Reading tissues

The trend towards personalised medicine implies the development of targeted cancer therapy. Tissue based examinations by pathologists play a key role in this trend. However, the relevance is still underestimated as pathologist Professor Manfred Dietel noted in his lecture at the European Forum on Oncology 2010 in Berlin, which explained what pathology already actually renders to targeted cancer…

The future of mass spectrometry in laboratory medicine

The world consists of molecules – so do we. With the progression of measurement tools such as microscopes, centrifuges, or spectrometers, mankind is becoming better and better in identifying the substances from which our world is made. Today, with the technical developments in mass spectrometry, biomolecules can be weighted with the highest precision and accuracy ever known, placing it among…

New EU project CORONET

Interfaces between the brain and electrical circuits in technical devices or computers open new perspectives for basic research and medical application, e.g., for therapeutic brain stimulation and neuroprosthetics. The new EU project CORONET will develop the technological and theoretical foundations for such future “bio-hybrid” interfaces between biological and artificial nervous tissues.

Synapses recycle proteins for the release of neurotransmitters

Neurons communicate via chemical transmitters which they store in the bubble-like synaptic vesicles and release as required. To be able to react reliably to stimulation, neurons must have a certain number of "acutely releasable" vesicles. With the help of a new method, German neuroscientists have now discovered that neurons systematically recycle the protein components necessary for transmitter…

Cancer stem cells

Cancer stem cells (CSCs) are the engine that drives tumour growth. They can not only reproduce themselves but also differentiate to form all the specialised cells found within a tumour. While chemotherapy and radiotherapy non-specifically target all rapidly dividing cells, there is increasing evidence that CSCs are more resistant to these treatments. Report: Karoline Laarmann

Real-time tissue elastography as a complementary procedure

Tissue hardness provides radiologists and gynaecologists with significant information to help distinguish between benign and malignant tumours. Tumour tissue is harder and less malleable than normal glandular and fatty tissues. Therefore, the classification of tissue hardness determines whether a biopsy is necessary. For breast diagnoses, real-time tissue elastography, along with conventional…

The notable risks in the use of bone cement

Used in numerous orthopaedic medical procedures, PMMA is a self-curing two component system that includes liquid and powder components. The liquid is methylmethacrylate monomer, a known deadly toxin, and PMMA toxicity is well documented in medical journals and regulatory publications. After many years of reported patient issues related to PMMA, doctors began calling these surgical complications…

Protein highways keep tissues organized

Precise regulation of tissue architecture is critical for organ function. Single cells build up a tissue by communicating with their environment and with other cells, thereby receiving instructions on whether to divide, change shape or migrate. An interdisciplinary group of researchers from several Max Planck Institutes have now identified a mechanism by which skin cells organize their interior…

A bright future for biobanks

Ten years ago, molecular biologist Dr Peter H J Riegman set up a unique bio-bank for medical research at the pathology department of Erasmus Medical Centre, Rotterdam, The Netherlands. The Erasmus MC Tissue Bank now holds 30,000 samples from about 15,000 patients. However, when Dr Riegman discusses his bio-bank with international colleagues they do not immediately associate it with a clinic or…

The European Network for Cell Imaging and Tracking Expertise (ENCITE)

Since June 2009, the focus of research in the European Network for Cell Imaging and Tracking Expertise (ENCITE) has been on finding biomarkers to aid cell transplantation. Funded with €11 million from the European Commission (EC), this major project that runs until 2013, involves 10 countries. Their work is coordinated by the European Institute for Biomedical Imaging Research (EIBIR) network,…

MR-Elastography

Physicians, over many centuries, have depended on the sense of touch as their hands on method to detect diseases in many body areas. This technique is called palpation. However, though it was known that abnormalities in the stiffness or mechanical environment in tissue may have a profound impact on how many diseases progress, conventional imaging modalities could not display tissue stiffness in…

Liver stiffness measurements identify patients with rapid or slow fibrosis

A recent study determined that repeated liver stiffness measurements (LSM) in the first year following liver transplant (LT) could discriminate between slow and rapid "fibrosers". LSM were extremely accurate, particularly at the 6-month post LT point, in detecting severity of fibrosis. Determining those at risk for a recurrence of hepatitis C virus (HCV) allows for early-stage administration of…

A Scaffold to regenerate lost bones and tissue

Mother Nature has provided the lizard with a unique ability to regrow body tissue that is damaged or torn - if its tail is pulled off, it grows right back. She has not been quite so generous with human beings. But we might be able to come close, thanks to new research from Tel Aviv University.

Molekulare Bildgebung von Karzinomen

Chirurgen an der Charité haben in kolorektalem Tumorgewebe eine spezifische Anhäufung von Protoporphyrin-IX (PpIX), einem rot-fluoreszierenden Vorläufermolekül des Häms beobachtet. Wir konnten zeigen, dass diese Anhäufung von PpIX darauf zurückzuführen ist, dass das Enzym, das PpIX normalerweise in Häm überführt, die sogenannte…
