2,3-Butanedione monoxime increases speed of relaxation in single muscle fibres of frog
(2001-05)
The effects of 2,3-butanedione monoxime (BDM) on intracellular Ca2+ transient and cross-bridge function were studied in frog single fibres from the anterior tibialis muscle of Rana temporaria (sarcomere length, 2.2 microm; ...
Anopheles stephensi Dox-A2 shares common ancestry with genes from distant groups of eukaryotes encoding a 26S proteasome subunit and is in a conserved gene cluster
(2000-06)
The sequence of a cloned Anopheles stephensi gene showed 72% inferred amino acid identity with Drosophila melanogaster Dox-A2 and 93% with its putative ortholog in Anopheles gambiae. Dox-A2 is the reported but herein ...
Heat production and oxygen consumption during metabolic recovery of white muscle fibres from the dogfish Scyliorhinus canicula
(2000-04)
Oxygen consumption and heat production were measured during contraction and recovery of isolated, white muscle fibres from dogfish (Scyliorhinus canicula) at 19 degrees C. The contraction period consisted of 20 isometric ...
Contraction with shortening during stimulation or during relaxation : how do the energetic costs compare?
(1998-10)
White muscle fibres from dogfish were used to compare the energetic costs of shortening by fully active muscle and by relaxing muscle. The muscle preparation was tetanized for 0.6 s and shortened either during stimulation ...
A sex-linked Ace gene, not linked to insensitive acetylcholinesterase-mediated insecticide resistance in Culex pipiens
(1998-05)
An acetylcholinesterase (AChE) gene, Ace.x, showing 93% identity of deduced amino acid sequence to Anopheles stephensi Ace has been cloned from a Culex pipiens strain homozygous for insensitive AChE (iAChE) mediated ...
Shortening during stimulation vs. during relaxation : How do the costs compare?
(1998)
White muscle fibres from dogfish were used to investigate the energetic cost of shortening by fully active muscle and by relaxing muscle. The muscle preparation was tetanized for 0.6 s and shortened by 1 mm (about 15% L0) ...
Genetic differentiation between and within strains of the saw-toothed grain beetle, Oryzaephilus surinamensis (Coleoptera Silvanidae) at RAPD loci
(1997-08)
Nine strains of Oryzaephilus surinamensis have been kept in laboratory culture for periods ranging from 5 to 30 years (30-180 generations). Two RAPD primers provided sufficient information to separate the strains reliably ...
The relationship between the intracellular Ca2+ transient and the isometric twitch force in frog muscle fibres
(1996-09)
The calcium-sensitive fluorescent indicator fluo-3 was used to monitor the intracellular free calcium concentration ([Ca2+]i) during isometric twitches in twenty-nine single muscle fibres from the anterior tibialis muscle ...
Structural features of a close homologue of L1 (CHL1) in the mouse: a new member of the L1 family of neural recognition molecules
(1996)
We have identified a close homologue of L1 (CHL1) in the mouse. CHL1 comprises an N-terminal signal sequence, six immunoglobulin (Ig)-like domains, 4.5 fibronectin type III (FN)-like repeats, a transmembrane domain and a ...
The effects of 2,3-butanedione monoxime (BDM) on the force-velocity relation in single muscle fibres of the frog
(1995-04)
The effects of 2,3-butanedione monoxime (BDM) on the force-velocity relation were studied in single fibres from the anterior tibialis muscle of Rana temporaria (2.2 microns sarcomere length, temperature 1.9-2.4 degrees C). ...
