The positional cloning of genes underlying common complex diseases relies on the identification of linkage disequilibrium (LD) between genetic markers and disease. We have examined 127 polymorphisms in three genomic regions in a sample of 575 chromosomes from unrelated individuals of British ancestry. To establish phase, 800 individuals were genotyped in(More)
1. Poisoning is a common reason for presentation to hospital and hospital admission but there is no agreed policy for managing these patients. This study examined the management of patients presenting with poisoning and the factors affecting the probability of hospital admission and prolonged stay. 2. Data on all cases of poisoning presenting to six(More)
Activated mast cells reside in close apposition to T cells in some inflammatory processes. In this study, we analyzed whether this close physical proximity affects human mast cell degranulation and cytokine release. Thus HMC-1 human mast cells or primary bone marrow-derived human mast cells were cocultured with activated and with resting T cells. Mast cells(More)
1. A 12 week prospective survey of all patients of any age with confirmed or suspected poisoning presenting to six accident and emergency departments in the North East of England was performed to establish the local incidence and patterns of presentation of poisoning. 2. 945 episodes of poisoning involving 852 patients were recorded representing(More)
In total, 86 units were recorded from T2 and T3 left thoracic rami of cat. These receptors were located on the circumflex coronary artery, anterior descending coronary artery, and its adjacent myocardial regions. The conduction velocity of these fibres was in the range of "C" (0.5 to 1.8 m/s) and "A delta" (5.96 to 17 m/s) fibres. Out of these 86 units,(More)
Leishmania donovani, an intracellular protozoan parasite, challenges host defense mechanisms by impairing the signal transduction of macrophages. In this study we investigated whether interleukin-10 (IL-10)-mediated alteration of signaling events in a murine model of visceral leishmaniasis is associated with macrophage deactivation. Primary in vitro(More)
The ability of the Leishmanial parasite, UR6 (MHOM/IN/1978/UR6) to act as a immunoprophylactic and immunotherapeutic agent against experimental visceral leishmaniasis in a hamster model was tested. The Leishmanial parasite, UR6, lacked LPG but possessed abundant message for kinetoplastid membrane protein-11 (KMP-11), and failed to induce visceral infection(More)
The mechanism by which Giardia lamblia exerts its pathogenicity is likely to be multifactorial. A 58 kDa enterotoxin was purified and characterized from the excretory-secretory product (ESP) of the parasite (Kaur et al. 2001). In the present study an attempt has been made to elucidate the mechanism of action of the ESP, a potentially important enterotoxin.(More)
Atopy describes a syndrome of immunoglobulin E (IgE)-mediated allergy that underlies asthma and infantile eczema. We have previously identified a locus on chromosome 13q14 that is linked to atopy and to the total serum immunoglobulin A concentration. We have therefore made a saturation genetic map of the region by typing 59 polymorphic microsatellite loci(More)
1. Paracetamol is increasingly involved in self-poisoning in the United Kingdom and remains a common cause of fatal poisoning. 2. To document the epidemiology and early management of paracetamol poisoning data were collected on consecutive patients with suspected paracetamol poisoning presenting to 6 hospitals in the North East of England over 12 weeks in(More)
