Heroin vaccine blocks lethal overdose

23/02/2018

Scientists at The Scripps Research Institute (TSRI) have achieved a major milestone toward designing a safe and effective vaccine to both treat heroin addiction and block lethal overdose of the drug. Their research, published today in the journal Molecular Pharmaceutics, shows how a new anti-heroin formulation that is safe in animal models remains stable at room temperature for at least 30 days.

They enter cells, are activated by ultrasonic radiation and destroy the cells using the generated vibration.

Hospital crisis communication: A crisis knows no rules

02/03/2015

Crises come in many shapes and sizes. Whether it’s poor hygiene, thefts or treatment errors – once the crisis has arrived, things need to move quickly. For hospitals in particular, the right crisis communication is key. Yet many medical facilities still neglect the fact that crisis communication starts before the actual crisis takes place.

Digital pathology: From microscope slide to virtual microscopy

02/02/2015

The digitization of medicine moves on. Researchers, physicians and patients equally benefit from this development – thanks to improved diagnostics with highly sensitive devices, today findings can be comprehensively analyzed and treatment decisions made on a broadened basis. Digitization also offers the area of pathology interesting fields of application.

IBD: When genetics and environment interact

05/01/2015

T-cells are the guardians of our immune system. When they show changes, it can lead to severe inflammatory responses in the body. It is believed that the T-cells in persons who are affected by inflammatory bowel disease don’t work properly. Two proteins that can be found on activated T-cells and that interact with each other are now being analyzed.

Wound treatment with fish skin

03/11/2014

The treatment of chronic wounds is extremely problematic. Chronic wounds can take months or years to heal and some even never heal resulting in over 100.000 amputations taking place annually in the US alone. A new technology from Iceland, that is based on fish skin and is already used clinically, allows for improved healing of chronic and burn wounds.

Xenon magnetic resonance imaging: making pathological changes in the body visible

03/11/2014

As an imaging procedure, magnetic resonance tomography has become essential in clinical practice, since it can easily make organs and tissue visible. However, until now abnormal cancer cells or small centers of inflammation remained almost invisible. Now cell biologists from Berlin, Germany, have succeeded in fixing this problem with xenon magnetic resonance imaging.

Laboratory in Space: Hot on the Trails of Cartilage Degradation

01/10/2014

On November 10, 2014, astronaut Alexander Gerst will return to Earth from the International Space Station (ISS). He is not just anxiously expected by his family, but also by Dr. Anna-Maria Liphardt from the Institute of Biomechanics and Orthopedics at the German Sport University Cologne

Cultured skin makes large-scale transplantations possible

01/07/2014

Large burns require skin grafting. Surgeons remove split-thickness skin grafts and apply them to the injured areas. Now skin that has been made in a laboratory is meant to help in covering burns as well as chronic wounds and thus promote the healing process. Researchers in Zurich have been working on this for more than 13 years.

Diagnosing Parkinson's: the skin is revealing

01/07/2014

In patients with Parkinson's, neural cells in the brain die off that produce the neurotransmitter dopamine. Certain physical symptoms that can indicate the disease follow years later. But a reliable diagnosis can only be made through examination of the brain after the patient's death, and not during his lifetime.

Fat is the best medicine: "Adipose tissue contains many multipotent stem cells, approximately 500 times more than bone marrow"

01/07/2014

The not so popular “love handles“ could revolutionize medicine in the near future. In cooperation with the University of Rostock (Professor Hermann Seitz), the human med AG Company currently seeks to develop a device that is able to gently remove adipose tissue during surgery and subsequently isolate stem cells.

"We don’t know why certain pharmaceuticals bind especially well while others bind barely at all"

10/02/2014

Prof. Joachim Heberle from the Free University of Berlin wants to make the smallest protein structures visible under the microscope. He wants to accomplish this with an infrared microscope, originating in the field of physics. He told MEDICA.de which technology is behind all this and what he also wants to examine with it in the future.

Surgery: "Our camera detects the tiniest remainder of a tumor"

03/02/2014

Differentiating tumor tissue from healthy tissue isn’t always easy for surgeons. Scattered cancer cells and early cancer are often hard to detect with the naked eye. A special camera now makes even the tiniest remainder of a tumor visible during surgery.

"The immunosensory system goes beyond the actual immune cells"

22/01/2014

It guards the body but can become its enemy: the immune system defends us from intruding pathogens; it is also able to cause severe diseases if it falsely recognizes the body itself as a threat. Molecular receptors in the whole body enable the immune system to “sense” what happens within.
