Tri-layered Electrospinning to Mimic Native Arterial Architecture using Polycaprolactone, Elastin, and Collagen: A Preliminary Study
1Department of Biomedical Engineering, Virginia Commonwealth University, 2Department of Anatomy and Neurobiology, Virginia Commonwealth University, 3Department of Cardiovascular Surgery, University Hospital of Geneva
The aim of this study was to mimic the native three layered architecture of the arterial wall. To accomplish this, electrospinning was employed with the use of a 3-1 (input-output) nozzle and blends of polycaprolactone, elastin, and collagen.
An ex-ovo Chicken Embryo Culture System Suitable for Imaging and Microsurgery Applications
1Department of Biomedical Engineering, Cornell University, 2Current Address: Mechanical Engineering Department, Dogus University
In this article, we present a simple methodology to enable long-term ex-ovo avian embryo culture. This technique is ideal for longitudinal experimentation requiring complete optical accessibility and/or sterile transportation in avian embryos.
Reverse Total Shoulder Arthroplasty
Department of Orthopaedic Surgery – Division of Shoulder and Elbow Surgery, Case Western Reserve University
Reverse total shoulder arthroplasty is indicated for the treatment of conditions that cannot be treated with conventional arthroplasty or other procedures. These primarily include degenerative and incapacitating conditions with irreparable rotator cuff and loss of the normal biomechanical coupling of the shoulder.
Characterization of the Isolated, Ventilated, and Instrumented Mouse Lung Perfused with Pulsatile Flow
Department of Biomedical Engineering, University of Wisconsin – Madison
The following protocol outlines the process of isolating, ventilating and instrumenting mouse lungs to measure steady or pulsatile pulmonary vascular pressure-flow relationships in order to quantify the effects of blood flow, airflow, airway changes and vascular changes on right ventricular afterload.
Monitoring the Wall Mechanics During Stent Deployment in a Vessel
Department of Mechanical and Materials Engineering, University of Nebraska-Lincoln
Stent-induced arterial strain distributions are characterized using an optical surface strain measurement system. This visualization technique is used to gain insights into the impact of stent implantation on the host vessel.
Kinematics and Ground Reaction Force Determination: A Demonstration Quantifying Locomotor Abilities of Young Adult, Middle-aged, and Geriatric Rats
1CullenWebb Animal Neurology & Ophthalmology Center, Riverview, NB, 2Department of Clinical Neurosciences, Faculty of Medicine, University of Calgary, 3Department of Comparative Biology and Experimental Medicine, University of Calgary, 4Department of Neuroscience, University of Calgary
Locomotion is often examined as a behavioural outcome in various models of disease in fields such as neuroscience and orthopedics. This video paper intends to describe a method for collecting ground reaction forces and kinematics from rats during unrestrained locomotion.
Methods to Quantify Pharmacologically Induced Alterations in Motor Function in Human Incomplete SCI
1Sensory Motor Performance Program, Rehabilitation Institute of Chicago, 2Department of Kinesiology and Nutrition, University of Illinois at Chicago, 3Department of Physical Therapy, University of Illinois at Chicago
This video demonstrates modulation of reflex activity, volitional strength and ambulation through clinical and quantitative assessments in individuals with motor incomplete SCI as a result of acute oral administration of a serotonin reuptake inhibitor (SSRI).
Preparation of Rat Tail Tendons for Biomechanical and Mechanobiological Studies
Groupe PERSEUS, Faculté de Génie Département de génie mécanique, Université de Sherbrooke
This article describes the experimental procedures used to prepare rat tail tendons for biomechanical and mechanobiological studies. Several features of the main steps in preparation are demonstrated, beginning with extraction, cross-sectional area measurement, rinsing and loading into the bioreactor chamber.
Shape Memory Polymers for Active Cell Culture
Department of Biomedical and Chemical Engineering, Syracuse Biomaterials Institute
A method for developing cell culture substrates with the ability to change topography during culture is described. The method makes use of smart materials known as shape memory polymers that have the ability to memorize a permanent shape. This concept is adaptable to a wide range of materials and applications.
Synthetic, Multi-Layer, Self-Oscillating Vocal Fold Model Fabrication
Department of Mechanical Engineering, Brigham Young University
The methodology for fabricating synthetic vocal fold models is described. The models are life-sized and mimic the multi-layer structure of the human vocal folds. Results show the models to self-oscillate at pressures comparable to lung pressure and demonstrate flow-induced vibratory responses that are similar to those of human vocal folds.
