Evaluating Volatile Organic Compounds For Contact-Independent Antagonism Of Pseudogymnoascus Destructans

Symposium of Student Scholars

White-nose syndrome (WNS), a disease caused by the fungus Pseudogymnoascus destructans, is responsible for the extensive mortality of bats in the United States. In an effort to develop tools to reduce bat mortality attributed to WNS, an in vitro experiment was conducted to quantify the inhibitory effects of select volatile organic compounds (VOCs) as well as explore potential synergistic activities. The experiment involved exposing mycelial plugs of P. destructans to various concentrations of B23 as well as B23 and decanal together at equimolar ratios. Measurements of the plugs were taken over the course of the 13 day experiment allowing …

P-19 Anticancer Activity Of Heteroaromatic Cyanostilbenes, Joshua Rotich

Celebration of Research and Creative Scholarship

Cancer is currently the second leading killer disease. There are many different kinds of cancer that are associated with almost every organ in the human body (e.g., brain cancer, colon cancer, breast cancer, prostate cancer, blood cancer, lung cancer, etc.).

In the Biology Department, Dr. Smith and Dr. Murray are researching glioblastoma brain cancer cells. Glioblastoma is a very invasive cancer that is highly lethal. Chances of not surviving when its at stage four is more than 98%. Detecting this cancer while it is developing is difficult because symptoms are mild headache, fatigue, nausea and slight loss of weight. By …

Stable Nanopalladium Hydride In Water For Sustainable And Selective Reductions, Jesse Klus, Sachin Handa

Posters-at-the-Capitol

The synthesis of air-stable ligand-free nanopalladium hydride (PdNHx) in water was achieved and applied to various organic transformations, including (1) reduction of heteroaromatics such as (iso)quinolines, phenanthrolines, benzotriazole, and naphthyridines, (2) regio- and chemoselective reduction of nitroarenes, (3) alkyne reductions, (4) chemoselective dehalogenation, and (5) base-free detriflation. Both the synthesis of PdNHx and the reductions were carried out under mild conditions in a micellar medium using our designer surfactant PS-750-M, which eliminates the need for toxic organic solvents and extremely high hydrogen pressure and temperature. Notably, PS-750-M is also a replacement of hazardous polar-aprotic solvents. This newer approach for selective …

The Wet Bridge Transfer System: An Novel In Vitro Tool For Assessing Exogenous Surfactant As A Pulmonary Drug Delivery Vehicle, Brandon J. Baer

Western Research Forum

Background:

Due to its complex branching structure, direct drug delivery to the remote areas of the lung is a major challenge. Consequently, most therapies, such as those treating pulmonary infection and inflammation, must utilize large systemic dosing, with the potential for adverse side effects. A novel alternative strategy is to use exogenous surfactant, a material capable of distributing throughout the lung, as a pulmonary drug delivery vehicle.

Objective:

Utilize an in vitro transferring system to assess exogenous surfactant (BLES) as a pulmonary delivery vehicle for different therapeutics.

Methods:

An in vitro technique was developed to simultaneously study surfactant delivery and …

Using Molecular Dynamics To Study Qs21 Interactions And Penetration Of Lipid-Cholesterol Bilayers, Sarai Guerrero, Mikko Karttunen

Western Research Forum

Saponins have been used as adjuvant agents for decades in vaccines and therapies, but none are as well studied or heavily used as QS-21. This achievement is notwithstanding the fact that QS-21 usage is limited by its stability, toxicity, and scarcity. These shortcomings have only pushed researchers to develop and experiment with artificial recreations of the saponin to harness its unique benefits. A considerable number of research hours have been poured into this topic, but like QS-21 there is a shortcoming here as well. The number of articles that look at QS-21 interactions with the bilayer or the conditions under …

Rowan-Virtua Research Day

Invasive fungal infection has a significant prevalence among organ transplant patients and is associated with high rates of morbidity and mortality. Fungal infection is difficult to identify early and subsequently difficult to effectively treat. In this case presentation we have a 45 y/o orthotopic liver transplant recipient who was profoundly sick from fungal peritonitis and due to the appearance of her abdomen and intestines, with the help of infectious disease, decided to proceed with direct amphotercin washout of the abdomen in the operating room. The patient had complete resolution of her fungal peritonitis and is doing well.

