Oil Preference In Ants And Arthropod Diversity In Urban Environments, Itzel Guzman-Hernandez 2019 University of Tennessee at Chattanooga

Oil Preference In Ants And Arthropod Diversity In Urban Environments, Itzel Guzman-Hernandez

Honors Theses

The success of certain ant species in urban areas is largely unknown. Available food in the environment could affect the composition of ants in urban areas due to a possible relationship between ant physiology and diet. I tested the oil preference of ants as a function of available arthropod prey in urban environments. I hypothesized that as arthropod diversity decreased, ant abundance at oil baits would decrease. Oil is an important nutrient that can affect ant body functions and activities. Ant foraging activities have been found to be affected by lipid depletion. A food source where ants can obtain oil ...

Eared Grebe Nesting Ecology And Chronology Along The Great Salt Lake, Utah, Leah M. Delahoussaye 2019 Utah State University

Eared Grebe Nesting Ecology And Chronology Along The Great Salt Lake, Utah, Leah M. Delahoussaye

All Graduate Theses and Dissertations

Eared Grebes (Podiceps nigricollis) are migratory birds that build their nests over water and in large groups called colonies. Their typical breeding range is in central southern Canada and northern United States; however, a previously uncertain number of Eared Grebes (grebes) also nest around the Great Salt Lake (GSL), Utah, at the southern edge of their breeding range. Little is known about the habitat requirements for grebe nesting colonies at such low latitudes and if they are different from colonies found elsewhere. My objectives for this research were to determine the status of the grebe nesting population as well as ...


Analysis Of Sublethal Toxicity In Developing Zebrafish Embryos Exposed To A Range Of Petroleum Substances Using Be-Spme And Whole Transcriptome Microarray, Bryan Matthew Hedgpeth 2019 Seton Hall University

Analysis Of Sublethal Toxicity In Developing Zebrafish Embryos Exposed To A Range Of Petroleum Substances Using Be-Spme And Whole Transcriptome Microarray, Bryan Matthew Hedgpeth

Seton Hall University Dissertations and Theses (ETDs)

The OECD 236 Fish Embryo Acute Toxicity Test guideline relies on four endpoints to describe exposure related effects (coagulation, lack of somite formation, tail-bud detachment from yolk-sac, and presence of heartbeat). Danio rerio (zebrafish) embryos were used to investigate these endpoints along with a number of additional sublethal effects (i.e. cardiac dysfunction, pericardial edema, yolk sac edema, tail curvature, hatch success, pericardial edema area, craniofacial malformation, swim bladder development, fin development, and heart rate) following five day exposures to one of seven petroleum substances. The substances investigated included two crude oils, three gas oils, a diluted bitumen, and a ...

Does Tcdd Exposure Alter Β7-Integrin Expression On Mouse B Cells?, Sebastian Ramos 2019 University of Northern Colorado

Does Tcdd Exposure Alter Β7-Integrin Expression On Mouse B Cells?, Sebastian Ramos

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Activated aryl hydrocarbon receptor with ligand 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) alters immune responses, including immunoglobulin A (IgA). Manipulation of antibody production via this ligand-activated receptor may provide a novel approach to enhance vaccination in the intestines. The present study aimed to explain the mechanism responsible for increased levels of fecal IgA in TCDD-treated mice. We hypothesized that TCDD enhances migration of B cells from non-intestinal tissue to the intestines. Here we predicted that β7-integrin, an essential protein for B cell migration into the intestines, would be upregulated by TCDD exposure on B cells. Female C57BL/6 mice were treated ...

Trefoil Factor 1 (Tff1) Expression In E3 And Ewd8 Breast Cancer Cell Lines, Jazmyn Mosqueda-Banuelos

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

The ability to identify and treat cancer early can drastically improve patient survival outcomes. While much effort is placed on anti-cancer therapeutics, a developing area of interest is the identification of cancer biomarkers for the early detection of different types of cancer. Trefoil factors (TFFs) are a family of proteins whose known functions suggest that they may be major contributors to cancer; however, these proteins are understudied in a disease state like cancer. In this work, we identify expression of TFF1 among varying cancer types. We then investigate the correlation between varying levels of TFF1 expression and the aggressiveness of ...


