Canada’s Nanorobotics Laboratory unveils its ‘medical interventional infrastructure’

Leave a reply

Located at the Polytechnique Montréal (Canada), the Nanorobotics Laboratory has built a one-of-a-kind ‘medical interventional infrastructure’, the result of a $4.6M investment from various levels of government and from private enterprise.

Before getting to the news release, here’s a video featuring Prof. Sylvain Martel who discusses his work by referencing the movie, Fantastic Voyage. There are subtitles for those whose French fails them,

From an Aug. 24, 2016 Polytechnique Montréal news release (also on EurekAlert),

Fifty years to the day after the film Fantastic Voyage was first shown in theatres, the Polytechnique Montréal Nanorobotics Laboratory is unveiling a unique medical interventional infrastructure devoted to the fight against cancer. The outcome of 15 years of research conducted by Professor Sylvain Martel and his team, it enables microscopic nanorobotic agents to be guided through the vascular systems of living bodies, delivering drugs to targeted areas.

An action-packed 100,000-kilometre journey in the human body

Fantastic Voyage recounted the adventure of a team of researchers shrunk to microscopic size who, aboard a miniature submarine, travelled into a patient’s body to conduct a medical operation in a surgically inoperable area. This science fiction classic has now been eclipsed by procedures and protocols developed by Professor Martel’s multidisciplinary team comprising engineers, scientists and experts from several medical specialties working together on these projects that herald the future of medicine.

“Our work represents a new vision of cancer treatments, with our goal being to develop the most effective transportation systems for the delivery of therapeutic agents right to tumour cells, to areas unreachable by conventional treatments,” says Professor Martel, holder of the Canada Research Chair in Medical Nanorobotics and Director of the Polytechnique Montréal Nanorobotics Laboratory.

Conveying nanorobotic agents into the bloodstream to reach the targeted area right up to the tiniest capillaries without getting lost in this network stretching about 100,000 kilometres—two-and-a-half times the Earth’s circumference—is a scenario that has been turned into reality. This is an adventure-filled journey for these microscopic vehicles that must confront the powerful onslaught of arterial blood flow, the mazes of the vascular network and the narrowness of the capillaries—just like the film’s heroes!

“Doctors” invisible to the naked eye

To conduct this fantastic voyage, Professor Martel’s team is developing various procedures, often playing a pioneering role. These include navigating carriers just a fraction of the thickness of a hair through the arteries using a clinical magnetic resonance imaging (MRI) platform, the first in the world to achieve this in a living organism, in 2006. This exploit was followed in 2011 by the guidance of drug-loaded micro-transporters into the liver of a rabbit.

Limits to the miniaturization of artificial nanorobots prevent them from penetrating the smallest blood vessels, however. For this, Professor Martel plans to have them play the role of Trojan horses, enclosing an “army” of special bacteria loaded with drugs that they will release at the edges of these small vessels.

Able to follow paths smaller than a red blood cell, these self-propelled bacteria move at high speed (200 microns per second, or 200 times their size per second). Once they are inside a tumour, they are able to naturally detect hypoxic (oxygen-starved) zones, which are the most active zones and the hardest to treat by conventional means, including radiotherapy, and then deliver the drug.

Professor Martel’s team has succeeded in using this procedure to administer therapeutic agents in colorectal tumours in mice, guiding them through a magnetic field. This has just been the subject of an article in the renowned journal Nature Nanotechnology, titled Magneto-gerotactic Bacteria Deliver Drug-containing Nanoliposomes to Tumour Hypoxic Regions. “This advanced procedure, which provides optimal targeting of a tumour while preserving surrounding healthy organs and tissue, unlike current chemotherapy or radiotherapy, heralds a new era in cancer treatment,” says Dr. Gerald Batist, Director of the McGill Centre for Translational Research in Cancer, based at the Jewish General Hospital, which is collaborating on the project.

Professor Martel’s projects also focus on the inaccessibility of certain parts of the body, such as the brain, to transporting agents. In 2015, his team also stood out by successfully opening a rat’s blood-brain barrier, temporarily and without damage, providing access to targeted areas of the brain. This feat was achieved through a slight rise in temperature caused by exposing nanoparticles to a radiofrequency field.

