Technion researchers have developed a technology that replaces scalpels with natural biological materials.

Researchers at the Technion-Israel Institute of Technology have developed a nanotechnology that replaces the surgical scalpel with an “enzymatic blade.” In an article published recently in ACS Nano, the researchers describe the application of this technology in a surgical procedure in the oral cavity. The application spares the pain associated with orthodontic surgeries and significantly reduces tissue recovery time.

Dr. Assaf Zinger

The study was led by Dr. Assaf Zinger, within the framework of his doctoral research, mentored by Assistant Professor Avi Schroeder, the director of the Laboratory of Targeted Drug Delivery and Personalized Medicine at the Wolfson Faculty of Chemical Engineering. The novel technology is based on rational use of enzymes – biological molecules the body uses to repair itself, as well as on use of nanoparticles for achieving a targeted therapeutic profile.

In the United States alone, approximately five million people undergo orthodontic treatment each year. To speed up treatment, which typically lasts about two years, many undergo invasive surgery, in which collagen fibers that connect the tooth to the underlying bone tissue are cut.

The technology developed at the Technion softens the collagen fibers via the targeted release of collagenase – an enzyme that specifically breaks down collagen. Using techniques developed in Schroeder’s lab, the collagenase is packaged into liposomes – nanometric vesicles. As long as the collagenase particles are packaged in the liposome, they are inactive. But with this special nanotechnology, an ointment is applied on the target site, so that the enzyme begins to gradually leak from the liposome and soften the collagen fibers. The researchers performed a series of tests to determine the collagenase concentration optimal for the procedure and to accelerate tissue repair thereafter.

In a preclinical trial, the researchers compared the efficacy of the controlled-release system (in combination with braces), to that of standard orthodontic treatment and concluded that the system reduces the time required for straightening teeth and improving therapeutic outcome. This would translate to an orthodontic treatment in humans that lasts several months, instead of two years. The researchers estimate that it could be used in humans within a couple of years.

While the ACS Nano article presents a specific application of the “enzymatic blade” in the orthodontics field, the researchers emphasize that the new paradigm can be applied in a variety of surgical procedures. “Over thousands of years, the surgical knife has been upgraded, however, the general paradigm has not changed. Here, in the current study, we present a considerable paradigm shift: replacing the metal blade with a biological process.”

Also taking part in this research collaboration were physicians at the Sourasky Tel Aviv Medical Center Department of Pathology and the Rambam Medical Center Department of Oral Maxillofacial Surgery, and the director of the Moriah Animal Companion Center. The research was supported by grants from the European Council and European Union, German-Israeli Foundation for Scientific Research and Development, various Israeli foundations and Alon and Taub Fellowships.

Universities worldwide are looking to emulate Israel’s tech-transfer magic.

 
By, Abigail Klein Leichman, January 18, 2018. Article published on israel21c.org
 
It’s no coincidence that Harvard and UCLA chose experienced Israelis to direct their technology-transfer offices. Cash-strapped universities urgently need to streamline the transfer of inventions from lab bench to market, and Israeli TTOs have a remarkable track record of generating more revenue from IP sales than any other country except the United States.

“Universities are reinventing themselves as micro environments for innovation and entrepreneurship. A university that can’t demonstrate its impact on industry and the marketplace will become less relevant in the future,” says Benjamin Soffer, chairman of Israel Tech Transfer Network.

Soffer, who frequently hosts TTO officials from top universities in the United States, Europe and the Far East, also heads the Technion-Israel Institute of Technology’s T3 TTO, which encompasses two technology incubators and 90 spinoff companies including ReWalk Robotics and Mazor Robotics.

The Technion’s net research budget of roughly $90 million pales in comparison to MIT’s $1.5 billion, yet its income from commercialisation of research is similar, says Soffer.

“Even more remarkable, the combined research budget of all Israeli universities is half the research budget of MIT. This is validation of the strength of the technology we produce.”

Soffer says Israel’s startup ecosystem provides an efficient “packaging” system for the flood of innovation from universities and military tech units.

“Startups have small teams with tight budgets and schedules and no bureaucracy, so they can be extremely effective. The tech transfer is done through these startups, and big companies don’t mind paying a premium for getting that technology at a later stage when it has been de-risked by the startup.”

Born abroad, raised in Israel

The concept of technology transfer was born at the University of Wisconsin in 1925, later to be nurtured and refined in Israel through the world’s second and third TTOs – the Weizmann Institute of Science’s Yeda Research & Development Company in 1959 and the Hebrew University of Jerusalem’s Yissum Research Development Company in 1964.

