Journal ArticleDOI
Norepinephrine controls astroglial responsiveness to local circuit activity
TL;DR: It is demonstrated that norepinephrine primes astrocytes to detect changes in cortical network activity and shifts the gain ofAstrocyte networks according to behavioral state, enabling them to respond to local changes in neuronal activity.
Journal ArticleDOI
Functional stimuli responsive hydrogel devices by self-folding
TL;DR: A photolithographic approach to create functional stimuli responsive, self-folding, microscale hydrogel devices using thin, gradient cross-linked hinges and thick, fully cross- linked panels with reversible stimuli responsive properties just below physiological temperatures is described.
Journal ArticleDOI
Real-time three-dimensional Fourier-domain optical coherence tomography video image guided microsurgeries
Jin U. Kang,Yong Huang,Kang Zhang,Zuhaib Ibrahim,Jaepyeong Cha,W. P. Andrew Lee,Gerald Brandacher,Peter L. Gehlbach +7 more
TL;DR: An ultrafast three-dimensional (3D) optical coherence tomography (OCT) imaging system that provides real-time intraoperative video images of the surgical site to assist surgeons during microsurgical procedures is described.
Journal ArticleDOI
Deep Neural Network Regression for Automated Retinal Layer Segmentation in Optical Coherence Tomography Images
Lua Ngo,Jaepyeong Cha,Jiyeon Han +2 more
TL;DR: An automated segmentation method for OCT images based on a feature-learning regression network without human bias is proposed, which operates robustly on OCT images containing intensity variances, low-contrast regions, speckle noise, and blood vessels, yet remains accurate and time-efficient.
Journal ArticleDOI
A chemically stable fluorescent marker of the ureter.
Jaepyeong Cha,Roger R. Nani,Michael Luciano,Gabriel Kline,Aline Broch,Ki-Hoon Kim,Jung-Man Namgoong,Rhushikesh A. Kulkarni,Jordan L. Meier,Peter C.W. Kim,Martin J. Schnermann +10 more
TL;DR: The design and synthesis of a water soluble, net neutral C4'-O-alkyl heptamethine cyanine, Ureter-Label (UL)-766, with excellent properties for ureter visualization is reported, which represents a promising candidate for visualizing the ureters during a variety of surgical interventions.
