Characterizing Range Anxiety In Electric Vehicle Users, Maiia Tolia-Shah, Brenda Gutierrez, Sook Mun (Alice) Wong, Uri Maoz

Student Scholar Symposium Abstracts and Posters

Range Anxiety is the fear of running out of fuel for your car before arriving at a refueling point or final destination. While usually absent or low in gas-powered vehicles, this anxiety is a salient consideration when buying electric vehicles (EVs). This and the fact that there are fewer charging stations available compared to gas stations have been offered as hypotheses for why EV sales are low. Previous research has found that those with more experience driving EVs, felt less range anxiety as they can when and where to charge their vehicle in their daily lives. EVs are more environmentally …

Health And Quality Of Life Of Children Undergoing Elective Surgery, Vivian Luong

Student Scholar Symposium Abstracts and Posters

Multiple studies have found that poorer health is associated with significantly lower quality of life when comparing children and adults with health conditions such as cancer, diabetes, asthma, and ADHD to their normal healthy counterparts. The relationship between health and quality of life, however, has yet to be examined in children who have undergone elective surgery. More than 5 million children in the U.S. undergo surgery each year. These children are often undergoing surgery for a number of health issues that may impede quality of life. Consequently, this study analyzes the effects of health on the quality of life of …

Effect Of Tyrosine On The Productivity Of Pc12 Cells By Measuring Extracellular Atp Release, Sabrina Burkholder, Mary Rapmund, David Fogel, Jon Flees

Student Scholar Symposium Abstracts and Posters

Given the challenge to “reverse-engineer the brain”, our group tried to address the problems of a lack of long term focus and attention span. Tyrosine was determined to aid in mental focus and brain productivity as it is a precursor to the neurotransmitter Dopamine. Given that Tyrosine is naturally occurring in the body, it is preferable to add to the body, whereas a substance like Adderall has negative effects, including increased heart rate that, over time, can cause cardiovascular damage. Drawing connections between in increase ATP and an increased ability to focus and perform under stress, extracellular ATP secretion of …

Measuring Neural Time Series Data In A Sensory Deprivation Tank, Jackson Gregory, Tian Lan, Uri Maoz, Amir Raz

Student Scholar Symposium Abstracts and Posters

We are interested in studying the neurological and physiological effects of the float pod, also known as REST therapy, or sensory deprivation tank. Float pods rely on the concept of depriving most senses (from sound and light to temperature and proprioception) in a pool filled with buoyant salt water at body temperature. While float pods are most commonly used in spa environments, we intend to look at the potential benefits of floating under the empirical lens. In this study, we aim to measure neural activity using electroencephalography (EEG). We intend to look at the different levels of relaxation and the …

Reporting Charcoal Rot In Chia And Developing A Susceptibility Assay, Reis M. Misaka, Hagop S. Atamian Dr., Julien Besnard Dr.

Student Scholar Symposium Abstracts and Posters

Chia (Salvia Hispanica) cross breeds were planted in the summer of 2018 with the intent of selective breeding for agricultural benefit. Preexisting pathogens in the soil caused 40-50% fatality of adult plants. This was surprising due to the precursory knowledge that chia has antibiotic and antifungal oils (Elshafie et. al. 2018); chia was only recently documented to be susceptible to Fusarium wilt (Fusarium oxysporum). The primary pathogen responsible was identified as Macrophomina phaseolina (aka charcoal rot); a widespread soilborne pathogen which has multiple commercial hosts (Su et. al. 2001).

Exploring The Relationship Of Digital Information Sources And Medication Adherence, Cody Arbuckle, Daniel Tomaszewski, Lawrence Brown, Jon C. Schommer, Donald Morisky, Chelsea Parlett-Pelleriti, Erik J. Linstead

Pharmacy Faculty Articles and Research

We present a retrospective analysis of data collected in the United States from the 2015 National Consumer Survey on the Medication Experience and Pharmacists’ Role in order to model the relationship between health information sources and medication adherence and perception. Our results indicate that while the digital age has presented prescription users with many non-traditional alternatives for health information, the use of digital content has a significant negative correlation with pharmaceutical adherence and attitudes toward medication. These findings along with previous research suggest that in order to fully realize the potential benefits of the digital age in regards to patient …

