Engineers at the University of Edinburgh have devised a fabric dressing whose thickness and elasticity can be custom-matched to specific areas of the body. The material is able to be absorbed by the skin’s own tissue as it heals. Two synthetic materials are blended to produce nanometre-sized fibres – thousands of times thinner than a hair – which can be fabricated in minutes. Edinburgh…
New results of a 65-year follow-up study of nearly 7,000 Norwegian patients with Multiple Sclerosis (MS) suggest that patients may have a greater overall risk of developing cancer than the general population, with an especially high risk of cancer in respiratory organs, urinary organs and the central nervous system. Presented at the 5th European Academy of Neurology (EAN) Congress in Oslo,…
Vaccinating schoolboys against the potentially deadly human papillomavirus (HPV) could dramatically reduce head and neck cancers in men, according to research involving the University of Strathclyde. The two-year project studied 235 patients in Scotland with head and neck cancer and found that 78% of people with head and neck cancers were men, while HPV was present in 60% of the cancers. This…
For over 20 years, a team of researchers at Lund University has worked on developing a drug against preeclampsia – a serious disorder which annually affects around 9 million pregnant women worldwide and is one of the main causes of death in both mothers and unborn babies. Now the researchers have published a study in the journal Scientific Reports that opens up opportunities for further…
Patients with biliary tract cancer have altered genetic architecture in some immune system receptor systems. This has been shown by researchers at Karolinska Institutet in Sweden in a new study published in the journal Gastroenterology. It is hoped that the discovery will lead to new effective immunotherapy for these difficult to treat tumour types. Biliary tract cancers, including…
Is computed tomography suitable for detecting lung cancer at a very early stage and thus still well treatable? Scientists at the German Cancer Research Center have investigated this with the LUSI study started in 2007. The results of the study, which is funded by the Deutsche Forschungsgemeinschaft and the Dietmar Hopp Foundation, are now available.
Half of Ebola outbreaks have gone undetected since the virus was discovered in 1976, scientists at the University of Cambridge estimate. The new findings come amid rising concern about Ebola in the Democratic Republic of Congo, and highlight the need for improved detection and rapid response to avoid future epidemics.
Wilmot Cancer Institute scientists believe they have figured out why a commonly used drug to treat late-stage prostate cancer often stops working after four or five months and appears to have a dual function that later turns the cancer into a relentless aggressor.
Having a child with a developmental disorder can cause parents to worry about the outcome of further pregnancies. In cases where the genetic mutation causing the disorder is not present in either parent it is assumed to be a one-off event with a very small chance of recurrence. But in some families, the risk of having another affected child is as high as 50%. Identifying such high-risk families…
An international group of researchers has found that antibodies to the human papilloma virus type 16 (HPV16) develop in the body between six to 40 years prior to a clinical diagnosis of throat cancer, and their presence indicates a strong increased risk of the disease.
Changes in certain sections of the genetic material of cancer cells, so-called microsatellites, can provide an important indication of whether immunotherapy may be successful in a patient with stomach or colorectal cancer. Scientists from Uniklinik RWTH Aachen, the German Cancer Research Center (DKFZ), the German Cancer Consortium (DKTK) and the National Center for Tumor Diseases Heidelberg (NCT)…
A genetic mutation that a Chinese scientist attempted to create in twin babies born last year, ostensibly to help them fend off HIV infection, is also associated with a 21% increase in mortality in later life, according to an analysis by scientists from UC Berkeley. The researchers scanned more than 400,000 genomes and associated health records contained in a British database, UK Biobank, and…
Scientists from Imperial College London and the University of Edinburgh have used gene-editing techniques to stop the bird flu virus from spreading, in chicken cells grown in the lab.
Eating too much fat and sugar makes you overweight and unhealthy – even young children know that. But why is that, and is there anything we can do about it? In a study published in the journal Cell, Prof. Jens Brüning's research group at the Max Planck Institute for Metabolism Research in Cologne has shown how altering fat metabolism in the liver can make obese mice thinner, despite eating an…
The production of artificial organs is a hot research topic. In the near future, artificial organs will compensate for the lack of organ donations and replace animal experiments. Although there are already promising experiments with 3D printers that use a „bio-ink“ containing living cells, a functional organ has never been created in this way. A European consortium coordinated by Dr Elena…
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…
People who experience anxiety symptoms might be helped by taking steps to regulate the microorganisms in their gut using probiotic and non-probiotic food and supplements, suggests a review of studies published in the journal General Psychiatry. Anxiety symptoms are common in people with mental diseases and a variety of physical disorders, especially in disorders that are related to stress.…
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…
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 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…
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…
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. The multicenter trial is sponsored by the University of Hamburg, financially supported by the biopharmaceutical company Adrenomed AG, and led by Dr.…
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…
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…
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…
