Background: Selective antibody deficiency with normal immunoglobulins (SADNI) may be identified as part of distinct primary or secondary immunodeficiency disorders. The clinical manifestations include recurrent, often severe or prolonged, upper or lower respiratory tract infections. Objectives: To evaluate SADNI in patients with recurrent sinopulmonary infections and its relation to IgG subclas...

Magnetic nanoparticles (MNPs) have emerged as a promising material in disease diagnostics due to their potential enhance detection sensitivity, facilitate concentration and purification of target substances diverse samples, enable favorable color-based detection. In this study, antibody-conjugated MNPs were successfully synthesized validated through two appropriate methods: the measurement MNPs...

a new signal amplification strategy based on simultaneous application of gold nanoparticles (aunps) and horseradish peroxidase (hrp) was employed to improve the sensitivity of an electrochemical immunoassay for detection of human igg (higg), as a model antigenic protein. this immunoassay system was fabricated on magnetic carboxyl-functionalized multi-walled carbon nanotubes (cooh-mwcnt/fe3o4 na...

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: ...

Cross-linked dimers of ribonuclease, added at a concentration of 0.05 mg/ml to the culture medium of hepatoma (HTC) cells, were previously shown to inhibit intracellular degradation of peroxidase taken up by endocytosis. Intracellular localization showed that endocytosed peroxidase does not reach lysosomes in dimer-treated cells. The present study shows that preloading of lysosomes with fluores...

Abstract Objectives Laboratory services are an important part of the healthcare system. However many requested tests may be considered inappropriate or unnecessary. We evaluated laboratory use in a period 3 years terms test repeats. Methods analyzed repeat rate (IRR) hemoglobin A1c (HbA1c), 25-OH vitamin D [25(OH)D], thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), thyroxine (FT4...

A new signal amplification strategy based on simultaneous application of gold nanoparticles (AuNPs) and horseradish peroxidase (HRP) was employed to improve the sensitivity of an electrochemical immunoassay for detection of human IgG (hIgG), as a model antigenic protein. This immunoassay system was fabricated on magnetic carboxyl-functionalized multi-walled carbon nanotubes (COOH-MWCNT/Fe3...

Abstract Background Obesity-related oxidation stress plays a key role in obesity complications; however, its relation to thyroid status is an area for further research. The study aimed assess function obese children and oxidative deoxyribonucleic acid (DNA) damage. Results Fifty 40 normal weight were included . Anthropometric measurement, lipid profile, function, anti-thyroglobulin antibody, pe...
