2021 Roadside weeds like wild mustard and Queen Anne’s lace, tendrils of palm inflorescence and carnivorous cobra lilies have all found a place in her work. 2021 Male sagos produce a yellowish, upright, often several feet tall inflorescence that deteriorates and drops off the plant in a matter of months. (20) S(+)-ibuprofen and R(-)-ibuprofen given alone more rapidly reached significantly higher maximal plasma concentrations than after the same doses of the racemic compound.Recent Examples on the Web Gradually, the inflorescence shatters and the plant produces new foliage.
(19) Consequently, racemic compounds showed approximately half potency of the corresponding enantiomers.(18) These data, coupled with the equilibrium fractionation factor for the 2-position of proline (which has been determined to be 1.17), provide the transition-state factors for each of the in-flight protons, and delineate the nature of the transition state(s) for the enzyme-catalyzed racemization.(17) Our results indicate that racemic EM 12 as well as its enantiomers are chemically and metabolically more stable than thalidomide however, extensive racemisation occurs both in vivo and in vitro.(16) The effects of the d- and l-isomers of pentazocine were compared to that of racemic pentazocine on contractions of the mouse isolated vas deferens.
(15) High-pressure liquid chromatographic (HPLC) methods have been developed for the determination of drug content, racemate A and related compounds in nadolol raw materials. (14) The vasodilating potency of d-alprenolol and d-propranolol was not significantly different from that of the respective racemic mixtures. (13) The racemic drug has unusual pharmacokinetic properties because of its concentration-dependent binding to plasma proteins in the therapeutic plasma concentration range. (12) Five diammine-Pt(II) or Pt(IV) coordination compounds, namely cis-diammine-dichloro-platinum (II) "cis-DDP", transdihydroxy-cis-diammine-dichloro-platinum (IV) "trans-ODDP", and derived substitution products of lactic acid (racemates or L-forms) with diminished toxicity in comparison to cis-DDP have been tested against mouse leukemia P388, and partly on melanoma B16 for antineoplastic activity. (11) Racemization of aspartic acid in dentin protein during the human lifetime progresses with age. (10) Decreasing the water concentration in the reaction medium by adding methanol at 0 degrees C drastically reduces the rate of racemization without affecting the rate of transamination. (9) The allene oxide also opens to a zwitterion, which undergoes charge delocalization to form a planar intermediate this structure is the achiral precursor of the stable end product of pericyclic ring closure, viz., racemic cis-12-oxo-PDA. (8) The assay is reliable to 0.1% racemate with a detection limit of approximately 100 pmol. (7) The antihypertensive and pulse-slowing effects of racemic propranolol, oxprenolol, pindolol, practolol and d-propranolol were assessed in 54 hypertensive patients. (6) The racemization-suppressing effect of other compounds were also evaluated by employing one of these model couplings to be at best only limitedly effective. (5) By this method, about 5.0 mg of racemic HCZ could be resolved completely in one run. (4) Racemic verapamil and the L- and D-isomer increased cellular vincristine accumulation to the same extent. (3) Routine enantiomeric analyses were successfully carried out on samples taken from animals dosed orally with the racemic drugs, providing important data on the possible levels of exposure to individual enantiomers during toxicity testing. (2) In contrast to the enantiomeric discrimination observed with racemic amine, the individual isomers were metabolized at approximately the same rate. (1) These results indicate that both racemic and L-baclofen inhibit trigeminal transmission in man, probably because they interfere with excitatory transmission through the interneurons of the lateral reticular formation. 
(n.) A flower cluster with an elongated axis and many one-flowered lateral pedicels, as in the currant and chokecherry.
