Five regions of interest (ROIs) of size 5 × 5 mm (about 10 × 10 voxels), including one at the center and four at peripheral positions, were selected optionally to measure the mean in HU values.
The flood of dollars from just a single interest of modest size illustrates just how high the stakes are in this year's health care negotiations, and how even sideline issues generate intense lobbying.
The investment firm, Vestar Capital Partners, plans to keep the current management team in place while taking the largest shareholder position from a farmer-owner cooperative, which will retain a minority interest of undisclosed size.
The much lower likelihood of local adaptation in small populations reinforces the fundamental interest of population size for evolutionary theory.
The region of interest of fixed size was placed over the center of the nerve ring and fluorescence quantified.
Regions of interest of identical size were placed over nerve terminals, and the total fluorescence intensity was monitored over time.
Regions of interest of identical size were drawn in the cytosol and nucleus of each cell, and the nuclear/cytosolic ratio of NFAT-GFP was calculated.
Eleven volumetric regions of interest of equal size were defined (Fig. 3d), one within the lesion and ten within the "fully perfused myocardial tissue".
Fluorescence emission at the tumor location, given as relative units after normalization of maximal and minimal intensities, was measured with regions of interest of equal size at specified time points.
Using MATLAB (Mathworks, Natick, MA), a total of five nonoverlapping rectangular regions-of-interest (ROIs) of size >100 mm were placed per subject within areas of subjectively uniform texture in the right hepatic lobe (Couinaud segments IV VIII), avoiding artifacts, bile ducts, and vessels.
