At TEDx Baltimore guest speaker Warren Grayson, associate professor in biomedical engineering at Johns Hopkins, discusses a revolutionary new approach for tissue engineered facial bone reconstruction. Dr. Grayson describes a process where patient-specific anatomically-correct 3-D printed bone is created. This 3-D base, called the scaffold, is enhanced with the patient’s own living tissue. The living tissue grows as the scaffold biodegrades. The resulting tissue-regenerated structure becomes a living component — so that as the patient grows and changes the regenerated bone grows and changes along with patient.

BME PhD student researchers Xindong Song and Yueqi Guo uncover evidence that pitch perception evolved in primate
The ability to perceive the sound quality known as “pitch” can no longer be listed as unique to humans. Research published online in the journal Proceedings of the National Academy of Sciences, entitled “Complex pitch perception mechanisms are shared by humans and a New World monkey,” infers that aspects of pitch perception may have evolved more than 40 million years — enabling the songlike vocalization by the marmoset monkey. The paper appeared on the cover of PNAS, Issue No. 3, January 19, 2016.
The Johns Hopkins research authors include BME graduate students Xindong Song (lead author) and Yueqi Guo, BME Research Associate Michael Osmanski, and Professor of Biomedical Engineering, Xiaoqin Wang.
Building on Dr. Wang’s previous research previous research that revealed regions in the marmoset brain responded to pitch in a way similar to that the human brain, the research team focused on finding behavioral evidence of pitch perception. Through a series of hearing tests, with waterspout licks as a readout, Wang’s team, led by graduate student Xindong Song, determined that marmosets share the three specialized features of pitch perception once thought to be unique to humans.

The ability to perceive the sound quality known as “pitch” can no longer be listed as unique to humans. Johns Hopkins researchers — including auditory neuroscientist and Professor of Biomedical Engineering, Xiaoqin Wang — report new behavioral evidence that marmoset monkeys, with a hearing range similar to that of humans, appear to use auditory cues similar to humans to distinguish between low and high notes.
The discovery infers that aspects of pitch perception may have evolved more than 40 million years ago to enable vocal communication and songlike vocalizations.
The research paper, Complex pitch perception mechanisms are shared by humans and a New World monkey, was published online in the journal Proceedings of the National Academy of Sciences. Learn more ►

BME faculty publish research findings to aid in determining effective biological therapies for improved cardiac function
In a scientific paper published online in Nature, researchers — including BME Assistant Research Professor Patrick M. Boyle and Murray B. Sachs Professor Natalia Trayanova — share research findings that use optogenetic tools to help identify effective biological therapies for improved cardiac function (as opposed to use of implants such as pacemakers). The investigators used optogenetics to selectively target cardiac cells for excitation through viral gene therapy.
The research paper, Optogenetics-enabled assessment of viral gene and cell therapy for restoration of cardiac excitability, is the results of an intensely collaborative project between research teams at Johns Hopkins and Stony Brook Universities. The Johns Hopkins research group led the charge on simulations, while Prof. Emilia Entcheva’s group at Stony Brook University conducted in vitro experiments. The investigative teams tested the optical energy needed to sufficiently excite the deficient cardiac cells and then computationally predicted therapeutic efficiency of the targeted cells with gene therapy restoration methods.
The study results can help guide optogenetic interventions for light-based control of cardiac excitation and can help optimize gene therapy for restoration of cardiac excitability.

A team of eight Johns Hopkins undergraduate biomedical engineering students were awarded first place and a prize of $25,000 by judges of the 2015 Retail and Health Innovation Challenge held at Wake Forest University School of Business in Winston-Salem, NC.
The BME entrepreneurs — Haley Huang, Tom Catullo, Barbara Kim, Stephen Johannesson, Esteban Urias, Eric Chiang, Anshul Subramanya, and Tony Sun — have created a simple, innovative solution for the problem of puncturing the spinal cord during revision spinal surgery. This specialized surgical device, Separatec, was designed to minimize the risk of leaking spinal fluid in the thin membrane surrounding nerves in the spinal column, especially when scar tissue from previous surgeries is present.
The Separatec surgical instrument tip incorporates key design features that make use of the tool safer for the patient, easy for surgeons to use, and more effective than the current standard of care. It is expected that use of Separatec will decrease the occurrence of cerebrospinal fluid leaks, expedite patient recovery, and decrease surgical expense.
Congratulations to the team and best of luck in their business venture: BHEST Medical LLC. Read the full article.
