Small iontophoretic ejections of horseradish peroxidase (HRP) were made from recording-multibarrel micropipette assemblies in areas of the cat's suprageniculate nucleus (SGn) that contained visually responsive neurones. The sources of afferents of the SGn were determined by locating the labeled cell bodies of neurones that were presumed to send their axons(More)
Fourteen patients with Helicobacter pylori infection were treated with omeprazole capsules 20 mg and amoxycillin capsules 1000 mg twice daily for 14 days and 14 patients with omeprazole capsules 20 mg and placebo twice daily for 14 days. Samples from saliva, dental plaque and faeces and biopsies from antrum and corpus were analysed in order to determine the(More)
Few synaptic transmitters are known to exist that are not represented in some region or another, or at some layer or other, in the cerebral cortex of mammalian brain. The more difficult job than mere identification of which substances are present, is that of the assignment of particular functional role(s) of such substances, and as well, of determining upon(More)
Routine coronary angiographic assessment of bypass graft patency does not allow quantification of bypass graft flow reserve. This study was designed to evaluate the use of cine-computed tomography (cine-CT) to determine relative bypass graft flow velocities and flow reserve. Saphenous vein grafts from the left innominate to the midleft circumflex coronary(More)
Linkage analyses in generalized recessive dystrophic epidermolysis bullosa (RDEB) have implicated the type VII collagen gene (COL7A1), which encodes the major component of anchoring fibrils, and recent identification of COL7A1 mutations has provided direct evidence for COL7A1 defects underlying RDEB. In this study, COL7A1 gene analysis was used to(More)
Forty-four healthy volunteers were given either amoxycillin (ten subjects), cefpodoxime proxetil (ten subjects), ceftibuten (14 subjects) or cefuroxime axetil (ten subjects) orally for 7-10 days, in order to study the ecological effects on the intestinal microflora. In all three groups receiving oral cephalosporins there was a significant increase in(More)
In the present study we determined the resistance patterns of anaerobic bacteria from human saliva and stool specimens and investigated whether there were significant differences in resistance between outpatients and hospitalized patients, regardless of whether they had received antimicrobial agents. No bacterial strains resistant to ampicillin,(More)
