PURPOSE We will test the hypothesis that ultrasound supported by polymerase chain reaction (PCR) could improve bacterial identification in non-infected prosthetic joint loosening. The aim was to detect bacterial species in non-infected prosthetic joint loosening using ultrasound and 16S rRNA gene sequencing. METHODS A total of 16 patients (11 women and(More)
Osteogenesis imperfecta (OI) is a bone dysplasia caused by mutations in the COL1A1 and COL1A2 genes. Although the condition has been intensely studied for over 25 years and recently over 800 novel mutations have been published, the relation between the location of mutations and clinical manifestation is poorly understood. Here we report missense mutations(More)
BACKGROUND AND PURPOSE Proton magnetic resonance spectroscopy ((1)H-MRS) is one of the imaging techniques that could be potentially useful for identification of patients with mild cognitive impairment (MCI) who are at increased risk of developing dementia. The aim of the study was to investigate if there is a difference in brain metabolism between stable(More)
Atrial septal defect (ASD) is an incomplete septation of atria in human heart causing circulatory problems. Its frequency is estimated at one per 10 000. Actions of numerous genes have been linked to heart development. However, no single gene defect causing ASD has yet been identified. Incomplete heart septation similar to ASD was reported in transgenic(More)
Procollagen C-endopeptidase (BMP-1) and N-endopeptidase (ADAMTS-2) are key enzymes for correct and efficient conversion of fibrillar procollagens to their self assembling monomers. Thus, they have an essential role in building and controlling the quality of extracellular matrices (ECMs). Here, we tested inhibition of activity of the largest variant of(More)
The aim of the study was the evaluation of frequency and titre of IgA ASCA and IgG ASCA and p-ANCA, c-ANCA in children with IBD and occurrence of ASCA antibodies in relation to coexistence of FA. Patients and methods. The study comprised 95 children at the ages of 2 to 18 years. The diagnosis of IBD was established on the basis of Porto criteria. Tests of(More)
THE AIM OF THE STUDY Was evaluation of the incidence of parenteral symptoms and complications in children with inflammatory bowel disease and their analysis in relation to the examined mutations of CARD15 gene. PATIENTS AND METHODS The study involved 38 children with Crohn's disease, aged from 5 to18 years (median14) and 40 children with ulcerative(More)
Procollagen C-endopeptidase (BMP-1) is one of two key enzymes crucial for conversion of fibrillar procollagens to self-assembling collagen monomers. Recently, we have reported inhibition of the largest variant of BMP-1, a recombinant mammalian tolloid (mTld) in vitro, on procollagen type I using peptides with amino acid sequences in chordin conserved across(More)
BACKGROUND This prospective study investigated the role of mechanical and biological factors in aseptic implant loosening or presumed silent prosthetic joint infection (PJI). METHODS Thirty-seven patients were investigated. Microbiologic and molecular methods were used to detect bacteria on the surface of the failed implants removed during revision(More)
UNLABELLED Leiomyoma uteri is a monoclonal tumour of the uterus muscle layer. It is characterized by excessive, abnormal growth of extracellular matrix. The collagen types I and III are the major components of extracellular matrix. Removal of the C-propeptides in procollagens type I, II, and III by procollagen C-endopeptidase leads to spontaneous(More)
