IMPORTANCE: With increasing medicinal and recreational cannabis legalization, there is a public health need for effective and unbiased evaluations for determining whether a driver is impaired due to Δ9-tetrahydrocannabinol (THC) exposure. Field sobriety tests (FSTs) are a key component of the gold standard law enforcement officer-based evaluations, yet controlled studies are inconclusive regarding their efficacy in detecting whether a person is under the influence of THC.

OBJECTIVE: To examine the classification accuracy of FSTs with respect to cannabis exposure and driving impairment (as determined via a driving simulation).

DESIGN, SETTING, AND PARTICIPANTS: This double-blind, placebo-controlled parallel randomized clinical trial was …

Biomedical Sciences Faculty Publications

Mechanisms linking intestinal bacteria and neurodegenerative diseases such as Alzheimer’s disease (AD) are still unclear. We hypothesized that intestinal dysbiosis might potentiate AD, and manipulating the microbiome to promote intestinal eubiosis and immune homeostasis may improve AD-related brain changes. This study assessed sex differences in the effects of oral probiotic, antibiotics, and synbiotic treatments in the AppNL-G-F mouse model of AD. The fecal microbiome demonstrated significant correlations between bacterial genera in AppNL-G-F mice and Aβ plaque load, gliosis, and memory performance. Female and not male AppNL-G-F mice fed probiotic but not synbiotic exhibited a decrease in Aβ plaques, microgliosis, brain …


Hla-Ii Alleles Influence Physical And Behavioral Responses To A Whey Allergen In A Transgenic Mouse Model Of Cow's Milk Allergy, Danielle L. Germundson, Suba Nookala, Nicholas A. Smith, Yassmine Warda, Kumi Nagamoto-Combs Sep 2023

Hla-Ii Alleles Influence Physical And Behavioral Responses To A Whey Allergen In A Transgenic Mouse Model Of Cow's Milk Allergy, Danielle L. Germundson, Suba Nookala, Nicholas A. Smith, Yassmine Warda, Kumi Nagamoto-Combs

Biomedical Sciences Faculty Publications

The symptoms of food allergies vary significantly between individuals, likely due to genetic determinants. In humans, allergy development is initiated by antigen-presenting cells via class II human leukocyte antigen (HLA-II). The HLA-II gene is highly polymorphic, and its allelic variance is thought to influence the susceptibility of individuals to a particular allergen. However, whether antigen presentation by different HLA-II variants contributes to symptom variation is not clear. We hypothesized that HLA-II allelic variance affects symptom phenotypes, including immediate physical reactions and delayed behavioral changes, in individuals with food hypersensitivity. To test our hypothesis, male and female mice of three transgenic …

Biomedical Sciences Faculty Publications

Mouse models of food allergy have contributed to our understanding of various aspects of the disease, including susceptibilities, symptom spectra, cellular mechanisms, and therapeutic approaches. Previously, we used a mouse model of non-anaphylactic cow’s milk allergy (CMA) and investigated sex- and strain-dependent differences in immunological, neurological, and behavioral sequelae. We showed that male C57BL/6J mice sensitized to a bovine whey protein, β-lactoglobulin (BLG; Bos d 5), exhibited anxiety- and depression-like behavior upon acute allergen challenge. Systemic levels of BLG-specific immunoglobulins, cytokines and chemokines were also elevated in the sensitized mice. Furthermore, neuroinflammation and intestinal dysbiosis were evident as the possible …

Comparison Of Thickness Between Thermoformed And Printed Orthodontic Aligners, Omar Souman Sep 2023

Comparison Of Thickness Between Thermoformed And Printed Orthodontic Aligners, Omar Souman

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: The fabrication of thermoformed orthodontic aligners involves processes that irreversibly alter material properties, resulting in aligners that exhibit high variation in thickness. The non-uniform thickness can lead to unpredictable forces that can adversely affect orthodontic tooth movement. With recent technological advancements enabling the printing of orthodontic aligners, it is of clinical interest to investigate their variation of thickness.

