Effects Of Cocaine And/Or Heroin Use On Resting Cardiovascular Function, Shabber Syed Bs, Lina A. Shkokani Bs, Leslie H. Lundahl Phd, Renato S. Roxas Md, Philip D. Levy Md, Mark K. Greenwald Phd

Medical Student Research Symposium

Background: Regular cocaine and/or heroin use is associated with major health risks, especially cardiovascular disease (CVD), but confounded by other factors.

Objectives: We examined effects of chronic (years of regular use) and recent (past-month) use of cocaine and heroin, controlling for other factors, on resting cardiovascular function.

Methods: In a sample of cocaine and/or heroin users (N=292), we obtained data on demographics, body mass index (BMI), history of substance use, and electrocardiogram, heart rate (HR) and blood pressure (BP). Following bivariate correlations, three-block (1: demographics, BMI; 2: tobacco, alcohol, marijuana; 3: cocaine, heroin) regression analyses were …

Measuring Mitochondrial Respiration In Vivo: From Mouse To Human, Arthur Orchanian, Brennan Schilling, Bruce Berkowitz Phd

Medical Student Research Symposium

Introduction: The mitochondrial energy ecosystem can be non-invasively interrogated in photoreceptors by combing a clinical tool, optical coherence tomography (OCT), with a mitochondrial protonophore (2,4 dinitrophenol, DNP). It remains unclear if only supra-clinical doses of DNP will be useful for mouse studies or if lower but clinically relevant doses of DNP would facilitate translation from mice to humans.

Methods: The experiment was a paired longitudinal design that took place over 2 days. On day 1, C57BL/6J mice were overnight dark adapted, then light-adapted for 5 h before OCT examination before regaining consciousness; a similar procedure was followed on day 2 …

Inhibition Of The Heg1-Krit1 Interaction Increases Klf4 And Klf2 Expression In Endothelial Cells, Miguel Lopez-Ramirez, Wenqing Li, Mark Haynes, Preston Hale, Sara Mccurdy, Karol Francisco, Killian Oukoloff, Matthew H. Bautista, Chelsea Choi, Hao Sun, Brendan Gongol, John Shyy, Carlo Ballatore, Larry Sklar, Alexandre Gingras

Medical Student Research Symposium

The Kruppel-like Factors 2 and 4 (KLF2/4) are transcription factors and master regulators of endothelial cells (ECs) phenotype and homeostasis. KLF2/4 are important blood-flow-responsive genes within ECs that differentially regulate the expression of factors that confer anti-inflammatory, antithrombotic, and antiproliferative effects in ECs. We found that genetic inactivation of endothelial Krit1 (Krev interaction trapped protein 1) or Heg1 (Heart of glass) led to upregulation of KLF2/4 expression levels. We also observed that vasoprotective proteins, endothelial nitric oxide synthase (eNOS) and thrombomodulin (TM), are upregulated by the increase of KLF2/4 as a result of loss of endothelial KRIT1. Here, we developed …

Coastal Watershed Monitoring And Management: Geomorphology, Geochemistry, And Hydrologic Modeling Of Los Peñasquitos Creek, Ca, Ravleen Khalsa-Basra

Theses

Rivers in semi-arid climates are directly influenced by local geographic and hydrologic conditions and impacted by modifications to hydrology via urbanization. Changes can influence erosion, morphology, habitat sustainability, and watershed health. In highly urbanized southern California coastal regions, these rare open spaces provide vital ecosystem services. Los Peñasquitos Creek in San Diego County is one such watershed. Using stream surveying and laboratory methods we quantified channel characteristics, grain size distribution, total metal concentration [M], organic carbon (%OC), and phosphate to longitudinally characterize the creek for improved management. Results identified three distinct reaches in the watershed (upper, middle, lower). Downstream, depth …

Otolith Microchemistry Reveals Low Habitat Connectivity Of California Killifish (Fundulus Parvipinnis) Across A Range Of Spatial Scales, Lisa Robison

Theses

As wetlands face continued fragmentation worldwide, an understanding of habitat connectivity and how fishes that rely on these environments is imperative to conduct effective marine management. Site fidelity and habitat connectivity are vital measures of the interdependence of fish populations living in neighboring marshes (or in regions of a single marsh).

