Combination of easily accessible tests can enable early, reliable diagnosis of Alzheimers disease Researchers at Lund University in Sweden have developed an algorithm that combines data from a simple blood test and brief memory tests, to predict with great accuracy who will develop Alzheimers disease in the future. The findings are published in Nature Medicine. Approximately 20-30% of patients with Alzheimers disease are wrongly diagnosed within specialist healthcare, and diagnostic work-up is ...

Chemical Reactions on Nanoparticle Surface are More Complex than Thought Written by AZoNanoMay 24 2021 A majority of commercially available chemicals are created with the help of catalysts. Generally, such catalysts contain very small metal nanoparticles that are positioned on an oxidic support. (a) Modern catalysts consist of nanoparticles. (b) A Rhodium tip as a model for a nanoparticle. (c) Tracing a chemical reaction in real time with a field emission microscope. (d) At low temperatures, di...

The novel coronavirus responsible for COVID-19 could cause no more than common cold-like coughs and sniffles within the next decade, according to a study. The research, published in the journal Viruses, makes this likely prediction based on mathematical models that incorporate lessons learned from the current pandemic on how our bodys immunity changes over time. "This shows a possible future that has not yet been fully addressed," said Fred Adler, a professor of mathematics and biological sc...

Solar Geoengineering can Mitigate Effects of Global Warming on Rainfed Crops Written by AZoCleantechMay 21 2021 Solar geoengineering, which means releasing aerosols into the air to reflect solar light and cut down global warming, is not a complete solution for climate change but it might be one of many tools to control climate risks. Image Credit: shutterstock.com/oticki The potential of solar geoengineering to decrease physical climate changes was investigated by a growing body of research. Ho...

Study confirms that human endocrine system is strongly involved in SARS-Cov-2 infection The endocrine system is strongly involved in SARS-Cov-2 infection - so much so that evidence of an "endocrine phenotype" of COVID-19 has emerged, according to a statement by the European Society of Endocrinology (ESE) published in the journal Endocrine in April 2021. Leading endocrinology researchers looked into the evidence that has accumulated over the past year since the pandemic emerged, and consistentl...

Highly Sensitive Seismic Instruments Enable Groundwater Monitoring Written by AZoSensorsMay 20 2021 Water in high-mountain areas has a number of features. Frozen in the ground, water is similar to a cement foundation that maintains the stability of slopes. The catchment area of Bhote Koshi River lies in the bordering region between Nepal and China. Image Credit: Luc Illien/GFZ. During the melt season, snow and glacial ice sustain the rivers and, thus, the foothills with water for agriculture an...

Scientists have developed a mathematical model that predicts how the number and effects of bacterial mutations leading to drug resistance will influence the success of antibiotic treatments.

Covid-19 patients show reduced gray matter volume in the brain Covid-19 patients who receive oxygen therapy or experience fever show reduced gray matter volume in the frontal-temporal network of the brain, according to a new study led by researchers at Georgia State University and the Georgia Institute of Technology. The study found lower gray matter volume in this brain region was associated with a higher level of disability among Covid-19 patients, even six months after hospital discharge. Gr...

SFHN clinicians support the use of telehealth services for outpatient primary care As state and federal authorities decide whether to continue reimbursing for telehealth services that were suddenly adopted last spring in response to the coronavirus pandemic, a new study out of UC San Francisco has found that clinicians in the San Francisco Health Network (SFHN) overwhelmingly support using these services for outpatient primary care and specialty care visits. The results surprised the research t...

Researchers discover new binding sites for active agents on cell cytoskeleton Through a unique combination of computer simulations and laboratory experiments, researchers at the Paul Scherrer Institute PSI have discovered new binding sites for active agents - against cancer, for example - on a vital protein of the cell cytoskeleton. Eleven of the sites hadnt been known before. The study appears today in the journal Angewandte Chemie International Edition. The protein tubulin is an essential bu...
