In a prospective study, we analysed the presence of monoclonal immunoglobulin (moIg) in the serum from 30 patients with amyotrophic lateral sclerosis (ALS) and 30 matched controls using a sensitive Western blot technique. The incidence of serum moIg was 60% in the ALS group and 13.3% in the control group. Most ALS sera contained 2 or 3 monoclonal(More)
Dynamic Cardiomyoplasty. Latissimus dorsi dynamic cardiomyoplasty has been used in our institution for heart failure patients refractory to medical therapy; 113 cases were operated at Broussais and Pompidou Hospitals and 75 patients by our team abroad, in the scope of an international cooperative program. Cardiomyoplasty has been associated with better(More)
The classes, subclasses and light chain types of 78 serum monoclonal immunoglobulins (MoIg) from adult patients affected with various clinical forms of human immunodeficiency virus (HIV) infection were studied by a sensitive Western blot technique. The incidence of MoIg-containing sera was 26% in a systematic study. Most of these sera contained several (up(More)
BACKGROUND Locally delivered angiogenic growth factors and cell implantation have been proposed for patients with myocardial infarcts without a possibility of percutaneous or surgical revascularization. The goal of this study was to compare the effects of these techniques in an experimental model of myocardial infarct. METHODS Left ventricular myocardial(More)
The lectin jacalin from jackfruit seeds shows a human IgA-subclass specificity by gel precipitation and Western blotting. However, its reactivity with IgA2 is a matter of controversy. We further studied the immunoglobulin isotype specificity of jacalin by affinity chromatography with myeloma sera and by inhibition of jacalin binding to solid-phase IgA1 by(More)
1. This study attempts to elucidate unique heart and blood pressure responses seen in sloths in response to tilting by blocking autonomics with atropine, propranolol, or a combination of these. 2. Atropine produces less heart rate increase in sloths than in other mammals but blocks reflex bradycardia as expected. 3. Propranolol reduces heart rate to about(More)
Monoclonal IgG-containing type II cryoglobulins (CG) from 25 patients, most affected with autoimmune or inflammatory diseases, were characterized using a Western blotting procedure. Rheumatoid factors were measured by ELISA. Out of the 25 type II CG, 14 contained a single monoclonal IgG and 11 contained several distinct monoclonal Ig, as assessed by the(More)
While various donor cells have been studied to induce myogenesis after myocardial infarc-tion, recent interest has arisen in promoting cardiac angiogenesis. Angiogenic growth factors (as basic fibroblast growth factor and vascular endothelial growth factor) and genes encoding angiogenic factors are being delivered to the infarcted area to induce growth of(More)
Rheumatoid factors were isolated for immunochemical study by a simple procedure based on immunoadsorption after dissociation of immune complexes. A monoclonal IgA that was not detectable in the patient's unseparated serum was thus demonstrated in one case of hypergammaglobulinemic purpura whereas polyclonal anti-IgG antibodies were isolated in several(More)
