How estrogen's millisecond-fast action happens
Oct. 2, 2024
Estrogen, the major female ovarian hormone, can trigger nerve impulses within milliseconds to regulate a variety of physiological processes. At Baylor College of Medicine, Louisiana State University and collaborating institutions, researchers discovered that estrogen’s fast actions are mediated by the coupling of the estrogen receptor-alpha (ER-alpha) with an ion channel protein called Clic1.

Eating for necessity or pleasure? There is a brain circuit for that
Aug. 8, 2024:
People eat either because they are hungry or for pleasure, even in the absence of hunger. While hunger-driven eating is fundamental for survival, pleasure-driven feeding may accelerate the onset of obesity and associated metabolic disorders.

After dedicating 21 years of leadership to the Children's Nutrition Research Center (CNRC), Perry Rainosek is embarking on a new chapter within the USDA, Agricultural Research Service (ARS). Recently Perry held several temporary assignments with the USDA, while simultaneously continuing to support the CNRC. Perry has now embraced a permanent role as the USDA, ARS Deputy Chief of Staff. While the agency is based in Washington, DC/Beltsville, MD, Perry will continue to work remotely from the Houston area. Throughout his tenure at the CNRC, Perry ensured seamless federal operations. The CNRC faculty and staff owe him a tremendous debt of gratitude for his unwavering dedication. We extend our heartfelt wishes for success in his new role.
A Symposium held on Jan. 22, 2024, at the Children’s Nutrition Research Center (CNRC) celebrated the remarkable scientific career and leadership of Dr. Dennis M. Bier, a distinguished figure in pediatric endocrinology and nutrition research. Dr. Bier's journey began with his graduation from Le Moyne College and the University of Medicine and Dentistry of New Jersey, followed by fellowships at the University of California, San Francisco (UCSF) and service in the U.S. Naval Reserves. Returning to Washington University School of Medicine (WUSM), he co-directed the Division of Pediatric Endocrinology, pioneering research in mass spectrometry to explore nutrient kinetics and metabolic pathways.
Beyond the laboratory, Dr. Bier's influence extends to leadership roles at the National Institutes of Health (NIH) and directorships at WUSM and the CNRC at Baylor College of Medicine (1993-today). His commitment to mentorship and scientific rigor has propelled advancements in pediatric nutrition research. The afternoon symposium served as both a homage to his career and a critical examination of the strengths and weaknesses within the field of nutrition. Opening remarks were given by Dr. Morey Haymond and presentations by prominent researchers: Dr. David Allison, Dr. Elmquist, Dr. Christopher Newgard, and Dr. David Klurfeld. The event concluded with closing remarks from Dr. Teresa Davis, followed by a reception attended by colleagues from across the nation, honoring Dr. Bier's extraordinary career.
Alvin Tak, a University of Houston student currently engaged in research within Michael Dzakovich's lab has been selected as an IRTA (Intramural Research Training Award) scholar. Alvin will dedicate the upcoming year to conducting studies in Dr. John Ngai's laboratory, with a specific focus on olfactory nerve regeneration. With ambitions of becoming a clinician-scientist, Alvin is determined to pursue a dual M.D./Ph.D. program in neuroscience. (February 2024)