“At present, 98% of drug molecules cross the blood-brain barrier only with great difficulty,” notes Dr. Anne-Sophie Carret, a specialist in hematology-oncology at Montréal’s Centre hospitalier universitaire Sainte-Justine and one of the doctors collaborating on the project. “This means surgery is often the only way to treat some patients who have serious brain diseases. But certain tumours are inoperable because of their location. Radiation therapy, for its part, is not without medium- and long-term risk for the brain. This work therefore offers real hope to patients suffering from a brain tumour.”

Here’s who invested, how much they invested, and what the Nanorobotics Laboratory got for its money,

This new investment in the Nanorobotics Laboratory represents $4.6 million in infrastructure, with contributions of $1.85 million each from the Canada Foundation for Innovation (CFI), and the Government of Québec. Companies including Siemens Canada and Mécanik have also made strategic contributions to the project. This laboratory now combines platforms to help develop medical protocols for transferring the procedures developed by Professor Martel to a
clinical setting.

The laboratory contains the following equipment:

  • a clinical MRI platform to navigate microscopic carriers directly into specific areas in the vascular system and for 3D visualization of these carriers in the body;
  • a specially-developed platform that generates the required magnetic field sequences to guide special bacteria loaded with therapeutic agents into tumours;
  • a robotic station (consisting of a robotized bed) for moving a patient from one platform to another;
  • a hyperthermia platform for temporary opening of the blood-brain barrier;
  • a mobile X-ray system;
  • a facility to increase the production of these cancer-fighting bacteria.

Sylvain Martel’s most recent work with nanorobotic agents (as cited in the news release) was featured here in an Aug. 16, 2016 post.

Interconnected performance analysis music hub shared by McGill University and Université de Montréal announced* June 2, 2016

Leave a reply

The press releases promise the Centre for Interdisciplinary Research in Music Media and Technology (CIRMMT) will shape the future of music. The CIRMMT June 2, 2016 (Future of Music) press release (received via email) describes the funding support,

A significant investment of public and private support that will redefine the future of music research in Canada by transforming the way musicians compose,listen and perform music.

The Centre for Interdisciplinary Research in Music Media and Technology (CIRMMT), the Schulich School of Music of McGill University and the Faculty of Music of l’Université de Montréal are creating a unique interconnected research hub that will quite literally link two exceptional spaces at two of Canada’s most renowned music schools.

Imagine a new space and community where musicians, scientists and engineers join forces to gain a better understanding of the influence that music plays on individuals as well as their physical, psychological and even neurological conditions; experience the acoustics of an 18th century Viennese concert hall created with the touch of a fingertip; or attending an orchestral performance in one concert hall but hearing and seeing musicians performing from a completely different venue across town… All this and more will soon become possible here in Montreal!

The combination of public and private gifts will broaden our musical horizons exponentially thanks to significant investment for music research in Canada. With over $14.5 million in grants from the Canada Foundation for Innovation (CFI), the Government of Quebec and the Fonds de Recherche du Québec (FRQ), and a substantial contribution of an additional $2.5million gift from private philanthropy.

“We are grateful for this exceptional investment in music research from both the federal and provincial governments and from our generous donors,” says McGill Principal Suzanne Fortier. “This will further the collaboration between these two outstanding music schools and support the training of the next generation of music researchers and artists. For anyone who loves music, this is very exciting news.”

There’s not much technical detail in this one but here it is,

Digital channels coupling McGill University’s Music Multimedia Room (MMR – a large, sound-isolated performance lab) and l’Université de Montréal’s Salle Claude Champagne ([SCC -] a superb concert hall) will transform these two exceptional spaces into the world’s leading research facility for the scientific study of live performance, movement of recorded sound in space, and distributed performance (where musicians in different locations perform together).

