In order to measure the intrafamilial correlation for age at onset and to examine gender resemblance among bipolar siblings, we assessed a sample of 130 bipolar patients belonging to 59 multiple affected sibships. To study the intrafamilial resemblance for age at onset and gender, we used the intraclass correlation and the sibship method, respectively.(More)
OBJECTIVE Preliminary data suggested that there are three subgroups of bipolar affective disorder based on age at onset. The authors sought to replicate those findings and determine the cut-off age of each subgroup. METHOD Admixture analysis was used to determine the best-fitting model for the observed ages at onset of 368 consecutively admitted patients.(More)
Thyroid hormones are major determinants of skeletal muscle differentiation in vivo. Triiodo-L-thyronine treatment promotes terminal muscle differentiation and results in increased MyoD gene transcription in myogenic cell lines; furthermore myoD and fast myosin heavy chain gene expression are activated in rodent slow twitch muscle fibers (Molecular(More)
The newly identified Sox gene family (Sry-like HMG-box gene) is characterized by a conserved DNA sequence encoding a domain of approx. 80 amino acids (aa) which is responsible for sequence-specific DNA binding. The first member isolated, the mammalian Y-linked testis-determining gene, Sry, is necessary and sufficient for male development. We report here the(More)
BACKGROUND Raised levels of total plasma homocysteine (tHcy) are associated with an increased risk of retinal vascular occlusive disease. A thermolabile form of a pivotal enzyme in homocysteine metabolism, methylenetetrahydrofolate reductase (MTHFR), has been associated with vascular occlusive disease and raised tHcy levels. The relation between(More)
The mechanisms responsible for development of inflammatory bowel disease (IBD) have not been fully elucidated, although the main cause of disease pathology is attributed to up-regulated inflammatory processes. The aim of this study was to investigate frequencies of polymorphisms in genes encoding pro-inflammatory and anti-inflammatory markers in IBD(More)
BACKGROUND Disturbances in central nervous system Na+, K+ adenosine triphosphatase (ATPase) activity have previously been proposed as being involved in the pathophysiology of bipolar mood disorder. METHODS We have examined one particular alpha subunit of this enzyme for allelic association in a sample of 85 Irish bipolar patients and 85 matched controls.(More)
BACKGROUND Recent data suggest that inflammatory reactions are involved in the pathogenesis of cerebral ischaemia. AIM To investigate whether certain inflammatory genetic polymorphisms are associated with the occurrence of ischaemic stroke. METHODS We investigated the prevalence of six polymorphisms in cytokine genes (IL-6, TNF-alpha, TNF-beta,(More)
OBJECTIVE To determine whether functional cytokine gene polymorphisms influence disease susceptibility and phenotype in patients with psoriatic arthritis (PsA). METHODS DNA was obtained from 147 PsA patients and 389 controls. Seven functional proinflammatory (interleukin-1beta [IL-1beta] +3953, IL-6 -174, tumor necrosis factor alpha [TNFalpha] -308,(More)
Patients with meningococcal disease have increased plasma levels of proinflammatory cytokines IL-6, IL-1beta, and TNF-alpha, with higher levels associated with fatal outcome. This study investigated whether polymorphisms in genes encoding these cytokines, and in those encoding anti-inflammatory IL-10 and IL-1Ra, are associated with the outcome in patients(More)
