Since most oxygen exchange in muscle is thought to occur by diffusion across the walls of capillaries, it is important to determine the spatial relationship between capillaries and muscle fibers. We have extended the work of Kayar et al. (Microvasc. Res 24: 326-341, 1982) to include other statistical tests that allow one to make stronger statements… (More)
Mitochondrial volume density and lipid droplet-volume density were stereologically determined from electron micrographs of muscle fibers from three hamster muscles: retractor, sartorius, and soleus. The number of capillaries around a fiber, length of capillary-fiber contact, and muscle fiber area were also measured. Glycolytic fibers of the retractor and… (More)
The purpose of this study was to 1) determine the threshold volume of coronary microemboli (<120μm) needed for reproducible visualization of microinfarcts on contrast enhanced MDCT and MRI and 2) assess the impact of microemboli volumes on myocardial perfusion and left ventricular (LV) function.
