A 4-hydroxylated metabolite of AFLATOXIN B1, one of the MYCOTOXINS from ASPERGILLUS tainted food. It is associated with LIVER damage and cancer resulting from its P450 activation to the epoxide which alkylates DNA. Toxicity depends on the balance of liver enzymes that activate it (CYTOCHROME P-450) and others that detoxify it (GLUTATHIONE S TRANSFERASE) (Pharmac Ther 50.443 1991). Primates & rat are sensitive while mouse and hamster are tolerant (Canc Res 29.236 1969).
Furano-furano-benzopyrans that are produced by ASPERGILLUS from STERIGMATOCYSTIN. They are structurally related to COUMARINS and easily oxidized to an epoxide form to become ALKYLATING AGENTS. Members of the group include AFLATOXIN B1; aflatoxin B2, aflatoxin G1, aflatoxin G2; AFLATOXIN M1; and aflatoxin M2.
A potent hepatotoxic and hepatocarcinogenic mycotoxin produced by the Aspergillus flavus group of fungi. It is also mutagenic, teratogenic, and causes immunosuppression in animals. It is found as a contaminant in peanuts, cottonseed meal, corn, and other grains. The mycotoxin requires epoxidation to aflatoxin B1 2,3-oxide for activation. Microsomal monooxygenases biotransform the toxin to the less toxic metabolites aflatoxin M1 and Q1.

Toxic effects of mycotoxins in humans. (1/28)

Mycotoxicoses are diseases caused by mycotoxins, i.e. secondary metabolites of moulds. Although they occur more frequently in areas with a hot and humid climate, favourable for the growth of moulds, they can also be found in temperate zones. Exposure to mycotoxins is mostly by ingestion, but also occurs by the dermal and inhalation routes. Mycotoxicoses often remain unrecognized by medical professionals, except when large numbers of people are involved. The present article reviews outbreaks of mycotoxicoses where the mycotoxic etiology of the disease is supported by mycotoxin analysis or identification of mycotoxin-producing fungi. Epidemiological, clinical and histological findings (when available) in outbreaks of mycotoxicoses resulting from exposure to aflatoxins, ergot, trichothecenes, ochratoxins, 3-nitropropionic acid, zearalenone and fumonisins are discussed.  (+info)

Molecular dosimetry of urinary aflatoxin-DNA adducts in people living in Guangxi Autonomous Region, People's Republic of China. (2/28)

Hepatocellular carcinoma is one of the five leading human cancers causing at least 250,000 deaths each year. One of the major risk factors for this disease is exposure to dietary aflatoxins, and the development of appropriate molecular dosimetry biomarkers would facilitate the identification of individuals at risk. This study was undertaken to explore the relationship between dietary intake of aflatoxins and the excretion of the major aflatoxin-DNA adduct and other metabolites into the urine of chronically exposed people. The following protocol was developed for this investigation in Guangxi Autonomous Region, People's Republic of China, where the diets of 30 males and 12 females (ages, 25-64 years) were monitored for 1 week and aflatoxin intake levels determined each day. Starting on the fourth day, total urine volumes were obtained in consecutive 12-h fractions for 3 or 4 days. High performance liquid chromatography and competitive radioimmunoassay analyses were done on each of the urine samples, and the relationships between excretion of total aflatoxin metabolites, aflatoxin-N7-guanine, aflatoxin M1, aflatoxin P1, and aflatoxin B1, and aflatoxin B1 intake values were determined. The average intake of aflatoxin B1 by men was 48.4 micrograms/day, giving a total mean exposure during the study period of 276.8 micrograms. The average daily intake by women was 77.4 micrograms/day, resulting in a total average exposure during the 7-day period of 542.6 micrograms aflatoxin B1. Initial efforts to characterize aflatoxin metabolites in urine samples were with an analysis by competitive radioimmunoassay. The analysis by linear regression of the association between aflatoxin B1 intake/day and total aflatoxin metabolite excretion/day showed a correlation coefficient of only 0.26. These findings stimulated the immunoaffinity/analytical high performance liquid chromatography analysis for individual metabolites. When the data were analyzed by linear regression analysis, the aflatoxin N7-guanine excretion and aflatoxin B1 intake from the previous day showed a correlation coefficient of 0.65 and P less than 0.000001. Similar analysis for aflatoxin M1 resulted in a correlation coefficient of 0.55 and P less than 0.00001, whereas there was no positive statistical association between exposure in the diet and aflatoxin P1 excretion, despite aflatoxin P1 being quantitatively a major metabolite. Analysis of the total aflatoxin-N7-guanine excretion in the urine during the complete collection period plotted against the total aflatoxin B1 exposure in the diet for each of the individuals, smoothing the day to day variations, revealed a correlation coefficient of 0.80 and P less than 0.0000001.(ABSTRACT TRUNCATED AT 400 WORDS)  (+info)

