In this research, a model system for studying the effects of the toxic metabolite, methylglyoxal, was created using Chinese Hamster Ovary (CHO) cells which produce tissue plasminogen activator (t-PA). The human gene for glyoxalase I was subcloned into an inducible mammalian expression vector. This vector was then used to create...
The purpose of the work is to enable students of botany to identify
accurately Oregon ferns, both as living plants and as dried specimens.
Therefore, it provides vegetative keys to the families, genera
and species of the ferns (Class FILICINAE) found in Oregon. Correct
names have been determined using the...
The gonadal steroids, testosterone and estradiol, are known to be important
modulators of neuronal functions and behaviors in most vertebrate species. These
steroid hormones also elicit changes in neuropeptide synthesis and secretion, alter
specific neurohormone receptor levels, and alter neuronal morphology and
electrophysiology. Many of the actions of androgens and...
An investigation of the correlation between a number of behavioral,
morphological and physiological parameters and dominance status of male
Ring-necked Pheasants (Phasianus colchicus) was undertaken. Dominant
males performed significantly more aggressive behaviors than
subordinates and a higher proportion of these behaviors was directed
toward distantly ranked subordinates. Animals could also...
Tissue differentiation of the primary root and its associated
laterals is reported. Secretory elements are the first of the primary
tissues to mature. They appear to be located between the precursory
phloem and pericycle in the primary root, but are more closely
associated with the pericycle in long lateral roots....
