Introduction: Aflatoxin M1 is an important mycotoxin frequently found in milk and dairy products. The main objective of this work was to study the stability of AFM1 during production and refrigerated storage of probiotic yogurt. Materials and methods: Two kinds of probiotic yogurt were made by cow’s milk artificially contaminated with aflatoxin M1 at a level of 100 ng/l, and fermented...

(4) Let K be a field and M1, M2, M3 be matrices over K. Suppose lenM1 = lenM2 and lenM2 = lenM3 and widthM1 = widthM2 and widthM2 = widthM3 and lenM1 > 0 and M1 + M3 = M2 +M3. Then M1 = M2. (5) For every field K and for all matrices M1, M2 over K such that lenM2 > 0 holds M1 − −M2 = M1 +M2. (6) For every field K and for all matrices M1, M2 over K such that lenM1 = lenM2 and widthM1 = widthM2 an...

aflatoxin m1 (afm1) is a hydroxylated metabolite of the carcinogen aflatoxin b1 (afb1), and may be found in the milk of lactating animals that have ingested feedstuffs contaminated with afb1 between jun 2010 and march 2011, 149 samples of pasteurized (n=90) and uht (n=59) milk were collected from supermarkets in the cities of shiraz, khuzestan and yazed, iran. all samples were analyzed for afm1...

background and purpose :aflatoxin m1, in milk and dairy products, is classified by the international agency for research on cancer as human carcinogens (class 2b). the aim of this study was to evaluate aflatoxin m1 contamination level in dairy products from iranshahr city, iran, using elisa technique. materials and methods: in our study, 87 samples of milk, white cheese, yoghurt, and butter wer...

OBJECTIVE To compare performance of contemporary aquaporin-4-immunoglobulin (Ig) G assays in clinical service. METHODS Sera from neurologic patients (4 groups) and controls were tested initially by service ELISA (recombinant human aquaporin-4, M1 isoform) and then by cell-based fluorescence assays: fixed (CBA, M1-aquaporin-4, observer-scored) and live (fluorescence-activated cell sorting [FAC...