Retrospective Analysis On The Susceptibility Of Opiate Addiction Based On Prescribed Medications And Chronic Pain Diagnoses, Momna Ayub, Richard Jermyn D.O.

Rowan-Virtua Research Day

Introduction: Opioid medications have been increasingly prescribed in recent years, particularly to treat individuals with chronic pain. In the U.S., opioid abuse has been declared an epidemic by the Department of Health and Human Services as the number of opioid-related overdoses in 2010 exceeded 16000 and alarmingly continued to rise 15% from 2015 to 2016. Due to opioid dependence and abuse, opioids are a gateway to subsequent drug addiction.

Objective: The goal of this project was to identify a link between certain prescribed opiates and a susceptibility for abuse or misuse in patients with chronic pain through a retrospective analysis. …

Rowan-Virtua Research Day

Amiodarone has a well-established and extensive side effect profile: pulmonary fibrosis, thyroid toxicity, corneal deposits, skin discoloration. However, in some rare instance, epididymitis/orchitis is a side effect of amiodarone. Amiodarone toxicity was first studied in (1, 2) Symptoms range from testicular pain to swelling and erythema (1,2) The mechanism of how this toxicity occurs is unknown. In this case report, we will discuss the case of an elderly patient who developed epididymitis and orchitis after several years of tolerating amiodarone without any adverse events. Our patient underwent a full workup with testicular ultrasound, evaluation by urology and cardiology specialists. Then …

The Effects Of Antenatal Betamethasone On Late Preterm Infants, Jennifer Hummel D.O., Abigail Prest D.O., Xinhua Chen M.D.

Rowan-Virtua Research Day

Administration of steroids to mothers expected to deliver in the late preterm period has previously been found to decrease neonatal respiratory morbidity. In this retrospective chart review, there were no significant differences between groups in the primary outcome of required respiratory support for the neonate, incidence of periventricular hemorrhage or neonatal death. However, this study found that their rate of hyperbilirubinemia, need for phototherapy, and NICU stays were longer than their counterparts whose mothers did not receive steroids or who only received one dose.These findings may provide support for future protocols directed to improve neonatal morbidity secondary to jaundice.

The Effect Of Omm On Opioid Users With Chronic Low Back Pain, Danielle Cooley D.O., James Bailey D.O., Deanna Janora M.D., Catherine Fusco D.O., Kishan Patel

Rowan-Virtua Research Day

In the United States, approximately 100 million adults are affected by chronic pain, which reduces their quality of life and productivity, while accounting for billions in health care costs and lost revenue. (1) Opioids are considered the gold standard in the pharmacological treatment for chronic pain conditions, and prescriptions for opiates/opioids increased by 400% from 1999 to 2010. (1,2) Although opioid treatment is warranted during postsurgical and active cancer pain, physicians still commonly overprescribe opioids, which has led to addiction, high deaths rates by overdose, and the spread of communicable diseases. (1)

Since chronic pain is sustained by noxious sensory …

The Teen Vaping Crisis, Jayavignesh Ganesan '21, Cynthia Mu '21, Carolina Seoane '21

Student Leadership Exchange (SLX)

In today’s society, many teens have the idea that is is cool to vape. This has led to an exponential increase in the number of teenagers addicted to nicotine. This increase is directly caused by nicotine companies, specifically vape companies, presenting their products with appealing and misleading packaging. Indeed, nicotine packages are required to have a warning. However, the warning is usually not taken into consideration, as the warning is not eye-catching. Because of this, we propose that all products containing nicotine, including e-cigarettes, must follow plain packaging regulations. Under plain packaging regulations, companies would be required to have the …

Synthesis Of A Zn(Ii)-Responsive Paracest Mri Agent For Improved Diagnosis Of Prostate Cancer, Megan Martin, Holly Clancy