Purpose: This study utilized Micro-Computed Tomography (Micro-CT) and Geomagic Control X metrology software to compare the thickness of thermoformed and direct printed aligners.

Materials and Methods: Intraoral scans of 13 orthodontic patients were used to generate standard tessellation …

Hla-Ii-Dependent Neuroimmune Changes In Group A Streptococcal Necrotizing Fasciitis, Ganesh Ambigapathy, Santhosh Mukundan, Kumi Nagamoto-Combs, Colin Combs, Suba Nookala

Biomedical Sciences Faculty Publications

Streptococcus pyogenes (Group A Streptococcus, GAS) bacteria cause a spectrum of human diseases ranging from self-limiting pharyngitis and mild, uncomplicated skin infections (impetigo, erysipelas, and cellulitis) to highly morbid and rapidly invasive, life-threatening infections such as streptococcal toxic shock syndrome and necrotizing fasciitis (NF). HLA class II allelic polymorphisms are linked with differential outcomes and severity of GAS infections. The dysregulated immune response and peripheral cytokine storm elicited due to invasive GAS infections increase the risk for toxic shock and multiple organ failure in genetically susceptible individuals. We hypothesized that, while the host immune mediators regulate the immune responses against …

Chronic traumatic encephalopathy (CTE) is a progressive neurodegenerative disease that emerges as a result of repetitive mild traumatic brain injury and has been studied within athletes of all sports. Repetitive blows to the brain are associated with many pathological changes and an emergence of tau pathology, all of which can lead to presentation with cognitive dysfunction, behavioral changes, and further motor decline in the later stages. After passing the inclusion criteria, a meta-analysis comprising four articles was computed using Comprehensive Meta-Analysis Version 3. Two hypotheses were examined: (a) the earlier the age of exposure to football, the greater the likelihood …


Apoe Risk Disclosure: A Review Of Positive And Negative Outcome, Stacey Rowcliffe Sep 2023

Apoe Risk Disclosure: A Review Of Positive And Negative Outcome, Stacey Rowcliffe

Dissertations

Two of this century’s most significant healthcare challenges are Alzheimer’s disease and mild cognitive impairment, with 40 million people suffering from the diseases. In fact, a conservative estimate projects that both conditions will double every 20 years until 2050. Alzheimer’s disease involves memory impairment, disorientation, confusion, and various problematic behaviors. Presently, no prevention method or cure has been discovered for Alzheimer’s. Mild cognitive impairment typically includes problems with memory, language, thinking, and judgment beyond those typical of one’s age. Usually, these symptoms do not interfere with daily activities but do not improve and have been linked with a risk of …


Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue Sep 2023

Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue

Dissertations, Theses, and Capstone Projects

People with nonfluent aphasia (PWNA) require feedback from an external agent as well self-feedback to facilitate performance of language production tasks. The extent to which PWNA can use self-feedback alone to improve their task performance is unknown. In addition, it is argued that self-feedback may reinforce or minimize performance errors over time. To test whether either is the case, we introduce an original learning mechanism, recursive functional learning, which uses self-feedback loops to optimize recursively multiple subsystems (cognitive and linguistic subsystems) that PWNA engage during task performance. We used this mechanism to underpin a novel automated procedure we developed, recursive …

Attenuated Typicality Effect In Category-Based Inferences: Implications For Autism Spectrum Disorder, Janani Rajagopalan

Dissertations, Theses, and Capstone Projects

Individuals diagnosed with Autism Spectrum Disorder (ASD) often encounter challenges in assimilating atypical exemplars into their categorical prototypes, a cognitive hurdle that can impact their interpretative and integrative capacities. Addressing this problem, the present research sought to develop a robust methodological approach to reduce the effect of this disparity. We examined the elements embedded within the category's internal structure, with the intention of experimentally attenuating the pronounced typicality effect, which is often exaggerated in ASD.

