Inactivity periods and postural change speed can explain atypical postural change patterns of Caenorhabditis elegans mutants

Postural pseudoanemia: posture-dependent change in hematocrit.

OBJECTIVE To determine the magnitude of posture-related changes in blood components. SUBJECTS AND METHODS Twenty-eight healthy subjects were studied between 1995 and 2004 at the Vanderbilt Autonomic Dysfunction Center, Nashville, Tenn. Lying and standing plasma volume (PV) and hematocrit (Hct) values were determined for each subject. RESULTS Individual PV decreases on standing ranged from 6...

Which Postural Control and Functional Movement Screen Values Related to Change of Direction Runs?

Background. Instead of different measurements of physical performances such as postural control, strength, and flexibility, studies investigating many abilities such as the harmony between these abilities and body segments simultaneously with the test FMS results and different physical relationships were performed. Meaningful results and other relationships between COD, FMS, and PC have previou...

Central control of postural orientation in flatfish. I. Postural change dependence on central neural changes.

Postural change and intraocular pressure in glaucomatous eyes.

Several authors (Anderson and Grant, I973; Galin, Mclvor, and Magruder, I963; HetlandEriksen, I966; Kriegelstein and Langham, 1975a; Roberts and Rogers, I964; Tarkkanen and Leikola, I967) have reported that in normal subjects and in glaucomatous patients the intraocular pressure (IOP) in the supine position is about 2-5 mmHg higher than in the seated position. The measurements were carried out ...

Mechanisms of initial blood pressure response to postural change.

The influence of supine rest on the blood pressure response to standing and 70 degrees head-up tilt was studied in detail for the first 30 s after the change of posture. Following 20 min of supine rest, the active transition to standing was accompanied by an immediate increase in systolic pressure of 29 +/- 6 mmHg (mean +/- SEM). This was followed by large fluctuations in systolic pressure: to ...
