Xanthohumol, a flavonoid from hops (Humulus lupulus) : in vitro and in vivo metabolism, antioxidant properties of metabolites, and risk assessment in humans

Creator:: Yilmazer, Meltem
Abstract:: Reported here is an investigation to determine the in vitro and in vivo metabolism of xanthohumol (XN). XN is the major prenylated flavonoid of the female inflorescences (cones) of the hop plant (Humulus lupulus). It is also a constituent of beer, the major dietary source of prenylated flavonoids. Recent studies...

Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

Creator:: Coblentz, Kyle E.
Abstract:: Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

Resource Type:: Dissertation
Full Text:: validate the temperature- phenology relationships of alfalfa. The percent advancement to first bloom per

Experimental taxonomy, 1930-1950 : the impact of cytology, ecology, and genetics on ideas of biological classification

Creator:: Hagen, Joel Bartholemew
Abstract:: During the years between 1930 and 1950 a number of attempts were made to introduce techniques and ideas from cytology, ecology, and genetics into the field of taxonomy. Advocates of this "experimental taxonomy" believed that cytological, ecological, and genetic techniques would provide a rigorous, objective methodology to replace the traditional...

Diverse consumer guilds in intertidal communities of Oregon and the Republic of Panama and their effects on prey assemblages

Creator:: Gaines, Steven D.
Abstract:: Low intertidal communities of Oregon and Panama have many predator and herbivore species. This diversity of consumers is important to the organization of both communities because of qualitative differences among the consumer species in their ability to circumvent specific prey defenses. In Oregon, the red alga Iridaea cordata is protected...

Structural effects of intrinsic and extrinsic perturbations to model membranes

Creator:: Church, Sara E.
Abstract:: The observed and calculated structural parameters of three systems of phosphatidylcholine bilayers in fully-hydrated multilamellar vesicles (MLVs) were determined using x-ray diffraction techniques. The analysis used the x-ray reflections from the low-, intermediateand wide-angle regions of the diffraction patterns in the subgel, gel, rippled and fluid phases to determine the...

Plant-Pollinator Interactions in a Changing World: Cryptic Specialization, Pollinator Movement, and Landscape Genetics of Pollinator-Dependent Plants

Creator:: Gannon, Dustin G.
Abstract:: Plant-pollinator mutualisms are one of the most prevalent and economically important mutualisms in nature. Like many other ecological systems, plant-pollinator communities are threatened by anthropogenic activity, both directly (e.g., habitat conversion and fragmentation) and indirectly (e.g., climate change). While we are aware of many of the activities that adversely impact...

Genetic variation in phenology of bud and cambial activity in coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco)

Creator:: Li, Peng, 1961-
Abstract:: Growth phenology (i.e., timing of growth initiation and cessation) is important to adaptation. This study examined the extent of genetic control of bud and cambial phenology and their relationships with stem growth in pole-size Douglas-fir (ages 13 to 16 years) from 60 open-pollinated families. The availability of bud phenology data...

Genetic variation and phenotypic stability among three elevational sources of coastal Douglas-fir from southwest Oregon

Creator:: Mangold, Robert
Abstract:: This study had three objectives: (1) to determine the degree to which within-source genetic variation and genetic correlations differ among elevational sources of Douglas-fir [Pseudotsuga menziesii (Mirb). Franco var. menziesii]; (2) to ascertain the degree to which phenotypic stability differs among and within elevational sources; and (3) to compare the...
