Coreplication experiments have revealed that replication of
turnip yellow mosaic virus (TYMV) RNA in turnip protoplasts is cis-preferential.
Genomes encoding mutant p141 or p66, proteins
essential for virus replication, were inefficiently rescued by a
helper genome. One model for the cis-preferential replication of
TYMV is that p66 and p141 form...
Although the occurrence of ketosis is a postpartum phenomenon, recent studies have
focused on the prepartum period as key in the development of the disorder. Indicators of
prepartum energy status, such as depressed dry matter intake (DMI) and elevated plasma
non-esterified fatty acid (NEFA) concentrations have been associated with the...
Red wine texture is a particularly important property of overall red wine quality
whose origin is not well understood. The overall goal of this study was to improve our
understanding of how chemical composition influences red wine texture. Unlike
previous studies that have used model systems to investigate how chemical...
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...
5'-Deoxy-5'-methylthioadenosine phosphorylase catalyzes
the phosphorolytic cleavage of 5'-deoxy-5'-methylthioadenosine
to form 5'-deoxy-5'-methylthioribose-1-phosphate and
adenine in mammalian cells and plays an important role in
methionine and purine salvage. The enzyme is abundant in
normal tissues and in cell lines derived from normal cells.
However, several malignant tissues and cell lines have been...
Shrimp waste samples were extracted with a variety of organic solvents. Each fraction was measured for antioxidant activity by determining the rate of oxidation of β-carotene-linoleic acid in an emulsion system. An ethanol extract exhibited the highest antioxidant activity. Purification of the most active fraction was accomplished by thin layer...
Microgard, a commercially-available pasteurized
fermented milk, was found inhibitory to gram negative
bacteria such as Pseudomonas putida, some well-known foodborne
pathogens (e.g. Salmonella, Yersinia and Aeromonas)
and some fungi as revealed by an agar incorporation assay
method. Gram positive bacteria, however, were not
inhibited. Rather, some bacteria in this group...
An F₁ population resulting from mating pygmy and normal goats (local commercial breeds) was crossed to give an F₂ population. Analysis of wither height and body weight indicated that the F₂ population was intermediate between the parental types (pygmy and normal) with little overlap of phenotypic values for body size...
