Timely treatment is critical for stroke victims, yet only 19.8% of the U.S. population can access a stroke center capable of endovascular thrombectomy to remove a large clot in 15 minutes or less by ambulance, according to researchers from The University of Texas Health Science Center at Houston (UTHealth). Only 30% of Americans can access a thrombectomy-equipped center in 30 minutes.
The study, published in Stroke, assessed the current state of access to endovascular thrombectomy treatment in the U.S. and evaluated two different strategies to optimize it.
RESEARCH TRIANGLE PARK, N.C. -- A new computational model could be used to expedite military operations aimed at evacuating civilians during disaster response or humanitarian relief.
Researchers at North Carolina State University, with funding from the U.S. Army, designed a new model to help planners and logisticians determine what needs to be where and at what time in order to complete an evacuation as quickly as possible. This includes where vehicles need to be when, and routing alternatives as well as supply requirements by location over time for food, water and shelter.
UNIVERSITY PARK, Pa. -- Researchers at Penn State are taking steps to address the alarming rate of suicides among indebted farmers in India, by developing a deep-learning algorithm as the first step in a decision-support system that could predict future market values of crops.
Stem cells involved in replenishing human tissues and blood depend on an enzyme known as telomerase to continue working throughout our lives. When telomerase malfunctions, it can lead to both cancer and premature aging conditions. Roughly 90% of cancer cells require inappropriate telomerase activity to survive.
Many people with chronic health conditions search social media, including YouTube videos, to learn more about how to manage their diagnoses. But these videos differ in how well they communicate information and hold viewers' attention. A better understanding of how patients engage with medical information is important for improving the use of health care resources and the quality of care. A new study sought to understand how people engage with health information in YouTube videos on diabetes.
Recurrent, unplanned readmissions to the hospital -- which happen when patients return shortly after discharge and are readmitted for the same or a related condition -- are a challenge worldwide. Many researchers have examined how to predict them and how to understand the factors that contribute to them. A new study looked at how the risk of readmission progressed over multiple visits to emergency departments (EDs) in Israel by patients with chronic diseases.
Think dietary fiber is just for digestive health? Think again.
Specific fibers known as prebiotics can improve sleep and boost stress resilience by influencing gut bacteria and the potent biologically active molecules, or metabolites, they produce, new University of Colorado Boulder research shows.
The research could ultimately lead to new approaches to treating sleep problems, which affect 70 million Americans.
In animals, releasing eggs in a timely manner is vital to maximize the chances of successful fertilization.
However, how this process evolved and is controlled in different species is poorly understood. A new regulator of egg release has been identified in jellyfish in a new study published March 3 in the open-access journal PLOS Biology by Gonzalo Quiroga Artigas and Evelyn Houliston of Sorbonne University, France, and colleagues. The finding sheds light on how the complex hormonal control of sexual reproduction in animals evolved.
BIRMINGHAM, Ala. - A new culprit -- hydrogen sulfide -- has been found for the deadly infectious disease tuberculosis. Hydrogen sulfide gas is known for its rotten egg smell, yet it has normal physiological roles in the human body to communicate among cells.
Leesburg, VA, March 3, 2020--A multi-center study (n=101) of the relationship between chest CT findings and the clinical conditions of coronavirus disease (COVID-19) pneumonia--published ahead-of-print and open-access in the American Journal of Roentgenology (AJR)--determined that most patients with COVID-19 pneumonia have ground-glass opacities (GGO) (86.1%) or mixed GGO and consolidation (64.4%) and vascular enlargement in the lesion (71.3%).
A team of researchers led by the Biology Department at the University of Hawai'i at Hilo has its new study on animal biodiversity patterns on the planet featured in the February 28, 2020 issue of the journal Science.
American culture values the freedom to change and reinvent one's self. A new study, however, reveals that Americans who do change tend to report a lower sense of well-being.
University of Georgia psychologists compared individual self-concepts between Americans and Japanese counterparts and uncovered this essential contradiction about the heroic myth of American individualism.
The findings were published in the journal Social Psychological and Personality Science.
ITHACA, N.Y. - Gene drives use genetic engineering to create a desired mutation in a few individuals that then spreads via mating throughout a population in fewer than 10 generations.
In theory, such a mechanism could be used to prevent malarial mosquitoes from transmitting disease, or possibly to wipe out an invasive species by disabling its ability to reproduce.
ROCHESTER, Minn. -- The toxic protein tau is a key biological feature in the brains of people with Alzheimer's disease. Yet the factors that make people susceptible or resistant to tau accumulation are not well-understood. A preliminary Mayo Clinic study shows that inherited DNA variants may be associated with developing tau deposits in older adults. The research will be presented at the American Academy of Neurology's 72nd Annual Meeting in Toronto April 25-May 1.
Through a technique known as DNA origami, scientists have created the fastest, most persistent DNA nano motor yet. Angewandte Chemie published the findings, which provide a blueprint for how to optimize the design of motors at the nanoscale -- hundreds of times smaller than the typical human cell.
