Exploring The Role Of Reward Functioning In The Overlap Of Post-Traumatic Stress And Cocaine Use Disorder, Kate Hull, Hanaan Bing-Canar, Krista Miloslavich, Christopher Holden, Aneet Ahluwalia, Joy M Schmitz

Faculty, Staff and Student Publications

Background: Posttraumatic stress disorder (PTSD) symptoms are common in people with cocaine use disorder (CUD), and even sub-threshold PSTD symptoms result in worse treatment outcomes. Difficulties with reward functioning may drive this comorbidity. Impairments in reward functioning are prominent in both PTSD and CUD and contribute to development of substance use problems after trauma. There are three distinct reward processes that may be involved in the PTSD/CUD overlap: consummatory reward (ability to experience pleasure), motivational reward (willingness to exert effort for rewards), and reward learning (adapting behavior based on reward history). Here we test whether impairments in these reward functions …

Administration Of Anti-Gfap Antibodies Increases Cgrp Expression And Increases Pain Hypersensitivity In Spinal Cord Injured Animals

Faculty, Staff and Student Publications

Background: Spinal cord injury (SCI) results in a multitude of cellular and pathological changes including neuronal loss, axonal damage, gliosis, and loss of motor and sensory function. In 40%-70% of patients, SCI can also trigger the development of neuropathic pain. Our previous study demonstrated that SCI patients who developed autoantibodies to glial fibrillary acidic protein (GFAP) were at increased risk for the subsequent development of neuropathic pain. However, whether GFAP autoantibodies (GFAPab) contribute to the development of neuropathic pain after SCI had yet to be examined.

Objective: Using a mid-thoracic contusion model of SCI in male Sprague-Dawley rats, we examined …

Faculty, Staff and Student Publications

Background and purpose: Intravenous administration of indocyanine green (ICG) has been approved in brain surgeries for decades, yet concerns about neurotoxicity prevent its direct administration into the cerebrospinal fluid (CSF). Armed with prior animal studies demonstrating the feasibility of using ICG microdosing into the CSF, we sought to evaluate its nonclinical safety profile and obtain surrogate measures in adults prior to its use in human neonates.

Methods: Evaluation of ICG toxicity was conducted in mixed primary CNS cell cultures and in an extended safety study of juvenile rat pups deploying intraventricular injections of saline (as control) or ICG. Analysis of …

Sex Differences In Brain Iron Deposition And Microglial Ferritin In Alzheimer’S Disease

Faculty, Staff and Student Publications

Objective

Iron is the most abundant metal in the human brain, and plays a crucial role in many biological processes. However, disruptions in brain iron metabolism can lead to iron buildup, which occurs with aging and is linked to several brain disorders, including Alzheimer's disease. Microglia, the brain's resident immune cells, have the highest capacity to store iron, which is stored intracellularly within ferritin complexes. Importantly, women are at a higher risk of developing Alzheimer's disease and experience faster disease progression compared to men.

Methods

We used postmortem brain samples from patients with Alzheimer's disease and small vessel disease patients …

“No One Told You Life Was Gonna Be This Way”: A Qualitative Exploration Of Friendship Expectations And Reality In University Life, Michael Priestley, Hannah Rachael Slack, Miss Madiha Islam, Delia Fuhrmann, Emily Long, Sarah Crook, Juliet Foster, Sophie Homer, Nicola Byrom

School of Psychology

Introduction: Young adulthood (ages 18–25) is a high-risk period for loneliness, particularly during educational transitions. Loneliness has negative consequences for mental health, physical health, and educational achievement. Psychologists conceptualize loneliness as emerging from a discrepancy between expected and experienced social connection, but this has been under-explored during young adulthood. Method: Drawing on thematic analysis of eight focus groups with 21 young adults in the UK, this paper explores the differences between retrospective expectations and experience of social connection during the transition into university and the implications for loneliness. Results: Whilst social expectations, experiences, and preferences vary considerably, young adults' perception …
