Evaluation of commercial ELISA kits for the screening of deoxynivalenol (DON) was carried out. Three kinds of commercial kits supplied by different companies were used. Three lots of naturally contaminated wheat and DON-free wheat (<0.05 microg/g) were used as samples. The values obtained from ELISA were compared with those of the HPLC-UV method. In the results obtained from 14 institutions using ELISA, the CV values were less than 17.6% for all the commercial kits. The DON-free sample was not detected as positive with any commercial kits. Also there was no negative finding among the naturally contaminated samples used in this experiment. Coefficients of determination in ELISA and HPLC analysis were 0.979-0.999. These results indicate that ELISA using any of the three commercial kits is efficient for the screening of DON in wheat.

Immunogenicity of the CoronaVac vaccine in children: a real-world study.
Front Immunol
December 2024
Grupo Inmunovirología, Facultad de Medicina, Universidad de Antioquia UdeA, Medellín, Colombia.
Background: Despite its proven effectiveness and safety, there are limited real-world data on CoronaVac's immunogenicity in children, especially in lower-income countries, particularly for SARS-CoV-2 variants. We present a real-world study evaluating CoronaVac's immunogenicity in Colombian children stratified by previous exposure to this virus.
Methods: 89 children aged 3-11 years were enrolled (50 Non-Exposed and 39 Exposed).
Background: Multiple sclerosis (MS) is a chronic autoimmune disease damaging the central nervous system. Diminished inflammatory disease activity (DA) as people with MS (pwMS) age motivated randomized clinical trials assessing disease-modifying therapy (DMT) discontinuation in older pwMS given the concern for risks outweighing benefits. This study aims to examine whether peripheral production of Myelin Basic Protein (MBP)-driven cytokine responses mediate the aging-associated decline in MS inflammatory DA.

Wheat is an important cereal crop globally and in the United States, and is the largest crop grown by acreage in Colorado. In June 2023, we observed wheat fields displaying severe yellowing and virus-like disease symptoms in plants across seven eastern Colorado counties (Yuma, Prowers, Kit Carson, Washington, Sedgewick, Morgan, and Weld). Symptomatic plants were prominent in fields and appeared bright yellow, with ringspots, mosaic patterning, and streaking on leaves.

Introduction: Although rituximab is approved for several autoimmune diseases, no formal dose finding studies have been conducted. The amount of CD20+ cells differs significantly between autoimmune diseases and B-cell malignancies. Hence, dose requirements of anti-CD20 therapies may differ accordingly.

Introduction: Though COVID-19 as a public health emergency of international concern (PHEIC) was declared to be ended by the WHO, it continues to pose a significant threat to human society. Vaccination remains one of the most effective methods for preventing COVID-19. While most of the antigenic regions are found in the receptor binding domain (RBD), the N-terminal domain (NTD) of the S protein is another crucial region for inducing neutralizing antibodies (nAbs) against COVID-19.
