The Utilization Of Polymerase Chain Reaction, Dna Barcoding And Bioinformatics In Identifying Plant Species, Lindee J. Triplett, Ryan Foo, Ronald W. Strohmeyer (Mentor)

Idaho Conference on Undergraduate Research

Bioinformatics and DNA barcoding is a process used to identify plants, animals, and fungi. DNA barcoding in plants utilizes a key variable region in the genome, the RuBisCo large subunit (RbcL) on Chloroplast DNA. Once the DNA is extracted, Polymerase Chain Reaction (PCR) amplifies that region and that sample is sent off for sequencing. Bioinformatics and DNA barcoding helps taxonomists determine the sequence of the RbcL gene as well as obtain a unique barcode that can be used to identify plants. Several plant species from our local campus were sequenced and identified using the previously described methods.

Speciation In Western North America: Lomatium As An Example Of Diversification And Convergent Evolution, Edgar M. Sosa, Lauren Polito, Mckayla Stevens, Donald H. Mansfield, James F. Smith (Mentor)

Idaho Conference on Undergraduate Research

Species delimitations and understanding the processes that drive speciation are essential to nearly all aspects of human endeavor. Determining species boundaries traditionally used morphology. Phylogenetic analyses based on DNA sequence data provide a means to resolve species boundaries, as well as test hypotheses regarding the evolutionary processes. Numerous species radiations have occurred in Western North America. Among these are several plant groups such as Astragalus, Artemisia, and Lomatium. Recent phylogenetic analyses of Lomatium and related genera have demonstrated that many of the morphological characters used to delimit taxa have arisen multiple times and that most taxa are para- …

Maternal Prenatal Depression And Anxiety Affect Neonatal Neurobehavior, Shelby Siddall, Jason Gibbs, Aimee Martin, Nicki Aubuchon-Endsley (Mentor)

Idaho Conference on Undergraduate Research

Prenatal depression and anxiety have been linked to impaired infant neurobehavior including altered attention, responsivity, and quality of movement. No known studies have assessed individual and joint effects of prenatal depressive and anxiety on neonatal neurobehavioral outcomes. The current study compared these outcomes among (1) mothers diagnosed with comorbid Depressive and Anxiety Disorders, (2) mothers diagnosed with only Depressive Disorders, (3) mothers diagnosed with only Anxiety Disorders, and (4) mothers with no prenatal diagnosis.

Maternal prenatal diagnoses were assessed by the SCID-I. Offspring neurobehavior was assessed from 1-2 to 30 days using the NNNS. There was a between-subject's effect ( …

Total Synthesis And Derivation Of Humulones And Lupulones As Possible Biologically Active Agents, Lucas R. Sass, Kristopher V. Waynant (Mentor)

Idaho Conference on Undergraduate Research

Humulones and lupulones have affirmed themselves as key ingredients in the multi-billion dollar brewing industry. Originally exploited for their bacteriostatic properties, these compounds also exhibit high levels of biological activity against a variety of diseases. Although quantifiable, the isolation and separation of specific humulones and lupulones has proven difficult, thus establishing efficient synthetic routes will be of value to those desiring exact bittering qualities and to the pharmaceutical community. Our investigations are towards developing a synthetic route to a library of humulones, lupulones, and their derivatives as possible biologically active agents against myriad diseases. The key step in our efficient …

Integrity Coded Databases (Icdb) - An Evaluation Of Efficiency, Performance, And Practicality, Jake Rodden, Jyh-Haw Yeh (Mentor), Elmer Duran, Dan Kondratyuk

Idaho Conference on Undergraduate Research

Recently, cloud database storage has become an inexpensive and convenient option to store information; however, this relatively new area of service can be vulnerable to security breaches. Storing data in a foreign location requires the owner to relinquish control of their information. This opens the possibility for internal, malicious attacks that can involve the manipulation, omission, or addition of data. Our research tests a potential solution for retaining data as it was intended to be stored (known as integrity) in these cloud-stored databases: by converting the original databases to Integrity-Coded Databases (ICDB). ICDBs utilize Integrity Codes: cryptographic codes created for …

The Future Of Rural Communities, Alondra B. Perez, Yanliang Zhang (Mentor)

Idaho Conference on Undergraduate Research

There is a problem in how modern energy is being distributed throughout the world; less than a quarter of the population have access to energy. Limited energy access is seen in rural areas because of the costs that comes from transporting material and making modern energy resources (solar panels, wind turbines, etc..). Through research on thermoelectric devices, there have been many theories tested in order to improve energy efficiency focusing on easy maneuverable resources. At Boise State’s Advanced Energy Lab, thermoelectric generators are being created and modified which can be used to help communities from rural areas power utilities needed …

Photosynthetic Capacity Within The Phantom Gas Field Project, Traci L. Olson, Maria Pacioretty, Keith Reinhardt (Mentor)

Idaho Conference on Undergraduate Research

Anthropogenic noise has proven detrimental to organisms like bats, owls, and certain other species whose hunting or navigation success is affected by unnatural sound. However, few studies have quantified the effects of noise pollution across multiple trophic levels. Our study is quantifying the impacts of human noise on insect abundance and herbivory, and plant physiology, using experimental noise stations compared to quiet control sites in the sagebrush steppe southwest of Boise, Idaho. I am measuring variation in leaf chlorophyll fluorescence and Normalized Difference Vegetation Index (NDVI). Both of these measurements are indirect measurements of photosynthetic capacity. We hypothesized that shrubs …

