BACKGROUND Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease caused by immune system-mediated tissue damage. Autoimmune thyroiditis (AT) is an organ-specific disease associated with production of a variety of antibodies such as antinuclear antibodies, anti-double-stranded DNA, anti-Ro antibodies and anti-cardiolipin antibodies. OBJECTIVES The aim of this study was to ev...

BACKGROUND Zoonotic cutaneous leishmaniasis (ZCL) is an increasing public health problem in some endemic regions. Horseradish peroxidase (HRP) conjugated rabbit anti-Rhombomys opimus (R. opimus) Ig is needed for immunoblotting and ELISA tests used to explore the immune response of the rodents against the sand fly saliva. In this study, the production of HRP conjugated rabbit anti-R. opimus Ig w...

Resistance to benznidazole in certain strains of Trypanosoma cruzi may be caused by the increased production of enzymes that act on the oxidative metabolism, such as mitochondrial tryparedoxin peroxidase which catalyses the reduction of peroxides. This work presents cytotoxicity assays performed with ferrocenyl diamine hydrochlorides in six different strains of T. cruzi epimastigote forms (Y, B...

Background: Invariant natural killer cells (iNKT) are an important immunoregulatory T cell subset. Currently several flow cytometry-based approaches exist for the identifi-cation of iNKT cells, which rely on using the 6B11 monoclonal antibody or a combina-tion of anti-Vα24 and anti-Vβ11 antibodies. Objective: The aim of this study was to compare the ability of two flow cytometry-based methods f...

definitive diagnosis of brucellosis is made by isolation of the causative agents, which is a timeconsumingprocedure. to evaluate the efficacy of dot-elisa for detecting brucellae in clinical samples, 94different specimens taken from animal origin were cultured on brucella selective culture media and colonieswere identified biochemically. the specimens were also examined after centrifugation by ...

background: human cd34 is a transmembrane glycoprotein which is expressed in human hematopoietic stem cells (hscs) and the small- vessel endothelial cells of a variety of tissues. cd34 plays a critical role as a marker for diagnosis and classification of leukemia. anti cd34 antibodies are used for isolation and purification of hscs from bone marrow, peripheral blood and cord blood. objective: t...

In a comparative study, the enzyme-linked immunosorbent assay, using peroxidase labeled anti-rat immunoglobulin M and immunoglobulin G, and the passive hemagglutination test were applied to determine the primary and secondary antibody response to lipopolysaccharide and tetanus toxoid in rats. In the enzyme-linked immunosorbent assay, the antigens were bound to the wells of polystyrene microplat...

objectives: clinical laboratory health care workers can become infected through their occupation with blood-borne pathogens by percutanous injuries and mucocutaneous blood contacts such as cuts, needle sticks, splashes to mucous membranes or other body injuries. the purpose of this study was to determine the seroprevalence of, hepatitis c virus (hcv), and some of the risk factors in medical lab...

Genetic factors are thought to be an important determinant of thyroid function and autoimmunity. However, there are limited data on genetic variants in Asians. In this study, we performed a genome-wide association study on plasma thyroid-stimulating hormone (TSH) and free thyroxine (fT4) concentration and anti-thyroid peroxidase (anti-TPO) antibody positivity in 4238 Korean subjects. In the Sta...
