Computer-assisted clinimetric tool for the study of facial expression: a pilot validity study.

Clinimetrics is the measurement of clinical phenomena; more specifically, it is mensuration, the act of acquiring and labeling basic raw data that is used to describe or measure symptoms, signs, and other distinctly clinical phenomena. Over the last 5 years, a new computer method for measuring facial expression has been developed. Refinement and validation of this technique are necessary before clinical applications are appropriate. Four hundred fifty data points from two human observers and the computed method were compared with one another by using indices of location, dispersion, and association within the framework of the logical construct of validity. These results suggest that the computed method is valid. This new method may be nearly ready for clinical applications as a primary or adjunctive clinimetric tool.

A growth-responsive gene (16C8) in normal mouse fibroblasts homologous to a human collagenase inhibitor with erythroid-potentiating activity: evidence for inducible and constitutive transcripts.

We present the DNA sequence of an essentially full-length cDNA clone of 16C8, a growth factor-inducible gene isolated from a mouse embryo fibroblast cDNA library. The 0.9-kb mRNA encodes an Mr 22,500 protein that has substantial homology to a human protein with the reported abilities to potentiate erythroid differentiation and to inhibit collagenases and other tissue metalloproteinases. The N-terminus of the predicted protein has a hydrophobic nature characteristic of secreted proteins, and two potential sites for N-linked glycosylation are present. The cytoplasmic concentration of 16C8 mRNA is maximal in mid G1 at about 6 h after serum stimulation of quiescent fibroblasts. Northern blot analysis showed a progressive reduction in the size of the induced 16C8 transcripts with increasing time after serum stimulation. This was shown to be due to the reduction in length of the poly(A) tails. S1 analysis of the 5' portion of the mRNA revealed the presence of three different species of transcript, only one of which was inducible.
