According to the American Heart Association, heart disease is the leading cause of death worldwide in recent years. During a heart attack, or myocardial infarction (MI), a blocked artery and the resulting oxygen deprivation cause massive cardiac cell death, blood vessel impairment and inflammation. Now, researchers reporting in ACS Biomaterials Science & Engineering have developed a cardiac patch with tiny engineered blood vessels that improved recovery from MI in rats and pigs.
Dementia and other cognitive disorders now appear to be risk factors for developing severe COVID-19, according to research from the University of Georgia. The findings highlight the need for special care for populations with these preexisting conditions during the pandemic.
In a blind study, the researchers analyzed data from nearly 1,000 diseases and two specific genes to compare the health profiles of COVID-19 patients with those testing negative, looking for commonalities in the COVID-19 patients.
DALLAS - Oct. 28, 2020 - Two new studies suggest Medicare's system of penalizing hospitals if too many patients are readmitted within 30 days should also look at whether the patients were well enough to remain in their home during that time.
The studies propose adding a new metric to examine how many of the initial 30 days following hospitalization are actually spent at home - a "risk-adjusted 30-day home time" test to balance the current "30-day risk-standardized readmission rate" measure.
Fourteen out of every 1,000 COVID-19 patients admitted to hospital experience a stroke, a rate that is even higher in older patients and those with severe infection and pre-existing vascular conditions, according to a report published this week.
We're told from a young age not to eat too much sugar, but in reality, our bodies are full of the stuff. The surface of every living cell, and even viruses, is covered in a mess of glycans: long, branching chains of simple sugars linked together by covalent bonds. These cell-surface sugars are crucial for regulating cell-cell contact, including the attachment of bacteria to healthy host cells. Glycans are also found on all other biological polymers, including proteins and RNA, and their presence impacts the polymers' stability and function.
Ann Arbor, October 28, 2020 - A new study in the American Journal of Preventive Medicine, published by Elsevier, presents new data that address important questions pertaining to the containment of the coronavirus pandemic: When should COVID-19 quarantine really end and which continuing symptoms may be more indicative of a positive test in recovered patients?
Stromboli, the 'lighthouse of the Mediterranean', is known for its low-energy but persistent explosive eruptions, behaviour that is known scientifically as Strombolian activity. This feature has long been an attraction for tourists and volcanologists from all over the world.
The University of Cincinnati is decoding the genetics of agricultural pests in projects that could help boost crop and livestock production to feed millions more people around the world.
Joshua Benoit, an associate professor in UC's College of Arts and Sciences, contributed to genetic studies of New World screwworms that feed on livestock and thrips, tiny insects that can transmit viruses to tomatoes and other plants.
It's the latest international collaboration for Benoit, who previously sequenced the DNA for genomes of dreaded creatures such as bedbugs.
(New York, NY - October 28, 2020) - The vast majority of individuals infected with mild-to-moderate COVID 19 mount a robust antibody response that is relatively stable for at least five months, according to research conducted at the Icahn School of Medicine at Mount Sinai and published October 28, in the journal Science. Additionally, the research team found that this antibody response correlates with the body's ability to neutralize (kill) SARS-CoV-2, the virus that causes COVID-19.
CAMBRIDGE, MA -- As people age, they often lose their motivation to learn new things or engage in everyday activities. In a study of mice, MIT neuroscientists have now identified a brain circuit that is critical for maintaining this kind of motivation.
MINNEAPOLIS - Studies have suggested that taking part in leisure activities such as playing cards or gardening may be associated with a lower risk of developing dementia. But a new study found no association between taking part in leisure activities at age 56 and the risk of dementia over the next 18 years. The researchers also found that some people who are later diagnosed with dementia stop participating in leisure activities years before they are diagnosed.
DURHAM, N.C. -- Fall is here, and we see the leaves turning yellow, orange or red thanks to a trick of our vision: our brains categorize colors. Scientists have learned that birds with colorful markings do this too. But what about drab birds that don't rely on color?
According to a new Duke University study, the ability to mentally categorize colors is not a universal avian attribute, and dull-colored birds may see the world in a completely different way than their colorful cousins.
Researchers at the University of São Paulo (USP) in Brazil have discovered that the muscle regeneration promoted by aerobic exercise is mediated by changes in oxygen consumption by satellite cells, also known as skeletal muscle stem cells. The discovery is expected to be used to help people recover from injury and combat the loss of muscle mass associated with aging.
Irvine, Calif., Oct. 28, 2020 -- Testing a representative sample of Orange County residents for a wide range of coronavirus antibodies, University of California, Irvine researchers found that 11.5 percent of them have antibodies for COVID-19, in contrast to previous estimates of less than 2 percent.
Latino and low-income residents had the highest prevalence of SARS-CoV-02 antibodies with rates of 17 percent and 15 percent, respectively.
Announcing a new article publication for BIO Integration journal. In this review article the authors Chenxi Liu, Dian Jiao and Zhe Liu, from Tianjin University, Tianjin, China consider artificial intelligence (AI) aided disease prediction.
Artificial intelligence (AI) is widely used in clinical medicine and is increasingly applied to the fields of AI-aided image analysis, AI-aided lesion determination and AI-assisted healthcare management.
