We discuss the field theory limit of Dp-branes. In this limit, the black Dpbrane solution approaches a solution which is conformal to adSp+2×S8−p. We argue that the frame in which the conformal factor is equal to one, the dual frame, is a ‘holographic’ frame. The radial coordinate of adSp+2 provides a UV/IR connection as in the case of the D3 brane. The gravitational description involves gauged...

24-Keto-1,25-dihydroxyvitamin D3 has been identified as an intestinal metabolite of 1,25-dihydroxyvitamin D3 by ultraviolet absorbance, mass spectroscopy, and chemical reactivity. The metabolite was produced from 1,25-dihydroxyvitamin D3 and 1,24R,25-trihydroxyvitamin D3 in rat intestinal mucosa homogenates. 24-Keto-1,25-dihydroxyvitamin D3 is present in vivo in the plasma and small intestinal ...

Results 1) Total of 92 children, 74(80.4%) had sufficiently catch up. 2) 69(75%) were fl/fl, 15(16.3%) were fl/d3 and 8 (8.6%) were d3/d3 the SGA groups, compared with 81%, 18%, and 1%, respectively in the Korean controls (P=0.04). 3) The highest catch up rate was seen in the fl/d3 subgroup(86.6%), the lowest in the d3/d3 subgroup (62.5%). The differences were not significant. 3)d3/d3 GHR genot...

Recent work has established a correspondence between the tripartite entanglement measure of three qubits and the macroscopic entropy of the four-dimensional 8-charge STU black hole of supergravity. Here we consider the configurations of intersecting D3-branes, whose wrapping around the six compact dimensions T6 provides the microscopic string-theoretic interpretation of the charges, and associa...

The N = 4 supersymmetric Yang-Mills (SYM) theory with gauge group SU(k) spontaneously broken to U(1)k−1 has a spectrum of 1/2 supersymmetric magnetic monopoles and dyons which, together with the ‘elementary’ particles of the perturbative spectrum, fill out orbits of an SL(2; Z) electromagnetic duality group. Each such particle has an interpretation in IIB superstring theory as an (m, n) string ...

An adequate vitamin D status is essential to optimize muscle strength. However, whether vitamin D directly reduces muscle fiber atrophy or stimulates muscle fiber hypertrophy remains subject of debate. A mechanism that may affect the role of vitamin D in the regulation of muscle fiber size is the local conversion of 25(OH)D to 1,25(OH)2 D by 1α-hydroxylase. Therefore, we investigated in a murin...

background: recent studies have shown the immunomodulatory effect of vitamin d3 through down-regulation of toll-like receptor (tlr) expression in human monocytes. in this study, the effects of vitamin d treatment on tlr2 and tlr4 expression on monocytes derived from type 2 diabetes was investigated. materials and methods: to assess the influence of vitamin d3 on expression of tlr2 and tlr4 on m...
