Mastication of verruca vulgaris associated with esophageal papilloma: HPV-45 sequences detected in oral and cutaneous tissues.

Human papillomaviruses (HPVs) are double-stranded, circular, epitheliotropic DNA viruses of which nearly 70 types have been identified. Specific HPV types exhibit a predilection to infect certain sites; however, occurrence is not unique or restricted to these sites. HPV typing may also be helpful in determining the oncogenic potential of HPV lesions.

U1RNP positive neonatal lupus erythematosus: association with anti-La antibodies?

Neonatal lupus erythematosus (NLE) is an antibody-mediated disorder most commonly associated with autoantibodies to Ro and/or La antigens. There have been five previous reports describing eight NLE patients with anti-U1RNP antibody in the absence of anti-Ro and anti-La autoantibodies. We report two cases of anti-U1RNP antibody-positive NLE, and briefly review the five previous reports.

Cutaneous-malignancy and leprosy. Report of a patient with Mycobacterium leprae and basal cell carcinoma concurrently present in the same lesion.

Background: Leprosy is a chronic systemic infection caused by the bacillus Mycobacterium leprae. Cutaneous neoplasms have been observed in patients with leprosy. Also, albeit less commonly, M.

Hormonal regulation of the synthesis and mRNA content of the regulatory subunit of cyclic AMP-dependent protein kinase type II in cultured rat ovarian granulosa cells.

These studies were undertaken to determine the molecular events by which estradiol and follicle-stimulating hormone (FSH) stimulate in ovarian granulosa cells the increase in the content of one of the regulatory subunits of cAMP-dependent protein kinase type II, RII51 (Mr = 51,000), and its electrophoretic variants RII51.5 (Mr = 51,500) and RII52 (Mr = 52,000). To analyze the de novo synthesis of RII51/52, granulosa cells were cultured (10(6) cells/ml) for 0, 12, 24, or 48 h with estradiol (10 nM) +/- FSH (12.

Cholesterol side-chain cleavage P450 messenger ribonucleic acid: evidence for hormonal regulation in rat ovarian follicles and constitutive expression in corpora lutea.

Using an affinity-purified antibody against cholesterol side-chain cleavage P450 (P450scc) and a human P450scc cDNA probe, 11 rat P450scc cDNA clones were identified and isolated from our rat granulosa cell lambda gt11 cDNA expression library. Two clones were plaque purified and subcloned into pBR322. One of these P450scc cDNA clones, approximately 1.
