Tag: research-rich education
We had another BUSY week in Biomedical Science courses.
- Freshman-level BIMS 1300 Intro to Scientific Research students learned how to use their Tablet PCs to gather data from a “Brain Test” all students took (determined analytical vs. creative, auditory vs. visual) and calculate standard error of the mean, as well as linear regression analysis of data sets. In the lab, students finished up their observation projects that will be presented in the coming week.
- The new microbiology course for allied health majors, BIOL 3403 Fundamentals of Microbiology participated in a webinar hosted by McMurry alumna Mary Lynn Smith (’83) on biofilms in healthcare. This was an example of how experts and professionals a thousand miles away can contribute to our students’ education.
- In BIOL 3410 Microbiology, students finished the identification of Gram positive bacteria found in their cars. They are working on research posters describing their studies and will turn those in next week. In short, they took samples from the HVAC and interior surfaces of their cars, isolated and purified bacteria, and pursued identifications of the Gram positive cocci found using conventional tests and the BD-BBL Crystal(TM) Rapid ID panels. Follow-up tests included testing for oxacillin-resistance, an indicator of community-borne MRSA.
- In BIMS 4391 Advanced Microbiology, students moved forward in their development of antibiotic-producing bacteria. They completed the identification of their endospore-formers using microscopy, conventional tests, and BD-BBL Crystal(TM) Rapid ID panels. Then, they grew their bacterium in batch culture, removed the cells and spores by centrifugation and filtration, and challenged six microbes (two Gram negative rods, two Gram positive cocci, two yeasts) with the filtrate in disk diffusion tests. Those antibiotic producers with the most promise will be grown in our new benchtop fermenters and their products characterized by chemical, physical, and physiological means to learn more.
- In our BIMS 4201 Capstone Research class, senior students began cultivating the Saccharomyces cerevisiae strain genetically-modified with human estrogen receptor as a prelude to the use of the YES assay for monitoring the presence of estrogen-mimics in the environment.
All this may sound way beyond the reach of normal college students in normal college classes. Not so! We find that students are more engaged in learning techniques and information when there’s a reason or goal – a pot of gold at the end of the rainbow! It is at the heart of the skills-laden, research-rich approach taken in teaching BIMS courses.
One of the key elements of the BIMS program and its approach to giving students an experience-rich education was the intent to have all students complete a capstone experience. We felt many students would opt for on-campus projects with faculty but that some would take advantage of opportunities with summer research programs and biotech companies to apply their skills and knowledge in different settings. With the resources of the TTU School of Pharmacy’s graduate program in Abilene and biotech firms like Receptor Logic settling in here, it was only a matter of time before a student would complete their capstone work at one of those two venues. However, with a program only two years old, we felt it would be at least another year before this happened. Biology major Gina Ortiz surprised us all by choosing a BIMS capstone experience and working with TTU School of Pharmacy scientists this spring. She thereby becomes the first BIMS capstone student, and the first to complete the work in collaboration with an outside agency.
Ortiz, a Nevada resident, is headed for a career in medicine or biomedical research and used this experience to further hone in a direction to follow once she graduates this May – a year early. Her work was done at the School of Pharmacy in the lab of Dr. Jon Weidanz with direct supervision from his doctoral student Bhavna Verma. Her project was entitled “Biodistribution of RL4B TCRm antibody in mice models”. In her work, Gina became proficient in conducting enzyme-linked immunosorbent assays (ELISA) to screen whether therapeutic T-cell receptor mimics (TCR-m) used for fighting cancer tumors might target and bind healthy mouse tissues. Such information would be valuable in completing an overall picture of how TCR-mimics impact the biology of a patient when used in treatment.
Gina explained her research on Friday, April 30th before a group of students and faculty. Among them was McMurry’s president, Dr. John Russell, who was impressed by the quality of work and polish of her presentation. On behalf of all in BIMS, congratulations Gina on a job well done!
