We derive anomaly constraints for Abelian and non-Abelian discrete symmetries using the path integral approach. We survey anomalies of discrete symmetries in heterotic orbifolds and find a new relation between such anomalies and the socalled ‘anomalous’ U(1).
We formulate the effective field theory of a D-particle on orbifolds of T 4 by a cyclic group as a gauge theory in a V -bundle over the dual orbifold. We argue that this theory admits Fayet-Iliopoulos terms analogous to those present in the case of noncompact orbifolds. In the n = 2 case, we present some evidence that turning on such terms resolves the orbifold singularities and may lead to a K...
Polycomb group (PcG) genes encode evolutionarily conserved transcriptional repressors that are required for the long-term silencing of particular developmental control genes in animals and plants. PcG genes were first identified in Drosophila as regulators that keep HOX genes inactive in cells where these genes must remain silent during development. Here, we report the results of a genetic scre...
Immunoglobulin (Ig) class switch recombination (CSR) is initiated by the transcription-coupled recruitment of activation-induced cytidine deaminase (AID) to Ig switch regions (S regions). During CSR, the IgH locus undergoes dynamic three-dimensional structural changes in which promoters, enhancers, and S regions are brought to close proximity. Nevertheless, little is known about the underlying ...

The aim of this review article was to evaluate the relationship and the possible etiological mechanisms between endometriosis, leiomyoma (LM) and adenomyosis and gynecological cancers, such as ovarian and endometrial cancer and leiomyosarcoma (LMS). MEDLINE was searched for all articles written in the English literature from July 1966 to May 2013. Reports were collected systematically and all t...
