Scientists use Vesselucida 360 to quantify brain vasculature in mTBI model

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.

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

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.

American Association of Anatomists Launches Virtual Microscopy Database powered by Biolucida

Free resource for educators and researchers features thousands of downloadable histology slides

Educators and researchers around the world now have free access to a database of whole slide images (also known as virtual slides) for histology and pathology. Featuring thousands of virtual slides contributed by 15 universities, The Virtual Microscopy Database, VMD, (http://www.virtualmicroscopydatabase.org/) is an online resource that allows educators to view and download virtual images and share their own.

Powered by MBF Bioscience‘s Biolucida® for Medical Education solution, VMD gives educators an overview of individual slides and allows examination of various parts of the image at magnifications up to 40x. The users can take a screenshot or download the file at any time.

Funded by an Innovations Program Grant awarded by the American Association of Anatomists (AAA), the resource was developed by researchers from the University of Colorado, Drexel University College of Medicine, and the University of Michigan with corporate support from MBF Bioscience. With thousands of freely accessible virtual microscopy images, the VMD helps meet a growing need for better access to histology slides among educators and non-profit research organizations. The AAA foresees the images being used in a variety of educational ways such as for lectures, exams, and for creating supplementary course material as well as for non-profit research initiatives.

Collection of Virtual Slides in the Biolucida Viewer

“The greatest strength of the VMD is the availability of a large number of high quality virtual microscopy images to its users. The diversity and multiple examples of histological variations available in the VMD collections will enable histology and pathology educators to elevate the quality of their teaching by exposing their students to a broader variety of images and by experimenting with new pedagogical techniques in their classrooms.” (Lisa Lee, Ph.D., University of Colorado)

“We are proud to be part of the AAA’s efforts to improve the access of histology and pathology digital slides for medical educators and students by providing the underlying technology for this important resource. Any of the virtual slides in this new resource can be downloaded and used on an organization’s Biolucida on-premise or cloud-based server,” says Jack Glaser, president of MBF Bioscience.

Individuals affiliated with educational or research institutions may register to access the database. Once approved, users can browse files, or search for specific types of tissue. Currently, the VMD site includes over 2,600 virtual microscopy files, but as new users join the VMD file sharing community that number will grow as will the diversity of tissue and species type.

About AAA:

The American Association of Anatomists was founded by Joseph Leidy in Washington, D.C. in 1888 for the “advancement of anatomical science.” Today, via research, education, and professional development activities, AAA serves as the professional home for an international community of biomedical researchers and educators focusing on the structural foundation of health and disease.
