Bethesda, MD - The long term objective of the 2015 Conference is to advance collaborative interactions between investigators that study different basic aspects of mitochondrial biology and translational investigators engaged in studying mitochondrial roles in human health, disease, and aging. These collaborative interactions are essential to develop innovative interdisciplinary approaches to further our understanding of mitochondria at the fundamental, translational and clinical levels. To achieve our long term objective, our immediate objectives are: To cover 8 major topics: 2) Mitochondrial protein quality control 3) Heme, Fe-S clusters and metal cofactors in mitochondrial metabolism 4) Mitochondrial stress in cell signaling and aging 5) Mitochondrial dynamics in development and disease 6) Nuclear DNA-driven mechanisms of mitochondrial disease 7) New Pathways, Biomarkers and Technologies to Study Mitochondrial Function 8) Challenges and Opportunities in Mitochondrial Biology and Medicine.

Bethesda, MD - The 2015 FASEB Science Research Conference Melatonin Biology: Actions and Therapeutics will focus on the role of melatonin and its analogues as potential drugs in the treatment of sleep and circadian disorders, insomnia, cancer, immune dysfunction, inflammatory processes, and neurodegenerative disease. The information presented will range from the continuing identification of a new role for melatonin in supporting health to the understanding of melatonin receptors in the diagnosis and prevention of human disease. This fourth international conference is the only one of its kind to bring together investigators from around the world with an interest in studying melatonin and its biology for the purpose of developing novel therapeutic agents. FASEB has announced a total of 34 Science Research Conferences (SRC) in 2015. Registration opens January 20, 2015. For more information about an SRC, view preliminary programs, or find a listing of all our 2015 SRCs, please visit http://www.faseb.org/SRC. ### Since 1982, FASEB SRC has offered a continuing series of inter-disciplinary exchanges that are recognized as a valuable complement to the highly successful society meetings. Divided into small groups, scientists from around the world meet intimately and without distractions to explore new approaches to those research areas undergoing … Continue reading →

Scientists at the University of Saskatchewan College of Medicine, Department of Physiology, Saskatoon, Canada, led by Dr. Joseph Fomusi Ndisang have determined that upregulating heme-oxygenase with hemin improves pericardial adipocyte morphology and function. It does so by enhancing the expression of proteins of repair and regeneration such as beta-catenin, Oct3/4, Pax2 as well as the stem/progenitor-cell marker cKit, while concomitantly abating inflammatory/oxidative insults and suppressing extracellular-matrix/profibrotic and remodeling proteins. Visceral adiposity like pericardial fat is correlated to insulin resistance and cardiac disease, and this is amongst the major causes of cardiac complications in obese individuals. By virtue of its anatomical and functional proximity to the coronary circulation, pericardial adiposity can lead to myocardial inflammation, left ventricular hypertrophy and coronary artery disease through paracrine mechanisms that include increased production of inflammatory cytokines, reactive oxygen species and other atherogenic factors. These findings, which appear in the January 2015 issue of Experimental Biology and Medicine, used a laboratory animal model characterized by obesity, hypertriglyceridemia, hypercholesteromia, insulin resistance, dyslipidemia and excessive pericardial adiposity, all of which are major pathophysiological causes of heart failure and related cardiac complications in patients with obesity. Dr. Ndisang and co-worker underscored the protective role of heme-oxygenase in obesity and … Continue reading →

The award committee granted the award with "great enthusiasm," noting that, "Plotkin's research achievements belie his young age." The prize is given every other year, alternately to a senior scientist for lifetime achievement, and, as is the case this year, to a junior scientist younger than 40. The award honors scientists "for outstanding and innovative theoretical work, for establishing superb conceptual ideas, for solving tough theoretical problems and/or for uniting theory and data to advance biological science." Plotkin was judged to "amply satisfy" these criteria. Plotkin is a professor with joint appointments in the Department of Biology in Penn Arts & Sciences and in the Department of Computer and Information Science in the School of Engineering and Applied Science. His research employs mathematics to address biological questions on topics as varied … Continue reading →

The Big History Project, an international education initiative funded by Bill Gates that intends to provide a comprehensive history of the universe and humanity in a cohesive curriculum, features several notable scientists and historians, including Washington University professor of biology Ursula Goodenough. Professor Ursula Goodenough, a member of the Biology department, sits in her office. She has recently contributed to the Big History Project, a free, online-based initiative funded by Bill Gates. The free, online-based course begins with coverage of the Big Bang and continues up through modern history and the present. As of fall 2014, over 1,200 primary and secondary schools and 15,000 students have begun to use the Big History Project for their curriculum. The Big History Project reflects the increasing trend of free online education, joining organizations such as Khan Academy and universities like the Massachusetts Institute of Technology that offer public courses. Goodenough has published several papers and two books on the subjects of cell biology and religious naturalism. She believes that the Big History Projects interdisciplinary initiative can improve secondary education across the country as a whole. It certainly seems to me that the understanding of the history of the universe and the planet and … Continue reading →
