What The Study Did: A variety of data were used to estimate annual health care spending in the U.S. from 1996 through 2016 by payer (public insurance, private insurance and out-of-pocket payments) and by health conditions, including low back pain and musculoskeletal disorders, diabetes and ischemic heart disease. This study is part of a theme issue from JAMA on drug pricing.
Authors: Joseph L. Dieleman, Ph.D., of the Institute for Health Metrics and Evaluation in Seattle, is the corresponding author.
You just finished a good meal and are feeling full? Researchers from the CNRS, Inrae, University of Burgundy, Université de Paris, Inserm, and University of Luxembourg (1) have just revealed the mechanisms in our brains that lead to this state. They involve a series of reactions triggered by a rise in blood glucose levels. This study, which was conducted on mice, is published in Cell Reports on 3 March 2020.
The historic economies of Mongolia are among the least understood of any region in the world. The region's persistent, extreme winds whisk away signs of human activity and prevent the buildup of sediment which archaeologists rely on to preserve the past. Today crop cultivation comprises only a small percent of Mongolia's food production, and many scholars have argued that Mongolia presents a unique example of dense human populations and hierarchical political systems forming without intensive farming or stockpiling grains.
Oxytocin is known for its role in childbirth and breastfeeding and it has also been shown to have a wider application in the development and regulation of social behaviour in many species. There has been increasing interest in its potential use to help people overcome social difficulties as this can be one of the most difficult symptoms to treat in many psychiatric conditions such as schizophrenia, autism, anxiety and depression.
WASHINGTON, March 3, 2020 -- Recent advances in bioengineering and computational modeling have given researchers the ability to examine complex biological processes with molecular-level detail.
Researchers in Simon Fraser University's Brinkman Laboratory are collaborating with U.S. researchers to test a new drug that can kill a wide range of superbugs - including some bacteria now resistant to all common antibiotics.
Known as AB569, the drug contains ethylenediaminetetraacetic acid (commonly referred to as EDTA) and acidified nitrite, two inexpensive chemicals that the researchers discovered work together to effectively kill disease-causing bacteria without harming human cells.
Delivery services have increased rapidly with the expansion of online shopping and, in Japan, failed deliveries that result in redelivery attempts occur 20% of the time. In terms of labor, fuel, and environmental (increased CO2 emissions) costs, empty homes causing redeliveries have become an issue. Until now, long-term trends of households with every member out-of-home has not been fully clarified.
Mangroves account for only 0.7 per cent of the Earth's tropical forest area, but they are among the world's most productive and important ecosystems. They provide a wealth of ecological and socio-economic benefits, such as serving as nursery habitat for fish species, offering protection against coastal surges associated with storms and tsunamis, and storing carbon.
Researchers from Tokyo Medical and Dental University (TMDU) discover a novel mechanism by which immunodeficiency viruses evolved over time to evade the protective measures of the host
Red panda population genomics confirms two phylogenetic species and different evolutionary histories
The red panda (Ailurus fulgens) is an endangered mammal endemic to the Himalaya and Hengduan Mountains, and its distribution spans China, Myanmar, Bhutan, India and Nepal. Prior to 1902, all red pandas were classified as one species. However, in 1902, scientists established two subspecies, based on their morphological differences: the Himalayan subspecies (A. f. fulgens) and the Chinese subspecies (A. f. styani).
Researchers identified an increased prevalence of five traits associated with previous extinction-survival responses among corals.
Human-driven climate change is rapidly increasing stressors on coral communities, such that 75% of species could become extinct within the next few centuries.
NEW YORK, March 3, 2020 -- A study published Tuesday in Scientific Reports shows that stony corals, which provide food and shelter for almost a quarter of all ocean species, are preparing for a major extinction event.
Actin filaments have several important functions inside cells. For one, they support the cell membrane by binding to it. However, scientists did not know exactly how the actin interacts with the membrane lipids. Simulations performed at the University of Groningen, supported by experiments, provide a molecular view on this very fundamental process. The results were published in the journal Proceedings of the National Academy of Sciences on 2 March.
University of Kent research suggests that men can distinguish between the scents of sexually aroused and non-aroused women.
The detection of sexual arousal through smell may function as an additional channel in the communication of sexual interest and provide further verification of human sexual interest.
Scientists at the Laboratoire des Maladies Neurodégénératives (CNRS/CEA/Université Paris-Saclay) and the Neurocentre Magendie (INSERM/Université de Bordeaux) have just shown that a metabolic pathway plays a determining role in Alzheimer's disease's memory problems. This work, published on 3 March 2020 in Cell Metabolism, also shows that supplying a specific amino acid as a nutritional supplement in a mouse model of Alzheimer's restores spatial memory affected early. This is a promising path for reducing memory loss related to that disease.
Studying the inner ear of apes and humans could uncover new information on our species' evolutionary relationships, suggests a new study published today in eLife.
