Immunocytochemical identification of peripheral sensory nerve fiber subtypes (and detection of protein expression therein) are key to the understanding of molecular mechanisms underlying peripheral sensation. Here we describe methods for preparation of peripheral/visceral tissue samples, such as skin and limb bones, for specific immunostaining of peripheral sensory nerve fibers.
Acute and Chronic Tactile Sensory Testing after Spinal Cord Injury in Rats
1Center for Brain and Spinal Cord Repair, School of Allied Medical Professions, The Ohio State University, 2Spinal Cord Research Center, Drexel University College of Medicine
We describe two tactile sensory testing methods for acute or chronic periods of spinal cord injury in rats. These validated procedures can detect the development and maintenance of allodynia-like sensations.
Chronic Constriction of the Sciatic Nerve and Pain Hypersensitivity Testing in Rats
School of Medical Sciences, University of New South Wales
Due to the simplicity of surgery and the robust behavioural outcome, chronic constriction of the sciatic nerve is one of the pre-eminent animal models of neuropathic pain. Within 24 hrs following surgery, pain hypersensitivity is established and can be quantitatively measured using a von Frey aesthesiometer (mechanical test) and plantar analgesia meter (thermal test).
An in vivo Rodent Model of Contraction-induced Injury and Non-invasive Monitoring of Recovery
1Department of Physiology, University of Maryland School of Medicine, 2Department of Orthopaedics, University of Maryland School of Medicine, 3Department of Diagnostic Radiology, University of Maryland School of Medicine
An in vivo animal model of injury is described. The method takes advantage of the subcutaneous position of the fibular nerve. Velocity, timing of muscle activation, and arc of motion are all pre-determined and synchronized using commercial software. Post injury changes are monitored in vivo using MR imaging/spectroscopy.
Platelet Adhesion and Aggregation Under Flow using Microfluidic Flow Cells
Fluxion Biosciences, Inc.
The platelet adhesion cascade takes place in the presence of shear flow, a factor not accounted for in conventional (static) well-plate assays. This article reports on a platelet-aggregation assay utilizing a microfluidic well-plate format to emulate physiological shear flow conditions.
Visualization of UV-induced Replication Intermediates in E. coli using Two-dimensional Agarose-gel Analysis
Department of Biology, Portland State University
We present a procedure by which two-dimensional agarose-gel analysis can be used to identify the structure of replication intermediates that occur following UV irradiation.
Corneal Confocal Microscopy: A Novel Non-invasive Technique to Quantify Small Fibre Pathology in Peripheral Neuropathies
Division of Cardiovascular Medicine, University of Manchester
Corneal Confocal microscopy is a non-invasive clinical technique which may be used to quantify C fibre damage to diagnose and stratify patients with increasing neuropathic severity.
Agrobacterium-Mediated Virus-Induced Gene Silencing Assay In Cotton
1Department of Biochemistry and Biophysics, Institute of Plant Genomics and Biotechnology, Texas A&M University, 2Department of Plant Pathology and Microbiology, Institute of Plant Genomics and Biotechnology, Texas A&M University
We present the detailed protocol for Agrobacterium-mediated virus-induced gene silencing (VIGS) assay in cotton. The tobacco rattle virus (TRV)-derived VIGS vectors were deployed to induce RNA silencing of cotton GrCLA1, Cloroplastos alterados 1 gene. The albino phenotype caused by silencing GrCLA1 was observed at the seedling stage within 2 weeks after inoculation.
A Multi-compartment CNS Neuron-glia Co-culture Microfluidic Platform
1Department of Electrical and Computer Engineering, Texas A&M University (TAMU), 2Department of Veterinary Integrative Biosciences, Texas A&M University (TAMU)
We developed a novel multi-compartment neuron co-culture microsystem platform for in vitro CNS axon-glia interaction research. The platform is capable of conducting up to six independent experiments in parallel and was fabricated using a newly developed macro/micro hybrid fabrication method.
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.
