PROBLEM Antiphospholipid antibodies (APAs) are important in the etiology of reproductive failure. Studies have shown that binding proteins are necessary for the detection of APAs. One of these, beta 2-glycoprotein, has been shown to be necessary for detection of anticardiolipin antibodies. It is felt that some APAs may be directed to the binding protein itself, or to a combination of the bindin...

different classes of autoantibodies against two antigenic forms of modified low density lipoprotein (mod-ldl) were detected in 140 patients by indirect elisa method. investigated autoantibodes included total immunoglobulins (igt). immunoglobulin g (igg), and immunoglobulin m (igm) against oxidized ldl with copper ions (ox-ldl) and modified ldl with malondialdehyde (mal-ldl) (igt-o) igt against ...

background: tonsils and adenoids are involved in both local immunity and immune surveillance for the development of immune defense mechanisms. a number of investigators have found decreased immunoglobulin levels after adenotonsillectomy while others have failed to find significant changes. the effects of adenotonsillectomy on the cellular immunity of children have not been investigated extensiv...

Objetivos: Evaluar prueba inmunocromatográfica para detección de anticuerpos IgM e IgG contra el SARS-CoV-2, usando referencia ELISA IgM/IgG COVID-19. Metodología: El estudio realizado comparó inmunocromatográficas con IgM/IgG. También se efectuó estimación sensibilidad y espe...

Objective: Determine the frequency of rheumatoid factor (IgM-RF) and anti-cyclic citrullinated peptide antibodies (anti-CCP), antinuclear antibodies (ANA), antineutrophil cytoplasmic antibodies (ANCA), anticardiolipin antibodies (aCL), and anti-β2 glycoprotein I antibodies (anti-β2GPI) in leprosy patients, with and without joint involvement, and to evaluate the possible association among those ...

The dissemination of the dengue virus (DENV) in endemic regions with HIV is a public health concern greater importance when there evidence vertical transmission DENV during pregnancy.