According to the most recent Weizmann data, nearly 2,000 patent families have been registered by Yeda and 73 companies were spun off, generating a cumulative $28 billion in sales. Yeda’s first blockbuster deal was licensing multiple sclerosis drug Copaxone to Teva Pharmaceuticals in 1987.

Yissum is Israel’s biggest TTO in terms of patents (10,000- plus), licenses (900) and spinoff companies (125, including standouts such as Mobileye and BriefCam) in a wide variety of fields. In the global seed industry, the long-shelf-life cherry tomato developed at Hebrew University is a primary example.

Some Israeli healthcare organisations also have TTOs.

The nonprofit Israel Tech Transfer Network includes BGN (Ben-Gurion University), BIRAD (Bar-Ilan University), Carmel-Haifa University Economic Corp. (University of Haifa), Gavish Galilee Bioapplications (MIGAL Galilee Research Institute), Hadasit (Hadassah Medical Organisation), Mor Research Applications (Clalit Health Services), Ramot (Tel Aviv University), T3, Tel Aviv Medical Centre, Yeda and Yissum.

Becoming a bridge

Dr. Vladi Dvoyris, director of venture community at Tel Aviv University’s Coller Institute of Venture, says Israeli academic institutions developed a unique way of managing tech transfer.

“Foreign universities usually have two entities, one looking inward for IP worth licensing and one looking outward and liaising with industry. Those two are sometimes not communicating well. The Israeli model has a single point of contact for industry and academic researchers,” Dvoyris tells ISRAEL21c.

When former Yeda and Ramot CEO Isaac Kohlberg was hired to head the Harvard Office of Technology Development in 2005, and when former Yeda CEO Amir Naiberg took the reins at Westwood Technology Transfer UCLA in 2016, they had the opportunity to introduce the integrated Israeli approach, says Dvoyris.

Today’s TTOs must do much more than protect intellectual property (IP), says Yissum’s new CEO, Yaron Daniely. They need to share information among one another and, most importantly build bridges facilitating the free transfer of ideas and opportunities between the academic world and the outside world of entrepreneurs, investors, industries and communities.

“When you’re a bridge and not a knight in shining armour safeguarding the ivory tower, you understand that it’s only helpful when both worlds – academia and industry- benefit. If one world shrinks and dies, the other won’t prosper either,” Daniely tells ISRAEL21c.

“The good TTOs are experimenting with new models to make sure they stay relevant and effective for the benefit of both sides and eventually for the benefit of society,” says Daniely, who holds a PhD from NYU Medical School and an MBA from Technion.

The growth of Jerusalem’s venture ecosystem has contributed to more and bigger deals (think Mobileye, acquired by Intel last March for $15.3 billion). Yissum also has partnerships with the likes of J&J, Novartis, Merck and Google.

Soffer says the volume and speed of deal-making matters more than the terms of the deals. “Technology is all about serendipity and you have to be ready when opportunity presents itself. Most tech-transfer companies in the world are not ready or able to respond quickly. This deal-making approach is unique to Israeli academia.”

And while many university TTOs run entrepreneur clubs, Israeli universities separate the two, encouraging innovation within the university environment even for entrepreneurs planning to retain their IP, says Dvoyris.

HUStart, Hebrew University’s entrepreneurship centre, opened the IP-free zone BioGiv as an “excubator” for this purpose.

Healthcare TTOs 

Tamar Raz, head of Hadasit, the commercialization arm of Hadassah Medical Organisation, was invited to speak at the 2017 annual meeting of the US-based Association of University Technology Managers held in Miami.

“There is very high appreciation for what’s going on in Israel in technology transfer,” she tells ISRAEL21c. “We are considered very advanced both professionally and in terms of the quality of the agreements we do with companies all over the world.”

Founded in 1986 as Israel’s first hospital-based TTO, Hadasit holds fewer patents than, say, the Cleveland Clinic but compares favourably in terms of patents per dollar of research budget, says Raz, who came to Hadasit from Ramot at Tel Aviv University, where she earned a PhD in biology.

“What’s unique is the relevancy of our patents to real medical and pharmaceutical needs because the physicians are familiar with those needs. We also help companies with consulting services from Hadassah physicians,” says Raz.

Like many TTOs, Hadasit is becoming more proactive by “going out and looking for companies willing to advance our inventions.”

