Researchers discover potential new approach to treating psoriatic joint inflammation

Alexandria, Va., USA -- Dental care professionals are thought to be at enhanced risk of occupational exposure to SARS-CoV-2, but robust data to support this is lacking. The study "COVID-19: Seroprevalence and Vaccine Responses in UK Dental Care Professionals," published in the Journal of Dental Research (JDR), provides a longitudinal analysis of antibodies to SARS-CoV-2 spike glycoprotein, including early analysis of the impact of vaccination on the immune response. In June 2020, I,507 West Midlands dental care professionals were recruited to test for baseline seroprevalence, or the proportion of the population that have circulating antibodies to SARS-CoV-2, indicating prior ...

Viruses can spread not only via droplets or aerosols like the new coronavirus, but in water, too. In fact, some potentially dangerous pathogens of gastrointestinal diseases are water-borne viruses. To date, such viruses have been removed from water using nanofiltration or reverse osmosis, but at high cost and severe impact on the environment. For example, nanofilters for viruses are made of petroleum-based raw materials, while reverse osmosis requires a relatively large amount of energy. Environmentally friendly membrane developed Now an international team of researchers led by Raffaele ...

People in both the United States and China who think others are being duped by online misinformation about COVID-19 are also more likely to support corporate and political efforts to address that misinformation, according to a new study. The study suggests negative emotions may also play a role in the U.S. - but not in China. "A lot of misinformation has been shared online over the course of the COVID-19 pandemic, and we had a range of questions about how people are responding to this misinformation," says Yang Cheng, co-lead author of the study and an assistant professor of communication at North Carolina State University. "How do different emotions influence ...

Japanese researchers have developed and tested a prototype device -- wearable on the fingertips -- that incorporates the concept of 'light touch' to enhance the sense of balance. If widely implemented, the device should significantly reduce incidence of falls amongst seniors. The findings are published in the journal Scientific Reports on April 1. As we age, our sense of balance can become impaired. The resulting increase in postural sway in turn increases the risk of falls and consequent injuries. Meanwhile, older people make up a large and increasing proportion of the population in highly developed countries. ...

Research involving scientists from the University of A Coruña has succeeded in sequencing the oldest mitochondrial genome of the immediate ancestor of modern cows that has been analysed to date. The remains, some 9,000 years old, were found next to a woman. Why were they with her if cattle had not yet been domesticated? Do they belong to ancestors of today's Iberian cows? Humans have maintained a very close relationship with aurochs (Bos primigenius) since their beginnings, first by hunting them and then by breeding and selecting them. This extinct species of mammal is little known in the Peninsula because its skeletal remains are difficult to distinguish from bison. In fact, there have been references to the presence of "large bovids" in many sites because ...

Interactions in the network can lower the critical temperature thresholds beyond which individual tipping elements begin destabilizing on the long-run, according to the study - the risk already increases significantly for warming of 1.5°C to 2°C, hence within the temperature range of the Paris Agreement. "We provide a risk analysis, not a prediction, yet our findings still raise concern," says Ricarda Winkelmann, Lead of FutureLab on Earth Resilience in the Anthropocene at the Potsdam Institute for Climate Impact Research (PIK). "We find that the interaction of these four tipping elements can make them overall more vulnerable due to mutual destabilization on the long-run. The feedbacks between them tend to lower the critical temperature ...

A new study looking at the benefits of good farmer seed production suggests women need more support to participate in contract farming - to the same extent as their male counterparts - and have more equality along the whole food value chain. The CABI-led research - which sought to assess the benefits of good farmer seed production through a case study of the Good Seed Initiative in Tanzania - reveals that while around 70% of the labour to grow African Indigenous Vegetables (AIVs) is provided by women only 10 to 30% are contract farmers who own the fields, make decisions on sales and control revenues. The paper, led by Dr Monica Kansiime ...

Philadelphia, June 3, 2021 - Researchers at Children's Hospital of Philadelphia (CHOP) have demonstrated how to use standardized reporting of clinical data for seizures caused by a variety of neurological disorders, providing fundamental baseline information that can determine what methods work best for keeping seizures under control. The findings were published today in the journal Epilepsia. In order to make improvements in epilepsy care, clinicians need a reliable and efficient method to measure outcomes. While Electronic Medical Records (EMR) are being used more frequently for research and quality improvement, important epilepsy outcome measures such ...

MUSC Hollings Cancer Center researchers are finding solutions to the aging-related changes that reduce anti-cancer immunity. Besim Ogretmen, Ph.D., and colleagues found a novel link between aging, metabolism and anti-cancer T-cell function. Their work, published in Cell Reports, sheds light on an important pathway that cannot be ignored during cancer treatment. Two broad questions in cancer research are: How can cancer treatments be improved, and what is the link between cancer and aging? "We know that the protective T-cell response deteriorates with age. Mitochondrial function is now thought to be one of the central regulators of the aging process. Our experiments connected the dots with what was previously shown and highlighted some ...

Thursday, June 3, 2021, CLEVELAND: A Cleveland Clinic study shows that survivors of COVID-19 who have moderate or severe obesity may have a greater risk of experiencing long-term consequences of the disease, compared with patients who do not have obesity. The study was recently published online in the journal of Diabetes, Obesity and Metabolism. Multiple studies have identified obesity as a risk factor for developing a severe form of COVID-19 that may require hospital admission, intensive care, and ventilator support in the early phase of the disease. Obesity, which is a complex disease caused by multiple factors, is associated with an increased risk for cardiovascular ...
