(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.

Example Sentences:
(1) At the moment we are, if anything, slightly lagging."
(2) Initiation of the alternative pathway by the cryptococcal capsule is characterized by a lag in C3 accumulation and the appearance of a limited number of focal initiation sites which resemble those observed when the alternative pathway is activated by zymosan and nonencapsulated cryptococci.
(3) When cultures were pulse labeled for 15 min and then incubated under chase conditions for 105 min, the amount of degraded collagen attained a value equal to approximately 20% of the amount synthesized during the labeling period; the data were fit with a simple exponential function that had a 40-min rise time and a 12-min lag time.
(4) It is conceivable that DNA replication of RSF1010 does not need the priming mechanism for lagging strand synthesis and proceeds by the strand displacement mechanism.
(5) Supplementation of neuraminidase-treated Lp(a) with N-acetylneuraminic acid (NANA) at concentrations comparable to the naturally occurring amounts of NANA in the Lp(a) protein moiety led to an increase of the lag-phase yielding values which were comparable to those observed with native Lp(a).
(6) A more specific differentiation, as indicated by the sharp increase in GAD levels which was concurrent with an increase in interneuronal contacts, lagged behind the initial growth.
(7) It appears that the decline in plasma IGF-I lags considerably behind the sharp fall in plasma GH levels and expression of hepatic IGF-I mRNA.
