New data from a landmark study done by Monash University researchers in Australia raises significant concerns that even short-term exposure to low level air pollution can affect gene expression, leaving us at risk of other diseases such as cancer, cardiovascular and respiratory diseases. Research, published in the journal Environment International, provides the first evidence that exposure to even very low levels of air pollution can change gene expression that are the hallmark of diseases such as cancer.
Chemotherapeutic drugs, also known as antineoplastic agents, that are prescribed to treat a range of cancer types, enter the aquatic environment via human excretion and wastewater treatment facilities. A review published in Environmental Toxicology and Chemistry indicates that very few studies have characterized the effects of antineoplastic agents that are released into aquatic environments.
People who live in urban areas with higher levels of air pollution may score lower on thinking and memory tests and may also lose cognitive skills faster over time, or it is possible they also may not, according to a study published in the April 8, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
In Uganda, loss of forested habitat increases the likelihood of interactions between disease-carrying wild primates and humans. The findings suggest the emergence and spread of viruses, such as the one that causes COVID-19, will become more common as the conversion of natural habitats into farmland continues worldwide.
A team of researchers in Wuhan, China have developed a multidisciplinary self-managed home quarantine method that was effective in controlling the source of COVID-19 infection and was useful in alleviating the shortage of medical resources.
As COVID-19 spreads across the globe, a common question is, can infectious diseases be connected to environmental change? Yes, indicates a study published today from the University of California, Davis' One Health Institute. Exploitation of wildlife by humans through hunting, trade, habitat degradation and urbanization facilitates close contact between wildlife and humans, which increases the risk of virus spillover, the study found. Many of these same activities also drive wildlife population declines and the risk of extinction.
A group of scientists from Aarhus University in Denmark and University of Siena in Italy has found another small piece in the puzzle of understanding COVID-19. Looking for reasons why the mortality rate is up to 12% in the northern part of Italy and only approx. 4.5% in the rest of the country, they found a probable correlation between air pollution and mortality in two of the worst affected regions in northern Italy.
Using a bedroom air filter that traps particles of pollution with diameters smaller than 2.5 micrometers can significantly improve breathing in asthmatic children, a new Duke University-led study by American and Chinese scientists shows. It's the first study to document that physiological improvements occur in the children's airways when the air filters are in use, and it suggests that with consistent use the filters may help prevent, not just alleviate, asthmatic flare-ups.
Surgical masks may help prevent infected people from making others sick with seasonal viruses, including coronaviruses, according to new research. In laboratory experiments, the masks significantly reduced the amounts of various airborne viruses coming from infected patients, measured using the breath-capturing 'Gesundheit II machine' developed by Dr. Don Milton, professor in the University of Maryland School of Public Health and a senior author of the study published April 3 in the journal Nature Medicine.
Researchers at UC Riverside and the University of Salerno have called for more research to determine the best ways to keep SARS-CoV-2 out of the water cycle. They also suggest that developed nations should finance water treatment systems in the developing world to help prevent future COVID-19 pandemics.
