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…

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.

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…

Cardiac Biomarkers

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…

TROCAR is on track

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…

Ultraviolet light - an invisible weapon against MRSA

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…

Tailoring cancer treatment with biomarkers

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…

C. difficile - Molecular scientists design a very quick cheap test

A small team of researchers at Barts and London School of Medicine and Dentistry, in London, has developed a rapid, cheap and effective kit to test for the presence of Clostridium difficile. And, they report that the new kit costs as little as 50 pence to £1 per test and can deliver results in under an hour, compared to commercial kits that cost up to £25 and in some cases take significantly…

Article • MRSA

Effective screening can kill several birds with one stone

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…

Dengue infection detection from first fever day

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.

ESBL: A greater danger than MRSA?

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…

Eppendorf launches the first segmented PCR plate

Eppendorf AG offers the first two-component PCR plate designed to be easily divisible, saving material and money when running smaller-scale experiments. These twin.tec unskirted 96-well plates fit almost all available PCR instruments and can be snapped into four separate 24-well segments and the empty wells saved for future use.

Article • Prostate cancer risk assessment

Novel p2PSA marker more accurate than PSA testing

The effectiveness of PSA (prostate-specific antigen) screening on reducing prostate cancer mortality was given a boost in 2009 when the conclusive findings from the 10-year European Randomized Study of Screening for Prostate Cancer (ERSPC) -- the world’s largest prostate cancer screening study – were published.

Developments in molecular evidence-based medicine and imaging

In the current economic environment the introduction of novel imaging approaches and their reimbursement by payers is becoming increasingly difficult. Historically, this denotes a significant change, in that many currently accepted routine tests or interventions were accepted based on common sense, convincing experience or rapid adoption into clinical routine without much scrutiny.

Molecular imaging in clinical practice

Over the past decades new imaging technologies have substantially broadened the range of imaging applications in clinical medicine. For years anatomical imaging modalities, such as X-ray and CT, reveal high-resolution information of organs and tissues over extended imaging ranges. Lately, however, the idea of functional imaging e.g. the visualisation of physiology in vivo gains importance.

The new world of biomarkers

While biomarkers are acknowledged as useful tools in the early assessment of patient response to treatment, radiologists are less clear on how they can be applied in clinical practice. The ECR session Biomarkers: new word, new world, new work? explored a number of new applications for biomarkers with senior radiologists discussing their relevance in different areas.

Exploring a new universe

Molecular imaging, the discipline that unites molecular biology and in vivo imaging technologies to assess biological activity in the body, promises to open up ‘…an entire new universe,’ declared Dr Ralph Weissleder, of the Centre for Molecular Imaging Research at Massachusetts General Hospital, USA, in the journal Radiology. That was just one decade ago. And he was right. It has indeed…

Shimadzu combines two vital strengths to create new molecular imaging technologies

Molecular imaging, a new science that emerged from molecular biology, is unlike traditional imaging. Whilst the latter can, for example, show the differences in proton density or water content on MRI, molecular imaging uses biomarkers (probes) that interact selectively with molecules within an area and then generate the image according to fine molecular alterations occurring inside (e.g. within a…
