The rainbow trout (Oncorhynchus mykiss) model
of chemical carcinogenesis is becoming increasingly
important as a supplement to rodent studies. However,
much of the molecular biology of the carcinogenic
response is still unknown in the trout model. The ras
gene family has been implicated in the tumorigenesis of
both spontaneous and...
The goal of this study was to gather information on the autecology,
reproductive ecology, and population dynamics of Astragalus australis
var. olympicus as a baseline for conservation strategies and to help
explain its restricted range. Approximately four thousand
individuals occurred in four known population centers in the Olympic
Mountains, Olympic...
Two experiments involving interactions between wheat
(Triticum aesitivium L.) cultivars and rust pathogens were
investigated. One experiment evaluated the aggressiveness
(measured by infection efficiency and latent period) of
populations of Puccinia recondita Rob. when inoculated on
the cultivar they were isolated from, their "own" cultivar,
and when inoculated onto other...
We investigated the effect of pyridoxine
supplementation on the utilization of protein in a low-protein,
plant-based diet in four subjects (2 men and
2 women), aged 21 to 38 years. Following two days of a
negligible protein diet, this 34 day study was divided into
three dietary periods: the subjects...
An experiment was conducted to determine the
suitability of a new variety of yellow pea (Pisum sativum
L., var. Miranda) as a feed ingredient in broiler breeder
diets. Two-hundred twenty-five I S A Vedette dwarf broiler
breeder pullets were fed either a corn-soy (CS) or corn-pea
(CP) diet from day...
Deposition of the Middle Devonian part of the Denay Limestone
and Bay State Dolomite in the northern Antelope Range and Fish
Creek Range, respectively, took place on and in front of a carbonate
platform with a lime sand shoal at the shelf edge. In the Givetian part
of the Denay...
A 2-year field study was conducted on the effects of two sulfur
fertilizers (calcium sulfate or elemental S, 0 or 50 kg S ha⁻¹ yr⁻¹)
on the distribution of sulfur fractions (inorganic sulfate, C-bonded,
ester sulfate, and residual S), arylsulfatase enzyme activity, and
microbial biomass carbon (C) and sulfur (S)...
Conditions were established for inducing pear blossom blast
caused by Pseudomonas syringae (Ps) on both attached and detached
shoots. The incidence of disease was proportional to the log of Ps
population under optimal temperature, moisture and bloom developmental
stage. Highest incidence of infection followed occurrence of a major
exotherm in...
