Researchers have now identified the beneficial changes naturally occurring in the immune system during pregnancy. The findings, published in Journal of Neuroinflammation, can show the way to new treatments. Pregnancy is a very special condition from an immunological point of view. The immune system serves to defend us against foreign substances. However, although half of the genetic material of the foetus ...

People who adhere to global Cancer Prevention Recommendations are putting themselves at lower risk of developing the disease, new research confirms. Experts at Newcastle University have reviewed evidence of following the 2018 World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) lifestyle-based recommendations. The findings, published today in Cancer, revealed that adhering to a healthier lifestyle, including maintaining a healthy body weight and eating little red meat and processed meats such as bacon, helps ...

A research group led by Professor Hideki Fujiwara and Associate Professor Daisuke Sakamaki from the Graduate School of Science at Osaka Metropolitan University succeeded, for the first time, in synthesizing a new molecule using a novel combination of dynamic covalent chemistry, in which organic radicals couple and dissociate reversibly, and coordination chemistry, which binds radicals to metal ligands. The study shows that the two types of reactions work without inhibiting each other. “This research was based on a very simple idea of combining two types of reactions,” stated Professor Sakamaki. “However, it was not clear ...

Increased levels of Lipoprotein(a), a variant of ‘bad cholesterol’, in the bloodstream are a risk factor for recurrent coronary heart disease (CHD) in people aged 60 or over, according to the results of a new study which tracked the issue over the course of 16 years. The results, published today in Current Medical Research & Opinion, suggest that current cholesterol-lowering medications may not be effective at reducing the risk of recurrent CHD – such as a heart attack – due to elevated Lp(a). “This finding adds to growing evidence of a relationship between increased Lp(a) and the risk of recurrent CHD,” says lead author Associate Professor ...

Niigata, Japan - The Department of Neurology at Niigata University has developed a new in silico method for evaluating the pathogenicity of missense variants using AlphaFold2 (MOVA). Rare variants in the causative gene of ALS are present in 10-30% of sporadic ALS cases, which highlights the need for accurate and efficient pathogenicity prediction methods. To predict the pathogenicity of the variants, in silico analysis methods are commonly used. In some ALS causal genes, the mutations are concentrated in specific regions, and the accuracy of pathogenicity prediction can be improved by considering the positional information of the variants. ...

Niigata, Japan - The gold standard test for predicting the onset of diabetic kidney disease is albuminuria. However, detecting albuminuria alone has limited sensitivity and specificity in end-stage renal failure with a decreased estimated glomerular filtration rate. This is supported by several reports, which state that about half of the type 2 diabetes patients who developed kidney dysfunction showed no preceding albuminuria. In this study, the authors propose the possibility of diagnosing tubular abnormalities in diabetic kidney disease at an early stage and connecting them to treatment by combining the evaluation of sodium concentration using 23Na MRI ...

Older female mice had more immune cells entering areas of the body where they shouldn’t according to a new study, demonstrating that sex differences contribute to age-related inflammation that needs to be considered in future research.   In a paper published in Journal of Leukocyte Biology today (Tuesday 13 June), at team of researchers led by Dr Myriam Chimen from the University of Birmingham have found that age significantly increases the number of immune cells entering the sack that holds major organs (peritoneal cavity) in female mice, when compared to young mice or older male mice.   The findings support previous studies that suggest ...

Peer-reviewed / Randomised Controlled Trial / People Study of healthy US adults found that a single dose of the VLA1553 vaccine candidate was generally safe, well tolerated and provokes an immune response. After a single vaccination, the vaccine produced neutralizing antibody levels which are thought to protect against chikungunya disease in 99% (263/266) of participants. Antibody levels declined 28 days after vaccination, but seroprotection persisted in more than 96% (233/242) participants after six months. Most adverse events were moderate or mild and the authors say its safety profile is similar to other licensed vaccines The VLA1553 vaccine candidate ...

Glasgow, UK:  The informed consent process in biomedical research is biased towards people who can meet with clinical study staff during the working day.

Professor Eric Vilain, from the Department of Paediatrics, University of California, Irvine, USA, will tell the European Society of Human Genetics annual conference today (Tuesday 13 June) how results from his team’s study of the use of a chatbot (GIA – ‘Genetics Information Assistant’ ...

Weight and body mass index (BMI) policies introduced by NHS commissioning groups in England are inappropriate and worsening health inequalities, according to a new study published in BMC Medicine today [13 June] that analysed nearly 490,000 hip surgeries. With one in ten people likely to need a joint replacement in their lifetime, many thousands of patients are directly affected by these policies. Rules implemented by NHS clinical commissioning groups (CCGs) across England to change the access to hip and knee replacement surgery for patients who are overweight or obese have been in effect for over ten years. ...

In a world of continuously warmer temperatures, a growing consensus demands that energy sources have zero, or next-to-zero, carbon emissions. That means growing beyond coal, oil, and natural gas by getting more energy from renewable sources. One of the most promising renewable energy carriers is clean hydrogen, which is produced without fossil fuels. It’s a promising idea because the most abundant element in the universe is hydrogen, found in 75 percent of all matter. Moreover, a hydrogen molecule has two paired atoms—Gemini twins that are both non-toxic and highly combustible. Hydrogen’s combustive potential ...

A decade after UC San Francisco scientists identified an over-the-counter antihistamine as a treatment for multiple sclerosis, researchers have developed an approach to measure the drug’s effectiveness in repairing the brain, making it possible to also assess future therapies for the devastating disorder.  The researchers, led by physician-scientist Ari Green, MD, who together with neuroscientist Jonah Chan, PhD, first identified clemastine as a potential MS therapy, used MRI scans to study the drug’s impact on the brain of 50 participants in a clinical study.  In MS, patients lose myelin, the protective insulation around ...

As the world struggles for sustainability in the face of climate change, wildfire smoke becomes a lesson in how people can become victims far from the root of a problem and far from their control. In this month’s open access National Science Review, Jianguo “Jack” Liu, MSU Rachel Carson Chair in Sustainability, makes a case for the world to shake off the constraints of traditional governance, which tends to address issues in one place without considering how people or ecologies near and far might be impacted. Justice at a global scale can be threatened when natural events or human decisions in one part of the world to protect, reroute, ...

New findings from a project led by researchers at Dartmouth’s Geisel School of Medicine in collaboration with the National Cancer Institute (NCI) and published in the journal JAMA Network Open, show the dramatic impact that smoking status has on mortality and more accurately predict the risk of dying from cancer and other diseases.   “Historically, mortality risk has often been presented by age, sex, and race but it rarely has accounted for smoking status—a major risk factor for many causes of death,” says lead author Steven Woloshin, MD, MS, a professor of ...
