A double-flash microphotographic technique has been used to follow the variation with temperature of the following kinetic parameters related to the contraction and re-extension of the ciliate Stentor coeruleus, namely the rate of contraction, the initiation time before contraction, the rate of re-e

β¦ Synopsis
Recent theories of inuscular contraction have placed considerable importance on the p a r t played by passive viscoiiselastic factors in the determination of the time course of the response to stimulation. Rozler ('41)' for example, has reported that the time-course of isometric relaxation agrees exactly with that of the decay of tension after stretch. H e concludes that relaxation is controlled by the viscous properties of the contractile elements. Schoepfle (personal communication) has found that when the neck retractor ( a

## Abstract The active lengthβtension relation was determined for the left digastric muscle of seven New Zealand White rabbits anesthetized with pentobarbital. Measurements of muscle length and fiber architecture were made from photographs of resting and actively contracting muscle. There was a mar
## Abstract ## Aims To characterize the detrusor muscle of the mouse urinary bladder in order to understand more precisely spontaneous contractile behavior of this organ. This study examined the spontaneous electrical activity and Ca^2+^ dynamics of the detrusor smooth muscle and investigated the
Xanthorrhizol, xanthorrhizol glycoside, and trachylobanoic acid, compounds isolated from medicinal plants that are grouped in the complex known as Cachani have been shown to inhibit the tonic contraction of rat uterus induced by: (a) depolarizing K solution (60 mM), (b) CaCl 2 (1 mM), and (c) BAY K
## Abstract ## Objective To investigate whether there are differential effects of disease activity and damage on physical functioning as measured by the Health Assessment Questionnaire (HAQ) over the course of psoriatic arthritis (PsA). ## Methods Between June 1993 and March 2005, 382 patients a