Measurement of aflatoxin and aflatoxin metabolites in urine by liquid chromatography-tandem mass spectrometry. (3/28)

Automated immunoaffinity solid-phase extraction followed by liquid chromatography-tandem mass spectrometry and chemical analogue internal standardization is employed to detect and quantify the aflatoxins AFB(1), AFB(2), AFG(1), AFG(2), and the metabolites AFM(1) and AFP(1) in urine. The dynamic range of the method is nearly three orders of magnitude with limits of detection in the low femtogram on column range. The method was validated over a 12-day period by eight analysts. This method is suitable for agricultural, forensic, and public health laboratories during an accidental outbreak or a chemical terrorism event where a rapid and accurate diagnosis of aflatoxicosis is needed.  (+info)

Aflatoxin M1 contamination in raw bulk milk and the presence of aflatoxin B1 in corn supplied to dairy cattle in Japan. (4/28)

Aflatoxin M1 (AFM1) is a hydroxylated metabolite of aflatoxin B1 (AFB1), which has been found in the milk of dairy cattle fed AFB1-contaminated feeds. Since AFM1 has been evaluated as a possible human carcinogen, the cancer risk arising from AFM1 contamination in milk is a serious problem in food safety. To evaluate the risk of AFM1 contamination in milk, it is necessary to analyze the risk factors of AFB1 contamination in corn provided for concentrated feed in Japan. The AFM1 level in domestic raw bulk milk was measured at three sampling times, January, February and June in 2004. The AFB1 contamination in corn supplied to cows was determined at the same time as the sampling of raw milk. The AFM1 contamination levels in milk in January, February and June 2004 were 0.011, 0.007 and 0.005 ng/g, respectively. The AFB1 contamination level in the corn of the concentrated feed was higher from October of 2003 to February of 2004 than from April to June in 2004. This study provides evidence that AFM1 contamination level in milk is parallel to that of AFB1 in corn of concentrated feed, so monitoring of the AFB1 level in corn is important to prevent the risk of AFM1 contamination in milk in Japan.  (+info)

Effects of mycotoxins on chemiluminescent response and cytokine mRNA expression of bovine neutrophils. (6/28)

The effects of aflatoxin B(1) (AFB(1)), aflatoxin M(1) (AFM(1)), deoxynivalenol (DON) and zearalenone (ZEA) on the viability, chemiluminescent (CL) response and expression of cytokine mRNA of bovine neutrophils (PMNs) were evaluated. The opsonized zymosan (OPZ)-stimulated CL response of PMNs was significantly (P < 0.05) decreased by AFB(1) ( > 50 pg/ml), AFM(1) ( > 50 pg/ml) and ZEA (>50 pg/ml). The phorbol myristate acetate (PMA)-stimulated CL response PMNs was significantly (P < 0.05) decreased by AFB(1) (> 0.5 pg/ml), AFM(1) (> 50 pg/ml), ZEA (> 500 pg/ml) and DON ( > 5 pg/ml). Treatment with AFB(1) resulted in reduction in the mRNA expression of interleukin-1beta and tumor necrosis factor-alpha of PMNs stimulated with OPZ and PMA. These results suggest that these four mycotoxins have inhibitory effects on the function of bovine PMNs.  (+info)

