Researchers of Sechenov University together with their colleagues from Australia used the microfluidics technology to develop a device able to isolate cancer cells from urine of patients with prostate cancer. The study showed high sensitivity and specificity of the new method in diagnosing prostate cancer. The results obtained were published in Cancers.
Bone marrow plasma cells produce antibodies. These comprise two long and two short protein chains. The pathological proliferation of plasma cells can lead to an overproduction of the short chains. These associate to fibrils and deposit in organs. The result is fatal organ failure. A research team from the Technical University of Munich (TUM) and Heidelberg University has now identified the mutation behind the disease in a patient.
Many surveys of American adults have revealed that they worry about political issues and are concerned for the future of the United States. But what about children and teenagers?
Sometimes in a glass of wine, liquid can appear to climb the side of the glass, forming "tears" that slide back down into the wine. Now, researchers have created a new hydrodynamic model to better account for wine tears' fluid dynamics. The model shows that a combination of fluid physics, including gravity, surface tension, and changes in surface tension induced by alcohol evaporation, can lead to complex fluid structures resulting in wine tears.
A team of researchers from the University of Georgia and San Diego State University has found that the practice of feeding wildlife could be more detrimental to animals than previously thought.
In a paper published recently in Nature Scientific Reports, researchers found that feeding wildlife can disrupt the social lives of animal communities, which they discovered by observing and documenting the behavior of moor macaque monkeys along a wooded roadway on the island of Sulawesi in eastern Indonesia.
Researchers at UC have discovered a previously unknown mechanism that could explain the reason behind decreased immune function in cancer patients and could be a new therapeutic target for immunotherapy for those with head and neck cancers.
The authors share these findings in an article published in the journal Frontiers in Pharmacology.
Immunotherapy is a type of cancer treatment that boosts the body's natural defenses to fight cancer.
More than half of the world's population faces a looming threat to the quality and availability of their drinking water because climate change and urbanisation are expected to cause an increase in groundwater organic carbon, a new UNSW study has found.
The research, published in Nature Communications overnight, examined the largest global dataset of 9404 published and unpublished groundwater dissolved organic carbon (DOC) concentrations from aquifers in 32 countries across six continents.
Silicon is abundant in nature with high theoretical capacity (4200 mAh g-1), making it an ideal anode material for improving the energy density of dual-ion batteries (DIBs). However, its application in DIBs has been restricted by the large volume expansion problem (>300%).
Rigid contacts between silicon and current collectors, commonly made with metal foils, lead to significant interfacial stress. As a consequence, interface cracking and even exfoliation of active materials occur resulting in suboptima cycling performance.
Faced with a gritty landscape of metal fences, concrete walls and asphalt pavement, city lizards in Puerto Rico rapidly and repeatedly evolved better tolerance for heat than their forest counterparts, according to new research from Washington University in St. Louis and the University of California, Los Angeles.
Studies that delve into how animals adapt in urban environments are still relatively rare. But anoles are becoming a model system for urban evolutionary research.
The natural coastal defenses provided by mangrove forests reduce annual flooding significantly in critical hotspots around the world. Without mangroves, flood damages would increase by more than $65 billion annually, and 15 million more people would be flooded, according to a new study published March 10 in Scientific Reports.
"Mangroves provide incredibly effective natural defenses, reducing flood risk and damages," said Pelayo Menéndez, a postdoctoral fellow in the Institute of Marine Sciences at UC Santa Cruz and first author of the paper.
With the spread of electric vehicles, interest in "high capacity batteries" is high. Lithium metal batteries, which use lithium metal on their anodes, are also drawing attention in this context. However, the problem is that the stability of the lithium metal is too large and the stability is low. The technology that solved this by the "electrolyte" in battery came out.
Philadelphia, March 10, 2020 - An increased awareness of concussion risks in young athletes has prompted researchers to use a variety of head impact sensors to measure frequency and severity of impacts during sports. A new study from Children's Hospital of Philadelphia (CHOP) shows these head sensors can record a large number of false positive impacts during real game play. The CHOP team's study emphasizes that an extra step to video-confirm the sensor data is essential for research and for use of this data in injury prevention strategies for player safety.
COLUMBUS, Ohio - People who rate themselves as highly knowledgeable about a new infectious disease threat could also be more likely to believe they don't know enough, a new study suggests.
In the case of this study, the infectious disease threat was the Zika virus. But the authors of the new study, published recently in the journal Risk Analysis, say the results could apply to the recent novel coronavirus (COVID-19) outbreak.
From the headphones we use to listen to our favorite songs or podcasts, to sonic camouflage employed by submarines, how we transmit and experience sound is an essential part of how we engage with our surrounding world. Acoustic metamaterials are materials designed to control, direct and manipulate soundwaves as they pass through different mediums. As such, they can be designed and inserted into a structure to dampen or transmit sound.
Method yielding high rate of D-lactate using cyanobacteria could revolutionize bioplastic production
A Kobe University led research team has illuminated the mechanism by which cyanobacteria (Synechocystis sp. PCC 6803) produces D-lactate, showing that malic enzyme facilitates this production. Subsequently, they succeeded in producing the world's highest rate (26.6g/L) of D-lactate directly from CO2 and light by modifying the D-lactate synthesis pathway using genetic engineering.
