Objectives: To assess the use of transvaginal sonography as a screening test for familial ovarian cancer and, secondarily, to determine the value of a family history of malignant disease and the potential role of serum CA 125 levels in the screening procedure.

Methods: Two thousand five hundred self-referred women were studied at the Ovarian Screening Clinic at King's College Hospital, London. These symptom-free women with at least one close relative who had developed ovarian cancer were studied prospectively.

A retrospective examination was made of archival data collected between 1940 and 1963 on the infection of mosquitoes with Plasmodium falciparum. Patients were undergoing malariatherapy for the treatment of neurosyphilis. A total of 913 lots of Anopheles quadrimaculatus and An.

The herpes simplex virus (HSV) glycoprotein heterodimer gE/gI plays an important role in virus cell-to-cell spread in epithelial and neuronal tissues. In an analogous fashion, gE/gI promotes virus spread between certain cell types in culture, e.g.

Aotus monkeys were infected with a strain of Plasmodium vivax from Panama to determine its potential for the testing of malarial vaccines. After sporozoite inoculation, 3 splenectomized Aotus nancymai that had been infected previously with Plasmodium falciparum and P. vivax had prepatent periods of 13, 15, and 15 days with maximum parasite counts of 12,726/microl, 5,310/microl, and 9,180/microl.

Owl (Aotus sp.) and squirrel (Saimiri sp.) monkeys are used frequently in malaria vaccine trials, during which the animals are monitored daily for parasitemia and general well-being.

We analyzed records of malaria therapy patients sequentially or simultaneously inoculated with Plasmodium falciparum and Plasmodium malariae. Gametocyte production was enhanced in P. falciparum by prior or concurrent P.

A retrospective examination was made of archival data on the response of Plasmodium malariae infections in humans to chloroquine. The clearance time for P. malariae was longer than that for P.

A retrospective analysis was made of clinical and parasitologic parameters in patients with induced Plasmodium ovale infection to document the initial clinical and parasitologic response and their subsequent development of clinical and parasitologic immunity, and to determine the effect of previous homologous and heterologous malaria on subsequent infection with this parasite. The prepatent periods were relatively uniform. Eight patients injected with sporozoites that had been stored frozen had a median prepatent period of 14 days (range = 14-20 days).

We examine the dynamics of parasitemia and gametocytemia reflected in the preintervention charts of 221 malaria-naive U.S. neurosyphilis patients infected with the St.

Objective: To provide evidence relevant to developmentally sensitive intervention and prevention of adolescents' psychosocial distress associated with treatment of type 1 diabetes.

Methods: We used self-reports on the Diabetes Quality of Life and SCL-90-R inventories administered at baseline, 1, and 3 years following adolescents' (n = 224) entry into the Diabetes Control and Complications Trial.

Results: Initiation of intensive treatment in early adolescence was associated with increasing school dissatisfaction; initiation in later adolescence resulted in marginal elevations in psychological distress.

Malaria therapy reinoculation data were examined for the possible detection of effects attributable to stable individual host-specific factors, through correlation between descriptive variables of first and second infections. Such an effect was demonstrated with respect to the first local maximum of the asexual parasite density, i.e.

Attempts were made to infect 4 species of New World monkeys (Saimiri boliviensis, Aotus nancymai, A. vociferans, A. azarae boliviensis) with Plasmodium gonderi, a malaria parasite of African monkeys.

Studies were conducted to determine the susceptibility of Anopheles farauti to different species and strains of Plasmodium. Mosquitoes were infected by feeding on animals or cultures infected with different strains of P. vivax, P.

Objectives: To evaluate the uptake and outcome of expectant management of spontaneous first trimester miscarriage in an early pregnancy assessment unit.

Participants: 1096 consecutive patients with a diagnosis of spontaneous first trimester miscarriage.

Methods: Each miscarriage was classified as complete, incomplete, missed, or anembryonic on the basis of ultrasonography.

A retrospective analysis was performed of parasite count data recorded from the first 7 days of blood or mosquito transmitted Plasmodium falciparum infections given for the treatment of neurosyphilis in the USA before 1963. The objective of this study was to characterize initial growth dynamics before host defences have significant effects on the infecting parasite population. Of the 328 patients' data available for analysis, 83 were excluded because they had received anti-malarial treatment during the first 7 days of the patent infection.

Immunity to Plasmodium falciparum in African children has been correlated with antibodies to the P. falciparum erythrocyte membrane protein 1 (PfEMP1) variant gene family expressed on the surface of infected red cells. We immunized Aotus monkeys with a subregion of the Malayan Camp variant antigen (MCvar1) that mediates adhesion to the host receptor CD36 on the endothelial surface and present data that PfEMP1 is an important target for vaccine development.

A strain of Plasmodium vivax from India was adapted to develop in splenectomized Saimiri boliviensis, Aotus lemurinus griseimembra, A vociferans, A. nancymai, A. azarae boliviensis, hybrid Aotus monkeys, and splenectomized chimpanzees.

Transmission-blocking vaccines against malaria parasites target molecules expressed by sexual stage parasites to elicit antibodies that prevent the infection of the mosquito vector. Pvs25 and Pvs28, expressed on the surface of ookinetes, are potential candidates for such a vaccine and induce antibodies that block the infectivity of Plasmodium vivax in immunized animals. To improve the ability to induce transmission-blocking antibodies, Pvs25 and Pvs28 were produced as a single fusion protein by the yeast Saccharomyces cerevisiae.

Attachment theory suggests, first, that patterns of dyadic behavior cohere across salient relationships and, second, that such linkages are mediated by working models, defined as cognitive/emotional representations of relationships abstracted from dyadic experience. In this longitudinal study, adolescents' (age 19) Adult Attachment Interview (AAI) coherence ratings and classifications (e.g.
