Other leukaemia sufferers as well as cancer patients in general are also expected to benefit in the long term.

The challenge: if conventional speaking valves are used improperly, dangerous overpressure can occur, which can cause serious complications and even death. In a collaboration at the University of Freiburg, researchers developed a speaking valve with an integrated pressure release valve and an acoustic warning signal, inspired by the trapping mechanism of the carnivorous bladderwort plant Utricularia vulgaris.

Cancer immunotherapies often fail because the immune cells are paralysed by immunosuppressive conditions in the tumor. Scientists from Heidelberg, Mannheim and Tel Aviv have now shown on tissue samples from patients as well as on tumor models in mice that the functionality of the immune defence depends decisively on certain helper cells.

The progression of multiple sclerosis (MS) can usually be slowed down with medication, but a cure is currently not possible.

Tracking down tumour-associated pain in pancreatic cancer

Pancreatic cancer comes along quietly: unnoticed for a long time, it often triggers excruciating pain as the tumour progresses. This pain is associated with cancer cells invading pancreatic nerves. Dr. Michael Hirth from Mannheim University Hospital has shed some light on the complex communication between cancer cells and nerve cells. His findings could eventually be used for personalised pain therapies.

A team of engineers and biotechnologists at the University of Freiburg has for the first time shown in mammals that the concentration of antibiotics in the body can be determined using breath samples. The breath measurements also corresponded to the antibiotic concentrations in the blood. The team’s biosensor – a multiplex chip – will in future enable personalized dosing of medicines against infectious diseases on-site.

The hospital pathogen Pseudomonas aeruginosa requires the sugar-binding proteins LecA and LecB to form biofilms as well as to attach to and penetrate host cells. These so-called lectins are therefore suitable targets for active substances to combat Pseudomonas infections. Researchers from Saarbrücken and Freiburg have now produced potent inhibitors for LecA and LecB that are more stable and soluble than previous drug candidates.

Professor Claudia Denkinger from Heidelberg University's Faculty of Medicine is leading the international collaborative project "BreathForDiagnosis". Researchers from Germany, Italy, South Africa and Romania are working with an industrial partner from Switzerland to develop user-friendly breath tests for the rapid diagnosis of respiratory infections such as tuberculosis.

Certain developmental signals play a significant role in maintaining our genetic blueprints. They prevent alterations in the genome, known as mosaicism. The underlying biological mechanism helps the DNA to produce an identical copy of itself during cell division using the original genetic blueprint. However, it can also contribute to genomic mosaicism during nerve cell development.

Toxicologists from the University of Konstanz have found that the protein p53 continuously protects our cells from tumorigenesis by coordinating important metabolic processes that stabilize their genomes.

Brain tumour patients could benefit from heavy ion therapy

Glioblastoma is a malignant brain tumour. It does not respond anywhere near as well to conventional forms of therapy than other tumours because it contains particularly resistant cancer cells. Scientists at the Heidelberg Ion Beam Therapy Center (HIT) at Heidelberg University Hospital and the German Cancer Research Center have shown that heavy ion therapy is effective against these cells.

In the field of optogenetics, scientists investigate the activity of neurons in the brain using light.

Epifadin from the nasal microbiome - 28/03/2024

From the nose: novel antibiotic substance discovered

Antibiotics are becoming an increasingly blunt weapon against infectious diseases. The number of (multi-)resistant germs has been rising rapidly for years and even reserve antibiotics no longer work. Researchers at the University of Tübingen have now isolated a completely new antibiotic substance called epifadin from the microbiome of the human nose. It is effective against many different bacteria - including the dangerous hospital MRSA.

App for tuberculosis diagnosis - 15/05/2024

"Find-TB" aims to improve access to tuberculosis diagnostics

Globally, the majority of children with tuberculosis remain undiagnosed and therefore untreated because their symptoms are categorised incorrectly. Researchers at Heidelberg University Hospital want to develop an app that analyses medical information, risk factors and local surveillance data to calculate individual risk of infection and test those who might be affected with TB as early as possible.
