For ras gene mutation analysis in the rainbow trout (Oncorhynchus
mykiss) model system, a partial trout ras sequence was identified
using the polymerase chain reaction (PCR). Two synthetic
oligonucleotides based on rat K-ras gene sequence were used as
primers for the PCR procedure. A 90 base pair (bp) sequence,
referred...
Ammonia (NH₃) volatilization can result in a substantial amount of surface applied nitrogen (N) being lost into the atmosphere, making it an environmental pollutant as well as reducing plant-available N. However, N can also be easily lost from the soil through leaching,
and nitrous oxide (NO₂). Enhanced efficiency N fertilizers...
Marine algae have been recognized as a rich resource of new
and unusual organic molecules with diverse biological properties.
The current need to develop new antifungal, anticancer, antibiotic
and antiviral drugs has led to an intense research effort into the
discovery, isolation and structure determination of potential
medicinal agents from...
The purpose of this study was to understand the vulnerability and adaptive capacity of shellfish stakeholders in the Pacific Northwest who are adapting to ocean acidification (OA). This study developed a geovisualization tool of existing environmental data for assessing species-specific risk profiles to OA (based on their exposure and sensitivity),...
I. THE EFFECT OF FEEDING PROGRAMS ON REPRODUCTIVE TRAITS AND
SELECTED BLOOD CHEMISTRIES OF CAGED BROILER BREEDER MALES:
1. FEED RESTRICTION LEVELS:
The effects of five different feeding levels (136, 125, 113,
102, and 91 g/male/day of a 13.1% crude protein (CP), 3167 kcal ME/kg
feed) on the reproductive traits...
Marine organisms produce a variety of secondary metabolites for defense, communication, and reproduction. While these uses are essential for the organisms' survival, marine natural products have demonstrated their value to human society as well. Asian countries used algae for centuries to treat or prevent illnesses as wide-ranging as cough, gout,...
The Western Lake Survey (WLS) of 1985 documented the status of lake water chemistry across the western US and inferred population representations of various subregions and geomorphic units via statistically analyses. Results from this 1985 study indicated that lakes of the Oregon Cascades had the second most pristine and dilute...
