alcohol tolerance, Alcohol Consumption, genetics and addiction, Neurobiology

Professor, Department of Pharmacology, University of Colorado School of Medicine, Aurora, CO.

Research has focused on neural mechanisms of adaptation to alcohol, including tolerance and dependence.  Identified a  role of peptide hormones and brain growth factors to modify alcohol tolerance.  

Discovered that one subtype of glutamate receptor, the NMDA receptor, is very sensitive to alcohol, and that increases in NMDA receptor function are involved in alcohol dependence.  This work has led to many further studies by others that focus on the role of the brain  glutamate systems in addiction to alcohol and other drugs.  

Currently focus on systems genetic analysis, using "big data" to understand the genetic contribution to alcohol-related and other complex behaviors.

vaping, e-cigarettes, Smoking, Lung Disease

In the Lone Star State, the Texas Health Department has confirmed that a teen got lung disease after vaping. Pushan Jani, MD, assistant professor of pulmonary and sleep medicine at McGovern Medical School at UTHealth in Houston, has been keeping up with the rise of tobacco substitutes such as e-cigarettes and is available to comment on this development. E-cigarettes produce an aerosol by heating a liquid that usually contains nicotine—the addictive drug in regular cigarettes, cigars, and other tobacco products—flavorings, and other chemicals that help to make the aerosol, according to the Centers for Disease Control and Prevention. Users inhale this aerosol into their lungs. Bystanders can also breathe in this aerosol when the user exhales into the air. Jani, who is also affiliated with Memorial Hermann-Texas Medical Center and UT Physicians, has several issues with the tobacco substitutes. According to published research data, the flavoring agents used in vaping products can cause inflammation and damage to the lungs. While there is no tobacco, users are still getting nicotine. The impact of vaping to bystanders is not known. In practice since 2007, Jani is a full-time interventional pulmonologist and bedside educator. Jani’s clinical expertise is in procedural care, including electromagnetic navigational bronchoscopy, endobronchial ultrasound-guided biopsies (EBUS), transtracheal oxygen catheter insertions, and percutaneous dilatational tracheostomy.

Julián Jefferies is assistant professor in the Department of Literacy and Reading Education at California State University, Fullerton. He is interested in the daily lives of immigrant youth in schools and their representation in the media. Focusing on the experiences of undocumented youth, his research uncovers how society as a whole and schools in particular deal with the migration status of their students and how meritocratic ideologies work to justify the opportunity gaps for Latina/o youth in education. He has published on the framing of immigrant youth in public opinion and is currently working on research that alerts educators in K-12 institutions and policymakers on how to best serve undocumented youth in their schools. He is also interested in the pedagogy of international and experiential learning opportunities and coordinates a summer program in Puerto Rico and the Virgin Islands, where he investigates how students gain cross-cultural competence and re-think their national, gender, ethnic and cultural identities.

He currently has over 150 scientific publications and has lectured widely on the clinical and molecular aspects of breast cancer pathology. Dr. Jensen's research interests are focused on understanding the function of BRCA1 and BRCA2 and their role in breast and ovarian neoplasia; and in the characterization of premalignant breast disease both at the morphologic and molecular levels. His laboratory was instrumental in demonstrating the role of BRCA1 in the growth control of normal and malignant cells and in how loss of functional BRCA1 contributes to the development of breast cancer.

Since becoming director of The University of Kansas Cancer Center in 2004, he has recruited a world-class leadership team and successfully led that team in achieving designation for The University of Kansas Cancer Center as a National Cancer Institute designated cancer center.
