The relative positions of the positive cells in the crypt were noted.

In the remaining 10 control patients, there were occasional positive cells scattered throughout the lamina propria.

Occasionally positive cells in the villus tips, compatible with small bowel macrophages, were detected.

The percentage of cells positive for production of 11-4, 11-6 and 11-10 was extremely low.

The number of positive cells was expressed as a percentage of total cells counted in ten randomly selected high power fields.

The number of positive and negative cells were counted visually in three sample lengths per section (i.e. 840 μm).

Varying the spacing between a telephoto's front positive and rear negative cells changes the lens' magnification.

We were therefore interested to determine the precise localization of the Tnfrh1 -positive cells in this organ.

Connecting the positive of one cell to the negative of the next cell is called connecting them in series.

A positive cell potential gives a negative change in Gibbs free energy.
