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; ...
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 ...
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). ...
Variation in myoplasmic Ca2+ concentration during contraction and relaxation studied by the indicator fluo-3 in frog muscle fibres
(1994-07-01)
1. The fluorescent dye fluo-3, in its permeant acetoxymethyl form, was used to monitor calcium transients during twitch and tetanus of single fibres isolated from the anterior tibialis muscle of Rana temporaria (2-5 degrees ...
Myofibrillar fatigue versus failure of activation during repetitive stimulation of frog muscle fibres
(1992-11)
1. Single fibres isolated from the anterior tibialis muscle of Rana temporaria (temperature, 2-5 degrees C; sarcomere length, 2.10 microns) were fatigued using two separate protocols that led to different degrees of ...
Changes in force and stiffness induced by fatigue and intracellular acidification in frog muscle fibres
(1990-05)
1. Changes in force and stiffness were recorded simultaneously during 1 s isometric (fixed ends) tetani of single fibres isolated from the anterior tibialis muscle of Rana temporaria (temperature 1-3 degrees C; sarcomere ...
