Understanding the temporal origin(s) of schizophrenia, through specifying the earliest identifiable pathology, might indicate when to look for etiological factor(s), what their nature might be, and how course of illness might evolve from these origins. From this premise, earlier formulations are elaborated to offer a rigorously data-driven model that roots(More)
Two recent association studies have implicated the neuregulin-1 gene (NRG1) at chromosome 8p21-22 as a susceptibility gene for schizophrenia. Stefansson et al identified three 'at-risk' haplotypes (HapA, B and C) which spanned the NRG1 locus and shared a common core haplotype. Subsequently, they demonstrated evidence that the core haplotype was associated(More)
The D-amino acid oxidase (DAO) signaling pathway has been implicated in schizophrenia pathogenesis. This may be mediated through modulation of NMDA function by DAO, which is in turn activated by DAO activator (DAOA, formerly G72). Chumakov et al. (2002); PNAS 99: 13675-13680, identifying the novel schizophrenia susceptibility gene DAOA/G30 and a number of(More)
This study assessed the prevalence of involuntary movements among older inpatients with severe schizophrenia, many of whom had experienced a lifetime of illness and its treatment, and examined their neuropsychological correlates. The subjects of this study were 128 inpatients with a DSM-IV diagnosis of schizophrenia. They were assessed using the Abnormal(More)
A patient with cold-type autoimmune haemolytic anaemia for 8 years developed progressive B cell chronic lymphocytic leukaemia (CLL). Despite the risk of fludarabine induced exacerbation of haemolysis, he was given aggressive anti-CLL therapy with six courses of FCR (fludarabine 25 mg/m2 D1-3, cyclophosphamide 250 mg/m2 D2-4 and rituximab 375 mg/m2 D1) every(More)
The case of a 32-year-old man with a paravertebral mass and skin nodules, occurring against a background of immunosuppressive therapy for Crohn's disease, is presented. The tumours showed morphological and immunophenotypical features of plasmablastic lymphoma. To our knowledge, this is the first reported case of plasmablastic lymphoma presenting in this(More)
CONTEXT The serotonin transporter (SLC6A4) has been associated with several stress-related syndromes including posttraumatic stress disorder (PTSD). The ability to detect meaningful associations is largely dependent on reliable measures of preexisting trauma. OBJECTIVE To study the association of genetic variants within SLC6A4 with acute and posttraumatic(More)
OBJECTIVE Obesity is a significant public health problem in the United States, particularly among military veterans with multiple risk factors. Heretofore, posttraumatic stress disorder (PTSD) has not clearly been identified as a risk factor for this condition. METHOD We accessed both a national and local database of PTSD veterans. RESULTS Body mass(More)
To date, genome-wide single nucleotide polymorphism (SNP) and copy number variant (CNV) association studies of autism spectrum disorders (ASDs) have led to promising signals but not to easily interpretable or translatable results. Our own genome-wide association study (GWAS) showed significant association to an intergenic SNP near Semaphorin 5A (SEMA5A) and(More)
The regeneration of antibody-binding surfaces is of major importance for re-usable sensor formats such as required for direct 'real-time' biosensing technologies and is often difficult to achieve. Antibodies commonly bind the antigen with high avidity and may themselves be sensitive to regeneration conditions. The interaction of polyclonal(More)
