Message from the Chair Each year the predictable cycle of courses taught, experiments planned, comDr. Rena D'Souza mitee meetings scheduled and professional meetings attended is interwoven with the unique, innovative and sometimes unpredictable events that occur every year as we strive to meet our goals. This past year was no different in the Department of Biomedical Sciences (BMS): it included a mixture of the familiar structure of teaching, research and service responsibilities and within each of those realms, new innovations and ways of doing things that kept our teaching, research and service activities in step with and in some cases, a step ahead of other biomedical sciences groups. This newsletter reports on such activity in 2009 and early 2010 in the Department of Biomedical Sciences. The big picture tells us that academic dentistry is threatened and at the crossroads. Hence, departments like BMS serving as hubs for biomedical research in dental schools must

assume greater responsibilities. BMS faculty recognize that the new knowledge created through original research provides the framework for clinical applications in dentistry and medicine and that such information is critical for evidence-based decision-making in clinical settings. To transform a fairly traditional curriculum, our faculty have spearheaded many activities by taking knowledge generated from basic, translational and clinical research to the classroom and clinics. We are proud that we are part of this cycle of transformation and pleased that we have engaged students at all levels of development as well as our clinical faculty colleagues. The year was also marked with many achievements in grant funding, as several faculty were successful in obtaining support through the American Recovery and Reinvestment Act of 2009. These awards helped us mentor high school science teachers (see page 9) and dental student researchers (see page 4), enriched our current grant activities and created a new mechanism with the P30 award for us to recruit new faculty with expertise in

bioengineering (see page 10). As technology continues to change our lives on an almost daily basis, its application to the classroom brings new challenges and opportunities. The availability of course material via Camtasia and Blackboard has transformed students' learning experiences, and now the entry of dental education into “Second Life” offers another learning experience through virtual dental Grand Rounds (see page 3). Our goal for each year should be to make what is good even better in all areas of our activity. We succeeded in 2009 in this regard and look forward to the opportunities during 2010 to advance our teaching, research and service contributions to HSC - Baylor College of Dentistry. I am most grateful for the support and mentorship of the Dean, Dr. James Cole - without his help I would have not have grown professionally and personally in this role. I also remain proud to work with a tremendously talented and dedicated group of individuals within and outside BMS.

Virtual Dental Grand Rounds Dr. Bob Hutchins, Associate Professor in Biomedical Sciences, and Dr. Bill Wathen, Associate Professor in General Dentistry, are setting sail into uncharted virtual waters. They have teamed up with faculty at the University of Kentucky College of Dentistry to create a learning experience that no other dental school in the world has done: they are planning virtual dental grand rounds that third- and fourth-year students at multiple dental schools can tap into to learn about real-life dental scenarios using online technologies. The overall objective of this exercise is to support integrated basic and clinical information in a discussion of patient treatment needs. Using an online 3D virtual world called "Second Life (SL)", Dr. Hutchins and colleagues have begun to develop a grand rounds dental experience. They envision inviting clinicians in various specialties to present important, evidence-based issues as the sub-

nications over the Internet.

ject matter of each grand round. Basic science faculty will participate to provide foundational support for the integration of the subject matter. The format to be used will include several short segments modeled after the Burton and Roth grand round format (N Engl J Med 340:1516, 1999). For the pilot grand round, a clinical faculty member at each participating school will coordinate a group of 3-5 students, and an SL expert will oversee the meetings and assist with the guest speakers. The participants will communicate primarily via the computer keyboards; the speakers' presentations will be transmitted using microphones to allow voice commu-

After further work piloting this effort, the virtual grand rounds at Baylor College of Dentistry may evolve into a dental course selective that meets once a month. The ability to bring together colleagues at distant locations and provide an exchange of information would, according to student surveys, provide a unique learning experience not currently available at other dental schools. This use of a "virtual world" has already been adopted at other U.S. dental schools. The use of SL as a training tool for the delivery of educational content is now a part of the curriculum at the dental schools of the University of Maryland and Case Western Reserve University. For example, at the University of Southern California School of Dentistry, students have the opportunity to test their decisionmaking skills with interactive virtual patients. Because of the work of Dr. Hutchins and colleagues, Baylor College of Dentistry will soon join the list of American dental schools making greater use of technology to teach the curriculum. They are looking into the future, and the future looks "virtual."

