Brandenburg’s contributions to medicine

Medical research has not been confined to the clinic for a long time. That is why Brandenburg’s decision to do without its own medical faculty does not mean that it is abandoning this seminal branch of research. Medicine at the highest level is inconceivable without intelligent, well-engineered materials and new discoveries at the cellular and molecular level. All of this is being driven forward with vigour and great success at the Potsdam-Golm Science Park, as witnessed by the many prizes and awards its researchers have received. The first page of this PS edition only has room to present a few of the many highlights.

Soon young parents will be able to carry out their research unencumbered by worries over child care and largely free from time constraints. The new Fröbel day-care centre will set a milestone in the compatibility between family life and work, and add a new quality of life dimension to the research location.

Enthusiasm for their own subject and a high level of commitment are the hallmarks of the working groups exhibiting at the open day that was held at the institutes and the children’s university with numerous demonstrations and experiments. Visitors both tall and small were equally fascinated – and we can well imagine some future career plans were laid there too.

But even with the best working conditions and high motivation we still need a break, and so I wish you relaxing holidays and a good beginning to the New Year.

Future antibiotics from tobacco?

Potential to grow proteins with antibiotic properties in tobacco plants.

At first glance, the combination of tobacco and medicine seems as unlikely as fire and water. Hitherto tobacco has been linked to health-damaging and carcinogenic attributes, but recently scientists have begun using tobacco plants to produce highly effective drugs. Tobacco is an especially suitable plant for this type of production, as it produces a lot of leafy material in a very short time and is also not used as a food.

The chloroplasts in tobacco plants, the location of photosynthesis, when genetically modified can produce large quantities of antibiotic-acting proteins, as was demonstrated in earlier work by the working group led by Professor Ralph Bock at the Max-Planck Institute of Molecular Plant Physiology. Special viruses (bacteriophages) attack bacteria, reprogramme their genetic material in order to multiply themselves and then dissolve the bacterium in order to be released.
These proteins coded by the bacteriophage, which lead to the death of the bacterium (antibiotic effect), are called lysins.

In order to obtain a high yield from these antibiotic-acting proteins in the plant after the backdoor recruitment of the bacteriophage gene, the gene must first be prepared in the laboratory bacterium Escherichia coli by molecular genetic methods in order to ensure efficient protein production in the chloroplast. However, the gene already here, i.e. before its transfer to the chloroplasts, must be prevented from being converted into protein, as otherwise the laboratory bacterium would be killed immediately.

Ralph Bock and his team have found a method that makes it possible to make the gene functional for forming the lysins only after transfer to the chloroplast. This newly developed strategy relies on a difference in the way that genetic information is read between chloroplasts and bacteria. In the bacterium, certain gene sequences (terminators) are used to mark the end of a gene and so end the reading process (transcription) of the DNA, which leads to the formation of a messenger RNA (mRNA). These terminators are effectively “skipped” when read in chloroplasts. In order to prevent the toxic gene products (antibiotic-acting proteins) from forming too early, the scientists used terminators that act to end the reading process in the bacterium prematurely. However, because the information in the chloroplasts is read in full, the synthesis of the lysin antibiotic can proceed there unhindered. With a further molecular trick, once the new gene has been successfully introduced into the genome of the chloroplasts, the terminators, now no longer needed, are removed, so that at the end only the lysin genes remain as new genetic information in the chloroplast. “The effectiveness of the lysins produced in the chloroplasts was convincingly demonstrated in tests on bacteria cultures of Streptococcus pneumoniae, which is the pathogen that causes pneumonia,” explains Dr Bernd Kreikemeyer of the Institute for Medical Microbiology, Virology and Hygiene at the University of Rostock. Even small quantities of the lysins were shown to be highly effective. The proportion of lysin to total protein in the tobacco plants was as much as 30 per cent.

