Molecularly imprinted photoelectrochemical sensor for fumonisin B1 based on GO-CdS heterojunction.

Biosensors & bioelectronics, 2019
A rapid and ultrasensitive molecularly imprinted photoelectrochemical (MIP-PEC) sensing platform based on ITO electrode modified with GO-CdS heterojunction was prepared for ultrasensitive measure of fumonisin B1 (FB1).

Effects of Fumonisin B1 in Pregnant Rats

Food and Chemical Toxicology, 1998
Fumonisin B1 (FB1), the major mycotoxin from Fusarium moniliforme, has been implicated as a causative agent in several animal and human diseases. Despite animal toxicity studies and human epidemiological studies of FB1, knowledge of its reproductive effects is scarce.

Molecular mechanisms of fumonisin B1-induced toxicities and its applications in the mechanism-based interventions.

Toxicon, 2019
Fumonisin B1 (FB1), the most toxic member of fumonisins, is one of the most common mycotoxins contaminating feed and food. It has been shown to produce pleiotropic toxicities in animals including neurotoxicity, hepatotoxicity and nephrotoxicity, and with

Developmental effects of fumonisin B1 in mice

Mycopathologia, 1996
Developmental and toxic effects of aqueous extracts of F. moniliforme culture material containing known levels of fumonisin B1 were recently reported in mice and included maternal hepatotoxicity and lethality, maternal body weight gain reduction, increased embryonic resorptions, reduced offspring body weights, and fetal malformations including cleft ...

DNA Damage in Astrocytes Exposed to Fumonisin B1

Neurochemical Research, 2002
Fumonisins are a group of toxic metabolites mainly produced by Fusarium moniliforme and Fusarium proliferatum, fungi that commonly occur on corn throughout the world. Fumonisin B1 (FB1), structurally resembling sphingoid bases, is an inhibitor of ceramide synthase, a key enzyme involved in de novo sphingolipid biosynthesis and in the reacylation of ...

Detection of fumonisins B1, B2, and B3 and hydrolyzed fumonisin B1 in corn-containing foods

Journal of Agricultural and Food Chemistry, 1993
Selected corn-containing foods were analyzed for the presence of fumonisins B 1 , B 2 and B 3 (FB 1 , FB 2 , and FB 3 ) and hydrolyzed fumonisin B 1 (HFB 1 ). Samples were extracted with H 2 O/CH 3 CN (1:1). Following a cleanup procedure using a C 18 SPE cartridge, analytical reversed-phase HPLC and fluorometric detection of the o-phthaldialdehyde ...

Fumonisin B1 alters sphingolipid metabolism and immune function in BALB/c mice: Immunological responses to fumonisin B1

Mycopathologia, 1995
Fumonisins have been reported to have diverse effects on animals, including immunosuppression in chickens and feeder calves; therefore, the effects of fumonisin B1 (FB1) on immune function in BALB/c mice was investigated. When administered i.p. with sheep red blood cells (SRBC), 5 to 100 micrograms of FB1 reduced the number of plaque-forming cells (PFC)

Hydrolyzed fumonisin B1 induces less inflammatory responses than fumonisin B1 in the co-culture model of porcine intestinal epithelial and immune cells.

Toxicology Letters, 2019
Fumonisin B1 (FB1), mainly produced by Fusarium verticillioides and Fusarium proliferatum, can be converted to the less toxic metabolite hydrolyzed FB1 (HFB1) by enzymatic degradation.

Chemical Transformation of Hydrolyzed Fumonisin B1 to Hydrolyzed Fumonisin B2

Journal of Agricultural and Food Chemistry, 1995
The fumonisins, a series of sphingosine-analog mycotoxins produced by the ubiquitous corn contaminant Fusarium moniliforme, are an important food safety concern because they are tumor promoters with sufficient chemical stability to persist through normal food processing.

Fumonisin B1 and the kidney: Modes of action for renal tumor formation by fumonisin B1 in rodents

Food and Chemical Toxicology, 2012
The mycotoxin fumonisin B1 (FB1) is an important contaminant of maize and maize-based products. In rodent toxicity studies, FB1 was shown to be hepato- and nephrotoxic, and to induce renal tumors in rats when administered via the diet. Of particular note are the aggressive growth characteristics of FB1-induced tumors with a high potential to ...
