Exploring Hypertension Prevalence Through Perceived Health Beliefs, Sarah E. Wagman Dec 2024

Exploring Hypertension Prevalence Through Perceived Health Beliefs, Sarah E. Wagman

Honors Capstones

Hypertension is a form of heart disease that is extremely prevalent, affecting many Americans. This disease manifests from countless risk factors often modifiable from an individual’s lifestyle behavior. Many health initiatives are understood by the public including healthy eating, exercise, and maintaining adequate health, but incidence continues to rise. To better understand this occurrence, a framework called the Health Belief Model is used to answer why individuals make the health decisions that they do in relation to hypertension. Participants in both individual, small group, and large group settings were invited to attend a Hypertension Awareness Event. Participants were asked to …

Bile Duct Ligation-Induced Cirrhosis Does Not Alter The Blood-Brain Barrier Permeability To Sucrose In Rats, Mohammad K. Miah, Ulrich Bickel, Reza Mehvar

Pharmacy Faculty Articles and Research

Contradictory results have been reported about the effects of liver diseases on the blood-brain barrier (BBB) permeability to markers. For instance, both an increase and no change in the BBB permeability to BBB markers sodium fluorescein and Evans blue have been reported in experimental cholestasis induced by bile duct ligation (BDL) in rats. These contradictory effects might be due to inherent limitations of these markers and/or methodological issues. Here, we investigated the time course of the impact of BDL in rats on BBB permeability using a recently developed stable isotope labeled marker [13C]sucrose, which is expected to be …

Computational Logp Calculations And Determination Of Lipophilicity Values Of Fluorinated Morphine Derivatives, Mirabella Romano, Allison Vu, Emily Chen Dec 2024

Computational Logp Calculations And Determination Of Lipophilicity Values Of Fluorinated Morphine Derivatives, Mirabella Romano, Allison Vu, Emily Chen

Student Scholar Symposium Abstracts and Posters

The addictive effect of opioids impacted 60 million people globally in 2023. This opioid crisis necessitates the development of opioid derivatives that maintain analgesic efficacy while minimizing addictive effects from opioid use. The present work focuses on morphine, a commonly prescribed opioid with high affinity to the mu-opioid receptor (MOR). Morphine binds non-selectively within both healthy and inflamed tissue. By modifying morphine’s structure through fluorination to counteract its non-selective binding, the drug’s pharmacological ability to provide effective pain relief comes with a lower risk of addiction. Specifically, the addition of fluorine to differing beta positions of the main binding site …

School of Podiatric Medicine Publications

To compare the incidence of infection, wound closure and time to wound closure in patients treated with cryopreserved (CPUT) and lyopreserved umbilical tissue (LPUT) in complex diabetic surgical wounds. This single-blinded 12-week randomized clinical trial compared cryopreserved and lyopreserved amniotic cord tissue to treat complex diabetic foot wounds. LPUT or CRAT was applied at baseline and again after four weeks. We enrolled subjects with UT2A-D and 3A-D wounds (depth to tendon, muscle, or bone with infection and/or PAD) and excluded subjects with ABI < 0.5 or TBI < 0.3, untreated osteomyelitis, and autoimmune diseases. We used a 3-D camera to evaluate wound area and volume. The mean baseline wound areas were 12.9 ± 10.7 cm2 for CPUT and 11.7 ± 7.0 cm2 for LPUT. The mean baseline wound volume was 7.5 ± 8.1 for CPUT and 9.2 ± 10.2 cm3 for LPUT. There was no difference between CPUT and LPUT in wound closure (36.8% vs 19.0%, P = .21) or infection (10.5% vs 4.8%, P = .60). There was no difference in mean …

Predictors Of Longitudinal Symptom Trajectory In Young Adults With Low Back Pain, Abby Borlovan, Julia Leigh, Jo Armour Smith

Student Scholar Symposium Abstracts and Posters

Predictors of longitudinal symptom trajectory in young adults with low back pain. Severity and frequency of painful episodes change over time in individuals with chronic low back pain (LBP). Recalling previous episodes’ severity/frequency is often considered inaccurate. This study’s purpose was to determine if recall of LBP history or psychological characteristics are predictors of future symptom trajectories in young adults with LBP. The 57 young adult participants had a year or more history of LBP and were not currently in pain. At baseline, LBP history was characterized by recall of pain severity and frequency during symptomatic episodes. Participants completed measures …


Effects Of Simultaneous Smartphone Texting And Auditory Stimulation On Gait, Sebastian Herrera Vargas Dec 2024

Effects Of Simultaneous Smartphone Texting And Auditory Stimulation On Gait, Sebastian Herrera Vargas

