Ochratoxin A (OTA) is one of the most abundant food-contaminating mycotoxins. Its occurrence in several agricultural commodities has been considered a worldwide problem. This toxin is mainly produced by Aspergillus species. OTA has nephrotoxic, immunosuppressive, and carcinogenic effects and consequently the contamination with this toxin represents a high risk for human and animal health. In th...

As Mexico is located within Mesoamerica, it is considered the site where the bean plant originated and where it was domesticated. Beans have been an integral part of the Mexican diet for thousands of years. Within the country, there are a number of genotypes possessing highly diverse physical and chemical properties. This review describes the major bioactive compounds contained on the Mexican v...

This work reports on two courses for computer scientists. The first is a graduate course on modeling and simulation and the second is a course on component based software engineering. For both of these courses we principally use the same basis, that is, the Java Beans component technology and the DEVS system theory formalism for discrete event simulation. However, in the two coursed, we pursue ...

Beans require adequate amounts of all essential plant nutrients for optimum growth but only a few nutrients are documented to be needed for southern Idaho soils. These nutrients include phosphorus (P), nitrogen (N), zinc (Zn), potassium (K), sulfur (S), and to a much less extent B, Cu, Mn and Fe. University of Idaho Agricultural Experiment Station research as well as research from throughout th...

The effects of extrusion conditions on cooking degree, flour dispersion viscosity and mineral potential availability of extruded bean flour were studied. Phaseolus vulgaris beans of the agronomic cultivar "Flor de mayo" were ground and dehulled to obtain grits and then extruded at different temperatures (140, 160 and 180 degrees C) and moisture contents (17, 20 and 23%), according to a bifactor...

Purple acid phosphatases are binuclear metalloenzymes, which catalyze the conversion of orthophosphoric monoesters to alcohol and orthophosphate. The enzyme from red kidney beans is characterized with a Fe(III)-Zn(II) active center. So far, the reaction mechanisms postulated for PAPs assume the essentiality of two amino acids, residing near the bimetallic active site. Based on the amino acid se...
