Anti-TPO ELISA Kit

Background: Estimate of prevalence of thyroid dysfunction in systemic lupus erythematosus (SLE) patients from India is scarce. The present study evaluated the prevalence of thyroid dysfunction and anti-thyroid peroxidase (TPO) antibodies in SLE patients, and the most prominent clinical features of thyroid dysfunction were noted. Materials and Methods: This descriptive, cross-sectional study involved 100 adult patients diagnosed with SLE at a tertiary teaching hospital, Bengaluru, India. The study excluded patients on medications that are known to cause thyroid dysfunctions, those with a history of thyroidectomy, and those with other systemic autoimmune diseases. Results: Among the 100 recruited patients, 99 were females, and most (47%) belonged to the age group of 20-30 years, the median duration of lupus was 24 months. Thyroid dysfunction was observed in 42% (n = 42), and hypothyroidism was the most common thyroid abnormality. None of the patients had hyperthyroidism. Among the patients with thyroid dysfunction, the corresponding number of patients with clinical hypothyroidism and subclinical hypothyroidism were 71% (n = 30) and 29% (n = 12). Of 25 patients with elevated anti-TPO, 48% (n = 12) had clinical hypothyroidism, 20% (n = 5) had subclinical hypothyroidism, and 32% (n = 8) had normal thyroid-stimulating hormone and free T4. Most of the patients with thyroid dysfunction were newly diagnosed, and the predominant symptoms noted were fatigue (75%), hair loss (75%), and joint pain (63%). Conclusions: The prevalence of thyroid dysfunction was found to be higher in SLE than previously published cohorts in India and the rest of the world. It does not affect lupus activity.

In this research, a group of xY(2)O(3)-Ni/MgO-MCM-41 catalysts were synthesized by using direct synthesis method for CO2 hydrogenation and were characterized by employing BET, XRD, HRTEM, XPS, TPD, FE-SEM and TPO to understand the mechanism of CO2 hydrogenation over yttria-Ni/MgO-MCM-41. Compared to Ni/MgO-MCM-41, all catalysts which contained Yttria showed improved catalytic activity. The one with 2 wt% yttria had the highest catalytic performance, with carbon dioxide conversion and methane selectivity of 65.55% and 84.44% at 673 K, respectively, and high stability after 30 h. The impact of adding yttria, as a promoter, on nickel dispersion and that of enhancing carbon dioxide adsorption sites on basicity sites attracted more attention as effective factors regarding conversion, selectivity, and stability.