In 2006, Hadasit established a public holding company, Hadasit BioHoldings (HBL), enabling investment in its biotech startups through the Tel Aviv Stock Exchange. HBL’s first exit was Cell Cure Neurosciences, in a $12.75 million deal with Biotime in June last year.

“We’re now planning to raise another fund to support early-stage technologies in medical devices and digital health,” says Raz. “This is going on worldwide in TTOs. The big difference is that in the US, most of the investment in university and hospital early-stage technologies comes from philanthropic funds, while in Israel the funding sources are more business-oriented.”

The experts we spoke to believe Israel will continue pioneering the evolving field of bringing innovations from bench to market.

“The startup nation is an example of how Israel has reinvented the way entrepreneurship works, and we are very capable of reinventing technology transfer. Because of the density of our innovation and networking in the world, Israel could be uniquely positioned to lead this transformation,” says Daniely.

Site includes 13 buildings, 29 classrooms, and over 60 laboratories; 3,000 students expected to attend over the next decade.

The Technion-Israel Institute of Technology became the first Israeli university to open a campus in China.

On Monday, the Guangdong Technion Israel Institute of Technology opened in Shantou, in the Guangdong province on the southeast coast. The university is a partnership between the Haifa-based university, the Li Ka Shing Foundation, and the Guangdong provincial and Shantou municipal governments.

The school will offer undergraduate and graduate programs in engineering and science. Some 3,000 students are expected to attend the school in its first decade. The campus includes 13 buildings, 29 classrooms, 14 teaching laboratories and 55 research laboratories.

“[W]e welcome in a new era of cooperative research between Israel and China in science, engineering and the life sciences,” Technion President Peretz Lavie said at the Monday ceremony, according to a statement.

The Shantou institute’s chancellor, Li Jiange, said the China-Israel collaboration was mutually beneficial.

“China offers the Technion a broad platform to realize its academic excellence. We in turn must learn from the Technion and Israel what innovative thinking is,” Jiange said.

In 2013, the Li Ka Shing Foundation donated $130 million to the Israeli university, with some of the money to be used to fund the Guangdong campus. The Guangdong provincial and Shantou municipal governments also contributed $147 million for construction and initial operations, and provided land for the campus.

In September, the Technion, in collaboration with Cornell University, opened a high-tech teaching and research center on New York’s Roosevelt Island.

Seeing a rat scurry by would send many people running away screaming, but researchers at Israel’s Technion institute of technology were joyful when they saw one particular rodent walking.

The rat, once paralysed with a completely severed spinal cord, had weeks earlier undergone pioneering surgery, as part of research headed by Technion and Tel Aviv University.

Professor Shulamit Levenberg, Dean of the Biomedical Engineering Faculty at the Technion, told Reuters: “In this project we managed to induce spinal cord regeneration following complete injury to the spinal cord, and this was to the extent where the animal that was totally paralysed started to walk again and also regained sensory perception.”

Levenberg’s team, together with Professor Daniel Offen’s researchers from Tel Aviv University, used stem cells from an adult human’s mouth and placed them on a sponge-like, biodegradable scaffold, which was transplanted into the site of the rat’s spinal cord injury. This effectively created a pathway circumventing the injured area so that instructions from the brain could reach the rest of the body.

“It was amazing to see the animals starting to walk after 2-3 weeks. They started to walk almost as normal and we were very excited to see this,” she added.

The research was launched following a request from Israel’s Foundation for Spinal Cord Injury in an attempt to tackle the common, yet incurable bodily damage.

In the U.S. alone, some 17,000 patients suffer spinal cord injury each year. Despite rehabilitation protocols and other neuronal transplants, a full recovery of a severed spinal cord has yet to be accomplished in humans.

Levenberg hopes her research will change that, but warns that there is still a long way to go before it reaches the stage of clinical trials in humans.

“These are very early studies and we still don’t know how it will work in humans,” she added.

“This is the big challenge: to treat spinal cord after full transection because we know that spinal cord can not recover by itself,” added Professor Offen, who heads Tel Aviv University’s Neuroscience Lab.

“What we tried to do was to take human stem cells, did some modification and differentiation, and transplanted it with some bio material, some polymer, that was put inside the spinal cord,” he explained.

About 40 percent of the animals that received the treatment regained movement and sensory perception, said Levenberg.

Some regeneration of the spinal cord was seen in the rest of the animals, but not to the extent of full recovery, she added.

