Three commercial sausage starter cultures were grown in
an internal-pH-controlled medium (PHASE 4) and in a soluble
phosphate-buffered medium. The cultures were tested by
comparing viable counts before and after freezing at -40 C
or freeze-drying and subsequent storage for 3 months in the
frozen or dried state. Strains varied...
It was hypothesized that alterations in plasma concentrations of
corticosterone (CS) and prolactin (PRL) may be at least partially responsible
for polychlorinated biphenyl (PCB)-induced immunosuppression.
A 2 by 2 factorial experiment examined the interactions of PCB and P815,
an allogeneic tumor, on plasma concentrations of CS and PRL, and on...
Two studies were conducted to determine the effects of zinc (Zn), copper (Cu) and/or selenium (Se) on the humoral immune response of weaned steers fed diets deficient in these minerals. Steers were bled weekly for eight weeks to measure plasma mineral levels. Humoral immune response was measured as antibody response...
Declines in wild salmonid (Oncorhynchus spp.) populations in the Columbia River basin have resulted in managers identifying that avian predation on juvenile salmonids is an important limiting factor for salmonid recovery. Caspian Terns (Hydroprogne caspia), particularly those nesting in the Columbia River estuary, were identified as key avian predators that...
Spatial, diel and seasonal variations in dissolved oxygen and
temperature were measured in Triangle Lake, Oregon. Spatial dissolved
oxygen and temperature variations measured in the stratified
lake are presented to illustrate the horizontal uniformity of the lake
and to demonstrate the applicability of the one dimensional assumption
for sampling and...
