88 patients with drug addition were evaluated for hbsag, hbeag, anti-hbc, anti hiv syphlisis and anti-toxoplasma antibodies. 48 of them were male and 40 were female. the range of their ages was between 19 to 49 years and their addiction time were between 6 month to 30 years. the results show that 5.6% of the patients have hbsag in their blood serum and 40.9% of them have anti-hbe antibodies. al...

Serum and nasal wash specimens from 13 human volunteers undergoing experimental secondary infection with influenza A/Peking/2/79 (H3N2) wild-type virus were examined for the molecular form and subclass distribution of immunoglobulin A (IgA) antibodies to the viral hemagglutinin (HA). Nasal IgA antibodies were polymeric and did not bind radiolabeled secretory component, indicating that they were...

background: anti-hla-antibodies are known to affect the allograft survival in transplant recipient patients. objective: the aim of this study was to evaluate the association between anti-hla antibodies and kidney allograft outcomes, particularly in recipients with concur-rent donor bone marrow cell infusion (dbmi). methods: between june 2006 and may 2007, forty living unrelated donor kidney tra...

Aim . To determine the presence or absence of specific IgG antibodies against SARS-CoV-2 antigens in outpatient clinic staff and to compare clinical immunological features from April August 2020. Materials Methods The control group comprised 386 employees Novosibirsk City Clinical Polyclinic №13.The determination blood serum was performed by using ELISA method. A real time method reverse transc...

background and purpose: multiple sclerosis (ms) is believed to be an immune-mediated disorder that develops from an interaction of the individual's genetic and as yet unidentified environmental causes. the prevalence of auto-antibodies in multiple sclerosis patients and their clinical associations vary in various studies. the aim of this study was to determine serum auto antibodies in multiple ...

Pleuritic exudates from patients with lobar pneumonia may be sterile or infected. Sterile fluids, at or about the time of crisis, contain actively acquired antibodies similar to those in the blood serum. Infected fluids do not contain such antibodies, presumably because of the presence in them of large amounts of soluble specific substance. Sterile fluids from patients treated with immune sera ...

Background: It is unclear how IL-35 contributes to chronic hepatitis C virus (HCV) infection. Objective: To evaluate the association of with viral load in HCV infections. Methods: Fifty patients were included, and their age sex matched 50 healthy subjects. Seven ml venous blood was obtained tested for anti-HCV antibodies using ELISA kit, quantitative measurement RNA by PCR, estimation serum lev...

An optical biosensor for proteomic breast cancer biomarker detection in complex media is presented. Bloch Surface Waves (BSW) excited onto one dimensional photonic crystal (1DPC) were used to probe the interaction of HER2 with three antibody species and an inert protein (Bovine Serum Albumin - BSA). The system combines Label-Free readings track bioassay real-time development Fluorescence emissi...

A study was made of the origin, occurrence, and properties of natural antibodies to Gram-negative bacteria in the normal serum of several species. Antibody was measured by a procedure based on the bactericidal reaction carried out under conditions in which activity was a function of the amount of antibody contributed by the test serum. Antibody to seven genera of the family Enterobacteriaceae w...
