A New and Improved Lucivid

 

For the first time ever a color microdisplay is available for your microscope.  The new Lucivid LED model let’s you see your head-down display projected over your specimen in color or monochrome.

The Lucivid is an innovative microdisplay that superimposes your computer monitor onto the microscope’s field of view.  Use the Lucivid to perform stereology with Stereo Investigator as well as accurately trace neurons with Neurolucida while you look through your microscope’s eyepieces with your computer’s monitor projected into your microscope.  You can also use the Lucivid for retinal stimulation to excite your retinal specimens by projecting computer generated graphics and patterns onto your specimen.

Smaller, lighter, and more durable than the previous model; the new Lucivid LED model is now available.  Find out more about the new Lucivid LED model on our website.

DHA Supplementation Prior to Brain Injury May Reduce Severity

Helmet, neck roll, shoulder pads, thigh pads, knee pads, mouth guard…  A football player’s list of protective gear goes on and on. New research suggests adding one more item to the list: DHA.

Formally known as docosahexaenoic acid, DHA is one of the human brain’s primary fatty acids. Essential for proper brain function, the omega-3 fatty acid is known to benefit patients with heart disease, cancer, and traumatic brain injuries. Researchers at the West Virginia University School of Medicine say DHA may also help lessen the blow to the brain when taken prior to a head injury.

In their study, the scientists examined the brains of a population of rats, which had received dietary supplementation of DHA for 30 days prior to a traumatic brain injury. They used the Optical Fractionator with Stereo Investigator to quantify the amyloid precursor protein-positive axons, a marker of injury in the brain. A stereological count of injured axons revealed a significantly decreased amount of APP-positive axons in the rats who had received DHA supplements.

In addition to stereological analysis, the researchers assessed the brain damage with immunohistochemistry and water maze testing. Each trial revealed evidence that supplemental DHA was beneficial in reducing the injury response.

“Our findings suggest that meaningful public health benefits are likely from increasing currently low dietary DHA omega-3 intakes in our population overall and, in particular, our at-risk populations,” say the authors.

Q&A: Dr. Daniel Peterson Discusses His Courses on Microscopy and Stereology

Talk of zebrafish and Spaceballs probes make Dr. Daniel Peterson’s microscopy and stereology courses sound intriguing. But Dr. Peterson says it’s the hands-on instruction that students enjoy most about the biannual workshops he teaches in Chicago. From August 15-19, 2011, the Associate Professor and Executive Director at the Center for Stem Cell and Regenerative Medicine at The Rosalind Franklin University of Medicine and Science, welcomes students to Chicago’s Club Quarters for five days of  instruction on all aspects of state-of-the-art microscopy, stereology, and histological analysis.

He spoke to us about the atmosphere in the classroom, what kinds of students take his course, and what aspects of the workshops participants get most excited about. Continue reading “Q&A: Dr. Daniel Peterson Discusses His Courses on Microscopy and Stereology” »

Washington University Researchers use Stereo Investigator to Study Axonal Transport in Parkinson’s Model

Journeying along axons, microscopic powerhouses known as mitochondria provide cells with the energy they need to function. When something goes wrong with the axonal transport and mitochondria isn’t delivered, the system fails, and the cell body dies.

Scientists in the Department of Anatomy and Neurobiology at the Washington University School of Medicine in St. Louis study the cellular bases of neurological disorders. Their recent research focuses on Parkinson’s disease and identifies impaired axonal transport as a possible key player in this neurological disorder.

The research group, of Dr. Karen L. O’Malley, Dr. Jeong Sook Kim-Han, and Dr. Jo Ann Antenor-Dorsey studied axonal transport in dopamine (DA) neurons in the mouse brain—the cells most affiliated with Parkinson’s disease. They localized cell axons by using a microchamber system that separated axons from cell bodies and dendrites. They also introduced 1-methyl-4-phenylpyridinium ion (MPP+), a toxin known to disrupt axonal function and mimic Parkinson’s disease.

Stereo Investigator helped them quantify TH-positive cell bodies and neurites. As early as 12 hours after MPP+ treatment, they saw breaks in axons. After 24 hours, they began to see a significant reduction in cell bodies. “This study underscores the necessity of developing therapeutics aimed at axons as well as cell bodies so as to preserve circuitry and function,” they say in their paper “The Parkinsonian Mimetic, MPP+, Specifically Impairs Mitochondrial Transport in Dopamine Axons, published in the Journal of Neuroscience.

The use of Stereo Investigator saved the researchers time and hard drive space, according to Dr. Kim-Han. “We used to count cells after acquiring images from a fluorescent microscope and saving it to a computer, which took long time and a lot of space on the computer,” she said. “Also, the data was more convincing since the area for counting was selected automatically with the number of fields assigned.”

Stereo Investigator Assists Stanford Stroke Center Scientists in Stem Cell Research

A stroke can leave its victim mentally and physically devastated. Recovery is demanding, and takes drive and determination. If the patient doesn’t receive medical attention within the small, critical window of time after the stroke occurs, chances of a quick recovery are slim. Developments in stem cell research find doctors optimistic about new possibilities for stroke rehabilitation.

Scientists at the Stanford Stroke Center, one of the leading centers for stroke research in the world, are working on figuring out how transplanted stem cells affect the host brain. They’re specifically working toward determining which trophic factors—substances secreted by cells—are necessary for stem cell transplantation to be effective. One recent study focused on vascular endothelial growth factor (VEGF), a factor associated with neurological recovery in stroke patients.

As described in their paper “Transplanted Stem Cell-secreted VEGF Effects Post-stroke Recovery, Inflammation, and Vascular Repair,” Drs. Nobutaka Horie, Gary Steinberg, and their team of researchers found VEGF to be essential for hCNS-SCns-induced recovery. The research team studied the brains of rats, which had undergone stroke surgery and were injected with human central nervous system stem cells (hCNS-SCns). After thorough analysis of various parameters, including stereological quantification of the brain inflammatory response and stem cell survival using Stereo Investigator, the Stanford team determined the stem cells helped suppress inflammation, helped form new blood vessels, and improved blood-brain barrier integrity.”

“Subacute cell transplantation therapy offers a multimodal strategy for brain repair that could significantly expand the therapeutic window for stroke,” say the authors in “Transplanted Stem Cell-secreted VEGF Effects Post-stroke Recovery, Inflammation, and Vascular Repair.”