Investigations Into The Modification Of Dna By Doxorubicin Analogs, Hannah Kulm, Stephanie Torres, Chris Mallory, Kenneth Cornell (Mentor), Don Warner (Mentor)

Idaho Conference on Undergraduate Research

Doxorubicin (DOX) is an anthracycline chemotherapeutic that has seen widespread use to treat numerous cancer types. Its mechanism of action is still unclear, but is thought to include the intercalation of DNA, halting transcription and inducing apoptosis. Although DOX has shown strong antitumor activity, its usage is limited due to a dose-dependent onset of cumulative and irreversible life-threatening cardiac damage. Consequently, the harmful side effects necessitate the need for the production of new, less harmful anthracycline chemotherapeutics with greater effectiveness for the treatment of cancer. Three analogs of DOX (P-DOX, GPX-150 and GPX-160) have been synthesized and determined to have …

Cryptographic hash functions have many applications in information security and are commonly used to verify data authenticity. Our research focuses on the study of the properties that dictate the security of a cryptographic hash functions that use Even-Mansour type of ciphers in their underlying structure. In particular, we investigate the algebraic design requirements of the Grøstl hash function and its generalizations. Grøstl is an …

Interactions Between Maternal Prenatal Obesity And Physiological Stress: Predictors Of Offspring Adult Obesity, Jennifer L. Hambleton, Jared Vineyard, Nicki L. Aubuchon-Endsley (Mentor)

Idaho Conference on Undergraduate Research

Over half of US women of childbearing age are overweight or obese. This is significant because excessive gestational maternal weight may program offspring for greater risk of lifetime obesity. Preliminary research suggests this effect may be moderated by fetal exposure to stress hormones, known to be dysregulated in obese individuals. However, long-term longitudinal research of these constructs is needed.

Therefore, this study used archival data from the NEFS/CPP Studies to examine interactions between maternal pre-pregnancy BMI/gestational weight gain and fetal cortisol exposure as predictors of offspring growth trajectories from birth-7 years and adult BMI via growth curve modeling and ANOVAs. …

First-Generation College Students, Identity, & Empowerment Labels, Curtis Green-Eneix, Dr.Gail Shuck (Mentor)

Idaho Conference on Undergraduate Research

First-generation college students (FGCS) have been the primary focus of college retention research due to more FGCS entering universities, and FGCS’s low retention rates. Recent research has focused on quantitative studies of FGCS from comparing education and social backgrounds to non-FGCS, to outside constraints FGCS face while in college. These findings result in general understandings of FGCS dealing with additional hardship to moments of severe loneliness. This study explores (1) how FGCS—from Boise State University’s Student Success Program (SSP)—perceive their identity in a college community, (2) how they have or have not experienced identity conflicts while pursuing a degree, and …

Sex Differences In Placental Epigenetic Regulation Of Leptin Hormone Are Associated With Elevated Maternal Gestational Weight Gain, Nicole E. Douthit, Nicki Aubuchon-Endsley Ph.D. (Mentor)

Idaho Conference on Undergraduate Research

In utero epigenetic factors affect health and development, though sex differences in epigenetic effects of prenatal maternal health may exist for placental hormones. Specifically, maternal prenatal obesity affects expression of placental leptin hormone genes, which play a unique role in metabolism and appetite. However, the effects of such expression on infant neurobehavioral development differ by offspring sex.

Therefore, we examined sex differences in the effects of maternal gestational weight on placental leptin gene methylation. Data (n=155) were taken from the Behavior and Mood in Mothers and Behavior in Infants Study. Maternal pre-pregnancy weight was self-reported, while delivery weight …

Nanostructured Polymer Lithography For Photovoltaic Applications, Allison J. Christy, Nicholas L. Mckibben, Jerry D. Harris (Mentor), David Estrada (Mentor)

Idaho Conference on Undergraduate Research

The self-assembly of diblock copolymers into ordered domains holds great potential to furthering the efficiency of photovoltaic devices. Solutions containing polystyrene-block-poly(ethylene oxide) (PS-b-PEO) and poly(methyl methacrylate) (PMMA) were applied to silicon wafers from toluene solutions. Hexagonally ordered domains, with pore sizes ranging from 10-30 nm, were obtained by annealing films in solvent vapor, with the best results produced from a humidified benzene environment. Exposing the films to UV light cross-linked the polystyrene matrix and degraded the PMMA. Removal of the PMMA and PEO produced an ordered polystyrene template, which can be used for nanolithography for the …

The Linguistic Features Of Deceptive Speech, Jared Albrecht, Michal Temkin Martinez (Mentor)

Idaho Conference on Undergraduate Research

Research on deception within the field of linguistics has been largely focused upon the lexical aspect of lies. However, while the words a liar uses may reveal the lie in some cases, there are certain prosodic features of speech (e.g. pitch or tempo) that may be correlated to lying. This study focuses on these features in an attempt to decode deception. In an experiment with a representative sample of a university campus population, participants were asked to lie for science in a game of ‘Two Truths and a Lie’. Each participant’s speech was recorded while they constructed spontaneous truths and …
