Through The Lens Of Time: Capturing The Ephemeral Magic Of The Circus, Rebecca Fitzsimmons

Faculty and Staff Publications – Milner Library

Images in the Charles Clarke Circus Photographs Collection document the Ringling Bros. and Barnum & Bailey Circus in the 1920s. Clarke, a leaper in the world-renowned aerial act, The Clarkonians, would have been in a relatively unique position to capture views of the circus from the vantage point of an insider. The resulting images carry the weight of that perspective. The photographs document important aspects of the circus, showing performers like Lillian Leitzel and May Wirth, spectacle wardrobe, practices and performances in the ring, and quieter moments behind the big top.

Acute myeloid leukemia (AML) is a hematologic malignancy for which allogeneic hematopoietic cell transplantation (allo-HCT) often remains the only curative therapeutic approach. However, incapability of T cells to recognize and eliminate residual leukemia stem cells might lead to an insufficient graft-versus-leukemia (GVL) effect and relapse. Here, we performed single-cell RNA-sequencing (scRNA-seq) on bone marrow (BM) T lymphocytes and CD34+ cells of 6 patients with AML 100 days after allo-HCT to identify T-cell signatures associated with either imminent relapse (REL) or durable complete remission (CR). We observed a higher frequency of cytotoxic CD8+ effector and gamma delta (γδ) T cells in …

Drug Modification Of Synaptic Plasticity At The Inhibitory Synapses Involving Gaba Neurons In The Ventral Tegmental Area, Jie Wu

Theses and Dissertations

The neurobiological underpinnings of substance use disorders (SUDs) involve complex alterations in synaptic plasticity within the mesolimbic dopamine system, particularly within the ventral tegmental area (VTA). While dopamine neurons in the VTA are extensively studied in addiction research, less attention has been given to the plasticity exhibited by VTA GABAergic neurons, despite their established regulatory role in modulating dopamine cell activity. Building upon the ground-breaking work of Bocklisch et al. (2013), we investigated the plasticity at the GABAergic to VTA GABA neuron (VTA GABA-to-GABA) synapse utilizing whole-cell electrophysiology in GAD67 GFP knock-in mice. Our findings revealed an exceptionally rare duo-plasticity …
