Jim Pawelczyk, associate professor of physiology, kinesiology and medicine at Penn State, testified before the Subcommittee on Space in the U.S. House of Representative’s Committee on Science, Space and Technology on Friday, July 10 in Washington, D.C.
Athletes who down beet juice before exercising to increase blood flow and improve performance may be surprised at the results of a recent study conducted at Penn State's Noll Laboratory. While beetroot juice rich in nitrates did not enhance muscle blood flow or vascular dilation during exercise, researchers found that it did "de-stiffen" blood vessels under resting conditions, potentially easing the workload of the heart.
Mary Jane De Souza, professor of kinesiology and physiology, presented “Understanding the Clinical Sequelae of the Female Athlete Triad,” as part of a Chinese delegation. About 25 sport physicians, physical therapists and sport scientists visited University Park from Oct. 20-24 to learn the latest in sport medicine clinical practices, scientific research, and training and conditioning.
The Penn State Alumni Association will hold a City Lights event March 26 at NASA's Johnson Space Center in Houston. The event, from 9 a.m. to 4 p.m., will allow Jim Pawelczyk, astronaut and associate professor of physiology and kinesiology, to lead a tour of the Spacelab training module -- an exact replica of the one in which he traveled to space -- before his program, titled "To infinity and beyond: Defining the human limits of space exploration." His presentation will discuss some of the technical and scientific hurdles that need to be overcome in order to allow human planetary exploration.
A mechanism that regulates stem-cell differentiation in mice testes suggests a similar process that may trigger degenerative disease in humans, according to a Penn State College of Agricultural Sciences reproductive physiologist. Research involved manipulating a protein called STAT3, which is active in tissues throughout the body and is essential for life, that signals stem cells to decide whether to differentiate into a specialized type of cell or self-renew and remain stem cells.
Stephanie Eldred, a kinesiology student, is the recipient of a 2010 Undergraduate Research Fellowship through the American Physiological Society. She is one of only 24 students across the country to receive this honor, and she will be working under the supervision of Donna Korzick, associate professor of physiology and kinesiology, studying the link between estrogen levels and heart disease in older women.
A new study on old rats by a Penn State researcher will shed light on the connection between estrogen deficiency, heart disease and aging in women. Heart disease is the leading cause of death in women over the age of 75. After menopause, women lose their ability to produce the hormone estrogen and researchers believe that low estrogen levels somehow make women more vulnerable to heart disease and heart attack.
Howard E. Morgan, 81, founding chair of Penn State College of Medicine's Department of Physiology, died Monday, March 2, at the age of 81. Morgan was internationally regarded as one of the greatest experimental cardiologists of the 20th century. His strong commitment to excellence in heart research came from a clear vision of blending basic sciences with clinical cardiology, and he was deeply devoted to helping cardiovascular scientists reach their potential.
After finishing a long run in the heat of a July afternoon, you're thirsty, your muscles are weak, you feel generally fatigued, and you may have a minor headache. Your body is telling you that it needs to be rehydrated, so you grab a bottle of water from the refrigerator. It's cold and refreshing, but how well is that H2O replenishing the nutrients you lost during your workout? According to W.
You're flying through the air, the wind in your face. Or you're being chased by a team of menacing bad guys. Or perhaps you're chatting with a long-dead family member.
Though these adventures can feel incredibly real, they are, in fact, the stuff of dreams. Dream scenarios range from the calm and mundane to the surreal and dramatic—and certain themes, such as falling or being chased, seem to be universal.
President Bush's recent proposal to focus NASA's efforts on manned space exploration has rekindled efforts to define the human limits on long voyages in deep space. According to Jim Pawelczyk, an associate professor of kinesiology at Penn State and a payload specialist on the 1998 Columbia mission, there are three major "showstoppers" that need to be addressed.
