Dietary cyclopropenoid fatty acids (CPFA) have long
been known to cause pronounced physiological disorders in
both farm and laboratory animals. Past work has shown
CPFA to be a powerful promoter of carcinogenesis in trout,
rats and mice. Sterculic and malvalic acids (CPFA's) are
found in seed lipids of plants from...
The bioavailability of vitamin B-6 from four selected
foods was investigated in five men, aged 22 to 25 years,
who were receiving a pyridoxine supplement. The subjects
received a constant diet containing 1.34 mg of vitamin B-6
throughout this five-week study, except on Saturdays and
Sundays when they ate their...
Western Oregon receives a surplus of rainfall during fall, winter, and early spring months. Temperature and soil fertility are the principal factors limiting growth during this period. If livestock producers are to take full advantage of the forage potential of this area, it is necessary for them to supply plant...
Maternally-derived transcripts and proteins support early bovine and ovine embryo development until the 8- to 16-cell stage, at which time embryonic transcripts become essential for continued development. One purported mechanism for the switch from maternal to zygotic control of development (maternal to zygotic genome activation; MZGA) is the appearance of...
The reaction of several primary amines with nitrite was investigated
with regard to the formation of N-nitrosamines. When reacted
in a low moisture system at 160°C with a 1:2 molar ratio of amine to
sodium nitrite, various primary amine hydrochloride salts were found
to give rise to heterocyclic nitrosamines. The...
Corn oil (CO) and Sterculic foetida oil (SFO) fed rats were
injected with [9, 10-methylene-¹⁴C]sterculic acid. Less than 1%
of the label was expired as carbon dioxide. The majority of the
label was excreted in the urine as short-chain dicarboxylic acids with
an intact cyclopropane ring. The major metabolites for...
Early embryo development is dependent on maternally derived RNA and protein synthesized during oogenesis. In the bovine embryo this dependence lasts until the 8-16 cell stage, at which time embryonic transcripts become essential for continued development. One proposed mechanism for this transition from maternal to zygotic control of development (maternal...

Many parts of the West are experiencing substantial growth pressures that have increased the demand for water. These new demands come at a time when most of the water in the West has been fully appropriated by traditional uses such as agriculture, mining, and industry. Some attempts are being made...
Three studies were designed to evaluate the promoting
effect of cyclopropenoid fatty acids (CPFA) on avian myeloblastosis
virus (AMV) infection in White Leghorn chickens.
In the first study effects on growth parameters, blood serum
and erythrocyte lipid composition of White Leghorn chickens
were investigated at 100 ppm and 300 ppm...
