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 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…
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…
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 (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
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…
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.
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 –…
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,…
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…
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…
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.
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…
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…
Invited by Dr Mahdi Rezai, medical director of the breast centre at Luisen Hospital in Düsseldorf, Germany, and founder of the European Academy of Senology, some 1,400 international specialists attended the 8th Düsseldorf Breast Cancer Conference this June where leading experts evaluated new imaging methods.
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.
When in 1992 Dr Luigi Marzio Biasucci, head of the Sub-intensive Care Unit at the Catholic University of the Sacred Heart in Rome, Italy, published with his team the first paper on C-reactive protein (CRP) in unstable angina, few people believed in the diagnostic power of biochemical features to measure the effects or progress of disease, illness, or a condition. Today, biomarker tests are part…
Alere International* has launched three new next generation products: Troponin I -- a single-analyte, improved sensitivity Troponin I (TnI) test; Cardio2 -- a two analyte panel consisting of the new Troponin I and BNP, and Cardio3 -- a three analyte panel consisting of the new Troponin I, BNP and CK-MB.
Biopsy developed into an invaluable diagnostic tool in many organ systems. Advanced imaging technologies have helped shift biopsy techniques away from more invasive approaches toward imaging-guided percutaneous or through the skin techniques, according to a new study appearing online and in the September print edition of the journal Radiology.
The 3-year Translational Research On Combating Antimicrobial Resistance (TROCAR) project, a consortium of 14 European institutes, has completed its first year of molecular study of high-risk antibiotic-resistant bacteria. With expertise ranging from medical microbiology to computational analysis, this network of excellence is on track to identify and target the resistant and multi-resistant…
A few years ago, Dr Peder Bo Nielsen MD FRCPath, Consultant medical microbiologist at Northwick Park Hospital, London, UK, launched a research programme on airborne transmission of nosocomial infections. Until then, so called air-biology held no high priority in infection prevention and control. The prevailing perception was that colonisation and contamination mainly happens due to direct contact…
New biomarkers play a key role in individualised tumour therapy. They are important indicators for pathological processes in the body and for the use of adequate cancer drugs. In our European Hospital interview Professor Celso A Reis, from the Institute of Molecular Pathology and Immunology of the University of Porto (IPATIMUP*) in Portugal, discussed the current state of clinical use of…
The MRSA problem has been ignored almost stoically in many European countries for the past 20 years. Thus the number of resistant Staphylococci cases exploded from 1% in 1990 around 25% in 2010. However, the recognition that an infection can result in additional hospital costs of up to €10,000 has led to a change in thinking. The Netherlands, for example, declared war on MRSA with ‘search and…
It’s travel time, bringing all the possibilities of fun – as well as disease risk. The dengue virus, eg, is endemic in 124 countries. It is carried and transmitted by mosquitoes. Typically, what follows is a non-fatal febrile illness characterised by fever, muscle pain, headache, and nausea and vomiting lasting 5-7 days.
In hospitals, MRSA is considered Public Enemy Nr 1, and the increase in nosocomial infections, worldwide, has drawn universal attention to this ‘superbug’. However, Staphylococcus aureus is not alone – other pathogens are proving their resistance to antibiotics, in the last decade, gram-negative enterobacteria, which form the enzyme extended-spectrum beta-lactimases (ESBL), have joined the…
