Madison Sturgeon and Austin Murphy Receive ICRU Fellowships!

Seniors Austin Murphy and Madison Sturgeon have been chosen as Iowa Center for Undergraduate Research (ICRU) fellows for the 2016-2017 school year! The ICRU fellowship provides $2000 to students that are engaged in undergraduate research.  More information about the program can be found here.

Austin and Madison have each been members of the lab for a year and are working toward completing their senior honors thesis work. The both are investigating the long-term impact of prematurity.  We’re lucky to have them in the lab and congratulate them on this awesome success!

Dr. Bates Recognized for 10 Years of Membership by the American Physiological Society

FullSizeRenderThis month marks Dr. Bates’s tenth year of membership in the American Physiological Society (APS). Since joining the society as a 3rd year graduate student in 2006, Dr. Bates has had the pleasure of serving on the Respiration Section Steering Committee, the Trainee Advisory Committee, the Strategic Planning Committee and the Communications Committee, and as a contributor to the David Bruce Award and Respiration Section Trainee Endowment. Popular science writing contributed by her and her students can be found on the APS blog I Spy Physiology.

The APS is a non-profit organized who mission is to foster education, scientific research, and the dissemination of information in the physiological sciences. The Society was founded in 1887 with 28 members. APS now has over 10,500 members. Most members have doctoral degrees in physiology and/or medicine (or other health professions). Members of the society often attend the annual Experimental Biology meeting where Dr. Bates’s graduate and undergraduate frequently present the lab’s work. Several of Dr. Bates’s former students have been recipients of the David Bruce Award for Excellence in Undergraduate Research. Membership in the APS offers an outstanding opportunity to learn about the most ground-breaking science and interact with leaders in physiology. Dr. Bates is especially grateful for the opportunities the society has provided and looks forward to another 10 years of membership!

Tyler Greiner Gives Platform and Poster Presentation at EB2016

Post-baccalaureate student and Health and Human Physiology graduate Tyler Greiner presented his study titled “Pulmonary and Systemic Vascular Responses in Rats Exposed to Perinatal Hyperoxia” at the 2016 Experimental Biology in San Diego. Tyler was invited to present a poster and give a talked during the feature topics session on Origins of Adult Cardiovascular and Metabolic Disease.

He also got a chance to check out some other awesome presentations.

Tyler and Nitin

This achievement reflects Tyler’s year of hard work in the laboratory. He’ll be leaving to attend medical school in the summer. You can read more about Tyler’s study at Pascale Lane’s blog WhizBang.

Paper on Chronic Intermittent Hypoxia and Ventilation Published in the Journal of Applied Physiology

Complications of Sleep Apnea

Our paper with collaborators Barb Morgan, Russ Adrian, Zun-yi Wang and John Dopp titled “Chronic intermittent hypoxia alters ventilatory and metabolic responses to acute hypoxia in rats” was accepted in the Journal of Applied Physiology this week.

Patients with sleep apnea experience periods during sleep where breathing stops. This can occur as many as 60 times per hour. These apneas, which cause periodic, intermittent falls in blood oxygen (hypoxia), can contribute to hypertension, obesity, cancer, and other diseases. It is also unknown  whether having these apneas alters the neural circuitry that controls ventilation and promotes more apneas.  Our study addresses the controversy of whether chronic exposure to intermittent hypoxia enhances ventilatory chemosensitivity. We quantified hypoxic chemosensitivity in conscious rats using a novel method which—unlike most previously published approaches—was able to uncover key effects of prolonged intermittent hypoxia on both metabolic and ventilatory responses to acute hypoxia. We found that hypoxic chemosensitivity is indeed enhanced by intermittent hypoxia and thus is a potentially important contributor to sleep disordered breathing in humans.
