The soul is divided into a rational part and an irrational part. The rational part can be further divided into a contemplative part, which studies the invariable truths of science and mathematics, and a calculative part, which deals with the practical matters of human life.
Immunoglobulin A (IgA, also referred to as sIgA) is an antibody that plays a critical role in mucosal immunity.More IgA is produced in mucosal linings than all other types of antibody combined; between three and five grams are secreted into the intestinal lumen each day.This accumulates up to 15% of the total immunoglobulin produced in the entire body.he high prevalence of IgA in mucosal areas is a result of a cooperation between plasma cells that produce polymeric IgA (pIgA), and mucosal epithelial cells that express an immunoglobulin receptor called the polymeric Ig receptor (pIgR).
Background. Idiopathic immunoglobulin A (IgA) nephropathy, or Berger disease, is a worldwide primary glomerulonephritis first described by Berger and Hinglais in 1968, based on the finding of predominant IgA deposition in the mesangium with a mesangial proliferation.ackground.
