Correlation of anti-cytoskeleton antibody activities in synovial fluid with interleukin-6 in patients with osteoarthritis and inflammatory joint dise…

1990

Synovial fluids and sera from patients with rheumatoid arthritis, psoriatic arthritis, yersinia arthritis, Behçet's syndrome, Crohn's disease, and osteoarthritis were tested for antinuclear antibodies and antibodies to five cytoskeletal components in sensitive enzyme-linked immunosorbent assay (ELISA) systems and for IL-6 concentrations in a proliferation assay (IL-6 dependent hybridoma cell line B13.29, subclone B9). Statistically significant correlations between antibody activities and IL-6 levels were found for vimentin antibodies (r = 0.56; p less than 0.05) and actin antibodies (r = 0.44; p less than 0.05). In patients with chronic and active disease like rheumatoid arthritis and psori…

Cellular Immunity and Retrobulbar Fibroblasts in Graves' Ophthalmopathy

1994

In Graves' ophthalmopathy (GO), retrobulbar connective tissue is infiltrated by T cells whose role in the pathogenesis of the disease was investigated in the present work. The aims included firstly to characterize subsets of blood lymphocytes and of sessile lymphocytes cloned from a retroorbital tissue specimen. Second, in counterstimulation assays, the ability of patients' T cells to influence cultivated retrobulbar fibroblasts and in turn the enhancement of lymphocyte proliferation by retrobulbar fibroblasts was investigated. Blood lymphocytes of 16 GO patients and 12 controls isolated by density gradient centrifugation and retrobulbar fibroblasts obtained from orbital decompression were …

Overexpression of human homologs of the bacterial DnaJ chaperone in the synovial tissue of patients with rheumatoid arthritis

1999

Objective To study the expression of the chaperone family of J proteins in the synovial tissue of patients with rheumatoid arthritis (RA) or osteoarthritis. Methods Rabbit antibodies specific for a synthetic peptide (pHSJ1: EAYEVLSDKHKREIYD), representing the most conserved part of all J domains thus far identified—among them the Drosophila tumor suppressor Tid56—were used in immunohistochemical analyses of frozen sections of synovial tissue and immunoblotting of protein extracts of adherent synovial cells. IgG specific for Tid56 was also used. Results Both antisera predominantly and intensely stained synovial lining cells from RA patients; other cells did not stain or stained only faintly.…

IgA anti-actin antibodies ELISA in coeliac disease: A multicentre study.

2007

Previous studies have demonstrated that serum anti-actin antibodies are a reliable marker of intestinal damage severity in coeliac disease.To validate in a multicentre study the clinical usefulness of serum IgA anti-actin antibody ELISA and its possible use in monitoring intestinal mucosa lesions during gluten-free diet.Four centres recruited 205 newly diagnosed coeliac disease patients with villous atrophy, 80 healthy controls and 81 "disease" controls. Twelve coeliac disease patients on gluten-free diet but with persistent symptoms underwent serum IgA anti-actin antibody assay and intestinal histology evaluation. IgA anti-actin antibody ELISA was performed with a commercial kit. All coeli…

Self-persuasion on Facebook increases alcohol risk perception

2018

Contains fulltext : 198083.pdf (Publisher’s version ) (Closed access) In this experiment, we examined if participating in a Facebook group by generating antialcohol arguments (self-persuasion) is more effective than reading antialcohol posts of others (direct persuasion) in changing alcohol consumption, risk perception, and attitudes. In addition, it was examined if submitting posts moderated these effects. Participants logged into their Facebook account and joined a group that contained posts with antialcohol arguments. They either generated their own arguments with or without posting them, or read those present in the group with or without posting that they had read them. Next, participan…

Identification of a peptide mimicking the binding pattern of an antiphospholipid antibody

2006

Our objective was to characterize monoclonal antiphospholipid antibodies (APL) and identify disease-associated antigens in patients with the antiphospholipid syndrome (APS). We used the monoclonal antibody HL-5B, derived from a patient with APS suffering from multiple ischemic events, to screen a 12-mer peptide phage display library (New England Biolabs, London, England). The identified phage clones were sequenced and the derived consensus peptide was synthesized. The peptide was used to perform competitive inhibition experiments for their ability to inhibit the binding of the monoclonal antibody and of serum antibodies to cardiolipin and phosphatidylserine. Additionally patients and contro…

Accuracy of two plasma antibody tests and faecal antigen test for non-invasive detection of H. pylori in middle-aged Caucasian general population sam…

2018

The aim of the study was to assess the accuracy of two plasma Helicobacter pylori (H. pylori) antibody test-systems and a stool antigen test (SAT) system in a general population sample in Latvia.Blood and faecal samples were analysed in healthy individuals (40-64 years), referred for upper gastrointestinal endoscopy according to pilot study protocol within a population-based study investigating gastric cancer prevention strategies (GISTAR pilot study). Antibodies to H. pylori were assessed in plasma by latex-agglutination test and enzyme-linked immunosorbent assay (ELISA). H. pylori antigen in faecal samples was detected by a monoclonal enzyme immunoassay-based SAT. Histological assessment …

Lexical decision tasks in depressive patients: semantic priming before and after clinical improvement.

2002

SummaryThis study was designed to evaluate the effect of semantic priming with a lexical decision task in 22 depressed patients (DSM-III-R, 1987) and 30 control subjects. These patients were evaluated twice: first when they arrived at the hospital, and secondly, after clinical improvement. Clinical improvement was evaluated using standard depression rating scales. A lexical decision task involving semantic relations (related vs. unrelated, e.g., apple-pear) was used to evaluate the processing of semantic information. The results showed that, for the first evaluation, the depressives presented similar semantic priming to control subjects. When we compared semantic priming in the first and th…

HLA Class I and Class II Polymorphism in Three Sicilian Populations

2007

Two human leukocyte antigen (HLA) class I loci (HLA-A and HLA-B) and one class II locus (HLA-DR) were typed at the DNA level in the Sicilian population. Study participants were of Sicilian origin (183 for class I loci and 260 for class II loci) and live in three towns, chosen on the basis of geographic position and different historical events. These towns are Sciacca (southwest Sicily, located at sea level, conquered by Arabs in a.d. 814), Piana degli Albanesi (northwest Sicily, 720 m above sea level, has maintained religious, cultural, and linguistic peculiarities traced to Albanian settlement in 1488), and Troina (northeast Sicily, 1,120 m above sea level, known as the first settlement of…
