Hydrogen Peroxide News and Research

RSS

Hydrogen Peroxide is a chemical used in bleaches, dyes, cleansers, antiseptics, and disinfectants. In a concentrated form, it is toxic and irritating to tissues.

Single-molecule compounds may become basis for new antioxidant therapies

Treated particles of graphene derived from carbon nanotubes have demonstrated remarkable potential as life-saving antioxidants, but as small as they are, something even smaller had to be created to figure out why they work so well.

UI scientists reveal how high-dose vitamin C damages cancer cells

Vitamin C has a patchy history as a cancer therapy, but researchers at the University of Iowa believe that is because it has often been used in a way that guarantees failure.

Lactate component responsible for anti-tumor effects of plasma medicine, research shows

Physical plasma is one of the four fundamental states of matter, together with solid, liquid, and gas, and can be completely or partially ionized (thermal/hot or non-thermal/cold plasma, respectively).

Scientists explain concept of combining NO gas therapy with starvation of tumor cells for nanomedical treatment

Biocompatible nanocapsules, loaded with an amino acid and equipped with an enzyme now combine two anti-tumor strategies into a synergistic treatment concept. Researchers hope this increases effectiveness and decreases side effects.

WSU researchers develop novel technology to treat chronic wound infections

A WSU research team has successfully used a mild electric current to take on and beat drug-resistant bacterial infections, a technology that may eventually be used to treat chronic wound infections.

Research findings of protein may form foundation for new approach to antibiotics

Researchers have made the first-ever detailed, atomic-level images of a peroxiredoxin, which has revealed a peculiar characteristic of this protein and might form the foundation for a new approach to antibiotics.

Researchers explain why secondary infection with MRSA kills influenza patients

Researchers have discovered that secondary infection with the Methicillin-resistant Staphylococcus aureus (MRSA) bacterium (or "superbug") often kills influenza patients because the flu virus alters the antibacterial response of white blood cells, causing them to damage the patients' lungs instead of destroying the bacterium.

Researchers discover pathway linking oxidative stress and cysteine in Huntington's disease

Researchers at Johns Hopkins Medicine report they have identified a biochemical pathway linking oxidative stress and the amino acid cysteine in Huntington's disease.

Penn researchers use iron-containing nanoparticles to reduce plaque and prevent tooth decay

The bacteria that live in dental plaque and contribute to tooth decay often resist traditional antimicrobial treatment, as they can "hide" within a sticky biofilm matrix, a glue-like polymer scaffold.

Scientists clarify mechanism of defective immune defense in G6PD patients

Favism is a common hereditary disease, affecting around 400 million people worldwide. It is caused by a lack of the enzyme glucose-6-phosphate dehydrogenase (G6PD).

Oxford scientists introduce simple nano-electrochemical process for precise determination of erythrocyte count

Blood counts are routinely carried out before operations, in cases of infection, or when testing for a variety of diseases, such as anemia and leukemia. A key value in this test is the number of red blood cells (erythrocytes).

Titanium dioxide nanoparticles can have low-level effects on oxidative stress genes

A nanoparticle commonly used in food, cosmetics, sunscreen and other products can have subtle effects on the activity of genes expressing enzymes that address oxidative stress inside two types of cells.

DKFZ researchers develop new methods to study disease-relevant changes in production of oxidants

There are many false beliefs and myths about the role of oxidants and antioxidants in the human body. Traditionally, oxidants are presented as harmful and antioxidants as health-promoting. However, scientists have known for many years that endogenous oxidants are essential chemical messengers that help keep up the functions of the organism.

Amorphous iron nanoparticles have potential to kill tumor cells

Amorphous iron nanoparticles have a specific toxicity in tumor cells. In the journal Angewandte Chemie, Chinese scientists describe their design and synthesis of a special amorphous state of nanoparticulate iron, which can locally release reactive iron species in the acidic and hydrogen peroxide rich environment of cancer cells, providing new possibilities for theranostics and chemodynamic therapies.

New report raises questions about potential risks of chromium therapies

Chromium supplements are widely consumed for their antidiabetic activity as chromium(III) enhances the insulin sensitivity of cells. In particular, orthomolecular practitioners believe in the beneficial effects of providing the body with extra amounts of essential trace elements.