Biological reactive intermediates of bisfuranoid mycotoxins. (7/28)

Based on the mode of action of AFB1 and the activities of its biologically active intermediates, one may conclude that: 1. The mode of toxic action of the bisfuranoid mycotoxin is through epoxidation of the vinyl ether double bond of their dihydrobisfuran functionality. 2. The DNA and plasma albumin adducts formed in vivo may be useful in the molecular dosimetry of these environmental carcinogens. 3. Monitoring of these adducts of AFB1 in biological samples so far indicates that aflatoxin is likely involved in the etiology of human liver cancer.  (+info)

Aflatoxin B1 and M1 contamination of animal feeds and milk from urban centers in Kenya. (8/28)

BACKGROUND: Aflatoxin M1 (AFM1) is the principal hydroxylated AFB1 metabolite present in milk of cows fed with a diet contaminated with AFB1and excreted within 12 hours of administration of contaminated feeds. OBJECTIVE: This study was initiated to assess the knowledge and practices of urban dairy farmers and feed millers about aflatoxin in feeds and milk, determine the prevalence and quantify the levels of AFB1 and AFM1 in animal feeds and milk respectively from urban environs in Kenya. METHODS: This work was carried out in the Department of Public Health Pharmacology and Toxicology, University of Nairobi, Kenya, between February 2006 and March 2007. RESULTS: A total of 830 animal feed and 613 milk samples from four urban centers were analyzed for aflatoxin B1 and M1 respectively using competitive enzyme immunoassay. Eighty six percent (353/412) of the feed samples from farmers were positive for aflatoxin B1 and 67% (235/353) of these exceeded the FAO/WHO level of 5micro gKg-1. Eighty one percent (197/243) of the feed samples from feed millers and 87% (153/175) from agrochemical shops were positive, while 58% (115/197) and 66% (92/153) of the positive samples exceeded the FAO/WHO limits respectively. Seventy two percent (315/439) of the milk from dairy farmers, 84% (71/85) from large and medium scale farmers and 99% (88/89) of the pasteurized marketed milk were positive for aflatoxin M1, and 20%, 35% an 31% of positive milk from dairy farmers, medium and large scale farmers and market outlets respectively, exceeded the WHO/FAO levels of 0.05micro g/Kg-1. Sixty seven percent of the urban smallholder dairy farmers had no knowledge that milk could be contaminated with aflatoxin M1 and neither knew how they could mitigate against this exposure. Feed millers knew about aflatoxin B1 in grains and excretion of aflatoxin M1 in milk, but were not alleviating exposure to animals. CONCLUSION: There is need to create awareness and establish routine monitoring of animal feeds and milk to reduce animal and consequently human response.  (+info)

Aflatoxins are mycotoxins produced by two species of Aspergillus, a fungus which is especially found in areas with hot and humid climates.. Aflatoxin M1 and Aflatoxin M2 are major metabolites, being hydroxylated forms, of Aflatoxin B1 and Aflatoxin B2 in humans and animals. M aflatoxins may be present in milk from animals fed on contaminated with Aflatoxin B1 and Aflatoxin B2 feed, leading to the presence of Alfatoxin M1 in the milk.. The Randox Food Diagnostics Aflatoxin M1 FAST ELISA aims to give a fast, reliable, analytical method to detect the presence of Aflatoxin M1. This kit can be used as a screening method for the presence of Aflatoxin M1. ...

