Availability of specific antihuman IgM antibodies is very important for developing diagnostic kits for infectious diseases that are highly prevalent in Indonesia. In line with such idea, an attempt to construct hybridoma cells producing antihuman IgM antibodies is done by fusing NSl myeloma cell line with immunized mouse spleen celLs. Hybridomas producing anti human IgM antibodies have been obt...

BACKGROUND Toxoplasma gondii (T. gondii) infection is one of the most common parasitic infections among humans and other warm-blooded animals worldwide. The aim of this study was to evaluate toxoplasmosis status in patients admitted to Al-Zahra hospital, Isfahan, Iran. METHODS This cross-sectional study was conducted from October 2012 to January 2015. During this period, 716 patients referred...

OBJECTIVES Environmental factors, such as different infections, have proposed to be involved in the pathogenesis of multiple sclerosis (MS). This study aimed to the evaluate mycoplasma pneumonia seropositivity, as a common cause of community-acquired pneumonia in patients with relapsing-remitting multiple sclerosis (RRMS). METHODOLOGY Using ELISA method, IgM and IgG antibodies to Mycoplasma p...

Eighty consecutive adults (age > 12 years) with clinical symptoms, signs and radiological evidence of acute CAP (duration < 4 weeks) presenting to our tertiary care center were enrolled. Clinical symptoms for inclusion were: (i) fever (>100°F) and cough; (ii) any one of the following symptoms chest pain, breathlessness, sputum expectoration, hemoptysis, or wheeze; and (iii) radiological evidenc...

background: the ability of polyclonal antibodies to react with many epitopes of an antigen makes them valuable reagents in research and diagnosis. the aim of this study was purification of mouse igg2a and production of polyclonal antibody against purified mouse igg2a subclass. materials and methods: mouse igg2a was purified by proa affinity. verification method of the purified antibody was sds-...

Spontaneous inhibitors of factor VIII (FVIII) are pathogenic IgG autoantibodies of restricted isotypic heterogeneity found in the plasma of patients presenting with bleeding episodes and low levels of FVIII. We now report the presence of a natural FVIII-neutralizing activity in 85 of 500 plasma samples (17%) from healthy donors. FVIII-inhibitory activity was present in F(ab')2 fragments of puri...

Verification of the efficacy of Biocan B inj. ad us. vet. (Bioveta, a.s.) was done by challenge testing. Ticks collected in the nature were used as natural vectors of the infection. Six beagles and two control ones were used in the test. Formation of outer surface protein A specific antibodies (OspA antibodies) and borrelia specific immonoglobulins (IgG) was measured by Western blot and EIA in ...

Using 6 fractions differing in molecular weight of Dermatophagoides pteronyssinus (Dp)-antigen, we measured by enzyme-linked immunosorbent assay (ELISA) the titers of specific IgE, IgG and IgG4 antibodies against Dp antigen in sera of allergic subjects who were sensitive to house dust mite. We intended to evaluate which Dp fraction acts as the major antigenicity for allergic subjects. Results w...

BACKGROUND Low-density lipoprotein (LDL) can be oxidatively modified by reactive oxygen species, thus generating oxLDL. The latter induce formation of specific antibodies (oxLDLAb), which are detectable in patients with atherosclerosis, in which they might play a pathogenic or a protective role. Thus, we aimed to investigate the association of antibodies with oxidized LDLs (oxLDL) (oxLDLAbs) wi...

BACKGROUND Anxiety is a heterogeneous behavioral domain playing a role in a variety of neuropsychiatric diseases. While anxiety is the cardinal symptom in disorders such as panic disorder, co-morbid anxious behavior can occur in a variety of diseases. Stiff person syndrome (SPS) is a CNS disorder characterized by increased muscle tone and prominent agoraphobia and anxiety. Most patients have hi...
