IFCC-WORLDLAB BERLIN 2011
‘Heal the world’ sang the Berliner Rundfunk Children’s Choir and Youth Orchestra, and thus aptly began the joint 21st International Congress of Clinical Chemistry and Laboratory Medicine and the 19th IFCC-EFCC European Congress of Clinical Chemistry and Laboratory Medicine, attracting 4,418 delegates, 2,833 visitors and 1,058 exhibiting staff to Berlin in May.
Copper: The relentless killer on our side
Professor Bill Keevil, Director of the Environmental Healthcare Unit at University of Southampton’s School of Biological Sciences, was among the first microbiological researchers to experiment on copper’s efficiency against pathogenic and nonpathogenic strains of E. coli bacteria and demonstrate the inherent anti-microbial property of the metal.
Concerted efforts to combat prosthetic joint infections
Bacteria are highly flexible when it comes to choosing a vehicle to enter a human body. During orthopaedic surgery, they may well settle on a prosthetic joint and cause immediate or delayed infections.
From friend to foe
It’s a war against a perceived enemy that is not – autoimmune disease like rheumatoid arthritis, lupus erythematosus or multiple sclerosis, occur when the immune system attacks normal tissue components. Characteristic of those disease patterns are autoantibodies in the blood, which the immune system produces to attack its own organism.
Article • Artificial insemination
France: The country’s first ‘saviour sibling’ is a ‘double-hope baby’
The birth, in France, of its first baby to be conceived by artificial insemination on top of the selection of an embryo based on its blood, has sent new flames into the hot parliamentary debate over the reform of bioethics law.
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…
Protecting a specialty and warding off commercialisation
For some time, German pathology has only been in the background of the medical disciplines. However, during the last ten years the profession stepped up to the fore. In the face of molecular medicine developments, the German Association of Pathologists redefined its members position with revived self-confidence.
Advancing POC diagnostics
Improvements in microfluidics and detection technologies are beginning to expand the range of point-of-care diagnostics beyond simple blood chemistry tests to sophisticated immuno-assays and molecular diagnostics. Though yet to see much adoption in European hospitals, these point-of-care (POC) diagnostics are coming into use in the USA, initially in emergency rooms and ICUs where fast results are…
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…
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…
Luminous Jellyfish cells and early cancer diagnosis
It sounds like an idea plucked from the realms of science fiction writing. But in this case, there is nothing fictional about it. Scientists in Yorkshire have developed a process that uses the luminous cells from jellyfish to diagnose cancers deep within the human body.
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
1000 Genomes Project publishes analysis of completed pilot phase
Small genetic differences between individuals help explain why some people have a higher risk than others for developing illnesses such as diabetes or cancer. In the journal Nature, the 1000 Genomes Project, an international public-private consortium, published the most comprehensive map of these genetic differences, called variations, estimated to contain approximately 95 percent of the genetic…
Biomarkers - Keys to prevention and early detection
Biomarkers as the key to prevention and early detection were the subject this autumn at the 7th Annual Congress of the German Society for Clinical Chemistry and Laboratory Medicine (DGKL) in Mannheim. For the DGKL president Professor Karl J Lackner MD, Director of the Institute for Clinical Chemistry and Laboratory Medicine at Johannes Gutenberg University, Mainz, the topic is of increasing…
The MIRACLE begins
Detection of circulating and disseminated tumour cells in blood is a promising method to diagnose cancer dissemination, or to follow up cancer patients during therapy. Today’s methods and involve time-consuming (more than a day) sample processing and cell isolation steps -- all labour intensive and expensive. A lab-on-chip that could integrate those processing steps would enable faster,…
Cardiac and sepsis markers
Prior to October’s 3rd Annual Congress of the Austrian Society for Laboratory Medicine and Clinical Chemistry in Salzburg, Austria, laboratory experts conveyed their opinions in an interview with Michael Krassnitzer from European Hospital.
Urine protein could pave the way for new prostate cancer test
Scientists from the Cancer Research UK Cambridge Research Institute and The Institute of Cancer Research (ICR) built on earlier genome-wide research to link a genetic change associated with prostate cancer risk to a significant reduction in the amount of a protein called microseminoprotein-beta (MSMB). The protein - which regulates prostate cell death - is produced by normal prostate cells –…
Using fruit flies to help understand cancer
Small and with a life cycle of just two weeks, fruit flies are seen by many as pests and a problem all year round. However, for nearly a century, the humble insect, officially known as Drosophila melanogaster, which measures no more than 3mm, has performed a vital role in genetics and developmental biology. Fruit flies are genetically diverse and easy to use in research, helping scientists in a…
Cancer screening made simple
Current cervical cancer screening is time consuming and expensive, but now new breakthrough technology developed by European researchers should allow large-range screening by non-medical personnel with almost immediate results and at a much lower cost.
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…
Oncologists gather for ‘white nights’ in St Petersburg
White nights in St Petersburg draw in not only romantics, but June in this beautiful city also sees thousands of delegates arrive to attend the many scientific conferences and congresses. Among oncologists, the ‘white nights’ period means another annual scientific conference organised by the NN Petrov Research Institute of Oncology. For its continuing focus on breast cancer, the halls are…
Cervical cancer
Data from the ATHENA (Addressing THE Need for Advanced HPV Diagnostics) USA registration trial, involving more than 47,000 women, demonstrate that two human papilloma virus genotypes, HPV 16 and HPV 18, can identify those women with cervical pre-cancer missed by cytologic examination with a Papanicolau (Pap) test.
