(1) Analysis of the chlC (narC) mutant, defective in the structural gene for nitrate reductase, revealed that heat treatment is not necessary for the expression of the active component.
(2) The induction of the narC operon encoding the nitrate reductase is coupled to the repression of the frd operon encoding the fumarate reductase.
(3) In addition, mutations in chlE, which are known to block the synthesis of the organic moiety of the Mo cofactor, lowered the threshold concentration of nitrate (< 1 micromole) necessary for frd repression and narC induction.
(4) Some issues and implications of the establishment of guidelines are briefly reviewed in the context of the NARC guidelines.
(5) Thing is man that this year the EU is including the shadow economy of narcs and prozzies and bad stuff like that as well as charity good fluffy things and it was like wow that the country has had a bumper year for both the good and bad shit and we are being punished for being so much better at this than all the other countries whose figures can’t be trusted anyway.” The point seemed to be that the government’s long-term economic plan was working thanks to drugs, hookers and soup kitchens.
(6) In chlB mutants, which are known to accumulate the Mo cofactor because of its failure to be inserted as a prosthetic group into proteins such as nitrate reductase, nitrate repression of frd and induction of narC were also intensified by molybdate supplementation.
(7) Following gonadectomy, TH activity increased significantly in the median eminence with no change in the periventricular (NPV), arcuate (NARC), and dorsomedial nuclei (NDM), or medial forebrain bundle (MF).
(8) Expression of narL does not require the fnr gene product, a pleiotropic activator that is required for full expression of narC, frd, and tor.
(9) Mutations in narL prevented the increase in activity in response to nitrate; mutations in chlB, narC, or narI resulted in partial constitutive expression of the chlD-lac fusion: the fusion was regulated by molybdate, but it no longer required the presence of nitrate for maximal activity.
(10) Under anaerobic conditions the narL gene product, in the presence of nitrate, is known to activate transcription of the narC operon, which encodes nitrate reductase.
(11) The protein-ligand complex appears to control narC positively but frd negatively.
(12) In the present study we found that a molybdenum coeffector acted synergistically with nitrate in the regulation of frd and narC.
(13) She says: “I’m Joan of Narc, patron saint of addicts.” Star Wars: The Force Awakens opens 17 December.
(14) You’re being a narc.” Assange now wears a beard.
(15) Several guidelines surrounding the use of behavioral procedures have recently appeared, the best of which is that of the National Association of Retarded Citizens (NARC).
(16) In chlD mutants believed to be impaired in molybdate transport (or processing), full repression of phi(frd-lac) and full induction of phi(narC-lac) by nitrate did not occur unless the growth medium was directly supplemented with molybdate (1 microM).
(17) arcuatus s. infundibularis - NARC), and posterior (nucl.
Nard
Definition:
(n.) An East Indian plant (Nardostachys Jatamansi) of the Valerian family, used from remote ages in Oriental perfumery.
(n.) An ointment prepared partly from this plant. See Spikenard.
(n.) A kind of grass (Nardus stricta) of little value, found in Europe and Asia.
Example Sentences:
(1) They sum up the various methods of prevention of venous stasis: Nard's method, associating bandages and deambulation, as well as various techniques of contention, hemodilution, compression with inflatable boots, electric stimulation or assisted mobilization.
(2) The signal perceived by the NARD appears to have been a valuable warning, rightly casting doubt on the safety of triazolam and the original dosage recommendations.
(3) In the course of 1979 the Netherlands Centre for Monitoring of Adverse Reactions to Drugs (NARD) received a remarkably large number of reports on patients with unusual and complex psychic disturbances, attributed to the use of the then recently marketed hypnotic triazolam.
(4) In consequence both cases were treated as outpatients by physical compression (Nard's method), without any anticoagulant medication : the results were striking and lasting.
(5) It is proposed that molecular oxygen controls the expression of nar via Fnr and that the nard mutation affects the Fnr binding site of the narGHI control region.
(6) The authors looked back at the original publications, that is to say to the publications of Chalier and of Nard, who described methods, which have been much referred to, that were quite exacting.
(7) The synergic effect of walking is definitively established; the treatment of deep-set phlebites by ambulatory compression is discovered by H. Fischer in Germany and then in France by L. Nard.
(8) The nard mutation, located upstream of the nar structural genes, was found to be cis dominant; it led to independence from the Fnr protein which, in the wild-type strain, exerts a strict positive control on the nar operon.
