Measurement of disease activity in patients with inflammatory bowel disease is difficult. The best available methods are complex and time consuming, but it may be possible to use tumour necrosis factor alpha (TNF alpha) concentration in stool as a marker of disease activity. We measured TNF alpha concentrations in stool samples from normal children, infants(More)
Limb and respiratory muscle (diaphragm) strength and fatiguability have been extensively studied in man and are known to vary with age and sex. However, in contrast to limb muscles and the diaphragm, force and fatiguability characteristics have not been studied in upper airway muscles. This study examines the hypotheses that tongue protrusion strength or(More)
Immune complexes containing human gamma (g)1 or murine g2a antibodies generate secondary effector mechanisms via Fc receptor binding or complement activation, whereas those containing human g4 or murine g1 antibodies generally do not. Therefore, isotype selection of therapeutic antibodies may have important clinical consequences. In a rabbit model of human(More)
Tumour necrosis factor-alpha (TNF alpha) is a major proinflammatory cytokine which appears in the cerebrospinal fluid very early after endotoxin challenge, and is likely to be produced locally. Following in vivo and in vitro challenge with endotoxin, we have demonstrated immunocytochemically and by in situ hybridization that pig and guinea-pig choroid(More)
OBJECTIVE To evaluate if pelvic or hip width predisposed women to developing greater trochanteric pain syndrome (GTPS). DESIGN Prospective case control study. PARTICIPANTS Four groups were included in the study: those gluteal tendon reconstructions (n=31, GTR), those with conservatively managed GTPS (n=29), those with hip osteoarthritis (n=20, OA) and(More)
