Factors Influencing Mortality Of Bighorn Sheep (Ovis Canadensis), Emily Moberg Jan 2023

Factors Influencing Mortality Of Bighorn Sheep (Ovis Canadensis), Emily Moberg

Electronic Theses and Dissertations

Reintroduced bighorn sheep (Ovis canadensis) in Nebraska faced a devastating pneumonia epizootic resulting in variable ewe reproductive success and poor lamb recruitment in many of the herds. From 2015-2017, no lamb recruitment was observed in the northern Pine Ridge subpopulation and as many as 60% of adults died. This was in stark contrast to the healthier Wildcat Hills herds to the south, where lamb recruitment was estimated to be between 50-70% during the same years. From 2018-2020, we radio-collared and recaptured 76 adult female bighorn sheep from 2 of 3 Pine Ridge herds and 1 of 2 Wildcat Hills herds. …

Turkish Journal of Biology

X-ray crystallography is a robust and powerful structural biology technique that provides high-resolution atomic structures of biomacromolecules. Scientists use this technique to unravel mechanistic and structural details of biological macromolecules (e.g., proteins, nucleic acids, protein complexes, protein-nucleic acid complexes, or large biological compartments). Since its inception, single-crystal cryocrystallography has never been performed in Türkiye due to the lack of a single-crystal X-ray diffractometer. The X-ray diffraction facility recently established at the University of Health Sciences, İstanbul, Türkiye will enable Turkish and international researchers to easily perform high-resolution structural analysis of biomacromolecules from single crystals. Here, we describe the technical and …

Differences In Phq-9 Depression Severity Between Adults Receiving Ketamine Or Ketamine-Assisted Psychotherapy, Sophie Lake Oswin Jan 2023

Differences In Phq-9 Depression Severity Between Adults Receiving Ketamine Or Ketamine-Assisted Psychotherapy, Sophie Lake Oswin

Walden Dissertations and Doctoral Studies

Treatment-resistant depression (TRD) affects roughly 2.8 million or 1.1% of the United States population. Many traditional treatments of mental disorders including various types of psychotherapy and pharmacotherapy do not provide adequate symptom reduction for clients, and many clients diagnosed with TRD seek out nontraditional treatments such as ketamine and psychedelics for their antidepressant effects. Due to the dissociative nature of psychedelic medication wherein resistance is reduced, and a trance-like state is induced, ketamine-assisted psychotherapy (KAP) has great potential as an adjunct to ketamine therapy. Procedures of KAP have been in development for the last 7 years and a consensus on …
