Hydrogen Peroxide is a chemical used in bleaches, dyes, cleansers, antiseptics, and disinfectants. In a concentrated form, it is toxic and irritating to tissues.
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.
Researchers at The Wistar Institute and collaborators from the University of Notre Dame are developing anticancer compounds targeting a pathway of the endoplasmic reticulum (ER) stress response implicated in the development of multiple myeloma (MM), chronic lymphocytic leukemia (CLL) and lymphoma.
In their quest to destroy cancer cells, researchers are turning to combinational therapies more and more. Scientists from Germany and China have now combined a chemotherapeutic and photodynamic approach.
A new pilot study by US researchers demonstrates an alternative approach to long-lasting disinfection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by using cationic phenylene ethynylene polymers and oligomers (i.e., conjugated electrolytes). The paper is currently available on medRxiv* preprint server.
Researchers from UCLA and China have found that catalase, a naturally occurring enzyme, holds potential as a low-cost therapeutic drug to treat COVID-19 symptoms and suppress the replication of coronavirus inside the body.
One of the important objectives of green chemistry is the use of eco-friendly solvents and catalysts to perform chemical reactions.
As the COVID-19 pandemic swept around the world early this year, shortages of protective equipment such as N95 masks left healthcare workers little choice but to reuse the masks they had - increasing the risk of infection for both them and their patients.
Dermatology researchers at Henry Ford Health System, in collaboration with a team at the University of Michigan, have demonstrated that certain N95 respirators tainted with COVID-19 can be effectively and safely decontaminated for reuse using ultraviolet-C light (UV-C), a method commonly utilized for treating rare skin diseases.
Every time we eat, the glucose level in our body goes up. This spurs our pancreatic machinery into action and through intricate physiological mechanisms, appropriate amounts of insulin are produced, our blood glucose levels are controlled, and we remain healthy.
N95 respirators, which are widely worn by health care workers treating patients with COVID-19 and are designed to be used only once, can be decontaminated effectively and used up to three times, according to research by UCLA scientists and colleagues.
Two Rutgers-led studies have identified a more rapid method to decontaminate N95 masks using vaporized hydrogen peroxide – making reuse of masks more economically feasible and practical for health care workers on the frontlines against COVID-19.
Cough has many remedies, but one of the most popular ones is honey, which has been used for centuries. Now, new research claims honey may be a better treatment for cough and colds than over-the-counter medicines.
This spring, due to limited national supplies of N95 face masks, hospitals across the country asked the public and private companies to donate personal protective equipment (PPE), including many different types of masks, to be sure healthcare workers were protected while caring for patients.
Filter “paper” made from titanium oxide nanowires is capable of trapping pathogens and destroying them with light. This discovery by an EPFL laboratory could be put to use in personal protective equipment, as well as in ventilation and air conditioning systems.
The COVID-19 pandemic has shed new light on the needs for improved disinfection methods, both for individuals and facilities.
Inside the Mizzou Asphalt Pavement and Innovation Lab at the University of Missouri College of Engineering, Bill Buttlar normally leads a research team developing innovative ways to build better roads and stronger bridges.