“The antibacterial proteins obtained from plants for therapeutic use are safer than proteins obtained directly from virus-infected bacteria. What's more, no further cleaning steps are required to remove the damaging bacterial endotoxins,” says Professor Ralph Bock, highlighting the benefits of antibiotic production in plants.

In the case of tobacco, the genetic modification of the chloroplasts is killing two birds with one stone: the antibiotic production is very high, as each plant cell has a large number of chloroplasts, and the modified genetic information is barely passed on at all in the plant’s pollen, which increases the plants’ biological safety.

Into the cell with the micro-shuttle

Microcapsules release substances in cells “on command”.

Scientists at the Max Planck Institute of Colloids and Interfaces in Potsdam-Golm, the Jacobs University of Bremen and the Queen Mary University of London have succeeded for the first time in introducing microcapsules into living cells without damaging them and in releasing their contents with a laser pulse at a precisely controlled time. With this method the researchers have managed to describe immune processes in the cell’s interior for the first time, from the release of foreign proteins within the cell to their incorporation on the cell surface. Reactions of the organism such as the immune response to virus infections can only be understood if the transport and conversion steps of the substances involved can be followed in exact chronological order. Often this is done using marker molecules whose fate can then be traced in the cells using different detection methods. However, many of these methods have one decisive drawback: the molecular markers cannot be introduced into the living cells in sufficient quantity. Then again, other preparation methods with higher reagent concentrations impair the cell functions and thus the normal course of the processes being examined.

The aim of the research cooperation was therefore to prepare living cells with as little damage as possible and with defined quantities of experimental markers and then to release them inside the cells in a controlled fashion and at a defined point in time. This should however only occur after the cells have recovered from the negative effects of preparation.

To introduce the substance, the researchers developed “miniature shuttles” from special metabolic-resistant plastic fibres with incorporated nanogold particles. The micro-transporters are about as large as a small bacterium, with a diameter of around two micrometres. The microcapsules were made by wrapping the plastic fibres around a mineral core like a net, which is then dissolved using acid. The porous micro-hollow spheres this produces can then absorb the released test substance and are then easily sealed by heating.

The filled capsules are then diffused through the cell walls, which have previously been made permeable to particles of this size using electroporation, a type of electric shock treatment. To release the test substance inside the cell, the cells are then shot at with an infrared laser, which does not damage the cells, but which is absorbed by the nanogold particles in the capsule walls. The “shuttles” heat up, and the capsule walls melt.

The scientists have already proved that this method works. They introduced microcapsules with artificial, fluorescent-marked protein fragments into liquid-cultivated, living rodent cells. After releasing these markers with the laser pulse, the researchers were able to observe the dispersion of the foreign peptide markers in the cell, their take-up by protein components of the immune system, the MHC proteins, and their transport to the cell surface and incorporation there as antigens in high time resolution under the fluorescent microscope.
“When you think that infrared light can penetrate tissue to a depth of one centimetre, and that in medicine optical fibres are being used for diagnosis and therapy in ever more refined ways, the idea of a light-induced release of a substance into the tissue is no longer utopian,” says Helmuth Möhwald, director of the department of interfaces at the Max Planck Institute of Colloids and Interfaces. However, a development of this type still needs many years of basic and applied research.(Image) Micro-shuttles (orange) inside two cells (green), taken with a confocal microscope.

Eyesight thanks to artificial cornea

Development by the Fraunhofer Institute for Applied Polymer Research is in clinical trials

The artificial cornea developed by Fraunhofer researchThe artificial cornea developed by Fraunhofer research scientist Dr Joachim Storsberg and his team in cooperation with doctors at the Halle and Regensburg University Eye Clinic has been successfully implanted in a patient for the very first time. “His sight is definitely better than before,” reports Storsberg.

The cornea, the crystal-clear, curved front part of the outer layer of the eye is the “window to the eye ball” and plays a major part in refracting light for image focusing. The cornea is kept moist with tear fluid, which not only provides it with nutrients, but also protects it against infections and reduces the friction caused by blinking. This involves some complex interactions between the surface of the cornea and the tear fluid.

