The discovery of leptin, the product of the obese (ob)-gene, has broadened the horizons of research on energy balance. This hormone, produced and secreted by adipose tissue and some placental cells, finds its way to the hypothalamus, where it binds to the leptin receptors and signals satiety through the neuroendocrine axis. The fact that adipose tissue is(More)
Between 1987 and 1990 27 women were observed who professed they did not know they were pregnant until term or until premature contractions set in. The aim of this study was to evaluate obstetric history and pregnancy outcomes and assess defence mechanisms and coping strategies which contribute to negation of pregnancy. In 11 women pregnancy was denied until(More)
Oral glucose tolerance testing (OGTT) and quantification of serum fructosamine levels were performed in 190 asymptomatic women in weeks 24-28 of pregnancy. OGTT identified 10 of the 190 women as having gestational diabetes, but serum fructosamine quantification failed to do so because none of these 10 women exhibited levels exceeding the normal limit of(More)
Extramedullary myeloid cell tumors are rare manifestations of acute nonlymphocytic leukemia (ANLL). While many advances in diagnosis have been made, dilemmas remain concerning the treatment of this disease. In primary extramedullary leukemia (EML) most reports agree upon a local therapy followed by systemic chemotherapy such as is used for ANLL. However,(More)
The case of a woman who died from cerebral metastasis of adenocarcinoma of the uterine corpus, clinical stage IA at the time of first referral, is described. Three months after preoperative endocavitary radiotherapy followed by radical surgery followed by postoperative radiotherapy, the 59-year-old patient developed neurological symptoms. A cerebral tumor(More)
Ultrastructurally, all cells of human fetal membranes strongly exhibit a large amount of lipid deposits throughout pregnancy. Their origin and function is still unknown. The aim of this study was to investigate the localization of key components of lipid metabolism in this tissue. Using immunohistochemical techniques, the distribution of lipoprotein lipase(More)
In the present study, we investigated the expression and localization of leptin receptors in human term placentae. On human term placenta tissue slices, digoxigenin-UTP labelled RNA-probe detected the long form of the leptin receptor ObR(L)mRNA in syncytiotrophoblasts of the villi, whereas the haematological subtype of the leptin receptor ObR/B219.1 was(More)
OBJECTIVE To determine whether fetal leptin levels correlate with fetal weight and whether such correlation is direct or indirect via insulin or human placental lactogen (hPL), respectively. DESIGN Cross-sectional study of offspring at term (n=175) with over-representation of large-for-gestational age (LGA; n=70) and small-for-gestational age (SGA; n=23)(More)