“The interaction between scientific/technological research and artistic practice is one of the most fruitful avenues for future developments in both fields. This remarkable investment in music research is a wonderful recognition of the important contributions of the arts to Canadian society”, says Sean Ferguson, Dean of Schulich School of Music

The other CIRMMT June 2, 2016 (Collaborative hub) press  release (received via email) elaborates somewhat on the technology,

The MMR (McGill University’s Music Multimedia Room) will undergo complete renovations which include the addition of high quality variable acoustical treatment and a state-of-the-art rigging system. An active enhancement and sound spatialization system, together with stereoscopic projectors and displays, will provide virtual acoustic and immersive environments. At the SCC (l’Université de Montréal’s Salle Claude Champagne), the creation of a laboratory, a control room and a customizable rigging system will enable the installation and utilization of new research equipment’s in this acoustically-rich environment. These improvements will drastically augment the research possibilities in the hall, making it a unique hub in Canada for researchers to validate their experiments in a real concert hall.

“This infrastructure will provide exceptional spaces for performance analysis of multiple performers and audience members simultaneously, with equipment such as markerless motion-capture equipment and eye trackers. It will also connect both spaces for experimentations on distributed performances and will make possible new kinds of multimedia artworks.

The research and benefits

The research program includes looking at audio recording technologies, audio and video in immersive environments, and ultra-videoconferencing, leading to the development of new technologies for audio recording, film, television, distance education, and multi-media artworks; as well as a focus on cognition and perception in musical performance by large ensembles and on the rhythmical synchronization and sound blending of performers.

Social benefits include distance learning, videoconferencing, and improvements to the quality of both recorded music and live performance. Health benefits include improved hearing aids, noise reduction in airplanes and public spaces, and science-based music pedagogies and therapy. Economic benefits include innovations in sound recording, film and video games, and the training of highly qualified personnel across disciplines.

Amongst other activities they will be exploring data sonification as it relates to performance.

Hopefully, I’ll have more after the livestreamed press conference being held this afternoon, June 2, 2016,  (2:30 pm EST) at the CIRMMT.

*’opens’ changed to ‘announced’ on June 2, 2016 at 1335 hours PST.

ETA June 8, 2016: I did attend the press conference via livestream. There was some lovely violin played and the piece proved to be a demonstration of the work they’re hoping to expand on now that there will be a CIRMMT (pronounced kermit). There was a lot of excitement and I think that’s largely due to the number of years it’s taken to get to this point. One of the speakers reminisced about being a music student at McGill in the 1970s when they first started talking about getting a new music building.

They did get their building but have unable to complete it until these 2016 funds were awarded. Honestly, all the speakers seemed a bit giddy with delight. I wish them all congratulations!

Montreal Neuro goes open science

Leave a reply

The Montreal Neurological Institute (MNI) in Québec, Canada, known informally and widely as Montreal Neuro, has ‘opened’ its science research to the world. David Bruggeman tells the story in a Jan. 21, 2016 posting on his Pasco Phronesis blog (Note: Links have been removed),

The Montreal Neurological Institute (MNI) at McGill University announced that it will be the first academic research institute to become what it calls ‘Open Science.’  As Science is reporting, the MNI will make available all research results and research data at the time of publication.  Additionally it will not seek patents on any of the discoveries made on research at the Institute.

…

Will this catch on?  I have no idea if this particular combination of open access research data and results with no patents will spread to other university research institutes.  But I do believe that those elements will continue to spread.  More universities and federal agencies are pursuing open access options for research they support.  Elon Musk has opted to not pursue patent litigation for any of Tesla Motors’ patents, and has not pursued patents for SpaceX technology (though it has pursued litigation over patents in rocket technology). …

Montreal Neuro and its place in Canadian and world history

Before pursuing this announcement a little more closely, you might be interested in some of the institute’s research history (from the Montreal Neurological Institute Wikipedia entry and Note: Links have been removed),

The MNI was founded in 1934 by the neurosurgeon Dr. Wilder Penfield (1891–1976), with a $1.2 million grant from the Rockefeller Foundation of New York and the support of the government of Quebec, the city of Montreal, and private donors such as Izaak Walton Killam. In the years since the MNI’s first structure, the Rockefeller Pavilion was opened, several major structures were added to expand the scope of the MNI’s research and clinical activities. The MNI is the site of many Canadian “firsts.” Electroencephalography (EEG) was largely introduced and developed in Canada by MNI scientist Herbert Jasper, and all of the major new neuroimaging techniques—computer axial tomography (CAT), positron emission tomography (PET), and magnetic resonance imaging (MRI) were first used in Canada at the MNI. Working under the same roof, the Neuro’s scientists and physicians made discoveries that drew world attention. Penfield’s technique for epilepsy neurosurgery became known as the Montreal procedure. K.A.C. Elliott identified γ-aminobutyric acid (GABA) as the first inhibitory neurotransmitter. Brenda Milner revealed new aspects of brain function and ushered in the field of neuropsychology as a result of her groundbreaking study of the most famous neuroscience patient of the 20th century, H.M., who had anterograde amnesia and was unable to form new memories. In 2007, the Canadian government recognized the innovation and work of the MNI by naming it one of seven national Centres of Excellence in Commercialization and Research.

