OBJECTIVES To examine rates of culture proved tuberculosis in HIV infected patients in three specialist centres in north central London. METHODS Cases of tuberculosis in patients with previously documented HIV infection from 1990 to 1996 were identified retrospectively from microbiological/clinical records at Chelsea and Westminster, St Mary's, and University College London Hospitals. RESUL...

The constitutive active receptor (CAR) in mouse primary hepatocytes undergoes okadaic acid (OA)-sensitive nuclear translocation after activation by xenobiotics such as phenobarbital (PB) and 1,4 bis[2-(3,5-dichloropyridyloxy)]benzene (TCPOBOP). We have now mimicked this TCPOBOP-dependent and OA-sensitive translocation of mouse CAR (mCAR) in HepG2 cells and have demonstrated that protein phospha...

The secretory Na-K-Cl cotransporter NKCC1 is activated by secretagogues through a phosphorylation-dependent mechanism. We found a phosphorylation stoichiometry of 3.0 +/- 0.4 phosphorylated residues/NKCC1 protein harvested from shark rectal gland tubules maximally stimulated with forskolin and calyculin A, showing that at least three sites on the cotransporter are phosphorylated upon stimulatio...
