The X-linked enzyme, glucose-6-phosphate dehydrogenase (G-6-PD) was used as a cellular marker to study the clonal characteristics of human atherosclerotic lesions from females heterozygous for G-6-PD isoenzymes. Portions of uninvolved aortic wall contained both isoenzyme types (A and B), and their isoehzyme patterns were used to establish criteria for polyclonal lesions. Portions of uterine lei...

We present progress on modeling of x-ray streak cameras with application to measurement of ultrafast phenomena. Our approach is based on treating the streak camera as a photocathode gun and applying modeling tools for beam optics and electromagnetic fields. We use these models to compare with experimental results from a streak camera developed at the Advanced Light Source. We also shows how thi...

This study was designed to determine the effects of a variety of naturally occurring saturated fats on aortic lesion formation in C57BL/6J mice that are susceptible to diet-induced fatty streak lesions. Groups of female mice were randomly assigned to one of seven treatment groups and were fed diets containing 15% (w/w) hydrogenated coconut oil, hydrogenated soy oil, hydrogenated palm oil, cocoa...

BACKGROUND In sparse-view CT imaging, strong streak artifacts may appear around bony structures and they often compromise the image readability. Compressed sensing (CS) or total variation (TV) minimization-based image reconstruction method has reduced the streak artifacts to a great extent, but, sparse-view CT imaging still suffers from residual streak artifacts. We introduce a new bone-induced...

Short-pulse measurements using a streak camera are sensitive to space-charge broadening, which depends on the pulse duration and shape, and on the uniformity of photocathode illumination. An anamorphic-diffuser-based beam-homogenizing system and a space-charge-broadening calibration method were developed to accurately measure short pulses using an optical streak camera. This approach provides a...