Creative Activity and Research Day - CARD

In the United States, prostate cancer is the leading type of cancer diagnosed in men. Prostate cancer is currently diagnosed with the Prostate-Specific Antigen (PSA) test; however, it leads to many false positives and therefore unneeded biopsies. Previous studies have shown that cancerous prostates have a much lower concentration of zinc than healthy prostates. The goal of this project is to create an MRI contrast agent capable of non-invasively quantifying zinc in the human prostate. Five out of the eight synthetic steps have been successfully completed so far, and the identities of these intermediate products have been verified by ^{1 …}

Impact Of Quinoline Amide Substituents On The Luminescence And Paracest Mri Properties Of Bimodal Europium (Iii) Complexes, Brooke Aloe, Marisa Poveda, Osasere M. Evbuomwan

Creative Activity and Research Day - CARD

Lanthanide ions exhibit optical imaging properties; however, the amount of energy needed to directly excite these ions could potentially be damaging to biological tissue. To overcome this limitation, organic chromophores, such as quinolines, can be used to absorb the excited light and transfer the energy obtained to the attached lanthanide ion. This intramolecular energy transfer results in the sensitization of the lanthanide ion luminescence. The goal of this project is to assess how the amide proton position in relation to the quinoline substituent affects the sensitivity of luminescence and the optical imaging properties of Europium (III) complexes. To achieve this …

Effect Of Salt Concentration On Electrochemical Detection Of Dna, Ziming Dong, Eddie Madrigal, Ryan West Dr.

Creative Activity and Research Day - CARD

Electrochemical approaches for biological sensing offer the potential advantages of facile sample preparation, fast response times, ease of parallel and multiplexed measurements, and the possibility of miniaturization (of sample sizes, electrodes, and associated electronics). All of these factors contribute towards the feasibility of electrochemical methods in biological sensing and analysis. This potential has already been achieved with the commercialization of blood glucose meters, which often rely on an electrochemical transduction mechanism. We have previously demonstrated the ability to electrochemically detect and differentiate complementary and mismatched DNA using our method of melting DNA duplexes at electrified gold surfaces, i.e. e-melting. Recently, …

Chemophobia And The Relation To Names, Justin Crow

Undergraduate Research Conference

Chemophobia is a recently identified cultural phenomena where people are afraid of chemicals in their lives, whether "chemicals" are in their food, their medicines, vaccinations, and other products. An increasing amount of people have a concern about the risk associated with chemicals in their everyday life. Chemistry professionals find this a bit strange as Chemistry states that all matter is made up of chemicals. Chemistry has many systems of naming and understanding chemicals which can exclude people from understanding the risk or lack thereof attributed to materials that are common in daily life. This effect could be accentuated by educational …

Adhd Medication: To Medicate Or Not To Medicate?, Alyssa Henderson

Undergraduate Research Conference

Eleven percent of American children are diagnosed with at least one type of ADHD. That is 6.4 million children that are clinically diagnosed with the inability to focus attentively, restlessness, imbalanced mood swings and under-developed social skills. All of these lead to any learning environment being a daily battleground in the children both internally as well as externally. This is caused due to an under-activity in the frontal lobe of the child’s brain, which is responsible for their planning, motivation, social behavior and speech production. The symptoms associated with ADHD are currently being combated with the utilization of stimulants known …

Peptide Functionalized Surfactant Msns, Sonia Barrett

Kansas State University Undergraduate Research Conference

Antibiotic resistance in bacteria has become a rising problem since the first antibiotic was created, further aggravated by the improper overuse to treat common infections, because of this pharmaceutical companies must keep making new and stronger antibiotics. Surfactants are plentiful and effective killers of many surface bacteria and are also varied in their structure, all have a hydrophilic head and long hydrophobic carbon chain. These long hydrophobic carbon chains can pierce through the lipid bilayers that make up bacteria cell membranes and cause cytoplasmic leakage and lysis of the cell wall, leading to cell death. One proposed surfactant is synthesized …

