13. Reconstruction of functionally normal and malignant human breast tissues in mice
The study of normal breast epithelial morphogenesis and carcinogenesis in vivo has largely used rodent models. Efforts at studying mammary morphogenesis and cancer with xenotransplanted human epithelial cells have failed to recapitulate the full extent of development seen in the human breast. We have developed an orthotopic xenograft model in which both the

14. Silicone breast prostheses and rheumatic symptoms: a retrospective follow up study.
OBJECTIVES--To determine whether women with silicone breast prostheses have more rheumatic complaints than controls. METHODS--The study included 287 women who had silicone breast prostheses implanted between 1978-90. For every patient a female control of the same age was selected who had had an aesthetic operation in the same year. A questionnaire was sent t

15. Silicone-specific blood lymphocyte response in women with silicone breast implants.
A blinded cross-sectional study was carried out with 99 women, 44 of whom had silicone breast implants. Group I consisted of 55 healthy volunteer women without breast implants; group II comprised 13 volunteer women with breast implants or explants who felt healthy; group III comprised 21 volunteer women with breast implants who had chronic fatigue, musculosk

16. Treatment of malignant obstruction of the superior vena cava with the self-expanding Wallstent.
BACKGROUND--Obstruction of the superior vena cava (SVC) in malignant disease can cause considerable distress to patients. Symptomatic relief can be achieved by the percutaneous implantation of a self-expanding stent (Wallstent) into the stenosis. METHODS--Fourteen patients with obstruction of the SVC were treated with one to three Wallstent endoprostheses. T

17. Antiestrogenic action of dihydrotestosterone in mouse breast. Competition with estradiol for binding to the estrogen receptor.
Feminization in men occurs when the effective ratio of androgen to estrogen is lowered. Since sufficient estrogen is produced in normal men to induce breast enlargement in the absence of adequate amounts of circulating androgens, it has been generally assumed that androgens exert an antiestrogenic action to prevent feminization in normal men. We examined the

18. Human adjuvant disease: remission of silicone induced autoimmune disease after explanation of breast augmentation.
Autoimmune diseases following silicone or paraffin implantation are rarely encountered complications of plastic surgery. A 42 year old woman is presented who developed clinical and immunological features of systemic lupus erythematosus 11 years after silicone augmentation. After explanation antinuclear antibody titres decreased from 1/1280 to 1/160, C4 compl

19. Treatment of a human breast cancer xenograft with an adenovirus vector containing an interferon gene results in rapid regression due to viral oncolysis and gene therapy.
Treatment of a human breast cancer cell line (MDA-MB-435) in nude mice with a recombinant adenovirus containing the human interferon (IFN) consensus gene, IFN-con1 (ad5/IFN), resulted in tumor regression in 100% of the animals. Tumor regression occurred when virus was injected either within 24 hr of tumor cell implantation or with established tumors. However

20. Interpopulational differences in progesterone levels during conception and implantation in humans
Clinical studies of women from the United States demonstrate a sensitivity of the ovarian system to energetic stress. Even moderate exercise or caloric restriction can lead to lower progesterone levels and failure to ovulate. Yet women in many nonindustrial populations experience as many as a dozen pregnancies in a lifetime despite poor nutritional resources

21. Tsg101 Is Essential for Cell Growth, Proliferation, and Cell Survival of Embryonic and Adult Tissues
Tumor susceptibility gene 101 (Tsg101) was identified in a random mutagenesis screen for potential tumor suppressors in NIH 3T3 cells. Altered transcripts of this gene have been detected in sporadic breast cancers and many other human malignancies. However, the involvement of this gene in neoplastic transformation and tumorigenesis is still elusive. Using ge

22. Whole-body and intravital optical imaging of angiogenesis in orthotopically implanted tumors
The development of drugs for the control of tumor angiogenesis requires a simple, accurate, and economical assay for tumor-induced vascularization. We have adapted the orthotopic implantation model to angiogenesis measurement by using human tumors labeled with Aequorea victoria green fluorescent protein for grafting into nude mice. The nonluminous induc
