Neutralizing monoclonal antibody use and COVID-19 infection outcomes
2023-04-24
About The Study: In this study that included 167,000 non-hospitalized patients, neutralizing monoclonal antibody (nMAb) treatment for COVID-19 was safe and associated with reductions in emergency department visits, hospitalization, and death, although it was not associated with reduced risk of hospitalization during the Omicron BA.1 epoch. These findings suggest that targeted risk stratification strategies may help optimize future nMAb treatment decisions.
Authors: Brian Anderson, M.D., of the MITRE Corporation in Bedford, Massachusetts, is the corresponding author.

New insights on the risk for atrial fibrillation in children and young adults
2023-04-24
Researchers at Karolinska Institutet in Sweden have investigated how preterm birth and foetal growth are related to the risk of atrial fibrillation up to middle-age. The study, which is published in JAMA Pediatrics, shows that being born preterm or large for gestational age was associated with increased risks of atrial fibrillation later in life. Being small for gestational age at birth was only associated with an increased risk of atrial fibrillation up to the age of 18.
The incidence of atrial fibrillation in the young has increased over the past few decades, from low levels.
“Atrial fibrillation at a young age may involve a heavy socioeconomic burden for the affected ...
Vaccine printer could help vaccines reach more people
2023-04-24
CAMBRIDGE, MA -- Getting vaccines to people who need them isn’t always easy. Many vaccines require cold storage, making it difficult to ship them to remote areas that don’t have the necessary infrastructure.
MIT researchers have come up with a possible solution to this problem: a mobile vaccine printer that could be scaled up to produce hundreds of vaccine doses in a day. This kind of printer, which can fit on a tabletop, could be deployed anywhere vaccines are needed, the researchers say.
“We could someday ...

Researchers ID novel treatment pathway for deadly pancreatic cancers
2023-04-24
Researchers at the Johns Hopkins Kimmel Cancer Center identified a novel cell signaling pathway that potentially could be targeted in therapy for patients with aggressive pancreatic cancers.
In laboratory studies with human pancreatic cancer cell lines and genetically engineered mouse models of pancreatic cancer, the investigators discovered that the High Mobility Group A1 (HMGA1) protein functions as a “molecular switch” that “flips on” genes required by tumor cells to grow in an uncontrolled fashion and form invasive tumors. One of these genes activated ...
Maternal and early-life high-fat diets result in a taste for salty food
2023-04-24
Tokyo, Japan – We are all aware of the importance of eating healthy food, especially during pregnancy. A high-fat diet has dramatic consequences on the metabolism. It can lead to obesity, diabetes, chronic liver disease, and possibly cancer. Previous works have demonstrated that eating high amounts of fat during pregnancy affects the taste preference and metabolism in offspring. In most households, children and parents eat the same food. In other words, mums eating a high-fat diet will likely feed their children fatty foods. What are the consequences of maternal ...

A panoramic view on lithium-mediated electrochemical dinitrogen reduction reaction
2023-04-24
The Haber-Bosch process is the industrial approach for NH3 production today, which must be operated at energy-intensive high temperatures and pressures. The reduction of dinitrogen (N2) by electrocatalysis offers an alternative way for NH3 production at ambient conditions and a variety of electrocatalysts have been studied over the past few years. However, even the best catalytic system reported could only get unsatisfied performance (such as the selectivity and production rate of NH3) due to the ...
Unveiling a fast and efficient method for detecting microRNAs
2023-04-24
In the early 1990s, scientists who were studying the development of a roundworm identified a small RNA molecule that regulated the expression of specific genes. This marked the discovery of microRNAs (miRNAs), which are now known to be present across all forms of life. As it turns out, these molecules play essential roles in many biological processes.
A few years later, researchers realized that diseases could dysregulate the expression of miRNAs, highlighting their potential as biomarkers. In fact, abnormal miRNA expression is a hallmark of all tumor-related diseases. Thus, miRNA detection techniques ...
Research sheds light on minimally invasive neurosurgery approach
2023-04-24
Brain tumors located in regions that control speech, vision and motor function present additional challenges to neurosurgeons, as damaging the surrounding tissue can cause severe loss of those abilities.. Because of this, these regions are known as “eloquent brain areas” and require special attention and approaches to limit damage and deficits.
The University of Cincinnati’s Paolo Palmisciano, MD, was part of a research team that examined how well a minimally invasive approach worked to limit vision and hearing loss in patients following brain tumor surgery.
The research was published in the journal Brain Sciences, and the ...

A severe windstorm that battered the UK more than a century ago produced some of the strongest winds[OS1] that Britain has ever seen, a team of scientists have found after recovering old weather records.
Old weather measurements, first recorded on paper after Storm Ulysses hit the UK in February 1903, have shed new light on what was one of the most severe storms to have hit the British Isles.
By turning hand-written weather data into digital records, the research team has laid the way to better understand other historical storms, ...
New phenotyping approach analyzes crop traits at the 3D level
2023-04-24
The steady decline in cultivable land owing to the rapidly increasing global population has necessitated the use of efficient plant breeding methods that could be used to improve agricultural yields. However, in addition to genetic methods, we need approaches to control and improve complex crop traits. To this end, plant scientists make use of various cutting-edge imaging techniques that quantify crop traits (height, leaf shape, leaf color, etc.). Traditional imaging methods, however, are tedious, destructive, and non-sustainable. ...

Transforming highways for high-speed travel and energy transport
2023-04-24
WASHINGTON, April 24, 2023 – Superconductors can conduct electricity without any resistance or power loss, and they can effortlessly cause magnets to levitate above them. These properties would make superconductors useful for high-speed trains or long-distance power transmission, except for one glaring problem: superconductors only work at low temperatures, more than a hundred degrees below zero.
This one requirement makes building a hyperefficient electrical grid or high-speed rail network very expensive. Unless, that is, a superconductor network could accomplish ...

Cryo-imaging lifts the lid on fuel cell catalyst layers
2023-04-24
Proton-exchange membrane fuel cells (PEMFC), which are being developed for use in electric vehicles, rely on nanoparticles called catalysts to trigger electricity-producing reactions between hydrogen and oxygen. Most PEMFC catalysts contain platinum – a scarce and precious metal. There is therefore a pressing global need to develop catalysts that can generate the most power while minimizing platinum content.
Manufacturers integrate these catalysts in complex assemblies called catalyst layers. Until now, they had to do so without a detailed picture of the resulting structure, as traditional imaging processes almost always cause some degree of damage. Vasiliki Tileli, head ...

As “deprescribing” medicines for older adults catches on, poll shows need for patient-provider dialogue
2023-04-24
As the movement toward “deprescribing” medications among older adults grows, a new poll shows strong interest in this idea.
A full 80% of adults aged 50 to 80 would be open to stopping one or more of the prescription medicines they’ve been taking for more than a year, if a health care provider said it was possible. Already, 26% said they have done so in the past two years.
Of those willing to stop a medicine, 67% said they would likely ask for advice about doing so at their next visit with a provider, according to the new ...
