Spinal decompression sickness:hydrophobic protein and lamellar bodies in spinal tissue
decompression animal sheep
2009/6/12
Four basic studies have addressed the question of why the spinal cord is so vulnerable to decompression injury, with symptoms exceeding those related to the brain by a ratio often quoted as 3:1. Hydro...
Release of surfactant and a myelin proteolipid apoprotein in spinal tissue by decompression
animal bovine
2009/6/12
Two experiments have been performed on sections of bovine spinal cord, the first demonstrating that surface-active phospholipid (SAPL) and myelin proteolipid protein (PLP) are released by bubbles prod...
Material Properties Estimation of Living Soft Tissue Based on MR Images and Iterative FE Analysis
soft tissue material property MRI FEM
2009/6/9
This paper presents a method of material properties estimation for highly accurate finite element analysis of living soft tissue. It employs a compression test inside MRI in order to visualize the def...
In situ Observation of Biological Tissue in Laser Ablation Using Optical Coherence Tomography
laser ablation in situ observation of biological tissue surface optical coherence tomography ablation rate
2009/6/9
When conducting laser ablation of biological tissue, a tomography of the tissue surface is necessary to measure the crater shape and crater depth, and observe damage to the surrounding tissue. In thi...
Fundamental Study of a Non-contact Measurement of the Viscoelastic Property of the Body Surface Tissue
non-contact measurement viscoelastic property elastic modulus coefficient of viscosity
2009/6/9
In this study, we investigate the fundamental validity of this system. This method employs compressed air pressure to apply pressure to an area (6 mm in diameter) on the body surface. The deformation...
Simulation of Soft Tissue Ablation for a VR Simulator
ablation FEM-based soft tissue model maximum shearing stress hypothesis
2009/6/9
In surgery, failure of ablation is fatal to patients, and the operation is difficult for residents to learn. Our study aims to provide a VR-based training environment for ablation. This paper presents...
Influence of Tissue Inhomogeneity on Eddy Current Distribution in Magnetic Stimulation Therapy for Urinary Incontinence—Using Threedimensional Experimental and Computer Models—
magnetic stimulation current distribution inhomogeneity abdomen model
2009/6/9
The effect of magnetic stimulation for the treatment of urinary incontinence has been explained as a re-activation of lost functions of the pelvic floor muscles. A model study was used to investigate ...
Because of technological advances in tissue oximetry, clinicians and scientists have a better understanding of the role of oxygen in wound healing. In wound care and hyperbaric medicine applications, ...
Effect of caffeine consumption on tissue oxygen levels during hyperbaric oxygen treatment
transcutaneous oxygen hyperbaric air chamber
2009/6/8
Ten men were exposed to hyperbaric oxygen (HBO2), and their tissue oxygen levels were monitored after they drank either placebo or caffeine beverages. Transcutaneous tissue oxygen (PtcO2) monitor meas...
Elasticity Imaging of Soft Tissue
elasticity imaging contact impedance method palpation equivalent mass
2009/6/8
Elasticity imaging of soft tissue with contact impedance method was performed to quantify medical palpation. Frequency changes of piezoelectric vibrator in contact with soft tissue depends on the elas...
A deep stop during decompression from 82 fsw (25 m) significantly reduces bubbles and fast tissue gas tensions
Atmospheric Pressure Decompression Diving Humans
2009/6/4
In spite of many modifications to decompression algorithms, the incidence of decompression sickness (DCS) in scuba divers has changed very little. The success of stage, compared to linear ascents, is ...
Tissue nitrogen elimination in oxygen-breathing pigs is enhanced by fluorocarbon-derived intravascular micro-bubbles
Algorithms Analysis of Variance Fluorocarbons administration dosage animal Microbubbles
2009/6/3
The present study tested the hypothesis that intravascular micro bubbles generated by i.v. infusion of a 2 % dodecafluoropentane (DDFP) emulsion will enhance tissue denitrogenation during oxygen breat...
Gender differences in human skeletal muscle and subcutaneous tissue gases under ambient and hyperbaric oxygen conditions
Hyperbaric Oxygenation gender human skeletal muscle subcutaneous tissue Gas tensions resting conditions
2009/6/2
The purpose of this study is to ascertain if gender differences exist in human skeletal muscle (MM) and subcutaneous (SC) tissue gases using monoplace and multiplace hyperbaric oxygen (HBO2) treatment...
Rate of delivery of hyperbaric oxygen treatments does not affect response in soft tissue radionecrosis
hyperbaric oxygenation Soft tissue radiation necrosis radionecrosis angiogenesis treatment response gastrointestinal tract bladder
2009/6/2
Soft tissue radiation necrosis (STRN) is effectively treated with hyperbaric oxygen (HBO,), believed to result from stimulation of angiogenesis in radiation-injured tissue. Thirty to forty HBO2 treatm...
Development of Bio-actuator with Tissue-engineered Skeletal Muscle Regenerated on Acellular Tissue and Collagen Gel
tissue-engineered skeletal muscle bio-actuator, C2C12 cell, photofabrication isometric contractile force
2009/6/2
A tissue-engineered muscle has a potential to realize a flexible actuator with high efficiency as a bioactuator, whereas mechanical actuators currently used are inflexible and low efficiency. In this ...
