PCR amplicons enlarged by approximately 250bp were generated from the 16S rRNA (rrs) genes of certain strains of the recently described Helicobacter species, H. canis. The DNA sequence of the rrs gene of one such strain was determined, and it was shown that an intervening sequence (IVS) of 235bp followed nucleotide 199 in the rrs sequence. In four other H. canis strains, identical or similar IV...

The locations, projections, and functions of the intracardiac ganglia are incompletely understood. Immunocytochemical labeling with the general neuronal marker protein gene product 9.5 (PGP 9.5) was used to determine the distribution of intracardiac neurons throughout the cat atria and ventricles. Fluorescence microscopy was used to determine the number of neurons within these ganglia. There ar...

AIM To study the biocompatibility of surgical meshes for use in pelvic reconstructive surgery using an animal model. METHODS Eight different types of mesh: Atrium, Dexon, Gynemesh, IVS tape, Prolene, SPARC tape, TVT tape and Vypro II, were implanted into the abdominal walls of rats for 3 months' duration. Explanted meshes were assessed, using light microscopy, for parameters of rejection and ...

Lipoprotein-a [Lp(a)], one of the most atherogenic lipoproteins, is composed of a low-density lipoprotein (LDL) core in addition to an apo-a of variable size which is linked to apoB by a disulphide bridge. Lp(a) synthesized in vitro by incubation of recombinant apo-a (r-apo-a) with LDL is physico-chemically indistinguishable from native Lp(a). The synthesis of Lp(a) in vitro proceeds in two ste...

The genomic analysis of a 70-year-old man with recurrent deep venous thrombosis having a protein S (PS)-deficient phenotype corresponding to both type III and type II evidenced two different mutations: a +5 g-->a mutation in the donor splice site of intron e (ivs e) and a ser 460 to Pro mutation. The propositus' son, who had a type II PS deficiency phenotype, only bore the ivs e +5 g-->a mutati...

The genome of the obligate intracellular pathogen Coxiella burnetii contains a large number of mobile genetic elements including two group I introns and an intervening sequence (IVS) that interrupt the 23S rRNA gene; an intein within dnaB (encoding replicative DNA helicase) and a homing endonuclease. The introns are self-splicing ribozymes and able to inhibit ribosome function and retard bacter...

BACKGROUND Pacing has been proposed as a treatment for patients with hypertrophic obstructive cardiomyopathy (HOCM), but there are few studies with long-term follow-up. We evaluated the long-term effects of dual-chamber pacing therapy for patients with HOCM, and to identify the most prognosis-specific factors for predicting outcome in such treating methods. METHODS A total of 37 HOCM patients...

Both left ventricular (LV) hypertrophy and insulin resistance (IR) have often been demonstrated in patients with essential hypertension (EH). Insulin may exert a direct growth promoting effect on cardiomyocytes rather than affecting the LV internal diameter. The purpose of this study was to examine the effect of IR on LV geometry. We enrolled 105 patients (71 females, mean age, 49.2 +/- 13.6 ye...

In this study we have characterised by oligonucleotide hybridisation and direct restriction endonuclease analysis the beta thalassaemia mutation in 494 Sardinian beta thalassaemia heterozygotes. The most prevalent mutation, accounting for 95.4% of the cases, was the nonsense mutation at codon 39. The remainder, in decreasing order of frequency, were a frameshift at codon 6 (2.2%), beta + IVS-1,...
