OBJECTIVE Current research on the etiology of thin-ideal internalization focuses on psychosocial influences (e.g., media exposure). The possibility that genetic influences also account for variance in thin-ideal internalization has never been directly examined. This study used a twin design to estimate genetic effects on thin-ideal internalization and(More)
Although the fluorescent treponemal antibody absorption (FTA-ABS) test has found wide application in the diagnosis of syphilis, the cerebrospinal fluid fluorescent treponemal antibody (CSF-FTA) test is still controversial in the diagnosis of neurosyphilis. We found the CSF-FTA test extremely sensitive to contamination with FTA-ABS-reactive blood at(More)
