WebFunctionalized Titanium Nanoparticles Induce Oxidative Stress and Cell Death in Human Skin Cells WebRh disease. Rh disease (also known as rhesus isoimmunization, Rh (D) disease, and blue baby disease) is a type of hemolytic disease of the fetus and newborn (HDFN). HDFN due to anti-D antibodies is the proper and currently used name for this disease as the Rh blood group system actually has more than 50 antigens and not only the D-antigen. Antibodies are produced when the body is exposed to an antigen foreign to the make-up of the body. If a mother is exposed to a foreign antigen and produces IgG (as opposed to IgM which does not cross the placenta), the IgG will target the antigen, if present in the fetus, and may affect it in utero and persist after delivery. The three most common models in which a woman becomes sensitized toward (i.e., produces IgG antibodies against) a particular antigen are hemorrhage, blo… grey wolf youtube

WebAim: 1) We have presented our experiment conducted to detect anti-K antibodies from the Kell-system in pregnant women and their connection with potential destruction of foetal red cells, which may result in haemolytic disease of the foetus and the newborn (HDFN). 2) We have also indicated serological and molecular methods important for a proper diagnosis. WebHDN occurs when the immune system of the mother sees a baby's RBCs as foreign. Antibodies then develop against the baby's RBCs. These antibodies attack the RBCs in the baby's blood and cause them to break down too early. HDN may develop when a mother and her unborn baby have different blood types.
