Shedding light on dark truths : the evolution of African American history at Tryon Palace in New Bern, NC

Tryon Palace was home to the first royal governors of North Carolina. Today, the site is one of the most visited historic sites in the state. But what stories are visitors hearing? The historic homes and buildings at the site display local history but African Americans have only recently penetrated the interpretation.   This thesis acknowledges the difficulties of displaying topics that are sensitive and emotional for many audiences while investigating the tremendous amount of African American history surrounding Tryon Palace. The town of New Bern, NC has always maintained a diverse population and African Americans have played a significant role in the town's history. Yet many are unfamiliar with this complex and unique story. This history both parallels and intersects with Tryon Palace in different eras.   Using various primary and secondary sources, this thesis serves as a case study on how local African American history is interpreted at historic sites and museums. Much of the changes can be attributed to the African American Research Project, which was implemented in 1999. This endeavor created programs that brought African American history to the forefront of Tryon Palace's interpretation.  M.A

Are hygiene standards useful in assessing infection risk?

We monitored the surface level cleanliness of a five-bedded surgical intensive care unit (SICU) over a ten-week period in order to evaluate proposed hygiene standards.Ten environmental sites within SICU were sampled twice weekly along with collection of clinical and patient activity data. The standards designate aerobic colony counts (ACCs) >2.5cfu/cm2 from hand-touch sites and the presence of Staphylococcus aureus as hygiene failures. Nearly a quarter of 200 samples failed the standards, mostly from hand-touch sites on curtains, beds and medical equipment. The total number of fails each week was associated with bed occupancy (p=0.04), trending towards association with SICU-acquired infections (p=0.11). Environmental S.aureus was associated with the proportion of beds occupied (p = 0.02). Indistinguishable genotypes were found between patient and environmental staphylococci, with timescales supporting staphylococcal transmission in both directions. Hygiene standards based on microbial growth levels and the presence of S.aureus reflect patient activity and provide a means to risk manage infection. They also exposed a staphylococcal reservoir that could represent a more tangible risk to patients. Standards for surface level cleanliness deserve further evaluation

Genomic Data Analysis of SARS-Cov-2 Variants and Trends

The objective of this study was to analyze SARS-Cov-2 sequence variants and trends during the pandemic. This study was done using SARS-Cov-2 positive patient samples from Boise State University and the surrounding community. For variant analysis, Next Generation Sequencing was performed and the sequences were analyzed using the DRAGEN COVID Lineage (version 3s) pipeline on Illumina’s BaceSpace software. Any sequences with low-quality control were removed from the data. Some of the factors that were analyzed included symptoms by clade, campus positivity rates and the amount of campus and community tests run each semester. Individuals from the Boise State campus were identified as off-campus students, on-campus students, or faculty/staff members. The COVID sequencing data was also analyzed against key demographics such as an individual’s gender, age, race, ethnicity, and location. Sequences were also organized by the phylogeny of clades found from 2020-2024

Management of vaginal wall perforation during a second trimester dilation and evacuation

Background: We report an unusual case involving vaginal perforation associated with second trimester dilation and evacuation. Review of the literature fails to identify additional reports. Case: A 22 year G3P1011 female at 16 weeks gestation referred for evaluation following incomplete dilation and evacuation was found to have vaginal perforation, and communication with the peritoneal cavity on pelvic examination. Examination under anesthesia and laparoscopy confirmed multiple vaginal perforations with intraperitoneal defects and hematomas but no viscus involvement. Cervical dilation was accomplished with osmotic dilators placed under ultrasound guidance during exam under anesthesia, with evacuation completed approximately 16 hours later without further complication. Conclusion: This is the first case of vaginal perforation at time of dilation and evacuation reported in the literature. Laparoscopy should be performed to evaluate for intraabdominal injury to bowel, bladder and/or blood vessels. Use of osmotic dilators during the second trimester could potentially decrease the risk of vaginal perforation during the dilation portion of the procedure

Conservation of Sagebrush Ecosystems Through Diet Analysis of an Obligate Species

