Pineal acetylserotonin methyltransferase (ASMT) activities
in rainbow trout were reported on by Hafeez and Quay (1971). The validity of certain
assay parameters used by these researchers
were investigated. With the exception of incubation temperature,
all parameters studied proved to be quite valid. Temperature
studies indicated a low stability for trout...
Dietary protein intake has been observed to influence the induction
of cancer in animals exposed to carcinogens, presumably by affecting the
activities of enzyme systems which metabolize them. One such carcinogen
is aflatoxin B₁ (AFB₁) a mold metabolite and frequent contaminant of
foodstuffs. Variations in the levels of dietary proteins...
