Adult-onset IBD linked to higher mortality
While the onset of inflammatory bowel disease (ulcerative colitis or Crohn’s disease) in adulthood is tied to a higher mortality, the actual number of deaths has been falling, a Swedish study from Karolinska Institutet published in the journal Gut reports. Now it is a case of ascertaining which of the newer treatments are the most efficacious, say the researchers. Using the Swedish National…

Mapping bone-marrow microenvironment sheds fresh light on leukaemia
Stem cells are surrounded and protected by the stem-cell niche – the microenvironment – of the tissue in which they are found. Researchers at Karolinska Institutet have mapped the stem-cell niche in the bone marrow of mice and studied how it is influenced by developing leukemia. Their results, which are published in the journal Cell, show that the bone-marrow microenvironment is more complex…

Leonardo da Vinci: pure genius or ADHD?
Professor Marco Catani suggests the best explanation for Leonardo da Vinci's inability to finish his works is that the great artist may have had Attention Deficit and Hyperactivity Disorder. Leonardo da Vinci produced some of the world’s most iconic art, but historical accounts of his work practices and behaviour show that he struggled to complete projects. Drawing on these accounts, Professor…

Systems biology of antibiotics
Bacteria have fascinating properties. They adapt excellently to their respective environment, and they existed long before humans. Their toughness has led to the fact that bacteria have successfully spread all over the world for three billion years – even in places where humans could not survive, for example in the hottest springs and in the coldest places on earth. However, they were only…

A recent study can help governments understand which diagnostic laboratory tests are most important when developing universal health coverage systems. Researchers from five countries found that diagnostic laboratory tests are used similarly around the world, even though the institutions they studied differed in terms of poverty levels, health systems and prevalence of disease. “Even though…

Nano-signature discovery could revolutionise cancer diagnosis
A quick and easy test to detect cancer from blood or biopsy tissue could eventually result in a new approach to patient diagnosis. The test has been developed by University of Queensland researchers Dr Abu Sina, Dr Laura Carrascosa and Professor Matt Trau, who have discovered a unique DNA nanostructure that appears to be common to all cancers. Cancer is an extremely complicated and variable…

Early exposure to nicotine predisposes brain to addiction
Neonatal exposure to nicotine alters the reward circuity in the brains of newborn mice, increasing their preference for the drug in later adulthood, report researchers at University of California San Diego School of Medicine in a study published in Biological Psychiatry. A UC San Diego School of Medicine team of scientists, headed by senior author Davide Dulcis, PhD, associate professor in the…

First use of vasoprotective antibody in cardiogenic shock
Scientists at the German Centre for Cardiovascular Research (DZHK) have started a study to find out whether a monoclonal antibody restoring vascular integrity is safe and has positive effects on organ functions of patients with cardiogenic shock.

Cancer drugs promote stem cell properties of colorectal cancer
Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Mannheim University Medical Center have now discovered that a certain group of cancer drugs (MEK Inhibitors) activates the cancer-promoting Wnt signalling pathway in colorectal cancer cells. This can lead to the accumulation of tumor cells with stem cell characteristics that are resistant to many…

Bowel cancer rising among young adults in Europe
The rate of bowel cancer – also known as colorectal cancer or CRC – is rising among adults aged 20-49 in Europe, suggests new research. Rates rose most steeply among the youngest age group (20-29 years), and the authors warn that if the trend continues, screening guidelines may need to be reconsidered. Rates tend to be lower among people over 50, but the opposite is true among younger adults…

Targeting cancer cells with gold nanorods
Scientists at the University of Birmingham are working with a Canadian tech company to investigate whether gold nanorods can be used to target cancer cells in the human body. They have joined experts at Sona Nanotech Inc. to develop the next generation of nanorods for tissue imaging. The team will work with its Canadian partners - beginning by creating luminescent nanorods by transforming gold…

'Decoy' antibiotics dupe bacteria’s defences
Imperial medical students have helped to devise a new type of ‘decoy’ drug to tackle infections that are resistant to antibiotics. In lab tests on bacterial cultures, the new drug successfully killed a strain of drug-resistant bacteria. It works by delivering two antibiotics, one of which is effectively hidden. When the bacteria fight against the first ‘decoy’ antibiotic, this action…

Ribosome inhibition may hold the key to multi-stage cancer treatment
Nearly 90% of all cancer patient deaths are due to metastasis. A study from Uppsala University shows that a process that allows the cells to metastasise is aided by the synthesis of new ribosomes, the cell components in which proteins are produced. The results open the possibility for new treatment strategies for advanced cancers. The study is published in Nature Communications. As tumours…

Induced pluripotent stem (iPS) cells are among the most important tools in modern biomedical research, leading to new and promising possibilities in precision medicine. To create them requires transforming a cell of one type, such as skin, into something of a blank slate, so it has the potential to become virtually any other kind of cell in the body, useful for regenerative therapies for…
