A hydrogel that forms a barrier to keep heart tissue from adhering to surrounding tissue after surgery was developed and successfully tested in rodents by a team of University of California San Diego researchers. The team of engineers, scientists and physicians also conducted a pilot study on porcine hearts, with promising results.
They describe their work in the June 18, 2021 issue of Nature Communications.
Most of us have heard of Alzheimer's disease, a neurodegenerative disorder marked by brain cell death and the shrinking of the brain. It is the most common cause of dementia and cognitive impairment, which typically have a devastating effect on a person's quality of life. There is still no cure for Alzheimer's.
The ability to insert desirable genes into animal or human cells is the basis of modern life science research and of widespread biomedical applications. The methods used to date for this purpose are mostly non-specific, making it difficult for scientists to control which cell will or will not take up a gene. For this gene transfer, the target genes are often packaged into "viral vectors." These are viruses in which part of the genetic material has been replaced by the target genes. When researchers add these viral vectors to cells, the vectors introduce the genes into the cells.
Tsukuba, Japan - Sometimes a dead log isn't just a dead log. This one in Japan turned out to be the habitat of a species previously unknown to science.
In a new study published in the journal Nematology, a University of Tsukuba-led research team has described a new species of nematode found inside bark beetles that emerged from a dead log of a fir tree.
Thousands of years ago, archaic humans such as Neanderthals and Denisovans went extinct. But before that, they interbred with the ancestors of present-day humans, who still to this day carry genetic mutations from the extinct species.
"Boomers" and "millennials" who go to church are more likely to trust their neighbours and donate to charity, according to a new study.
Religious beliefs and participation help close the gaps in civic participation between millennials and their elders, researchers have found.
An international survey by the University of Münster's Cluster of Excellence "Religion and Politics" provides the first empirical evidence of an identity-related political cleavage of European societies that has resulted in the emergence of two entrenched camps of substantial size. "We see two distinct groups with opposing positions, which we call 'Defenders' and 'Explorers'", says psychologist Mitja Back, spokesperson of the interdisciplinary research team that conducted the most comprehensive survey of identity conflicts in Europe to date.
RUDN University doctors found alterations in serum amino acid profile in children with attention deficit hyperactivity disorder (ADHD). The findings will help to understand the mechanism of the disorder and develop new treatment strategies. The study is published in the journal Biomedical Reports.
Testicular cancer is the most common cancer among men under 40 in Europe and the USA. National statistics from the Cancer League indicate 471 new cases and 12 deaths in Switzerland. In general, the prospects for successful treatment of testicular cancer are good over time and, especially with early diagnosis, even further improved. Even if metastases are already present, testicular cancer can be successfully treated with appropriate therapy in the majority of cases.
New classification enables even more targeted treatment
In the mid-14th century Europe was devastated by a major pandemic - the Black Death - which killed between 40 and 60 per cent of the population. Later waves of plague then continued to strike regularly over several centuries.
Plague kills so rapidly it leaves no visible traces on the skeleton, so archaeologists have previously been unable to identify individuals who died of plague unless they were buried in mass graves.
Whilst it has long been suspected that most plague victims received individual burial, this has been impossible to confirm until now.
Lugano, Switzerland, 17 June 2021 - Adding an immune checkpoint inhibitor to anti-HER2 treatment in breast cancer does not improve pathological complete response (pCR), according to the primary analysis of the IMpassion050 trial presented today during the ESMO Virtual Plenary. (1) The phase III trial is the first to report data comparing a neoadjuvant anti-HER2 based regimen with or without the anti-PD-L1 antibody atezolizumab in patients with high-risk, HER2-positive early breast cancer.
A study performed by researchers at the Institute for Advanced Chemistry of Catalonia (IQAC-CSIC) from the Spanish National Research Council (CSIC) in collaboration with Stony Brook University (USA) proposes a new strategy for the development of new drugs based on the inhibition of tyrosine kinase enzymes, molecules that activate and trigger many cellular processes. The results have been published in the Chemistry - A European Journal.
The German National Academy of Sciences Leopoldina and the German Council for Sustainable Development (RNE) have published a joint position paper presenting paths to climate neutrality by 2050. In it, the Leopoldina and the RNE highlight options for action to effect the changes needed within society, at political level and in the business world, in view especially of the urgency and the historic dimensions of the transformation we face. With the paper, the Leopoldina and the RNE are consciously not seeking to engage in a race to set the most ambitious target.
Abu Dhabi, UAE: Trans-Neptunian Objects (TNOs), small objects that orbit the sun beyond Neptune, are fossils from the early days of the solar system which can tell us a lot about its formation and evolution.
(Boston)--An intrauterine fracture is a rare finding during routine prenatal imaging. This condition can be due to maternal trauma, genetic disorders of the skeleton, as well as other predisposing maternal metabolic and vascular disorders. Genetic disorders that have previously been reported to cause intrauterine fracture include brittle bone disease (osteogenesis imperfecta or OI), osteopetrosis, hypophosphatasia and Ehlers-Danlos syndrome (EDS).