Sage Grouse (Centrocercus urophasianus) is an obligate species that depends on sagebrush to survive and serves as an indicator species and umbrella species for the sagebrush ecosystem. The sagebrush ecosystem has been declining rapidly therefore understanding the impacts on Sage Grouse could aid researchers and land managers in best practices to protect the long-term viability of the species, the ecosystem, and 350 other species that depend on it, including humans. One way to understand these impacts is through dietary indicators, such as the availability of preferred forage plants. In the past, this has been done by direct observation, which requires many hours in the field, and crop dissection, which involves collecting carcasses. These are both time-consuming and costly. Recent advances have shown that diet can be more easily and accurately determined through the sequencing of plant DNA in fecal samples targeting the ITS2 gene of plants. My project involves extracting plant DNA from fecal samples, optimizing a primer set for PCR of the ITS2 gene, performing DNA barcoding using next-generation sequencing, and comparing the results with reference genomes of plants

Loss of mDia1 and Fhod1 impacts platelet formation but not platelet function

An organized and dynamic cytoskeleton is required for platelet formation and function. Formins are a large family of actin regulatory proteins which are also able to regulate microtubule dynamics. There are four formin family members expressed in human and mouse megakaryocytes and platelets. We have previously shown that the actin polymerization activity of formin proteins is required for cytoskeletal dynamics and platelet spreading using a small molecule inhibitor. In the current study, we analyze transgenic mouse models deficient in two of these proteins, mDia1 and Fhod1, along with a model lacking both proteins. We demonstrate that double knockout mice display macrothrombocytopenia which is due to aberrant megakaryocyte function and a small decrease in platelet lifespan. Platelet function is unaffected by the loss of these proteins. This data indicates a critical role for formins in platelet and megakaryocyte function

Life course body mass index and risk of knee osteoarthritis at the age of 53 years: evidence from the 1946 British birth cohort study

Introduction: The authors examined how body mass index (BMI) across life is linked to the risk of midlife knee osteoarthritis (OA), testing whether prolonged exposure to high BMI or high BMI at a particular period has the greatest influence on the risk of knee OA. Methods: A population-based British birth cohort of 3035 men and women underwent clinical examination for knee OA at age 53 years.Heights and weights were measured 10 times from 2 to 53 years. Analyses were stratified by gender and adjusted for occupation and activity levels. Results: The prevalence of knee OA was higher in women than in men (12.9% (n=194) vs 7.4% (n=108)). In men, the association between BMI and later knee OA was evident at 20 years (p=0.038) and remained until 53 years (OR per z-score 1.38 (95% CI 1.11 to 1.71)). In women, there was evidence for an association at 15 years (p=0.003); at 53 years, the OR was 1.89 (95% CI 1.59 to 2.24) per z-score increase in BMI. Changes in BMI from childhood in women and from adolescence in men were also positively associated with knee OA. A structured modelling approach to disentange the way in which BMI is linked to knee OA suggested that prolonged exposure to high BMI throughout adulthood carried the highest risk and that there was no additional risk conferred from adolescence once adult BMI had been accounted for. Conclusion: This study suggests that the risk of knee OA accumulates from exposure to a high BMI through adulthood. <br/

Emerging Gene-Editing Modalities for Osteoarthritis

Osteoarthritis (OA) is a pathological degenerative condition of the joints that is widely prevalent worldwide, resulting in significant pain, disability, and impaired quality of life. The diverse etiology and pathogenesis of OA can explain the paucity of viable preventive and disease-modifying strategies to counter it. Advances in genome-editing techniques may improve disease-modifying solutions by addressing inherited predisposing risk factors and the activity of inflammatory modulators. Recent progress on technologies such as CRISPR/Cas9 and cell-based genome-editing therapies targeting the genetic and epigenetic alternations in OA offer promising avenues for early diagnosis and the development of personalized therapies. The purpose of this literature review was to concisely summarize the genome-editing options against chronic degenerative joint conditions such as OA with a focus on the more recently emerging modalities, especially CRISPR/Cas9. Future advancements in novel genome-editing therapies may improve the efficacy of such targeted treatments
