Dr. Ignarro, the Jerome J. Belzer, M.D., Distinguished Professor of Pharmacology at the UCLA School of Medicine, will visit the Health Science Center April 12 and 13 as the Brackenridge Visiting Scholar. He will give both public and scientific talks. The George W. Brackenridge Foundation and the Health Science Center are the visit sponsors.
A distinguished pharmacologist from UCLA's Department of Molecular and Medical Pharmacology, Dr. Ignarro and two scientific colleagues jointly received the Nobel Prize in Physiology or Medicine for foundational discoveries about the role of the molecule nitric oxide. The other Nobel Laureates are Drs. Ferid Murad of The University of Texas Houston Health Science Center and Robert Furchgott of the State University of New York (SUNY) Health Sciences Center in Brooklyn.
The three were honored for discovering that nitric oxide acts as a signaling molecule in the cardiovascular system. The prize was the result of decades of work by the scientists, working independently much of the time and sometimes together.
Through a series of experiments and analyses, Dr. Ignarro concluded in 1986 that a signaling molecule called "endothelium-derived relaxing factor," identified earlier by Dr. Furchgott, was identical to nitric oxide.
When Drs. Ignarro and Furchgott presented their conclusions at a conference in July 1986, they set off a cascade of research activities around the world. It was the first discovery that a gas can act as a signaling molecule in an organism.
According to a 50-word citation on his work, Dr. Ignarro discovered that nitric oxide:
Holder of a Ph.D. in pharmacology from the University of Minnesota, the April 1999 Brackenridge Lecturer was a faculty member at the Tulane University School of Medicine in New Orleans from 1973 to 1985, when he joined the UCLA School of Medicine. He was a staff scientist for the CIBA-GEIGY Corp. from 1968 to 1972.
His many awards include the ROUSSEL UCLAF Prize for Cell Communication and Signaling, the CIBA Award for Hypertension Research and the Basic Research Prize of the American Heart Association.
Difficult to do, yes, but that is what scientists at the Health Science Center's Research Imaging Center (RIC) accomplished during PET studies of the brain and musical performance. PET, short for positron emission tomography, is a multimillion-dollar technology that enables scientists to pinpoint the brain's functions during various test activities.
A photo of the unusual music study, taken for an article published in the German magazine Stern, is so captivating that it recently captured an honor which, overseas, is the equivalent of the Pulitzer Prize for photojournalism.
The World Press Organization awarded first prize in its Single Scientific/Technology Photograph Category to Dr. Stephan Elleringmann's photo of pianist Sarabeth Pridgen.
"The Stern photographers and reporters first came to visit after hearing from researchers in Europe that we were doing interesting imaging work on music," said Dr. Lawrence Parsons, assistant professor at the Research Imaging Center. "They were so impressed that they came back two months later to do an article on all the center's studies. The published article inspired Panorama, an Italian magazine with half a million circulation, to produce its own article on the RIC."
Not to be outdone by the German and Italian press, a reporter from the French magazine VSD (translated "Friday, Saturday, Sunday" in French) subsequently visited the RIC. She wrote a story from the point of view of being a subject in the imaging center's various experiments, which included trans-cranial magnetic stimulation (TMS) studies of fine motor control, functional magnetic resonance imaging (fMRI) studies of sensory functions of the cerebellum, and electrical potential recording (ERP) studies of selective attention.
The RIC music performance study yielded provocative results. Eight right-handed professional pianists were brought to the Research Imaging Center, where they were scanned while playing scales, resting, and playing Bach's Italian Concerto. The third movement of the concerto was played from memory. "Perhaps our most surprising result was that during the Bach performance only, but not during the scales, many areas throughout the brain were deactivated," Dr. Parsons said.
"Many of these cortical regions are associated with the processes of self-consciousness, judgment, goal setting and rationalization, and their deactivation appears to be associated with a mental state of full conscious absorption in performance that musicians reported to be related to superior performance."
The study was the first view of whole brain function during purely music performance. A previous study, published in Science in 1992 by the late Justine Sergent, looked at musicians sight-reading a piece performed by the right hand only. Sergent also was a co-author on the RIC study.
RIC scientists noted increased activity in the brain's right temporal auditory cortex during the Bach concerto. This same activity was greatly reduced during the scales. "We were able to isolate brain functions processing the meaning and rules of music," Dr. Parsons said.
One of the sessions of the study was filmed for "Music and the Mind," a British Broadcasting Co. science documentary aired around the world.
A native of the Philippines, Dr. Grossman received her Bachelor of Science in Nursing from the University of Santo Tomas in Manila in 1977. Moving to the United States, she added her MSN in adult health nursing and nursing education at the University of Miami, Fla., in 1985. The capstone was her Ph.D. in nursing from the University of Pennsylvania in 1989.
Dr. Grossman moved here from Miami, where she was chair of the Department of Adult/Gerontological and Psychiatric Nursing at the Florida International University School of Nursing. She was with the University of Miami School of Nursing from 1985 to 1990, when she joined Florida International.
Her many honors and awards include the 1997 Excellence in Nursing Research Award presented by the Miami Veterans Affairs Medical Center and the 1996 Ada Sue Hinshaw Award, conferred by the Friends of the National Institute of Nursing Research. She was named 1996 Nurse Educator of the Year by the Florida Nurses Association. Dr. Grossman is an honored alumna of the University of Santo Tomas.