However, mechanical accidents and chemical burns, inflammations and diseases such as infection with the herpes virus as well as genetic malformations can damage the cornea so badly that without the transplant of a new cornea patients would go blind. In this operation the central part of the damaged cornea is removed and replaced with a graft. Because the cornea is not supplied with nutrients via the bloodstream, but from the tear fluid, the risk of rejection is low, even in the case of donor corneas. However, according to Storsberg, every year there are around 7,000 people waiting for a donor cornea in Germany alone, which is why the artificial cornea offers a real alternative.

The standards for this type of prosthesis are high, since it has to fulfil a number of opposing tasks on a very small surface. For this the scientist developed a prosthesis based on a water-repellent polymer that adheres to the natural cornea of the eye. “The edge of the disc that has to be incorporated was covered with active polymers to make it stick,” explains Storsberg. A special, ultra-thin layer of hydrogel, which is polymerised into the front optical area, ensures on the other hand that no cells can stray into the centre of the prosthesis, to keep the field of vision clear. The tear film and also medicaments are effective in keeping it moist, and the eyelid does not perceive the implant as a foreign body. In addition, the whole mini-prosthesis has to be thermally stable in order to survive the sterilisation process.

The cornea is the outcome of the EU-funded “Cornea” research project, in which several institutions have been collaborating since 2005. “Provided further tests prove successful, we hope the product will be on the market by the middle of 2010,” says project spokesman Georg Langstrof.

Prizes, Awards and Medals

The format of the Potsdam Science Park is growing not only in size but in substance too. Numerous accolades of various kinds have been received by the park’s researchers, postgraduates, students and start-up businesses over the last six months. The icing on the cake was the prize of the Stifterverband für die Deutsche Wissenschaft for “Excellence in Teaching” awarded to the whole university. The lecturers are qualified for a skills-oriented and research-based teaching profession in target group-specific qualification courses for junior teaching professionals, post-docs and senior teaching professionals. To establish their effectiveness and the developing skills of the students, a longitudinal section of study biographies was monitored in an online student panel. Prize money: 1 million euros.

The Macro Group UK Medal for Outstanding Achievement 2008 of the Royal Society of Chemistry was awarded to Professor Markus Antonietti, Director at the Max Planck Institute of Colloids and Interfaces. This medal is awarded to an outstanding international scientist in the field of large molecule research.

The Tetrahedron Young Investigator Award 2010 for Bioorganic and Medicinal Chemistry was awarded to Professor Peter H. Seeberger, Director at the Max Planck Institute of Colloids and Interfaces. Seeberger is rewarded for his research into biologically relevant carbohydrates and their role in the molecular recognition of cell interfaces and thereby infections and immune reactions.

The Potsdam quantum physicist Prof. Dr. Jens Eisert became a fellow of the Berlin Institute of Advanced Study. Around 40 fellows from different countries and scientific disciplines form a research community at the college for a set period which promotes intellectual and intercultural exchange beyond their own specialist field.

The honorary title of “Culture Manager of the Year 2009” was bestowed on Folkert Uhde, head of the Berlin RADIALSYSTEM space for the arts in Berlin and also lecturer at the Institute of Music. The jury praised Uhde’s ability to “create new formats which link different categories and genres in a principle of dialogue”.

The “Women in Science” prize went to Dr. Margarita Staykova, a biophysicist at the Max-Planck Institute of Colloids and Interfaces. The prize, which is worth €20,000, is awarded by Unesco, the L’Oréal cosmetics group and the Christiane Nüssland Vollhard Foundation and is directed at outstandingly qualified postgraduates with children working in Germany in the experimental sciences and is designed to enable them to avoid breaks in their career when starting a family.