For those with the time and the interest, here’s a link to an interview (early 2015?) with Brenda Milner (and a bonus, related second link) as part of a science podcast series (from my March 6, 2015 posting),

Dr. Wendy Suzuki, a Professor of Neural Science and Psychology in the Center for Neural Science at New York University, whose research focuses on understanding how our brains form and retain new long-term memories and the effects of aerobic exercise on memory. Her book Healthy Brain, Happy Life will be published by Harper Collins in the Spring of 2015.

  • Totally Cerebral: Untangling the Mystery of Memory: Neuroscientist Wendy Suzuki introduces us to scientists who have uncovered some of the deepest secrets about our brains. She begins by talking with experimental psychologist Brenda Milner [interviewed in her office at McGill University, Montréal, Quebéc], who in the 1950s, completely changed our understanding of the parts of the brain important for forming new long-term memories.
  • Totally Cerebral: The Man Without a Memory: Imagine never being able to form a new long term memory after the age of 27. Welcome to the life of the famous amnesic patient “HM”. Neuroscientist Suzanne Corkin studied HM for almost half a century, and gives us a glimpse of what daily life was like for him, and his tremendous contribution to our understanding of how our memories work.

Brief personal anecdote
For those who just want the science, you may want to skip this section.

About 15 years ago, I had the privilege of talking with Mary Filer, a former surgical nurse and artist in glass. Originally from Saskatchewan, she, a former member of Wilder Penfield’s surgical team, was then in her 80s living in Vancouver and still associated with Montreal Neuro, albeit as an artist rather than a surgical nurse.

Penfield had encouraged her to pursue her interest in the arts (he was an art/science aficionado) and at this point her work could be seen many places throughout the world and, if memory serves, she had just been asked to go MNI for the unveiling of one of her latest pieces.

Her husband, then in his 90s, had founded the School of Architecture at McGill University. This couple had known all the ‘movers and shakers’ in Montreal society for decades and retired to Vancouver where their home was in a former chocolate factory.

It was one of those conversations, you just don’t forget.

More about ‘open science’ at Montreal Neuro

Brian Owens’ Jan. 21, 2016 article for Science Magazine offers some insight into the reason for the move to ‘open science’,

Guy Rouleau, the director of McGill University’s Montreal Neurological Institute (MNI) and Hospital in Canada, is frustrated with how slowly neuroscience research translates into treatments. “We’re doing a really shitty job,” he says. “It’s not because we’re not trying; it has to do with the complexity of the problem.”

So he and his colleagues at the renowned institute decided to try a radical solution. Starting this year, any work done there will conform to the principles of the “open-
science” movement—all results and data will be made freely available at the time of publication, for example, and the institute will not pursue patents on any of its discoveries. …

“It’s an experiment; no one has ever done this before,” he says. The intent is that neuroscience research will become more efficient if duplication is reduced and data are shared more widely and earlier. …”

After a year of consultations among the institute’s staff, pretty much everyone—about 70 principal investigators and 600 other scientific faculty and staff—has agreed to take part, Rouleau says. Over the next 6 months, individual units will hash out the details of how each will ensure that its work lives up to guiding principles for openness that the institute has developed. …

Owens’ article provides more information about implementation and issues about sharing. I encourage you to read it in its entirety.

As for getting more research to the patient, there’s a Jan. 26, 2016 Cafe Scientifique talk in Vancouver (my Jan. 22, 2016 ‘Events’ posting; scroll down about 40% of the way) regarding that issue although there’s no hint that the speakers will be discussing ‘open science’.
