What's the difference between dag and poniard?

Dag


Definition:

  • (n.) A dagger; a poniard.
  • (n.) A large pistol formerly used.
  • (n.) The unbranched antler of a young deer.
  • (n.) A misty shower; dew.
  • (n.) A loose end; a dangling shred.
  • (v. t.) To daggle or bemire.
  • (v. t.) To cut into jags or points; to slash; as, to dag a garment.
  • (v. i.) To be misty; to drizzle.

Example Sentences:

  • (1) In general, optimal DAGAT activity in vitro was observed when long-chain unsaturated acyl-CoAs and diacylglycerols (DAGs) containing long acyl chains were used as substrates for in vitro TAG synthesis (although 1,2-didecanoin was also very effective).
  • (2) Incubation of microsomes with CDP-DAG of different fatty acid composition results in quantitative and qualitative differences in lysoPI formation.
  • (3) We now report that two synthetic diacylglycerols (DAG) replicate the stimulatory and inhibitory effects of TPA on frog skin.
  • (4) The distribution of PKC returned to control values by 24 h. High glucose did not stimulate phosphoinositide hydrolysis, as evidenced by the absence of an increase in the water-soluble inositol phosphates, indicating that DAG was not generated through the action of a phosphoinositide-specific phospholipase C. Cells treated with the cell-permeable DAG analogue 1-oleoyl-2-acetyl glycerol to activate PKC displayed approximately two-fold increases of fibronectin, laminin, and type IV collagen mRNA levels after normalization against actin.
  • (5) We observed a 30-45% increase in DAG in rat gastrocnemius and diaphragm muscles, 5-15 min after intramuscular or intravenous injections of 1-3 U of insulin per rat, doses which would be expected to activate insulin receptors more fully.
  • (6) Concomitantly, an increase of inositol phosphates and diacylglycerol (DAG) production was observed.
  • (7) The accumulation of [14C]C20:4-DAG (lower in ET than in saline-infused rats) was paralleled by a decrease in phosphatidylinositol (PI) labelling, whereas phosphatidic acid showed a transient increase by 5 min in saline- but not in ET-infused rats.
  • (8) To determine the role of the DAG produced upon bombesin stimulation, we examined the effects of another activator of protein kinase C, the phorbol ester 12-O-tetradecanoylphorbol 13-acetate (TPA).
  • (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.
  • (11) The E. coli dgkA locus which contains the coding sequences for DAG kinase was subcloned into an eukaryotic expression vector, pMT2.
  • (12) The mean residence time for pharmacologically active molecules in the body was six times shorter for DAG (1.9 hr) than for DBD (11.4 hr).
  • (13) These data suggest that PKC is a mediator in the generation of DAG.
  • (14) These results suggest that DAG accumulation is involved in the potentiating effect of A23187 on CCh-stimulated amylase secretion.
  • (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.

Poniard


Definition:

  • (n.) A kind of dagger, -- usually a slender one with a triangular or square blade.
  • (v. t.) To pierce with a poniard; to stab.