BMS Faculty Contribute to Evidence-based Dentistry Efforts at BCD Members of BMS and other BCD departments forge ahead to integrate evidence-based dentistry (EBD) into the dental curriculum in a program supported by an NIH R25 grant called "Clinicians Using Science Produce Inspired Dentists" or "CUSPID�. The aims of this initiative, if achieved, will result in a graduating dentist who is better equipped to analyze and filter the massive amount of information to which he/she will be subjected and to decide whether and/or how to incorporate this information into the treatment of patients. Further, these efforts may be able to excite a small subset of DDS students to

enter into academic dentistry and/or clinical research. In keeping with the goal of implementing this evidence-based dentistry curriculum one year at a time, a new two-semester D2 course, Application of Evidence-Based Dentistry I, was introduced in Fall 2009 by the same faculty (Dr. Paul Dechow, Biomedical Sciences, and Dr. Hoda Abdellatif, Public Health Sciences) who direct the D1 EBD course. Several times per semester, each student participates in small group sessions led by these faculty, as well as Dr. Emet Schneiderman, in which they critique clinical research articles on topics selected to mesh with their

D2 pre-clinical coursework. At one session in each semester, each student prepares a Critically Assessed Topic (CAT) report based on a clinical scenario written by BCD clinical faculty and presents this report orally to his/her group and course faculty. An important feature of this course is the pairing of an EBD core faculty member and a clinical faculty member for each small group session. This approach has been very successful in providing a clinical perspective on the evidence presented, especially in the CAT. The faculty involved in this effort are encouraged by the results of a survey called PEAK (conducted by Dr. Ann McCann, BCD Director of Assessment) that assesses practices, continued page 4

experience, attitudes, and knowledge about EBD. The survey includes questions designed to document each participant’s habitual information sources, experience in reading and evaluating the dental literature and in research and related activities, attitudes about EBD and interest in clinical/ translational research, and a test of EBD knowledge based on a short research report. When PEAK was administered to D1 (EBDtrained) and D2 (EBD-naïve) students in Spring 2009, the trained D1 students indicated that they were more interested in learning about research careers (p<0.05) and teaching p<0.001) than the untrained D2 students and believed that EBD had changed the way they read clinical articles (p<0.001). In another EBD-related effort, BMS faculty members Dr. Robert Hinton

(contact PI for the R25 grant) and Dr. Robert Spears have taken the first step toward an expansion of the scope of BCD's traditional, basic science-focused Research Day to include topics and activities of interest to clinical faculty and D3-D4 students. The Research and Scholarship Day program held in April 2009 included clinical case presentations by four D3 and four D4 students in addition to the usual basic and translational research presentations. In 2010, they anticipate adding presentations by D2 students on the best of the CATs from Fall 2009. The faculty are optimistic that these changes will be instrumental in increasing the visibility of EBD-based efforts and start the process of greatly expanding the audience for this event to include most BCD students and faculty. Dr. Spears is also developing the Den-

page 4

tal Scholars Track, a four-year enrichment track for three entering D1 students that will provide them with a variety of research and teaching-related experiences characteristic of a dental academician. The three students chosen for 2009-2010 participated in faculty-mentored research projects in Summer 2009, and two of the three submitted AADR student research fellowship applications for 2010. They have also attended BCD seminars featuring speakers on developmental biology of the craniofacial region and craniofacial surgery, preceded by a journal-club discussion of one of the speakers’ articles. In the second year of this program, DS participants will attend a clinical research workshop as well as clinical research-related presentations at UTSouthwestern Medical School while continuing their summer research involvement.

