Lead content of ovarian follicular fluid obtained from 23 women was determined by atomic absorption spectrophotometry. In an in vitro experiment the direct effect of lead on the morphology and on progesterone (P) production by cultured granulosa cells of six women was investigated. Follicular fluid and granulosa cells were obtained from follicular aspirates(More)
Cadmium (Cd) is able to decrease preovulatory luteinizing hormone (LH) levels in blood and inhibit ovulation in rats. In this study the direct effects of Cd on steroidogenesis in granulosa cells were investigated. The cells obtained from ovarian follicular aspirates of 41 women undergoing in vitro fertilization (IVF) were cultured. Cadmium-induced(More)
The classical AH8.1 (HLA-A1-B8-DR3-DQ2) is the most common Caucasian haplotype, associated with several autoimmune diseases, immunologic hyperreactivity and rapid progression to the acquired immunodeficiency syndrome. However, in Asian Indians, there are multiple unique B8-DR3 haplotypes that are associated with autoimmunity and differ significantly from(More)
The clinical and laboratory data from a cross-sectional and a longitudinal study of healthy individuals between 50-89 years of age and that of centenarians were compared. The examination showed that in healthy elderly subjects and centenarians most of the clinical laboratory findings were in the normal range. However, age-related changes could be observed(More)
OBJECTIVE To compare the clinical parameters, C-peptide levels, pattern of islet cell-specific autoantibodies, and prevalence of predisposing genotypes in subjects with latent autoimmune diabetes in adults (LADA) and those with adult-onset type 1 diabetes with rapid progression. RESEARCH DESIGN AND METHODS We evaluated the clinical parameters, C-peptide(More)
Previously we reported on strong linkage disequilibrium (LD) between the mono-S-C4B-RCCX module (mono-S) and the TNF2 allele (both known constituents of the 8.1 ancestral haplotype (8.1 AH)) in two Caucasian populations. The gene for the receptor of advanced glycation endproducts (RAGE) is encoded between the RCCX module and the HLA class II genes in the(More)
The incidence of allotypes of the genes of the fourth component (C4) and factor B of the complement system was compared in 252 persons under 45 years of age ("young" group) with 482 people between 61 and 90 years of age ("old" group). One hundred people older than 90 years of age (nonagenarians) were also investigated. A striking difference was found(More)
Polymorphisms in the CTLA4 gene region have been associated with susceptibility to autoimmune diseases. The recently described single nucleotide polymorphism CT60, located in the 3' untranslated region of CTLA4 is associated with Graves' disease, thyroiditis, autoimmune diabetes and other autoimmune diseases. A case-control association study was conducted(More)
Natural antibodies of IgM or IgG types are present in sera of most healthy individuals and are important participants of the immune response. Little is known, however, about the genetic regulation of their plasma levels in humans. We determined the concentrations of three IgM type natural autoantibodies (NAAbs) reactive to certain conserved self-antigens(More)
