Cancer ranks as a leading cause of death in every country in the world, and, for the first time, female breast cancer is the most commonly diagnosed cancer, overtaking lung cancer, according to a collaborative report, Global Cancer Statistics 2020, from the American Cancer Society (ACS) and the International Agency for Research on Cancer (IARC). Data show that 1 in 5 men and women worldwide…
Covid-19 patients who suffer a cardiac arrest either in or out of hospital are far more likely to die than patients who are not infected with the coronavirus. In particular, women have the highest risk of dying: they are nine times more likely to die after suffering a cardiac arrest in hospital, according to research published in the European Heart Journal.
Engineers at EPFL’s Center for Artificial Muscles have developed a silicone aorta that can reduce how hard patients’ hearts have to pump. Their breakthrough could offer a promising alternative to heart transplants. “Over 23 million people around the world suffer from heart failure. The disease is usually treated with a transplant, but because donated hearts are hard to come by, there is an…
A new EU-wide repository for health-related imaging data could boost development and marketing of AI tools for better cancer management. The open-source database will collect and harmonise images acquired from 40,000 patients, spanning different countries, modalities and equipment. This approach could eliminate one of the major bottlenecks in the clinical adoption of AI today: Data bias.
The continuing corona virus epidemic has impacted strongly on cancer care and research, including the delay of treatments and diagnoses as well as on trials of new therapies, and the shift in research to develop a Covid-19 vaccine. However, the session ‘Cancer research and Covid-19’, during the National Cancer Research Institute (NCRI) Virtual Showcase (online 2-3 November) looked at how UK…
A team of neuroscientists has identified a potential means to address the loss of cognitive function due to Alzheimer’s disease by targeting protein synthesis in mice. Their findings, reported in the journal Science Signaling, reveal that synthetic pharmaceuticals could rescue the activity of brain cells needed for memory formation.
In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases. Modeling these complex interactions in animals such as mice is difficult to do, because their…
The most deadly global health crisis in a century has resulted in a substantial decline in overall heart surgery volume and an unexplained increase in deaths after coronary artery bypass grafting, according to late-breaking research presented at the 57th Annual Meeting of The Society of Thoracic Surgeons.
Someone has a stroke every 40 seconds in the US, resulting in death every 4 minutes. Stroke is the leading cause of disability from a medical condition. When it happens, blood clots or bleeds kill a part of the brain – it goes dark – and can no longer control part of the body. People stop being able to walk, see, talk, or control their hand or arm the way they once did. Although treatments…
Evidence is emerging that vitamin D – and possibly vitamins K and A – might help combat Covid-19. A new study from the University of Bristol published in the journal of the German Chemical Society Angewandte Chemie has shown how they – and other antiviral drugs – might work. The research indicates that these dietary supplements and compounds could bind to the viral spike protein and so…
The emergence of SARS-CoV-2 virus variants that are adding twists in the battle against COVID-19 highlight the need for better genomic monitoring of the virus, says Katia Koelle, associate professor of biology at Emory University.
Researchers from Helmholtz Zentrum Muenchen, the Technical University of Munich and the German Center for Diabetes have discovered a novel and druggable insulin inhibitory receptor, named inceptor. The blocking of inceptor function leads to an increased sensitisation of the insulin signaling pathway in pancreatic beta cells. This might allow protection and regeneration of beta cells for diabetes…
Researchers at Vanderbilt University Medical Center (VUMC) and the University of Texas Medical Branch (UTMB) at Galveston have discovered what may be the Achilles' heel of the coronavirus, a finding that may help close the door on COVID-19 and possibly head off future pandemics.
Certain anchor proteins inhibit a key metabolic driver that plays an important role in cancer and developmental brain disorders. Scientists from the German Cancer Research Center (DKFZ) and the University of Innsbruck, together with a Europe-wide research network, discovered this molecular mechanism, which could open up new opportunities for personalized therapies for cancer and neuronal diseases.
B-cell lymphocytosis, a condition in which individuals have increased levels of particular white blood cells, in some cases leads to blood cancer. As an international team of researchers now shows in samples from patients, both diseases exhibit similar epigenetic signatures that are forming very early during the course of the disease. Chronic leukemias often start insidiously. White blood cells…
One more piece of the puzzle has fallen into place behind a new drug whose anti-cancer potential was developed at the University of Alberta and is set to begin human trials this year, thanks to newly published research. “The results provide more justification and rationale for starting the clinical trial in May,” said first author John Mackey, professor and director of oncology clinical…
When cancer is confined to one spot in the body, doctors can often treat it with surgery or other therapies. Much of the mortality associated with cancer, however, is due to its tendency to metastasize, sending out seeds of itself that may take root throughout the body. The exact moment of metastasis is fleeting, lost in the millions of divisions that take place in a tumor. “These events are…
Researchers at Lund University in Sweden, in collaboration with colleagues in Dresden, Germany, have developed a way of combining a bone substitute and drugs to regenerate bone and heal severe fractures in the thigh or shin bone. The study, published in the research journal Science Advances, was conducted on rats, but the researchers think that the method in various combinations will soon be…
New high-resolution structures of the bacterial ribosome determined by researchers at the University of Illinois Chicago show that a single water molecule may be the cause — and possible solution — of antibiotic resistance. The findings of the new study are published in the journal Nature Chemical Biology. Pathogenic germs become resistant to antibiotics when they develop the ability to…
With Covid-19 dominating medical science and human concern, chemists at the University of Sydney have developed a method to quickly and safely synthesise protein vaccines for respiratory diseases for pre-clinical tests. Their approach can be used to test vaccine strategies against novel pandemic pathogens such as SARS-CoV-2, the virus that causes Covid-19.
To quickly and correctly diagnose diseases, medical professionals depend on identifying what biochemicals are present in tissue sections, where the biomolecules are, and at what concentrations. Mass spectrometry imaging—which can identify multiple biochemicals in a single experiment—is a promising technique to achieve this. However, the stability of biomolecular sampling needs improvement to…
For several years, scientists worldwide have been investigating the extent to which microorganisms living in and on the human body influence central life processes and thus health and disease. Today they assume that there is a connection between the totality of the microbial colonization in the human body, called the microbiome, and the development of diseases. Chronic inflammatory bowel disease…
For the first time, scientists have come up with a precise atomic level explanation for why glulisine - a commonly used medication to treat diabetes - is faster acting than insulin. The findings, published in Scientific Reports, could have benefits for diabetes patients in ensuring that a more improved insulin can be developed for future treatment. The study was carried out by experts from the…
Fried-food intake is linked to a heightened risk of major heart disease and stroke, finds a pooled analysis of the available research data, published online in the journal Heart. And the risk rises with each additional 114 g weekly serving, the analysis indicates. It’s clear that the Western diet doesn’t promote good cardiovascular health, but it’s not clear exactly what contribution fried…
Our biological or circadian clock synchronizes all our bodily processes to the natural rhythms of light and dark. It’s no wonder then that disrupting the clock can wreak havoc on our body. In fact, studies have shown that when circadian rhythms are disturbed through sleep deprivation, jet lag, or shift work, there is an increased incidence of some cancers including prostate cancer, which is the…
