In this paper we have shown that electrode polarization impedance (EPI) can be separated from measured tissue impedance as long as the characteristic frequencies of EPI and tissue are not too close, so that the EPI is largely displayed as a...

We present a novel method for localization of large blood vessels using a bioimpedance based needle positioning system on an array of ten monopolar needle electrodes. The purpose of the study is to develop a portable, low cost tool for rapi...
Cyclic Force Applied to FAs Induces Actin Recruitment Depending on the Dynamic Loading Pattern [0.03%]

Mechanical forces acting on focal adhesions (FAs) are believed to be an important determinant for cytoskeletal reorganization. However, the effect of the temporal pattern of forces on cellular responses has not been elucidated. In the prese...

Anesthesia drugs have impact on multiple outcomes of an anesthesia patient. Most typical outcomes include anesthesia depth, blood pressures, heart rates, etc. Traditional diagnosis and control in anesthesia focus on a one-drug-one-outcome s...
Patient-specific unicompartmental knee resurfacing arthroplasty: use of a novel interference lock to reduce tibial insert micromotion and backside wear [0.03%]
个性化单间室膝关节置换术：采用新型固定锁扣减少胫骨 Inserts 微动和背侧磨损

Micromotion has long been associated with wear of polyethylene tibial inserts, potentially causing failure of unicompartmental knee replacement systems. One cause of micromotion is the locking mechanism between the undersurface of the polye...
FEM Simulation of Non-Progressive Growth from Asymmetric Loading and Vicious Cycle Theory: Scoliosis Study Proof of Concept [0.03%]
非对称载荷与恶性循环理论下的非进展性生长有限元模拟：侧弯研究概念验证

Scoliosis affects about 1-3% of the adolescent population, with 80% of cases being idiopathic. There is currently a lack of understanding regarding the biomechanics of scoliosis, current treatment methods can be further improved with a grea...
High quality heart and lung auscultation system for diagnostic use on remote patients in real time [0.03%]

Over the last 30 years the process of in vitro fertilisation (IVF) has evolved considerably, yet the efficiency of this treatment remains relatively poor. The principal challenge faced by doctors and embryologists is the identification of t...
Anterior Cruciate Ligament Injury: Compensation during Gait using Hamstring Muscle Activity [0.03%]
前交叉韧带损伤的步态补偿机制及半膜肌活动变化规律研究

Paola Formento Catalfamo et al.
Previous research has shown that an increase in hamstring activation may compensate for anterior tibial transalation (ATT) in patients with anterior cruciate ligament deficient knee (ACLd); however, the effects of this compensation still re...
Macrophage Response to UHMWPE Submitted to Accelerated Ageing in Hydrogen Peroxide [0.03%]
