Hydrogen Peroxide is a chemical used in bleaches, dyes, cleansers, antiseptics, and disinfectants. In a concentrated form, it is toxic and irritating to tissues.
Vitamin C is best known as a nutrient. In high enough doses, however, vitamin C also shows potential against many cancers, according to recent studies. To successfully develop vitamin C (chemically named ascorbic acid) as a medication, it is crucial to probe its concentration in the body, thus ensuring safe and effective doses.
Printed replacement human body parts might seem like science fiction, but this technology is rapidly becoming a reality with the potential to greatly contribute to regenerative medicine. Before any real applications, "bioprinting" still faces many technical challenges.
There's a continued drive towards making in vitro assays ever more translational towards in vivo models and ultimately the clinic. This ties in with the resurgence of phenotypic screening and is a response to the perceived poor translation of the traditional simple cell-based assays, often developed to study just single protein targets.
Manganese dioxide could make the preparation of micromotors increasingly cost-effective, opening up new avenues for their use, according to a new study from the University of Eastern Finland.
Stem cell researchers at Emory University School of Medicine have made an advance toward having a long-lasting "repair caulk" for blood vessels. The research could form the basis of a treatment for peripheral artery disease, derived from a patient's own cells. Their results were recently published in the journal Circulation.
A key enzyme that helps our proteins fold and function properly may also be a good therapeutic target to improve blood vessel health in diseases like diabetes and atherosclerosis, scientists say.
A Northwestern University research team has discovered how scalding heat and tissue injury activate an ancient "pain" receptor in simple animals. The findings could lead to new strategies for analgesic drug design for the treatment of humans.
Hospitals should design premises and adapt their infection control routines to a society that no longer has effective antibiotics, and that is vulnerable to fast-spreading global pandemics. This is argued in a new dissertation from Lund University in Sweden.
According to a new study, nurses who are work disinfectants continually through their careers are more likely to develop a chronic lung disease called chronic obstructive pulmonary disease (COPD).
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.
