A recently completed study indicates that smoking by pregnant mothers caused roughly an 1.5-fold asthma risk in their offspring at the ages between 31 and 46.
With the coronavirus pandemic temporarily shuttering hair salons, many clients are appreciating, and missing, the ability of hair dye to cover up grays or touch up roots. However, frequent coloring, whether done at a salon or at home, can damage hair and might pose health risks from potentially cancer-causing dye components. Now, researchers reporting in ACS Central Science have developed a process to dye hair with synthetic melanin under milder conditions than traditional hair dyes.
Researchers report the development of a sensitive and specific assay to detect different serotypes of Salmonella, paving the way for rapid serotyping directly from specimens. This improvement upon current testing methods can play a critical role in quickly tracing the origin of the infection. The report appears in The Journal of Molecular Diagnostics, published by Elsevier.
Researchers report evidence that the compounds in e-cigarette liquid could potentially cause the body's tissue repair process to go haywire and lead to scarring inside the lungs. The new study, conducted in cell cultures, also suggests that inhibiting a certain nicotinic receptor could help promote the death of overactive fibroblast cells and thus slow scar formation, called fibrosis, in affected individuals.
Scientists have identified a collection of biomarkers that together signal that a person's cancer treatment may be harming their heart.
The researchers discovered that encapsulating ellagic acid in chitosan, a sugar, reduces its inherent cytotoxicity while enhancing its antioxidant properties. The chitosan shell, which makes up the hard outer skeleton of shellfish, also permits EA delivery via a rapid burst phase and a relatively slow phase. This further enhances the drug delivery because the nanohybrid vehicle is uniquely suited for drug release over extended time periods.
A new approach to monitoring the novel coronavirus, (as well as other dangerous pathogens and chemical agents), is being developed and refined. Known as wastewater-based epidemiology (WBE), the method mines sewage samples for vital clues about human health. It can potentially identify levels of coronavirus infection at both a local and global scale.
What makes SARS-CoV-2, the virus behind COVID-19, such a threat? A new study in the journal Cell, led by Jose Ordovas-Montanes, PhD at Boston Children's Hospital and Alex K. Shalek, PhD at MIT pinpoints the likely cell types the virus infects. Unexpectedly, it also shows that one of the body's main defenses against viral infections may actually help the virus infect those very cells.
In a review paper published in the journal Nature Reviews Earth & Environment, WHOI scientists review what they-- and their science colleagues from around the world--have learned from studying the spill over the past decade.
In a pair of new studies, Rolf Halden, director of the ASU Biodesign Center for Environmental Health Engineering and author for the 2020 Book Environment, describes the process and highlights important new findings extracted from the municipal wastewater most of us contribute to on a daily basis. Halden is also a professor at ASU's School of Sustainable Engineering and the Built Environment.
