A set of genes which show developmental and tissue
specificity are expressed late in embryo maturation during
grain formation in wheat (Triticum aestivum). Two members
of this maturation gene set (MGS) are Em and triticin, a 7S
globulin. Results presented here show that during
embryogenesis, the expression of Em mRNA...
Red fir (Abies magnifica) is a high elevation conifer generally growing between an altitude of 1,400 and 2,700 meters. In California, red fir grows in the Sierra Nevada, the Klamath Mountains, the eastern edges of the northern Californian Coast Ranges, and in the southern Cascades. Red fir commonly grows in...
The quality of macromolecular crystal structures depends, in part, on the quality and quantity of the data used to produce them. Here, we review recent shifts in our understanding of how to use data quality indicators to select a high resolution cutoff that leads to the best model, and of...
A study of malolactic bacteria of the Leuconostoc
genus, especially L. oenos, and their bacteriophages was
conducted. A search for the presence of infectious
bacteriophages in grapes, musts, and juices employed in
malo-lactic fermentation (MLF) was conducted; no
evidence, either physical or biological, was found for
the existence of these...
Genomic instability drives tumorigenesis, but how it is initiated in sporadic neoplasias is unknown. In early preneoplasias, alterations at chromosome fragile sites arise due to DNA replication stress. A frequent, perhaps earliest, genetic alteration in preneoplasias is deletion within the fragile FRA3B/FHIT locus, leading to loss of Fhit protein expression....
These studies were conducted to examine the
influence of several variables on the growth hormone binding
protein (GHBP) in serum of pigs. Continuous long term
porcine somatotropin (pST) injections (daily for 6-7 wk)
increased GHBP activity (p < .05). However, periodic short
term pST injections (daily, every second d or...
Growth hormone binding protein (GHBP) may be an important
factor in the regulation of growth as well as an indirect,
less invasive way of predicting the status of growth hormone
receptors. Several factors (age, nutritional status, sex,
and glucocorticoid administration) have been reported to
influence circulating growth hormone (GH) levels,...
This study was conducted to determine the effects of
shipping stress on the immune system in domestic lambs (Ovis
aries) and to determine the potential of the thymic peptide,
thymulin, to reduce those effects of stress on the immune
system. Treatments consisted of no shipping (as unstressed
controls), shipping (as...
The continuation of geoarchaeological investigations at Tseriadun (35CU7) contributes to the understanding of the site's depositional history and the associated environments, thereby identifying the long term geomorphic change in the area and providing the environmental context for local human activity as it is reflected in the archaeological record. Meeting this...
