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.

(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.

(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.
