Opportunities and Limitations in Achieving Real-Time Observation of Soil Nitrate

Creator:: Auld, Ryan A.
Abstract:: There are many possible benefits that can arise from the ability to take real-time measurements of soil water nitrate concentrations in a field, from ecological to agricultural to industrial reasons. In order to achieve this, we adapted a NitraLED sensor with a ceramic porous cup in order to allow diffusion...

Phytochemical characterization of Fagonia indica and its effects on MCF-7 breast cancer cell line

Creator:: Kumbi, Yadano
Abstract:: Phytochemicals from the genus, Fagonia, have been attracting increasing attention due to their potential beneficial effects on human health, particularly, anti-cancer properties. Certain Fagonia species contain various types of phytochemicals such as saponins, alkaloids, cardiac glycosides, flavonoids, terpenoids, and tannins. In this study, we investigated the phytochemical composition of a...

The Gut Microbiome Drives Benzo[a]pyrene's Impact on Zebrafish Behavioral Development

Creator:: Sieler, Michael J.
Abstract:: Benzo[a]pyrene (B[a]P) is a common environmental pollutant produced from the incomplete combustion of organic matter, such as fossil fuel emissions. In vertebrates, B[a]P exposure is associated with hyperactivity, though the underlying mechanisms driving this effect are undescribed. Mounting evidence indicates that the gut microbiome, which is the diverse community of...

Bacterial seed endophytes of Douglas-fir (Pseudotsuga menziesii) and their potential to confer drought tolerance

Creator:: Hatwal, Shikhar
Abstract:: Bacterial endophytes have the potential to confer benefits to Douglas-fir ( Pseudotsuga menziesii ), for instance drought tolerance. Bacterial endophytes originating from seeds are especially important. This is because seed endophytes are more likely to be the first endophytes to get established within the young host plant. The goals of...

Endometrial Inflammatory Cytokine Expression in Postpartum Beef Heifers Following Platelet Rich Plasma Treatment

Creator:: Perez, Victor O.
Abstract:: Background: Uterine inflammation (e.g., endometritis) causes negative economic effects in the beef industry by reducing reproductive performance. Current treatments for endometritis in beef cattle involve hormones and antibiotics, which can be expensive and are often ineffective. The endometrial immune response regulates the release of cytokines and chemokines in response to...

Impact of Polycyclic Aromatic Hydrocarbons on Barrier Function Toxicity in 3D Lung Model from Normal and Asthmatic Donor Cells

Creator:: Huynh, Celine T.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are known to cause adverse health effects in the human lung. Here, we evaluated biomarkers relevant for PAH toxicity in a 3D human primary bronchial epithelial cell (HBEC) model collected from normal and asthmatic donors. We previously found that PAHs decrease cellular barrier function integrity, which...

Functional consequences of microRNA regulation by polycyclic aromatic hydrocarbons in 3D human bronchial epithelial cells

Creator:: Mans, Michael-Andres D.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a class of contaminants ubiquitous in the environment and result from the incomplete combustion of fossil fuels. Many PAHs have been identified as procarcinogenic, and are metabolized to form DNA adducts; however, other mechanisms also may contribute to toxicity and help explain differences in toxicity...

Optimization of Schizochytrium limacinum SR21 Growth using Different Carbon Sources and Copper Concentrations

Creator:: Soo, Steven W.
Abstract:: The purpose of this project was to optimize the biomass growth of Schizochytrium limacinum SR21. This was achieved by studying the effect of various concentrations of glucose, use of pure glycerol and purified crude glycerol as alternative carbon sources, and inhibition of cell growth with the presence of copper. The...

The genetic diversity of Ceanothus-infective Frankia

Creator:: Ritchie, Nancy J.
Abstract:: Frankia from root nodules of nine different species of Ceanothus were characterized. DNA was amplified directly from nodular material using the polymerase chain reaction (PCR). The amplified region includes the 3' end of the 16S rRNA gene, the intergenic spacer (IGS), and a large portion of the 23S rRNA gene....

Mycobacterium tuberculosis Selective Adenosine Kinase Nucleoside Polymers for Inhalation Therapy

Creator:: Snow, Erika
Abstract:: Respiratory illnesses caused by both viral and bacterial infection are serious issues for global healthcare providers. With the emergence of new, drug-resistant forms of these diseases, innovative drugs and treatment therapies are needed. M tuberculosis is an infection that affects a large portion of the world’s population each year. Aerosol...