Does It Matter Whether You Or Your Brain Did It? An Empirical Investigation Of The Influence Of The Double Subject Fallacy On Moral Responsibility Judgments, Uri Maoz, Kellienne R. Sita, Jeroen J. A. Van Boxtel, Liad Mudrik

Psychology Faculty Articles and Research

Despite progress in cognitive neuroscience, we are still far from understanding the relations between the brain and the conscious self. We previously suggested that some neuroscientific texts that attempt to clarify these relations may in fact make them more difficult to understand. Such texts—ranging from popular science to high-impact scientific publications—position the brain and the conscious self as two independent, interacting subjects, capable of possessing opposite psychological states. We termed such writing ‘Double Subject Fallacy’ (DSF). We further suggested that such DSF language, besides being conceptually confusing and reflecting dualistic intuitions, might affect people’s conceptions of moral responsibility, lessening the …

Sensory Primary Cilium Is A Responsive Camp Microdomain In Renal Epithelia, Rinzhin T. Sherpa, Ashraf M. Mohieldin, Rajasekharreddy Pala, Dagmar Wachten, Rennolds S. Ostrom, Surya M. Nauli

Pharmacy Faculty Articles and Research

Primary cilia are hair-like cellular extensions that sense microenvironmental signals surrounding cells. The role of adenylyl cyclases in ciliary function has been of interest because the product of adenylyl cyclase activity, cAMP, is relevant to cilia-related diseases. In the present study, we show that vasopressin receptor type-2 (V2R) is localized to cilia in kidney epithelial cells. Pharmacologic inhibition of V2R with tolvaptan increases ciliary length and mechanosensory function. Genetic knockdown of V2R, however, does not have any effect on ciliary length, although the effect of tolvaptan on ciliary length is dampened. Our study reveals that tolvaptan may have a cilia-specific …

Pharmacy Faculty Articles and Research

A number of amphiphilic cyclic peptides—[FR]4, [WR]5, and [WK]5—containing hydrophobic and positively-charged amino acids were synthesized by Fmoc/tBu solid-phase peptide methods and evaluated for their efficiency in intracellular delivery of siRNA to triple-negative breast cancer cell lines, MDA-MB-231 and MDA-MB-468, in the presence and absence of 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE). Among the peptides, [WR]5, which contains alternate tryptophan (W) and arginine (R) residues, was found to be the most efficient in the delivery of siRNA by improving the delivery by more than 3-fold when compared to other synthesized cyclic peptides that were not efficient. The data also showed that co-formulation of [WR]5 …

Differences In Tsimane Children’S Growth Outcomes And Associated Determinants As Estimated By Who Standards Vs. Within-Population References, Melanie Martin, Aaron Blackwell, Hillard Kaplan, Michael Gurven

Economics Faculty Articles and Research

Anthropometric measures are commonly converted to age stratified z-scores to examine variation in growth outcomes in mixed-age and sex samples. For many study populations, z-scores will differ if calculated from World Health Organization (WHO) growth standards or within-population references. The specific growth reference used may influence statistical estimates of growth outcomes and their determinants, with implications for biological inference. We examined factors associated with growth outcomes in a sample of 152 Tsimane children aged 0–36 months. The Tsimane are a subsistence-scale population in the Bolivian Amazon with high rates of infectious disease and growth faltering. To examine the influence of …

Delay Discount Rate Moderates A Physical Activity Intervention Testing Immediate Rewards, Christine B. Phillips, Jane C. Hurley, Siddhartha S. Angadi, Michael Todd, Vincent Berardi, Melbourne Hovell, Marc A. Adams

Psychology Faculty Articles and Research

Financial incentives can increase physical activity (PA), but differences in the immediacy of reward delivery and individual differences in delay discount rates (i.e., higher discount values associated with less tolerance for delayed rewards) may explain differential responding. The current study tested whether delay discount rate moderated the relative effectiveness of immediate financial rewards on increasing daily PA. Inactive, overweight adults (ages 18–60, N = 96) were randomized to receive either smaller, immediate goal-contingent rewards or larger, delayed rewards for participation. Delay discount rates were derived for those who completed the Monetary Choice Questionnaire (N = 85). Linear mixed models tested …

The purpose of this study was to evaluate the effect of fluorometholone, a glucocorticoid receptor agonist used in the management of dry eye, on the gene expression of conjunctival and corneal epithelial cell mucins.