Introduction Aflatoxins are generally produced in animal feeds by toxigenic fungi such as Aspergillus flavus, Aspergillus parasiticus and the rare Aspergillus nomius (Kamkar, et al 2011). They are both acutely and chronically toxic, mutagenic, teratogenic and carcinogenic compounds for animal and human (Deshpande, 2002; Ghazani, 2009; Maktabi et al., 2011 and Mohamadi Sani et al., 2012). Aflatoxin M1 (AFM1) is the principle hydroxylated metabolite of aflatoxin B1 which is transformed at the hepatic level by means of cytochrome p450 enzymes and excreted into the milk in the mammary glands of both human and lactating animal after ingestion by the animal of pellets and forage contaminated with aflatoxin B1 (Oveisi et al., 2007; Prandini et al., 2009; Hampikyan et al., 2010; Ayoub et al., 2011). It has been reported that there is a linear relationship between AFM1 in milk and AFB1 in the feed consumed by the animals with approximately 1% to 6% of the ingested AFB1 appearing as AFM1 in milk (Dragacci ...
Strains of Aspergillus species may produce the mycotoxin called aflatoxin in hot humid weather. Aflatoxin is a carcinogen and its metabolite, aflatoxin M1, passes into the milk of cattle ingesting aflatoxin containing feed. Consequently the US Federal Food and Drug Administration has regulations for the amount of aflatoxin allowed in feed for food animals. Specifically, grain may not contain more than 20 ppb (ppb- not ppm) aflatoxin if intended for use in dairy cattle. Milk is checked for aflatoxin at a sensitivity of 0.5 ppb and cattle ingesting as little as 20 to 50 ppb in the total ration may have more than 0.5 ppb aflatoxin M1 in the milk they produce. Aflatoxin in milk is an adulterant so milk containing greater than 0.5 ppb aflatoxin M1 is likely to be dumped with the costs associated with dumping that milk ...
Aflatoxins are produced by the fungi Aspergillus flavus and Aspergillus parasiticus and are common food contaminants in tropical developing countries. Extensive aflatoxin consumption has been shown to be highly associated with liver disease. A case-control study was conducted to determine the association between aflatoxin and liver disease in Kumasi, Ghana. A questionnaire was administered to examine socio-demographic characteristics and food storage and consumption practices, and urine samples were collected to measure levels of the aflatoxin metabolite (AFM1). Two hundred and seventy-six people participated in the study; 38 had liver disease (cases), 136 had neither hepatitis B/C nor liver disease (negative controls), and 102 were hepatitis B/C positive without liver cancer (positive controls). A much higher percent of participants in each group was male (76% of cases, 88% of negative controls and 65% of positive controls). Multivariate analysis showed that age was a significant predictor for being a

Different classes of mycotoxins are distinguished on the basis of the structural similarity and originating mold species. For example, more than a dozen different aflatoxin compounds exist but only five of them are routinely tested (aflatoxins B1, B2, G1, G2, and M1). Aflatoxin B1 is of particular interest because it is listed as a Group 1 Carcinogen by the International Agency for Research on Cancer (IARC). Aflatoxin M1 is a metabolic product that can be present in milk upon ingestion of aflatoxin B1 by an animal. Aflatoxins are ubiquitous in important agricultural commodities including maize and peanuts, and are among the most studied mycotoxins.. Deoxynivalenol (DON) is produced by a different fungi species. It is prevalent in cereal crops grown under wet conditions and temperatures above 15o C (60o F). Chronic exposure of livestock to DON may result in slowed growth, impaired immune function and reduced rates of reproduction, particularly in non-ruminants.. Mycotoxins were discovered as the ...
Mycotoxins are chemical compounds that have different structures and different biological effects. They are having high acute toxicity, which is often associated with malignant diseases. Aflatoxins are a group of mycotoxins which synthesize a limited number of strains molds of the genera Aspergillus, Penicillium and Fusarium. The most important aflatoxins, related to milk and milk products, are: B1 and B2 (present in the feed of animals) and M1 and M2 (hydroderivates aflatoxin B1 and B2). They are excreted in milk, urine and stool. Fortunately, there is a large gap between the concentration of toxins in feed and the amount of residues in animal products. Ratio of aflatoxin B1 and aflatoxin M1 in milk is about 300:1. For the determination of aflatoxin, today are commonly used imunoassays (ELISA - Enzyme-linked immunosorbent assay) during routine analysis because they are very simple and quick. If the positive result of ELISA, confirmatory methods are conducted which are far more sensitive and ...

