3D imaging technique reveals pancreatic cancers start

05/02/2019

A new technique to study tissue samples in 3D has revealed that pancreatic cancers can start and grow in two distinct ways, solving a decades-old mystery of how tumours form. The new method could help researchers to get more information from tissue biopsies and may lead to improved treatments for pancreatic cancers. The technique was developed by scientists at the Francis Crick Institute.

Organ-on-a-chip – Organs in miniature format

01/02/2019

In vitro processes and animal tests are used to develop new medications and novel therapeutic approaches. However, animal testing raises important ethical concerns. Organ-on-a-chip models promise to be a feasible alternative. In a system the size of a smartphone, organs are connected using artificial circulation.

Multi-Organ Chips – The Patients of Tomorrow?

01/02/2019

The liver, nervous tissue or the intestines: all are important human organs that have in the past been tested for their function and compatibility using animal or in vitro test methods. In recent years, TissUse GmbH, a spin-off of the Technical University of Berlin (TU Berlin), has launched multi-organ chip platforms. But that’s not all.

Can a blood test detect lung-transplant rejection?

29/01/2019

Researchers have developed a simple blood test that can detect when a newly transplanted lung is being rejected by a patient, even when no outward signs of the rejection are evident.

AI ensures dynamic sitting

22/01/2019

Whether in the office, at school or behind the wheel: we spend a lot of time sitting and often stay in the same position for too long. The possible side effects are stiffness, back problems and pain. The SensA-Chair smart seating solution combats decreased mobility and ensures dynamic sitting.

Drug sponge could minimize side effects of cancer treatment

11/01/2019

With the help of sponges inserted in the bloodstream to absorb excess drugs, doctors are hoping to prevent the dangerous side effects of toxic chemotherapy agents or even deliver higher doses to knock back tumors, like liver cancer, that don't respond to more benign treatments.

AI approach outperformed experts in identifying cervical precancer

11/01/2019

A research team led by investigators from the National Institutes of Health and Global Good has developed a computer algorithm that can analyze digital images of a woman's cervix and accurately identify precancerous changes that require medical attention. This artificial intelligence (AI) approach, called automated visual evaluation.

Imaging technique brings diagnostic potential into operating room

07/01/2019

A team of University of Illinois at Urbana-Champaign researchers led by Prof. Stephen Boppart has successfully visualized the tumor microenvironment of human breast tissue after it was surgically removed from a patient in the operating room by using a new portable optical imaging system. This work marks a major step toward providing cancer researchers with a tool for tracking tumor progression.

World's first robotic bilateral breast reconstruction

10/12/2018

A team of surgeons from the Perelman School of Medicine at the University of Pennsylvania are the first in the world to use a surgical robot to assist with a bilateral free flap breast reconstruction - a procedure in which tissue is taken from the lower abdomen and used to rebuild the breast. The robot allows surgeons to make a much smaller incision into the abdominal wall muscles.

Sensitive MRI diagnostics thanks to "elastic" contrast media

30/11/2018

Researchers from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) have found a method for obtaining high-quality images in magnetic resonance imaging (MRI), that requires less contrast medium compared to current methods. An “elastic” protein structure can absorb dissolved xenon in a self-regulating way: The greater the amount of this noble gas, the higher the quality of the image.

Researchers develop new surgical technique for studying the thymus

27/11/2018

Elisa Oltra, head of the Genetic Exppression and Immunity group of the Faculty of Medicine at the Catholic University of Valencia (UCV), in collaboration with Alejandro Caicedo, professor of the Department of Medicine of the University of Miami, have developed a surgical process which makes it possible to place functional fragments of the thymus in the anterior chamber of the eyes of mice.

Microscope measures muscle weakness

23/11/2018

Biotechnologists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a system to accurately measure muscle weakness caused by structural changes in muscle tissue. The new method allows muscle function to be assessed using imaging without the need for sophisticated biomechanical recordings and could in future even make taking tissue samples for diagnosing myopathy superfluous.

Lung Imaging – Keeping the Respiratory System Healthy

05/10/2018

Many people have damaged or suboptimally functioning lungs. An accurate diagnosis and subsequent treatment are vital to protect this life-sustaining organ. Modern imaging solutions help physicians and patients understand what happens inside the lungs.

Regenerative heart valves: from simulation to replacement

23/07/2018

Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.

Organ Care System: treatment under extreme conditions

08/05/2018

Multidrug-resistant organisms that are treated with a dosage that exceeds the regular dose a hundred times and at temperatures of over 40 degrees Celsius – the human organism is unable to handle it. Yet if the diseased organ is treated outside of the body, extreme conditions are an option. For the first time, physicians have succeeded in treating a severe case of pneumonia by using the OCS.

Precision surgery thanks to informative hyperspectral imaging

08/02/2018

When body tissue is reconnected during a tumor operation in the gastrointestinal tract, surgeons need information about the current state of these so-called anastomoses. The new, non-invasive hyperspectral imaging technology now makes it possible to measure the crucial parameters during surgery and thereby increase surgical precision.

Acute kidney injury: Early detection thanks to biomarker

08/11/2017

Major surgeries in the abdominal region often result in kidney injury in patients. Meanwhile, the clinical manifestations don't present until one or two days after the procedure. This causes physicians to lose valuable time to treat patients. The University Hospital Regensburg has researched a new concept for the treatment of kidney injuries for several years.

Irreversible Electroporation – Last hope for liver cancer patients

24/04/2017

Liver cancer is the fifth most common malignant tumor in the world. The tumor can be removed through surgery or by utilizing thermal ablation techniques. If a treatment with conservative methods is no longer possible, there is an alternative: irreversible electroporation (IRE). The effectiveness of this method was now confirmed by a clinical study.
