Although serological reactivity to human papillomavirus type 16 (HPV-16) proteins has been demonstrated in patients with invasive cervical carcinoma, the degree of seroreactivity to these proteins in women with preinvasive disease and its relationship to the HPV type associated with the disease are unclear. We obtained sera from 27 women undergoing cone(More)
Blood flow and uptake of two nutrient analogues have been studied in the neural retina, pigment epithelium and optic lobes of 5-7-day-old chicks after systemic administration of isotopically labeled compounds. The pigment epithelium accumulated the inert amino acid, alpha-aminoisobutyric acid, 6 times as effectively on a wet weight basis than did the neural(More)
Membranes prepared from the retinal pigment epithelium of several species possess a specific site which binds [3H]strychnine. This binding has a somewhat lower affinity and a much greater density than the corresponding interaction in the hindbrain or neural retina. Binding is not greatly altered in the presence of 10−3 M glycine,l-alanine, β-alanine,(More)