The rats were treated shortly after the injury, which allowed the treatment to be effective, Professor Offen estimated. In older injuries, where the part of the spinal cord that was cut off by the injury has had time to atrophy, this solution may not show such positive results.

In the future, he hopes this treatment could be part of every operating room’s basic equipment, allowing doctors to treat spinal injuries as soon as possible.

“Our vision is that in the surgery room there will be frozen cells that once a patient come after full transection of the spinal cord, these cells could be transplanted into the lesion site.”

In an experiment publicised in 2012, paralysed rats were helped to walk involuntarily over obstacles by electrically stimulating the severed part of their spinal cord, in research carried out at Switzerland’s EPFL. Professor Gregoire Courtine’s team announced similar results with monkeys last year.

“This is a badge of honor for Technion,” said Technion President Prof. Peretz Lavie. “In recent years, Technion has placed considerable emphasis on training its students to meet the changing needs of the digital revolution. As a result, Technion’s interdisciplinary research is expanding and advancing by leaps and bounds, in a process integrating life sciences and engineering.”

Lavie said various advanced learning technologies are being implemented at Technion, including MOOCS (massive online open courses) in various languages, as well as a “flipped classroom” approach emphasizing self-study using technologies such as augmented reality.

“In addition, the strengthening of Technion’s global standing, reflected by the Technion branches in New York and China and by strategic partnerships worldwide, helps us attend to the changing needs of global industries,” he added.

The survey’s authors note that global academic institutions are increasingly evaluated according to the employability of their graduates, and that in some places around the world, government support for institutions is linked to graduate success in the labor market.

Aerospace engineers at the Technion-Israel Institute of Technology have developed and patented a process that can be used onboard aircraft while in flight to produce hydrogen from water (including waste water on the plane) and aluminum particles, safely and cheaply. The hydrogen can then be converted into electrical energy for inflight use. The breakthrough could pave the way for less-polluting, more-electric aircraft that replace hydraulic and pneumatic systems typically powered by the main engine.

The groundbreaking work was reported in a recent paper published in the International Journal of Hydrogen Energy.

This technology is expected to drastically reduce the CO2 emissions as well as make the aircraft quieter for those on-board. The system will be able to generate electricity for use on board more efficiently that relying on the main engines.

NanoPack is a Technion led project to introduce nanotechnology-based antimicrobial packaging to enhance food safety and reduce waste that was awarded €7.7 million by the EU as a part of HORIZON 2020, the EU Framework Programme for Research and Innovation.

NanoPack aims to develop and demonstrate state-of-the-art antimicrobial packaging solutions for perishable foods based on natural nanomaterials that will prevent food-borne illness outbreaks and reduce food waste caused by early spoilage.

“NanoPack will demonstrate a solution for extending food shelf life by using novel smart antimicrobial surfaces, applied in active food packaging products,” said Dr. Ester Segal, NanoPack’s coordinator and associate professor at the Technion. “NanoPack will enhance food safety for consumers by significant growth inhibition of food-borne microbes, which in turn will prevent food-borne illness outbreaks and early spoilage.”

EU Awards €7.7 Million to NanoPack Project to Introduce Nanotechnology-Based Antimicrobial Packaging to Enhance Food Safety and Reduce Waste

Brussels, Belgium, January 16, 2017– The European Union (EU) has awarded the international NanoPack consortium €7.7 million to develop and demonstrate a solution for extending food shelf life by using novel antimicrobial surfaces.

The three-year project is aimed at demonstrating, validating and testing food-packaging products with antimicrobial surfaces based upon natural materials. NanoPack will address scientific, technological, economic, safety.

NanoPack, which is led by the Technion – Israel Institute of Technology, is funded as part of HORIZON 2020, the EU Framework Programme for Research and Innovation.

She added that NanoPack would help reduce the staggering 1.3 billion tonnes of food wasted each year, which cause major economic loss and significant harm to the world’s natural resources.

“We intend to present better performing, safer and smarter products that will position Europe as the leader in food nanotechnology and smart antimicrobial packaging while increasing competitiveness and growth,” Dr. Segal added.

The active polymer films developed by NanoPack exhibit broad-spectrum antimicrobial properties unmet by existing state-of-the-art materials, which include currently used nanomaterials such as silver particles, which have raised health concerns of toxicity and microbial resistance.

