Tick-borne diseases are becoming increasingly prevalent throughout the United States, particularly in the region of Central Virginia. Ticks carry parasites (Babesia), bacteria, viruses, and toxic sugars (alpha-gal) that can be transmitted during blood meals. Lyme disease, caused by the pathogen Borrelia burgdorferi, is the most common tick-borne disease in the Eastern United States. Symptoms are flu-like with a characteristic bullseye rash (erythema migrans). Recently, the prevalence of Alpha-gal syndrome has risen in Central Virginia, marked by an allergic response to the alpha-gal sugar molecule, which is present in red meat. Dr. Thomas Platts-Mills is credited with discovering Alpha-gal syndrome and …

Hargreaves Test On Formalin Injected Mice: A Neuropathic Pain Model, Caleb Mast

Liberty University Research Week

Neuropathic pain is a chronic condition resulting from nervous system injury or disease, commonly associated with multiple sclerosis, spinal cord injury and diabetes. Current mouse models rely on invasive surgical techniques such as spinal nerve ligation (SNL) or chronic constriction injury (CCI), which require specialized training, increase variability, and reduced accessibility. Previous studies in rats have shown that formalin injections can induce a persistent pain state and spinal molecular changes comparable to those observed in surgical models. This study investigated whether a single subcutaneous injection of 5% formalin is sufficient to produce neuropathic pain behaviors and nervous tissue changes CCI …

Hope: A Vital Sign In Behavioral Health, Isaac Uehling, Alexis Lykins, Jade Gordon, Kelsey Messer

Liberty University Research Week

Hope at its core is the key motivating factor for patient’s pursual of behavioral health interventions, and is a critical upstream factor in the success of behavioral health treatments. The current understanding of hope is centered around goal-making and pathway engagement (Snyder et al., 1991). Although these concepts contribute to hope’s definition, they don’t fully encapsulate the multifaceted nature of hope. Our current study is a continuation of a previous study that expanded the definition of hope through an explorative lens by developing a multi-dimensional instrument – the Powers of Hope Scale. This scale assesses an individual’s level of hope …

Development Of A Teaching-Laboratory Protocol For The Separation Of Adulterant Compounds Caffeine And Quinine Used In Illicit Drugs, Rachel Boktor

Liberty University Research Week

Adulterant compounds are added to illicit drugs to dilute their potency, mimic their effects, and cheapen production. Adulterants caffeine (21%) and quinine (20%) are most frequently combined with fentanyl. Despite their prevalence, there is limited empirical literature on the physical separation of adulterant mixtures. This study aimed to develop a traditional bench-scale separation scheme for isolating legal adulterants from a binary mixture. We hypothesize that differences in water solubility and extraction behavior of caffeine and quinine would enable their separation into distinct fractions. The separation scheme involved selective dissolution, gravity filtration, liquid-liquid extraction, drying, and solvent removal. Following physical separation, …

Exploration Of Preservative-Surfactant Aggregation Effects On Biologic Drug Formulations, Joseph Turmelle

Liberty University Research Week

A key challenge in the development of injectable drug formulations is the need for multi-dose administration, which increases the risk of bacterial contamination. To reduce this risk, preservatives such as phenol (PhOH) and benzyl alcohol (BzOH) are commonly added to formulations. However, preservatives can aggregate with other critical excipients, particularly surfactants such as polysorbate 20 (PS20). This aggregation leads to physical instability, often observed as turbidity or precipitation. Previous work has shown that preservatives induce the formation of large, unstable aggregates with surfactants at pharmaceutically relevant concentrations. The purpose of this study is to characterize and understand this phenomenon of …
