NEW YORK - October 14, 2020 - An individual patient data pooled analysis comparing the use of bivalirudin versus heparin in heart attack patients undergoing percutaneous coronary intervention (PCI) found that bivalirudin use was associated with similar overall rates of 30-day mortality across all heart attack patients, but lower rates of serious bleeding events. Moreover, mortality was reduced in patients with ST-segment elevation myocardial infarction (STEMI) who were treated with a post-PCI bivalirudin infusion.
During the early 1800s, the first spectrometer was developed by spreading different colors of sunlight onto a screen. It was later noticed that certain dark bands in the solar spectrum, known as Fraunhofer lines, are associated with chemical elements in the solar atmosphere. Since then, scientists have applied spectroscopy to many different fields including astronomy, medicine, agriculture, chemistry, and security.
Since the discovery of the quantum Hall effect, topological phases of electrons have become a major research area in condensed matter physics. Many topological phases are predicted in lattices with specific engineering of electronic hopping between lattice sites. Unfortunately, the distance between neighboring sites in natural lattices (crystals) is on the order of a billionth of a meter, which makes such engineering extremely difficult. On the other hand, the photonic crystals have a much larger scale.
NEW YORK - October 14, 2020 - New data from the PROSPECT II study shows that NIRS-IVUS intracoronary imaging can help identify angiographically non-obstructive lesions with high-risk characteristics for future adverse cardiac outcomes.
Findings were reported today at TCT Connect, the 32nd annual scientific symposium of the Cardiovascular Research Foundation (CRF). TCT is the world's premier educational meeting specializing in interventional cardiovascular medicine.
Laser technology has been used to measure the volume and biomass of giant Californian redwood trees for the first time, records a new study by UCL researchers.
The technique, published in Scientific Reports, offers unprecedented insights into the 3D structure of trees, helping scientists to estimate how much carbon they absorb and how they might respond to climate change.
PHILADELPHIA--An electronic nudge to clinicians--triggered by an algorithm that used machine learning methods to flag patients with cancer who would most benefit from a conversation around end-of-life goals--tripled the rate of those discussions, according to a new prospective, randomized study of nearly 15,000 patients from Penn Medicine and published today in JAMA Oncology.
Monash University engineers have demonstrated improvements in the fatigue life of high strength aluminium alloys by 25 times - a significant outcome for the global transport industry.
Aluminium alloys are light, non-magnetic and have great corrosion resistance. But, their fatigue properties are poor.
Researchers were able to make aluminium alloy microstructures that can heal while in operation.
Imagine going to a café you have never been to. You will remember this new environment, but when you visit it again and again fewer new memories about the environment will be formed, only the things that changed will be really memorable. How this long-term memory are regulated is still not fully understood. Ryuichi Shigemoto from the Institute of Science and Technology Austria (IST Austria) in cooperation with researchers from Aarhus University and the National Institute for Physiological Sciences in Japan now have uncovered a new keystone in the formation of memories.
"Clusters form big families of stars that can stay together for large parts of their lifetime. Today, we know of roughly a few thousand star clusters in the Milky Way, but we only recognize them because of their prominent appearance as rich and tight groups of stars. Given enough time, stars tend to leave their cradle and find themselves surrounded by countless strangers, thereby becoming indistinguishable from their neighbours and hard to identify" says Stefan Meingast, lead author of the paper published in Astronomy & Astrophysics.
A joint research team led by Prof. WANG Hui and Prof. LIN Wenchu from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science developed a synthesis of metal-free multifunctional therapeutic reagents, called graphitic carbon nitride quantum dots embedded in carbon nanosheets (CNQD-CN), via a one-step hydrothermal treatment.
Metal-free multifunctional nanomaterials have broad application prospects in integrated cancer diagnosis and treatment.
The team took an organic solvent (formamide) as the carbon and nitrogen source and then developed CNQD-CN.
Using a brain-inspired approach, scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a way for robots to have the artificial intelligence (AI) to recognise pain and to self-repair when damaged.
The system has AI-enabled sensor nodes to process and respond to 'pain' arising from pressure exerted by a physical force. The system also allows the robot to detect and repair its own damage when minorly 'injured', without the need for human intervention.
The spring of 2018 was the hottest on record since 1951 over eastern China. This record-breaking temperature event caused drought, warm winds and serious impacts on agriculture, plant phenology, electricity transmission systems and human health. Both human-induced global warming and anomalous circulation increased the chance of this extreme high-temperature event, according to a new attribution analysis by Dr. Chunhui Lu and Prof. Ying Sun of China Meteorological Administration and their collaborators from the UK Met Office.
The processes our brains use to avoid harming other people are automatic and reflexive - and quite different from those used when avoiding harm to ourselves, according to new research.
A team based in the Universities of Birmingham and Oxford in the UK and Yale University in the US investigated the different approaches to avoiding pain for the first time. They found that when learning to avoid harming ourselves, our decision-making tends to be more forward-looking and deliberative.
Researchers at the Laboratory of Organic Electronics, Linköping University, have for the first time demonstrated an organic battery. It is of a type known as a "redox flow battery", with a large capacity that can be used to store energy from wind turbines and solar cells, and as a power bank for cars.
In the search for solutions to ever-worsening environmental problems, such as the depletion of fossil fuels and climate change, many have turned to the potential of thermoelectric materials to generate power. These materials exhibit what is known as the thermoelectric effect, which creates a voltage difference when there is a temperature gradient between the material's sides.
