We have developed a model for congenital syphilis in the rabbit. This report provides additional information on newborn tissue pathology in animals that were infected in utero. A total of 35 pregnancies were evaluated, each containing 6 to 12 newborns. In the infected group, the mortality was approximately 50%; of the live newborns, half appeared normal and(More)
We examine determinants of the nearly 30 percent increase in the average age of domestically produced, registered automobiles since the mid-1960s. We find that very little of the increase in car longevity is attributable to improvements in the inherent durability of cars. Rather, we find that the temporal pattern of longevity improvement is highly(More)
Background: HERG potassium channel blockade is the major cause for drug-induced long QT syndrome, which sometimes cause cardiac disrhythmias and sudden death. There is a strong interest in the pharmaceutical industry to develop high quality medium to high-throughput assays for detecting compounds with potential cardiac liability at the earliest stages of(More)
