guidoo: robotic assistance for fast and precise biopsies

Needle-based procedures through the skin, such as biopsies of internal organs, not only require a great deal of skill and experience, but they also take time. Fraunhofer IPA Mannheim, together with BEC GmbH from Pfullingen, is developing a robotic surgical assistance system that supports the correct positioning and angulation of a needle with the help of a guide sleeve. This significantly speeds up the procedure while maintaining precision.

Elastin as artificial muscle material - 02/03/2022

Artificial muscle from proteins for diverse future applications

As far as diversity and complexity are concerned, proteins are nature's smallest marvels. Biotechnologists have already used natural proteins as a basis for the development, bespoke design and production of artificial systems. This is what the livMatS cluster of excellence at the University of Freiburg has been doing. Researchers in the cluster have successfully produced an artificial muscle from elastin that functions autonomously.

Researchers use epigenetic factors to investigate the role of stress in the development of tumor diseases. Experts believe that stress plays a major role in the development of tumors. One occupational group, for example, that experiences extreme stress over a short period of time is astronauts.

Dr. Stefan Schiller and Dr. Matthias Huber from the University of Freiburg’s livMatS Cluster of Excellence have succeeded in developing a muscle solely on the basis of natural proteins. The autonomous contractions of the material, which the researchers presented in the journal Advanced Intelligent Systems, can be controlled with the help of pH and temperature changes.

Advanced therapy medicinal products: gene and cell therapies

Novel gene and cell therapies for treating incurable and hereditary diseases have raised high expectations. However, success has so far been limited to the long-established bone marrow transplants involving the administration of haematopoietic stem cells used to treat blood cancer. CAR T-cell therapies have recently emerged as a major new hope in cancer treatment.

Furtwangen University publishes the world’s first molecular biological study on bacterial contamination of slit lamps. Slit lamps are among the most important tools used by ophthalmologists and opticians. They allow selected areas of the eye to be magnified and examined for diseases.

Dermagnostix develops molecular diagnostic tests for skin diseases

Dermagnostix GmbH has developed a rapid test to differentiate between psoriasis and eczema. This test is currently undergoing preclinical testing, with market launch planned for 2023. The start-up is already working on two other dermatological tests. Centrifugal microfluidics is the name of the technology on which the tests are based.

The mechanisms by which the body measures temperature and regulates its own body heat are vital, but still poorly understood. The discovery of the first heat sensor on nerve cells in the skin, for which the U.S. molecular biologist David Julius received this year's Nobel Prize for Medicine, was therefore pioneering.

The many faces of the epigenetic regulator MOF

Epigenetic modifications play a crucial role in coordinated gene transcription, and are required for a fertilised egg cell to be able to develop into an organism with different cell types. Dr. Asifa Akhtar from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg has been studying the essential epigenetic regulator protein MOF for 20 years.

The bacterium Staphylococcus epidermidisis primarily a harmless microbe found on the skin and in the noses of humans. Yet some strains of this species can cause infections – in catheters, artificial joints, heart valves, and in the bloodstream – which are difficult to treat. These bacteria are often resistant to a particularly effective antibiotic, methicillin, and are among the most feared germs in hospitals.

Calling for quality seal for implants

Today's seniors are older and more active, which is why implants remain in the body longer and are subjected to greater strain than before. Improved surfaces are expected to ensure that the implants heal and integrate into the bone optimally. In an interview with BIOPRO, Dietmar Schaffarczyk, CEO of Konstanz-based stimOS GmbH, explains why a voluntary quality seal makes sense and gives consumers a better chance of recognising high-quality…

Gene accordions as potential markers for pathogenic properties

Bacteria must react to changes in the environment in order to survive. This is partly done by adapting genetic material, for example by multiplying and shortening individual genome segments. The research group led by Dr. Simon Heilbronner from the Interfaculty Institute of Microbiology and Infection Medicine at the University of Tübingen has shown that these so-called gene accordions are frequently found in the bacterium Staphylococcus aureus.

New method for analysing blood samples - 26/11/2020

Personalised therapy monitoring for malignant melanomas

Immunotherapy has greatly improved the survival chances of patients with malignant melanoma. A study has now begun at the Department of Dermatology at the University Hospital of Tübingen to develop a way to monitor the course of treatment as effectively as possible. It involves personalised monitoring using liquid biopsies in addition to conventional PET/CT examinations. This analysis procedure of blood samples could enable closer monitoring of…

Neglected tropical diseases - Gisela Schneider: the burden of disease

"Leaving no one behind". The motto of the 2030 Agenda with its 17 Sustainable Development Goals (SDGs) which was signed by the United Nations (UN) in 2015 makes clear that combatting poverty and its consequences is an essential part of sustainable development. The fight against neglected tropical diseases (NTDs) is defined as a major aim of the Agenda’s sustainable development goals. The World Health Organisation (WHO) regards twenty…

RNA interference confidence is returning

The 15-year history of RNA interference is not short on dramatic effects. It begins with the unexpected discovery and publication of the process of post-transcriptional gene silencing in 1998 for which Andrew Fire and Craig Mello were awarded the Nobel Prize in Physiology or Medicine just eight years after their discovery. In 2001 Thomas Tuschl succeeded in switching off genes in human cells with small synthetic pieces of RNA siRNA.

Adult stem cells hope for regenerative therapies

Adult stem cells have the lifelong ability to generate new specialised cells. They secure the continuous replenishment of cells therefore enabling the constant replacement of dying cells with new ones. Progress in the characterisation isolation and specific differentiation of adult stem cells over recent years raises hopes for the future use of the cells in the therapy of degenerative diseases. Knowledge about adult stem cells also has the…

New trends in the field of immunology

B- and T- lymphocytes along with macrophages have long been regarded as the most important cells of the human immune system and have been a major focus of research. This has now changed and it is now the dendritic cells that are regarded as the major components of the adaptive immune system. Research into innate immune defence mechanisms has become more important due to the discovery of the role of Toll-like receptors as first-line of defence.
