Antibodies that exist in the joints before the onset of rheumatoid arthritis can cause pain even in the absence of arthritis, researchers from Karolinska Institutet in Sweden report. The researchers believe that the finding, which is published in the Journal of Experimental Medicine, can represent a general mechanism in autoimmunity and that the results can facilitate the development of new ways of reducing non-inflammatory pain caused by rheumatoid arthritis and other autoimmune diseases.
A new white paper from the Johns Hopkins Center for Gun Policy and Research at the Johns Hopkins Bloomberg School of Public Health concludes that of the approaches used by states to screen out prohibited individuals from owning firearms, only purchaser licensing has been shown to reduce gun homicides and suicides. Purchaser licensing is currently used by nine states and Washington, D.C.
Food's texture affects whether it is eaten, liked or rejected, according to Penn State researchers, who say some people are better at detecting even minor differences in consistency because their tongues can perceive particle sizes.
The research published in Nature Communications set out to answer a simple question - how do nanoparticles melt? Although this question has been a focus of researchers for the past century, it still is an open problem - initial theoretical models describing melting date from around 100 years, and even the most relevant models being some 50 years old.
Research conducted by the University of Kent has suggested that the sexual selection hypothesis for infanticide may be the key driver for the high rate of infant killings among a community of chimpanzees in Uganda.
Led by PhD student Adriana Lowe and Dr Nicholas Newton-Fisher from Kent's Living Primates Group, the research team analysed the records of infanticides and failed attempts at infanticide over a 24-year period in the Sonso community of chimpanzees in the Budongo Forest.
WASHINGTON - A centralized, consistently reported system of indicators of educational equity is needed to bring attention to disparities in the U.S. education system, says a new report by the National Academies of Sciences, Engineering, and Medicine.
A mite that spreads a dangerous virus among honeybees also plays an indirect role in infecting wild bumblebees, new research shows.
The Varroa destructor mite lives on honeybees and can spread deformed wing virus (DWV) throughout the hive.
The mite has emerged as a parasite of Western honeybees, after switching from its original host, the Asian honeybee at the beginning of the last century. It has since spread globally through the man-made movement of infested honeybee hives and has turned into a viral vector.
A new study finds substantial variation in the prevalence of triple-negative breast cancer among black women with breast cancer by birthplace in the United States. The prevalence of triple-negative breast cancer was highest among U.S.-born and Western-African-born black women, followed by Caribbean-born, and Eastern-African-born black women. The study is published in the journal Cancer and its findings suggests that the typical notion of higher proportional burden of triple-negative breast cancer among black women is not generalizable to all women of African descent.
Philadelphia, June 13, 2019 - Antimalarial drugs appear to follow a typical pattern, with early effectiveness eventually limited by the emergence of drug resistance. A report in the Journal of Molecular Diagnostics, published by Elsevier, describes a new assay using whole blood that simplifies the genetic analysis of malarial parasites by completely eliminating processing steps.
(BOSTON) -- Like airport security barriers that either clear authorized travelers or block unauthorized travelers and their luggage from accessing central operation areas, the blood-brain-barrier (BBB) tightly controls the transport of essential nutrients and energy metabolites into the brain and staves off unwanted substances circulating in the blood stream.
BEER-SHEVA, Israel...June 13, 2019 - A research team led by Ben-Gurion University of the Negev (BGU) Prof. Iris Shai has published a significant long-term study on the impact of Mediterranean and low-carb diets and exercise, measuring their impact with magnetic resonance imaging (MRI) technology to map body fat.
BOSTON (June 13, 2019)--Low levels of circulating vitamin K are linked to increased risk of mobility limitation and disability in older adults, identifying a new factor to consider for maintaining mobility and independence in older age, according to a study led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University.
Madrid, Spain, 13 June 2019: The results of a study presented today at the Annual European Congress of Rheumatology (EULAR 2019), jointly organised with the Paediatric Rheumatology Society (PReS), demonstrate no vaccine infections, and no disease flare, in the 234 rheumatic patients who received live-attenuated booster vaccination while taking immune suppressing therapies.1
Madrid, Spain, 13 June 2019: The results of a study presented today at the Annual European Congress of Rheumatology (EULAR 2019) finds the risk of bone mineral density (BMD) loss after denosumab discontinuation is associated with younger age, high bone turnover markers, and not receiving the bisphosphonate, zoledronate, prior to initiation of denosumab.1
BOSTON -- (EUREKALERT!) -- Alexion Pharmaceuticals, Inc. today announced the first conference presentation of the topline Phase 3 data for ULTOMIRIS® (ravulizumab), the first and only long-acting C5 complement inhibitor administered every eight weeks, in adult patients with atypical hemolytic syndrome (aHUS).