ITRAQ/TMT reporter intensity boxplots of all PSMs for each channel and Raw file. The opacity (alpha value) of the bar correlates to the number of PSMs with non-zero abundance (1.0 = full labeling; 0.0 = no reporter ions; see heatmap scoring below).. There is a similar Experimental Group based metric/plot based on proteins.txt.. PTXQC uses isotope-corrected intensities (eliminating channel carry-over) to allow for detection of empty channels, e.g. due to mis-labeling. If MaxQuant did no isotope correction (i.e. corrected and uncorrected channels are equal), the plot title will show a warning. The scores are too optimistic in this case (since carry-over will be mistaken for actual signal).. Note: global labelling efficiency can only be judged indirectly with this metric, since isobaric reporters where set as fixed modification. Thus, MaxQuant. will only identify labeled peptides in the first place. Observing only very few peptides (see peptide count metric), is a good indicator. However, if only ...

Ulexite, like other borates, is a structurally complex mineral. The basic structure of ulexite contains chains of sodium, water and hydroxide octahedrons linked in endless chains. The chains are linked together by calcium, water, hydroxide and oxygen polyhedra and massive boron units. The basic boron unit has a formula of B5O6(OH)6 and a charge of negative three (-3). It is composed of three borate tetrahedrons and two borate triangular groups. Ulexite is found with the mineral borax and is directly deposited in arid regions from the evaporation of water in intermittent lakes called playas. The playas form only during rainy seasons due to runoff from nearby mountains. The runoff is rich in the element boron and is highly concentrated by evaporation in the arid climate. Eventually the concentration is so great that crystals of ulexite, borax and other boron minerals form and accumulate to great thickness. Specimens of ulexite may form a cotton ball tuft of acicular crystals. These can be ...

Loss of platelet quality during ex vivo storage is a major concern in the transfusion medicine field and it has been known that platelet mitochondrial dysfunction is associated with storage time. In the last decade, small noncoding RNAs also known as microRNAs (miRNAs) have been reported to regulate key cellular processes through their target sequence interactions with selected mRNAs. In this study, we focused on understanding the mechanisms of platelet mitochondrial dysfunction during storage through miRNA regulation of mRNAs. RNA was isolated from day 0, day 5, and day 9 of stored human leukocyte-depleted platelets and subjected to differential miRNA and mRNA profiling. The miRNA profiling identified several miRNAs at low levels including a set of 12 different miR-548 family members (miR-548a-3p, miR-548aa, miR-548x, miR-548ac, miR-548c-3p, miR-603, miR-548aj, miR-548ae, miR-548z, miR-548u, miR-548al, and miR-570-3p).

Acute aflatoxin exposure can cause death and disease (aflatoxicosis) in humans. Aflatoxicosis fatality rates have been documented to be as high as 40% in Kenya. The inclusion in the diet of calcium silicate 100 (ACCS100), a calcium montmorillonite clay, may reduce aflatoxin bioavailability, thus potentially decreasing the risk of aflatoxicosis. We investigated the efficacy, acceptability and palatability of ACCS100 in a population in Kenya with recurring aflatoxicosis outbreaks. Healthy adult participants were enrolled in this double-blinded, crossover clinical trial in 2014. Following informed consent, participants (n = 50) were randomised to receive either ACCS100 (3 g day-1) or placebo (3 g day-1) for 7 days. Treatments were switched following a 5-day washout period. Urine samples were collected daily and assessed for urinary aflatoxin M1 (AFM1). Blood samples were collected at the beginning and end of the trial and assessed for aflatoxin B1-lysine adducts from serum albumin (AFB1-lys). AFM1 ...
Molecular dynamics and reverse Monte Carlo simulations are used to investigate the structure of calcium aluminosilicate glasses with low silica content. The polymerized network is close to that expected from a random distribution for all compositions with important amount of Al-O-Al linkages. Minor species such as triclusters and free oxygen atoms are present. The main structural variations are the changes in the ring size distribution or the Qn distribution. The ring statistics indicate the presence of 4-membered rings, with larger rings at high silica content. We observe that Al enters preferentially the tetrahedral polymerized units with increasing SiO2. A noteworthy structural property of the structure of these glasses is the presence of a significant amount of non-bridging oxygens, even in the fully charge-compensated glasses. The Ca environment correspond to a distorted polyhedra with seven oxygen neighbors. The variation of the glass transition temperature of these glasses are explained based on

