Edentulous jaw is a condition where either the upper (maxilla) or the lower (mandible) jaw is missing all teeth. In medical practice, it could be treated by placement of a complete denture.
If Americans adhere to global dietary recommendations designed to reduce the impact of food production and consumption, environmental degradation could be reduced by up to 38%, according to a new paper published in the journal Environmental Justice.
Researchers led by prof. Wout Boerjan (VIB-UGent Center for Plant Systems Biology) have discovered a way to stably finetune the amount of lignin in poplar by applying CRISPR/Cas9 technology. Lignin is one of the main structural substances in plants and it makes processing wood into, for example, paper difficult. This study is an important breakthrough in the development of wood resources for the production of paper with a lower carbon footprint, biofuels, and other bio-based materials.
Colorectal cancer (CRC) is the third most common cancer in the world, with more than one and a half million new cases diagnosed annually. Approximately 20% of diagnosed stage II patients experience relapses after surgery. There is no marker yet that identifies stage II patients at risk of relapse. Therefore, it is important to be able to identify prognostic biomarkers for this specific setting.
Pigment Blue 15:3 and Pigment Green 7 are also affected by this proposal. Because of these pigments in particular, the ECHA proposal is currently the subject of public debate.
As a consequence, the German Federal Institute for Risk Assessment (BfR) has reviewed the potential health hazards and risks posed by the pigments Blue 15:3 and Green 7.
A growing area of medicine looks at how cellular binding observed in nature - where molecules like viruses or proteins bind to specific receptors on a cell - can be mimicked to aid drug delivery.
Those developing targeted drug therapies aim to recreate this precise binding to develop nano-sized drug carriers that attach only to diseased cells. Once attached, these carriers would release their therapeutic load without affecting healthy cells. If drugs can be specifically targeted in this way, treatments would cause far fewer side effects.
A polymer previously used to protect solar cells may find new applications in consumer electronics, reveals a KAUST team studying thin films capable of converting thermal energy into electricity.
Chemotherapy-based cancer treatment has distressing side effects for patients and increases the risk of developing resistance to the treatment. In an attempt to solve these problems, scientists from the University of Geneva (UNIGE) have developed a technique for quickly identifying from a large number of existing drugs the optimal synergistic combination and dose of products that can kill the tumour cells without affecting healthy cells.
Surviving on a warming planet can be a matter of timing--but simply shifting lifecycle stages to match the tempo of climate change has hidden dangers for some animals, according to new research from the Max Planck Institute of Animal Behaviour and Cornell University.
The study, published in PNAS, has uncovered drastic consequences for birds that are breeding earlier in lockstep with earlier starts of spring: chicks hatching earlier face increased risk of poor weather conditions, food shortages and mortality.
When it comes to making decisions about investments, medical treatment, or insurance policies, we are more worried about financial loss than we are confident about monetary gain. But the intricacies of how our brain functions to bring about these sentiments are not clear.
PROVIDENCE, R.I. [Brown University] -- Government officials vastly undercounted the death toll among Florida nursing home residents after the destruction of Hurricane Irma in 2017, according to new research led by a Brown University scholar who studies disaster management in the long-term care industry.
WASHINGTON--Warmer winters due to climate change are causing lakes in the Northern Hemisphere to experience more ice-free years, according to a new study.
PROVIDENCE, R.I. [Brown University] -- Nursing home residents tend to fall asleep at all hours of the day, and during the night, their sleep may be interrupted by periods of wakefulness.
It's a vicious cycle of fragmented sleep that can place residents at risk for poor health outcomes, including depression and increased frailty, said Rosa Baier, an associate professor of the practice in health services, policy and practice who directs the Center for Long-Term Care Quality & Innovation at the Brown University School of Public Health.
EUGENE, Ore. - Oct. 6, 2020 - Researchers probing peatlands to discover clues about past environments and carbon stocks on land have identified peatland that is twice as old and much deeper than previously thought.
Their findings, detailed in an open-access paper published Sept. 14 in the journal Environmental Research Letters, show that an inland site near Putussibau, not far from the Indonesia-Malaysia border, formed at least 47,800 years old and contains peat 18 meters deep - roughly the height of a six-story building.
The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers at the University of California, Davis, found that the combined threats reduced blue orchard bee reproduction by 57 percent and resulted in fewer female offspring. The study was published in the journal Proceedings of the Royal Society B.
