Each year when influenza season arrives, experts worry that the flu vaccine won’t match the currently circulating strains of the virus. The results of an early-stage trial suggest that may become a thing of the past in the not-too-distant future. Researchers found in the Phase 1 trial that a universal flu vaccine, one designed to protect against all strains of [...]
According to a new study by Ben-Gurion University of the Negev (BGU) researchers, the natural sweetener stevia may lead to a gut microbial imbalance. The findings were just published in Molecules, a leading international peer-reviewed journal of chemistry. Stevia is a natural low-calorie sweetener that is growing in popularity in food and beverage products and is generally [...]
The omega-3 fatty acids EPA and DHA work differently against chronic inflammation, according to the results of a small randomized study, suggesting each has its own important role to play in regulating the immune system. The 34-week trial, led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (HNRCA), [...]
Abstract More representative data on source‐specific particle number emission rates and associated exposure in European households are needed. In this study, indoor and outdoor particle number size distributions (10‐800 nm) were measured in 40 German households under real‐use conditions in over 500 days. pabst_ell Read more… The post Particle number emission rates of [...]
South Korea is awaiting new social distancing measures, due to take effect Tuesday evening, as earlier measures have failed to bring new coronavirus case numbers down. The government warns of an impending crisis, brought on by a third wave of infections. New cases reported Monday exceeded 600 for the second day in a row, bringing the total to [...]
As U.S. health authorities continue examining the proposed COVID-19 vaccines, residents in the United Kingdom — the first Western country to issue approval for emergency use — are set to receive their first shots as early as this week. But quickly vaccinating as many people as possible in the U.K. will pose enormous logistical challenges — [...]
Alcohol, 60% concentration. That’s what your hand sanitizer needs to reliably kill the SARS-CoV-2 virus, according to the CDC. But new research out of BYU, published in the Journal of Hospital Infection, challenges this notion. It found that three commercial disinfectants—used in many hand sanitizers and surface wipes as alternatives to alcohol—kill the virus effectively. Most crucially, [...]
As restrictions are slowly lifted and more and more people head to indoor spaces like restaurants, bars or classrooms, scientists around the world have a warning: there’s another way to get COVID-19 that health authorities have been ignoring. The post Portland researcher warns about airborne transmission of COVID-19 appeared first on Healthier Environment Living Program.
This video is a short description of using air cleaners to supplement ventilation for reducing the risk of getting infected by long-range exposure to airborne virus particles. It shows briefly how to use the Harvard CU_Boulder air cleaner sizing tool. The post Harvard CU-Boulder air cleaner sizing tool, Presentation by Dr. Shelly L. Miller appeared [...]
Abstract Wheezing and asthma are a growing cause of morbidity in children and adults. Treatment is aimed at prevention of disease exacerbations and preservation of lung function. Respiratory viruses are involved in ∼40–60% of exacerbations. Bacterial lysates prevent recurrent respiratory tract infections and might reduce exacerbations. Moreover, immunomodulatory effects have been observed in human and animal [...]