N2 - Objective: Evidence from the 1944-1995 Dutch Hunger Winter and the 1959-1961 Chinese famines suggests that those conceived or in early gestation during famines, have a 2-fold increased risk of developing schizophrenia in adult life. We tested the hypothesis in a second Chinese population and also determined whether risk differed between urban and rural areas. Method: The risk of schizophrenia was examined in Liuzhou prefecture of Guangxi autonomous region. Rates were compared among those conceived before, during, and after the famine years. Based on the decline in birth rates, we predicted that those born in 1960 and 1961 would have been exposed to ...

Aflatoxin-producing fungi contaminate food and feed during pre-harvest, storage and processing periods. Once consumed, aflatoxins (AFs) accumulate in tissues, causing illnesses in animals and humans. Most human exposure to AF seems to be a result of consumption of contaminated plant and animal products. The policy of blending and dilution of grain containing higher levels of aflatoxins with uncontaminated grains for use in animal feed implicitly assumes that the deleterious effects of low levels of the toxins are linearly correlated to concentration. This assumption may not be justified, since it involves extrapolation of these nontoxic levels in feed, which are not of further concern. To develop a better understanding of the significance of low dose effects, in the present study, we developed quantitative methods for the detection of biologically active aflatoxin B1 (AFB1) in Vero cells by two independent assays: the green fluorescent protein (GFP) assay, as a measure of protein synthesis by the cells,

AU - Groopman, John D.. AU - Kamataki, Tetsuya. PY - 1997. Y1 - 1997. N2 - The in vivo activation of aflatoxin B1 (AFB1) was assessed by using two transgenic mouse lines, M2 and M10, in which the human fetus-specific CYP3A7 was expressed in the kidney (M2) and the liver (M10), respectively. Male mice of 8 weeks old from these two lines were treated with a single i.p. injection of AFB1 (4 mg/kg body weight). AFB1-N7-guanine adduct was quantified by high-performance liquid chromatography. DNA damage was measured using the alkaline elution technique 2 and 6 h after AFB1 treatment. Administration of AFB1 resulted in a significantly higher level of AFB1- N7-guanine in the livers of M10 transgenic mice compared with their nontransgenic littermates (16.5 ± 4.2 versus 10.4 ± 1.2 ng/mg DNA, P , 0.01). The level ...

Design a symmetric protein tetramer, with 4 identical chains that assemble together! This puzzle includes a Secondary Structure Objective, so no more than 50% of your design can form helices. The H-bond Network Objective encourages players to build buried, satisfied H-bond networks at the interface between symmetric chains. H-bond networks are a great way to introduce polar residues at the interface, but its important that all of the bondable atoms make hydrogen bonds! Weve also adjusted the H-bond Network Objective so that poor-scoring H-bonds may not contribute to networks; poor-scoring H-bonds will be displayed in red. This puzzle uses the Buried Unsats Objective, with a large penalty for buried polar atoms that cant make H-bonds. In this puzzle, there are no limits on the Complex Core, but weve included the Complex Core objective so players can see the core residues that can be incorporated into H-bond Networks ...
