invivo 유세포분석기(flow cytometer)를 이용한 CTC의 공초점 탐지는 2004년 처음 실행되었고 이동식 장치는 좀더 최근에 소개되었다. 그림 a에서 invivo 유세포분석기에서 탐지된 혈중 GFP 양성 다발성 골수종 세포를 보여준다. 측정은 종양세포를 주입한 후 다양한 간격으로 60초 이상 걸렸다(각 다른 3일간의 실
In a full-hearted evensong
20 Of joy illimited;

인간과 동물로부터 분리한 섬유아세포(fiboblast)는 세포배양에서 계속 자라지 못하고 제한된 수의 분열을 한 후 성장을 정지하는데 이를 in vitro의 세포 복제의 노화(replicative senescence)라고 일컫는다(Hayflick 1965, 1977, Rohme 1981). in vitro에서 노화한 섬유아세포는 invivo에서 노화된 섬유아세포와 같은 형태를

1. Hydrostatic Pressure (10 pts)
Gate AB in the figure is a quarter circle (radius: R, width: w into the paper) and hinged at B. This gate holds the water
(density: �) on its right side. Find the force F just sufficient to keep the gate from opening. The gate is uniform and weighs
Mg. The gravitational acceleration is g.
A. Calculate the horizontal component of the press