Student Research is Alive and Very Well in BMS! Biomedical Sciences (BMS) becomes very busy during June and July each summer due to the influx of dental student research trainees who sign up to spend time in the lab of one of the BMS faculty members. They get hands-on training and experience in research techniques and protocols and are expected to present the results of their research at the annual meeting of the American Association for Dental Research (AADR) the following spring. The success of the student research program at Baylor College of Dentistry (BCD) is due in large part to the considerable efforts and devotion to the program by Dr. Robert Spears, Associate Professor. He and BCD were recently recognized by the AADR for having the most abstracts submitted to the annual meeting and also for having the most new members. BCD tied with the University of Michigan for these honors. Students at the graduate level perform research as part of their degree programs and also present their research at the International/American Associations for Dental Research

(IADR/AADR) annual meetings, as well as other professional society meetings. At the 2010 American Association for Dental Research meeting, several BCD students won awards for their work.

Anika Voisey

DDS/PhD student Anika Voisey (mentored Dr. Jerry Feng) was awarded 2nd place in the Senior Category, and Dr. Maria Serrano (menPaul Dyer tored by Dr. Kathy Svoboda) was a finalist in the Postdoctoral Category, of the prestigious AADR Hatton Awards competition. For her award, Ms. Voisey will be funded by the AADR to present her results at the IADR meeting in July 2010 in Barcelona, Spain. D2 student Paul Dyer (mentored by Dr. Svoboda) was awarded third place, and D2 student Karen Liang (mentored by Dr. Spears) was a final-

International Consortium Studying Early Hominid Feeding Biomechanics Meets at BCD Biomedical Sciences professor, Dr. Paul C. Dechow, hosted an international group of scientists investigating feeding ecology and biomechanics in early hominid evolution at Baylor College of Dentistry from December 2-6, 2009. The project is entitled "Integrative Analysis of Hominid Feeding Biomechanics" and is a collaborative effort among researchers from ten universities and colleges. This work was funded for $2,500,000 by a National Science Foundation Hominid Grant that runs from 2007 through 2012. The consortium is studying how the facial skeletons of human ancestors and some primates adapted to withstand the forces imposed by chewing. The group’s work is facilitated by daily electronic interaction and by an annual progress meeting. This year’s meeting, the second of the project, focused on the integrated investigations of the scientists, including studies of feeding ecology and behavior in wild living primates, laboratory studies of bone and muscle function during feeding in apes and other primates, detailed studies of the material properties and structure of the facial skeletons of living and fossil primates, computer-generated reconstructions of fossil hominid skulls, and the finite element studies of skull deformation and function in fossil hominids and related living anthropoids. In addition to three days of presentations and discussions, the group also toured the facilities at Baylor College of Dentistry and viewed demonstrations of ongoing work involving ultrasonic, mechanical, and MicroCT analyses of primate craniofacial bone, which is uniquely under investigation at BCD.

By examining the functional and evolutionary relationships between diet, skull form, and biomechanics, the researchers are formulating concepts relevant to dentistry and craniofacial medicine. They are also generating data relevant to conservation efforts by documenting the relationship between ecology and adaptation in certain primates.

from Dr. David Strait’s laboratory at the University of Albany, demonstrated her experiments involving in vitro loading of a chimpanzee cranium outfitted with a variety of strain gages and force sensors using a universal testing machine. Overall, the research is examining how the skull's shape has evolved in order to adapt to the forces associated with eating different types of food. It focuses on the skulls of the earliest human ancestors, which exhibit a collection of distinctive anatomical features in their jaws, faces, and teeth. These features have long been thought to be adaptations to feeding on very hard or resistant food objects, including nuts and seeds, which may have been critical for survival during periods of scarcity. Last year, the group further developed this thesis in an article published in the Proceedings of the National Academy of Sciences about corollaries between the mechanics of cranial structure and hard object feeding of so-called “fall-back foods” during periodic cycles of food scarcity. This article included the first finite element model and detailed mechanical analysis of the cranium of an early hominid, that of the famous South African gracile australopith-

