Study on the deformation of endothelial cells using a bio-inspired in ...

Post Image Based on the observation that abnormal endothelial cells(blue arrows) and denatured collagen fibers(red arrows) in blood vessels of a normal zebrafish fed with high cholesterol diet were indicated, a bio-inspired in vitro model was established to...   내용 보기

Biophysiochemical properties of endothelial cells cultured on bio-insp...

Post Image Endothelial cells cultured on the denatured-collagen films have different biophysiochemical properties compared to those cultured on the normal films. Specifically, surface of HUVECs on the denatured-collagen films was highly disorganized with th...   내용 보기

Whole-Body Imaging of a Hypercholesterolemic Female Zebrafish by Using...

Post Image Visualizing whole-volume of the zebrafish tissues is limited by pigmentation and hard tissues. The 3D microstructures of a high-cholesterol zebrafish are visualized by synchrotron X-ray micro-computed tomography(SR-μCT). Various microstructure or...   내용 보기

Microfluidic method for diagnosis of malaria-infected blood

Post Image For an effective ESR measurement, a disposable syringe filled with blood is turned upside down and aligned at 180° with respect to gravitational direction. The variation of hematocrit is evaluated by consecutively capturing images and conducting d...   내용 보기

Effect of malaria infection in spleen

Post Image Malaria infection affects to the erythrocytes viscosity. We treated antioxidants in malaria-infected in vivo and in vitro models. Antioxidants show the protective effects on malaria-induced oxidative stress in erythrocytes and organs. They inhibit...   내용 보기

Beneficial fluid-dynamic features of swirling flow in end-to-side anas...

Post Image Pathological fluid-dynamic characteristic sin a 45° end-to-side anastomosis were experimentally investigated using a particle image velocimetry technique. The fluid dynamic features of the pulsatile swirling flow are expected to be beneficial in d...   내용 보기

Fluid-dynamic optimal design of helical vascular graft for stenotic di...

Post Image The swirling flow in a helical graft was hypothesized to have beneficial influences on a disturbed flow structure such as stenotic flow. The characteristics of swirling flows generated by helical tubes with various helical pitches and curvatures ...   내용 보기

Measurement of pulsatile blood flow using X-ray PIV

Post Image In this study, the proposed X-ray PIV technique was used to obtain hemodynamic information on rat blood flows using the rat extracorporeal loop system without any noticeable adverse effect. The X-ray PIV technique combined with CO2 microbubbles ha...   내용 보기

Hybrid model for monitoring biophysical properties

Post Image A hybrid system is proposed for measurement of biophysical properties under ex vivo condition. The system is composed of an ultrasound system and a microfluidic device. The extracorporeal bypass loop consists of a pulse-free chamber (air cavity...   내용 보기

Speckle analysis for measurement of RBC aggregation

Post Image A simple microfluidic-based method is proposed to achieve sensitive detection of hyperaggregation. Given that formation of erythrocyte aggregation (EA) in the channel creates clear speckle patterns, the EA extent can be estimated by calculating a...   내용 보기
