences:

  • (9) It is concluded that carbachol increases [Ca2+]i by facilitating Ca2+ entry through L-type Ca2+ channels via a 1,2-diacylglycerol (DAG)-protein kinase C (PKC)-dependent pathway while quisqualate mobilizes Ca2+ from inositol 1,4,5-trisphosphate (IP3)-sensitive stores.
  • (10) In order to characterize the properties of the glyceroglycolipid membranes, ESR spectroscopic studies were carried out with an acyl spin-labeled galactosyl ceramide (SL-GC) or a headgroup spin-labeled phospholipid (SL-6-DPPA) in 1,2-dipalmitoyl[beta-cellobiosyl-(1'---3)]glycerol (Cel-DAG) liposomal membranes.

  • (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.

  • (17) Rather than pointing fingers or assigning blame, let’s use this occasion to expand our moral imaginations, to listen to each other more carefully, to sharpen our instincts for empathy and remind ourselves of all the ways that our hopes and dreams are bound together … If this tragedy prompts reflection and debate – as it should – let’s make sure it’s worthy of those we have lost.
