Mycotoxins are compounds produced by fungi which grow on various groups ranging from grains to fruits, vegetables, nuts and spices. Mycotoxins can be harmful to humans and livestock through consumption of contaminated crops; therefore, mycotoxin levels are monitored in foods to minimize the risk of ingestion. Regulatory agencies around the globe set Maximum Residue Limits (MRLs), which range from <10 to >500ppb to ensure harmful levels of mycotoxins do not enter the food supply. It is important to have the ability to detect and accurately quantify mycotoxin contents at low levels across various food matrices, as each matrix composition poses different challenges in detection.
In this study, we demonstrate the accurate and sensitive quantification of up to 12 regulated mycotoxin compounds in three commonly regulated foods using the novel Ultivo triple quad LC/MS.
From Farm to Landfill: Results of a Campus-Community Awareness Event to Promote Sustainable Food SystemsPoster
In April 2017, a campus-community event (N=42 participants) was held to promote sustainable food systems by educating participants about concepts ranging from food production to nutrition and food waste management. This poster discusses the resulting increased awareness and knowledge of a our local food system among participants, which can be fostered through educational events that combine opportunities for research, teaching, and practice.READ MORE
Comparing The Anti-Alzheimer's Activity of Different Types of CoffeePoster
This study found that coffee solutions treated at 5% are toxic to neurons. However, the toxicity reduced significantly at 2.5%. While the toxicity was significantly less allowing for more cells to survive at 2.5%, the levels of toxic amyloid beta 1-42 significantly reduced. This reduction in amyloid beta is associated with improvement in cognitive performance, as the presence of these toxic peptides is one of the characteristics of AD pathophysiology.READ MORE
C1 Complement mediates human cord blood serum derived APP α-secretase cleavage activity in vitroPoster
Our results indicate that CBS contains proteins that promote α-secretase like enzymatic activity. LC-MS/MS analysis in CBSF and AgBSF revealed the presence of 142 proteins of which C1 subunits and alpha-2-macroglobulin showed significantly greater levels in αCBSF compared with αAgBSF. further study showed,C1 subunits can enhance sAPPα production and Aβ reduction in cell culture conditionREAD MORE
