  • FLATFISH ASSEMBLAGE AND ABUNDANCE DIFFERENCES BETWEEN THE SAINT CATHERINES ISLAND AND SATILLA RIVER ESTUARIES

    St. Catherines Island is a pristine uninhabited barrier island off of the Georgia coast, and is believed to have experienced less anthropogenic alteration when compared to mainland estuarine habitats. In contrast, the Satilla River estuary has been historically affected by human activity, especially during the construction of navigational "cuts" through the marsh in the early 1900s. These cuts were used to support economic gain no longer in the area. Because of the differences in human influence, we hypothesize the fish assemblages will be different. We compared abundance of various resident flatfish species captured when trawling and using gill nets in these two systems. As benthic species, flatfish may be especially affected by anthropogenic disturbances of the estuarine substrates. This study provides insight into the effects of human disturbances on benthic fish species populations and assemblages. We compared catch-per-unit effort for six flatfish species between data among several sites, seasonally, between 2015 and 2018. We also looked at environmental variables when comparing abundance. The data are reflective of differences that exist in resident flatfish populations, and this condition could be explained by anthropogenic activities.
  • SERUM-C TERMINAL CROSSLINKING TELOPEPTIDE (CTX) AS A PREDICTIVE BIOMARKER OF BISPHOSPHONATE-RELATED OSTEONECROSIS OF JAW (BRONJ): SYSTEMATIC REVIEW AND META-ANALYSIS

    The aim of this systematic review was to evaluate the validity of using preoperative serum C-terminal crosslinking telopeptide (CTX) levels as predictive factor of increased risk of developing medication-related osteonecrosis of the jaw (MRONJ) in patients on bisphosphonate (BP) therapy who undergo invasive dental procedures. A search was conducted through PubMed, MEDLINE, and Web of Science, following PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Meta-analysis was conducted on the risk ratio. The methodological index for nonrandomized studies (MINORS) and Quality Appraisal of Reliability Studies (QAREL) checklist were used to assess quality. Eighteen clinical trials, involving 2301 patients were included. Most patients received Alendronate or Risedronate for an average of 62.14 months. The average serum CTX level in BP-treated patients before surgery was 217.67 pg/ml. Meta-analysis demonstrated that the cutoff in CTX level (150 pg/ml) was not predictive of BRONJ risk. The sensitivity of CTX value <150 pg/ml was 34.26% and the specificity was 77.08%. The use of CTX to diagnose BRONJ risk following dental procedures in bisphosphonate-treated patients is not justified. Further studies are needed to develop other reliable biomarkers.
  • EFFECTS OF CHRONIC ALOHOL AND GLUCOSE EXPOSURE ON VIABILITY OF ALVEOLAR MACROPHAGES

    The adverse health risks associated with alcohol abuse and obesity are widely known by the general population. Although lesser known, studies have presented the lungs as secondary organs affected by such lifestyle factors. Healthy lungs are protected against infection and harmful airborne particles by macrophages, the working entities of the immune system which fight potential sources of infection. When these immune-responsive cells are compromised and unable to perform their functions, lung health may deteriorate. Therefore, a healthy pulmonary alveolar macrophage population is vital for adequate lung function. Chronic alcohol abuse and obesity have been shown to suppress alveolar macrophage function, thus lowering the lungs� first line of defense. The objective of this study is to determine the effects of exogenous ethanol and increased glucose concentration on macrophage size and viability via an�in vitro�study on NR8383 rat alveolar macrophages. The study measures macrophage viability under treatment conditions.

    Jessica Smith Schwind, Learning is Contagious: Lessons in Online Course Design: Online learning environments are a key platform for teaching and learning in the 21st century, but they often try to simply recreate the classical in-person classroom. Our goal was to develop, implement and evaluate an immersive, online course where students are key players in a captivating epidemiologic outbreak investigation using a multidisciplinary team approach.; Thomas Weeks, Using threshold concepts in information literacy instruction: While "threshold concept" is a buzzword in information literacy instruction, can it be useful for single-session information literacy instruction? This project evaluated students who received instruction based in threshold concepts to see if they did better than their peers who received traditional skills-based instruction.; Nickie Reich, Lessons Learned From My First Son Project Traditional vs. Discovery Learning in College Algebra: Ms. Reich will step the audience through the planning, implementation, and analysis of her first So TL project. Knowledge gained from the experience and from the project data will be shared.; Melissa Johnson and Rhonda Armstrong, Using Freely Available Texts in a Literature Classroom: Rhonda Armstrong and Melissa Johnson will present their So TL project and discuss the challenges of creating an American Literature survey (pre-colonial to present) using freely-available texts. They will also discuss the students' attitude toward and level of engagement with digital texts.; Quentin Hartmann, Can peers improve performance? An investigation of the Think-Pair-Share teaching strategy: The Think-Pair-Share teaching strategy was tested with a class of psychology majors in a Senior Capstone course. All students did the same assignment alone, then one half of the students provided feedback to each other; the other half worked alone and all were given the option to revise their work. Performance between groups was compared.
