Probing Circadian Clock-Steroid Receptor Interactions in GnRH Neurons

Creator:: Grimwood, Victoria J.
Abstract:: Endogenous circadian clock regulation is essential to normal rhythmicity, particularly the timing of hormone release in the brain. In the context of mammalian reproduction, a surge of a specific hormone, gonadotrophin-releasing hormone (GnRH), initiates a surge of luteinizing hormone (LH) from the pituitary gland, which is required for ovulation in...

Survey of rhizosphere associated entomopathogenic fungi on small fruits and Christmas trees in the Willamette Valley, OR

Creator:: Fisher, Joanna J.
Abstract:: The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana are commercially available as microbial control agents for the black vine weevil, Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae), the key root-feeding insect pest in Pacific Northwest small fruits and ornamentals. Understanding habitat selection is critical to improve the efficacy, persistence and cost of...

Light quality manipulation for the solvent extraction of phycocyanin from Oregon freshwater cyanobacteria

Creator:: Gregor, Katelin
Abstract:: Phycocyanin, a photosynthetic pigment-protein complex produced by cyanobacteria, has critical value in the medical field at high purity. Costs associated with the extraction of this pigment are high, emphasizing the importance of optimal growth conditions. The aim of this study was to investigate potential commercial producers of phycocyanin by evaluating...

Automated annotation of Caenorhabditis mitochondrial genomes and phylogenetic analysis

Creator:: Campbell, Jessica L.
Abstract:: Motivation Relatively little is known about the evolution of mitochondrial genomes between Caenorhabditis species despite decades of research. Both the worldwide search for new nematode species and the effort to increase sequencing speeds require automated tools to quickly characterize and categorize large amounts of data. Results We developed an automated...

Superior Anti-tumor Activity Exhibited From a Gemcitabine Prodrug Incorporated into Lecithin-Based Nanoparticles

Creator:: Sandoval, Michael
Abstract:: Cancer is class of diseases that has great diversity and unfortunately is one of the leading causes of death in the United States. Chemotherapy remains an important cancer treatment modality, and superior chemotherapeutic drugs are constantly being sought. Gemcitabine is an anti-tumor chemotherapeutic drug and it is the first line...

Response of reef fish assemblages to overgrowth of the hydrocoral Millepora complanata by the crustose alga Ramicrusta sp.

Creator:: Adams, AnnaRose
Abstract:: Natural disturbances and human activities can alter the benthic composition of coral reefs and other marine ecosystems. Reef fishes that associate with particular structures on the sea floor, such as coral heads, may be vulnerable to perturbations of those habitats. The spread of a newly discovered crustose alga (Ramicrusta sp.)...

Anti-Mullerian Hormone (AMH) Levels Are Reduced by Age, But Do Not Correlate With Pregnancy In Timed-Mated Rhesus Monkey Females (Macaca mulatta)

Creator:: Roth, Maggie
Abstract:: Infertility is an issue affecting millions of women across the globe, yet the causes are not fully understood, and treatment options are often ineffective. The evaluation of reproductive hormones has been a common tool used by fertility clinics as a way to predict the ovarian response to treatment and gain...

Guinea pig model of mild hyperandrogenemia – is it a suitable model for women with polycystic ovary syndrome (PCOS)? A pilot study

Creator:: Barboza Sagrero, Juriana E.
Abstract:: Polycystic Ovary Syndrome (PCOS) is an idiopathic disorder prevalent in ~5-10% of reproductive-aged women. In PCOS women who become pregnant, many experience complications including increased susceptibility of having a miscarriage, high blood pressure, and gestational diabetes, among others. Additionally, exposure to PCOS may have transgenerational impacts: offspring may be at...

Inhibition of α-Amylase and α-Glucosidase by Bioflavonoids

Creator:: Griffith, Anneke M. (Tucker)
Abstract:: Various flavonoid-rich plant extracts have shown efficacy in the treatment of diabetes. Although it is often assumed that dietary flavonoids exert biological antioxidant effects, it is possible that the observed effects work in carbohydrate metabolism. In this study we evaluated the effect of catechins and catechin containing extracts on α-amylase...

VOC Emisions and Categorization in Axenic Growth Conditions by Phaeodactylum tricornutum

Creator:: Thompson, Douglas A.
Abstract:: Volatile organic compounds (VOCs) play an integral role in climate change and as a carbon source for organisms living in a marine environment. These compounds have many sources, but the impacts of biogenically produced VOCs is not fully known. Phaeodactylum tricornutum was studied under axenic ideal growth conditions to determine...