In addition to the scientists from the Texas A&M Health Science Center Baylor College of Dentistry, the other project participants are from the University of Albany, the University of Chicago, George Washington University, Emory University, Mercer University, University of Massachusetts at Amherst, Kansas City University of Medicine and Biosciences, and The University of Vienna (Austria). The group will hold its third meeting on October 18-24, 2010, at the

Building Partnerships Several years ago, the Department of Biomedical Sciences (BMS) became involved in a partnership formed among a group of north Texas institutions including Baylor College of Dentistry (BCD) and the University of Texas Southwestern Medical Center. An important goal of this NIH-sponsored project, called the "Clinical and Translational Science Award" (CTSA) was to promote the transfer of laboratory discoveries to new therapies that improve human health. Other goals of this affiliation are training and mentoring clinical investigators, designing new informatics tools for clinical research and forming interdisciplinary teams in a variety of research areas. Drs. Paul Dechow and Lynne Opperman have leadership roles in the CTSA and participate in the development of clinical and translational research initiatives. More recently, BMS has been active in the formation of new partnerships near and far from Dallas. In September 2009, a group of BMS faculty members journeyed to Wuhan, China, to share scientific findings and discuss setting up a program between HSC-BCD and Wuhan University, in which PhD students from the Wuhan University College of Life Sciences may be accepted into the BCD Graduate Program to complete the course work and research requirements toward their PhDs. The Dean of the Wuhan University College of Dentistry will recommend students for this program who will apply for admission according to BCD's standard requirements. The faculty supervision and research support for these students will be provided by BCD during the students' course of study. Also, students seeking a degree from Wuhan University may be allowed to complete their research requirement at BCD with the approval of

bioengineering and translational research with a focus on tissue engineering. The Department of Bioengineering at UTA is a center for bioengineering studies in the Dallas-Fort Worth area and will provide opportunities for increased research collaborations not only with the new faculty, but also with the present BMS faculty.

Dr. Phillip Kramer speaks to a group at Wuhan University.

a BCD faculty mentor. In addition, each institution will promote the exchange of faculty as visiting professors and visiting scholars for teaching and for collaborative research programs. The proposed program will be valid for five years from the time it is formally finalized. Another new partnership recently formed between researchers in BMS and at the University of Pittsburgh is supported by American Recovery and Reinvestment Act administrative supplement funds. Mutual interest in the discovery of genes that cause or contribute to congenital tooth agenesis in humans is driving this partnership between Drs. Rena D'Souza and Gabriele Mues at BCD and Drs. Alexandre Vieira and Mary Marazita at the University of Pittsburgh School of Dental Medicine. Faculty at both institutions plan to collaborate on candidate gene sequencing and genome-wide association studies, which may be extended to include other craniofacial abnormalities that share similar genetic and developmental backgrounds. The successful funding of an NIH P30 grant awarded to BCD is opening up an avenue of affiliation with the College of Engineering at the University of Texas, Arlington (UTA). This grant provides support for the hiring and development of two new faculty members with expertise in

Several Biomedical Sciences faculty members participated in the Reconstructive Surgery Summit held in Dallas on November 14, 2009. In addition to bringing the participants up to date on innovative areas in reconstructive and regenerative surgery, the meeting gave BMS faculty a great opportunity to begin collaboration with outstanding clinicians in this exciting area of translational research. The meeting was hosted by Dr. Kenneth Salyer, Adjunct Professor in BMS and Founder and Chairman of the World Craniofacial Foundation. Dr. Frank Papay of the Cleveland Clinic presented his teamâ&#x20AC;&#x2122;s experience performing the first successful face transplant in the U.S. in 2009. Dr. Gino Rigotti of Verona Hospital Institutes in Italy and Dr. Sydney Coleman of New York University presented their extraordinary results using adipose-derived stem cells in breast reconstruction following cancer surgery. From BMS, Dr. Gabriele Mues, Assistant Professor, spoke on clinical applications of genetics in human malformations. Dr. Jerry Feng, Professor, presented a talk about the manipulation of BMP receptors to regenerate craniofacial defects. Dr. Emet Schneiderman, Associate Professor, spoke on the potential for cone-beam computed tomography to resolve some of the long-standing controversies in cleft lip and palate repair. This meeting underscored the fact that collaborations will be one of the keys to further advancements in this important area.

