Differentiation and polarization of epithelial cells depends on the formation of the apical junctional complex (AJC), which is composed of the tight junction (TJ) and the adherens junction (AJ). In this study, we investigated mechanisms of actin reorganization that drive the establishment of AJC. Using a calcium switch model, we observed that formation of(More)
32 families informative for the segregation of Tuberous sclerosis (TSC) have been examined for genetic markers on chromosomes 9, 11, 12 and 16. In one large family there was clear evidence of linkage to markers on chromosome 16p13.3 (lodscore with D16S291 of 4.7 at theta = 0) but other families were too small to give individually convincing lodscores.(More)
Twenty-nine male breast cancers (MBC) were studied to determine the relationship between expression of several prognostic factors and clinical outcome. Immunohistochemistry employing a labeled streptavidin-biotin method was used to detect the presence of estrogen (ER) and progesterone receptors (PR), cathepsin D (CD), c-erbB-2 oncoprotein, epidermal growth(More)
The fruit fly Drosophila melanogaster was used to examine the mode of action of the novel insecticide and acaricide nodulisporic acid. Flies resistant to nodulisporic acid were selected by stepwise increasing the dose of drug in the culture media. The resistant strain, glc(1), is at least 20-fold resistant to nodulisporic acid and 3-fold cross-resistant to(More)
A nonamer peptide from murine nicotinic acetylcholine receptor delta chain (ACR delta), which shared four amino acid residues with a nonamer peptide of murine ovarian zona pellucida glycoprotein ZP3, induced murine autoimmune oophoritis and IgG autoantibody to the zona pellucida. Crossreaction between the ACR delta and ZP3 peptides was established by the(More)
Certain cancers exhibit derangement of de novo fatty acid biosynthesis, manifested as overexpression and hyperactivity of the lipogenic enzyme fatty acid synthase (FAS). Correlation of elevated FAS with high tumor grade and advanced stage in primary breast, prostate, and colorectal cancers has drawn attention to the enzyme as a possible marker of poor(More)
Over three months Cryptosporidium oocysts were identified in faecal samples from 43 (5%) of 867 patients presenting to their general practitioners with gastrointestinal symptoms. Cryptosporidium was the second most common enteric pathogen identified. Of the 867 patients, 329 were children aged under 5, of whom 24 (7%) excreted Cryptosporidium. A(More)
Since the introduction of routine measles, mumps and rubella immunization for children in England and Wales in 1988, the incidence of mumps has declined steadily. We describe an outbreak of mumps in 1996 attacking 34 of a cohort of 98 schoolchildren born in 1982 and 1983. This is the largest outbreak in the UK since the introduction of the vaccine into the(More)
We have previously shown the binding of low-density lipoprotein (LDL) to immobilized rat C-reactive protein (CRP) and the formation of a fluid-phase complex between these two proteins. In this report we used immunoelectrophoresis and agarose gel electrophoresis to show increased anodic migration of the LDL particle as a result of the modification of LDL by(More)
Fourteen people living in or near the city of Gloucester fell ill with Legionnaires' disease caused by Legionella pneumophila serogroup (SG) 1 between 27 August and 27 October 1986. Another patient had fallen ill on 30 May. Nine of the 15 were diagnosed retrospectively during a case finding exercise. There were three deaths. Three cases of Pontiac fever(More)
