The objective of the present study was to monitor the occurrence and distribution of a spectrum of trichothecene toxins in different parts of maize plants. Therefore maize plants were sampled randomly from 13 fields in southwest Germany and the fractions kernels, cobs, husks, stalks, leaves and rudimentary ears were analyzed for eight A-type and five B-type(More)
A total of 220 samples comprising cereals, cereal byproducts, corn plants and corn silage as well as non-grain based feedstuffs was randomly collected during 2000 and 2001 from sources located in Germany and analysed for 16 Fusarium toxins. The trichothecenes scirpentriol (SCIRP), 15-monoacetoxyscirpenol (MAS), diacetoxyscirpenol (DAS), T-2 tetraol, T-2(More)
Hemophagocytic lymphohistiocytosis is a rare and fatal disorder of early infancy, which affects predominantly the mononuclear phagocyte system and is characterized by the presence of fever, hepatosplenomegaly and cytopenia. Neurological symptoms can be extremely variable, ranging from irritability, and convulsions to focal neurological signs. They often(More)
Monoclonal antibody (mAb) products are extraordinarily heterogeneous due to the presence of a variety of enzymatic and chemical modifications, such as deamidation, isomerization, oxidation, glycosylation, glycation, and terminal cyclization. The modifications in different domains of the antibody molecule can result in different biological consequences.(More)
Scirpentriol and its seven acetylated derivatives comprise a family of type-A trichothecene toxins produced by several species of Fusarium fungi. Out of this group 4,15-diacetoxyscirpenol has attracted most attention. It elicits toxic responses in several species and was detected in a variety of substrates. Out of the three possible monoacetylated(More)
We report a case of subcutaneous phaeohyphomycosis observed in a male patient presenting pulmonary sarcoidosis and submitted to corticosteroid treatment. He presented nodular erythematous-violaceous skin lesions in the dorsum of the right hand. Histopathological examination of the biopsied lesion revealed dematiaceous hyphae and yeast-like cells, with a(More)
We present a case of subcutaneous hyalohyphomycosis due to Acremonium recifei, a species whose habitat is probably the soil, first identified in 1934 by Arêa Leão and Lobo in a case of podal eumycetoma with white-yellowish grains and initially named Cephalosporium recifei. A white immunocompetent female patient from the state of Bahia, Brazil, with a(More)
A sensitive and selective method for the simultaneous determination of a spectrum of trichothecenes in residuals of biogas production has been developed. It comprises sample clean-up by liquid/liquid partition for digested manure and solid phase extraction for digested solid phase. Quantification of A- and B-type trichothecenes as their trifluoroacetyl(More)
Mass spectrometry (MS) characterization of recombinant monoclonal antibody (mAb) drugs and their degraded and/or post-translationally modified counterparts, drug-product-related impurities and variants, is critical for successful development of biotherapeutics. Specifically in this study, drug-product-related impurities of an anti-Clostridium difficile IgG1(More)
A case of rhinofacial zygomycosis with of years duration, caused by Conidiobolus coronatus is described. The patient, a 72-years-old woman, presented with a bilateral distortion of the subcutaneous tissue and disfigurement of the face. Treatment with ketoconazole and potassium iodide did not prevent several relapses. At present she is still under treatment(More)
