The occurrence of materials cross-reacting with anti-A and -B agglutinins in fruit or seed extracts of higher plants

Journal of Immunogenetics

Fourteen species of higher plants were found to contain materials in their fruit or seed extracts which were heat stable, inhibitory for and capable of absorbing anti-H, -A and -B agglutinins and also lectins. The majority of species exhibiting a high grade of such cross-reactivity belonged to two genera, Viburnum of the Caprifoliaceae and Acer of the Aceraceae. Gel diffusion patterns indicated, however, that the A- and B-like activities of the Viburnum fruits were somewhat distinct serologically from blood group A and B substances of human origin.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
