An organic compound produced by the gut flora – the metabolite 4-Cresol – is considered to have protective effects against both type 1 and 2 diabetes, notably by stimulating the growth of the insulin-producing pancreatic beta cells. This is according to a new study led by Inserm researcher Dominique Gauguier at the Environmental Toxicology, Therapeutic Targets, Cell Signaling and Biomarkers…
Scientists have created one of the most detailed maps of breast cancer ever achieved, revealing how genetic changes shape the physical tumour landscape. An international team of scientists, brought together by a £20 million Grand Challenge award from Cancer Research UK, has developed intricate maps of breast tumour samples, with a resolution smaller than a single cell. These maps show how the…
Researchers from Karolinska Institutet, Örebro University and Aarhus University, Denmark, have published the largest study to date on the risk of colorectal cancer in Crohn's disease. The article is published in the journal The Lancet Gastroenterology Hepatology. Crohn's disease is a chronic inflammatory bowel disease (IBD). Several previous studies have reported an increased risk of colorectal…
A surprising discovery about a rare form of childhood brain cancer suggests a new treatment approach for that cancer – and potentially many others. Researchers at the University of Virginia School of Medicine have determined that the supposedly simple cancer, called medulloblastoma, forms an unexpectedly intricate network to drive its growth. Some tumor cells actually turn into another type of…
Research into the novel Wuhan seafood market pneumonia virus, the deadly "coronavirus" that has forced the Chinese government to quarantine more than 50 million people in the country's dense industrial heartland, will be facilitated by the UC Santa Cruz Genomics Institute. The Genomics Institute's Genome Browser team has posted the complete biomolecular code of the virus for researchers…
Scientists at the University of Bologna have conducted the largest analysis of coronavirus 2019-nCoV genomes sequenced so far. This analysis confirms that the virus originates in bats and shows a low variability: the virus heterogeneity is low. At the same time, researchers identified a hyper-variable genomic hotspot in the proteins of the virus responsible for the existence of two virus…
Scientists suggest a new strategy that uses induced pluripotent stem cells (iPSCs) to regulate immune reaction to transplanted tissues. The team, led by Professor Ken-ichiro Seino of Hokkaido University’s Institute for Genetic Medicine, found that thymic epithelium cells derived from mouse induced pluripotent stem cells (iPSCs) can regulate immune response to skin grafts, extending their…
Eric Prossnitz, PhD, from the University of New Mexico Health Services and his team hope to help 93 million obese Americans fight their fat. In a paper published in Science Translational Medicine, they reported that G-1, a cancer-fighting compound they discovered some years ago, reduces fat in obese mice. Although G-1 is currently in phase 1 clinical trials for cancer, Prossnitz and his team are…
The situation is extraordinary: there have only ever been four declarations of public health emergencies of international concern in the past and now there are two at the same time. Whilst the risks associated with the novel coronavirus are still unclear, people in the Democratic Republic of the Congo are still battling with an outbreak of the deadly Ebola virus which has been ongoing since 2018…
The novel coronavirus that recently originated in Wuhan, China has grabbed headlines and caused concern among public health officials around the world. Two infectious disease experts share their insights on the novel coronavirus epidemic.
Researchers discover a novel checkpoint in immune cells with the potential to treat the cancer cell microenvironment. The recognition of bacterial infections or foreign substances is mediated and controlled by the human immune system. This innate and adaptive immune system comprises the most important metabolic and cellulare processes to fight against infections and other diseases. Paradoxically,…
A team of researchers from Osaka University, Kyoto Prefectural University of Medicine, and Toppan Printing Co., Ltd. succeeded in reconstructing adipose tissue balls (“mini-breasts”) with a functional vascular network using patient-derived cells, achieving a high graft survival rate in small animal models. So far, silicone breast implants were primarily used in breast reconstruction following…
In their quest to find new and better methods to make cancer cells more susceptible to treatment, Karin Lindkvist and her research group at Lund University in Sweden are looking into the world of molecules, using the X-rays at the MAX IV laboratory. The researchers believe that limiting the cells' access to sugar will make cancer cells more sensitive to treatment. Many of the cancer treatments…
T cells play a huge role in our immune system's fight against modified cells in the body that can develop into cancer. Phagocytes and B cells identify changes in these cells and activate the T cells, which then start a full-blown program of destruction. This functions well in many cases – unless the cancer cells mutate and develop a kind of camouflage that let them escape the immune system…
Researchers at Linköping University (LiU) have developed an algorithm that can identify patients at a higher risk of septic shock, a life-threatening condition that is difficult for doctors to predict. At the same time, it is important to recognise the symptoms as early as possible, since early treatment increases the chance of survival. A group of LiU researchers is using artificial…
One of the causes of breast cancer may be inflammation triggered by harmful bacteria say researchers. Scientists say their idea – as yet unproven – is supported by the available evidence, which is that bacterial induced inflammation is linked to cancer. The paper in the journal Medical Hypotheses is by Lancaster University medical student Auday Marwaha, Professor Jim Morris from the…
Fireworks associated with festival celebrations such as Australia Day, China’s Lunar New Year and Fourth of July, in the USA, may have a significant impact on the health of vulnerable people, a new study reveals. Using fireworks during these celebrations generates anthropogenic source of air pollutants with significant impacts on local air quality, creating up to eight times the average of…
New research indicates that subtle structural features of donated kidneys from living donors may predict the risk of kidney transplant failure in recipients. The findings, which appear in an upcoming issue of JASN, may help clinicians as they evaluate the quality of organs at the time of transplantation. The quality of donated kidneys obtained from living donors is often inferred from their age,…
Does the blood we thought to know so well contain elements that had been undetectable until now? The answer is yes, according to a team of researchers. The scientistts from Inserm, Université de Montpellier and the Montpellier Cancer Institute (ICM) working at the Montpellier Cancer Research Institute (IRCM), have revealed the presence of whole functional mitochondria in the blood circulation.…
The British Heart Foundation (BHF) announced its shortlist of four research projects competing for a single £30 million award. The charity says it is one of many radical new approaches needed to address a frightening mismatch in research funding compared with the burden of heart and circulatory diseases.

Nine people have died and more than 400 have been sickened by the new corona virus spreading in China. A few cases have been confirmed in Taiwan, Thailand, South Korea, Japan and the U.S., and on Wednesday, the World Health Organization is holding an emergency meeting on the outbreak. How worried about a new pandemic should we be? Virus researcher Ali Mirazimi, adjunct professor at the Department…
Diseases such as cardiovascular diseases, cancer or certain lung diseases are among the most common non-natural causes of death today and account for about 70 percent of deaths worldwide. They are defined by the World Health Organization (WHO) as non-communicable because they are assumed to be caused by a combination of genetic, lifestyle and environmental factors and cannot be transmitted…
Twice as many people as previously believed are dying of sepsis worldwide, according to an analysis published in The Lancet and announced at the Critical Care Reviews annual meeting in Belfast. Among them are a disproportionately high number of children in poor areas.
A probiotic drink could become a promising new weapon in the battle against antibiotic resistant bacteria, after a team of scientists at the University of Birmingham engineered and patented a key genetic element that can tackle the genetic basis of resistance. The team is now seeking funding for a clinical trial for the drink which has potential to work against many resistant bacteria commonly…
University of Liverpool researchers have used a newly developed eye movement test to improve the understanding of how parts of the brain work. Healthy, older adults are widely reported to experience cognitive decline, including impairments in inhibitory control (the ability to stop ourselves thinking or doing things). However, because ageing effects on inhibitory control are highly variable…
