In systemic sclerosis (SSc) and idiopathic inflammatory myopathies (IIM), auto-antibodies are used in daily practice as potent biomarkers of clinical phenotypes. This study aimed at estimating the prevalence myositis-specific (MSA) myositis-associated (MAA) a well-characterised SSc patients cohort using two different immunoblot assays, studying their associations.In this cross-sectional study, ...

BACKGROUND Arterial allografts are used as vascular conduits in the treatment of prosthetic graft infection. Immunosuppression decreases their rupture risk rate. However, immunosuppression can be unprofitable in florid infection. Previously, we confirmed inhibition of cell-mediated destruction of rat aortic grafts by delayed use of tacrolimus. In this work, we studied the influence of this prot...

Authors’ address: V. Kondi and Natalia Mitrica, Centre of Haematology, Bucarest (Rumania) In a previous study, we have shown that sera with anti-platelet antibodies from thrombocytopenic patients or those having received multiple blood transfusions – females alloimmunized by pregnancy – are able to induce inhibition of platelet aggregation [2]. The present investigation is designed to study the...

background: in spite of available, and sensitive screening assay for detection of hepatitis b virus surface antigen (hbsag), occasional cases of post-transfusion hepatitis b virus infection are still observed. the aim of the present study was to assess the prevalence of positive anti hepatitis b core (anti-hbc) and presence of hbv-dna in serum sample of healthy blood donors negative for both hb...

Anti-ganglioside (anti-GM1) antibodies have been implicated in the pathogenesis of Guillain-Barré syndrome, multifocal motor neuropathy and motor neuron diseases. It has been held that they may interfere with saltatory conduction by blocking sodium channels. We tested this hypothesis by analysing action potentials from 140 single nerve fibres in 22 rat ventral roots using external longitudinal ...

In this study, IgG fractions from sera of SLE patients with anti-Ro/SSA or anti-Ro/SSA and anti-La/SSB activity were tested in Langendorff preparations of adult rabbit hearts, aiming to reproduce the cardiac manifestations observed in neonatal lupus in an experimental model. The hearts were perfused with normal Tyrode's solution for 30 min, followed by perfusion with Tyrode's containing 0.3 mg/...

IgG3 type. The hematic and serous blood group was identified as 0 Rh positive; anti-DNA and ANA antibodies were negative. Viral serology demonstrated IgM anti-varicella antibodies, anti-HIV, CMV, infectious mononucleosis and hepatitis serelogy was negative. An immunohematological study carried out at the regional transfusion center showed the 3+/4+ positivity for the direct Coombs’ test with th...

conclusions hemodialysis patients are high risk group for toxoplasmosis and should be tested periodically to prevent the dissemination of toxoplasmosis during dialysis. objectives the aim of this study was to determinate the anti- toxoplasma antibodies in hemodialysis patients of abadan and khoramshahr, southwest of iran. materials and methods sera of 150 patients (test group) aged 21 to 87 yea...

Antibody reactivity against survivin, a recently identified tumor-associated protein, was determined in sera from patients with lung (n = 51) or colorectal cancer (n = 49). The same collection of sera was tested for the presence of antibodies against p53. Eleven sera from lung cancer patients and four sera from colorectal cancer patients reacted with purified recombinant survivin in an ELISA (2...