The BIOTECHNICA studies prize was awarded to a thesis produced at Golm: Ulrike Glaubitz of the Max Planck Institute of Molecular Plant Physiology took third place in the prize awarded by the VBIO, the central association for biology, biosciences and biomedicine in Germany. The prize is endowed with a total of 5,000 euros and is sponsored by Roche.

Second place in the “photonics21” competition for the “Student Innovation Award” was won by Andreas Jechow. The doctoral student at the Institute of Physics and Astronomy at the Hochschule Potsdam was rewarded for his paper on “Licht aus Breitstreifenlasern in externen Resonatoren – Erschließung neuer Anwendungen”, which he wrote as part of his dissertation.

The team at Signavio GmbH was awarded the first prize endowed with 25,000 euros at IFA, the world’s leading consumer electronics event in Berlin. It was presented by Dagmar Wöhrl, Parliamentary Secretary of State at the Federal Ministry of Economics and Technology. Together with Signavio GmbH the GO-Incubator team was happy about the prize, as they had helped the winners in the start-up phase.

Highest award of the German Colloid Society
for Helmuth Möhwald

The world’s oldest association in the field of pure and applied colloid science, the German Colloid Society, has honoured Professor Helmuth Möhwald with the Wolfgang Ostwald Prize.

Helmuth MöhwaldThe famous award honours the extensive, wide-ranging lifetime achievement of the oldest founding director at the Max Planck Institute of Colloids and Interfaces. It celebrates Helmuth Möhwald’s leading position in international research and his great service to science. His research has ranged from studying the organisation of molecules in monolayers on fluid interfaces, through the formation of organised organic layers and their function, through to the production of functional microcapsules and their application. Recent scientific work is concentrating on self-repairing coatings. Thereby special nanocontainers made of polymers make sure, that active agents will be released at arising damages and repair them instantly. On top of that the substances can be released as needed. Furthermore the remote-controlled release of drugs is a central theme. Obviously drugs help most if they are able to get directly to the diseased organs or cells such as tumor cells. But also the field of sonochemistry which deals with the effects of ultrasonic on chemical systems is one of the latest research topics. Helmuth Möhwald has published more than 750 peer-reviewed publications and his work has been quoted more than 25,000 times. He is also a highly successful university lecturer: More than 60 former colleagues now occupy professorial chairs in Germany and abroad, in the areas of physical chemistry, applied physics and biophysics, polymer chemistry, material sciences and chemical engineering.

The German Colloid Society honors outstanding scientific research in the area of pure or applied colloid science by the Wolfgang Ostwald Prize. The scientific life-performance of outstanding experts should primarily be appreciated by this award. The price consists of a document and a memorial-coin.

Remembered: Wolfgang Ostwald

Wolfgang Ostwald (1883-1943) is known as the founder of colloid chemistry in Germany.

Wolfgang OstwaldStudies in natural sciences where he specialised in biology (doctorate 1904, Habilitation 1907) were followed by his first work on colloid chemistry at the University of California, Berkeley (1904-1906). Back in Leipzig he introduced this subject there – he edited the Zeitschrift für Chemie der Kolloide (later the Zeitschrift für Kolloidchemie, then Colloid and Polymer Science), founded the Kolloidchemische Beihefte and gave many international lectures in London, the USA and Canada. After two years’ military service during the war he qualified a second time with a doctorate in “his” subject of colloid chemistry. In 1922 he was appointed Professor of Colloid Chemistry at the Institute of Physics and Chemistry at the University of Leipzig, and was made a full professor in 1935. On his appointment in 1922 Wolfgang Ostwald founded the German Colloid Society and became its first president, a position he held until his death.

The best for children

Ground-breaking ceremony for the new day-care centre on the Potsdam Science Park

Excited and perfectly kitted out in lab coats and home-made “protective goggles”, 60 small children waited for their big moment after the official speeches at the ground-breaking ceremony of the science park's new day-care centre.

