Hepatitis C Treatment Initiation During Hospitalization For People Who Use Drugs: A Narrative Review Of The Literature, Jacob Denkins, Jane Babiarz, Youngyoon Ham, Hayoung Ryu, Brian Ricci, Carissa Williams, Ian Alexander, Kendall Tucker, L Madeline Mccrary, Ximena Levander

2020-Current year OA Pubs

People who use drugs (PWUD) are increasingly acquiring and transmitting hepatitis C virus (HCV) and being admitted to the hospital for often costly non-HCV-related conditions. Traditionally, treatment of HCV has been deferred to the outpatient setting. However, outpatient HCV follow-up can be an arduous process to navigate with resultant gaps in care, especially for PWUD with numerous complex psychosocial and medical comorbidities. Hospitalization presents a key opportunity to initiate treatment, and several institutions have piloted inpatient treatment models with intensive outreach. We conducted a narrative review of peer-reviewed literature (2014-2024) evaluating hospital-based HCV treatment models for PWUD; 6 studies from …

Biomolecular Condensates In Immune Cell Fate, Srikanth Kodali, Caroline M Sands, Lei Guo, Yun Huang, Bruno Di Stefano

Faculty, Staff and Students Publications

Fate decisions during immune cell development require temporally precise changes in gene expression. Evidence suggests that the dynamic modulation of these changes is associated with the formation of diverse, membrane-less nucleoprotein assemblies that are termed biomolecular condensates. These condensates are thought to orchestrate fate-determining transcriptional and post-transcriptional processes by locally and transiently concentrating DNA or RNA molecules alongside their regulatory proteins. Findings have established a link between condensate formation and the gene regulatory networks that ensure the proper development of immune cells. Conversely, condensate dysregulation has been linked to impaired immune cell fates, including ageing and malignant transformation. This Review …

The House At The End Of Time, Gyles Jose Antonio Ferrao

Masters Theses

This thesis investigates the architectural potential of thresholds as spaces of psychological and metaphysical transformation, positioning the edge not as a boundary but as a generative spatial condition. Drawing upon Carl Jung’s conception of dream architecture as a symbolic map of the self, the project proposes a nonlinear exploration of architecture through layered references that operate across metaphysical scales. The house becomes a medium through which the liminal is made tangible, a temporal and spatial construct that blurs the binary oppositions of life and death, memory and forgetting, reason and absurdity, consciousness and the unconscious.

The project conceptualizes architecture as …

Analytical Approaches For Identification Of Essential Genomes Of Plasmodium Knowlesi And Babesia Divergens, Sida Ye

Graduate Doctoral Dissertations

Apicomplexa constitute a large phylum of single-celled, obligate intracellular protozoan parasites. Notably, Plasmodium spp. and Babesia spp. are apicomplexan parasites that infect red blood cells. Plasmodium species are the causative agent of malaria and are transmitted by Anopheles mosquitoes, affecting large human populations, whereas Babesia spp., transmitted through the bite of Ixodes ticks cause babesiosis.

In this dissertation, we investigate the essential genome of these parasites using high-throughput transposon mutagenesis. Identifying the essential genome is key to finding new drug targets and understanding resistance mechanisms, a crucial pursuit given the rising resistance to frontline antimalarial drugs and the challenges …

Russell’S Viper Envenomation: The Challenge Of Diagnosis, Jing-Hua Lin, Wang-Chou Sung, Jiunn-Wang Liao, Dong-Zong Hung

BioMedicine

Russell’s viper envenomation is rare in Taiwan, and its typical clinical presentations, including consumption coagulopathy, acute renal failure, haemolysis, and increased capillary permeability, have been reported in the literature as case reports or series. Here, we report a case with an atypical presentation, and suspected to be a Russell’s viper bite due to the distinct characteristics of the snake and some progressive clinical signs/symptoms. He returned to health successfully after the correct antivenom was administered, and envenomation was ultimately confirmed by venom detection in the patient’s serum and urine samples.
