Mixed Methods Approach To Assess ‘Placental Opioid-Enhancing Factor’ Activity Within ‘Alternative’ Health Contexts Of Human Maternal Placentophagy, Jacob C. White

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rats with elevated opioid levels experience an even greater increase in pain threshold after placenta or amniotic fluid consumption via placental opioid-enhancing factor (POEF) in the afterbirth. POEF only enhances opioid hypoalgesia; it cannot produce hypoalgesia alone. Although the POEF molecule remains unidentified and its efficacy in humans is unknown, it could be a safe, novel pain treatment. People who consume placenta as an alternative postpartum health practice are ideal for testing POEF bioactivity. Though rat models show that bioactive POEF is highly sensitive, some forms of the practice in humans may conserve POEF.

This project is the first attempt …

A Low Dose Of Electro-Psychedelic Treatment Increases Neuronal Dendritic Arborization And Filopodic Spine Density, Elaine Aquino Vasquez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Neuropsychiatric disorders remain a formidable challenge to the global healthcare system, necessitating innovative treatments to address their complex pathophysiology. Alternative therapeutic approaches, including electroconvulsive treatment (ECT) and psychedelics, have gained attention for their capacity to relieve a broad range of symptoms. ECT is a long-standing effective therapy for patients, especially treatment-resistant ones. Psychedelics, like psilocybin, can induce profound and sustained therapeutic effects. The limited understanding of their mechanisms of action, compounded by the negative stigma surrounding ECT and psilocybin, prevents them from being used as adjunct agents. ECT and psilocybin promote synaptic plasticity and modulate neural remodeling, yet their comparative …

An Examination Of The Teaching And Learning Of Resonance In General Chemistry I And Organic Chemistry I Using Variation Theory, Sabrina Barakat

UNLV Theses, Dissertations, Professional Papers, and Capstones

Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I, reintroduced in Organic Chemistry I, and then utilized throughout other higher-level chemistry courses. A molecule or ion can be said to exhibit resonance when it can be represented by two or more chemical structures (i.e., Lewis structures) that differ only in their arrangement of electrons. In other words, resonance represents the electronic structure of a molecule or ion when a single Lewis structure does not adequately depict the true distribution of electrons. The molecule or ion is best represented as a combination of all of the …

Perceptions Of A Community-Based Playgroup To Promote Caregiver Knowledge Of Resources And Prevention Of Developmental Delays In A Rural Setting, Chesnee Clingman

UNLV Theses, Dissertations, Professional Papers, and Capstones

For children living in rural communities, the likelihood of having a developmental delay substantially increases compared to children living in urban areas (Weglarz-Ward et al., 2019). This can be due to a lack of access to resources, limited education, and geographical isolation. Despite the rising trend of developmental delays among rural children, there is a noteworthy lack of early intervention resources for both the child and their family. This trend of minimal resources is demonstrated in Lincoln County, Nevada. Using an occupational therapy lens, a community-based playgroup program was developed for residents in Lincoln County. Community-based playgroups involve a structured …
