Ratio of output to effort, or the ratio of effort produced to energy expended.

Conditions which affect the structure or function of the pupil of the eye, including disorders of innervation to the pupillary constrictor or dilator muscles, and disorders of pupillary reflexes.

Nerve structures through which impulses are conducted from a nerve center toward a peripheral site.

Neurons which send impulses peripherally to activate muscles or secretory cells.

The amount of plasma flowing to the parts of the kidney that have a function in the production of constituents of urine. It is the amount of plasma perfusing the kidney tubules per unit time, generally measured by p-aminohippurate clearance. It should be differentiated from RENAL PLASMA FLOW which is approximately 10% greater than the effective renal plasma flow. (Stedman, 25th ed; Dorland, 27th ed)

The amount of blood flowing to the parts of the kidney that are involved with the production of constituents of urine. It is that portion of the total renal blood flow that perfuses functional renal tissue (e.g., the glomeruli). It should be differentiated from RENAL PLASMA FLOW, EFFECTIVE which is based on the amount of plasma rather than on total renal blood. (Stedman, 25th ed; Dorland, 27th ed)

Factors that modify the effect of the putative causal factor(s) under study.

Calcium-binding motifs composed of two helixes (E and F) joined by a loop. Calcium is bound by the loop region. These motifs are found in many proteins that are regulated by calcium.

Peptide Elongation Factor G catalyzes the translocation of peptidyl-tRNA from the A to the P site of bacterial ribosomes by a process linked to hydrolysis of GTP to GDP.
