Blood-Brain Barrier Chip: in vivo-like drug and antibody transport

17.06.2019

Like airport security barriers that either clear authorized travelers or block unauthorized travelers and their luggage from accessing central operation areas, the blood-brain-barrier (BBB) tightly controls the transport of essential nutrients and energy metabolites into the brain and staves off unwanted substances circulating in the blood stream.

VR: visualize expansion microscopy data and illuminate new treatments

17.06.2019

A combined research team from Carnegie Mellon University and Benaroya Research Institute at Virginia Mason is pairing a nanoscale imaging technique with virtual reality (VR) technology to create a method that allows researchers to "step inside" their biological data.

World Blood Donation Day: A small drop saves lives

14.06.2019

Donating blood - the World Blood Donation Day has been held annually since 2004 on 14th June, the birthday of Karl Landsteiner, discoverer of blood groups. The day is intended to make people all over the world aware of the relevance of blood donations and donors. But what significance does blood donation have for human health? What activities will take place on this day?

Computational system: tool pinpoints gut's bacteria

14.06.2019

A UCLA-led research team has developed a faster and more accurate way to determine where the many bacteria that live in, and on, humans come from. Broadly, the tool can deduce the origins of any microbiome, a localized and diverse community of microscopic organisms.

AI: diagnosis of skin lesions is superior to humans

13.06.2019

When it comes to the diagnosis of pigmented skin lesions, artificial intelligence is superior to humans. In a study conducted under the supervision of the MedUni Vienna human experts "competed" against computer algorithms. The algorithms achieved clearly better results, yet their current abilities cannot replace humans.

Wound healing: Molecular bait for hydrogels

12.06.2019

The team led by Brown School of Engineering bioengineer Antonios Mikos and graduate student Jason Guo have developed modular, injectable hydrogels enhanced by bioactive molecules anchored in the chemical crosslinkers that give the gels structure.

Machine learning: superior results for low-dose CT

12.06.2019

Machine learning has the potential to vastly advance medical imaging, particularly computerized tomography (CT) scanning, by reducing radiation exposure and improving image quality. Those new research findings were just published in Nature Machine Intelligence by engineers at Rensselaer Polytechnic Institute and radiologists at Massachusetts General Hospital and Harvard Medical School.

Ultrasound: restoring dopaminergic pathway at Parkinson's

11.06.2019

While there are several thousand drugs available to treat brain diseases, they cannot penetrate the blood-brain barrier (BBB) into the brain. The BBB, which protects the brain from pathogens, also prevents most drugs from gaining access to the brain functional tissue, a well-known challenge to the treatment of all brain diseases including neurodegenerative disorders like Parkinson's disease.