Here, we examine the habitat connectivity, site fidelity, and movement of California killifish (Fundulus parvipinnis) within and among three estuaries in Southern California through otolith microelemental analysis. Assessing the site fidelity of estuarine fishes is important to determine the level of connectivity between spatially distinct populations within …

“Due Regard” For Commercial Space Must Start With Historic Preservation, Michelle Hanlon

Global Business Law Review

Today we rely on the concept of "due regard" to protect our assets – and heritage – in space. Ensconced in Article IX of the Outer Space Treaty "due regard" has no legal definition. Nor has its breadth or scope been rigorously tested in court or in any public diplomatic dispute. And so, we blithely promise each other to conduct all activities in space "with due regard to the corresponding interests of others." Meaning we pursue our activities with the fervent hope that no one will interfere, whether accidentally or intentionally. This is an untenable state of affairs. It is …

In-Group Versus Out-Group Preferences In Intergroup Conflict: An Experiment, Subhashish M. Chowdhury, Anwesha Mukherjee, Roman M. Sheremeta

ESI Working Papers

Individuals participating in a group conflict have different preferences, e.g., maximizing their own payoff, maximizing the group’s payoff, or defeating the rivals. When such preferences are present simultaneously, it is difficult to distinctly identify the impact of those preferences on conflict. In order to separate in-group and out-group preferences, we conduct an experiment in which human in-group or out-group players are removed while keeping the game strategically similar. Our design allows us to study (i) how effort in a group conflict vary due to in-group and out-group preferences, and (ii) how the impact of these preferences vary when the two …

Using Aerial Photogrammetry And Sexually Dimorphic Measurements To Investigate Seasonal Differences In School Composition Of Delphinus Spp. Off Southern California, Samantha Gm Leander

Theses

Insights into school composition can provide a means to understand basic biology and ecology, including reproductive patterns. They can also be applied to conservation assessments, allowing for better understanding of the potentially differential vulnerability of demographic groups to natural or anthropogenic disturbances that may influence their populations. However, the two subspecies of common dolphins in the waters off California (Delphinus delphis delphis and D. d. bairdii) form large, energetic groups that make characterization of school composition difficult. Remotely controlled drones now offer the opportunity for the study of school composition in Delphinus spp., allowing for precise morphometric measurements …

Developing A Method To Track Marine Snow Aggregation Through Individual Collisions Using Stereoscopic Imaging, Riley Henning

Theses

The aggregation of individual phytoplankton into marine snow allows particles to sink more quickly, thus resulting in the transport of particulate organic carbon from surface waters to the deep ocean. Aggregate formation has previously been measured in experiments indirectly by quantifying how particle size or particle concentration changes over time. Here, I present my thesis in which I applied high-resolution imaging to quantify aggregate formation using two different methodologies.

We conducted experiments to investigate aggregate formation using stereoscopic imaging, tracking individual particles directly in a 3D volume. Phytoplankton cultures were rolled in cylindrical tanks and imaged by two cameras illuminated …

Department of Nutrition and Health Sciences: Faculty Publications

Honey has been used as a nutrient, an ointment, and a medicine worldwide for many centuries. Modern research has demonstrated that honey has many medicinal properties, reflected in its anti-microbial, anti-oxidant, and anti-inflammatory bioactivities. Honey is composed of sugars, water and a myriad of minor components, including minerals, vitamins, proteins and polyphenols. Here, we report a new bioactive component‒vesicle-like nanoparticles‒in honey (H-VLNs). These HVLNs are membrane-bound nano-scale particles that contain lipids, proteins and small-sized RNAs. The presence of plant-originated plasma transmembrane proteins and plasma membrane-associated proteins suggests the potential vesicle-like nature of these particles. H-VLNs impede the formation and activation …

Credit Risk Modelling For Indian Debt Securities Using Machine Learning, Charumathi Balakrishnan, Mangaiyarkarasi Thiagarajan

Bulletin of Monetary Economics and Banking

We develop a new credit risk model for Indian debt securities rated by major credit rating agencies in India using the ordinal logistic regression (OLR). The robustness of the model is tested by comparing it with classical models available for ratings prediction. We improved the model’s accuracy by using machine learning techniques, such as the artificial neural networks (ANN), support vector machines (SVM) and random forest (RF). We found that the accuracy of our model has improved from 68% using OLR to 82% when using ANN and above 90% when using SVM and RF.

