Plasma-Plasma Third Order Phase Transition from Type IIB Supergravity.

We show that the planar, charged black hole in asymptotically anti-de Sitter spacetime, dual to the strongly coupled quark-gluon plasma thermal state of large N, SU(N), N=4 super Yang-Mills at finite chemical potential undergoes a third-order phase transition in the grand canonical ensemble to a hairy black hole of type IIB supergravity. The hairy phase is another strongly coupled fluid with a conformal equation of state and can be interpreted as another kind of quark-gluon plasma. This new quark-gluon plasma has less entropy and, therefore, seems to characterize some form of smooth hadronization.

Heat shock proteins HSP27 and HSP70 in unilateral obstructed kidneys.

Unilateral ureteropelvic junction obstruction (UPJO), a condition involving injury to the kidney, leads to vasoconstriction, macrophage infiltration, oxidative stress, and tubulointerstitial fibrosis. In the present study we analyzed in 22 children, the impact of UPJO on expression of HSP27 and HSP70 and related the changes to renal function and duration of obstruction. Kidney function was evaluated, and renal biopsies were obtained for immunohistochemical and western blot analyses at the time of surgery.