Student Scholar Symposium Abstracts and Posters

More often than not, pedestrians around busy college campuses, business parks, and shopping malls are seen walking while using their phones and listening to music or having earphones in. Activities on pedestrians’ phones that captivate them more and require higher cognitive processing demonstrated a higher detriment to their gait kinematics than less cognitively complicated activities (Brennan and Preloff, 2021). This study aims to establish whether or not gait parameters are affected by walking while engaging in cognitively demanding activities such as texting and listening to green noise. Green noise is a deviation from white noise, which amplifies the mid-range frequencies …

Faculty, Staff and Student Publications

The ability to sense and respond to host defenses is essential for pathogen survival. Some mechanisms involve two-component systems (TCSs) that respond to host molecules, such as antimicrobial peptides (AMPs), and activate specific gene regulatory pathways to aid in survival. Alongside TCSs, bacteria coordinate cell division proteins, chaperones, cell wall sortases, and secretory translocons at discrete locations within the cytoplasmic membrane, referred to as functional membrane microdomains (FMMs). In group A Streptococcus (GAS), the FMM or “ExPortal” coordinates protein secretion, cell wall synthesis, and sensing of AMP-mediated cell envelope stress via the LiaFSR three-component system. Previously, we showed that GAS …

Telomere biology disorders (TBDs), caused by pathogenic germ line variants in telomere-related genes, present with multiorgan disease and a predisposition to cancer. Clonal hematopoiesis (CH) as a marker of cancer development and survival in TBDs is poorly understood. Here, we characterized the clonal landscape of a large cohort of 207 patients with TBD with a broad range of age and phenotype. CH occurred predominantly in symptomatic patients and in signature genes typically associated with cancers: PPM1D, POT1, TERT promoter (TERTp), U2AF1S34, and/or TP53. Chromosome 1q gain (Chr1q+) was the commonest karyotypic abnormality. Clinically, multiorgan involvement and CH in TERTp, TP53, …

BACKGROUND: Mesenchymal stem cells (MSCs) derived from gestational tissues offer a promising avenue for prenatal intervention in congenital malformations although their application is hampered by concerns related to cellular plasticity and the need for invasive, high-risk surgical procedures. Here, we present naturally occurring exosomes (EXOs) isolated from amniotic fluid-derived MSCs (AF-MSCs) and their mimetic analogs (MIMs) as viable, reproducible, and stable alternatives. These nanovesicles present a minimally invasive therapeutic option, addressing the limitations of MSC-based treatments while retaining therapeutic efficacy.

METHODS: MIMs were generated from AF-MSCs by combining sequential filtration steps through filter membranes with different porosity and size exclusion …

Chemically induced proximity modalities such as targeted protein degradation (TPD) hold promise for expanding the number of proteins that can be manipulated pharmacologically. However, current TPD strategies are often limited to proteins with preexisting ligands. Molecular glues (e.g. glutarimide ligands for CUL4CRBN), offer the potential to target undruggable proteins. Yet, their rational design is largely unattainable due to the unpredictability of the ‘gain-of-function’ nature of the glue interaction upon chemical modification of ligands. We recently reported a covalent trans-labelling glue mechanism which we named ‘Template-assisted covalent modification’, where an electrophile decorated BRD4 inhibitor was effectively delivered to …

Four main medulloblastoma (MB) molecular subtypes have been identified based on transcriptional, DNA methylation, and genetic profiles. However, it is currently not known whether 3D genome architecture differs between MB subtypes. To address this question, we performed in situ Hi-C to reconstruct the 3D genome architecture of MB subtypes. In total, we generated Hi-C and matching transcriptome data for 28 surgical specimens and Hi-C data for one patient-derived xenograft. The average resolution of the Hi-C maps was 6,833 bp. Using these data, we found that insulation scores of topologically associating domains (TADs) were effective at distinguishing MB molecular subgroups. TAD …

A Comparative Study Of Yoga And Stoicism For Achieving Mental Well-Being, Dr. R K Roshni Raj Lakshmi, Mr. Puyam Robinchandra Singh

Journal of Applied Yoga Studies

Background: The ideal way of life is a question perused upon by many thinkers. Western philosophy as well as Indian philosophy has dwelled on this. A common thread can be seen running through philosophical schools of stoicism and yoga. Evidence can be seen in both schools of philosophy to prove this similarity. The concepts of stoicism like the dual powers leading to creation, concept of eudemonia, restraint of sense organs and control of desire find their equivalent concepts in yoga texts. It can be thus, concluded that stoicism can be seen intertwined in yoga philosophy.
