Hypoechoic focus at the uterine fondus. I am glad I found this forum. Anyway I had serious period pains in the last 3 months, this month was fine though. As a result of the previous pain, and our inability to have concieved (Partly male factor-low motility), I decided to have a pelvic and full abdomen scan. Results- There is a 1.3cm vaguely defined hypoechoic focus at the uterine fondus which may represent a fibroid. Please what does this mean?
B-lymphocyte antigen CD19 also known as CD19 (C luster of D ifferentiation 19), is a protein that in humans is encoded by the CD19 gene.It is found on the surface of B-cells, a type of white blood cell.s on T cells, several surface molecules form the antigen receptor and form a complex on B lymphocytes. The (almost) B cell-specific CD19 phosphoglycoprotein is one of these molecules. The others are CD21 and CD81.
Abstract. The human CD19 antigen is a 95 kd transmembrane glycoprotein belonging to the immunoglobulin superfamily. CD19 is classified as a type I transmembrane protein, with a single transmembrane domain, a cytoplasmic C-terminus, and extracellular N-terminus.CD19 is a biomarker for normal and neoplastic B cells, as well as follicular dendritic cells.D19 was first identified as the B4 antigen of human B lymphocytes through the use of anti-B4 monoclonal antibody (mAb) against CD19. It is specifically expressed in normal and neoplastic B cells, as well as follicular dendritic cells [ 9, 11, 15 ].
