Postmenopausal hormone therapy increases mammographic density, a strong breast cancer risk factor, but effects vary across women. We investigated whether the effect of hormone therapy use is modified by polymorphisms in the estrogen receptor (ESR1) and progesterone receptor (PGR) genes in the Dutch Prospect-EPIC and the English EPIC-Norfolk cohorts. Information on hormone therapy use was obtain...

Gene polymorphism refers to a variation in DNA sequence that occurs population with frequency of 1% or higher. Polymorphism may be single nucleotide (SNP) some repetitive sequences (length polymorphism). Several methods can used analyze polymorphism, included Polymerase Chain Reaction (PCR), sequencing from the conventional method more sophisticated such as Next Generation Sequencing (NGS), flu...

We assign a relational structure to any finite algebra in canonical way, using solution sets of equations, and we prove that this is polymorphism-homogeneous if only the itself polymorphism-homogeneous. show polymorphism-homogeneity also equivalent property algebraic (i.e., systems equations) are exactly those tuples closed under centralizer clone algebra. Furthermore, aforementioned properties...

BACKGROUND Endometrial function is essential for embryo implantation. The aim of this study was to analyze gene expression profiles from individual endometrial samples obtained from women with repeated implantation failure after IVF in oocyte donation programs. METHODS Seventeen volunteers were recruited: women who had previously participated as recipients in oocyte donation cycles and repeat...

background: molecular components of the dopamine receptor (drd3) play an important role in the pathophysiology of schizophrenia (scz). previous studies have demonstrated an association between the drd3 ser9gly polymorphism and scz but the results have been inconclusive. method: in this study, we investigated this controversial association between the ser9gly (a/g) polymorphism and scz using mal...
