PURPOSE To compare magnetic resonance (MR) imaging with conventional imaging in screening high-risk women. MATERIALS AND METHODS This prospective trial included 192 asymptomatic and six symptomatic women who, on the basis of personal or family history or genetic analysis, were suspected or proved to carry a breast cancer susceptibility gene. RESULTS(More)
Soluble HLA-G (sHLA-G) molecules are found in the peripheral blood of healthy females and males, in cord blood and in amniotic fluids and discussed to be a mediator in maternal-fetal tolerance. In this study we investigated whether there are allele-specific differences in expression of sHLA-G molecules. For this, the sHLA-G plasma concentrations of 94(More)
Surges of luteinizing hormone (LH) that result in luteinization but occur prematurely with respect to the diameter of the leading follicle, prevent attempts to induce multiple follicular maturation for in-vitro fertilization (IVF) in a significant number of women. We examined the possibility of blocking premature LH surges by the administration of(More)
HLA-G, a nonclassical class I MHC molecule, is uniquely expressed on extravillous cytotrophoblasts of the maternal-fetal interface and is suggested to be essential for establishment of maternal-fetal immune tolerance. Although the level of polymorphism in HLA-G has originally been considered low, number, nature and site of polymorphisms seem to vary between(More)
In the present study, our first experiences with the ATP Tumour Chemosensitivity Assay (ATP-TCA), a novel method for pretherapeutic drug testing, are reported. During one year, a total of 111 samples obtained from patients suffering from different gynaecological malignancies (ovary: 53, breast: 41, others: 17) were sent for chemosensitivity testing. The(More)
The aim of the present study was to assess whether the induction of specific immune responses by vaccination with the murine monoclonal anti-idiotypic antibody ACA125, which imitates the tumor-associated antigen CA125, has a positive influence on the survival of patients with recurrent ovarian carcinoma. Forty-two patients with platinum-pretreated(More)
UNLABELLED The aim of this study was to evaluate the diagnostic accuracy of scintimammography with 99mTc-MIBI in patients with suspected primary breast cancer as monitored by SPECT or planar imaging. METHODS Patients with a suspect lesion detected by palpation or mammography were entered in the study. Excisional biopsy was performed on all patients and a(More)
Experimental perfusion of various organs has primarily been used in transplantation medicine to study the physiology, pathophysiology and metabolism of tissues and cells. The purpose of this study was to establish an experimental model for the extracorporeal perfusion of the human uterus with recirculation of a modified, oxygenated Krebs-Henselait solution,(More)
The apparent membrane capacity of tubular rabbit oocytes increases from 1.7-2.0 microF/cm2 before fertilisation to 3.7-4.0 microF/cm2 after fertilisation. The membrane conductivity measured on single cells was also increased by fertilisation from less than 1 mS/cm2 to 14 mS/cm2. Cells obtained from 2-, 4- or 8-cell embryos exhibited intermediate values of(More)
Human oocytes can be fertilized with high rates of success under in-vitro conditions even if only low numbers of spermatozoa are used. A culture system has been developed in which fertilization is performed in haematocrit capillary tubes (length 75 mm; i.d. 0.8-0.9 mm). Oocytes were fertilized in 5-10 microliters of different sperm suspensions containing a(More)
