Acrylamide and glycidamide: approach towards risk assessment based on biomarker guided dosimetry of genotoxic/mutagenic effects in human blood.

Acrylamide (AA) is a carcinogen as demonstrated in animal experiments, but the relevance for the human situation is still unclear. AA and its metabolite glycidamide (GA) react with nucleophilic regions in biomolecules. However, whereas AA and GA react with proteins, DNA adducts are exclusively formed by GA under conditions simulating in vivo situations.

Acrylamide and glycidamide: genotoxic effects in V79-cells and human blood.

Acrylamide (AA) can be formed in certain foods by heating, predominantly from the precursor asparagine. It is a carcinogen in animal experiments, but the relevance of dietary exposure for humans is still under debate. There is substantial evidence that glycidamide (GA), metabolically formed from AA by Cyp 2E1-mediated epoxidation, acts as ultimate mutagenic agent.

Mycophenolate mofetil for the treatment of acute and chronic GVHD in bone marrow transplant patients.

The efficacy and safety of mycophenolate mofetil (MMF) in combination with CsA and prednisolone for the treatment of acute and chronic GVHD (aGVHD and cGVHD, respectively) after BMT and PBSCT from HLA-mismatched and -matched donors was evaluated in an open single center trial. Twenty-four patients, 17-48 years of age, with acute (n = 17) and chronic GVHD (n = 7) were treated with 2 g MMF daily in addition to CsA and prednisolone. Overall grade improvement of aGVHD was found in 11 of 17 (65%) patients treated with MMF.

A second unrelated bone marrow transplant with an unrelated donor marrow: treatment of a patient with relapsed leukemia.

A second bone marrow transplant might be considered as an option in patients with leukemia relapsing after bone marrow transplantation. We report the successful treatment of a patient with relapsed ALL with a second BMT from the same unrelated donor. We evaluated the usefulness of an unrelated donor as the source of the second BMT in this clinical setting.
