The gut microbiome has been previously implemented in a number of diseases. Of note is its substantial role in metabolic syndrome, which encapsulates a group of conditions that increase the risk of cardiovascular disease, type 2 diabetes, and stroke. Understanding the causal relationships between the gut microbiome and host processes...
This thesis is a collection of four submitted manuscripts that present
methods to assist forest ecosystem service managers wanting to develop
operational sampling, monitoring, and production plans for a set of
specific quantifiable ecosystem services, which are formulated as a
series of general multi-objective optimization problems. The problems
are solved...
Two light sensitive mutants of the green alga Scenedesmus obliquus strain D₃ have been characterized. The photodynamic nature of their sensitivity has been established, the subchloroplast site of photodamage has been investigated, and their noncarotenogenic character has been verified. The two mutants possess several similarities, although mutant L. S. -41...
A new photosystem-II mutant of the green alga Scenedesmus
obliquus D₃, strain PS-28, has been shown to lack a-tocopherol
(vitamin E). The photosynthetic activity of dark grown samples of
PS-28 is about 20% of the wild-type control. Culturing the mutant
at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic
activity...
The effects of ultraviolet (UV) irradiation on photosynthesis and
various partial reactions involving the individual photoreactions of
photosynthesis were examined. These reactions included photo-reduction in adapted green algae, Hill reaction, cyclic photophosphorylation,
the 520 nm absorbance change and variable-yield fluorescence.
The reactions were measured in spinach chloroplasts and
isolated chloroplasts...
Partial reactions of photosynthesis were examined in the wild
type strain and six photosynthetic mutants (8, 11, 26, 40, 50, a') of
Scenedesmus obliquus, strain D₃. A reproducible procedure for the
isolation of active chloroplast fragments from Scenedesmus was
developed. Several chloroplast reactions were examined, as well
as two in...
Life history attributes and apparent distributional
patterns suggest that Plethodon dunni exists as small, semi-isolated
populations throughout its range. Isozyme and morphological
variation in this species was examined to determine
any possible geographic trends.
Starch gel electrophoresis was utilized to examine
genetic variation at 24 isozyme loci in 287 individuals...
Experiments were conducted to characterize the nongenomic effects of
progesterone (P4) on binding of oxytocin (OT) to the ovine oxytocin
receptor (OTR) and signal transduction. The dose-response relationship of
P4 to OT binding to the OTR in endometrium was examined. Progesterone
interfered with the binding of OT to the OTR...
