Dhat syndrome is a culture-bound syndrome of South-East Asia, common in young men. However, similar entity has also been described in female patients who attribute their symptoms to nonpathological or physiological vaginal discharge. The current diagnostic system for psychiatric illnesses does not encompass Dhat syndrome in females, and so these group of patients receive alternative diagnoses s...

Background Genomic imprinting is a heritable and developmentally essential phenomenon by which gene expression occurs in an allele-specific manner1. While the imprinted alleles are primarily silenced by DNA methylation, it remains largely unknown how methylation is targeted to imprinting control region (ICR), also called differentially methylated region (DMR), and maintained. Here we show that ...

BACKGROUND Culture-bound syndrome is a term used to describe the uniqueness of some syndromes in specific cultures. Dhat (semen-loss anxiety) has been considered to be an exotic 'neurosis of the Orient'. AIMS To ascertain the presence of similar symptoms and syndromes in different cultures and historical settings. METHOD Electronic and manual literature searches were used to gather informat...

An on-shell model for the supersymmetric index counting multiplicities of BPS states of the M5-brane theory is reviewed. In particular we explicitly study the tensionless Little String states appearing at intersections in a bound state of N 5-branes wrapped on a six-manifold with product topology M4 × T .

We study supersymmetry breaking caused by branes on anti-de Sitter space and obtain conditions for brane configuration not to break too many supersymmetries. Using the conditions, we construct a brane configuration corresponding to a baryon in large N gauge theory, and it is shown that the baryon is marginal bound state of quarks as is expected from supersymmetry. ∗[email protected]

S-duality symmetry of type IIB string theory predicts the existence of a stable non-BPS state on an orbifold five plane of the type IIB theory if the orbifold group is generated by the simultaneous action of (−1)FL and the reversal of sign of the four coordinates transverse to the orbifold plane. We calculate the mass of this state by starting from a pair of D-strings carrying the same charge a...

We construct p-brane solutions with non-trivial world volume metrics and show that applied to supergravity theories, they will lead to threshold BPS bound states of intersecting solutions. However applied to certain specific values of the couplings in cosmological (a, b)-models non-trivial solutions can be constructed. E-mail address: [email protected]

We examine the solutions of world-volume action for a D3-brane being put near other D3-brane which is replaced by the background configuration of bulk space. It is shown that the BPS solutions are not affected by the D3brane background, and they are interpreted as dyonic strings connecting two branes. On the contrary, the non-BPS configurations are largely influenced by the background D-brane, ...

We construct the exact noncommutative solutions on tori. This gives an exact description of tachyon condensation on bosonic D-branes, non-BPS D-branes and brane-antibrane systems. We obtain various bound states of D-branes after the tachyon condensation. Our results show that these solutions can be generated by applying the gauge Morita equivalence between the constant curvature projective modu...
