Hydrogen Peroxide is a chemical used in bleaches, dyes, cleansers, antiseptics, and disinfectants. In a concentrated form, it is toxic and irritating to tissues.
A protein that helps keep our cell powerhouses working at a premium appears to also help make energy rapidly available when it's time to make new blood vessels.
Researchers at The University of Texas MD Anderson Cancer Center have developed a new radio-labeled molecule capable of selectively reacting with certain high-energy radicals that are characteristic of innate immune activity, which may allow a non-invasive approach to monitor inflammation in real time by positron emission tomography (PET) imaging.
After a spell of unexpected rain, before the harvest season, a farmer may be faced with the unpredictable problem of untimely sprouting of barley.
Unexpected rain before the harvest season leaves the farmer with a problem—untimely sprouting of barley.
Carthamin is a red pigment that stems from the yellow-orange corollas of safflower. Its usage as a red colorant can be traced back to ancient Egypt. In Japan it is named "beni" and has been used for dyeing textiles, coloring cosmetics and food, and as an herbal medicine for over 1400 years.
The discovery of antibiotics is a significant milestone, which saved many lives.
A recent study in Frontiers in Sustainable Food Systems shows that the fruits of a type of tomato plant send electrical signals to the rest of the plant when they are infested by caterpillars.
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.
Several biological processes are subject to rhythmic variations. Popular examples of this include the supposed circadian rhythm.
Rice University researchers have created a "defective" catalyst that simplifies the generation of hydrogen peroxide from oxygen.
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.
An international team comprising researchers from the University of Bristol, and Hunan and Central South Universities in China, have prepared biocompatible protocells.
High levels of reactive oxygen species, called oxidants, are detrimental to cells in all organisms and have been associated with ageing.
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.
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.
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.
Oxidative stress is the result of reactive oxygen species (ROS) generation, and can be damaging to cells and tissues.
Scientists in the United States have used a newly developed fluorescent imaging technique to create high-resolution maps of microbial communities on the human tongue.
Researchers at the Stanford School of Engineering have designed a technique for reprogramming cells to use synthetic materials, which the team provides, to create artificial structures that can perform functions within the body.
In a genome-wide CRISPR-Cas9 screen published in Nature Immunology in January 2020, a group of researchers described a potential universal target on cancer cells.
