A new study in Burns & Trauma, published by Oxford University Press, reveals promising new strategies to prevent skin scarring after injuries.
While scars are common when wounds heal, hypertrophic scarring is a skin condition characterized by deposits of excessive amounts of collagen. This results in a thick and often raised scar. The underlying mechanisms of hypertrophic scar development are poorly understood, however. The Burns & Trauma paper reviewed strategies for treating hypertrophic scars.
ITHACA, N.Y. - One strategy for reducing food waste's environmental impact is as counterintuitive as it is straightforward: Open more grocery stores.
That's according to new research from Elena Belavina, associate professor at the School of Hotel Administration in the Cornell University SC Johnson College of Business.
Why are some people better able to fight off the flu than others? Part of the answer, according to a new study, is related to the first flu strain we encounter in childhood.
MEDFORD/SOMERVILLE, Mass. (February 4, 2020)-- Researchers led by biologists at Tufts University have discovered that the brains of developing embryos provide signals to a nascent immune system that help it ward off infections and significantly improve the embryo's ability to survive a bacterial challenge. Using frog embryos, which continue to develop with their brains removed, the researchers found that embryos without a brain are not able to marshall the forces of immune cells to an injury or infection site, leading the embryo to succumb to an infection more quickly.
It may not always seem so, but scientists are convinced that humans are unusually cooperative. Unlike other animals, we cooperate not just with kith and kin, but also with genetically unrelated strangers. Consider how often we rely on the good behavior of acquaintances and strangers-- from the life-saving services of firefighters and nurses, to mundane activities like our morning commute and queueing at the airport check-in counter. Of course, we encounter people who cheat, disregard the welfare of others, and engage in cronyism and nepotism.
BINGHAMTON, N.Y. ? Publicly sharing a goal may help you persist after hitting a failure, but only if you care about what others think of you, according to new research from Binghamton University, State University of New York.
However, public announcements, such as Facebook posts about New Year's resolutions or weight loss targets, may only be motivating when there is immediate feedback after a failure and if there is a high incentive in reaching a goal.
To address the receptor dysfunction associated with several serious neurological diseases, Michaela Jansen, Pharm.D., Ph.D., from the Texas Tech University Health Sciences Center School of Medicine recently completed a study that provides novel insights into a protein-protein interaction that may one day lead to more effective treatments for these disorders. The study, "Delineating the site of interaction of the 5-HT3A receptor with the chaperone protein RIC-3," was recently published in Biophysical Journal.
February 4, 2020 -- A new study shows that having general anesthesia in a cesarean delivery is linked with significantly increased odds of severe postpartum depression requiring hospitalization, thoughts of suicide or self-inflicted injury.
As the use of marijuana is legalized in an increasing number of U.S. states, the number of people who use the drug daily is on the rise. This upward trend also holds up in women who are pregnant or breastfeeding, despite evidence that using marijuana could harm their babies.
Depression, anxiety, impulsive behaviour and poor cognitive performance in children is effected by the amount of sleep they have researchers from the University of Warwick have found.
Sleep states are active processes that support reorganisation of brain circuitry. This makes sleep especially important for children, whose brains are developing and reorganizing rapidly.
Currently, 90% of the hydrocarbon resources of the entire continental shelf of Russia are concentrated in the Arctic, including 70% on the shelf of the Barents and Kara Seas. Scientists understand that the shelf is a promising future, and the necessary technological basis for its future development should already be created.
Researchers from the group of Jeroen Bakkers at the Hubrecht Institute (KNAW) have found that the muscle cells in the heart of zebrafish change their metabolism, the way in which they generate energy, during heart regeneration. Contrary to the human heart, the zebrafish heart can regenerate after injury.
Ribonucleic acids (RNA) ensure that the blueprint in the cell nucleus is translated into vital proteins and that cell functions are regulated. However, little is known about the structure and function of particularly long RNAs, which consist of hundreds or thousands of building blocks. Chemists at the University of Bonn have now developed a new method for this purpose: They mark the complex molecules with tiny "flags" and measure the distances between them with a "molecular ruler".
Matching behavior with the way you feel - in other words, not faking it - is more productive at work and leads to other benefits, according to a new study co-authored by Chris Rosen, management professor in the Sam M. Walton College of Business at the University of Arkansas.
Rosen helped design and write a study led by Allison Gabriel, associate professor of management and organizations at the University of Arizona. They published their findings in the Journal of Applied Psychology.
URBANA, Ill. - Urban areas face increasing problems with stormwater management. Impervious surfaces on roads and buildings cause flooding, which impacts the water quality of streams, rivers and lakes. Green infrastructure, including features such as rain barrels, green roofs, rain gardens, and on-site water treatment, can provide affordable and environmentally sound ways to manage precipitation.
