Thus, there are multiple possible pathways that might lead to selective alteration in rates of synthesis or metabolism of some classes of serum lipids.
The purpose of this study was to determine the effect of alterations in rate of limb movement on Phase III ventilation during exercise, independent of metabolic rate, gait style, and treadmill incline.
These downstream changes may contribute to the complex abnormalities in contractile performance found in CLC-1 deficient muscle, in particular changes that occur during the contractile phase of the contraction-relaxation cycle, such as impaired force production and alterations in rate of fatigue during isometric contractions [ 19].
The transition from normal to malignant epithelial tissue involves many morphological changes, such as cellular depolarisation, loss of cellular junctions and alterations in rates of proliferation and apoptosis (Debnath and Brugge, 2005).
Significantly, because no overt developmental effects are associated with aberrant AKH signaling under non-stressed conditions, it is particularly amenable to genetic screens because data interpretation is unencumbered by alterations in rates of development.
However, it is not likely that lower Cort levels caused these changes, as when HG treated pregnant rat dams were supplemented with Cort, we found no effect on rates of glucose oxidation or lipogenesis in any of the three tissues (Patel et al., 2008), thus indicating that the lower levels of Cort alone do not cause the observed alterations in rates of glucose oxidation and lipogenesis.
At a finer level, some gradients clearly are subject to independent alteration in rate and tempo of expression along the body axis some progress incrementally along the segmental series, some commence abruptly and then progress slowly and these properties vary across taxa.
Hence, in cyclotrons the protons' path changes as energy increases, whereas in synchrotrons the protons are held in a constant path via changes in the strength of the magnetic field and alteration in the rate of voltage oscillation.
For example, glucose-6-phosphate dehydrogenase (G6PD) protein levels and activity are positively regulated by intake of carbohydrates, but without any alteration in transcription rate of the associated G6pdx gene [ 61].
Assuming that the lens thickness and curvatures remain unchanged, as observed in practice, it appears possible to account for initial hyperopic refractive shifts of up to a few diopters by reduction in refractive index near the lens center and alteration in the rate of change between center and surface, so that most of the index change occurs closer to the lens surface.
