Aging expert to deliver UI exercise science department
Alley Memorial Lecture
IOWA CITY, Iowa -- An expert in the physiology of aging
will present the seventh annual Louis E. Alley Memorial Lecture in the University
of Iowa department of exercise science at 3:30 p.m. April 22. Raj Sohal, a
professor of biological sciences at Southern Methodist University, will present
his lecture, "The Role of Oxidative Stress in Aging," in the Medical Alumni
Auditorium, E331 General Hospital.
Oxidative stress is the damage caused to cells due to
oxidants. Sohal is a leading authority in the field of oxidative stress and
aging and is studying the ways in which an oxidant imbalance contributes to
the physical decline associated with aging. His hypothesis is that animals
produce more oxidants as they age, leading to increased cell damage and ultimately
Further study is needed in this area, but Sohal's research
may ultimately enhance the quality of life for the aging population by finding
a way to maintain proper balance between oxidants and antioxidants in the
The UI department of exercise science holds this memorial
lecture each year in honor of Louis E. Alley, a longtime professor of physical
education at the UI who died suddenly in 1991. Alley was head of the department
of physical education for men for 18 years, beginning in 1960. During that
time he initiated and supervised a major revision of the graduate program
in physical education. He introduced to graduate physical education the notion
of areas of specialization and sought faculty members capable of providing
in-depth instruction in these specialist areas.
Alley's influence was also felt at the national level
through his service as leader of every major professional group in his field.
