Yue lab calcium signaling study published in Nature

BME faculty member David Yue and colleagues Xiaodong Liu, Phil Yang, and Wanjun Yang, all of the Calcium Signals Laboratory, have published a study in the international journal Nature (Advanced Online Publication 2/7/2010, http://www.nature.com/nature/journal/v463/n7283/abs/nature08766.html). The authors simultaneously combined patch-clamp electrophysiology to characterize calcium ion channel function with genetically-encoded optical sensors to measure cell signaling factors, […]

Heart cells display ‘nano sense’ on new lab chip

Johns Hopkins Department of Biomedical Engineering faculty Andre Levchenko and Les Tung along with colleagues in Korea have found that heart cell and tissue properties can be controlled by varying the nano-scale topography of the scaffolds supporting the cells, a surprising indication that heart cells possess a ‘nano-sense’ capable of responding to minute differences in […]

Growing bone in exact shapes

Picture series showing the bone matrix as it develops. BME faculty member Warren Grayson, along with colleagues Gordana Vunjak-Novakovic and others, have grown bone grafts in the exact shape of a desired bone, an advance that could help provide doctors with just what they need for face, skull and other skeletal reconstructions. Using real bone […]

Karchin computer program IDs likely cancer mutations

Johns Hopkins assistant professor of biomedical engineering Rachel Karchin and doctoral student Hannah Carter led a Johns Hopkins team that developed innovative computer software that can sift through hundreds of genetic mutations and highlight the DNA changes that are most likely to promote cancer. The goal is to provide critical help to researchers who are […]

Chemical found in medical devices impairs heart function

A BME researcher’s personal experience after cardiac surgery motivated a search for the cause of some common side effects of heart surgery. Artin Shoukas, Ph.D. (left), professor of biomedical engineering, physiology and anesthesiology and critical care medicine, found that after his coronary bypass operation, his sense of taste was negatively altered. Loss of taste and […]