Methods

Stratified cultures of human conjunctival and corneal epithelial cells were exposed to 25, 50 and 100 nM of fluorometholone alone or in presence of mifepristone, a glucocorticoid receptor antagonist. The mRNA was isolated from the cells and reverse transcribed to cDNA. The cDNA was used for …

Cannabinoid Hyperemesis Syndrome: An Unrecognized Cause Of Nausea And Vomiting, Tiffany Smith, Anne Walsh, Christopher Forest

Physician Assistant Studies Faculty Articles and Research

Cannabis has long been used for medical and recreational purposes because of its antiemetic, analgesic, and mood effects. Ironically, chronic use of cannabis can result in paradoxical effects, including a condition known as cannabinoid hyperemesis syndrome. Patients with this syndrome often are seen in the ED with cyclic vomiting, nausea, and epigastric pain. Although the definitive treatment of cannabinoid hyperemesis syndrome is discontinuing the causative agent, medical management that includes rehydration is important to prevent complications. Common antiemetic medications are ineffective, but some studies have shown haloperidol and lorazepam to be effective in treating acute symptoms.

Ecological Determinants Of Respiratory Health: Examining Associations Between Asthma Emergency Department Visits, Diesel Particulate Matter, And Public Parks And Open Space In Los Angeles, California, Jason A. Douglas, Reginald S. Archer, Serena E. Alexander

Health Sciences and Kinesiology Faculty Articles

Los Angeles County (LAC) low-income communities of color experience uneven asthma rates, evidenced by asthma emergency department visits (AEDV). This has partly been attributed to inequitable exposure to diesel particulate matter (DPM). Promisingly, public parks and open space (PPOS) contribute to DPM mitigation. However, low-income communities of color with limited access to PPOS may be deprived of associated public health benefits. Therefore, this novel study investigates the AEDV, DPM, PPOS nexus to address this public health dilemma and inform public policy in at-risk communities. Optimized Hotspot Analysis was used to examine geographic clustering of AEDVs, DPM, and PPOS at the …

Oxytocin Receptor Gene (Oxtr) And Father Support Interact To Predict Depressive Symptoms Postpartum, Parambir Bhatti, Taylor Delaney, Michael Poulin, Jennifer Hahn-Holbrook

Psychology Faculty Articles and Research

Postpartum depression (PPD) is a debilitating mental illness affecting approximately 13% of mothers after birth. Both genetic and psychosocial factors contribute to PPD risk, but very little is known about how these factors interact. We tested whether the rs53576 polymorphism in the oxytocin receptor (OXTR) gene accounts for variation in the impact of low social support as a risk factor for depression among mothers during the perinatal period. New mothers (N = 220) provided saliva or blood DNA samples and completed surveys assessing PPD symptoms and perceived social support. In a significant interaction, social support from the …

2018-2019 Acip Immunization Updates: Highlights For Pharmacists, Laressa Bethishou, Luma Munjy, Jeff Goad

Pharmacy Faculty Articles and Research

"Vaccinations have significantly reduced the burden of infectious diseases, preventing almost 6 million deaths worldwide.^1,2 In the United States, vaccines have led to a decrease in incidence of vaccine-preventable illness, mortality, and disease sequelae.³ Despite the proven benefit of vaccines, misinformation and failure to vaccinate has led to outbreaks of vaccine-preventable diseases. As of December 29, 2018, 372 cases of measles (from 17 outbreaks) and 2251 cases of mumps were reported in the United States in 2018.^4,5 These outbreaks support the need for continued education of patients and active immunization by pharmacists."

The Role Of Thyroglobulin In Thyroid Hormonogenesis, Cintia E. Citterio, Héctor M. Targovnik, Peter Arvan

Pharmacy Faculty Articles and Research

In humans, the thyroid hormones T₃ and T₄ are synthesized in the thyroid gland in a process that crucially involves the iodoglycoprotein thyroglobulin. The overall structure of thyroglobulin is conserved in all vertebrates. Upon thyroglobulin delivery from thyrocytes to the follicular lumen of the thyroid gland via the secretory pathway, multiple tyrosine residues can become iodinated to form mono-iodotyrosine (MIT) and/or di-iodotyrosine (DIT); however, selective tyrosine residues lead to preferential formation of T₄ and T₃ at distinct sites. T₄ formation involves oxidative coupling between two DIT side chains, and de novo T₃ formation involves …