Dr. Rena D'Souza, Ben Doolan (center) and Dusty Vincer

The summer of 2009 was unique in the Department of Biomedical Sciences. Besides the usual group of firstyear dental students performing research experiments under the guidance of BMS faculty, two high school science teachers were selected from a pool of 10 applicants to spend 10 weeks broadening their scientific expertise at Baylor College of Dentistry. Ben Doolan, a chemistry teacher at South Garland High School, and Dusty Vincer, a biology teacher in the Plano Independent School District, worked in the laboratories of Dr. Jerry Feng and Dr. Rena D’Souza, respectively where they explored the developmental biology of teeth, bones, and other structures forming the head and face. The internships, which included a $14,000 summer stipend for each teacher, were two of 54 dental research training positions supported nationwide by the NIH/National Institute of Dental and Craniofacial Research. D’Souza noted that these internships offered a telling example of how even a modest, short-term investment can have a tremendously catalyzing effect within a community, starting with the lives of the

High School Science Teachers in the Labs teachers themselves. For example, Doolan entered a six-year Ph.D. program in cell and molecular biology at the University of Texas at Austin in 2002. By the four-year mark, he had married, his wife expected their first child, and their credit card debt had reached $10,000 to cover basic living expenses. He reached a pragmatic but reluctant decision to take a job as a financial planner and then two years later, to become a high school science teacher in order to bring home a steady paycheck. Although teaching has worked out well for him, he still thinks about having never achieved his goal of getting a Ph.D. He says that when the opportunity at BCD arose, he started thinking that maybe he could still complete the journey. D'Souza left the door open: "If Ben can take time off for a sabbatical, we will be glad to let him continue with his Ph.D. training.” Vincer, who has been a science teacher for five years and was a biology major in college, spent her 10 weeks performing bench research and assisting on projects exploring the genetics and molecular biology of tooth bud formation. “To be quite honest, I’m not very familiar with the biology of tooth formation,” she commented. “So I can learn about the formation of the different tissues that comprise the head and face, and then I can take all of

that back to my students.” Among her administrative duties, Vincer helps to develop the science curriculum for the Plano Independent School District. “Our ninth graders participate each year in a science fair,” she said. “They’re really just scratching the surface with some of the projects, but this training grant will allow me to make a connection with a respected local scientific organization. If a student is interested in a science fair project to show, for example, how a tooth or a face forms, I can pick up the phone, call Baylor College of Dentistry, and find a knowledgeable professional to help nurture their curiosity.” “So often we talk to kids in the classroom about genes and proteins, but our words have no tangible connection to anything that’s real to them,” said Doolan. “Dr. D’Souza has talked about bringing some of her group into the classroom to show the kids, say, a frog that produces a green fluorescently labeled protein or some of the other really cool stuff they work with every day. They can tell the students, ‘Here, hold this or look at that. This is the really cool part of what we do.’ Hopefully, their realworld enthusiasm can inspire the students to become the researchers of the future.”