By August 2010, a day-care centre with 120 places, 60 of them for children under three, will be built in the midst of the university and the research institutes. “Under agreed cooperations, some of these places are reserved for the staff working at the institutes and companies on the science park, although the centre will also be open to students and young families living nearby,” stresses site manager Friedrich Winskowski. This project has been under consideration since 2007, and arose in a cooperation between the Fraunhofer and Max Planck Institutes based here, the University and the City of Potsdam. The idea was taken up by the science park's new site management and quickly led to this concrete result. After completion of the infrastructure with the railway underpass, the building of the new business centre and the setting up of a site management team, it will add a further plus factor to this location, says Potsdam’s mayor Jann Jakobs: “I am delighted that the Potsdam-Golm Science Park will be even more attractive to German and international researchers once we have the new kindergarten. Because a strong location also strengthens the region.” Research work often involves irregular hours, so it's a great relief to young parents to know that their children will be looked after even outside normal hours. The day-care centre operator, the association Fröbel e.V., offers flexible opening hours up to at least eight o'clock in the evening. And the new day-care centre will even stay open during the summer holidays. The provision of bilingual education by English native speakers will not only meet the needs of the large number of foreign scientists, but will also use the educational knowledge that children pick up foreign languages particularly easily at this age. The Biotop next to the site plays to the operator’s concept of bringing up children close to nature, with environmental education and nature preservation. Nourished with high quality, freshly prepared food, here the children will be able to carry out their own early research projects no matter what the weather. “The best for children and all the help we can give to parents,” is how Rainer Borgmann-Quade, chairman of Fröbel e.V. describes the association's aims, “this will give parents maximum planning certainty, which is an important condition for a proper work-life balance.”

At last the “small researchers” were able to get on with the children’s experiments prepared for them by the Fraunhofer Institute for Applied Polymer Research and the Max Planck Institutes of Colloids and Interfaces and Molecular Plant Physiology. The lab coats may well have been clean thus far, but by the time the spaghetti and tomato sauce had been eaten, they had proved their worth as protective clothing!

An exhibition of the background and aims of the Fröbel teaching method is open from 8 am to 6 pm on the ground floor of the GO:IN building.

New application centre for polymer nanotechnologies

application centre for polymer nanotechnologiesThe delivery of the funding decision by the Brandenburg Investment Bank (ILB) to the head of the Fraunhofer Institute for Applied Polymer Research (IAP), Prof. Dr. Hans-Peter Fink, gave the go-ahead to the building of the new application centre for polymer nanotechnologies for the Fraunhofer IAP. The task of the new application centre will be not only to transfer innovative materials and technologies from the laboratory scale to the industrial production scale, but above all to further develop the technological bases for the production of plastics-based, flexible displays. Here the centre will work intensively with the Bundesdruckerei Group in Berlin in the joint SecurityLab. It has also recently signed a memorandum of understanding with the renowned Korean Electronics Technology Institute (KETI) with a view to preparing extensive project activities. A second focus will be on biopolymers, where the application centre will develop new biotechnology procedures and products in a pilot facility scale.

The new building is the result of an architectural competition and will extend the current Fraunhofer IAP in an L-shaped annex. It will provide around 2600 m2 of extra floor space, some 1400 m2 of which will be for laboratories and technical facilities and a further 1050 m2 for offices. The application centre will create space for some 100 new members of staff, which will enable the institute to expand by around 50 per cent compared to its current size.

Magic ink and earthworms

Impressions of the Open Day at the Potsdam-Golm Science Park

It was that time again, as the institutes of the Potsdam-Golm Science Park opened their doors on 19 September, and more than 2,000 visitors arrived to experience science as something they could touch and join in with. It was not only the children who had a good time, there were many things for the adults to enjoy too.

Numerous tours, experiments, talks and presentations awaited listeners and participants of all ages with a love of science.

