Hydrogen Peroxide is a chemical used in bleaches, dyes, cleansers, antiseptics, and disinfectants. In a concentrated form, it is toxic and irritating to tissues.
The COVID-19 pandemic has cast a harsh light on the urgent need for quick and easy techniques to sanitize and disinfect everyday high-touch objects such as doorknobs, pens, pencils, and personal protective gear worn to keep infections from spreading.
Is there a way to chemically manipulate small, confined areas on cellular surfaces? Scientists have developed a microfluidic probe to send a flow of free radicals on live cells and track the outcome using fluorescence imaging.
A new study describes the identification of new compounds from a library, with inhibitory activity against several coronaviruses. This study shows the utility of this method, besides identifying compounds that not only inhibit viral shedding in SARS-CoV-2 cultures, but have an immunomodulatory effect that may be useful in mitigating the damaging cytokine storm typical of severe or critical COVID-19.
Researchers at Rutgers School of Dental Medicine have found evidence that two types of mouthwash disrupt the COVID-19 virus under laboratory conditions, preventing it from replicating in a human cell.
Texas Biomedical Research Institute received two Department of Defense's (DoD) Defense Health Agency subcontracts to assess the efficacy of surface coating and aerosolized decontamination technologies to combat SARS-CoV-2 and other respiratory pathogens on surfaces and in the air.
Several processes in the human body are regulated by biochemical reactions involving hydrogen peroxide (H2O2).
A Mason Engineering researcher has discovered that artificial microswimmers accumulate where their speed is minimized, an idea that could have implications for improving the efficacy of targeted cancer therapy.
Those with asthma are experiencing less asthma control related to an increase in using household disinfectants -- known asthma triggers -- because of COVID-19, according to a survey co-conducted by University of Illinois Chicago researchers.
Chemical manufacturers frequently use toxic solvents such as alcohols and benzene to make products like pharmaceuticals and plastics.
A new preprint reports the efficacy of two repurposed drugs that could be useful against SARS-CoV-2 when supplemented with zinc.
With a name like glucose-6-phosphate dehydrogenase deficiency, one would think it is a rare and obscure medical condition, but that's far from the truth.
Researchers have found that oxidative stress and neurotoxicity biomarkers increased in tadpoles exposed to synthetic SARS-CoV-2 spike protein peptides.
Researchers at the University of Washington show that methylene blue (MB) and light can decontaminate masks and respirators by inactivating three tested coronaviruses without compromising integrity. The method is effective, low-cost, and does not require specialized equipment, making it applicable in any setting.
A variety of measures are necessary to prevent the spread of the coronavirus SARS-CoV-2 in hospitals and nursing homes. It is particularly important to develop an appropriate strategy to protect healthcare workers from airborne transmission.
Scientists at UC Davis Health have discovered that an enzyme in the colon lining releases hydrogen peroxide (H2O2) - a known disinfecting compound- to protect the body from gut microbes.
Cleaning surfaces with hydrogen peroxide-based disinfectants has the potential to pollute the air and pose a health risk, according to research led by University of Saskatchewan.
An international team comprising researchers from the University of Bristol, and Hunan and Central South Universities in China, have prepared biocompatible protocells that generate nitric oxide gas – a known reagent for blood vessel dilation - that when placed inside blood vessels expand the biological tissue.
At high concentrations, reactive oxygen species - known as oxidants - are harmful to cells in all organisms and have been linked to ageing.
Researchers from ITQB NOVA, in collaboration with the Institut Pasteur in Paris, have shed light on the mechanisms that allow Clostridioides difficile, a pathogen that can only grow in oxygen-free environments, to be able to survive low oxygen levels.
Human cells are encased by a membrane coated with diverse sugar molecules known as glycans. These glycans play many roles in health and disease, making them important to understand.