Mineralized Tissue Preparation Course Offered by BMS Faculty A course on modern methods of mineralized tissue preparation for light and scanning electron microscopy was held at Baylor College of Dentistry on June 15-19, 2009. The Preparation and Analysis of Mineralized Tissues was attended by 30 people, including students and instructors.  Of the 15 students in attendance, three were from outside BCD (Massachusetts, Georgia, Houston).  Course sessions included presentations on Sample Preparation for Scanning and Light Microscopy, Decalcification and In

Situ Hybridization Protocols, Microwave Energy and Tissue Processing - Current Thinking, and Introduction to and Demonstration of μCT. Presentations were given during Lunch and Learn sessions by Baylor College of Dentistry faculty; the topics included "Using Undemineralized Tissue in Translational Research" and "Application of μCT to Mineralized Tissue Evaluation." The participants enjoyed the handson experience combined with the lectures on detailed descriptions

of how the techniques learned in the lab  could be  applied to various kinds of experiments.  Specific comments at the conclusion of the course included "Great course for all grad students", "Down-to-earth speakers! Very interesting topics.  I loved the hands-on instruments plus the PowerPoint presentations... The manual was very organized and impressive."  One participant reported that, after returning to her institution, she gave a presentation to a group there on several of the things she had learned in the continued page 10

Biomedical Sciences Awarded Funding to Hire Bioengineers Texas A&M Health Science Center Baylor College of Dentistry (HSCBCD) was one of only seven institutions in the nation to be awarded grant funding for hiring two new faculty members in bioengineering sciences and translational research. The American Recovery and Reinvestment Act (ARRA) provided the funds awarded by the NIH/National Institute for Dental and Craniofacial Research through the "P-30" grant mechanism. This $1.4 million, two-year project called “B-BEST” (Baylor’s Program in Bioengineering Sciences and Translational Research) could help transform laboratory findings into dental practices. Dr. Rena D'Souza, professor and chair of biomedical sciences, is the project's principal investigator, and Drs. Paul Dechow and Larry Bellinger serve as co-investigators. A team composed of leaders within the field of tissue engineering (Drs. Pranesh Aswath, UT Arlington; Paul Krebsbach, University of Michigan; Antonios Mikos, Rice University; David Mooney, Harvard University) will advise the project’s recruitment and development. The long-term objective of B-BEST

is to enhance HSC-BCD’s capacity for translational research in order to develop innovative oral health care treatments. It will increase oppor-

Drs. Larry Bellinger, Rena D'Souza and Paul Dechow

tunities for collaboration with biomedical engineering researchers at UT Arlington and Southern Methodist University, and with clinical and translational science researchers at the University of Texas Southwestern Medical Center. The grant will also develop training opportunities for predoctoral students and dentist-scientist graduates who are interested in bioengineering, translational, and patient-oriented research and academic careers. A faculty search is underway for bioengineers with extensive training in the regeneration of the mineralized and soft tissues of the cran-

iofacial complex. They will be hired as P30 faculty in tenure-track positions and cross-appointed within HSC-BCD in either the Periodontics or Oral Surgery departments. They also will be faculty in the Biomedical Engineering graduate program at the University of Texas at Arlington. HSCBCD’s network of basic, translational, and clinical researchers will collaborate with these new faculty to study new technologies for improved craniofacial and oral health care, including the development of biomimetic and nanostructured scaffolds, use of stem cells, and the delivery of bioactive factors and drugs for healing craniofacial diseases and traumatic injuries. The project’s leaders say this grant, along with six other ARRA-funded projects, marks a turning point for biomedical research at HSC-BCD. Within the dental research community, the successful funding of B-BEST puts the college at the forefront of translational research. For patients, the discoveries funded by it will lead to innovations in dental and craniofacial treatments for years to come.

course. The course was cosponsored by the Texas A&M HSC Vice President for Research and Graduate Studies,  the BCD Office of Research and Graduate Studies and by Ted Pella, Inc. The course will be presented again on June 7-11, 2010. As in the first presentation of the course, the broad topics covered will include Undecalcified Tissues, Tissue Analysis Techniques, Decalcified Tis-

sues, and Resin-embedded SEM. This course will be sponsored by the Department of Biomedical Sciences, the Office of Research and Graduate Studies, Baylor College of Dentistry, Ted Pella, Inc., and the American Association of Anatomists. Information about the course can be found at http://
