The Detection Of Clozapine In Oral Fluid Via A Kinetic Interaction Of Microparticles In Solution (Kims) Assay, Elizabeth Gunning

Student Theses

In recent years, the use of antipsychotic medications has rapidly increased. Most of these medications have a high risk potential. Due to this risk potential, patients who are prescribed these medications have to be monitored. Therapeutic drug monitoring (TDM) has become extremely important in the clinical environment. Physicians rely on TDM to make sure patients are adhering to their prescription and to make decisions about whether the medication is working. Clozapine is a very popular antipsychotic used in the treatment of schizophrenia. The current method for TDM for clozapine is a blood test. This causes challenges for physicians, who need …

Imaging Of Transmetallation And Chelation Phenomena Involving Radiological Contrast Agents In Mineral-Rich Fruits, Subhendra Sarkar, Zoya Vinokur, Bleidis Buitrago, Lin Mousa, Hayley Sanchez, Analia Basilicata, Jodi-Ann Douglas, Seanetta Reddock

Publications and Research

Exogenous heavy metals or non-metallic waste products, for example lanthanide or iodinated contrast media for radiological procedures, may interfere with the biochemical pools in patients and in common food sources, creating an excess buildup of exogenous compounds which may reach toxic levels. Although the mechanisms are unknown, our experiments were designed to test if this toxicity can be attributed to “transmetallation” or “chelation” reactions freeing up lanthanides or chelated transition metals in acidic fruits used as phantoms representing the biologically active and mineral-rich carbohydrate matrix. The rapid breakdown of stable contrast agents have been reported at a lower pH. The …

Counting Every Drop: Preventing Maternal Mortality With Quantifying Blood Loss Through Triton Scale, Summer Le

Master's Projects and Capstones

Postpartum (PP) hemorrhage is one of the leading causes of maternal mortality (AWHONN, 2021). In each of the past three years, the percentage of PP hemorrhage has increased at Hospital X. The PP unit at Hospital X performs around 4,500 total deliveries each year. While the standard of care for PP blood loss is to specifically measure blood in milliliters as Quantifying Blood Loss (QBL) for Labor and Delivery (L&D), it is not yet the standard of care in the 24 hours postpartum after delivery (ACOG, 2019). This quality improvement project involved educating nurses about measuring blood loss – specifically …

Use Of Pocus And Omt For Anterior Shoulder Reduction, David Ho, James Espinosa, Alan Lucerna, Neeharika Bhatnagar

Rowan-Virtua Research Day

Shoulder dislocations are very a common presentation in the emergency department. This represents about 50% of all joint dislocations presenting to the ER. Over 95% of the dislocations are anterior. Approximately 70% of shoulder dislocations occur in men and in both genders, the prevalence of shoulder dislocations occurs in a bimodal distribution in age in those younger than 20 and over 60 years old. Shoulder dislocation can occur anteriorly, posteriorly, and inferiorly. In an anterior dislocation, excessive force from external rotation and abduction causes a tear in the anterior ligamentous capsule3, causing the humeral head to dislocate from the glenoid …

Aerobic Exercise As A Pioneer Treatment For Post-Concussion Patients, Neha Bhandari

D.U.Quark

Concussions are highly prevalent injuries in both youth and adult sports and can severely impact daily functions by impairing mental and physical health. Existing treatments, such as resting, have been found to be ineffective in promoting a faster recovery. They often lead to a decline in mental health, which can exacerbate ongoing symptoms. However, aerobic exercise is an emerging field that has the potential to make concussion recovery more effective. This literature review will explore the effectiveness of aerobic exercise on faster recovery rates, return to play, and its impact at the cellular level for concussion patients. In addition, it …

Constructing Neural Network Models From Brain Data Reveals Representational Transformations Linked To Adaptive Behavior, Takuya Ito, Guangyu Robert Yang, Patryk Laurent, Douglas H. Schultz, Michael W. Cole

