Researchers at Portland State University have developed methods for measuring levels of free-base nicotine in electronic cigarette (e-cigarette) liquids and vapor, the levels of which are associated with harshness upon inhalation of e-cigarette vapors and tobacco smoke.
Videos and creative uses of other visuals provide a novel way to obtain informed consent during clinical trials to improve participants' understanding and retention of trial information, according to a study by Nemours Children's Health System presented at the American Thoracic Society (ATS) Annual Conference.
Researchers at The University of Texas at Arlington have found a correlation between a strong immune response in diseased corals and a lower expression of genes associated with growth and reproduction.
Kessler Foundation researchers compared two neuropsychological tests for assessing learning in individuals with multiple sclerosis. 'Comparing the Open Trial - Selective Reminding Test results with the California Learning Verbal Test II in Multiple Sclerosis' was published online on April 4, 2018, in Applied Neuropsychology: Adult. This is the first study to compare the two tests in the same individuals with MS.
Origami -- the Japanese art of folding paper into shapes and figures -- dates back to the sixth century. At UMass Lowell, it is inspiring researchers as they develop a 21st century solution to the shortage of tissue and organ donors.
Researchers from University of California San Diego School of Medicine and Arizona State University found that if a car is parked in the sun on a summer day, the interior temperature can reach 116 degrees F. and the dashboard may exceed 165 degrees F. in approximately one hour -- the time it can take for a young child trapped in a car to suffer fatal injuries.
Chemist Vincent Rotello at UMass Amherst, with others at University College London, have developed a 'quick and robust' blood test that can detect liver damage before symptoms appear, offering what they hope is a significant advance in early detection of liver disease. Details appear in Advanced Materials. Their new method can detect liver fibrosis, the first stage of liver scarring that can lead to fatal disease if left unchecked, from a blood sample in 30-45 minutes.
Researchers at Western University were interested in the origin of a gene that encodes for protein, HERC5, shown to potently inhibit HIV. In a new study published in the Journal of Virology, Stephen Barr, Ph.D., assistant professor at Western's Schulich School of Medicine & Dentistry, shows that the gene first emerged in fish over 400 million years ago and has been involved in an evolutionary arms race with viruses ever since.
An article published in Annals of Allergy, Asthma and Immunology shows allergies can have serious, far-reaching consequences, especially on adolescent sufferers.
In the journal Nature Communications, researchers from the UNC Lineberger Comprehensive Cancer Center report that for a particular subset of lung cancer tumors, there is a high prevalence of immune cells called inflammatory monocytes. These immune cells, which normally help to build clotting scaffolds to promote wound healing, also make it possible for tumor cells to migrate and spread to other parts of the body.
