Determination of aflatoxins in individual peanuts and peanut sections

Subsamples of a given lot of peanuts may vary greatly in aflatoxin content due to extreme variability in the degree of contamination of individual kernels. A micro method, adapted from the aqueous acetone procedure recently proposed by Pons and Goldblatt for the determination of aflatoxins in cottonseed products, was developed to permit accurate determination of aflatoxins in individual kernels and kernel sections. Use of this procedure permitted the topographic distribution of aflatoxins within single kernels to be mapped and indicated that the toxins are not uniformly distributed within contaminated kernels, even when the kernel contains a high level of aflatoxins. Although wrinkling or discoloration sometimes indicated that a kernel was contaminated, this type of physical damage was not found to be a reliable indication of aflatoxin content. Also it was noted that a few apparently sound and mature kernels contained high levels of aflatoxins. Presented at the AOCS Meeting, Houston, April 1965. Honorable Mention Bond Award Competition. So.

Religious affiliation and psychopathology in a Mexican-American population.

Studied 54 Protestant and 54 Catholic Mexican-American Ss of similar levels of acculturation, education, and socioeconomic background. Evaluations of psychopathology were derived from the L-R sections of the Cornell Medical Index and behavioral observations. The lower rate of pathological responses by Protestant Ss was attributed to the social support offered by the small, intimate congregations with their strong, paternal leadership and the Protestant doctrines of asceticism and individual responsibility which contribute to impulse control.
