Scientists use Vesselucida 360 to quantify brain vasculature in mTBI model

Posted on March 11, 2019 by MBF Bioscience

It is not uncommon for war veterans returning home from war-zones like Iraq and Afghanistan to suffer from blast-induced traumatic brain injuries (TBI). In these situations, the most common types of blasts are lower level blasts, the kind that produce mild TBIs (mTBI). Though the effects of a mTBI aren’t visible from the outside, scientists say the blood vessels inside the brain are deeply altered.

In their study of a mouse model of mTBI that mimics the blast exposure associated with human mild TBI, a research team, that includes MBF Bioscience Scientific Director Dr. Susan Tappan, say that low-level blast exposure disrupts the way cells interact with each other within the brain’s neurovascular unit.

Fig:1 Chronic vascular pathology in blast-exposed rats revealed by micro-CT scanning. Two control and two blast-exposed rats were transcardially perfused with the Brite Vu contrast agent at 10 months after blast exposure. Brains were scanned at a resolution of 7.5 μm using equispaced angles of view around 360°, and 3D reconstructions were prepared with Bruker’s CTVox 3D visualization software. a-d MIP images of volume-rendered brain vasculature from two control (a, b) and two blast-exposed (c, d) rats revealed diffuse thinning of the brain vasculature in the blast-exposed rats.

Scale bars, 1 mm for (e-h), and 0.6mm for (o-p). i-n Reconstructions of coronal optical sections from the brains of control (i, k) and blast-exposed (j, l) animals. Panels (i) and (j) correspond approximately to coordinates interaural 12.24–9.48 mm and panels (k) and (l) correspond approximately to coordinates interaural 6.94–3.24 mm. Lateral views of (i) and (j) are shown in (m) and (n), respectively. Vessels were color coded to allow visualization of individual vessels automatically traced by the Vesselucida 360 software. Note the general loss of radial organization in the blast-exposed shown in panel (j). Scale bar, 1 mm for (i-n)

Aiming to mimic an event often experienced by soldiers and military personnel in war-torn regions, the scientists exposed rats to a series of three blasts — one blast per day, over three consecutive days. Though the rats developed behaviors typical to chronic PTSD, their neuronal pathology, at least at the light and electron microscopy levels remained unchanged, according to the study. However, when the researchers examined the rat brains on a vascular level, they found evidence of chronic damage.

MBF Bioscience receives NIH funding to support innovative research program on the peripheral nervous system

Posted on January 8, 2019 by MBF Bioscience

FOR IMMEDIATE RELEASE

MBF Bioscience Williston, VT – January 9, 2019 – MBF Bioscience is pleased to announce our participation in the Stimulating Peripheral Activity to Relieve Conditions (SPARC) program. Funded by the National Institutes of Health (NIH), this extensive research initiative is a vast collaborative effort, which aims to deepen the understanding of how the peripheral nervous system impacts internal organ function.

“We are honored to be working in collaboration with over 40 research teams in the United States and around the world who are making revolutionary discoveries about how the network of nerves located outside the brain and spinal cord affect organs such as the heart, stomach, and bladder, and what role these nerves play in diseases like hypertension and type II diabetes as well as gastrointestinal and inflammatory disorders,” says Jack Glaser, President of MBF Bioscience.

To facilitate this important research, MBF Bioscience will provide the collaborating research scientists with both software and support. Specifically, we will provide image segmentation tools developed to handle large and diverse amounts of scientific image data. Software applications such as Neurolucida 360^®, Tissue Mapper™ and Tissue Maker™ will enable researchers to image and analyze nerves, tissues, and entire organs in 2D and 3D.

“Representing the innervation patterns accurately and robustly is an essential contribution to the generation of representative models that can be used for simulations. We are working with our partners at the University of Auckland, under the direction of Professor Peter Hunter, to create these models for each organ system that will be an enduring resource for scientists for years to come,” says Susan Tappan, Scientific Director at MBF Bioscience.

Researchers involved in the SPARC program are making important advances in health and medicine, which may lead to the development of new therapies for managing an array of illnesses and disorders. Some examples of research areas include subcutaneous nerve stimulation for arrhythmia control, sensory neuromodulation of the esophagus, and mapping of the neural circuitry of bone marrow. We are thrilled about this opportunity to work in partnership with such an impressive array of research teams on this ground-breaking project.

About SPARC

Stimulating Peripheral Activity to Relieve Conditions (SPARC) is a National Institutes of Health (NIH) program that focuses on understanding peripheral nerves — nerves that connect the brain and spinal cord to the rest of the body — and how their electrical signals control internal organ function. Methods and medical devices that modulate these nerve signals are a potentially powerful way to treat many diseases and conditions, such as hypertension, heart failure, gastrointestinal disorders, type II diabetes, inflammatory disorders, and more.
