Development Of A Procedure For Prion Surveillance In The Laboratory Setting, Damian Gorski, Isaac Schauer, Kane Spicker, Ananya Tupaki-Sreepurna, Fei Wang, Claudio Soto, Sandra Pritzkow

Faculty, Staff and Student Publications

Infectious prions readily adhere to common surfaces, retain infectivity, and are highly resistant to conventional decontamination, posing significant biosafety challenges in the medical and research environments. Recent occupational exposures underscore the urgency of improving safety measures. Here, we describe an approach combining foam-swab surface sampling and protein misfolding cyclic amplification to enhance prion surveillance. Our results demonstrate the ability to detect prions most relevant to human health directly from contaminated surfaces, even at 100 million-fold dilutions of the brain. We applied our method to assess the completeness of prion decontamination and show that high prion quantities can resist even approved …

Integrated Chitosan-Based Coagulation And Microbubble Pre-Treatment For Improved Microplastic Fibre Removal From Water, Nimesha Thathsarani, Mohadeseh Najafi, Mehdi Khiadani, Muhammad Rizwan Azhar, Masoumeh Zargar

Research outputs 2022 to 2026

Microplastic fibres (MPFs) dominate treatment plant influents but are difficult to remove due to their morphology, composition and low density, limiting the effectiveness of coagulation flocculation pre-treatment. Integrating coagulation-flocculation with microbubble introduction offers a sustainable route to improve MPF removal, yet conventional inorganic coagulants often require high dosages, show strong pH dependence, and pose environmental risks. Chitosan is a biodegradable and non-toxic green alternative, but its application is limited due to its low solubility and pH sensitivity. In this study, two amphoteric derivatives of Chitosan have been successfully developed: CMC-CTA, produced by modifying carboxymethyl Chitosan (CMC) with 3-chloro-2-hydroxypropyl trimethyl ammonium …

The Common Cold Is Associated With Protection From Sars-Cov-2 Infections, Camille M Moore, Katherine Rivera-Spoljaric, Et Al.

2020-Current year OA Pubs

BACKGROUND: Adults and children often respond differently to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, with adults facing a higher risk of symptomatic and severe illness. We hypothesize that children's protection from symptomatic SARS-CoV-2 may be due to more frequent respiratory viral infections, which prime their airway antiviral defenses.

METHODS: Using case-cohort and case-control analyses in the Human Epidemiology and Response to SARS-CoV-2 cohort, we evaluated whether infection with common respiratory viruses protects against SARS-CoV-2 infections and investigated airway molecular mechanisms by which this protection is achieved. We tested 10 493 longitudinal nasal swabs from 1156 participants for 21 …

Counselor Education And Inclusive Postsecondary Education: A Partnership Model, Rebecca B. Smith Hill, Alexander M. Fields, Olivia J. Lewis, Madeline Saunders, Chelsea Stinnett, Anthony Plotner, Rachel Gilreath

Teaching and Supervision in Counseling

Researchers in the counseling field have alerted practitioners and counselor education professionals to the need for enhanced training related to supporting individuals with disabilities, namely intellectual and developmental disabilities (IDD; Feather & Carlson, 2019). As more individuals with IDD attend college, these emerging adults are specifically in need of counselors with skills and competencies to support their mental health. This paper describes a collaborative, mutually beneficial initiative between a counselor education program and an inclusive postsecondary education program to address the scarcity of personnel prepared to work with individuals with IDD.

Mental Health Professionals’ Non-Clinical Roles As Informed By Attachment: A Systematic Review Of Research, Jennifer L. Tipton, Casey A. Barrio Minton, Brittney N. R. Irion

Teaching and Supervision in Counseling

While attachment informs the quality of the therapeutic relationship, which is the basis of all therapeutic work for professional counselors and related mental health professionals (MHPs), less attention has been given to the role of attachment in MHPs’ non-therapeutic roles such as engagement in professional development, teaching, and supervision. This systematic review analyzed 33 research studies that investigated MHPs’ attachment in the context of non-therapeutic roles, including professional development, supervision, and teaching. Findings are discussed in the context of four emergent themes: Professional Functioning and Well-being, Supervisory Relationships, Self-awareness, and Empathy. There is considerable evidence that MHP attachment style is …
