What's the difference between lobworm and lugworm?
Lobworm
Definition:
(n.) The lugworm.
Example Sentences:
Lugworm
Definition:
(n.) A large marine annelid (Arenicola marina) having a row of tufted gills along each side of the back. It is found burrowing in sandy beaches, both in America and Europe, and is used for bait by European fishermen. Called also lobworm, and baitworm.
Example Sentences:
(1) Lugworms, Arenicola marina (L.), acclimatized at 16-17 degrees C, were acclimated at temperatures between 5.3 and 25.7 degrees C for 96 h. Whereas in vitro Arenicola blood behaves like a Rosenthal system, in vivo prebranchial blood does not: the higher the acclimation temperature, the lower the pHv and [HCO3]V, PVCO2, remaining practically constant.
(2) Glycogenic metabolism of the lugworm A. marina was studied in vivo by 13C-NMR spectroscopy using 13C-labelled glucose.
(3) Lugworm protease C further purified by benzamidine-affinity chromatography, exhibited peptidase specificity for arginyl and lysyl bonds.
(4) Four cyclic AMP phosphodiesterase-activating activities, designated as A, B, C and D, were isolated from lugworm, Arenicola cristata, by preparative flat-bed isoelectric focusing.
(5) Oxygen consumption (MO2), haemoglobin oxygen saturation level (SVO2) and pH (pHv) in prebranchial blood were measured in lugworms experimentally confined in sea water at 15 degrees C. Total blood flow through the gills (Vb) was estimated.
(6) Lugworm GPase ab has shown a 2.4-fold higher specific activity as GPase b.
(7) 2) Freshly collected lugworms contained 3.5-3.8 mumol ATP, 0.8-1.0 mumol ADP, and 0.3-0.5 mumol AMP, as well as 4.5-4.7 mumol phosphotaurocyamine per g wet weight (energy charge 0.81-0.85).
(8) All the observed blood ABB variations reveal the complex intracellular processes through which the lugworm submitted to moderate osmotic shocks tentatively regulates, sometimes without any real success, its osmoticity and volume.
(9) Obviously, complementary physical, physiological and behavioral mechanisms allow the lugworm to live in sediments washed by almost fresh water during a 7-8 h 'low tide'.
(10) In the field, this phenomenon must occur at the beginning of high tide and must help to restore normal blood ABB in lugworms submitted to a moderate hyposmotic shock during low tide.
(11) Protein and iron concentrations and maximum combined oxygen concentration were measured in the blood of the lugworm Arenicola marina.
(12) Glycogen phosphorylase (GPase) from the body wall of the lugworm Arenicola marina (Annelida, Polychaeta) probably exists as a phospho-dephospho hybrid (GPase ab).
(13) The hybrid was identified by phosphorylation of purified lugworm GPase b (unphosphorylated form) with rabbit muscle GPase kinase and [gamma-32P]ATP.
(14) Lugworms were quite sensitive to the 1H-decoupling field used for obtaining the 13C(1H)-NMR spectra, especially at 11.7 T. Using bi-level composite-pulse decoupling and long relaxation delays, no tissue damage or stress-dependent phosphagen mobilization, as judged by 31P-NMR spectroscopy, was observed.
(15) On the other hand, in hypoxia lugworms the signal due to 13C-labelled glycogen decreased very rapidly proving a high turnover rate.
(16) The 13C of [1-13C]glucose, incorporated into glycogen, showed a very low turnover rate in normoxic lugworms as shown by two 13C(1H)-NMR spectra, one obtained 48 h after the other.
(17) Blood of the lugworm Arenicola marina studied in vitro behaved like a Rosenthal system: when temperature rose, pH decreased and PCO2 increased, whereas [HCO3] remained practically constant.
(18) This GPase ab produced by in vitro phosphorylation has shown similar dependences on AMP and caffeine as GPase extracted from the body wall of the lugworm.
(19) The kinetics of variations in the blood acid base balance (ABB) were investigated in a moderately euryhaline osmoconformer, the lugworm Arenicola marina (L.), exposed to natural and experimental hypo- or hyperosmotic shocks.
(20) Adenylate deaminase (AMP aminohydrolase, EC 3.5.4.6) from lugworm (Arenicola cristata) body-wall muscle was partially purified by extraction in KCl solutions and chromatography on phosphocellulose.
