Hydrogen Peroxide is a chemical used in bleaches, dyes, cleansers, antiseptics, and disinfectants. In a concentrated form, it is toxic and irritating to tissues.
Blood transfusions can save the lives of patients who have suffered major blood loss, but hospitals don't always have enough or the right type on hand. In search of a solution, researchers have developed a promising substitute using blood's oxygen-carrying component, hemoglobin.
Findings offered by a University of Kansas researcher, identified as one of 20 'Must See Presenters' at the national meeting of the American Chemical Society in early April, suggest a possible therapeutic intervention for "chemobrain," the cognitive impairment plaguing up to a third of cancer patients following chemotherapy.
A research project conducted at the University of São Paulo in Brazil in collaboration with other Brazilian research institutions and abroad has revealed new aspects of the action mechanism of organic hydroperoxide resistance (Ohr) enzyme, which enables several species of bacteria to neutralize oxidizing substances released by the defense system of the host organism, be it a plant or an animal.
High-concentration peroxide, sometimes promoted in alternative medicine circles for cleanses or as a so-called "natural cure," can lead to numerous life-threatening ailments and death itself, according to a paper published online yesterday in Annals of Emergency Medicine.
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.
Researchers from the University of Basel in Switzerland have clarified the role of the enzyme MPO.
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.
Molecules with the potential to deliver healing power to stressed cells - such as those involved in heart attacks - have been created by University of Oregon researchers.
Sunlight allows us to make vitamin D, credited with healthier living, but a surprise research finding could reveal another powerful benefit of getting some sun.
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).
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.
Nagoya University researchers develop cold plasma-activated Ringer's solution for chemotherapy. The solution has anti-tumor effects in vitro and in vivo that derive from the lactate component.
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.
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 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 at Johns Hopkins Medicine report they have identified a biochemical pathway linking oxidative stress and the amino acid cysteine in Huntington's disease.
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.
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).
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).
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.