In the molecular kitchen, seven-year old Paula looks on in amazement as the fruity yellow milk product is frozen into a delicious ice in a matter of seconds. On the nearby experiments stand, teenagers brood over mathematical puzzles, while on the next stand glue is being made from plant starch. The aroma of freshly baked bread and waffles fills the hall, as the children learn how to make flour from grain and what the difference is between wholemeal and white flour.

Anyone who didn’t know that earthworms have a sense of smell, despite having no nose, found out on the University of Potsdam’s stand, and that even earthworms have all their wits about them. Not only at the three Max Planck institutes but also on the campus of the Fraunhofer institutes children were deciphering secret messages with magic ink, investigating the secret of liquids, or being taken back to life in Ancient Egypt.

Colleagues from two Fraunhofer institutes, three Max Planck institutes, the GO:IN innovation centre and the University of Potsdam took the visitors on a tour through space and time, showing them monster masses in space, and giving them an insight into the micro-cosmos of bacteria, fungi, algae and plants. The Fraunhofer truck presented the latest research and innovations from the Fraunhofer institutes, including intelligent clothes, a new type of Mp3D player, a camera you can swallow, decentralised water management, and lots more.

Many politicians from the Landtag and Kreistag along with city councillors were invited to the Open Day by the institutes, so that they could learn for themselves about the latest research projects and see the developing infrastructure, including the planned supermarket, a new student hall of residence and the improvements to the rail connection.

On 25 September 2009, the university campus in Golm belonged to children. On this day 1,800 third- and fourth-year pupils from Potsdam and the surrounding area came to the 6th Potsdam “Children’s University”. In lectures prepared especially for them the children learned how language comes into your head, why Einstein imagined riding on a beam of light, how your eyes move when you read and why bats sleep upside down. The scientists had adapted to their young audience by creating clear examples and child-friendly experiments. Just like proper students the small visitors were able to sniff the university air in eleven different lectures. And at the end there was food in the canteen.

Impressions of the Children’s University can be found at www.kinder.uni-potsdam.de.


First GO:INcubator Venture Forum

Ground-breaking ceremony for the new day-care centre on the Potsdam Science Park

The first GO:INcubator Venture Forum was held on 14 October 2009 at the Villa Arnim in Potsdam. The guests were treated to presentations of the business ideas of five EXIST-funded start-up teams from innovative technology groups. The aspiring entrepreneurs seized their opportunity at the Villa Arnim, the headquarters of the Industrieclub Potsdam, near the entrance to the Sanssouci Park, to exchange ideas with potential investors and make contact with business financiers.

“The GO:INcubator Venture Forum is an outstanding addition to our monthly Hightech-Starter Lounge,” says Thomas von Gizycki, head of the BIEM CEIP GO:INcubator project. Whereas the lounge is used to discuss possible ideas for new businesses, and as a networking opportunity for business founders from the Hochschule, the Venture Forum is designed to give young teams easier access to venture capital. The Venture Forum is expected to be held once a year, whereas the Hightech-Starter Lounge takes place every month.

Benefit concert given by the music students in aid of the ProSoYa project on 16/12/09, at 19:00 at the Golm Kaiser-Friedrich-Kirche

Benefit concertProSoYa - Proyecto Social on the river Yanachaga is a non-governmental aid organisation in the Peruvian rainforest which provides education and training for 50 children and young people. The general situation in Peru is characterised by extreme poverty, malnutrition, a high child death rate, a shortage of medical care as well as inadequate education and training. ProSoYa wants to combat this by offering help to poor and often abandoned children.

After they have finished school they receive recognised training at one of the project’s various workshops, which will enable them to find a good job. Help for self-help. The graduates have found the route out of poverty! Since 2006 ProSoYa has been expanding, above all so that it can include girls, since women have very low status in Peru. This year we supported this expansion by building a new house which has a provided living accommodation for 12 girls. Next year we want to continue this expansion, which is why we are asking for donations.
