NFL outperforms other blood tests to predict and diagnose traumatic brain injury
In a clinical trial of patients with rheumatoid arthritis, treatment with a drug called upadacitinib provided greater benefits than methotrexate, the most commonly used initial therapy for rheumatoid arthritis.
Non-invasive diagnostic procedures for suspected CHD: search reveals informative evidence
A study from the National Institutes of Health showed that neurofilament light chain (NfL) delivered superior diagnostic and prognostic performance as a blood biomarker for mild, moderate, and severe traumatic brain injury (TBI) when compared to blood proteins glial fibrillary acidic protein, tau, and ubiquitin c-terminal hydrolase-L1. The research was conducted by scientists at the NIH Clinical...
Numerous jobs linked to increased risk of knee reconstruction
Non-invasive diagnostic procedures for suspected CHD: search reveals informative evidence Informative study results are available on diagnostic procedures using computed tomography angiography (CTA) and magnetic resonance imaging (MRI) for suspected coronary heart disease (CHD).
Nurses and midwives take the lead in providing HIV services in Eastern and Southern Africa
A major review of knee osteoarthritis (OA), which can lead to knee surgery, pain and loss of mobility, reveals widespread risk of OA, demonstrating a need for prevention outside of traditional workplaces. It the biggest meta-analysis and systematic review of the potentially debilitating knee OA and the first systematic review into the association between job 'titles' and knee OA - finding...
Outdoor light linked with teens' sleep and mental health
"Nurse-initiated and managed antiretroviral therapy" (NIMART) is an innovative approach to making effective medications more accessible to people living with HIV (PLWH) in low-resource countries. A new study identifies challenges and opportunities to promoting nurse- and midwife-led HIV services in eastern and southern Africa, reports the July/August issue of The Journal of the Association of...
Physical activity of older people requires tailored monitoring
Research shows that adolescents who live in areas that have high levels of artificial light at night tend to get less sleep and are more likely to have a mood disorder relative to teens who live in areas with low levels of night-time light. The research was funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, and is published in JAMA...
Polynesians, Native Americans made contact before European arrival, genetic study finds
The ability to move about may deteriorate when ageing, a phenomenon which needs to be considered when assessing physical activity in older people.
Porous graphene ribbons doped with nitrogen for electronics and quantum computing
Through deep genetic analyses, Stanford Medicine scientists and their collaborators have found conclusive scientific evidence of contact between ancient Polynesians and Native Americans from the region that is now Colombia -- something that's been hotly contested in the historic and archaeological world for decades.
Preliminary study suggests tuberculosis vaccine may be limiting COVID-19 deaths
A team of physicists and chemists has produced the first porous graphene ribbons in which specific carbon atoms in the crystal lattice are replaced with nitrogen atoms. These ribbons have semiconducting properties that make them attractive for applications in electronics and quantum computing, as reported by researchers from the Universities of Basel, Bern, Lancaster and Warwick in the Journal of...
Programmable balloons pave the way for new shape-morphing devices
While a direct correlation between BCG vaccinations and a reduction in coronavirus mortalities still needs to be understood more fully, researchers hold hope that the BCG vaccine might be able to provide at least short-term protections against severe COVID-19, particularly for front-line medical workers or high-risk patients.
Protein involved in corn's water stress response discovered
A team of researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has designed materials that can control and mold a balloon into pre-programmed shapes. The system uses kirigami sheets -- thin sheets of material with periodic cuts -- embedded into an inflatable device.
Record efficiency for printed solar cells
The protein could help develop drought-resistant plant varieties and products that reduce losses related to climate change.
Reducing radioactive waste in processes to dismantle nuclear facilities
A new study reports the highest efficiency ever recorded for full roll-to-roll printed perovskite solar cells. It marks a key step towards cheaper and more efficient ways of generating solar energy.
Regulating the properties of MAPbBr3 single crystal via voltage and application
Margarita Herranz, professor of nuclear engineering at the UPV/EHU, leads one of the working groups in the Europe H2020 INSIDER project. The project aims to improve the management of contaminated materials by designing a methodology which allows the best scenarios in the dismantling, closing down and remediation of nuclear facilities to be specified and selected; the ultimate aim is for the waste...
Research advances understanding of how the brain focuses while ignoring distractions
Defect density is one of the most significant characteristics of perovskite single crystals (PSCs) that determines their optical and electrical properties, but few strategies are available to tune this property. Developing a technique for modifying the defect population of PSCs without requiring chemical additives is urgently need. Here, they demonstrate that voltage regulation engineering is...
Researchers find promising therapy to fight epidemic of liver disease
When trying to complete a task we are constantly bombarded by distracting stimuli. How does the brain filter out these distractions and enable us to focus on the task at hand? Psychologists at the University of California, Riverside, have made a discovery that could lead to an answer. Experimenting on mice, they located the precise spot in the brain where distracting stimuli are blocked.
Researchers find safeguards for quantum communications
In an effort to combat a growing worldwide epidemic of Nonalcoholic Fatty Liver Disease (NAFLD), scientists have discovered a new target and a new therapy that has shown promising results in preclinical mouse models, according to researchers at the University of Colorado Anschutz Medical Campus.
Researchers propose novel approach to limit organ damage for patients with severe COVID-19
Army researchers developed a new way to protect and safeguard quantum information, moving quantum networks a step closer to reality.
Researchers uncover a critical early step of the visual process
In a paper published in Cancer and Metastasis Reviews, a team of researchers from Beth Israel Deaconess Medical Center and Brigham and Women's Hospital propose that controlling the local and systemic inflammatory response in COVID-19 may be as important as anti-viral and other therapies.
Researchers work to better measure delirium severity in older patients
The key components of electrical connections between light receptors in the eye and the impact of these connections on the early steps of visual signal processing have been identified for the first time, according to research published today in Science Advances by The University of Texas Health Science Center at Houston (UTHealth).
Response to stimulation in IVF may predict longer term health risks
In a study published in Dementia and Geriatric Cognitive Disorder, researchers reported on their effort to improve and validate tools used to assess the severity of a condition called delirium, an acute confusional state often experienced by older hospitalized patients.
Restructuring of Medicaid reimbursement model reduces imaging, to the benefit of patients
A follow-up study of almost 20,000 young women who had a first cycle of IVF in Denmark between 1995 and 2014 indicates that those who responded poorly to treatment, with few eggs collected, are at a significantly increased risk of later age-related diseases.
Rock 'n' control
New research reveals a Medicaid payment model in Oregon leads to fewer traditional primary care services for patients, with the decrease focused entirely on imaging.
The goal of "Femtochemistry" is to film and control chemical reactions with short flashes of light. Using consecutive laser pulses, atomic bonds can be excited precisely and broken as desired. So far, this has been demonstrated for selected molecules. Researchers at the University of GÃ¶ttingen and the Max Planck Institute for Biophysical Chemistry have now succeeded in transferring this...