Across four experiments, the thesis investigated the cognitive and neural underpinnings that shape the access to the typicality gradient intrinsic to a category's structure. The …

Cardiovascular disease (CVD), the number one cause of death in the U.S., disproportionately affects South Asian Americans (SAAs). Physical activity is a modifiable health behavior that can reduce cardiovascular risk. Health behaviors, such as physical activity, occur within specific social and cultural contexts and are influenced by multiple factors at multiple levels of the social ecological model. This dissertation aimed to provide a rich, culturally-informed understanding of the factors at multiple levels – individual, interpersonal, and cultural –associated with physical activity among SAAs at risk for CVD. A sequential exploratory mixed methods approach was employed to examine social and cultural …


Visualizing Dopamine Activity In Deletion Of D2 Receptors In Medium Spiny Neurons, Kunhee Lee Sep 2023

Visualizing Dopamine Activity In Deletion Of D2 Receptors In Medium Spiny Neurons, Kunhee Lee

Dissertations, Theses, and Capstone Projects

Dopamine has been implicated in motivated behaviors and reinforcement learning. In this study, we are looking at the role of dopamine in allocating efforts when obtaining reward. Using Cre recombinase genetic tool, D2 receptors in striatal indirect pathway neurons were selectively deleted, and dopamine signal was recorded in ventral striatum using fiber photometry. Behaviorally, D2 receptor deletion resulted in less effort in a Progressive Ratio (PR) paradigm shown by decreased breakpoint, number of presses, and reward pellets earned. Due to the previous evidence that dopamine positively modulates effort, we hypothesized that there would be less dopamine release in D2 deleted …

Evaluation Of A Novel Lupus Anticoagulant Assay Designed To Reduce False Positive Results Due To Anticoagulation: A Retrospective Study At A Single Health System, Jessica D. Anderson, Tamara Sabih, Yuying Xing, Lili Zhao, Marc D. Smith

Conference Presentation Abstracts

Introduction: Lupus anticoagulants (LA) are antibodies directed against phospholipids/phospholipid-protein complexes involved in coagulation and are associated with thrombotic events and recurrent fetal loss. There is no gold standard test for LA, therefore at least two LA-specific tests are recommended before excluding LA. Potential testing methods involve dilute Russell viper venom time (dRVVT) and hexagonal phase phospholipid assays (HPPA); however, many of these tests are susceptible to interference with anticoagulant therapy which can lead to false positive results. In this study, we compared the performance of our current HPPA, StaClot LA (SCLA), with a novel assay reported to have relatively minimal …

Faculty, Staff and Student Publications

In biomedical science, analyzing treatment effect heterogeneity plays an essential role in assisting personalized medicine. The main goals of analyzing treatment effect heterogeneity include estimating treatment effects in clinically relevant subgroups and predicting whether a patient subpopulation might benefit from a particular treatment. Conventional approaches often evaluate the subgroup treatment effects via parametric modeling and can thus be susceptible to model mis-specifications. In this paper, we take a model-free semiparametric perspective and aim to efficiently evaluate the heterogeneous treatment effects of multiple subgroups simultaneously under the one-step targeted maximum-likelihood estimation (TMLE) framework. When the number of subgroups is large, we …

To date, thousands of highly abundant and conserved single-stranded RNA molecules shaped into ring structures (circRNAs) have been identified. CircRNAs are multifunctional molecules that have been shown to regulate gene expression transcriptionally and post-transcriptionally and exhibit distinct tissue- and development-specific expression patterns associated with a variety of normal and disease conditions, including cancer pathogenesis. Over the past years, due to their intrinsic stability and resistance to ribonucleases, particular attention has been drawn to their use as reliable diagnostic and prognostic biomarkers in cancer diagnosis, treatment, and prevention. However, there are some critical caveats to their utility in the clinic. Their …