Peptide Conjugation Of Branched Amphiphilic Peptide Capsules, Baltazar Claro-Martinez

Kansas State University Undergraduate Research Conference

In recent years, nanocarrier cellular therapy has been a rapidly growing area for research in the treatment of malignant and infectious diseases – most notably cancer. Conventional cancer treatment has consisted of highly toxic, highly insoluble, untargeted delivery of drugs that kill both cancerous and healthy cells. Research in the Tomich lab consists of the synthesis of Branched Amphiphilic Peptide Capsules (BAPCs), which are self-assembling peptide nanospheres composed of one or both of these branched peptide sequences: h5 and h9. These peptides possess similar molecular characteristics of phosphoglycerides but are synthesized chemically within the lab. Previous publications by the Tomich …

Cancer occurs when a mutated single cell continues to divide uncontrollably, developing into one of the 200 different cancer types. Cancer is the second leading cause of death in the United States, with approximately 1.8 million new cases occurring this year. Current cancer detection and treatment techniques are costly and not optimal, due to the lack of cancer specificity as well as early detection achieved in some cancer types. This …

Production And Purification Of Aromatase For Co-Crystallization, Bryant Avila

Kansas State University Undergraduate Research Conference

Aromatase (CYP19) is an enzyme that converts androgens into estrogens. It is a drug target to treat hormone-dependent breast cancer, yet current therapeutics often result in patient health deterioration due to unwanted side effects. We want to recombinantly express high yields of stable aromatase to co-crystallize with our new, potent inhibitors. These crystals will be used to produce a 3-D structure to visualize the protein-inhibitor complex. We hope that the structure will help us understand the interactions that are essential for drug potency. We currently produce 1 mg/mL of protein. We hope to increase the stability with mutants A419S, G156A, …

Updates On Epigenetic Alterations To Brca1: Chemosensitivities, Haley Blum

UNO Student Research and Creative Activity Fair

Breast cancer 1, early onset (BRCA1) is a human tumor suppressor gene encoding the BRCA1 protein that maintains genomic integrity. Molecular events may contribute to the loss of BRCA1 function, contributing to site specific tumorigenesis. Loss of BRCA1 function may arise from mutation or epigenetic events. Germline mutations of BRCA1 have been thoroughly implicated in heritable breast and ovarian cancers. More recently, sporadic breast cancer has been shown to be driven by epigenetic alterations to the BRCA1 promoter region, specifically methylation. Breast carcinomas that present with BRCA1 promoter methylation have been associated with triple negative breast cancers, as well …

The Opioid Crisis: Exploring The Effects On First Responders And Healthcare Professionals, Rachel Lubischer, Dawne Frain

UNO Student Research and Creative Activity Fair

In 2017, the National Department of Health and Human Services declared the opioid crisis a public health emergency (The White House, 2018). Although Nebraska ranks among the states with the lowest number of drug overdose deaths, rising opioid use creates safety concerns for first responders and healthcare professionals, and leads to strained resources in many jurisdictions. We hope to increase our audience’s knowledge on the opioid crisis, how it effects first responders and healthcare professionals, and pertinent policies and initiatives in Nebraska. Our audience will leave this presentation better equipped to initiate discussions with friends, family, and community members about …

Synthesis Of A Sulfur Variant For Treatment Of Trypanosomiasis, Carlos Vera-Esquivel

UNO Student Research and Creative Activity Fair

Previous work in our lab has found diphenyl ether benzylamines showed a successful response with a micromolar concentration of our lead compound to treat the deadly Trypanosamiosis rhodesience. Furthermore, mammalian cell lines saw promising resistance towards damages. The goal of this study was to synthesize a diphenyl thio benzylamine variant. This variant was more active toward T. b. rhodesience but showed more toxicity to both rat 10 (IC₅₀ mM) and human cell lines (HFF, HC-₀₄, U-₂ OS, and HEK₂₉₃). The selectivity index (ratio of toxicity to activity in the same concentration units (SI)) …
