background: cesarean section delivery can lead to much maternal morbidity. different cytokines have been reported to be influenced by the mode of delivery. objective: to investigate the influence of mode of delivery on maternal, placental and cord sera of interferon gamma (ifn-γ), interleukin-4 (il-4) and interleukin-10 (il-10) levels. methods: these three cytokines were measured using elisa in...

Canine immunoglobulin G complexed with particulate or soluble antigen can bind to the Fc receptors on the mastocytoma cells. Attachment of immune complexes composed of immunoglobulin G and soluble antigen (ovalbumin) to mastocytoma cells was detected by an inhibition of rosette formation with indicator cells (sensitized sheep erythrocytes). Therefore, canine circulating immune complexes may als...

Four patients allergic to many mammalian sera were found to have circulating, skin-sensitizing antibodies for these sera. A study of these antibodies by in vitro neutralization and subsequent local passive transfer showed that, in the case of each patient, one particular mammalian serum neutralized antibodies for all sera whereas other mammalian sera neutralized antibodies for themselves alone ...

Organoklorlu Pestisit(OCP)’ler doğada kalıcı özelliktedir ve toprakta birikme eğilimi gösterir. Çevreye insan sağlığına olan olumsuz etkilerinden dolayı son yıllarda dikkat çekmeye başlamıştır. OCP’lerin besin zincirine katıldığı ilk nokta sera yetiştiriciliğinde, seviyelerinin tespit edilmesi derece önem arz etmektedir. Bu çalışmada 24 Plastik, cam kaplı serada OCP seviyeleri ölçülmüş sahipler...

In this study, a localized surface plasmon resonance (LSPR) nanobiosensor was designed to quantify anti-Brucella antibodies in the human sera. Smooth Lipopolysaccharide (LPS) extracted from Brucella melitensis via modified hot phenol water method and fixed on of gold nanoparticles by covalent interactions with functionalized nanoparticles. To obtain best performance probe, ratio LPS nanoparticl...

Smooth lipopolysaccharides (SLPS) from Brucella abortus contain A-epitopes against which the majority of serum antibodies are directed during infections. SLPS from Yersinia enterocolitica 0:9 possesses identical epitopes, which are the cause for serological cross-reactivity. All Brucella spp. possess M- and C-epitopes which are not present in Y. enterocolitica 0:9. In order to examine the usefu...

Growth hormone and thyroid hormones have been implicated as important serum factors for adipocyte development in cell culture. Fetal decapitation removes these factors from serum of the growing fetal pig and results in development of fewer adipocytes than in intact fetuses. These experiments examined the effects of growth hormone or thyroxine supplementation to decapitated fetal pig sera upon p...

There are conflicting reports on the effect of serum from patients with insulin-dependent diabetes mellitus (IDDM) or normal human serum on beta-cell function and insulin secretion. Here, we report that the sera of newly diagnosed IDDM patients potently suppresses insulin secretion from a clonal rat pancreatic beta-cell line (BRIN-BD11), but do not alter cell viability. Indeed, the viability of...

since the incidence of symptomatic congenital cytomegalovirus infection is low (~0.05%) and risk factors are not well defined, it is difficult to develop strategies for prevention. the aim of this study was to recognise the utility of specific immunoglobulin g avidity analysis for distinguishing primary infection from past/recurrent infection. sera from 50 women with cytomegalovirus specific im...