Center for Brain, Biology, and Behavior: Faculty Publications

The human ability to adaptively implement a wide variety of tasks is thought to emerge from the dynamic transformation of cognitive information. We hypothesized that these transformations are implemented via conjunctive activations in “conjunction hubs”—brain regions that selectively integrate sensory, cognitive, and motor activations. We used recent advances in using functional connectivity to map the flow of activity between brain regions to construct a task-performing neural network model from fMRI data during a cognitive control task. We verified the importance of conjunction hubs in cognitive computations by simulating neural activity flow over this empirically-estimated functional connectivity model. These empiricallyspecified simulations …

Affective Flexibility As A Developmental Building Block Of Cognitive Reappraisal: An Fmri Study, Jordan E. Pierce, Eisha Haque, Maital Neta

Center for Brain, Biology, and Behavior: Faculty Publications

Cognitive reappraisal is a form of emotion regulation that involves reinterpreting the meaning of a stimulus, often to downregulate one’s negative affect. Reappraisal typically recruits distributed regions of prefrontal and parietal cortex to generate new appraisals and downregulate the emotional response in the amygdala. In the current study, we compared reappraisal ability in an fMRI task with affective flexibility in a sample of children and adolescents (ages 6–17, N = 76). Affective flexibility was defined as variability in valence interpretations of ambiguous (surprised) facial expressions from a second behavioral task. Results demonstrated that age and affective flexibility predicted reappraisal ability, …

Robust Testing Of Paired Outcomes Incorporating Covariate Effects In Clustered Data With Informative Cluster Size, Sandipan Dutta

Mathematics & Statistics Faculty Publications

Paired outcomes are common in correlated clustered data where the main aim is to compare the distributions of the outcomes in a pair. In such clustered paired data, informative cluster sizes can occur when the number of pairs in a cluster (i.e., a cluster size) is correlated to the paired outcomes or the paired differences. There have been some attempts to develop robust rank-based tests for comparing paired outcomes in such complex clustered data. Most of these existing rank tests developed for paired outcomes in clustered data compare the marginal distributions in a pair and ignore any covariate effect on …

Altitude Illness, Kali Hepner

Capstone Showcase

With an increasing number of individuals traveling to high altitudes, it is important to address the risk these individuals face of developing altitude related illnesses. An example of high altitude related illness might be the elevation transition of travelers flying into Denver, Colorado (1,673 m) with the intention to then drive up to Rocky Mountain National Park’s Alpine Visitor Center (3,595 m) in the same day. This poses increased risk of unacclimatized visitors experiencing altitude illness in remote areas of the national park. This poster summarizes the diagnosis, prevention, and treatment of altitude illnesses so that clinicians and travelers may …

A Novel Computational Network Methodology For Discovery Of Biomarkers And Therapeutic Targets, Qing Ye

Graduate Theses, Dissertations, and Problem Reports (ETD)

Lung cancer has the second highest cancer incidence rate and the top cancer-related mortality worldwide. An estimate from the American Cancer Society shows that, in 2022, there will be about 236,740 lung cancer cases (117,910 men and 118,830 women) in the US. To date, there are no prognostic/predictive biomarkers to select chemotherapy, immunotherapy, and radiotherapy in individual non-small cell lung cancer (NSCLC) patients. There is an unmet clinical need to identify patients with early-stage NSCLC who are likely to develop recurrence and to predict their therapeutic responses. This dissertation developed a novel computational methodology for modeling molecular gene association networks …

Pulsed Chronopotentiometry With Polymer-Based Potassium-Selective Electrodes, Roland A. Long, Kebede L. Gemene Dr.

Posters-at-the-Capitol

This research aimed to develop ion-selective electrodes selective to potassium for use in measuring potassium concentration in blood. Potassium is an important electrolyte within the body, orchestrating nerve excitation, muscular function, and heart rate. Excessive or insufficient potassium levels can cause breakdowns in these systems difficult to differentiate from other potential causes. Isolating potassium concentration as the sole cause necessitates selective measurement. Pulsed Chronopotentiometry with polymer-based membrane electrodes offered a versatile route of interrogation: membrane composition and magnitude of applied current can be altered to assess selectivity in a fast and controlled manner. All potential measurements recorded corresponded to known …
