Congratulations Dr. Carroll Cross, recipient of the Internal Medicine Career Achievement Award!
Dr. Cross literally founded our division of Pulmonary/Critical Care Medicine in 1968 when he served as our chief. He likes to describe how he was one of the first “ten or twenty” faculty, not of the division or department, but of the School of Medicine. Over time, he has built an international reputation in research and education and clinical care and he remains extraordinarily active in local and national societies, much to the amazement of the other pulmonary faculty. As he has done throughout his career, Dr. Cross continues to read the literature fully and furiously. Nobody has ever seen anyone consume and grasp as many research papers as Carroll. Each week, pulmonary faculty gets a series of papers and abstracts to review in their mailbox. These papers are always in the investigators’ field and are usually seen first by Carroll. It is his way of taking care of the junior and mid-career faculty. It is truly awe-inspiring to witness this capacity to read and share the literature after forty plus years as a faculty member. How he maintains this practice certainly deserves further explanation if he wins this award!
Dr. Cross’ career long expertise has been in the fields of cystic fibrosis (CF), alpha-1 antitrypsin (A1AT) deficiency, and the generation and function of reactive oxygen species in the lung. He remains the director of the A1AT program and co-director of the CF program in our division. I have no idea what the exact publication count is for Dr. Cross but it is approaching 300 publications. A review of PubMed for his earliest manuscripts revealed three publications each in Circ Res and Am J Physiol in 1960! Many of his publications are cited over 50 times. In the past 20 years, I would highlight his papers in JBC, AJRCCM, Free Rad Biol Med, AJP, AJM all describing the function of myeloperoxidase and reactive oxygen and nitrogen species as being particularly impactful. He has been NIH funded for decades with an R21 recently completing in 2013. Perhaps most important to our division, Dr. Cross wrote our original T32 Comparative Lung Biology Training Grant and served as PI and Co-PI for over 30 years (Grant # 7033 from NHLBI!). This grant has trained numerous faculties in the medical school and veterinary school at UC Davis and beyond. This alone would be a career-worthy accomplishment.
In summary, he is an outstanding mentor to many faculty in the division even after year 40 as faculty. He has been our translational research leader for decades, long before the term was defined.

Congratulations Dr. Valentina Medici, recipient of the 2015 Internal Medicine Faculty Research Award!
After her graduation summa cum laude with the MD degree from the prestigious University of Padova in 2000 and subsequent fellowship training in Gastroenterology and Hepatology in Germany, Dr. Medici returned to the University of Padova where she began her research on the pathogenesis and management of Wilson disease (WD). This resulted in 8 publications of which she was first author on 5, that were clinical except for 3 that involved rat models of hepatic copper overload. Subsequently she moved to our institution in 2006 to become a visiting Assistant Professor and K30 scholar in our Mentored Clinical Scientist Development Award. Her subsequent research has focused on two areas of alcoholic liver disease (ALD) and WD.
Alcoholic liver disease: As a K30 scholar, she obtained her clinical research training under my direction in an NIH funded study of S-adenosylmethionine (SAM) in the treatment of ALD. In addition to the rigorous double blind clinical study (14 in her Biosketch), she made an original observation that the transsulfuration pathway of methionine metabolism was specifically compromised in ALD (1). A subsequent study in a mouse model of ALD confirmed the ethanol induction of changes in liver methionine metabolism with resultant reduction of the primary methyl donor SAM and reduced gene-specific DNA methylation with increased gene expression of inducible nitric oxide synthetase (iNOS), a known pathway for liver injury (4). Summarizing, these translational studies have confirmed and provided a mechanism for ethanol induced altered hepatic methionine metabolism in the pathogenesis of alcoholic liver injury and disease.
Wilson disease: While identifying altered hepatic methionine metabolism in ALD, she made the highly original connection that similar mechanisms could be operative in the pathogenesis of WD, a rare congenital disease of copper overload of the liver and the topic of all her prior research in Italy. This hypothesis and subsequent research led to successful acquisition of a prestigious NIH K08 new faculty development and later R03 awards. Her studies first demonstrated the association of hepatic copper overload with enhanced levels of S-adenosylhomocysteine (SAH), a primary inhibitor of gene methylation, whereas copper reduction or provision of the alternate methyl donor betaine restored global DNA methylation while increasing SAM and reducing a gene pathway for liver necrosis and inflammation (2). A subsequent mechanistic study showed parallel changes over time from fetal life to adulthood of copper accumulation, reduced SAH hydrolase transcripts, enhanced SAH levels with reduced DNA methylation (5). A third study demonstrated the epigenetic generational transmission of WD by finding that maternal provision of the methyl donor choline could prevent many of the transcriptional defects in WD fetal and 28 d old livers while enhancing global DNA methylation in the same mouse model (3). These studies form the basis of a current NIH R01 application which will further explore epigenetic effects of methyl donors in potential prevention and treatment of WD.

Congratulations Dr. Tonya Fancher
Congratulations Dr. Tonya Fancher! Dr. Fancher is the recipient of the 2014-2015 Chancellor's Achievement Award for Diversity and Community.
Congratulations Dr. Sanket Dhruva!
Sanket Dhruva, M.D. (PGY-6, cardiology) was recently accepted to become a Robert Wood Johnson Clinical Scholar at Yale University from 2015-2017. During medical school and internal medicine residency training at UCSF, he studied FDA regulation and Medicare coverage of medical devices. His work has been published in the New England Journal of Medicine, JAMA, and the British Medical Journal. During his cardiology fellowship at UC Davis, he has gained a better understanding of how devices are used to better the health of patients with cardiovascular disease and hopes to use the two-year clinical scholars program as a transition to an academic career.
Congratulations to the Division of Cardiovascular Medicine!
