Recent studies have shown that astrocytes are also infected in the brain but HIV-1 replication in these cells is restricted.

METHODS Biopsy revealed clusters of basaloid tumor cells with peripheral palisading, consistent with a superficial spreading variant of basal cell carcinoma. RESULTS The patient was treated with Mohs micrographic surgery, with clear margins achieved(More)

The patient had originally been treated for minimally invasive transitional cell carcinoma of the urinary bladder and ureteral orifices five years prior. Computerized tomography scan(More)
There is no cell proliferation in very sparcely plated chick embryo cell cultures. Substituting conditioned medium or adding of ethanol-fixed homologous cells to the cultures accelerates cell colony growth. The mechanism for the mitogenic action of fixed cells is considered to be the contact stimulation of cell proliferation, and addition of extra cells to(More)