Investigating The Antidiabetic Effect Of Metformin On Pyruvate Carboxylase, Guadalupe A. Solis 2019 University of Northern Colorado

Investigating The Antidiabetic Effect Of Metformin On Pyruvate Carboxylase, Guadalupe A. Solis

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Metformin is the most commonly prescribed treatment for type II diabetes. While the clinical effects of this generic drug are established, exact targets of metformin action remain unclear. The hypothesis of the present study was that metformin lowers blood glucose through inhibition of pyruvate carboxylase (PC), an enzyme catalyzing the first committed step of gluconeogenesis. Because metformin is relatively low cost, it is widely accessible to communities worldwide; currently, 150 million individuals depend on metformin for treatment. Thorough investigation of all targets involved in action of metformin becomes crucial, as it further explains the adverse effects of the drug. The ...

Amino-Terminal Sequencing Of Ssv1 Major Capsid Protein Vp1 Mutants, Nichole D. Procter, Kenneth M. Stedman, Ignacio de la Higuera, George Kasun, Ajay Sapre 2019 Portland State University

Amino-Terminal Sequencing Of Ssv1 Major Capsid Protein Vp1 Mutants, Nichole D. Procter, Kenneth M. Stedman, Ignacio De La Higuera, George Kasun, Ajay Sapre

Student Research Symposium

Unique lemon-shaped viruses, the Fuselloviridae, or Sulfolobus Spindle-Shaped Viruses (SSVs) of hyperthermophilic archaea are characterized by both their unusual structure and extreme thermal tolerance. The most well characterized of the SSVs is SSV1. Wild-type SSV1 tolerates multiple mutations to its genome while still remaining infectious, making this virus ideal to study molecular processes in extreme environments. The major capsid protein, VP1 forms the unique structure of the virus and provides protection for the genome. The amino terminus of the VP1 protein purified from wild-type SSV1 is glutamate 66 (E66) indicating proteolytic cleavage. E66 is universally conserved in all SSVs. Interestingly ...

Effects Of Treatment On Melanoma With Checkpoint Inhibitor, Pembrolizumab (Keytruda ®), Anti-Cd47 Tti-621 (Trillium), And Anti-Sema4d Pepinemab Combination Treatment, Lauren E. Fitzgerald

Seton Hall University Dissertations and Theses (ETDs)

Traditionally, cancer therapies are generally non-specific treatments meant to eradicate cancer cells. This can result in death of healthy tissue, which can significantly affect the overall well-being of the patient during and after treatment. Immunotherapy offers a more targeted approach by using immune cells to specifically identify and kill cancer cells through various neoantigens presented on the surface of the cancer cell. Drugs that target and block PD-(L)1 and CTLA-4, known as checkpoint inhibitors, act to “cut the breaks” on the immune response and keep it actively seeking out and killing cancer cells. Many patients fail on these ...

Cd4 + Th1 Helper Cells: The Unifying Link Between Diabetes And Periodontitis, Jocelyn Stewart

BIO 410 Spring 2019 Research Papers

Type II diabetes and Periodontitis are both chronic inflammatory diseases that affect people worldwide. Periodontitis is characterized by the obliteration of teeth. It affects 10-15% of adults and causes many problems on the quality of life (Preshaw et al., 2012). Diabetes is a disease that arises when your blood sugar is too high. Your blood glucose is the primary source of energy which is consumed by the food you eat. The hormone insulin is produced by the pancreas, which helps the glucose from allowing food to enter your cells. Many studies have shown that type 2 diabetes is a major ...


