Creating enough nanovesicles to inexpensively serve as a drug delivery system may be as simple as putting the cells through a sieve, according to an international team of researchers who used mouse autologous -- their own -- immune cells to create large amounts of fillable nanovesicles to deliver drugs to tumors in mice.
Nanovesicles are tiny sacs released by cells that carry chemical messages between cells. These nanovesicles are natural delivery vehicle and useful in drug delivery for cancer treatment.
DURHAM, N.C. -- Some animals are quick-change artists. Take the hogfish, a pointy-snouted reef fish that can go from pearly white to mottled brown to reddish in a matter of milliseconds as it adjusts to shifting conditions on the ocean floor.
Scientists have long suspected that animals with quick-changing colors don't just rely on their eyes to tune their appearance to their surroundings -- they also sense light with their skin. But exactly how "skin vision" works remains a mystery.
The odds of a 22-year absence of mass shootings in Australia since 1996 gun reforms being due to chance are one in 200,000, new research reveals.
Published today in the Annals of Internal Medicine, scholars at the University of Sydney and Macquarie University used mathematical techniques to test the null hypothesis that the rate of mass shootings in Australia before and after the 1996 law reforms is unchanged.
Scientists have just discovered why babies need to move in the womb to develop strong bones and joints. It turns out there are some key molecular interactions that are stimulated by movement and which guide the cells and tissues of the embryo to build a functionally robust yet malleable skeleton. If an embryo doesn't move, a vital signal may be lost or an inappropriate one delivered in error, which can lead to the development of brittle bones or abnormal joints.
ORLANDO (March 11, 2018) -- When patients who had a heart attack were given vouchers to cover their co-payments for medication to prevent a recurrence, physicians were more likely to prescribe a more effective, branded drug and patients were more likely to continue taking the medication for a full year as recommended in treatment guidelines, researchers reported at the American College of Cardiology's 67th Annual Scientific Session.
Researchers at the Intermountain Medical Center Heart Institute in Salt Lake City have found that incorporating underused, but available, imaging technologies more precisely predicts who's at risk for heart attacks and similar threats -- in time to prevent them.
For the study, researchers measured the level of calcium in the coronary arteries during stress testing using two common diagnostic tests -- positron emission tomography, or PET, and computed tomography, or CT -- to determine a patient's risk of heart disease.
A new study led by scientists from the University of Cambridge, the Institut Pasteur, Paris Diderot University, the CNRS and the genetics company 23andMe suggests that our empathy is not just a result of our education and experience but is also partly influenced by genetic variations. These results will be published in the journal Translational Psychiatry on March 12, 2018.
A recent study published in Oxford Economic Papers indicates that university education has a dramatically positive effect on the development of non-cognitive skills like conscientiousness, extraversion and agreeableness, in addition to the expected intellectual benefits. The paper also shows that the impact of education on these skills is even more dramatic for students from lower socioeconomic backgrounds.
BINGHAMTON, N.Y. - As social networking companies feel the heat to create a more socially responsible and positive experience for their millions of users, new research out of Binghamton University, State University of New York explores how the interaction of personality traits can impact the likelihood of developing an addiction to social networking.
Indonesia, a megadiverse country spanning over 17,000 islands located between Australia and mainland Asia, is home to more than 16% of the world's known amphibian and reptile species, with almost half of the amphibians found nowhere else in the world. Unsurprisingly, biodiversity scientists have been feverishly discovering and describing fascinating new animals from the exotic island in recent years.
Scientists report the existence of 15 new planets -- including one 'super-Earth' that could harbor liquid water -- orbiting small, cool stars near our solar system. These stars, known as red dwarfs[1], are of enormous interest for studies of planetary formation and evolution.
A research team led by Teruyuki Hirano of Tokyo Institute of Technology's Department of Earth and Planetary Sciences has validated 15 exoplanets[2] orbiting red dwarf systems.
As long as there have been birdwatchers, there have been lists. Birders keep detailed records of the species they’ve seen and compare these lists with each other as evidence of their accomplishments. Now those lists, submitted and aggregated to birding site eBird, can help scientists track bird populations and identify conservation issues before it’s too late.
DURHAM, N.C. -- Doctors often cite the high price of a prescription drug as a reason they don't prescribe it, while patients similarly say that cost is a main reason they quit taking a drug.
Removing this financial barrier might increase the use of evidence-based therapies, improve patient adherence to those medications, and potentially save lives. That theory was tested in a study of heart attack survivors led by the Duke Clinical Research Institute; findings were presented March 11 at the American College of Cardiology annual scientific sessions meeting in Orlando.
Patients who undergo a transcatheter aortic valve replacement, or TAVR -- a minimally-invasive surgical procedure that repairs a damaged heart valve -- experienced a significant increase in their quality of life, according to a new study by researchers at the Intermountain Medical Center Heart Institute in Salt Lake City.
Protein pathways that are closely linked to changes in both triglyceride and hemoglobin A1c levels in diabetic patients have been identified in new research by the Intermountain Medical Center Heart Institute in Salt Lake City.
The findings of two related studies bring new interest in additional research that will help healthcare providers understand the links and identify ways to intervene earlier and prevent the onset of heart disease or diabetic complications.
