The metallothioneins in vitro are both effective free radical and transitional metal ion scavengers. For this reason we investigated the expression of this protein in the normal CNS and after ischaemia using a monoclonal anti-metallothionein antibody to metallothionein isoforms I and II. Using immunohistochemistry and confocal laser scanning microscopy, we(More)
Granular deposits of C9 and the terminal complement complex, measuring 0.3-1.2 microns, have been demonstrated immunocytochemically in association with capillary endothelial cells, predominantly within plaques and adjacent white matter, in tissue obtained at autopsy from 5/7 patients with multiple sclerosis (MS) and one individual with subacute sclerosing(More)
To elucidate the protein composition of the nemaline bodies present in the muscle fibres of patients with congenital nemaline myopathy (CNM), we studied muscle biopsies with monoclonal antibodies against alpha-actinin and desmin in combination with a modified Gomori trichrome method. Electron microscopy of immunolabelled resin embedded sections was used for(More)
By using a double-affinity-purified first antibody and colloidal gold-conjugated second antibody, it is shown that calpain I (a cysteine proteinase activated by micromolar concentrations of Ca2+) has a predominant intracellular location in the I-band region of the extensor digitorum longus (EDL) muscle of the rat, but is not exclusively associated with the(More)
The role of metallothionein (MT) in the brain in heavy metal detoxification is relatively unexplored. Brain copper (Cu) elevation although unusual in chronic Cu poisoning in sheep, has been shown to occur after treatment with the chelating agent ammonium tetrathiomolybdate (TTM). The aim of this study was to investigate the expression of MT in TTM(More)
Metallothioneins (MTs) are metal binding proteins overexpressed in various human neoplasms which are associated with resistance to cytotoxic drugs. A series of 156 archival human brain tumours were investigated immunohistochemically for expression of MTs; these included 10 low-grade gliomas, 44 high-grade gliomas, 98 meningeal tumours (19 classical, 30(More)
Next Steps Toward Space Security 109 James Clay Moltz ii iii Foreword As an increasing number of countries use space systems to advance their scientific, technological, social, economic, and national security interests, there is a parallel increase in attention to how best to ensure that those systems can operate free of threats of disruption. To date, that(More)
The clinical management of neuroendocrine tumours is complex. Such tumours are highly vascular suggesting tumour-related angiogenesis. Adenosine, released during cellular stress, damage and hypoxia, is a major regulator of angiogenesis. Herein, we describe the expression and function of adenosine receptors (A1, A2A, A2B and A3) in neuroendocrine tumours.(More)
The proopiomelanocortin (POMC) gene is highly expressed in the pituitary gland where the resulting mRNA of 1200 base pairs (bp) gives rise to a full-length protein sequence. In peripheral tissues however both shorter and longer POMC variants have been described, these include for example placental tissue which contain 800 (truncated at the 5' end) and 1500(More)
Using five monoclonal antibodies against different parts of the dystrophin molecule, we have studied the dystrophin composition of 17 dystrophin-positive fibres in a muscle biopsy from a boy with Xp21 muscular dystrophy of Duchenne-type severity. The fibres showed five distinct, reproducible, immunoreactive dystrophin profiles. All the profiles included(More)
