"We know that without a vaccine we're going to be dealing with this virus for a while," said Johnese Spisso, president of UCLA Health, in an interview with Johannes Czernin. "We have to learn how to continue to provide health care as a health system with the presence of this emerging infectious disease." The interview is one of 5 new COVID-related articles and commentaries published in the June issue of The Journal of Nuclear Medicine (JNM).
Local governments are often innovators of public health policymaking--the first smoke-free air acts, menu labeling laws, and soda taxes were all implemented locally. However, states are increasingly limiting local control over public health issues by passing laws that overrule local regulations, a practice known as preemption.
CLEVELAND, Ohio (June 10, 2020)--Sex hormones influence the structure and function of the brain, but little is known about the effect of hormone therapies (HT) on changes in the brain during menopause. A new study shows smaller increases in structural brain changes related to aging were associated with hormone-level changes from transdermal estradiol or oral conjugated equine estrogen. Study results are published online in Menopause, the journal of The North American Menopause Society (NAMS).
Chicken is the most consumed protein in the United States. According to the National Chicken Council, the U.S. produced more than 9.2 billion broiler chickens in 2019. US consumers spent more than 95 billion dollars on chicken products.
All these broilers - chickens raised for meat - need millions of tons of litter, or bedding material. Reusing chicken litter can save costs. There exists some health and safety concerns though.
A new study shows that the environment in reused poultry litter can deter growth of pathogens like Salmonella.
ANN ARBOR, Mich. - For children and young adults with Crohn's disease, steroid-sparing therapies may help reduce the risk of developing a severe and common complication of the inflammatory bowel condition, a new study suggests.
About one in three people with Crohn's disease develop what's known as a perianal fistula, which can be painful, difficult to treat and may become debilitating - and they're much more common in children.
Scientists have expanded our understanding of potentially habitable planets orbiting distant stars by including a critical climate component - the presence of airborne dust.
The researchers suggest that planets with significant airborne dust - similar to the world portrayed in the classic sci-fi Dune - could be habitable over a greater range of distances from their parent star, therefore increasing the window for planets capable of sustaining life.
Inside our cells, DNA is tightly packed and spooled around proteins called histones. Packaging DNA in this way allows large amounts of genetic material to exist inside the cell in a final form called chromatin. Tiny enzymes modify the histones to make sure the genes that are part of the DNA can be accessed and precisely regulated. The result of this is proper gene expression and the production of proteins important for cell function and human health. When this process goes awry, the result can be diseases such as cancers.
Never before have we experienced social isolation on a massive scale as we have during the evolving COVID-19 pandemic. A new paper published in the journal Trends in Cognitive Sciences explores the wide-ranging, negative consequences that social isolation has on our psychological well-being and physical health, including decreased life span. The paper was co-authored by Associate Professor Danilo Bzdok (McGill University and Mila Quebec Artificial Intelligence Institute) and Emeritus Professor Robin Dunbar (University of Oxford).
"The smaller the particle, the bigger the hammer." This rule from particle physics, which looks inside the interior of atomic nuclei using gigantic accelerators, also applies to this research. In order to "X-ray" a two-atom molecule such as oxygen, an extremely powerful and ultra-short X-ray pulse is required. This was provided by the European XFEL which started operations in 2017 and is one of the the strongest X-ray source in the world
Researchers have confirmed that adapting splints in combination with the footwear used by disabled children to help them walk can decrease the energy they use by as much as 33%.
The Clinical Biomechanics team at Staffordshire University and the orthotics specialists from The Royal Wolverhampton NHS Trust examined the effectiveness of tuning the splint – footwear combination, using clinical trials with families in the West Midlands.
The oncogenic herpesvirus (HHV8 or KSHV) causes a cancer known as Kaposi's Sarcoma. An international team of scientists led by the University of Helsinki has discovered key factors that control the genome maintenance and replication of a virus responsible for lymphatic vascular cancer.
A new study from the University of Georgia has shown that exposure to a now-banned flame retardant can alter the genetic code in sperm, leading to major health defects in children of exposed parents.
Published recently in Scientific Reports, the study is the first to investigate how polybrominated biphenyl-153 (PBB153), the primary chemical component of the flame retardant FireMaster, impacts paternal reproduction.
Chronic bone and joint diseases, such as osteoporosis and rheumatoid arthritis, affect millions of people worldwide, particularly the elderly, degrading their quality of life. An important factor in both of these diseases is the excessive activity of bone-dissolving cells called osteoclasts. Osteoclasts are formed through differentiation from a certain type of immune cell called macrophage, after which they acquire their new role in the maintenance of bones and joints: breaking down bone tissue to allow osteoblasts-another type of cell-to repair and remodel the skeletal system.
A group on organic compounds under Professor Ivan Stoikov's guidance has been working on phenothiazine derivatives at Kazan Federal University since 2016.
Probably the most well-known derivative among the general public is methylene blue - a dye with antiseptic properties.
Although social distancing is crucial in thwarting the spread of COVID-19, isolation and the ensuing loneliness may be severely detrimental for older adults. A new study conducted by researchers at Bar-Ilan University and the University of Haifa has linked COVID-19-based loneliness in older adults with elevated psychiatric symptoms of anxiety, depression, and trauma symptoms that immediately follow exposure to trauma. The findings were recently published in the American Journal of Geriatric Psychiatry.
