A CD4 enumeration method, the α-test, is described which uses whole saliva to provide rapid and accurate CD4 counts. The α-test costs pennies and eliminates the need for technical training, costly reagents such as monoclonal antibodies, instrumentation, refrigeration, transport of samples, as well as collection and handling of blood.
MicroRNA Detection in Prostate Tumors by Quantitative Real-time PCR (qPCR)
1Department of Laboratory Medicine & Pathobiology, University of Toronto, 2Division of Urology, Sunnybrook Health Sciences Centre, Toronto, Canada, 3Department of Anatomic Pathology, Sunnybrook Health Sciences Centre, Toronto, Canada, 4Biological Sciences, Sunnybrook Research Institute
Quantitative Real Time polymerase chain reaction (qPCR) is a rapid and sensitive method to investigate the expression levels of various microRNA (miRNA) molecules in tumor samples. Using this method expression of hundreds of different miRNA molecules can be amplified, quantified, and analyzed from the same cDNA template.
A Murine Model of Muscle Training by Neuromuscular Electrical Stimulation
1Department of Physical Medicine and Rehabilitation, University of Pittsburgh , 2Department of Physical Therapy, University of Pittsburgh , 3McGowan Institute for Regenerative Medicine, University of Pittsburgh
A murine model of neuromuscular electrical stimulation (NMES), a safe and inexpensive clinical modality, to the anterior compartment muscles is described. This model has the advantage of modifying a readily available clinical device for the purpose of eliciting targeted and specific muscle contractions in mice.

This video shows a model to study the development of intimal hyperplasia after stent deployment using a human vessel (IMA) in an immunodeficient rat model.
Quantification of Atherosclerotic Plaque Activity and Vascular Inflammation using [18-F] Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (FDG-PET/CT)
1Division of Cardiovascular Medicine, University of Pennsylvania, Perelman School of Medicine, 2Department of Radiology, University of Pennsylvania, Perelman School of Medicine, 3Department of Dermatology, University of Pennsylvania, Perelman School of Medicine
There is great need to identify atherosclerosis non-invasively, and here we demonstrate how FDG-PET/CT can be used to detect and quantify atherosclerotic plaque activity and vascular inflammation.
A Simplified Technique for Producing an Ischemic Wound Model
Department of Surgery, University of Louisville
We have developed a minimally invasive technique to create a rabbit ischemic ear wound model by dividing the central artery and nerve and the cranial neurovascular bundle. A subcutaneous tunnel then cuts all subcutaneous tissues. This procedure causes minimal skin disruption and can be safely used in diabetic animals.
Identification and Isolation of Slow-Dividing Cells in Human Glioblastoma Using Carboxy Fluorescein Succinimidyl Ester (CFSE)
1Department of Neurosurgery, The University of Florida, 2Department of Anatomical Sciences, Shiraz University of Medical Sciences, Shiraz, Iran
This video protocol demonstrates the application of the fluorescent dye carboxyfluorescein succinimidyl ester (CFSE) for the identification and separation of different sub-populations of cells in human glioblastoma based on frequency of cell division.
The Use of Pharmacological-challenge fMRI in Pre-clinical Research: Application to the 5-HT System
1Department of Radiology, Brain Imaging Center, Academic Medical Center Amsterdam, 2Biological Imaging Centre, MRC Clinical Sciences Centre, Imperial College London
The goal of this technique is to assess serotonin (5-HT) neurotransmitter function in the live and free-breathing animal with pharmacological magnetic resonance imaging (phMRI) and an intravenous challenge with a selective serotonin reuptake inhibitor (SSRI), fluoxetine.
Epidural Intracranial Pressure Measurement in Rats Using a Fiber-optic Pressure Transducer
Biomedical Sciences and Pharmacy, The University of Newcastle
A novel technique to record the pressures within the skull is described. The minimally invasive method uses a fibre-optic pressure sensing system to accurately measure intracranial pressure (ICP) in anaesthetized rats without causing significant brain trauma. The technique may be used in a wide range of experimental models.
The Polyvinyl Alcohol Sponge Model Implantation
1Department of Pathology, Microbiology and Immunology, Vanderbilt University School of Medicine, 2The Department of Veterans Affairs Medical Center, 3Internal Medicine, Vanderbilt University School of Medicine
A useful tool to analyze the effects of drugs, growth factors, and/or manipulated cells in an animal model of wound repair is described. This technique utilizes the properties of a polyvinyl alcohol (PVA) sponge to deliver and contain the desired treatment and also provide a platform to be excised and analyzed.