Courses taught by Dr. Grossman at Florida International University included Pharmacologic Basis for Nursing Practice; Adult/Gerontological Physiologic Nursing; Culture and Advanced Nursing Practice; Research Methods in Nursing; and Role Synthesis in Advanced Nursing Practice.
Cultural diversity in nursing is one of Dr. Grossman's emphasis areas. She authored a chapter on Cuban Americans in a 1997 text by Purnell and Paulanka, Trans-cultural Health Care: A Culturally Competent Approach. She is author or co-author of more than 50 scholarly articles and abstracts.
In demand as an invited speaker, Dr. Grossman has presented on many major nursing topics, including interventions for fever, biological rhythms of infancy and childhood, blood pressure rhythms, research in clinical practice, nursing education, the future of medical-surgical nursing, pathophysiology of sepsis and trans-cultural patient assessment.
"I am thrilled to be in a dynamic health science environment within a vibrant multicultural community," Dr. Grossman said of her new assignment.
Her husband, Dr. Joel Grossman, is a psychiatrist. They have two daughters, Regina, 10, and Claire, 9.

For diabetics, a tiny wound can turn into a huge one in no time because of poor blood circulation. Before the laser, keeping close tabs on such a wound proved to be challenging.
The laser measures wounds more accurately than other standard methods. "It's non-contact, and it takes no more than a few seconds to scan the wound with the laser," said co-inventor Leon Bunegin, associate professor, Department of Anesthesiology. "The laser not only is faster, but it provides a more reproducible measurement of the wound."
Nicholas Villarreal is one diabetic patient who has benefited from the Wound Imager. He is 47 years old and has been a participant in the experimental protocol of the laser measuring device. Recently, a small injury in his left foot turned into a massive one almost overnight. "I felt my leg getting bigger and the pain was excruciating," Villarreal said.
Prior to the laser, Villarreal had his wounds measured with a ruler or underwent "casting," which involves putting a gel-like substance into the wound, allowing physicians to get an idea of the depth of the wound. It is an uncomfortable procedure but is the only option to determine if treatments are healing the wound.
"With the laser imager, I can get accurate measurements of Mr. Villarreal's wounds daily and those measurements can help me determine if the current hyperbaric chamber treatment is working," said Dr. Adrianne Smith, assistant professor, Department of Surgery. "Also, when I see a rapid healing rate through the measurements, I can look into more conventional wound care techniques. The best news is it's not expensive nor does the patient experience any pain."
The idea for the laser imager of wounds has been around for a decade, but it took shape when Bunegin and co-inventor William Rogers, instructor of rehabilitation medicine, came together and figured out a way to apply the technology.
"The system is technically a structured lighting system," Rogers said. "The laser projects a plane of light and that light intersects a surface, the wound, producing a line. By viewing the line at an angle, we can determine the position of the line space, and by measuring the position of a number of lines, we can then reconstruct the shape of the wound."
The laser is not on the market, but Bunegin and Rogers expect it to be available in a few years.
The AFAR Board of Directors named Dr. Chatterjee to a three-year appointment on the Research Committee, which selects awardees for AFAR research grants. "The committee makes the final funding recommendations after initial evaluations by expert reviewers in respective fields," she said.
This May, Dr. Chatterjee will attend a meeting in New York for the 1999 selection of grantees. "This meeting is lively and gives insight into what is going on in the aging research community," she said.
Dr. George Martin, who spoke at the Aging Research & Education Center's first Age Day held in December, chaired the Research Committee in 1998. The other UT member, besides Dr. Chatterjee, is Dr. Jerry Shay of the UT Southwestern Medical Center at Dallas.
Deserving nominees can be found in every area, whether the job is typing grants on tight deadlines, conducting experiments in laboratories, grooming huge areas of landscaping, or buffing and waxing floors. Anyone who improves service in his or her area, or who saves time, money or materials, is worthy of consideration.
The revised 1999 nomination package is available in the Office of Human Resources. Questions may be directed to the Office of Employee Development & Training, ext. 2323.
Five winners will be recognized at the annual Service Awards Ceremony in the fall.
The 1999 series will explore the theme of "The Beginning and End of Life," covering the wonders and complexities of human development on the one hand, and the aging process on the other. The three weekly sessions will last from 7 to 9 p.m. Tuesdays in lecture hall 3.102B.
The lecture series is a free-of-charge gift to the South Texas community for its generous support of the Health Science Center--support that furthers the university's missions of teaching, research, patient care and service. A science background is not required and persons of all ages are welcome.
Registration is required because of limited seating capacity, and enrollment is on a first-come basis. To register or for a copy of the registration form, call ext. 1925 or send e-mail to <ramonj@uthscsa.edu>.
The program provides informative and interesting presentations from the different points of view that are unique to the Health Science Center: basic research, medicine, nursing, dentistry and the allied health professions.
The March 30 session will explore "The Beginning of Life and Its Challenges," including presentations on human embryology, birth defects and surgical repair of congenital hand defects. On April 6, speakers will shed light on "How the Body Changes at the End of Life." Topics will include cell death, rheumatoid arthritis and disease prevention in the elderly.
Mini-Medical School students present for the closing April 13 session will be treated to a talk by 1998 Nobel Laureate Dr. Louis Ignarro. He will relate how the Nobel Prize-winning discoveries in medicine will influence health and disease in the new millennium.
