Kiel biochemistry research team proves the existence of a previously unknown alternative cholesterol transport mechanism inside cells. Cholesterol is a vital cell building block in humans and animals, and an integral part of the so-called cell membrane. This boundary layer separates the interior of the cell from the neighbouring cells and the surrounding environment. By means of certain proteins,…
Researchers at ETH Zurich have refined the famous CRISPR-Cas method. Now, for the very first time, it is possible to modify dozens, if not hundreds, of genes in a cell simultaneously. The biotechnological method CRISPR-Cas offers a relatively quick and easy way to manipulate single genes in cells, meaning they can be precisely deleted, replaced or modified. Furthermore, in recent years,…
A novel neck brace, which supports the neck during its natural motion, was designed by Columbia engineers. This is the first device shown to dramatically assist patients suffering from Amyotrophic Lateral Sclerosis (ALS) in holding their heads and actively supporting them during range of motion. This advance would result in improved quality of life for patients, not only in improving eye contact…
Researchers from Northwestern University are using Argonne supercomputers to advance the development of an optical microscopy technique that can predict and quantify cancer risks at extremely early stages. The basic principle driving Allen Taflove’s computational electrodynamics research — which bears the potential to transform how we diagnose, and possibly treat, various forms of cancer —…
Researchers at ETH Zurich have developed a new method for producing malleable microstructures – for instance, vascular stents that are 40 times smaller than previously possible. In the future, such stents could be used to help to widen life-threatening constrictions of the urinary tract in foetuses in the womb. Approximately one in every thousand children develops a urethral stricture,…
Surgery complications, implant rupture, tissue contractures or even plain immune intolerance – silicone breast implants can cause a variety of unfavourable conditions. Because of this, many women think twice about breast augmentation. A new kind of implant might change this up a bit. BellaSeno GmbH, a company developing absorbable implants using additive manufacturing technology, now announced…
Neurons of the central nervous system (CNS) shut down their ability to grow when they no longer need it; this is commonly accepted knowledge. This occurs normally after they have found their target cells and established synapses. However, recent findings show that old nerve cells have the potential to regrow and to repair damage similar to young neurons. The underlying mechanisms for this…
Mayo Clinic and Boston Scientific Corp. have launched a new venture to accelerate the development of medical technology and new minimally invasive treatments for many health conditions that impede quality and longevity of life. The accelerator, known as Motion Medical, will have its research facilities in One Discovery Square, the bioscience center in the Discovery Square research district. Both…
Researchers identified how to kill therapy-resistant cells in hypoxic tumors and in cells arising in the von Hippel-Lindau hereditary cancer. In a recent publication in PNAS, the research group identified how to kill therapy-resistant cells in hypoxic tumors and in cells arising in the von Hippel-Lindau (VHL) hereditary cancer.
The traditional classification of diabetes, mainly in type 1 and type 2 diabetes, has been challenged by studies from Scandinavia. In the current issue of The Lancet Diabetes & Endocrinology, researchers from DDZ together with colleagues from DZD and University of Lund published a cluster analysis of diabetes allowing for phenotyping into subgroups, which extended the findings by showing that…
A group of scientists from Vilnius University have developed the world’s fastest DNA testing method, reducing DNA testing costs by 90%. It identifies changes in chromosomes, genes, or proteins to determine a genetic condition or eliminate the chance of the formation or passing on of a gene-based disorder amongst humans and animals. At present, the sole method of genetic testing is the DNA…
A new study from Aarhus University Hospital and Aarhus University has shown that probably 1 in 4 people in the world carry the tuberculosis bacterium in the body. The disease tuberculosis is caused by the bacterium Mycobacterium Tuberculosis, which affects more than 10 million people every year, and kills up to 2 million, making it the most deadly of the infectious diseases.
A new study harnessed the unique genetic history of the people of Finland to identify variations in DNA that might predispose certain individuals to disease, whether or not they are Finnish themselves.
As the largest organ of the human body, our skin is astounding. It protects us from infection, endures radiation, senses temperature, and is flexible enough to withstand our everyday activities. What holds this all together is the protein we all know and love: collagen. In a paper published in Scientific Reports a team from Japan found for the first time that collagen in the skin is organized in…
Women with pre-eclampsia during pregnancy have a five-fold increased risk of end stage kidney disease (ESKD) later in life compared to women who don’t develop pre-eclampsia during pregnancy, according to a new study. Professor Louise Kenny from the University of Liverpool is one of the co-authors of the study, which is published in PLOS Medicine and also involved researchers at University…
Researchers at the University of Birmingham have shown that it’s possible to produce a compound with anti-cancer properties directly from feverfew – a common flowering garden plant. The team was able to extract the compound from the flowers and modify it so it could be used to kill chronic lymphocytic leukaemia (CLL) cells in the laboratory. Feverfew is grown in many UK gardens, and also…
Advanced computer models of diseases can be used to improve diagnosis and treatment. The goal is to develop the models to “digital twins” of individual patients. Those twins may help to computationally identify and try the best medication, before actually treating a patient. The models are the result of an international study, published in the open access journal Genome Medicine.
New research has found that antibiotic-resistant strains of Klebsiella pneumoniae, an opportunistic pathogen that can cause respiratory and bloodstream infections, are spreading through hospitals in Europe. Certain strains are resistant to the carbapenem antibiotics that represent the last line of defence in treating infections and are therefore regarded as extremely drug resistant (XDR).
A new way of concentrating radiotherapy dose in tumours, while minimising damage to healthy cells, has been proposed in research led by scientists at the University of Strathclyde. The study proposes that focusing high-energy particle beams on a small spot deep inside the body could potentially enable clinicians to target cancerous tumours precisely, while reducing the dose to surrounding tissue.…
Skin cancer is the most common cancer in the U.S., affecting one in five Americans in their lifetime. Limiting exposure to ultraviolet radiation is the number one way individuals can reduce their risk of skin cancer, though new data suggests that UV exposure is on the rise, particularly among Caucasian girls and young women. Research presented at the 2019 American Academy of Dermatology Summer…
Researchers at St George's, University of London have developed an accurate equation that will enable medical professionals to accurately predict body fat levels in children using only very simple measurements and other information. The equation takes into account height, weight, sex and age and ethnicity (where available) to predict body fat. The equation has been derived using information from…
Clinical trials are a critical tool for getting new treatments to people who need them, but research shows that difficulty finding the right volunteer subjects can undermine the effectiveness of these studies. Researchers at Cincinnati Children’s Hospital Medical Center designed and tested a new computerized solution that used artificial intelligence (AI) to effectively identify eligible…
Prebiotics are currently a preferred treatment for certain metabolic disorders, as they can restore the balance of dysfunctional gut microbiota, and improve the body’s metabolism. However, these substances have to be used at high doses, which can result in patients experiencing bloating and flatulence. A research group led by Matteo Serino, Inserm researcher at the Digestive Health Research…
Our eyes – considered by many to be the windows to the soul – need constant care, and as we age, they sometimes also need significant repair. The panes of these windows – the corneas – are transparent tissues that have been the focus of some of the oldest and most common transplantation surgeries. Now thanks to researchers in Kyoto, some such transplants may become even safer. The team,…
A team led by scientists at the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) developed an algorithm that a computer could use to conduct a similar type of search in microbial and metagenomic databases. In this case, the machine “learned” to identify a certain type of bacterial viruses or phages called inoviruses, which are filamentous viruses with small, single-stranded DNA…
