Item A Novel Approach to Inquiry-Based Learning Models in the Sciences: Utilization of Case Presentations and Patient Encounter Workshops in High School Life Science Classrooms(2004-07-01) Whitaker, Lekeisha R.; Rustin E. Reeves; Victoria Rudick; Rouel RoqueA Novel Approach to Inquiry-Based Learning Models in the Sciences: Utilization of Case Presentations and Patient Encounter Workshops in High School Life Science Classrooms. Lekeisha R. Whitaker. Abstract. A novel approach to inquiry-based learning models is needed in a curriculum that reflects changing demographics, societal demands, and diverse cultural background. The proposed module which is designed to teach the urinary system to Fort Worth Independent District high school biology students as outlined in the Texas Essential Knowledge and Skills (TEKS) guide, represents application of this novel tool in the classroom. It is designed to be implemented in inquiry-based learning classrooms that function to encourage the natural process of inquiry throughout grade levels. The proposed module takes advantage of media resources, introductory case reports, and patient encounter workshops that outline diet, disease, and health disparities as a way to capture student interest in content relevant material, engage students in the daily lessons, and invoke long-term retention of basic life science concepts. Through future research and testing of module design and effectiveness in the classroom, the proposed approach to inquiry-based learning may serve to optimize student understanding of fundamental science concepts and diet and disease as it relates to normal body function, with implications that may affect change in lifestyle. Furthermore, the proposed learning module, if effective, may also serve as a template to be used to teach other life science subjects.Item Adipose Tissue-Derived Mesenchymal Stem Cells(MDPI, 2021-12-06) Bunnell, Bruce A.The long-held belief about adipose tissue was that it was relatively inert in terms of biological activity. It was believed that its primary role was energy storage; however, that was shattered with the discovery of adipokines. Scientists interested in regenerative medicine then reported that adipose tissue is rich in adult stromal/stem cells. Following these initial reports, adipose stem cells (ASCs) rapidly garnered interest for use as potential cellular therapies. The primary advantages of ASCs compared to other mesenchymal stem cells (MSCs) include the abundance of the tissue source for isolation, the ease of methodologies for tissue collection and cell isolation, and their therapeutic potential. Studies conducted both in vitro and in vivo have demonstrated that ASCs are multipotent, possessing the ability to differentiate into cells of mesodermal origins, including adipocytes, chondrocytes, osteoblast and others. Moreover, ASCs produce a broad array of cytokines, growth factors, nucleic acids (miRNAs), and other macromolecules into the surrounding milieu by secretion or in the context of microvesicles. The secretome of ASCs has been shown to alter tissue biology, stimulate tissue-resident stem cells, change immune cell activity, and mediate therapeutic outcomes. The quality of ASCs is subject to donor-to-donor variation driven by age, body mass index, disease status and possibly gender and ethnicity. This review discusses adipose stromal/stem cell action mechanisms and their potential utility as cellular therapeutics.Item Dr. Joseph Warren(2013-08-02)Item Silvey, J.K.G., Ph.D.(1980-12-19) Silvey, J.K.G.; Stokes, C. RayRetired chairman of the North Texas State University department of biological sciences, Dr. Silvey was appointed TCOM’s first director of basic sciences in 1972 and served as associate dean of TCOM in 1975-76. He relates his role in establishing the first working agreement with NTSU for the basic science instruction of TCOM students, which eventually led to the complete affiliation of the two schools. He discusses the many roadblocks that had to overcome. Interviewed by C. Ray Stokes, December 19, 1980