The Role Of Technology (Social Media) In Increasing The Awareness Of Healthy Life Styles And Strengthening Social Interactions: An Effort To Handle Covid-19 In The Micro Environment, Eko Wijayanto

International Review of Humanities Studies

The COVID-19 pandemic has changed the interaction patterns and culture of society. The pretext of limiting interactions as the key to handle COVID-19 certainly has various challenges in its implementation in society. Regulators have promulgated various global and national policies (in macro level). It is necessary to ascertain whether the policy can be conveyed and implemented correctly at the micro-level in the community, which has various social and cultural characters. Neighborhood Association (known as Rukun Warga in Indonesia), as the smallest community in society, is undoubtedly the spearhead in ensuring all global and national policies can be carried out correctly. …

Javanese traditional house are built to reflect the microcosm and microcosm of the Javanese philosophy of living. For the Javanese, duality and balance are two important concepts, which is reflected spatially through the how their houses are organized: inside and outside, left and right, rest area and activity area, as well as masculine and feminine spaces. This research discusses the meaning of gendered space in the house nDalem Pangeranam Mertadireja III. Gendered space is the main focus of discussion because gendered activities both shape and are shaped by gendered spaces. Ndalem Pangeranan Mertadireja III is a traditional Javanese house built …

Taking An Environmental Ethics Perspective To Understand What We Should Expect From Eia In Terms Of Biodiversity Protection, Alan Bond, Jenny Pope, Angus Morrison-Saunders, Francois Retief

Research outputs 2014 to 2021

As a globally mandated decision-support tool, Environmental Impact Assessment (EIA) has the potential to contribute to the protection of biodiversity, which is increasingly under threat because of human activities. Concern over its ability to do this, however, has led to the addition of trade-off rules, Ecosystem Services Assessment (ESA), and biodiversity offsets. But given that EIA is set in a political decision-making context, what is reasonable to expect of EIA? In this paper we seek to explore what level of biodiversity protection we can expect EIA to support (and therefore whether these additions are worthwhile). Our point of departure is …

The Mechanism Of Β-N-Methylamino-L-Alanine Inhibition Of Trna Aminoacylation And Its Impact On Misincorporation, Nien-Ching Han, Tammy J. Bullwinkle, Kaeli F. Loeb, Kym F. Faull, Kyle Mohler, Jesse Rinehart, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

β-N-methylamino-l-alanine (BMAA) is a nonproteinogenic amino acid that has been associated with neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD). BMAA has been found in human protein extracts; however, the mechanism by which it enters the proteome is still unclear. It has been suggested that BMAA is misincorporated at serine codons during protein synthesis, but direct evidence of its cotranslational incorporation is currently lacking. Here, using LC-MS–purified BMAA and several biochemical assays, we sought to determine whether any aminoacyl-tRNA synthetase (aaRS) utilizes BMAA as a substrate for aminoacylation. Despite BMAA's previously predicted misincorporation at serine …

Deep Learning For Multi-Tissue Cancer Classification Of Gene Expressions, Tarek Khorshed

Theses and Dissertations

We contribute in saving the lives of cancer patients through early detection and diagnosis, since one of the major challenges in cancer treatment is that patients are diagnosed at very late stages when appropriate medical interventions become less effective and full curative treatment is no longer achievable. Cancer classification using gene expressions is extremely challenging given the complexity and high dimensionality of the data. Current classification methods typically rely on samples collected from a single tissue type and perform a prerequisite of gene feature selection to avoid processing the full set of genes. These methods fall short in taking advantage …
