Mortality rates for horses that have undergone emergency abdominal surgery are higher than for other procedures. Here, multivariable modelling of data from 774 surgical colic cases is used to identify pre-operative and anaesthesia-related variables associated with intra- and post-operative mortality. Intra-operative mortality was significantly (P<0.05), and(More)
The records of 496 orthopaedic operations on 428 horses were reviewed to estimate the prevalence of, and identify the risk factors for, the development of colic in horses after surgery. Colic was defined as any recognised sign of abdominal pain that could not be attributed to a concurrent disease. Fourteen of the horses developed colic; eight of them were(More)
OBJECTIVE To evaluate the immune response to HIV-1 p24 generated in vivo by p17/p24:Ty virus-like particles (p17/p24:Ty-VLP) by examining the lymphoproliferative and antibody (Ab) responses to HIV-1 p24, as well as Gag-specific cytotoxic T lymphocytes (CTL), in HIV-seronegative volunteers immunized with hybrid p17/p24:Ty-VLP. DESIGN AND METHODS Sixteen(More)
General anesthesia in horses carries an increased risk of morbidity and mortality compared with other species. In recent years the number and complexity of epidemiologic studies in equine anesthesia has increased. The ability to interpret such studies and understand epidemiologic terminology is vital for veterinarians for them to make potential improvements(More)
The self-assembly properties of a protein encoded by the yeast retrotransposon Ty can be exploited to produce large amounts of recombinant, particulate fusion proteins as hybrid Ty virus-like particles (Ty-VLPs). This system has now been adapted to allow the release of the additional protein by incorporation of a protease cleavage site between the yeast(More)
BACKGROUND The prevalence and nature of arrhythmias in horses following general anaesthesia and surgery is poorly documented. It has been proposed that horses undergoing emergency surgery for gastrointestinal disorders may be at particular risk of developing arrhythmias. Our primary objective was to determine the prevalence and nature of arrhythmias in(More)
The localization of neutralization determinants within the envelope glycoproteins of human immunodeficiency virus (HIV) has been largely achieved by immunizing small animals in conjunction with Freund's adjuvant. However, for eventual use in humans, candidate HIV vaccine components must also be efficacious in a nontoxic formulation. We describe here the(More)
REASONS FOR PERFORMING STUDY Endotoxaemia is frequently presumed on the basis of clinical signs in horses with colic. OBJECTIVE Measurements of plasma endotoxin (LPS) are rarely made in clinical cases and there is little information on the correlations between this variable, clinical variables and outcomes. OBJECTIVES To measure LPS levels in plasma of(More)