Aluminum Adjuvants In Vaccines: Movement Towards Understanding Their Role And Mechanism Of Action, Thad Rehmert 2019 Lincoln University

Aluminum Adjuvants In Vaccines: Movement Towards Understanding Their Role And Mechanism Of Action, Thad Rehmert

BIO 410 Spring 2019 Research Papers

Aluminum adjuvants have been used in vaccines for over 80 years in order to increase the immune response in vaccinated individuals. While the addition of aluminum adjuvants has been extremely successful, the success powered the adjuvants to be used in numerous vaccines without a proper understanding of their mechanisms of action. Advancements in medical understanding over the last 4-5 decades has resulted in researchers understanding the harsh reality of aluminum toxicity. Due to this, researchers have begun to delve into the actions and mechanisms of these adjuvants in an effort to enhance understanding of how they work. This review will ...


Tissue-Engineered Grafts: The Future Of Anterior Cruciate Ligament Reconstructive Surgery, Amber Braxton 2019 Lincoln University

Tissue-Engineered Grafts: The Future Of Anterior Cruciate Ligament Reconstructive Surgery, Amber Braxton

BIO 410 Spring 2019 Research Papers

Anterior cruciate ligament (ACL) ruptures are common injuries, specifically for young athletes, and in order to repair this injury, the patients must undergo ACL reconstructive surgery. This surgery commissions the use of autografts and allografts in order rebuild the torn ligament. Traditional autografts are the patellar tendon autograft, which is the most common, and the hamstring autograft. These grafts are made by transplanting tissue from the patellar tendon or the hamstring to the ruptured ACL. Allografts are another type of graft that involves transplanting tissue from a donor cadaver to the patient. Traditional autografts and allografts have been used for ...


Type-I Prenyl Protease Function Is Required In The Male Germline Of Drosophila Melanogaster, Katie Adolpsen, Amanda Amell, Nathan Havko, Sara Kevorkian, Kyle Mears, Dietmar Schwarz, Sandra R. Schulze 2019 Western Washington University

Type-I Prenyl Protease Function Is Required In The Male Germline Of Drosophila Melanogaster, Katie Adolpsen, Amanda Amell, Nathan Havko, Sara Kevorkian, Kyle Mears, Dietmar Schwarz, Sandra R. Schulze

Sandra R. Schulze

Many proteins require the addition of a hydrophobic prenyl anchor (prenylation) for proper trafficking and localization in the cell. Prenyl proteases play critical roles in modifying proteins for membrane anchorage. The type I prenyl protease has a defined function in yeast (Ste24p/Afc1p) where it modifies a mating pheromone, and in humans (Zmpste24) where it has been implicated in a disease of premature aging. Despite these apparently very different biological processes, the type I prenyl protease gene is highly conserved, encoded by a single gene in a wide range of animal and plant groups. A notable exception is Drosophila melanogaster ...


Chronic Wasting Disease Management Through Culling, Baiting, And Vaccination Methods, Jake Brockman 2019 Lincoln University

Chronic Wasting Disease Management Through Culling, Baiting, And Vaccination Methods, Jake Brockman

BIO 410 Spring 2019 Research Papers

Chronic wasting disease (CWD) is a lethal, progressive, and highly infectious disease that targets cervid populations through transmission by prions. There are currently no treatment options that are highly effective at stopping CWD, but the scientific community has great knowledge on CWD’s transmission and effects. In this literature review: culling, baiting and vaccination techniques are analyzed and compared to view which method could potentially work the best to control CWD. Long term effects of CWD could result in cervid population extermination and enormous economic losses for areas that are inhabited by cervids.

Silkworm silk has become increasingly relevant for material applications. However, the industry as a whole is retracting because of problems with mass production. One of the key problems is the inconsistent properties of the silk. A means by which to improve the silk material properties is through enhanced sericulture techniques. One possible technique is altering the feed of the silkworms to include single-wall carbon nanotubes (SWNTs) or graphene (GR). Recently published results have demonstrated substantial improvement in fiber mechanical properties. However, the effect of the surfactant used to incorporate those materials into the feed on the fiber mechanical properties in ...
