It is recognized that while non-ABO RBC antibodies are less common than ABO antibodies, they generate essentially the same issues that lead to unfavorable clinical results. If non-ABO alloantibodies are identified early on, these issues related complications may be avoided This call for an in-depth understanding of the recipient and donor’s ABO-Rh grouping, antibody screening, and the phenotype of certain antigens. Equally important, the temporal association time between transplantation and hemolysis can help identify the underlying mechanism of hemolysis and direct appropriate management. Therefore, for that, it is crucial to identify the etiology of post-HSCT anemia for prevention and therapy, in addition to a thorough grasp of the mechanism of anemia in non-ABO-incompatible HSCT and the temporal link between HSCT and anemia. Finding the cause of post-HSCT anemia is essential for prevention and therapy, in addition to a thorough grasp of the mechanism of anemia in non-ABO-incompatible HSCT and the temporal link between HSCT and anemia. Therefore, for that, it is crucial to identify the etiology of post-HSCT anemia. In this case report review, we would like to highlight the vital role of transfusion medicine services and stem cell clinical teams in paying particular attention to the clinical significance of non-ABO alloantibodies involved to avoid causing overt hemolysis of incompatible donor RBCs or delayed erythropoiesis. Considering the fact that some of the Haematopoietic stem cell transplant centers do not give an attention to the other non-ABO RBC antigens.展开更多
In this study, total mercury in canned tuna in comparison with Hypophthalmichthys molitrix （fitofag or phytophag） fish samples were determined by flow injection cold vapour generation atomic absorption spectrometry ...In this study, total mercury in canned tuna in comparison with Hypophthalmichthys molitrix （fitofag or phytophag） fish samples were determined by flow injection cold vapour generation atomic absorption spectrometry after digestion by the two different methods. The mercury concentration varied from 83 to 290 ng g~ with an average value of 147 ng g-1 in canned tuna, while the concentration varied from 14 to 56 ng g-1 with an average value of 26 ng g-1 for fitofag fish. Recoveries of the total mercury were in the range of 81-107% and 120-160% by method 1 and 2, respectively. The results of this study indicate that tuna and fitofag fish from the Persian Gulf area of Iran have concentrations well below the permissible FAO/WHO levels for total mercury and also the feed regime of fishes can affect the mercury accommodation. Therefore, their contribution to the body burden can be considering negligible and the fish seem to be safe for human consumption.展开更多
