ORLANDO, Fla. (October 15, 2020) - A group of three gene variants, commonly inherited together, may provide clues to more successful treatment of pediatric eosinophilic esophagitis (EoE), a chronic inflammation of the food pipe often confused with gastroesophageal reflux disease (GERD). A new study, led by researchers from Nemours Children's Health System and published in Clinical Gastroenterology and Hepatology, identifies genetic variants that help predict which children with EoE may not respond to proton pump inhibitor (PPI) medication therapy as a long-term solution.
Anyone who has experienced "butterflies in the stomach" before giving a big presentation will be unsurprised to learn there is a physical connection between their gut and their brain. Neuroscientists and medical professionals call this connection the "gut-brain axis" (GBA); a better understanding of the GBA could lead to the development of treatments and cures for neurological disorders such as depression and anxiety, as well as for a range of chronic auto-immune inflammatory diseases such as irritable bowel syndrome (IBS) and rheumatoid arthritis.
People who live through traumatic experiences in childhood often suffer long-lasting consequences that affect their mental and physical health. But moreover, their children and grand-children can also be impacted as well. In this particular form of inheritance, sperm and egg cells pass on information to offspring not through their DNA sequence like classical genetic heredity, but rather via biological factors involving the epigenome that regulates genome activity. However, the big question is how the signals triggered by traumatic events become embedded in germ cells.
Autonomous vehicles (AV) are the wave of the future in the automobile industry, and there's extensive discussion about the impacts on transportation, society, the economy and the environment.
However, less attention has been focused on the potential health impacts of self-driving vehicles.
Researchers at the University of Colorado Boulder and the University of Colorado Anschutz Medical Campus have developed a new way to diagnose diseases of the blood like sickle cell disease with sensitivity and precision and in only one minute. Their technology is smaller than a quarter and requires only a small droplet of blood to assess protein interactions, dysfunction or mutations.
The team published its results Oct. 15 in the journal Small.
A unique study conducted by University of Georgia entomologists led to the discovery of a distinctive supergene in fire ant colonies that determines whether young queen ants will leave their birth colony to start their own new colony or if they will join one with multiple queens.
Researchers also found that ants were more aggressive toward queens who don't possess the supergene, causing main colony workers to kill them. This critical finding opens the door to new pest control methods that may be more efficient in eradicating problematic fire ant colonies.
TALLAHASSEE, Fla. -- Researchers are learning more about the brightly colored bacterial mats threatening the ecological health of coral reefs worldwide. In new research released this month, a Florida State University team revealed that these mats are more complex than scientists previously knew, opening the door for many questions about how to best protect reef ecosystems in the future.
Dietary supplementation of fatty acids produced from microalgae have wide-reaching health benefits for humans, including the ability to reduce obesity, diabetes and fatty liver disease, preventing hair loss, and assisting wounds to heal.
However, its widespread development has been hampered by the current limits of bioimaging tools needed to allow easy, rapid and non-invasive evaluation of lipid conditions within microalgae.
When COVID-19 hit the United States, small towns near ski areas such as Park City, Utah, and Sun Valley, Idaho, experienced some of the highest per capita cases; people from around the world had brought the virus along with their skis. As the coronavirus spread, gateway communities--communities near scenic public lands, national parks, and other outdoor recreational amenities--felt acute economic pressure as the virus forced them to shut down tourist activities.
40% of tenant households across Australia indicated that after paying rent there was not enough money left over to buy essentials due to COVID lockdowns
One third of renters surveyed were ignored or unable to negotiate a rent reduction with their landlord
5% of renters were issued with an eviction notice during the pandemic
Around half of survey respondents indicated that their mental health had been negatively affected by COVID-19 lockdowns.
There is an old saying, "If rubber is the material that opened the way to the ground, aluminum is the one that opened the way to the sky." New materials were always discovered at each turning point that changed human history. Materials used in memory devices are also drastically evolving with the emergence of new materials such as doped silicon materials, resistance changing materials, and materials that spontaneously magnetize and polarize. How are these new materials made?
CHICAGO, Oct. 15, 2020 -- Although assumed to be at high risk for COVID-19, fewer than one percent of dentists nationwide were found to be COVID-19 positive, according to a first-of-its-kind report in the U.S. based on data collected in June 2020. The result is far below that of other health professionals in the U.S. In addition, 99 percent of dentists are using enhanced infection control procedures such as screening protocols and enhanced disinfection practices when treating patients.
Of the six or more different species of early humans, all belonging to the genus Homo, only we Homo sapiens have managed to survive. Now, a study reported in the journal One Earth on October 15 combining climate modeling and the fossil record in search of clues to what led to all those earlier extinctions of our ancient ancestors suggests that climate change--the inability to adapt to either warming or cooling temperatures--likely played a major role in sealing their fate.
Along with the woolly mammoth and the giant ground sloth, the sabre-toothed cats were probably among the most famous animals that lived during the Pleistocene Epoch and went extinct before the end of last ice age. Over the years, sabre-toothed cats have also been the subject of many research projects.
