PROVIDENCE, R.I. [Brown University] -- As researchers and medical professionals work to develop new treatments for cancer, they face a variety of challenges. One is intratumor heterogeneity -- the presence of multiple kinds of cancer cells within the same tumor. Often, these "mosaic" tumors include cells, such as polyploidal giant cancer cells, that have evolved to become aggressive and resistant to chemotherapy and radiation.
Results from a new study published in Alzheimer's & Dementia support emerging evidence suggesting that noise may influence individuals' risk of developing dementia later in life.
Numerous studies have examined interventions aimed at preventing violence against children. A recent analysis reveals various gaps not adequately addressed by these studies.
The cover for issue 31 of Oncotarget features Figure 4, "Concentration dose-response curves of sirolimus effect [55 nM–1 nM] on the number of cells per surviving colony in U2OS cell line after 2 weeks exposure," by Vasuri, et al.
(Boston)-- Although frequently used to treat painful osteoarthritis of the hip and knee, intra-articular corticosteroid (IACS) injections remain controversial. Questions about whether damage to joints occurs as a result of these injections, which are performed thousands a time each day, persist.
WASHINGTON, October 20, 2020 -- As the coronavirus has affected more than 30 million people globally, researchers have increasingly focused on the extent to which airborne respiratory droplets carrying the virus travel and contaminate the air after an infected person coughs.
More than 480,000 U.S. deaths per year, as well as diseases affecting 16 million living Americans, can be attributed to cigarette smoking, according to the Centers for Disease Control and Prevention. In particular, this behavior continues to be overrepresented among those with mental illness, substance use disorders, and socioeconomic disadvantage.
With cases increasing in the UK and elsewhere, and winter approaching, there is an urgent need for reliable models that predict the likely course of Covid-19, to support decisions about shielding, hospital admission, treatment, and vaccinations.
WASHINGTON, October 20, 2020 -- Contagion processes, such as opinion formation or disease spread, can reach a tipping point, where the contagion either rapidly spreads or dies out. When modeling these processes, it is difficult to capture this complex transition, making the conditions that affect the tipping point a challenge to uncover.
HAMILTON, ON, Oct. 20, 2020 -- When COVID-19 attacks, the immune system produces a cytokine, or protein, called Interleukin-6 (IL-6), whose concentrations can offer vital information about a patient's level and stage of infection.
But measuring the critical marker has been extremely challenging, given its nearly undetectable presence in the biological stew that makes up human blood. Existing technology has not been accurate or sensitive enough to measure concentrations of IL-6 well enough to be reliable, especially in low concentrations.
Cannabinoids have a strong influence on how our brains work and how we behave. Many people are only aware of the recreational aspect of cannabinoids. But in fact these molecules naturally exist in our brains where they participate in various intrinsic processes.
Altered cannabinoid signalling, for instance due to chronic use of marijuana, results in a range of impairments. Similarly, mice lacking cannabinoid receptors exhibit reduced activity levels, as well as deficits in learning and memory.
COLUMBUS, Ohio - A blend of racial prejudice, poor coping and partisan media viewing were found in Americans who stigmatized people of Asian descent during the COVID-19 pandemic, according to a new study.
But it was prejudice against Asian Americans that was most strongly linked to beliefs that Asians were responsible for the pandemic and most at risk for spreading it, results showed.
Programmes to reduce dementia risk by targeting smoking, high blood pressure and hearing loss are likely to be cost-effective and cost saving by reducing dementia rates by 8.5%, finds a new study by UCL and LSE researchers.
The modelling study, published in The Lancet Healthy Longevity, found that the benefits would outweigh the costs of such programmes, and could save £1.86 billion each year in England.
Games and the very act of playing have been around since before the cradle of human civilization. However, games have constantly evolved over time, with various rulesets and modes of play falling in and out of favor throughout history. In turn, this implies that people at different times enjoyed different aspects of each game, which may constitute a vivid reflection of the cultural tendencies of each era. Unfortunately, the attractiveness of games is tied to human psychology, and finding objective evidence in topics related to the realm of the human mind is a difficult task.
Which political parties have the most ambitious climate and energy policies? The answer, according to a new study, is surprising. In Germany, France, Spain and Italy, parties across the political spectrum, from the Greens to the Liberals, show a similar level of ambition on this score. However, researchers have also identified a major impediment to the energy transition: none of the investigated parties has a convincing idea for a technology mix that would ensure grid stability despite weather-related fluctuations in wind and solar energy.
