The aim of this experiment was to evaluate the direct effect of genistein, daidzein and zearalenone on basal and hormone-induced lipogenesis and lipolysis in isolated rat adipocytes. In lipogenesis, daidzein and zearalenone were used at concentrations of 0.01, 0.1 and 1 mmol x L(-1) and genistein at concentrations of 0.01, 0.3, 0.6 and 1 mmol x L(-1). In lipolysis, concentrations of tested comp...

Zearalenone contamination of 175 wheat samples produced in 2004 in Golestan province, northern Iran was determined. The 10-20 kg samples collected at different stages, including pre-harvest, before and after storage for 2 months in local silos. Samples were ground and sub-sampled with an analytical Romer mill. Each sample extract was cleaned-up using an immunoaffinity column. Zearalenone levels...

Glutathione S-transferase (GST) activity pattern was determined in tolerant (cv. Sumai#3) and susceptible (cv. Falat) wheat heads inoculated with Fusarium graminearum, the causal agent of head scab disease (FHB), during various developmental stages. GST specific activity exhibited a transient pattern in Sumai#3 reaching a maximum level at the milk stage and declining thereafter. GST level in Su...

fusarium is a fungus that is commonly found as saprophytes with parasitic life on some living organisms. mycoprotein or fungus proteins with physical and chemical features are known as food in recent years. when they are involved in temperature and wet stress, release materials such as mycotoxins or fungus toxins remained in food. zearalenone and dependent compounds have distinct role in many f...

mycotoxins are small, toxic chemical products produced as secondary metabolites by a few fungal spices that readily colonise crops and contaminate them with toxins in the field or after harvest. in this study a liquid chromatographic method was developed for the simultaneous determination of aflatoxins (afs) (b 1 , b 2 , g 1 , and g2), ochratoxin a (ota) and zearalenone(zea) toxins in wheat. fo...

The mycoflora, levels of afllatoxins and the presence of ochratoxin A and zearalenone in nuts of Cola acuminata and C. nitida were determined immediately after curing and after 3, 6 and 9 months of storage in leaf-lined baskets. Five field fungi and 11 storage fungi were isolated. Aspergillus, Penicillium and Fusarium were the predominant genera. None of the target toxins was detected immediate...

Abstract Fusarium spp. are phytopathogens causing fusarium head blight in wheat. They produce mycotoxins, mainly fumonisins, deoxynivalenol, and zearalenone. The study was conducted during two growing seasons (2020 2021) at the experimental field laboratories of Hungarian University Agriculture Life Sciences (MATE). aim to determine influence season, nitrogen fertilisation, wheat variety on inf...

Zearalenone [6-(10-hydroxy-6-oxo-trans-1-undecenyl)-ß-resorcyclic acid lactone] is a mycotoxin produced as a secondary metabolite of various Fusarium fungi (see Figure 1). ZON is also known as RAL, F-2 toxin or ZAR. Zearalenone (ZON) has been detected in a variety of cereal products such as wheat, maize, barley, oats, rice and sorghum as well as beer that has been produced with contaminated gra...
