Durham, NC - Mid-term results of the first clinical trial designed specifically to evaluate the safety and effectiveness of two cell therapies that are showing early promise in treating angiitis-induced critical limb ischemia were released today in STEM CELLS Translational Medicine. The study, by researchers at Zhongshan Hospital/Fudan University in Shanghai, compared how transplantation of peripheral blood mononuclear cells fared versus transplantation of purified CD34+ cells in treating this condition.
Inspired by the color-changing skin of cuttlefish, octopuses and squids, Rutgers engineers have created a 3D-printed smart gel that changes shape when exposed to light, becomes "artificial muscle" and may lead to new military camouflage, soft robotics and flexible displays.
The engineers also developed a 3D-printed stretchy material that can reveal colors when light changes, according to their study in the journal ACS Applied Materials & Interfaces.
Researchers from Tokyo Medical and Dental University (TMDU) describe an endoscopic modality for detecting upper gastrointestinal tract neoplasms by Linked Color Imaging that innovatively mixes light of different wavelengths to better depict mucosal changes
An imbalance of the body's oxygen producing free radicals and its antioxidant cells could be the reason why gum disease and chronic kidney disease affect each other, a new study led by the University of Birmingham has found.
Periodontitis - or gum disease - is a common, inflammatory disease which causes bleeding gums, wobbly or drifting teeth and can eventually result in tooth loss.
Practicing gratitude and looking to the future will help safeguard our mental wellbeing during Covid-19 lockdowns, a new study in the Journal of Positive Psychology reports.
In the first study of its kind, researchers from the University of Surrey investigated the effectiveness of three psychological interventions -- nostalgia, a sentimentality for the past; gratitude, recognising the good things currently in our life; and best possible self, thinking about positive elements of the future -- and how they each affect wellbeing during lockdowns.
In a joint collaboration, Danish and German researchers have characterized a cellular activity that protects our cells from potentially toxic by-products of gene expression. This activity is central for the ability of multicellular organisms to uphold a robust evolutionary 'reservoir' of gene products.
Manufacturing processes need quality control systems in order to ensure proper assembly of functional products. Moreover, space-consuming, and perhaps even toxic, by-products of such processes need to be properly discarded or recycled by efficient waste handling systems.
Assessing the ability of unresponsive patients with severe brain injury to understand what is being said to them could yield important insights into how they might recover, according to new research.
A team at the University of Birmingham has shown that responses to speech can be measured using electroencephalography, a non-invasive technique used to record electrical signals in the brain. The strength of these responses can be used to provide an accurate prognosis that can help clinicians make the most effective treatment decisions.
BOSTON - A long-running debate over how an important gene-silencing protein identifies its targets has been resolved by researchers at Massachusetts General Hospital (MGH). Their findings, reported in Nature Structural and Molecular Biology, also explain certain mysteries about the behavior of this protein, known as Polycomb repressive complex 2 (PRC2).
If you've ever had a bad case of jet lag, you know how a disruption to your body's circadian rhythm makes it difficult to function. Molecular circadian "clocks" exist in cells throughout the body, governing more than just sleep and wake cycles - they are crucial to many aspects of human health. For more than a decade researchers have been trying to figure out what makes them tick, in search of new insights into diseases like Alzheimer's, cancer and diabetes.
New Rochelle, NY, January 4, 2021--Crop plants and animals can be infected by bacterial pathogens that reduce yield, cause food wastage, and carry human pathogens that spread disease on consumption. Bacteriophage can play an important role in microbial control, according to a new Special Issue on Agriculture and Aquaculture published in the peer-reviewed journal PHAGE: Therapy, Applications, and Research.

A new study out of the University of Chicago Medicine following young adult drinkers for 10 years has found that individuals who reported the highest sensitivity to alcohol's pleasurable and rewarding effects at the start of the trial were more likely to develop an alcohol use disorder (AUD) over the course of the study.
Bird diets provide a real treasure for research into the distribution and conservation of their prey, such as overlooked and rare bush-cricket species, point out scientists after studying the diet of the Eurasian Eagle Owl (Bubo bubo) in southeastern Bulgaria.
December 31, 2020 - Data on COVID-19 transmission among Chicago youth - particularly in the city's extensive network of Catholic schools - supports a strategy for gradual reopening of the city's public school system, according to a report in the Journal of Public Health Management and Practice.
CORVALLIS, Ore. -- A pair of recent studies from Oregon State University found that Oregon's Medicaid expansion in 2014 has led to increased prenatal care among low-income women, as well as improved health outcomes for newborn babies.
In the three years after the expansion, one study found that Oregon saw an almost 2 percentage point increase in first trimester prenatal care utilization, relative to 18% of the pre-expansion population who lacked any access to prenatal care in the earlier stages of pregnancy.
By applying statistical geometry to analyzing urban road networks, KAUST researchers have advanced understanding of how wireless charging roads might influence driver behavior and city planning in a future where electric vehicles (EVs) dominate the car market.
