Hydrogen Peroxide is a chemical used in bleaches, dyes, cleansers, antiseptics, and disinfectants. In a concentrated form, it is toxic and irritating to tissues.
During sepsis, cells are swamped with reactive oxygen species generated in an aberrant response of the immune system to a local infection.
The techniques used to clean and sterilize flexible ureteroscopes leave behind contamination including debris, residue, and bacteria, according to a new study being presented at the 44th Annual Conference of the Association for Professionals in Infection Control and Epidemiology.
Vaisala expands to a new area and launches a new probe for the measurement of vaporized hydrogen peroxide.
Vaisala expands into a new area of measurement by launching the HPP272 probe for the measurement of vaporized hydrogen peroxide. The HPP272 achieves accurate and exceptionally repeatable measurements.
Autonomous targeting and release of drugs at their site of action are desired features of nanomedical systems. Now, a team of Dutch scientists has designed a nanomotor that has these functions: An antitumor drug encapsulated in self-propelled, self-assembled stomatocytes is carried across the cellular membrane and released inside the cell upon a chemical redox signal that disassembles the vesicle membrane.
Enzyme Indicators (EI’s) have been proven as a revolutionary viable alternative to biological indicators (BI’s) for Hydrogen Peroxide decontamination validation.
Tests of cells collected from the umbilical cord blood vessel walls at birth can predict death or poor pulmonary outcomes in extremely preterm infants, say researchers at the University of Alabama at Birmingham.
Under normal conditions, the CHD4 protein is one of the good guys: it stops cells from transcribing faulty DNA, thereby eliminating potential mutation. But in colon cancer and perhaps other kinds of cancer as well, it appears that this protein becomes a kind of double agent, working for the enemy.
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.