Applying the power of nanotechnology, the project will employ polymer composites based on natural Halloysite Nanotubes (HNTs) as reliable and safe carriers, capable of tailored release of bioactive payloads. Due to their size, HNTs are unable to migrate from the food packaging into food. Maximizing safety, HNTs in the NanoPack food packaging slowly release

minute amounts of potent, volatile, natural and EU-approved essential oils into the packaging headspace. The oils exhibit both antimicrobial and anti-fungal properties and can be tailored to inhibit growth of most food-borne microbes.

The NanoPack consortium is comprised of 18 partner organizations – leading industrial and research institutes – from Belgium, Austria, Norway, Spain, Israel, Ireland, Denmark, Portugal, France, Germany and the Netherlands.

NanoPack project concept

NanoPack will hold its opening conference at the facilities of Bio Base Europe (BBEU) in Ghent, Belgium on January 24–26, 2017.

About NanoPack

NanoPack is an EU-funded project, which aims to develop and demonstrate a solution for extending food shelf life by using novel antimicrobial surfaces applied in active food packaging products.

NanoPack intends to develop, scale up and run pilot lines in operational industrial environments to manufacture and validate antimicrobial polymer films that are commercially feasible and accepted by retailers and consumers alike.

Researchers at the Technion Viterbi Faculty of Electrical Engineering have developed a device that can diagnose neurological disease by tracking eyelid motion. The eyelid motion monitor technology (EMM) was tested on 100 healthy subjects to collect a base line of blinking patterns. This was then used to diagnose individuals with blepharospasm dystonia, a disease characterised by involuntary contraction of the muscles responsible for closing the eyes.

The hope is that this technology will be used in regular eye tests to diagnose all diseases that a expressed neurologically. The researchers are testing the technology in the diagnosis of dementia and Parkinson’s and hope to develop to cover Thyroid eye disease, Ptosis and other cranial nerve palsy.

What Do Your Eyes Say? Device Can Diagnose Diseases Based on Eyelid Motion

HAIFA, ISRAEL (October 15, 2017) – Researchers at the Technion-Israel Institute of Technology Viterbi Faculty of Electrical Engineering have developed a device that can diagnose diseases by means of an eyelid motion monitor (EMM). The project was published recently in Graefe’s Archive for Clinical and Experimental Ophthalmology.

Already in its developmental stages, the device has won several international awards, and was ranked in the top 20 in the Texas Instruments Innovation Challenge (TIIC) – Europe Design Contest. Over the past two years, the device has been used in clinical trials at Haemek Medical Center in Afula, Israel.

The device was first developed by Technion Prof. Levi Schachter and doctoral student Adi Hanuka, who began working on it as an undergraduate. Hanuka continued working on it during her graduate studies, with the help of a team of students working under her supervision.

“Eyelid motion provides us with meaningful information about the health of a patient,” explained Hanuka. “This motion can indicate not only eye diseases, but also neurological diseases such as Parkinson’s, and autoimmune diseases such as Grave’s. We developed a device that can be installed on the standard refraction glasses used in eye tests, at the request of Dr. Daniel Briscoe, Chairman of the Haemek Medical Center Department of Ophthalmology.”

Glasses are fitted with a hardware and software system that monitors and interprets eyelid movements. With approval of the Ethics Committee Regulations for Research Work Involving Human Participants, measurements of approximately 100 subjects have been collected in order to define the eyelid motion patterns (blinking speed and frequency) of a healthy person. Eyelid motions were analyzed using a signal-processing algorithm written by students Tal Berkowitz, Michal Spector, Shir Laufer, and Naama Pearl.

The team first examined blepharospasm dystonia, a disease characterized by involuntary contraction of the muscles responsible for closing the eyes. The researchers found a statistically significant quantitative relationship between a person’s eyelid pattern and the disease, which means that the device could be used to diagnose it. The system was also used to examine the effect of Botox injections, the conventional treatment for the disease, and it was found that within 15 minutes contractions decrease and the blinking pattern begins to match indices that exist among healthy people.

The researchers are also gathering information about other groups, including patients with dementia and Parkinson’s disease.

“Along with designing the product for purposes of commercialization, we are working in several directions: developing the device as a platform for multidisciplinary research on various topics such as the effect of emotions on blinking patterns; eyelid communication amongst the paralyzed; and automatic diagnosis through machine learning and based on a computerized comparison between the specific monitoring and an extensive database,” said Hanuka.

According to the researchers, the device has the potential to diagnose every disease that is expressed neurologically, including many ocular and systemic such as Ptosis, Thyroid eye disease, Parkinson’s disease, Myasthenia Gravis, and neurologic diseases such as third and seventh cranial nerve palsy.
